- Q:How to install fire fighting pipe and flue fire check valve?
- 4, the installation of flue should each layer as bearing, bearing steel 2 root diameter over 14mm?.5, after the installation of the flue, in each flue check valve of the reserved installation of fire type flue check valve, with special glue mixing cement, coated with a check valve installed in the valve hole edge, and then back to the reservation in check at.6, the construction should be reserved at all levels of the hole, covered with a cover plate, to ensure safety in construction, to prevent construction waste fall into the flue.
- Q:Swing check valve can prevent any sewer defection
- Sure。Swing 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 function of the small check valve on the deep well pump?
- This valve is to stop the pump when the intake, through the intake of water to cut off the backflow, to prevent water from being returned to empty, the air can not enter the valve above the part of the water pipe, rest assured
- Q:How can the fast closing noise check valve prevent water hammer?
- Biaoguan valve that once the pump stopped, check valve spool in the spring or other auxiliary device for double end under the action of force balance in advance to the closed position, can greatly reduce the amount of water and initial water reflux falling height, water hammer force is calculated by gravity superposition, to reduce the amount of water is equal to the reduced gravity, but fell short height reduces the inertia time is relatively reduced speed, and can prevent the formation of destructive or reduce water hammer water hammer.
- Q:The check valve on the air pipe is installed in front of the fan and is there any difference in the back (direction is correct)?
- Installed in front of the wind blowing, the top open check valveIt is difficult to install the check valve, which is installed on the rear by the force of air suction.
- Q:Does the check valve damage affect the flow rate?
- Ball check valve will not affect the flow, such as the clip type check valve once damaged, it will affect the flow.
- Q:What is the function of the check valve installed in the water meter before entering the residential water?
- Preventing water backflow is also considered from the point of view of water safety.
- Q:Check valve can not stop water, how to solve?
- Valve is broken, change one, my family is like this
- Q:How to control the common flue return and smoke return?
- Regular developers submitted, the flue port has installed a check valve for the owners,It is usually closed, and only when the smoke exhauster exhaust smoke will make the check valve open.In addition to the function of the check valve to prevent flue gas recirculation, each hood has a check valve. If you look carefully, you will see that there is a two piece fan at the exit of the smoke machine, which can only be opened in one direction. Its function is the same as the check valve in the flue.Therefore, in fact, there are two soot hoods to prevent smoke from building. Even the first one is broken, and the second are equally effective.Therefore, you can find the reason, whether the check valve two are all broken.
- Q:How many kinds of structure are there in the check valve?
- 3 butterfly check valve structure similar to butterfly valve, its structure is simple, flow resistance is small, water hammer pressure is smaller;4, diaphragm type check valve has a variety of forms, are used as the opening and closing the diaphragm, due to its good waterproof performance, simple structure, low cost, rapid development in recent years, but the use of diaphragm valve temperature and pressure by the diaphragm material limited;
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.
