Copper automatic exhaust valve production

Copper automatic exhaust valvesketch:

Copper automatic exhaust valveThe design takes into account all known adverse factors and has excellent performance: whether the system is just running with water (there is a large amount of gas discharged when the system is just running) or when the system pressure is too high and requires moderate drainage and pressure relief, it can operate reliably.

Working principle of automatic exhaust valve:
When there is air in the system, the gas accumulates at the upper part of the exhaust valve, and the accumulation of bubbles inside the body causes the floating ball to drop with the water level, thus opening the exhaust piston; After the gas is exhausted, the water level rises and the float also rises, closing the exhaust piston. If the valve cap on the side of the valve body is tightened, the exhaust valve will stop exhausting. Normally, the valve cap should be in the open state.

Technical specifications for automatic exhaust valves:

1. Nominal pressure: 1.6MPa

2. Working medium: water, oil, gas

3. Working temperature: 0 ℃ ≤ t ≤ 100 ℃

4. Pipe threads comply with ISO 228 standard

Features of automatic exhaust valve:

1. Reliable performance. The material used for the emission device is PK-EP. Compared to all known synthetic materials, PK-EP has excellent performance and reliability. PK-EP can withstand high temperatures (much higher than the working temperature of exhaust valves). The O-ring uses optimized material EPDM to ensure good elasticity and operational reliability even at high temperatures. The internal spring of the exhaust valve core is made of special materials and nickel plated stainless steel to prevent oxidation (which may affect the movement of the core); The exhaust mechanism of the exhaust valve is very reliable, and each valve undergoes exhaust and pressure sealing tests before leaving the factory. Each individual component is cast with high precision, resulting in an assembly of *.

2. Easy maintenance. The automatic exhaust system is equipped with an H18 blocking valve, which allows for easy removal of the exhaust valve from the system for maintenance without the need to drain the system due to water leakage.

3. Only exhaust, not drain. The design of the steam and water separation disc adopts a special structure to ensure that there is no drainage during exhaust.

4. As long as there is pressure in the system, the exhaust valve will continuously exhaust.

Installation and usage instructions for automatic exhaust valve:

1. The automatic exhaust valve is installed vertically, and the vertical pipeline must be installed at the high end, while the horizontal pipeline must be installed at the end. 2. The exhaust valve must be installed vertically, ensuring that the float inside the valve body is in a vertical position and cannot be installed horizontally or upside down;
3. After installing the automatic exhaust valve, it is necessary to loosen the small nut on the upper end to ensure smooth gas discharge.
4. For ease of maintenance, exhaust valves are generally used together with block valves.
5. In the use of automatic exhaust valves, if leakage occurs due to blockage caused by dirt, tighten the small nut and release the exhaust valve for cleaning. After cleaning, it can be reinstalled and used again.
