A9H-Q explosion-proof wave valve
- A9H-Q防爆波阀 Category: A9H-Q explosion-proof wave valve
- ￥ 面议 Price: ￥ Negotiable
The A9H-Q explosion-proof wave valve was developed in accordance with the technical requirements of the Civil Defense Engineering Tactical and Technical Requirements and the Air Defense Basement Design Regulations of the Ministry of Construction. This product is a safety valve that can eliminate and block water hammer shock waves. It is also a special equipment for pipeline protection of civil air defense engineering. The successful development of this product has filled the domestic blank. The valve has good performance and easy installation, and can be applied to civil defense engineering pipeline protection with six and five resistances. The valve has been listed in the standard map of civil air defense basement construction by the Ministry of Construction, and is used throughout the country.
This valve is a kind of protective equipment installed on the water supply and heating pipes of civil air defense engineering. The valve is normally open. Wartime relies on a combination of blocking and eliminating. It can prevent the shock wave from entering the project along the pipeline, so as to eliminate the destructive shock wave, protect the normal operation of the system and facilities and protect the safety, and ensure the safety of indoor personnel and equipment.
Two: A9H-Q explosion - proof wave valve working principle:
Under normal working pressure conditions, the spring-supported valve plate is in the open position, which allows the medium in the pipeline to pass through normally. In wartime, it passes through the tank storage tank or ruptured pipeline. The pressure in front of the valve plate suddenly increases, and a strong pressure difference is formed before and after the valve plate. Under the action of the high pressure chamber, the spring is compressed, the valve plate quickly reaches the closed position, and the shock wave is blocked out of the valve plate, which resolves the destructive force of the shock wave. Protective and safe by blocking and defusing. After the shock wave has passed, the valve plate is still in the open position and the pipeline is restored to normal working conditions.

Five, the main size parameters of A9H-Q explosion - proof wave valve :
Seven, A9H-Q explosion - proof wave valve installation and maintenance:
1: Check whether the main valve valve is flexible and whether the connecting parts are loose before installation. 2: When a large product is installed in a trench, the bottom should be equipped with a bracket. 3: During use, the valve should be checked frequently, the drain hole plug should be opened, and the water stored in the anechoic chamber should be excluded. 4: The main valve should be inspected and maintained once every two years. Remove valve impurities and scale on the sealing surface to facilitate normal valve operation. 5: If the main valve spring is found to be seriously rusted, it should be replaced.
