Q: Check valve H41T-16. What are the numbers and letters in it?: H stands for check valves, 4 for flanges, 1 for lift, T for seal, and 16 for pressure

Q: What is the HH44X-16 H of the double acting slow closing check valve? Can you explain it in detail?: 1. The first H is the meaning of the check valve (the first letter of the Chinese phonetic alphabet). The second H is the meaning of "slow closing" (the first letter of the Chinese phonetic alphabet).

Q: Check valve note BC/PISTON: SPR-L what does that mean?: BC==Bolted Cover/ bolted bonnetPISTON== lifting typeSPR-L==Spring-loaded/ is loaded with springsTogether, it is: a spring-loaded check valve. Bolted bonnet (this is common)

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!: Frequency conversion and it does not matter, the inverter is to speed down, so that the pump has a suitable flow and lift. This valve can not go.

Q: Does the check valve differ in front of the water meter and press it behind the water meter?: The combination of the meter and check valve must be the check valve behind the meter because the purpose of the check valve is to prevent the water meter from reversing and to protect the rotating vulnerable parts in the water meter.. At present, there are water meters with check valves, which can simplify installation and provide efficiency

Q: How many kinds of check valves should be used?: Ball check valve because the sealing part is covered with rubber ball, therefore, good sealing performance, reliable operation, anti water hammer performance; the seals can be a single ball, they can make more balls, so you can make large caliber. But its seal is wrapped in rubber hollow sphere, does not apply to high pressure pipeline, only applies to the middle and low pressure pipeline.Because the shell material of spherical check valve can be made of stainless steel, sealed hollow sphere parts can be coated PTFE plastics, can also be applied in the pipeline so general corrosive medium.The check valve in the working temperature between -101~150 DEG C, the nominal pressure is less than 4.0Mpa, nominal in the range of 200~1200mm

Q: Is it necessary to install a check valve for suction well pumping well? If you need to install what kind of check valve (about lifting, butterfly valve, also a what to forget), which (installed in the water outlet, water inlet, or water pipe), ask again need to install the filter valve? I do not understand, ask for expert doubts! Thank you very much!: 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: What are the differences between the vertical check valve and the horizontal check valve in function and principle?.: The vertical check valve and horizontal check valve are functionally and functionally indistinguishable.The difference between vertical check valve and horizontal check valve:Horizontal check valves, mounted in horizontal pipes, have the same shape as the globe valves; vertical check valves are attached to vertical pipes.Check valve is open and close parts, depending on the flow of medium and power to open or close, to prevent media backflow valve called check valve. The check valve belongs to the automatic valve, mainly used for one-way flow of medium pipe sleep, allowing only medium to flow in one direction, in order 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.

Q: What are the differences between the vertical check valve and the horizontal check valve?: The structure principle is the same, but the cost and volume are different, there is nominal pressure difference, the use place is different

Q: What does the H/F/P stand for in the check valve H41H/H41F/H41P?: Respectively, the valve seat sealing surface is made of alloy / fluorine plastic / stainless steel.
