Working principle of stainless steel automatic exhaust valve

When there is gas overflow in the system, because the gas density is smaller than water, the bubbles will float up to the top of the inner wall of the pipe. Driven by water, the gas will climb up along the pipe and finally gather at the high point of the system. The stainless steel automatic exhaust valve is generally installed at the high point of the system. When the gas enters the valve chamber of the stainless steel automatic exhaust valve and gathers at the top of the stainless steel automatic exhaust valve, the pressure will rise with the increase of the gas in the valve, When the gas pressure is greater than the system pressure, the gas will make the water level in the cavity drop, and the buoy will drop with the water level, and open the exhaust port; After the gas is exhausted, the water level rises, and the buoy also rises, and the exhaust port is closed. In the same way, when negative pressure is generated in the system, the water level in the valve chamber of the stainless steel automatic exhaust valve drops and the exhaust port opens. Because the external atmospheric pressure is greater than the system pressure at this time, the atmosphere will enter the system through the exhaust port to prevent the harm of negative pressure. If the bonnet on the valve body of the stainless steel automatic exhaust valve is tightened, the stainless steel automatic exhaust valve will stop venting. Generally, the bonnet should be open. The stainless steel automatic exhaust valve can also be used with the block valve to facilitate the maintenance of the exhaust valve

Features of stainless steel automatic exhaust valve

1. Reliable performance: The exhaust mechanism of the stainless steel automatic exhaust valve is very reliable. Each valve has passed the exhaust test and pressure seal test before leaving the factory.

2. Convenient maintenance: A block valve (optional) is installed in front of the stainless steel automatic exhaust valve. The block valve allows convenient removal of the exhaust valve from the system for maintenance, while the water in the system will not flow out, so it is not necessary to drain or shut down the system.

3. Only exhaust without drainage. The steam and water separation design adopts special structure to ensure no water leakage during exhaust.

4. The parts are made of stainless steel SS304, which is not easy to corrode and durable, and suitable for high temperature of 200 ℃.

5. The high polymer floating ball has light weight, high temperature resistance, corrosion resistance and good exhaust effect.

Installation and precautions of stainless steel automatic exhaust valve

1. The stainless steel automatic exhaust valve must be installed vertically, that is, the buoy inside must be kept in a vertical state to avoid affecting the exhaust;

2. When installing the stainless steel automatic exhaust valve, it should be installed together with the block valve, so that when the stainless steel automatic exhaust valve needs to be removed for maintenance, it can ensure that the system is sealed and water will not flow out;

3. The stainless steel automatic exhaust valve is generally installed at the high point of the system, which is conducive to improving the exhaust efficiency;

4. Too low system pressure is not only harmful to the exhaust of stainless steel automatic exhaust valve, but also increases the possibility of water leakage;

5. The working medium should be clean to avoid water leakage caused by impurities remaining on the sealing surface;

6. The thicker or sticky working medium will attach to the buoy or floating ball of the stainless steel automatic exhaust valve. Solidification or drying on its surface will affect the normal upward and downward movement of the buoy or floating ball, and even affect the exhaust and sealing of the exhaust valve.
