The function and principle of the latest automatic exhaust valve

During the operation of heating systems and HVAC systems, many adverse effects of gases (such as hydrogen, oxygen, etc.) released during the heating of water will damage the system and reduce the thermal effects. If these gases are not drained in time, many undesirable effects will occur. as a result of. Such as: corrosion caused by oxidation; the formation of airbags in the radiator; hot water circulation is not unimpeded and unbalanced, so that some radiators do not heat locally; the noise of pipelines running with air; the vortex phenomenon of circulating pumps. This shows the important role of the use of automatic exhaust valve.

The new automatic exhaust valve design takes into account all the known unfavorable factors (such as impurities in the water, oil, suspended solids, etc., turbulence in the valve during discharge, vibration of the pipes and equipment connected to the exhaust valve, etc.). ) Excellent performance: Whether the system is just running with water (when the system is just running, there is a lot of gas discharge) or it can be reliably operated when the system pressure is too high and proper drainage pressure is needed.

First, the characteristics of the exhaust valve:

1. Reliable performance. Exhaust valve exhaust mechanism is very reliable, before leaving the factory each valve through the exhaust test and pressure seal experiment. Individual components are cast with high precision for perfect assembly.

2. Easy to maintain. The automatic exhaust is equipped with a blocking valve. The blocking valve allows the exhaust valve to be easily removed from the system for maintenance. Water in the system does not flow out, so it is not necessary to empty the system.

3. Only exhaust, no drainage. Steam and water separation discs are designed with a special structure to ensure that they do not drain during exhaust.

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

Second, the main purpose:

Automatic exhaust valve for: independent heating system; central heating system; floor radiant heating system; solar heating system; heat pump system; central air conditioning; heating boilers, etc. Third, automatic exhaust valve working principle When the system has air, The gas accumulates in the upper part of the exhaust valve. The accumulation of air bubbles in the body causes the float to fall with the water level, so the exhaust piston is opened. When the gas is exhausted, the water level rises and the float rises, closing the exhaust piston. If the bonnet on the side of the valve body is tightened, the exhaust valve will stop exhausting. In general, the bonnet should be open.
