Usage/Applications Of Iron Check Valve：
Check valve is to rely on the flow of the media itself and automatically open, close the valve flap, used to prevent the media back valve, also known as the check valve, Dan Xiangfa, counter flow valve, and back pressure valve.
Check valve is an automatic valve, its main role is to prevent the media back, to prevent the pump and drive motor reversal, as well as the release of the container medium.

- Q:Check valves - check valves - what's the difference between one-way valves?
- Are check valvesCheck valves are widely used and there are many kinds of check valves. The following are common water supply and heat check valves:1, spring: the liquid from the bottom up, rely on the pressure spring controlled valve, the pressure disappears, the spring force the valve, sealing liquid backflow. Often used in the smaller diameter check valve.2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.
- Q:Check valve can not stop water, how to solve?
- Valve is broken, change one, my family is like this
- Q:What is the function of the check valve in the pipeline?
- Check valve, also known as one-way valve or check valve, refers to rely on the media itself flow and automatically open and close the valve flap, used to prevent the media back flow valve, also known as check valve, Dan Xiangfa, counter flow valve and back pressure valve.Effect：The function is to prevent backflow of medium in the pipeline. Pump water off the bottom valve check valve also belongs to class. The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents.Check valve installed in the pipeline system, the main role is to prevent media backflow, check valve is a kind of pressure on the media to open and close the automatic valve. The clip type check valve applies to nominal pressure PN1.0MPa~42.0MPa and Class150~25000; nominal diameter DN15~1200mm and NPS1/2~48; work temperature -196~540 degrees of various pipelines, used to prevent medium flow back. By choosing different materials, it can be applied to many mediums such as water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and uric acid.
- Q:What does the H/F/P stand for in the check valve H41H/H41F/H41P?
- The first H represents the check valve, the 4 represents the flange, and the 1 represents the lift type, and the second H represents the seat seal surface. The material is alloy steel or stainless steel. The P H41P said seating for boron steel
- Q:What does the check valve h44t-16 mean?
- Flanged swing check valve [H stands for check valve, 4 represents flange, 4 represents structural form (swing type), T represents internal copper alloy, and 16 represents pressure 16 pressure. I hope it will help you
- Q:What's the difference between a throttle valve and a check valve? Are they the same?
- The principle is very simple, just like upstairs said, like a revolving door, this is the swing test. There are lifting type, it is unknown.And "throttling" is to reduce the pressure of the fluid. In the pipeline, the fluid through the throttle valve, through the hand wheel or other transmission way to adjust the size of the internal channel, so that the flow of fluid flow down, to save traffic flow.
- Q:Is the flue check valve the same as the flue check valve? What's the difference?
- The same thing, different expressions, that is, in order to prevent channeling smoke smell of Dongdong
- Q:Check valve and check valve
- Check valve, also known as check valve, are to prevent backflow of a medium valve
- Q:Ask questions about the installation of check valves after water meters
- Generally installed after the water meter. The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter. A check valve is installed after the water meter, so that the situation can be avoided.
- Q:Check valve is 150, why not put 150 of the smoke pipe?
- DN150 check valve, it is possible that the internal path is less than the required value of 5mm-10mm. Therefore, the 150 outer diameter of the smoke pipe is not up.
