The implementation principle of the oil field pipeline oil pressure meter connecting valve with the pressure reducing and oil discharging function is as follows: when the device needs to be used, namely, the pressure gauge is replaced, firstly, a user needs to rotate the valve handle 201, the valve handle 201 drives the connected transmission shaft 2011 to start rotating, two worms 2012 are arranged on the surface of the transmission shaft 2011, at the moment, the two worms 2012 start rotating synchronously, the worm 2012 rotates to drive the worm wheel 2013 at the bottom to start rotating, and the central shaft of the worm wheel 2013 drives the screw rod shaft 202 to start rotating at the moment.

When the connection pipe 102 is sealed, a sealed oil chamber is formed inside the oil inlet chamber 1033, and a certain amount of hydraulic oil remains therein and has a certain pressure, so that the oil and pressure inside the oil inlet chamber 1033 need to be discharged.
The screw rod shaft 202 is continuously rotated to move, the guide wheel 2021 at the moment is driven to move along the vertical rolling groove 3012, the push plate 301 is not moved at the moment, namely, the choke assembly 300 at the moment is not at the working position, the screw rod sleeve 2024 is continuously moved, the pinch roller 2023 on the side wall of the screw rod sleeve 2024 is driven to start to move inwards, and finally the pinch roller 2023 is contacted with the inclined position on the surface of the groove 5031, so that the special-shaped block 503 provided with the groove 5031 on the pushing surface starts to move to two sides, and the unlocking position of the sealing door 500 is driven to be opened through the connecting bracket 502 and the inserted rod 501. In the movement of the plunger 501, the pressing spring 5041 of the surface is stretched, and the pressing spring 5041 facilitates the return operation at a later stage.
When the plunger 501 is separated from the sealing door 500, the sealing door 500 is not in a balanced state, and the pressure of the inner chamber of the oil inlet chamber 1033 is high, so that the lifting sealing door 500 starts to rotate around the rotation shaft 5001, and the inner torsion spring 5002 starts to rotate synchronously, thereby facilitating the later resetting.
When the sealing door 500 is opened, oil enters the oil discharge tank 401 from the oil inlet 4011, thereby discharging the oil in the oil pressure meter connecting valve shell 100, after the oil enters the oil discharge tank 401 from the oil inlet 4011 for a certain content, the floating ball 4022 is driven to move upwards through buoyancy, the piston 403 is lifted through the vertical rod 4021 to start moving, thereby the piston 403 is opened, the internal high-pressure gas passes through the pressure relief opening 4013, finally, the internal pressure is discharged, after the internal pressure is completely discharged, a user needs to rotate the oil outlet 4012 at the moment, the oil in the oil discharge tank 401 can be completely discharged through the oil outlet 4012, no crude oil remains in the whole oil pressure meter connecting valve, the later replacement of the pressure meter is safer, after the crude oil is completely discharged, the floating ball 4022 is driven to move downwards, the vertical rod 4021 is driven to move downwards synchronously, the piston 403 at the top is driven to move downwards, the sealing effect is further achieved, the sealing degree is improved through the top compression spring, and the limiting plate 4023 is arranged on the surface of the vertical rod 4021, and the limiting plate 4023 is in contact with the current position of the supporting plate 402, and limiting is carried out on the current position.
