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: Does the check valve differ in front of the water meter and press it behind the water meter?
- According to the specification, check valve (check valve) should be installed behind the watch. If it is placed in front of the meter, it will cause the meter to be inaccurate and damage the meter parts.
- Q: What's the difference between check valves and non-return valves?
- 2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.3, swing type: liquid through the valve body, relying on the pressure to open the side of the rotating valve flap,After the pressure is lost, the disc depends on its back weight and the reverse liquid pressure seals the disc.
- Q: Should the kitchen check be mounted on the wall or on the hood?
- It should be mounted on the wall. If you have more questions, click ID.
- Q: How can the check in the faucet prevent water from flowing backwards?
- Not to prevent backflow, is able to quickly shut the water, for triple bathtub, can effectively stop the conversion between the bath and small shower water, there is a spring, when the water pressure will be water, a small amount of Water Leakage was shut up
- Q: Circulating water check valve, I want to ask is not greater than DN600, you can use HBH747H hydraulic butterfly valve closed butterfly valve, less than DN600 of HD43X slow butterfly butterfly check valve, what does hydraulic check mean? Need hydraulic?
- Greater than DN600, you can use HBH747H hydraulic butterfly butterfly valve closed, less than DN600 with HD43X slow butterfly butterfly check valveThis is the usual selection, not necessary, there is no provision, but this choice is not wrong. There are, of course, other types of check valves.The hydraulic check valve is hydraulic, and the Baidu library contains instructions for the HB series and the HD series hydraulic check valves
- Q: What are the ten major brands of copper check valves?
- I knew that:1, Amico2, Jie Kelong3 crown4, good day5, KITZ
- Q: What type of check valve is the h61y-40 check valve?
- I. lift check valves: check valves that slide along the vertical centerline of the valve body. The lift check valves can only be installed on the horizontal pipe. The disc can be used in the high pressure small bore check valve. The valve body of the lift check valve is the same as the cut-off valve (which can be used with the stop valve), so it has a large coefficient of fluid resistance. The structure is similar to the cut-off valve, the valve body and the disc are the same as the cut-off valve. The lower part of the upper valve and the valve cover processing guide sleeve, the valve in the valve lift free guide simple simple light driven, when the medium downstream, the valve thrust open by the media, when the media stopped flow, the valve by the self vertical landing on the seat, preventing the media from the upstream effect. Straight through lift type check valve medium channel with import and export channel direction perpendicular to the valve seat; vertical lift check valve, the media import and export channel in the direction of the same direction with the valve seat, the flow resistance is smaller than the straight through.
- Q: Is it necessary to install a check valve for suction well pumping well? If you need to install what kind of check valve (about lifting, butterfly valve, also a what to forget), which (installed in the water outlet, water inlet, or water pipe), ask again need to install the filter valve? I do not understand, ask for expert doubts! Thank you very much!
- Selection of check valve for pump outlet check valveGeneral pump station project, for the pump outlet check valve, the following principles should be observed;The outlet check valve shall be used when the diameter of the outlet pipe of the pump is smaller, that is, DN50mm.The pipeline of the pump outlet pipe diameter DN is larger than 50mm, should be used in swing check valves can be installed horizontally or vertically. Swing check valve to rotate around the shaft, the fluid resistance is generally less than the lift check valve, which applies to the larger diameter of the occasion, the installation location restrictions, usually installed in horizontal pipelines, it applies with large caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves for medium and medium duty applications. Large diameter pipeline using single swing check valve, in order to reduce the water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double valve swing check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a fast check valve. Multi disc swing check valve is suitable for large diameter pipeline
- Q: How to use the check valve when the size of the pressure?
- 1, the use of check valve, the pressure level should be the size of the pipe corresponding to the pressure level.2, check valve and other valve class, the pressure levels for 0.6Mpa, 1Mpa, 1.6Mpa, 2.5mPA, 4mPA, 6 Mpa...... Wait。 If your pipe is between standard pressure, use a higher pressure grade. Such as: pipe pressure 1.8Mpa, the minimum choice of 2.5Mpa check valve.
- Q: What is the difference between the check valve and the check valve?
- 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.3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.
