valves\uff1b<\/span><span style=\"font-size: 1rem;\">This type of valve works by allowing flow in one direction and preventing flow in the opposite direction. Usually this kind of valve works automatically. Under the action of the fluid pressure flowing in one direction, the valve opens, and when the fluid flows in the opposite direction, the fluid pressure and the self-coincidence of the valve disc are used. Acts on the valve seat, thereby shutting off flow. Among them, the check valve belongs to this type of valve, which includes swing check valve and lift check valve. Swing check valves have a hinged mechanism and a door-like disc that rests freely on the sloping seat surface. In order to ensure that the valve disc can reach the proper position of the valve seat surface every time, the valve disc is designed in the hinge mechanism, so that the valve disc has enough space to rotate and make the valve disc truly and comprehensively contact the valve seat. The check valve is often used as the bottom valve of the pumping device, which can prevent the backflow of water. The combined use of the stop valve and the globe valve can play the role of safety isolation, but the disadvantage is that the resistance is large and the sealing performance is poor when closed. Check valves may also be used on lines supplying auxiliary systems where pressure may rise above system pressure.\u00a0<\/span><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4b2488f elementor-widget__width-auto elementor-widget elementor-widget-button\" data-id=\"4b2488f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-xl\" href=\"#elementor-action%3Aaction%3Dpopup%3Aopen%26settings%3DeyJpZCI6IjEwNjEiLCJ0b2dnbGUiOmZhbHNlfQ%3D%3D\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Send Inquiry Now<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-295e0770 elementor-section-content-middle elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"295e0770\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-33 elementor-top-column elementor-element elementor-element-1c89c26a\" data-id=\"1c89c26a\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-4e3d8bd elementor-widget elementor-widget-heading\" data-id=\"4e3d8bd\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">How to determine the size of the check valve\uff1f<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-38557eb2 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"38557eb2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e182353 elementor-widget elementor-widget-text-editor\" data-id=\"e182353\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<div>Chatter, which occurs when the valve is oversized, is one of the most common causes of check valve failure. If the valve vibrates a lot (repeatedly opening and closing the valve), it can cause premature wear of internal parts, which can lead to spring failure, damage to the poppet, or deformation of the valve seat, all of which can affect how the valve seals back into flow. Pipe size and the need for maximum Cv (flow coefficient) are common ways to select a check valve. Unfortunately, this approach completely ignores the fact that the check valve is sensitive to flow conditions. It is important to remember that the size of the check valve should be based on the actual application, not the size of the pipe. The poppet needs to be stable against the internal stop in either the open or fully closed position; this will prevent chattering (chatter or excessive vibration) and therefore premature failure due to excessive wear of the internal parts. Properly sizing check valves minimizes the possibility of chattering. By understanding temperature, pressure, media, flow and viscosity, we can help determine the flow characteristics of a valve when it is in use. We want to ensure that the pressure drop across the valve is at least 1 psi, but it is better to choose a larger pressure to ensure the valve is in the fully open position. Round Valve Technology offers a wide variety of check valve product lines with various spring ranges and seal materials to suit a variety of applications.\u00a0<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b2356b6 elementor-widget__width-auto elementor-widget elementor-widget-button\" data-id=\"b2356b6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-xl\" href=\"#elementor-action%3Aaction%3Dpopup%3Aopen%26settings%3DeyJpZCI6IjEwNjEiLCJ0b2dnbGUiOmZhbHNlfQ%3D%3D\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Send Inquiry Now<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-33 elementor-top-column elementor-element elementor-element-4a7bb282\" data-id=\"4a7bb282\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-436f7738 elementor-widget elementor-widget-heading\" data-id=\"436f7738\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Check valve diagram<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d609ca2 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"d609ca2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-515c4c31 elementor-widget elementor-widget-text-editor\" data-id=\"515c4c31\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>This is a schematic diagram of the structure of the swing check valve, which is a one-way valve.

Before installing the check valve, you must carefully check the appearance, brand, etc. of the check valve to see if it meets the relevant standards stipulated by the state, and the check valve should be tested for strength and tightness. After confirming that it is qualified, can be installed and used.<\/div><div>2. If the check valve is to be installed correctly, the installation height of the check valve, the inlet and outlet directions of the water flow, etc. must comply with the relevant installation specifications, and the flow direction of the internal medium should be the same as that marked on the check valve. The direction of the arrow is the same, as for the connection position, it must be tight and firm.<\/div><div>3. When installing the check valve, you should first observe the two ends of the check valve in detail, then find the water inlet port of the check valve, and then connect the water inlet port of the check valve and the water outlet port of the water pipe together. , When the water flows in from the inlet port of the check valve, the check valve will start to operate.<\/div><div>4. The water inlet port of the check valve is usually located at the lower position of the check valve, and the water outlet port of the check valve is generally located at the upper position of the check valve. When the water pressure of the water flowing into the check valve exceeds a certain value, the valve of the check valve will automatically open, and then water will flow out of the water outlet port of the check valve.<\/div><div>5. When the water pressure of the water flowing into the check valve is lower than a certain value, the phenomenon of backflow of water will occur in the check valve, and the valve of the check valve will also be automatically closed, and no water will flow out of the water outlet port. Through the above water flow phenomena, it can be detected whether the check valve is installed correctly.<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f1893f7 elementor-widget__width-auto elementor-widget elementor-widget-button\" data-id=\"f1893f7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-xl\" href=\"#elementor-action%3Aaction%3Dpopup%3Aopen%26settings%3DeyJpZCI6IjEwNjEiLCJ0b2dnbGUiOmZhbHNlfQ%3D%3D\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Send Inquiry Now<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-33 elementor-top-column elementor-element elementor-element-4d665f8e\" data-id=\"4d665f8e\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-3418027 elementor-widget elementor-widget-heading\" data-id=\"3418027\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Should the check valve be installed before or after the pump?<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6dd8d9c elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"6dd8d9c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6e3f30a elementor-widget elementor-widget-text-editor\" data-id=\"6e3f30a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<div>The check valve can be installed before and after the water pump.
