- Q: The working principle and structure description of the mute check valve
- 1, when the medium according to the provisions of the direction of flow, the valve by the media force, is open; the medium back, due to weight and disc valve by the medium reverse force, so that the sealing surface of the valve flap and valve seat sealing and closed, to prevent the media counter to.2, the body and valve sealing surface using stainless steel surfacing.3, the length of the valve according to the provisions of GB12221-1989, flange connection size according to the provisions of JB/T79-1994.
- Q: Which kind of steam check valve is good?
- The shell material 13, ball valve can be made of stainless steel, sealed hollow sphere parts can be coated PTFE engineering plastics, can also be applied in the pipeline so general corrosive medium, the temperature at -101--150 DEG C, the nominal pressure is less than 4.0MPa, nominal in the range of 200 - 1200;14, for non compressible fluid check valve selection, first of all the required closing speed evaluation, the second step is to select the type of check valve that may meet the required closing speed;15, can be used for check valve selection of fluid compression can be selected according to the similar method can not check valves for compressed fluid flow, if the medium category is used for large, compressible fluid check valve can be used for a slow device, if not continuous medium flow fast to stop and start such as, the outlet of the compressor, use the lift check valves;16 the check valve shall determine the size of the response. The valve supplier must provide the data data of the selected size so that the valve size of the valve opening at a given flow rate can be found;17, for the following DN50mm high and low pressure check valve, should choose vertical lift check valve and straight through lift check valve;18. For DN50mm low pressure check valves, butterfly check valves, vertical lift check valves and diaphragm check valves shall be used;19, for DN greater than 50mm, less than 600mm high pressure check valve, it is better to use swing check valve;20, for DN greater than 200mm, less than 1200mm of medium and low pressure check valve, should choose no wear ball check valve;21, for DN greater than 50mm, less than 2000mm low pressure check valve, Iraq butterfly butterfly check valve and diaphragm check valve;22, for the closure of water shock or small impact of the pipeline, it is appropriate to use the slow closed swing check valve, butterfly butterfly valve closed
- Q: What kind of check valve is used in the sewage pump of sewage treatment plant?
- Selection of check valve for pump outlet check valveGeneral pump station project, for the pump outlet check valve, the following principles should be observed;The outlet check valve shall be used when the diameter of the outlet pipe of the pump is smaller, that is, DN50mmThe pipeline of the pump outlet pipe diameter DN is larger than 50mm, should be used in swing check valves can be installed horizontally or vertically. Swing check valve to rotate around the shaft, the fluid resistance is generally less than the lift check valve, which applies to the larger diameter of the occasion, the installation location restrictions, usually installed in horizontal pipelines, it applies with large caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves for medium and medium duty applications. Large diameter pipeline using single swing check valve, in order to reduce the water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double valve swing check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a fast check valve. Multi disc swing check valve is suitable for large diameter pipeline
- Q: Why can't parallel check valve be installed firmly?Anonymous browsing | 51 times
- The vertical installation is easy to cause the valve core of the check valve to clamp off or fall off, and lose the function of checking back. The direction of the check valve is restricted seriously from any direction of the medium
- Q: Should the kitchen check be mounted on the wall or on the hood?
- It should be mounted on the wall. If you have more questions, click ID.
- 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: Is the flue check valve the same as the flue check valve? What's the difference?
- 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.
- Q: How to install fire fighting pipe and flue fire check valve?
- 1, vertical transport, the flue should take protective measures, and must be two lifting.2. Locate the center line of the flue position. In the reserved hole, draw down four vertical central lines from the roof, and draw 2 orthogonal central lines on the floor plane.3, the flue to the scene, the first flue hanging to the roof, surrounded by the center line of pop in the flue, and the flue of the reserved hole slowly down the electric hoist, from top to bottom layer installed flue in place, the center line correction. The center line of the flue and the center line of the reserved hole should be less than 1cm, the deviation of the centerline of the upper and lower flue is not greater than 1cm, and each flue must be guaranteed vertically and vertically.
- 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: How can the fast closing noise check valve prevent water hammer?
- It is recommended to see the principle of water hammer in fluid mechanics and the structure and principle of the check valve. These are not a few words to talk about, you can understand, and the important thing is to study your own! Only in this way can I really understand.
