Special pressure valve precipitator dust explosion-proof special pressure valve product parameters: 1, the overall safety valve: Using high strength steel; surface paint color (beige / silver) 2, flange connection: use rust-proof stainless steel bolts 3, rain hat; the use of high strength steel, the surface paint (beige / silver) play an anti-rain effect. 4, the maximum air volume: 9.000m3 / h 5, the maximum preset negative value: - 0.002 bar; maximum pressure + 0.05 bar 6, Product summary: Lightweight design, reducing the overall size, easy handling, high resistance to pressure interference easy to install, maintain and fast. Product Description: Pressure-proof valve body: carbon steel surface spray (gray, yellow) valve plate: carbon steel, black special sealed connection: clamp connections, with a ring cover: carbon dust explosion-proof special pressure valve Installation: Pressure-proof valve play a security role in the system. When the system pressure exceeds a predetermined value, the safety valve open Ting, the system part of the gas into the atmosphere, so that the system pressure does not exceed the allowable value, in order to ensure that the system pressure is too high due to an accident does not occur. Also known as a safety valve relief. Several typical structure is illustrated as a safety valve. Figure A is a piston valve, the valve is a flat. Air pressure acting on the piston A, when the pressure exceeds a safe value determined by the spring force, piston A is top open, a portion of the compressed air that is discharged into the atmosphere from the valve port; when the air pressure falls below the safety value, the drive spring piston down, closes the valve port. Explosion pressure valve when the pressure inside the device to work under pressure within a certain range, the internal medium acting on the valve on top of the force is less than the load applied to the valve body above the force, the difference between the two constitutes a valve and valve seat sealing force, so that the valve seat is pressed against the media, the device can not be discharged. When the pressure inside the device exceeds the pressure of work and reach safety valve opening pressure, the internal role of the media in trouble flap above loading mechanism force is greater than the force exerted on it, and then leave the valve seat and valve open, equipment i.e. within the medium is discharged through the valve seat. (1) When a gas container, liquid two-phase materials, the valve should not be installed in the gas phase portion. (2) relief valve is mainly used for flammable liquids, should be connected to the outlet valve of the tank accident. When flammable liquid fuel for high temperature, then the receiving container must have protection facilities. (3) you can place the vent valve, but the vent must be one meter higher than the operating personnel, and fire can not occur within fifteen meters. If the vent is installed indoors must lead to the roof and the roof should be higher than about 2 two meters. (4) At the entrance there are some safety valve block valve, it should be kept normally open state, isolation valves should be in a normally open state, and be sealed with lead, to prevent errors.
