Vacuum pressure release valve

Introduction of 508 pressure vacuum release valve
TH Ruiguang mechanical pressure vacuum release valve is suitable to be placed on the top of the ash storage. It protects the ash storage from excessive positive and negative pressure when the ash storage intake, exhaust overpressure and abnormal temperature changes. An indispensable protection device for ash storage. The picture is a physical photo of TH Ruiguang pressure relief valve.

Installation and use of vacuum pressure relief valve
1. The pressure relief valve is generally installed on the transformer tank cover or the side wall; 2. For flanged pressure relief valves, flange bases should be provided; 3. For threaded products, see the hole size on the transformer tank cover Installation dimensions; 4. Each product is equipped with a safety helmet, but it is only convenient for users to use in the overall sealing test of the transformer, and it must be removed before operation; the pressure vacuum release valve is used for thermal power generation, building materials, metallurgy The protection device used in the top of the powder and granular storage silos in chemical, chemical and other industries.

The 508 vacuum release valve produced by Gongyi Ruiguang Machinery Factory in Henan can ensure that the user's ash storage (within exceeding the technical performance of the product design) is not affected by excessive positive pressure. The ash storage temperature can be used ≤80 ℃ Is an indispensable protection device for ensuring the safe and effective operation of the ash storage. The pressure vacuum release valve is mainly used to release positive and negative pressure from the top of the storehouse, and can also be used in other occasions with explosion-proof requirements. The pressure release valve is generally installed on the top of the storage tank. When the internal pressure of the storage tank exceeds the set value, the positive pressure valve plate of the pressure release valve automatically opens to release the excessive pressure in the storage tank; When the internal negative pressure of the storage tank exceeds the set value The negative pressure valve plate of the pressure release valve opens automatically to supply fresh air to the storehouse, thereby protecting the safe operation of the storehouse.
