508 pressure vacuum release valve

508 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 pressures when the ash storage intake, exhaust pressure and abnormal temperature changes. An essential protection device.

Installation and use of vacuum pressure relief valve
1. The force release valve is generally installed on the transformer tank cover or the side wall; 2. For pressure relief valves with flange structure, the flange base should be configured; 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.
508 pressure vacuum release valve can ensure that the user's ash storage (without exceeding the technical performance of the product design) is not affected by excessive positive pressure. The ash storage temperature can be used ≤80 ° C, which is your guarantee ash storage A necessary protective device for safe and effective operation. 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.

Gongyi Fucheng Machinery Factory is the earliest professional manufacturer of material-sealed pump equipment. Based on the introduction of foreign advanced technology, our factory has developed a new type of low-pressure pneumatic force based on the introduction of foreign advanced technologies for various problems in different types of pneumatic conveying equipment in China and cooperation with the Building Materials Institute. Conveying material sealing pump, widely used in electric ash removal, cement homogenization and storage, various powder materials, high efficiency and low consumption, fully enclosed, no pollution, no maintenance, air source can choose Roots fan, compressed air .

After years of development, our factory has formed three complete product systems: low-pressure pneumatic conveying equipment, mechanical conveying equipment and ash storage equipment, which are widely used in many fields such as cement, electric power, building materials, metallurgy, and chemical industry. Our factory has always adhered to the principle of quality first and credit first, and established a set of one-stop quality management system from parts processing to the whole factory's delivery, and implemented computer-aided system optimization design for all products.
