- Q:Installation position of air pipe check valve
- If you are not in a hurry, leaving QQ, etc. I reply to your husband for this afternoon, he is very professional.
- 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:The working principle of the vacuum check valve
- Check valve inlet pressure when using open valve, inlet pressure is less than the pressure loss or outlet pressure when the outlet fluid backflow, the valve plate is closed, vacuum check valve principle is the same
- 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
- Q:How can the lift vertical check valve be distinguished from the lift horizontal check valve?
- 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 valve for the straight through, the above non-return valve can be divided into connection, flange and welding of three lift check valve and stop valve structure similar to the thread in the form of connection, the valve in a line along the channel for the lifting movement, reliable action, but the fluid resistance is large. Small in diameter for the occasion. Lift check valve can be divided into straight and vertical two kinds. Straight through lift check valve can only be installed in horizontal pipe, vertical lift check valve is usually installed in vertical pipe. You can see the picture in Baidu's picture
- Q:Why is the intelligent water meter equipped with a check valve, still can not prevent the water meter idling?
- 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:Is the flue check valve the same as the flue check valve? What's the difference?
- The flue check valve is not the same as the flue check valve;Flue check valve: a valve that is used at the joint of the hood, flue pipe and flue. Mainly to prevent the role of soot intrusion. The smoke in the apartment building is a public flue, and sometimes the food is always wafted from upstairs to downstairs when cooking, usually from the flue. This check valve can have a certain extent to prevent soot from the role of intrusion, but after all, it is difficult to completely sealed, so the food can not completely prevent the taste of isolation.Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve.
- Q:Is the check valve in or behind the gate valve? Why?
- Pump outlet, check valve, gate valve.Gate valve plays a regulatory role, is the main pipe. Such a sequence can ensure that the water flow during power failure does not cause damage to the gate valve.
- Q:Method for mounting back check valve of pump
- Check valves shall be installed on the vertical pipe. Select a model, such as a slow closing check valve (water hammer) or a spring check valve.
- Q:With no negative pressure water supply, the pump is equipped with a check valve, the construction ring network also needs to install check valve?
- With no negative pressure water supply, the pump is equipped with a check valve, the construction ring network also needs to install a check valve, or else the water pump may enter the ring network.
