Q:Check valves - check valves - what's the difference between one-way valves?: 3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar

Q:Circulating water check valve, I want to ask is not greater than DN600, you can use HBH747H hydraulic butterfly valve closed butterfly valve, less than DN600 of HD43X slow butterfly butterfly check valve, what does hydraulic check mean? Need hydraulic?: If it is water medium butterfly valve, in fact, the same, are used to prevent the media back of the valve, on the models are manufacturers themselves, there is no uniform standard, but only in the use of media on the difference.Butterfly buffer check valve is to rely on the flow of the media itself and automatically open and close the valve, used to prevent the media back of the valve, also known as check valve, one-way valve, counter flow valve, and back pressure valveMicro resistance slow closing check valve, also known as check valve, its role is to prevent the medium back flow in the pipeline.

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?: Is the check valve installed at the inlet or outlet of the pump? Mainly to see whether the water pump suction or press in? There are other factors, such as pressing first class. Generally both sides will be installed, each has its own role, but to look at the type of your pump and other parameters, you describe the situation is too simple to point out in detail, such as specific is that a few, or all? Also, how high the pump needs to be played, and the pressure is often determined. The check valve is installed on the water outlet side of the pump. I simple analysis may be the following reasons, need to have a simple to complex one by one investigation, 1, electrical specifications are matching? 2 、 the pump has air intake or air not discharged 3, piping layout is reasonable? 4, check valve installed counter, or check valve did not open, stuck,? This situation is rare, the general novices easily made 5, you missed the judgment? ------------------- most likely the breath, or simply not enough water, the check valve can be judged according to the type of installation position.

Q:Should the pressure gauge be mounted before or after the check valve at the back of the pump?: If the pressure gauge is installed before the check valve, the normal pressure will be displayed only when the pump is running. The pressure value displayed at the pump is not consistent with the actual pressure of the pipe.

Q:Is the check valve the same?: Same。 Call a difference; a thing. You come to our store to have a look.

Q:How to prevent the backflow valve of medium: Among them, the check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface. In order to ensure that the valve can reach the appropriate position of the seat surface at any time, the disc is designed in the hinge mechanism so that the disc has enough swing space to make the disc real and comprehensive contact with the valve seat. The disc can be made of either metal or leather, rubber, or synthetic coverage, depending on performance requirements. The swing check valve is almost completely open and the fluid pressure is almost unimpeded, so the pressure drop through the valve is relatively small. The check valve of the lift check valve is located on the valve seat sealing surface of the valve body. In addition to this valve disc is free to lift, like the rest of the cut-off valve, the fluid pressure valve from the valve seat sealing surface lift, medium return led down to the valve seat, and cut off the flow. Depending on the service conditions, the disc can be of all metal construction or in the form of a rubber pad or rubber ring on the valve frame. The same as the cut-off valve, lift check valve fluid through the channel is narrow, so the check valve by lifting the pressure drop than the swing check valve a little bigger, and swing check valve flow restrictions very little.

Q:What does the check valve "H64" and "H14" mean?: H check valve6 welding connection1 threaded connection4 swing check valveJB/T308-2004< valve type programming method >There should also be sealing surface material code and nominal pressure level

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.

Q:What is the purpose of installing a check valve in the air pipe before the fan?: The fan before the wind pipe installed on the check valve to prevent the fan after the ceased operation outside of the wind because of the air pressure is blown indoors because of the inverse.

Q:What kind of valve does the check valve belong to?: 1. check valves are automatic valves;2., if the valve is cast iron, can be cast iron valves; if the valve is cast steel, can be cast steel valves; of course, can also beIn copper valves, stainless steel valves,,,,,,,3., if used in steam, can belong to the steam valve
