Description
Technical field
The present invention relates to a kind of piston valve, more particularly, to a kind of sack cleaner piston valve.
Background technology
Sack cleaner is a kind of dry type dust filtration device.It is applied to tiny, dry, the non-fiber dust of trapping.
Filter bag is using the filter cloth or nonwoven felt of weaving into being carried out to dusty gas using the filtration of fabric
Filter, after dusty gas enters sack cleaner, granule is big, heavy dust, as the effect of gravity is sunk
Lower, fall into ash bucket, when by filtrate, dust obtains gas by detention to the gas containing relatively fine dust
To purification, it is a kind of high-effective dust-removing equipment.
Sack cleaner operation principle is：Dusty gas is entered and is filtered by ash bucket (or bottom spaciousness open type flange)
Room, falls directly into ash bucket or ash silo compared with coarse granule, and dust gas Jing sock filtrations, dust are detained to filter bag surface,
Net gas Jing bag mouth enters air to air-purifying chamber, by blower fan, when the dust on filter bag surface is continuously increased, causes equipment to hinder
When power rises to setting value, the time relay (or elementary errors pressure controller) output signal, program control instrument are started working,
Unbalanced pulse valve, makes compressed air carry out jetting deashing to filter bag by spout, filter bag is expanded suddenly one by one,
In the presence of back draught, the dust for investing filter bag surface departs from rapidly filter bag and falls in ash bucket (or ash silo), powder
Dirt is discharged by unloading valve, and after whole filter-bag blowing deashings terminate, cleaner unit recovers normal work
Piston valve is an important component part of sack cleaner, at present, the piston of the piston valve commonly used on market
Can be that slidably, in installation process, the careless slightly phenomenon that piston landing will occur, scrapes in valve body
Trace can affect piston face quality, so as to affect valve opening and closing performance, this situation occur in installation process aloft such as
Security incident can more likely occur.
The content of the invention
The purpose of the present invention is exactly to provide a kind of installation simple side to overcome the defect of above-mentioned prior art presence
Just a kind of, the high sack cleaner piston valve of reliability.

There is leakage between valve gap 6 and valve body 8, piston 11 is arranged in valve body 8, and 8 bottom of valve body is provided with retainer ring
16, below valve body 8, inner side is provided with locating shim 12, and the locating shim 12 is installed by circlip for hole 13
In valve body 8, on the one hand as piston 11 can be slidably, in installation process slightly in valve body 8
There is the phenomenon that the landing of piston 11 will occur accidentally, scratch can affect 11 surface quality of piston, so as to affect valve
, such as aloft there is this situation in installation process and security incident, locating shim can more likely occur in start-stop performance
12 effect is that can effectively prevent piston 11 from sliding out valve body 8, but while and just not affect valve
Often open and close, bottom is equipped with circlip for hole 13, on the other hand easy disassembly can help the weldering of injection tube 15
Connect, valve body 8 is arranged on gas bag 17, by injection tube 15 from bottom mounting apertures insertion locating shim 12,
As long as ensureing the concentricity of injection tube 15 and installing hole by directly welding after adjusting height, greatly reduce and add
Work difficulty.
Valve body 8 includes top flange 81, the multiple legs 83 of middle chamber 82 and bottom and the ring 16 that is connected,
Flange is connected with valve gap 6, and the plurality of leg 83 is connected ring 16, be increased while injection amount is ensured
The intensity of valve body 8, it is to avoid collide with phenomenon so as to cause valve body 8 to deform in transport and installation process, cause
Piston 11 cannot normal mounting or generation jam phenomenon.
Locating shim 12 is located at below piston 11, and locating shim 12 is removed with pocket type in annular shape, its annular diameters
15 external diameter of injection tube of dirt device matches, and external diameter is matched with the internal diameter of valve body 8, and locating shim 12 is provided with gas
Body through hole, contacts formation sealing through locating shim 12 at the top of injection tube 15 with piston 11；During work, pocket type
Gas in the gas bag 17 of cleaner unit is entered in valve body 8 by the gas via-hole on locating shim 12, promotes piston
11 move upwards, and gas is blown out from injection tube 15.
8 bottom of valve body is provided with hole slot, and circlip for hole 13 is arranged in the hole slot, for locating shim 12 is fixed
Position is in valve body 8.
