Advantage

 

1.Lift check valve is self-sealing valve. The disc can be acted by the flow which can protect against the media flow back.

2.The disc with spring can keep the valve work in any direction.

3.Reasonable structure, reliable sealing, excellent performance and attractive appearance make a TKFM valve.

Q: The working principle of the vacuum check valve
A vacuum check valve is a valve that automatically prevents fluid from flowing back. 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.Vacuum check valve according to the structure, can be divided into lifting check valve, swing check valve and butterfly check valve three.
Q: Can the check valve be used on the steam pipe?
The check valve can be used on the steam pipe, but only the right material.General steam pressure WCB, temperature and pressure with the then high chromium molybdenum steel. The inside of the valve should be taken into account, depending on the pressure difference.
Q: My house is public flue, a total of six floor I live five floors, with the side suction hood, hood in the windy outside started as soon as the check valve pops ring from occupancy, have what way?
Do you think the situation in the wind ` a valve installed in the opposite direction of the flue you can, you should pay attention to when installing wind don't understand the whole, an anti air valve system, like on the wall in the general store has large lampblack machine. Or you in the hood where to buy, you can go to a can go, I also bought the lampblack machine, where he will give you, or call at the time according to the hood people to give you what you can handle.
Q: Why can't parallel check valve be installed firmly?Anonymous browsing | 51 times
The vertical installation is easy to cause the valve core of the check valve to clamp off or fall off, and lose the function of checking back. The direction of the check valve is restricted seriously from any direction of the medium
Q: What are the features of axial check valves?
Axial flow check valve (GB/T 21387-2008) by the standardization of the national valve technical committee (SAC/TC 188). The drafting unit: Shanghai Huatong Valve Co., Ltd., Ningbo aimeike copper valve valve Co. Ltd. Shanghai zhengfeng. Main drafters: Zhang Yonghui, Liu Tienan, Zheng Xuezhen, Chen Tiewang, Meng Aimin.

Q: Butterfly check valve should be equipped with special flange for butterfly valve
No, with a special appearance Jansen point flange butterfly valve. It can barely be installed without special flanges
Q: Back pressure valve and check valve difference
Oil is generally put into the wells of the check valve calling back pressure valveCheck valve is a general name, mainly lifting type and swing type.
Q: What is the function of the ventilator's check valve?
When the soot exhauster stops working, the one-way valve plate is automatically closed under the action of gravity, and the fume passage is isolated from the common flueThe smoke in the flue doesn't flow back in.
Q: How many kinds of structure are there in the check valve?
1. The structure of the lift check valve is similar to that of the globe valve. Its valve moves up and down along the central line of the channel. The action is reliable, but the resistance of the fluid is large. It is suitable for small caliber occasions. The lift type check valve has an air passage type
Q: Is the check valve a check valve? What is its main purpose?
Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline.
