Q:Is the check valve installed at the inlet or outlet of the pump? Why?
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:What is the function of the ventilator's check valve?
When the soot exhauster stops working, the one-way valve plate is automatically closed under the action of gravity, and the fume passage is isolated from the common flueThe smoke in the flue doesn't flow back in.
Q:What's the difference between check valves and non-return valves?
2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.3, swing type: liquid through the valve body, relying on the pressure to open the side of the rotating valve flap,After the pressure is lost, the disc depends on its back weight and the reverse liquid pressure seals the disc.
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:The role of the clip lift check valve
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:Butterfly micro stop type check valve HH46XP-10Q, what does the letter mean?
Do not know what you say is the manufacturer of valves, in general, many models are manufacturers themselves according to the specifications of their products set.
Q:What is the reason that the check valve does not stop water?
1, the valve at both ends of the road must be blocked, there is dry ventilated room. Such as long-term storage, should always check rust corrosion.2, the valve should be cleaned before installation and eliminate the defects during transportation.3, the installation must be carefully checked on the valve signs and nameplates are in line with the use of requirements.
Q:The difference between check valve and check valve
The same thing, called, is based on the difference in the use of the actionFor example, overflow valve and safety valve, back pressure valve, are the same thing, are in the one-way valve behind the increase of back pressure spring
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:I also calculate each pump check valve and gate valve?
The pump adapter itself does not include the gate valve and the check valve! Only when a group called pump adapter will include adapter, gate valve and check valve!If the pump adapter in the list of units for the group then all included and work content in clear note on the contents.If you do it alone, write out no items!
Yue,located in Ducun Industrial Park, Linhu Town, Wuzhong District, Suzhou, mainly produces valves. Our company is equipped with one scale automatic static coating line, two assembly testing lines, many sets of semi-automatic assembly testing equipment as well as processing equipment such as 5m,3m and 2m vertical lathes, 4m and 2m milling machines and boring machines.
