The adjusting screw 16 drives the pressure relief port 19 and the adjusting plate 17 to slide in the valve body 9, thereby adjusting the pressure of the adjusting plate 17 on the spring 15, so that the spring 15 pushes the switch plate 14 to press on the valve plate 13 to block the pressure relief port 19, and the switch plate 14 is pushed open under a certain pressure to exhaust and release pressure; the adjusting screw 16 is rotatably mounted on the valve plate 13 through a bearing, and the switch plate 14 is slidably mounted on the outer side of the adjusting screw 16 through a sliding hole; the surface of the valve plate 13 is provided with a pressure relief port 19, and the surface of the switch plate 14 is provided with a sealing plate, and the sealing plate The positions of the plate and the pressure relief port 19 correspond to each other, which is convenient for blocking and pressure relief; a connecting hole 18 is provided at one end of the adjusting plate 17 and the valve body 9, which is convenient for rapid pressure relief when the pressure is too high; a recovery hole 8 is provided on the inner side of the connecting shell 4, and the inner side of the connecting shell 4 is connected with the inner side of the connecting seat 2 through the recovery hole 8, which is convenient for oil and gas to be recovered during use; a rotor 5 is rotatably installed on the inner side of the connecting seat 2, and an eccentric vane 6 is fixedly installed on the outer side of the rotor 5. When looking up, the motor 1 drives the rotor 5 and the eccentric vane 6 to rotate to extract and recover the oil and gas.

[0023] From the above description, it can be seen that the utility model has the following beneficial effects: when in use, through the transmission and self-locking effect of the transmission worm wheel 10 and the transmission worm 11, the transmission worm 11 is driven to rotate by the rotating head 12 and the adjusting screw 16 is driven to rotate and adjusted, thereby ensuring the stability of the position of the adjusting plate 17, thereby avoiding the phenomenon of pressure control changes after long-term use.

[0024] Example 2: Please refer to Figures 1 to 4 As shown, on the basis of embodiment 1, the utility model provides a technical solution: a sealing ring 7 is provided at the connection between the pump casing 3 and the connecting casing 4, a spring piece 20 is provided inside the sealing ring 7, and the cross-sectional shape of the spring piece 20 is set to be U-shaped. The connecting casing 4 is installed on the pump casing 3 for fixed use, and the sealing ring 7 is pushed to be tightly attached to the connection between the pump casing 3 and the connecting casing 4 by the elastic force of the spring piece 20.

The rotating head 12 is rotated by a tool, and the rotating head 12 drives the transmission worm 11 to rotate. The transmission worm 11 drives the transmission worm wheel 10 and the adjusting screw 16 to rotate. The adjusting screw 16 drives the pressure relief port 19 and the adjusting plate 17 to slide in the valve body 9, thereby adjusting the pressure of the adjusting plate 17 pressed on the spring 15, so that the spring 15 can push the switch plate 14 to press on the valve plate 13 to block the pressure relief port 19, and push the switch plate 14 open under a certain pressure to exhaust and relieve pressure. After adjustment, the self-locking effect of the transmission worm wheel 10 and the transmission worm 11 can reduce the pressure of the adjusting screw 16 rotating again after adjustment, thereby affecting the pressure of the adjusting plate 17 pressed on the spring 15, and the pressure of the pressure relief can be guaranteed after long-term use.
