Product Introduction

Bridge type water hammer prevention valveMSP4XBridge type waterproof hammer air valve/Bridge type waterproof hammer exhaust valve/AV821Buffer exhaust valve/Bridge type waterproof hammer air valve/Equipped with buffering device to bridge the water hammer prevention valve/Multi functional bridging water hammer prevention valve/Prevent flow interruption and bridge water hammer air valve/Waterproof Hammer Composite Air ValveMSP4XBridge the water hammer prevention valveIt is mainly composed of a main exhaust valve and a buffer valve group, with the main exhaust valve inlet connected to the buffer valve group. The buffer valve group includes a buffer valve body, a buffer plate, and a throttle hole. The buffer valve body is suspended with a guide shaft, and the buffer plate is fitted on the guide shaft. The water column flows back through the buffer plate and the throttle hole to prevent water column collision and eliminate water hammer.

MSP4XBridge type waterproof hammer air valveIt is a product designed for waterproof hammer pipelines, mainly composed of roller shutter air valves, fast air valves, composite air valves, and buffer plug valves. The bridging type water hammer air valve can prevent the generation of water hammer in the pipeline through rapid exhaust, and suck in air under negative pressure, effectively protecting the operation safety of the pipeline and valves. It is widely used in power plants, power stations, and water companies.

Working Principle:

1. Applied in projects, it can quickly and extensively remove air from pipelines. The double-layer design can effectively prevent impact and has stronger adaptability.

2. When the pipeline is filled with water, the main air valve will seal and the accumulated air will be discharged through the micro air valve. The micro air valve adopts a roller blind sealing structure, which can quickly exhaust and seal, reducing the possibility of blockage by debris, and also has self-cleaning function.

3. Rapid inhalation: When negative pressure is generated inside the pipeline due to unexpected circumstances, it can quickly inhale to protect the balance inside the pipeline and prevent negative pressure.

Product Features:

1. The product has strong adaptability and can be applied in hydraulic pipelines without maintenance.

2. The valve has good sealing performance and is sealed with high-quality nitrile rubber, which will not cause leakage.

3. The valve body of the valve can be coated with resin according to customer requirements to meet drinking water system standards.

4. This product is manufactured in accordance with the requirements of CJ/T217-2005 Municipal Construction standard and has a large exhaust volume.

5. The buffer plug valve at the bottom effectively ensures that the valve will not be impacted by water hammer, allowing it to quickly exhaust under any working conditions.

Technical Specifications:

Nominal diameter (mm):	DN50-DN400
Nominal pressure (MPa):	1.0MPa； 1.6MPa； 2.5MPa
Applicable medium:	Clear water, raw water, drinking water, etc. are below+80 ℃.

Working principle:

1. Preventing flow interruption and bridging water hammer air valve, which relates to an air valve.

2. Solved the problem of insufficient air intake in existing air valves, which can easily lead to water hammer and blockage.

3. The floating ball support plate of the present invention is connected to the inner wall of the valve body. The floating ball support plate has a through-hole, and the floating ball support rod is inserted into the through-hole. The upper end of the floating ball support rod is fixedly installed with a floating ball, and the installation position of the floating ball corresponds to the valve port. The floating ball is used to control the opening and closing of the valve port. The spring support plate is fixedly connected to the inner wall of the valve body, and the lower end of the spring guide rod is fixedly connected to the spring support plate. The upper end of the spring guide rod is fixedly installed on the second valve cover, and the blocking plate is fitted on the spring guide rod. The installation position of the blocking plate corresponds to the second valve port. The upper end of the spring is fixedly connected to the blocking plate, and the lower end of the spring is fixedly connected to the spring support plate. The spring is fitted on Used to control the up and down movement of the blocking plate, which is used to control the opening and closing of the second valve port.

4. Especially suitable for long-distance water pipelines.

Installation location:

1. The highest point of a steep slope.

2. The water column separation point of the pipeline.

3. Install air valves every 400 to 800 meters for long-distance horizontal pipelines.

4. To ensure the effectiveness of use, the air valve must be installed vertically with the pipeline facing upwards.

5. Install a buffer plug valve underneath the air valve.

6. When the pipeline is filled with water, due to the high pressure in the pipeline, when the water flow reaches the opening of the pipeline, the pipeline pressure accumulates at the bottom of the air valve. Without installing a buffer plug valve, excessive water flow pressure can damage the components inside the air valve, leading to phenomena such as air valve leakage and failure to exhaust.
