Product Feature:
1, the disc lift check valve disc, seat around tunnel axis rotation, due to the channel into a streamline in the valve, flow resistance is smaller than l butterfly check valve, suitable for low velocity and flow not often change the large diameter of occasions, but should not be used for oscillating flow, its sealing performance than lift.Butterfly check valve points single type, double disc type and for the most part three, the three forms mainly by the valve diameter, the purpose is to prevent the backflow medium flow or stop, decrease hydraulic shock.
2, lift check valve: disc revolve around pin in the seat of the check valve.Disc check valve has simple structure, can only be installed in horizontal pipe runs, sealing is good.
3, lift check valve: disc sliding along the center line of the body of the valve.Pipeline check valve is a new kind of valve, its small size, light in weight and good processing technology, is one of the check valve development direction.But the fluid drag coefficient is slightly superior to swing check valves.

- Q: The working principle of the vacuum 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.
- Q: The air pipe is equipped with a check valve
- [air pipe with check valve] wind pipe with check valve, is to prevent changes in the direction of the wind generated negative pressure, the phenomenon of air intrusion.[duct] is a pipe system for air delivery and distribution.[check valve] refers to the flow itself depends on the media itself and automatically open and close the valve, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. 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: What does the number 16 on the check valve mean?
- This is the pressure level of the valve, which represents 16Kg, which is used for piping pressure less than this pressure.
- Q: I would like to ask you the following questions: Recently, the newly purchased three Lin electric water heater, installed in the upper layer of the five bathrooms, a faucet, that is left to wring out hot water, to the right to wring out cold water, mixed type.1 when there is no safety valve, the hot and cold flow is normal, but the check valve is dripping.2 manufacturers said that the high level to safety relief valve, dripping water and this also concerned, it took more than 100 safety valve, on the cold water pipe, but since then, hot water flow and its small, cold water normal, the check valve is still dripping.3 excuse me, check valve, check valve, safety valve is not a thing? Is it just a different name?4 is the relief valve the same as the relief valve?Now it's really a tough one. How do you solve the problem of small drop of water and hot water flow? The manufacturer said the pressure, but I very cold water washed!Thanks for the answer!
- Check valve and check valve is to prevent backflow of water, the valve is used for pressure relief, when the water heater pressure is too high, the pressure through the pressure relief valve and pressure relief valve on the other: for water, the quality is not good, the main problems for the water pressure is too low to cause, and check valve and pressure relief valve will further reduce the pressure, you can try to check off a try, I think the check valve is useless. If not, just add a booster pump to the cold water inlet.
- Q: Check valve and check valve
- The name is not the same, there is a check valve, there are video instructions, you can search the "Simon check valve.""
- Q: How do I install the pump outlet check valve?
- Because the check valve is easy to be damaged, therefore, the check valve shall be installed near the pump outlet, and a shut-off valve (usually ball valve or gate valve) is arranged on the top of the check valve, so that it is easy to overhaul. In order to facilitate the check valve before disassembly pressure relief, the valve itself is not equipped with a net valve, should be installed between the check valve and the shut-off valve with pressure relief valve.
- Q: Is the overcurrent valve a check valve?
- The flow valve is a check valve, the two principles of operation, performance, purpose is entirely different.The over-current valve is a protective valve in the pneumatic or hydraulic system that allows overpressure fluid to escape from the bypass.Check valve (check valve, also known as one-way valve or check valve), its role is to prevent the medium back in the pipeline.
- Q: An introduction to the check valve
- The check valve, also known as reverse flow valve, check valve, back pressure valve, one-way valve. This kind of valve is automatically opened and closed by the force produced by the flow of the medium of the pipeline itself. It belongs to an automatic valve.
- Q: What is the reason that the check valve does not stop water?
- 4 the vertical lift check valve shall be mounted on a vertical pipe.5, the lift type horizontal check valve shall be installed on the horizontal pipe.6. Do not check the weight of the valve in the line. The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system.
- Q: What does the check valve "H64" and "H14" mean?
- H check valve6 welding connection1 threaded connection4 swing check valveJB/T308-2004< valve type programming method >There should also be sealing surface material code and nominal pressure level
