Q: Why is the water ring vacuum pump equipped with check valves?: The check valve is a one-way valve, the instantaneous vacuum of the stopping pump is higher than the pump cavity, and the gas enters the pump cavity from the exhaust port, and the water pressure is connected to the vacuum pipeline, and the function of the check valve is to prevent water from entering the pipeline

Q: What is the material of H41W-16's check valve?: According to: JB/T 308-2004 "valve type programming method"H check valve4 flange connection1 lift through straight through valve passageW sealing cover for body material16 nominal pressure PN16When the nominal pressure is less than or equal to PN16, do not mark the material code of the valve body, the valve body material is gray iron

Q: Where can I find the good check valve?: Northeast, I think the quality is better

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

Q: Only one is a soft seal and one is hard sealed: Not the same model. The rubber valve check is HC44X, and the swing check valve is H44H

Q: Check valve h44h-25p what does that mean?: H- check valve code4- flange connection4- rotary single structureH sealing material is Cr13 stainless steel25-25 kg pressure 2.5MPaP- stainless steel 304

Q: Does the check valve of the flue of the range hood work?: Lampblack machine flue check valve is generally installed in the hood outlet check valve, the valve has two blades, a reset spring, exhaust hood leaf was blown open, lampblack machine stop when the blade is spring pressed into the closed state, now is basically take lampblack machine the check valve check valve, but the general tightness is not very good, open the hood can be seen around the gap. According to everyone's reaction and market similar products sold well, smoke hood comes with soot hood flue check valve basically does not work.The picture of the check valve of the flue of the range hood is as follows:

Q: Should the flue check valve be made by the civil team or the installation team?: The kitchen flue and check valve are all constructed by civil engineering.

Q: We are high-rise buildings, with the smart recharge meters, before always someone to reflect the water used soon, 27 tons of water in only a month has gone. Later I heard that the water meter in front of a check valve on it, but when the five tons of water after the use of nothing, and nothing. Why does that happen? Does the check valve stop the water meter from idling?There is a special case, thirty storey building, booster pump has a pressure in the debugging of the fifteenth layer of what, every time on the twentieth floor of the owners reflect his home water intermittent, sometimes when a shower suddenly no water, we always to reflect the property many times, we are the plumber debugging a few times, or not. Later said that can not be adjusted, and then the tune will burst, and this is how it happened? How can I solve this problem? Why didn't the owners of the thirty and fifteen floors reflect the shortage of water pressure? But the owners of the more than 20 floors are so unlucky?: 4. conclusionMany reasons for water rotation, but on the whole can be divided into two: one is the subjective factors, namely subjective causes, such as construction acceptance, human responsibility caused by Water Leakage, original gas gathering, which can strengthen the construction management, improve the staff's work and to improve the level of responsibility. The two is the objective factors, the main characteristics of the water itself, by the characteristics of pipeline and the level of technology development in the external objective factors, on the one hand to work in the future continue to explore the improvement will be improved.

Q: What is the difference between the H44H check valve and the H41 check valve?: The lift type horizontal check valve shall be installed on the horizontal pipeShanghai reliance Valve Manufacturing Co., Ltd.Lifting type is more swing type, good sealing, large resistance to fluid, horizontal should be installed in the horizontal pipe, vertical mounted on the vertical pipe;Swing type check valve installation location is not restricted, it can be installed in horizontal, vertical or inclined pipeline, such as installed in the vertical pipe, the flow direction of medium to bottom up; x0d
