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:The check valve for the printer doesn't have any air in it, but it doesn't come out. It still doesn't work
- From your personal statement, analysis of leakage, box of ink cartridges, ink the check valve back looked at the appearance of normal needle, injecting ink into ink box to see, I wish you good luckIn addition, I have not used check valve, the friend that has seen, personal speculation that there is a switch, should be misleading you
- Q:Should the pressure gauge be mounted before or after the check valve at the back of the pump?
- If installed after the check valve, no matter how the pump operation, will show the actual pressure in the pipe.In order to facilitate the replacement, you can install a small valve on the main pipe to connect the pressure gauge on the small pipe. When you change the pressure gauge, you only need to turn off the small valve
- Q:Can the check valves fit two in one tube? One up, the other down
- Launching, then you'd like to have a Sheung Shui at the front of the Sheung Shui
- Q:40 how large check valves are installed in the water pipes?
- Crown valve press40 of the pipe outer diameter of 48 DN40 check valve on it
- Q:How can the fast closing noise check valve prevent water hammer?
- Biaoguan valve that once the pump stopped, check valve spool in the spring or other auxiliary device for double end under the action of force balance in advance to the closed position, can greatly reduce the amount of water and initial water reflux falling height, water hammer force is calculated by gravity superposition, to reduce the amount of water is equal to the reduced gravity, but fell short height reduces the inertia time is relatively reduced speed, and can prevent the formation of destructive or reduce water hammer water hammer.
- Q:What kind of check valve is used in the sewage pump of sewage treatment plant?
- 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, DN50mmThe 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:Check valve can not stop water, how to solve?
- See if there is anything dirty inside! See if the valve is broken!
- Q:We are high-rise buildings, with the smart recharge meters, before always someone to reflect the water used soon, 27 tons of water in only a month has gone. Later I heard that the water meter in front of a check valve on it, but when the five tons of water after the use of nothing, and nothing. Why does that happen? Does the check valve stop the water meter from idling?There is a special case, thirty storey building, booster pump has a pressure in the debugging of the fifteenth layer of what, every time on the twentieth floor of the owners reflect his home water intermittent, sometimes when a shower suddenly no water, we always to reflect the property many times, we are the plumber debugging a few times, or not. Later said that can not be adjusted, and then the tune will burst, and this is how it happened? How can I solve this problem? Why didn't the owners of the thirty and fifteen floors reflect the shortage of water pressure? But the owners of the more than 20 floors are so unlucky?
- 4. conclusionMany reasons for water rotation, but on the whole can be divided into two: one is the subjective factors, namely subjective causes, such as construction acceptance, human responsibility caused by Water Leakage, original gas gathering, which can strengthen the construction management, improve the staff's work and to improve the level of responsibility. The two is the objective factors, the main characteristics of the water itself, by the characteristics of pipeline and the level of technology development in the external objective factors, on the one hand to work in the future continue to explore the improvement will be improved.
- Q:What are the brands of check valves?
- The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
- Q:Does FOTILE hood have check valve?
- Therefore, it is necessary to install a check valve at the flue port.
