Usage of Wafer Dual Plate Check Valve
Wafer Dual Plate Check Valve is used in pure line and drain line in many professions such as industry, environment protection, water treatment, high-rise building etc. The check valve is wafer-style, butterfly plate is composed of two semi-circle plates, can be reset by force of spring. The sealing face can be made from ontology surfacing wear-resistant material and rubber bush. This material is widely used, excellent sealing effect.

- Q: I installed here in the water pump inlet, water pump with a 100 tons of water tank, there are many pumps, long time running, the pump will heat the cylinder, there is no water in the cylinder, the pressure does not go. The water pump is imported. Is the check valve broken or is the installation position wrong?
- I told you what the meter said, "check the vacuum meter, and see if the vacuum gauge is pulled down." Without vacuum, there is air, and the possibility of pipeline leakage is greater. Upstairs that the pump is too small power is also a reason, the valve inside the valve holder is a copper block, there is not enough pumping force is not up. If the pipeline is short, that remove the valve tray, the water did not Xikou many words, direct pumping can be pumped up for a moment. Or replaced by the valve stop valve, turn off the valve, the water pump from the water diversion valve. In the opening of the pump at the same time, open the valve, take out the vacuum, there is no valve support will be easy to bring water. Check valve is generally not broken, the problem may be in the pipeline or pump. The pump long time idling is taboo, no water cooling, will be broken, must be careful next time.
- Q: What's the function of the small check valve on the deep well pump? Solve!When the deep well pump works, it does not move inside! Under great pressure！ There is a hissing sound when the deep well pump doesn't work! The air is in! Will it lead to the water in the room? There's a lot of air in it!
- This valve is to stop the pump when the intake, through the intake of water to cut off the backflow, to prevent water from being returned to empty, the air can not enter the valve above the part of the water pipe, rest assured
- Q: Detailed distinction between backflow preventer and check valve
- The backflow preventer consists of two separated check valves and a drain valve. Due to the local head loss of the check valve, the pressure in the middle cavity is always lower than the pressure at the inlet. This pressure difference causes the drain valve to be closed and the pipe is in normal water supply. In abnormal pressure (i.e., the outlet pressure is higher than that of the middle cavity), even if the two check valve can not reverse sealing, safety relief valve can automatically open the reverse water emptying, and the formation of air separation, ensure the health and safety of water upstream.Check valves are plain check valves, only one side seal. Backflow preventer is more expensive than ordinary check valve. Double protection and heavy protection!
- 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: 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: How much is the 6 point check valve for the water pipe at home?
- Different places, different prices, it is estimated that 20-30 copper. Complete check is impossible, and the effect depends on the actual situation,
- Q: How to control the common flue return and smoke return?
- How to control the common flue return valve, smoke return to smoke, kitchen flue check valve string smoke smoke? This is everybody wants to know about the fault, the most important problem is to put on the wall of the check valve is not sealed, now on the market to sell the check valve check valve check valve is not sealed, the check valve inside the material generally for metal, plastic. Check valve is the main thrust itself hard material, the valve body and so hard hard together with the no seal function, this is the public flue check valve to return back to tobacco smoke, kitchen flue non-return valve on cigarette smoke leakage of the major mistakes!Now houses are tall buildings, kitchen flue only one, every household fumes are discharged inside. Governance public kitchen flue, non-return valve, smoke, smoke, smoke and smoke leak is very simple, we designed a flue check valve, perfectly solved all the problems of soot backflow. Our flue check valve is the use of silicone sheet with soft seal, as long as a closed, a little smoke can not enter, and structure of the ordinary check valve is completely different, can thoroughly solve the oil return, to play the role of deodorant, anti back. And exhaust air super large, up to 180MM, installation is very convenient, they can be installed.
- Q: What can I do with the lift check 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. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure.
- Q: There is a check valve at the inlet of Haier electric water heater to prevent water from flowing back. Because there are many hot water used in the house, should the hot water be fitted with check valve?Can the hot water outlet be fitted with check valves? The hot water pipe is too long for hot water to flow back into the heater... Is it possible to install two check valves to affect the normal use of the heater?
- Hot water outlet should be equipped with check valve, for the following reasons:Closed type electric water heater in the outlet by one or more water control valves and water storage type electric water heater, and work in tap water under pressure. The utility model has the advantages of flexible installation position, high water outlet pressure, small heat loss, etc.. But because its inner liner is working under pressure, it needs thicker material and high manufacturing process. The outlet of open type electric water heater is opened and water is controlled by a valve on the water inlet pipe.
- Q: What are the main types of check valves?
- Check valve (Check Valve):1, according to the structure, can be divided into lifting check valve, swing check valve and butterfly check valve three.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 is straight through type.These types of check valves can be divided into three types: thread connection, flange connection and welding.
We mainly produce various check valves (for example,single disc swing check valve,double disc swing check valve,ball check valve,lift check valve, butterfly valves,diaphragm valves ,ball valves and so on).
