Embodiment Construction

[0009] as attached figure 1 , 2 As shown, the output shaft of the air motor 10 is connected to the worm 4; the worm 4 meshes with the worm wheel 5; Turn on the air source to rotate the air motor 10, and the output shaft of the air motor 10 drives the worm 4 to reduce the speed ratio of the worm wheel 5, so that the screw 2 moves linearly downward along the axis of the internal thread in the worm wheel 5. This linear motion will force the spring seat 6 that is arranged on the lower end of the screw mandrel 2 to compress the small spring 7 and the large spring 8 for deformation and compression. When the deformed compression force of the small spring 7 and the large spring 8 are in balance with the set oil pressure in the pressure regulating valve, the boost adjustment in the pressure regulating valve is realized. Rotating the air motor 10 in the opposite direction then the screw mandrel 2 moves upwards, and the decompression adjustment in the pressure regulating valve is reali...

Abstract

The invention relates to a remote system for automatically controlling a pressure regulating valve, and belongs to the field of mechanical manufacturing. The remote system for automatically controlling the pressure regulating valve is used for remote control of the pressure regulating valve in an oil field drilling blowout prevention safety device. The remote system for automatically controlling the pressure regulating valve is composed of a handle, a screw rod, a locking handle, a worm wheel, a worm, a spring seat, a small spring, a large spring, an air motor, a valve body and the like. The remote system for automatically controlling the pressure regulating valve is characterized in that the air motor is arranged outside the valve body, and a worm wheel and worm device is arranged in thevalve body; an output shaft of the air motor is connected with the worm; and the worm wheel and the screw rod are connected with each other through an inner screw thread of the worm wheel and an outerscrew thread of the screw rod. The remote system for automatically controlling the pressure regulating valve has the advantages of convenient remote control, good pressure regulation stability, highdecompression speed, unchanged set value after gas cut-off and the like.

Description

technical field [0001] The invention relates to a remote system for fully automatic control of a pressure regulating valve, which is used for the automatic remote control of the pressure regulating valve in an oil field drilling blowout prevention safety device, and belongs to the field of mechanical manufacturing. Background technique [0002] At present, there are two driving control methods for the pressure regulating valve in the blowout prevention safety device of oilfield drilling: one is pure manual control, and this manual control method cannot realize remote control. The second is manual plus pneumatic control. Although the pneumatic control can realize remote control, since this kind of pneumatic control is to use the air pressure to fill the airbag in the pressure regulating valve to adjust the position control of the gate, so if you want to make the adjusted gate position Change just must keep the air pressure in the airbag to be constant all the time. Once the ...
