The automatic centering hydraulic sealing device is mainly characterized in that: the combined action of the fixed sliding plate and the inner spherical sliding plate is utilized to realize the omnibearing automatic centering and eccentric adjustment of the sealer. Utilize hand pump hydraulic system to compress tightly well head seal packing, the main seal is sealed for conventional work, and vice sealed for not stopping the well change main seal's is sealed, and the position of the switching-over valve rod in the main and vice sealed through manual adjustment phase sealing member and the emergence effect. The hydraulic oil lubricates the seals at the same time. The lower end of the sealer is provided with a well sealing mechanism, so that automatic well closing caused by accidental falling of the polish rod is realized.
The automatic centering hydraulic sealing device implements omnibearing automatic centering and deviation adjustment of a sealer. When the horsehead, the polished rod and the well head are not aligned and are not on a straight line or the natural positions of the sucker rod and the packing are not on the same vertical line, the eccentricity exists. The inner spherical sliding plate can move on the plane of the fixed sliding plate, the sealer is in contact with the spherical surface of the inner spherical sliding plate to perform spherical surface sliding, and the eccentricity is adjusted under the combined action of the spherical surface sliding and the plane sliding. When the oil well normally works, the main seal is in a working state, the auxiliary seal is in a deblocking state, and only when the main seal fails, manual operation is performed to enable the auxiliary seal to work, and the main seal is decompressed and replaced. The function of the sealer is realized as follows: manually shaking the hand pump plunger, sucking hydraulic oil in a loop into a pump cavity of the hand pump through an oil inlet valve, pumping the hydraulic oil into a main oil way by the plunger through an oil outlet valve simultaneously, enabling a reversing valve rod of a main seal to be in a state that the main oil way is communicated with the main seal, enabling the hydraulic oil to enter a main seal hydraulic cylinder, pushing a main seal piston to extrude seal packing, and enabling the main seal to work; meanwhile, the auxiliary sealing reversing valve is in a loop communication state, and the auxiliary sealing does not work. When the main seal fails and needs to be replaced, the positions of the two reversing valves are manually switched, so that the auxiliary seal works, and the main seal can be replaced without stopping the well. When the polish rod of the oil well is accidentally broken and falls off, the well sealing sliding plug and the balance ejector rod of the well sealer stretch out under the action of the compression spring force, and the ejector rod is embedded into the sliding plug to realize well mouth sealing. When a wellhead is installed, the main sealing reversing valve rod is located at a position communicated with a main oil path of the blowout preventer, the hand-operated pump is used for pressurizing, the sliding plug hydraulic cylinder and the ejector rod hydraulic cylinder act simultaneously, the sliding plug and the ejector rod are in a recovery state, and smooth passing of a polish rod is ensured.

The pressure gauge anti-theft device is characterized in that: the pressure difference between two sections of the sliding piston is used for pushing the opening and closing of the steel ball and the valve seat, and the opening and closing function is realized when the meter is changed. The manual opening of the cone valve is arranged to play a dual-switching role. The replacement of the pressure gauge is unlocked by authorization. The manometer is protected by protective sheath and toughened glass, avoids artificial destruction. The oil duct is arranged in a curve mode, and even if a pressure gauge is not installed, external force cannot push the steel balls open, so that crude oil flows out.
During the operating condition, the sliding piston is under the effect of the pressure difference of both ends face, and the spring that the compressed promotes the steel ball, leaves the disk seat, and the oil circuit intercommunication transmits pressure, and the manometer shows well head pressure. When the pressure gauge is replaced, the pressure difference between two end faces of the sliding piston changes along with the unloading of the pressure gauge, the well head pressure pushes the sliding piston and compresses the spring to enable the steel balls to be seated back to the valve seat, and the oil way is closed. The cone valve is opened manually and is in a normally open state.
