Detailed description of the invention
In order to be better understood from technique scheme, below in conjunction with Figure of description and specific embodiment, technique scheme is described in detail.
As shown in Figure 1, a kind of differential reversing assembly of gas control described in the present embodiment, including valve body 1, A2, B6 two commutation room it is sequentially provided with in valve body 1, air chamber A3, B4, C7, D8, exhaust chamber 5, and the most through, above-mentioned commutation room and air chamber are correspondingly provided with air inlet 22, gas outlet 62, valve port A31, valve port B41, valve port C71, valve port D81, air vent and acoustic filter 51 respectively；Being provided with reversing slide valve A21 in commutation room A2, this reversing slide valve A21 and air chamber A3, air chamber B4 are corresponding；Being respectively equipped with inflation guiding valve 53 in air chamber A3 and air chamber B4, this inflation guiding valve 53 is connected with the reversing cylinder 52 on valve body 1 respectively；Being provided with reversing slide valve B61 in commutation room B6, this reversing slide valve B61 and air chamber C7, air chamber D8 are corresponding；The regeneration gas adjustable valve 9 connected by trachea it is provided with between air chamber C7, air chamber D8.
Wherein, in the present embodiment, described valve body 1 is made up of with lower valve body 1 upper valve body 1, is connected by screw is fixing between upper valve body 1 with lower valve body 1.
Operation principle: by the timing break-make between pneumatic control air chamber, form different gas circuits and produce draught head, makes reversing slide valve A21 and reversing slide valve B61 move left and right, thus opens or closes corresponding valve, reaches the purpose automatically switched.
As shown in Figure 2, in reversal valve pressurising works, gas enters in commutation room A2 from air inlet 22, and now, reversing slide valve A21 is positioned at air chamber B4 side, and air chamber B4 is closed, reversing slide valve B61 is positioned at air chamber D8 side, and is closed by air chamber D8, and gas is through the connected entrance of commutation room A2 and air chamber A3, enter air chamber A3, and enter air chamber C7 to drying tower A, again drying tower A top output by valve port C71 from valve port A31 output.Now, most gas is through the connected entrance of air chamber C7 with commutation room B6, enter commutation room B6, and discharge from gas outlet 62, and the gas of little part is through regeneration gas adjustable valve 9, enter air chamber D8, and export bottom valve port D81 output to drying tower B, again drying tower B by valve port B41 entrance air chamber B4, until the pressure balance between air chamber A3 and air chamber B4, air chamber C7 and air chamber D8, drying tower A and drying tower B.
During commutation, when the inflation guiding valve 53 in air chamber B4 is under the promotion of reversing cylinder 52, opening the passage of air chamber B4 and exhaust chamber 5, the gas in drying tower B is back in air chamber B4 from valve port B41, and is discharged to air by the air vent on exhaust chamber 5 and acoustic filter 51.Now, owing to air chamber B4, air chamber D8 are in the low-pressure state of aerofluxus, air chamber A3, the intracavity air pressure of air chamber B7 are respectively higher than the intracavity air pressure of air chamber B4, air chamber D8, so reversing slide valve A21, reversing slide valve B61 slide into air chamber B4, air chamber D8 one end from air chamber A3, air chamber C7 one end under the active force of draught head respectively, now, drying tower A work；When the inflation guiding valve 53 in air chamber A3 is under the promotion of reversing cylinder 52, opening the passage of air chamber A3 and exhaust chamber 5, the gas in drying tower A is back in air chamber A3 from valve port A31, and is discharged to air by the air vent on exhaust chamber 5 and acoustic filter 51.Now, owing to air chamber A3, air chamber C7 are in the low-pressure state of aerofluxus, air chamber B4, the intracavity air pressure of air chamber D8 are respectively higher than the intracavity air pressure of air chamber A3, air chamber C7, so reversing slide valve A21, reversing slide valve B61 slide into air chamber A3, air chamber C7 one end from air chamber B4, air chamber D8 one end under the active force of draught head respectively, now, drying tower B works, and switch operation completes.
The above, it it is only presently preferred embodiments of the present invention, not the present invention is made any pro forma restriction, although the present invention is disclosed above with preferred embodiment, but it is not limited to the present invention, any those skilled in the art, in the range of without departing from technical solution of the present invention, when the technology contents of available the disclosure above makes a little change or is modified to the Equivalent embodiments of equivalent variations, in every case it is the content without departing from technical solution of the present invention, any simple modification above example made according to the technical spirit of the present invention, equivalent variations and modification, all still fall within the range of technical solution of the present invention.
