Abstract
The utility model relates to a pneumatic four-way valve, which comprises a valve body. The valve body comprises two parts of a front valve body and a back valve body; a muffler is arranged in the middle of the front valve body, simple pneumatic cut-off valves are arranged symmetrically on the both sides, the air outlet of the simple pneumatic cut-off valves is communicated with the muffler; a shuttle valve is arranged in the back valve body. The utility model is widely used in the air source purification system of air compressors and has the advantages of small size, simple structure, convenient operation, low cost, etc.
Description
The utility model relates to a kind of air compressor gas source purification four-way valve.
In the existing air drying cleaning system between two exsiccators the checker of dry and regenerated way install the COMM communication that automatic control mechanism constitutes additional by four diaphragm valves and form.Though this COMM communication can realize the checker of working method between two exsiccators, it is big that this COMM communication needs four diaphragm valves to take up an area of, the cost height, and be used to adjust the control mechanism complexity of four diaphragm valves.
It is little that the purpose of this utility model provides a kind of volume, simple in structure, easy to use, and cheap Pneumatic four-way valve.
The purpose of this utility model is achieved in that it comprises valve body, and valve body is divided into front valve shell and rear valve body two-part; In the middle of the front valve shell silencing apparatus is housed, bilateral symmetry is equipped with simple and easy pneumatic stopping valve, and the suction port of pneumatic stopping valve is communicated with silencing apparatus; Shuttle valve is housed in the rear valve body.Use the time of the present utility model, the suction port of two simple and easy pneumatic stopping valves of front valve shell is inserted gas circuit respectively with after two air outlets of the shuttle valve of rear valve body are in parallel, respectively establish an exsiccator in the gas circuit of both sides, the control mouth of simple and easy pneumatic stopping valve links to each other with the control source of the gas respectively; When the control air pressure of a pneumatic stopping valve is reduced to a certain degree, pneumatic stopping valve opens jumping, and the gas of this side gas circuit is discharged emptying by silencing apparatus, makes the shuttle valve chamber in the rear valve body produce pressure reduction, shuttle valve makes the exsiccator that is communicated with this side be in reproduced state to this side closure; The gas that enters shuttle valve is discharged (pneumatic stopping valve of this side is in closed state under the effect of control air pressure) by another outlet of the shuttle valve on the four-way valve, and the exsiccator that is attached thereto is in dry working state; Vice versa.
The utility model has organically been installed two simple and easy pneumatic stopping valves on a valve body, a shuttle valve and a silencing apparatus are by realizing the control to whole gas circuit to the control of two simple and easy pneumatic stopping valves, so take up an area of few, simple in structure, easy to use, and cheap.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the attached view of Fig. 1.
Fig. 3 is the structural representation of valve body.
As shown in the figure, it comprises square valve body 1, and valve body 1 is divided into front valve shell 32 and rear valve body 18 two-part, and the middle part of front valve shell 32 is a silencing apparatus 17, and silencing apparatus 17 is made up of the stainless steel steel wire 14 that the side has aperture 16 rectangular enclosures 15 and interior dress; Link to each other with the rectangular enclosure 15 of silencing apparatus 17 and what be symmetrically distributed is two simple and easy pneumatic stopping valves 6, simple and easy pneumatic stopping valve 6 is made up of the spool 10 that cylindrical valve pocket 9 and end are embedded with sealing gasket 11, O-ring seals 13 is arranged in the groove of cylindrical valve pocket 9, have aperture 12 on the boss under the simple and easy pneumatic stopping valve 6 and communicate with suction port 8 on the flange plate 30 by intake duct, the top fixedly has the valve gap 4 that screw thread is controlled source of the gas mouth 3 by screw 2, between valve gap 4 and the valve body 1 seal ring 5 is arranged; The both sides of front valve shell 32 are fastened with flange plate 30 by screw 29, between flange plate 30 and the valve body 1 sealing gasket 31 are arranged; The stepped shaft circular shuttle valve chamber 22 of rear valve body 18 for having boss 33, link to each other by the suction port 20 on the fixing flange plate 21 of screw 19 on circular shuttle valve chamber 22 and the rear valve body 18, the circular shuttle valve core 24 that hollow has gas port 23 is snug fit in the stepped shaft cylinder shuttle valve chamber 22 that has boss 33, shuttle valve core 24 two ends are embedded with sealing gasket 25,22 two ends, circular shuttle valve chamber of rear valve body 18 are connected with locking bar 7 for fixedly had the flange plate of circular hole 26 by screw 27 between the screw.When using the utility model, earlier the suction port E of two simple and easy pneumatic stopping valves of front valve shell and F are inserted gas circuit respectively with after two air outlet C of the shuttle valve of rear valve body and D are in parallel, respectively establish an exsiccator in the gas circuit of both sides, the control mouth A of simple and easy pneumatic stopping valve links to each other with the control source of the gas respectively with B, make then gas as shown in Figure 2 direction enter the Pneumatic four-way valve, when the control air pressure of B mouth is reduced to a certain degree, the pneumatic stopping valve of the control that is subjected to opens jumping, F mouth on gas the past valve flange dish of this side gas circuit enters silencing apparatus and discharges emptying, produce pressure reduction in the shuttle valve chamber of rear valve body simultaneously, shuttle valve is to the D side closure, make the exsiccator that is communicated with this side be in reproduced state, the gas that enters shuttle valve is discharged (pneumatic stopping valve of this side is in closed state under the effect of control air pressure) by the C mouth, and the exsiccator that is attached thereto is in dry working state; Vice versa.
