Product Introduction

Waterproof hammer exhaust valveFOXWaterproof Hammer Air ValveFOX-2Waterproof hammer type air valve/Waterproof hammer type exhaust valveIt is used on pipelines that are prone to sudden pressure and large impact during water supply, to prevent excessive water spray during exhaust and effectively reduce the impact on the interior of the exhaust valve, thereby extending the service life of the exhaust valve. The main cause of water hammer is the presence of air in the water pipes. When the air column suddenly drops in pressure, it expands, pushing the water column to move. This causes air to push water, and water to push air, resulting in water hammer and significant destructive force. Especially the first timeTo test the water, it is necessary to exhaust the air before stopping the water supply.

Operating principle:

It can be seen that there are many small holes at the top of the valve. The floating ball support plate is connected to the inner wall of the valve body, and there are through holes on the floating ball support plate. The floating ball support rod is inserted into the through holes. The upper end of the floating ball support rod is fixedly installed with a floating ball, and the installation position of the floating ball is corresponding 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 is corresponding to the second valve port. The upper end of the spring is fixedly connected to the blocking plate, and the lower On the rod, the spring is 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.

Installation requirements:

1. Before installation, please check and remove any debris inside the main body.

2. Install a gate valve in front of the exhaust valve for future installation and maintenance.

3. If the exhaust valve is installed in a shaded well, there should be sufficient space to accommodate technical personnel for adjustment and maintenance work.

4. If the waterproof hammer type exhaust valve is installed outdoors, please pay attention to the insulation of the valve to prevent water from freezing or cracking the valve.

5. If the pipeline where the exhaust valve is located frequently loses water supply, it is recommended to install a buffer valve in front of the exhaust valve.
