- Q:The principle of the check valve
- The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).
- Q:How does the check valve work?
- Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent the media back flow valve, also known as check valve, Dan Xiangfa, counter flow valve and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the opposite direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow.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.
- Q:Why should the check pipe be added to the chilled water pipe of the air conditioning unit?
- The air conditioning unit you refer to the indoor air terminal or refrigeration unit (the air conditioning form of this with you to say you take the form of water source heat pump and board for the air conditioning unit, you said that is placed in the interior of the water ring pump unit). The air conditioning unit when you refer to the refrigeration unit, for example by pressing in the form, you will need to pump and the unit set between the check valve to prevent the pump start and stop when the air conditioning water poured into the pump, the damage of equipment; air conditioning units when you refer to (e.g. water loop heat pump indoor unit) in the room, there is no need to set the check valve, usually in the import chilled water is arranged on the electric valve two, flow switch, exhaust valve and so on can.
- Q:What are the specifications of the DN200 check valve?
- DN200 is a specification.The principle of the check valve, the check valve, the opening and closing parts, depend on the flow of the medium and the power to open or close on its own, so as to prevent the backflow of the medium, called the check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, 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. A check valve is a valve that automatically prevents the flow of fluid. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the exit side, the valve automatically closes under the influence of fluid pressure, gravity and other factors to prevent fluid flow backwards.
- Q:Does the regulator have a check action? If yes, can I use it as a check valve?
- No, it can only be used for regulating pressure. It can not replace the check valve.
- Q:What does the number 16 on the check valve mean?
- This is the pressure level of the valve, which represents 16Kg, which is used for piping pressure less than this pressure.
- Q:What is the reason that the check valve does not stop water?
- 7, when installing check valve, should pay special attention to medium flow direction, should make medium normal flow direction and the direction of the arrow on the valve body is consistent, otherwise it will cut off the normal flow of media. Valve should be installed at the bottom of the pump suction pipe.The general formula 8, lift check valve should be installed in horizontal pipe, vertical lift check valve and bottom valve is usually installed in a vertical pipe on the road, and the bottom-up flow of media.9, the check valve closes, will produce water hammer in pipeline pressure, will lead to serious damage to the valve and piping or equipment, especially for the big pipe or high pressure pipeline, it should pay attention to those who use check valve.
- Q:What's the W in the check valve H44W?
- First, the meaning of "W" in check valve H44W:The H44W in the check valve W represents the seat of the check valve, and the sealing surface or lining material is the body sealTwo, check valve H44W model significanceLetter H: stands for check valveFirst number 4: the driving mode is the positive gearSecond numbers 4: the connection form is the flange
- Q:What does the check valve "h61h-25 H" mean?
- From the model analysis, for the cast steel welding lift check valve, it depends on your valve is not it
- Q:Can the check valve be used on the steam pipe?
- The check valve can be used on the steam pipe, but only the right material.General steam pressure WCB, temperature and pressure with the then high chromium molybdenum steel. The inside of the valve should be taken into account, depending on the pressure difference.
