Abstract
The utility model discloses a gas-solid isolating valve, which comprises a right valve body, a left valve body and a filtering device arranged between the right valve body and the left valve body. The filtering device comprises a first porous plate, a second porous plate and a filtering plate. The filtering plate is arranged between the first porous plate and the second porous plate. According to the utility model, the filtering plate is sandwiched between the two porous plates. Therefore, even if the pressure difference between two ends of the valve body is large, solid powder particles are effectively prevented from entering the air pipeline of the valve under the running environment of gas-solid two-phase flow. Therefore, the safe operation of an inlet valve group is ensured.
Description
Technical field
The utility model relates to the gas-solid disconnecting valve.
Background technology
Pneumatic Conveying Technology belongs to Dual-Phrase Distribution of Gas olid, in the bulk material transportation art, has a extensive future.Air-transport system mainly is made up of source of the gas and purification plant, supply air line and annex, storehouse pump and various valve, conveying pipeline road and annex, storage warehouse and transloading equipment and instrument and electrical control equipment etc.The mass transport technological process is: bulk material gets into the storehouse pump from hopper, in the pump of storehouse, fully mixes with pressurized air, and the Dual-Phrase Distribution of Gas olid after the fluidization is through the storage warehouse of airtight conveying pipeline entering far-end.Two phase flow carries out gas solid separation at the storage warehouse place, and pressure gas passes through bag dust collector and filters emptying, and solid granule transloading equipment temporary at storage warehouse or that pass through under the material storehouse is transported outward.
In the air-transport system, pressurized air is the power source of total system.And the air inlet valve group is to distribute, optimize the execution unit of power air.And the non-return valve in the air inlet valve group is a critical valves, and its effect is when the difference of pressure variation at valve two ends or reverse, stops the fluid that contains bulk material to get into the valve other end.In the strength delivery application engineering of present bulk material, the function of non-return valve does not all have to ensure that the non-return valve that improves effect is not arranged on the market targetedly yet.Adopt many non-return valves to have in the engineering: the lift-type boiler check valve of the flapper valve of action of gravity, initial tension of spring, rubber seal tapered valve etc.In the working environment of Dual-Phrase Distribution of Gas olid; When the difference of pressure at valve two ends has bigger variation; Above valve all can not effectively stop solid powder/particle materials flow body to get in valve body and the admission line; Then can cause the wearing and tearing of non-return valve spool and sealing surface, influence the quality and the execution action that hinders Pneumatic valve of airline air, finally cause putting into operation automatically of air-transport system to stop.
The utility model content
The purpose of the utility model is to provide the gas-solid disconnecting valve; Can effectively solve present non-return valve when the bigger variation of valve pressure at two ends difference; Can not effectively stop solid powder/particle materials flow body to get in valve body and the admission line, cause the problem that puts into operation automatically and stop of air-transport system.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: the gas-solid disconnecting valve; Comprise right valve barrel, left valve barrel, filtering installation; Said filtering installation is arranged between right valve barrel and the left valve barrel, and said filtering installation comprises first breaker plate, second breaker plate, screen plate, and said screen plate is arranged between first breaker plate and second breaker plate.
Preferably, the left side of said right valve barrel has left groove, and the right side of said left valve barrel has right groove, and said left groove and right groove are formed mounting groove, and said filtering installation is arranged in the mounting groove; Firm being arranged between two valve bodies of filtering installation ability that is can be born bigger difference of pressure.
Preferably, be provided with packing seal between said filtering installation and the left groove, also be provided with packing seal between said filtering installation and the right groove; Guarantee that further solid powder/particle can not get into admission line.
Preferably, also comprise screw, said left valve barrel, filtering installation, right valve barrel connect through screw retention; Adopt screw retention replacing filtering installation for convenience detach.
Preferably, said first breaker plate, screen plate, second breaker plate connect through bolt; The employing bolt is simple and reliable.
Compared with prior art; The utility model has the advantages that: screen plate is clipped between the two porous plates, in the running environment of Dual-Phrase Distribution of Gas olid, even there is very big difference of pressure at the valve body two ends; Also can stop the solid powder/particle material to get into airline by actv., guarantee the safe operation of air inlet valve group.
