- Q:Is it necessary to install a check valve in front of the water meter? Does the water company have a definite requirement?
- To install a check valve, or, when the tap water supply, there is water in the pipe will flow back, but the water meter will not reverse, if there is air in the water pipe, this phenomenon continues to cycle, virtually increase the number of water charges
- Q:How do I use the triangle and check valves?
- The triangle valve is used for connecting taps and water equipment. Check valves are used to prevent backflow of water.
- Q:Is it necessary to install a check valve for household well pumping?
- 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, DN50mm.The 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:Is the check valve and relief valve something?
- Not the same thing!!! Installed on the water heater will not have too much money, less than 10 should be enough, but most of the water heaters are non - targets, may not be too good to match, you'd better go to a larger plumbing market
- Q:What is the function of the check valve?
- The function of the check valve is to prevent the medium from flowing back! Check valves, which are commonly known as check valves! Backflow of medium will cause the reverse of pump impeller, which may lead to the burnout of pump! Pumps used in industry are expensive nowadays! Ha-ha！ The check valve just protects the pump and piping!
- Q:Check valve h42h-dn80 what does that mean?
- According to the provisions of the JB/T 308-2004 valve type programming method:H = check valve4 = connection: flange2 = structure form: vertical lifting typeH = sealing surface material: Cr13 stainless steelDN80== nominal diameter: 80mm
- Q:Does one-way check valve affect water flow?
- The water inlet of the household water heater is equipped with a triangle valve, which will not affect the flow of water, and be convenient for maintenance and inspection
- 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:What does the check valve "h61h-25 H" mean?
- From the model analysis, for the cast steel welding lift check valve, it depends on your valve is not it
- Q:What are the differences between the vertical check valve and the horizontal check valve?
- The main difference is whether the valve center and valve seat are placed horizontally or vertically. It is usually designed with the pipe
