When the through portion 1142 and the inner wall of the circular groove are threaded, the connecting member 4 is a screw. Of course, the number of the through portions 1142 and the circular grooves is not limited to two, and may be three, four or five as long as the number of the through portions 1142 and the circular grooves can be ensured to be consistent.

In an embodiment of the present invention, referring to fig. 1, when the cylinder 2 is installed in the valve body 1, the sealing disc 3 is embedded in the first limiting groove 2111. The height of sealed dish 3 equals with first spacing groove 2111's height, and the up end of sealed dish 3 supports the roof in first spacing groove 2111, and the lateral wall of sealed dish 3 supports the lateral wall in first spacing groove 2111, and the lower terminal surface of sealed dish 3 supports the diapire in holding tank 1141. So set up can make sealed dish 3 stably the inlay card in first spacing groove 2111, can not drop, and the gas tightness is good. In other embodiments, the sealing plate 3 can be mounted on the open end 114 of the valve body 1, and the same effects as those described above can be achieved, and the description thereof is omitted.

The piston 22 includes a piston body 221 and a push rod 222 connected to the piston body 221. The side wall of the piston body 221 is attached to the inner wall of the cylinder body 21. The push rod 222 is disposed in the axial direction of the piston body 221. When the piston 22 is mounted in the cylinder body 21, the push rod 222 extends in the direction of the valve body 1. The center of the sealing disc 3 is provided with a sliding chute 31 for the push rod 222 to slide. When the cylinder 2 is operated, the push rod 222 penetrates the slide groove 31 and extends to the inside of the discharge passage 11 of the valve body 1 through the opening end 114. The surface layer of the push rod 222 is tightly attached to the inner wall of the chute 31 without a gap. And the contact surface of the two is smooth, so that the push rod 222 can slide in the chute 31 very smoothly.

The free end of the push rod 222 extending into the discharge passage 11 is fixedly connected to the valve spool 12 installed in the discharge passage 11. A valve opening 113 is formed at the intersection of the inlet chamber 111, the outlet chamber 112 and the opening end 114. The valve body 12 is mounted above the valve port 113. When the cylinder 2 is activated, the piston 22 moves the valve core 12 to close or open the valve opening 113, thereby cutting off or opening the medium (discharged by the medium, such as gas, water, oil or other mixture) from the inlet chamber 111 to the outlet chamber 112 via the discharge passage 11.

The cylinder body 21 also includes a closed end 212 opposite the connecting end 211. In the cylinder body 21, the piston 22 and the closed end 212 form a first chamber 215, and the piston 22 and the seal disk 3 form a second chamber 216. When the piston 22 moves in the direction of the valve body 1, the space of the first chamber 215 becomes larger and the space of the second chamber 216 becomes smaller. When the piston 22 moves in the opposite direction to the valve body 1, the situation is reversed.

Referring to fig. 2, the outer wall of the cylinder body 21 is provided with a first passage opening 213 communicated with the first cavity 215, and the outer wall of the cylinder body 21 is further provided with a second passage opening 214 communicated with the second cavity 216.

In one embodiment of the present invention, the first passage opening 213 opens at the closed end 212. The first passage opening 213 is L-shaped, and one end thereof is opened on the sidewall of the cylinder body 21, and the other end thereof directly penetrates from the closed end 212 to the first cavity 215. Because the thickness of the closed end 212 is greater than the thickness of the side wall of the cylinder body 21, the first channel opening 213 is opened in the closed end 212, the space inside the closed end 212 can be effectively utilized, and the L-shaped structure is provided, so that the structure is more stable. The second opening 214 is opened on the side wall of the cylinder body 21 and close to the connecting end 211, so that the possibility that the side wall of the piston 22 blocks the second opening 214 in the sliding process of the piston 22 can be reduced. Further, referring to fig. 1, a stopper 32 is disposed on the upper end surface of the sealing disk 3, and the height of the stopper 32 is greater than the shortest distance from the second passage 214 to the upper end surface of the sealing disk 3. This arrangement is such that even if the piston 22 moves to a position close to the seal plate 3 and cannot continue to move, the side wall of the piston body 221 does not completely close the second passage opening 214.

A first solenoid valve (not shown) is installed inside the first passage port 213, and the first solenoid valve can close or open the first passage port 213. Meanwhile, a second solenoid valve (not shown) is installed inside the second passage port 214, and the second solenoid valve can close or open the second passage port 214.

The utility model provides a cylinder 2 also can replace by pneumatic cylinder or other drive mechanism to be not limited to this.

The utility model provides an integral type programme-controlled valve's theory of operation as follows:

the piston 22 is installed in the cylinder body 21, the sealing disc 3 is embedded in the first limit groove 2111 of the cylinder body 21 in a clamping manner, and then the connecting end 211 of the cylinder body 21 is opposite to and connected with the open end 114 of the valve body 1, so that the valve body 1 and the cylinder 2 form a whole.

When the exhaust passage 11 needs to be closed, the first solenoid valve is actuated to open the first passage port 213 to charge the first chamber 215. The piston 22 moves towards the valve body 1 to push the valve core 12 to close the valve opening 113.

When the vent passage 11 needs to be opened, the second solenoid valve is activated to open the second passage port 214 to charge the second chamber 216. The piston 22 moves away from the valve body 1 to move the valve core 12 away from the valve opening 113.
