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: What are the differences between different check valves applications? For example, is the fire pump outlet swing check valve or a silent check valve? According to 35How to recognize single wall corrugated pipe and double wall corrugated pipe? Which is better?.What's the use of the silent check valve? And the bellow problem below, is there no answer?
- 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: Is the hdf41x 1.6Mpa a check valve?
- Backflow prevention device according to tap water supply equipment, especially drinking water pipe back to serious pollution, and effectively prevent the pollution device under the condition of a strictly limited hydraulic control assembly pipeline water only one-way flow of development, its function is to prevent backflow pipeline media in any condition, in order to avoid the purpose of backflow pollution.
- Q: The difference between check valve and check valve
- 1, one-way valve: is a typical seat valve, one-way valve Check, Valve, also known as check valve or check valve. Used in hydraulic systems to prevent reverse flow of oil flow. There are two one-way valve one-way and right angle type. Straight through one-way valves are threaded and installed on the pipe line. The right angle one-way valve has threaded connections, plate connection and flange connection in three forms. Liquid control check valve, also known as blocking valve or pressure valve, which is the same as one-way valve, used to prevent reverse flow of oil. But in the hydraulic circuit needs the oil flow reverse flow, but also can use the control oil pressure, opens the one-way valve, causes the oil flow to be possible to flow in two directions. The hydraulic control check valve adopts a conical valve core, so the sealing performance is good. When the closed oil circuit is required, the valve can be used as the one-way locking of the oil circuit to maintain the pressure. Liquid control check valves control the leakage of oil, there are two types of internal and external leakage. In the oil flow reverse outlet, no back pressure in the oil pipeline can be used to vent type; otherwise, need to leak type, in order to reduce the control oil pressure2, check valve is only one kind of valve, it can be said that one-way valve is a kind of check valve,
- Q: Check valve does not automatically check back, how to adjust?
- 7, when installing check valve, should pay special attention to medium flow direction, should make medium normal flow direction and the direction of the arrow on the valve body is consistent, otherwise it will cut off the normal flow of media. Valve should be installed at the bottom of the pump suction pipe.The general formula 8, lift check valve should be installed in horizontal pipe, vertical lift check valve and bottom valve is usually installed in a vertical pipe on the road, and the bottom-up flow of media.9, the check valve closes, will produce water hammer in pipeline pressure, will lead to serious damage to the valve and piping or equipment, especially for the big pipe or high pressure pipeline, it should pay attention to those who use check valve.
- Q: How much is the check valve for the concrete pump?
- 31 concrete pump price ranging from 15W to 60W, different configurations have different prices, which one do you want?
- Q: What type of check valve should be installed before the suction pump?
- Swing, turn, or automatic (note, anyway) can be.
- Q: What are the specifications of the DN200 check valve?
- DN200 is a specification.The principle of the check valve, the check valve, the opening and closing parts, depend on the flow of the medium and the power to open or close on its own, so as to prevent the backflow of the medium, called the 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. The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve. The lift check valve can be divided into two types: vertical and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly check valve for straight through, more than a few kinds of check valve, in the form of connection can be divided into thread connection, flange connection and welding three. A check valve is a valve that automatically prevents the flow of fluid. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the exit side, the valve automatically closes under the influence of fluid pressure, gravity and other factors to prevent fluid flow backwards.
- Q: See English design drawings, found the check valve to a lot of good variety, do not know how to translate, please come and see God, and generous with your criticism.CHECK VALVE I search on the Internet, that is, the meaning of the check valve, but so many kinds, really do not know what it means, not only did not see, never heard of.CHECK VALVE - ANGLECHECK VALVE - ANGLE STOPCHECK VALVE - ANTI WHIPCHECK VALVE - STOPCHECK VALVECHECK VALVE - TILTING DISKCHECK VALVE - WAFERCHECK VALVE - Y STOPHigh reward oh, good answer, I will give you a big additional scores drop, huh, worried about kazakhstan. StopPlease make a explanation according to my offer English name, online copy paste do not explain visual satisfaction, I will give you an additional 20~100.Starbooks | browse 5128
- This is more challengingI think these are all check valves, but the designer notes the structural features of the check valve itself to make it easy to distinguish.CHECK VALVE - ANGLE, if translated as "angle valve" must be wrong, but in the back of the check valve with an angle, will not be the valve is not an ordinary check valve, but the right angle structure of the check valve? Pure speculation. Right angle check valve.CHECK VALVE - ANGLE STOP ibid., the check valve of the right angle structure, mainly acts as a cut-off. Right angle stop valve.CHECK VALVE - ANTI WHIP physics, there is a professional interpretation, (anti whip device) pipe anti swing device, I guess there should be the meaning of anti shock, it is also one of the role of one-way valve. Here I translated as anti shock valve.The CHECK VALVE - STOP is different from the ANGLE STOP, and the ordinary structure is interpreted as a stop valve here.CHECK VALVE check valveCHECK VALVE - TILTING DISK tilting disc valve, this should be indicated on the special check valve structure, inside the JBT308, check valve structure with the valve structure, this should be inside the swing valve a.CHECK VALVE - WAFER flat plate check valve.The CHECK VALVE - Y STOP Y check valve is also a structural form. This does not understand, it translates into Y stop valve.
- Q: Does the regulator have a check action? If yes, can I use it as a check valve?
- The regulating valve is to adjust the pressure, and the check valve is to prevent the backflow of fluid.Clear division of labor, non-interference in each other.Even if some special pressure regulating valve has a non-return function, it can not be used as check valve.It is recommended to install a check valve on the pipe to make sure it is safe.Hope to be of help to you!
