Description
Technical field
The utility model belongs to well mouth of oil well back pressure controller, especially can prevent a kind of wellhead back pressure controller of well liquid height temperature flash distillation.
Background technology
At present, what each elephant of China adopted the phenomenon of heavy oil wells high temperature flash distillation is gate control, and this gate can't reach the effect of control high temperature flash distillation, and management difficulty is big.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of wellhead back pressure controller, this wellhead back pressure controller, sealing clamp is arranged on base, interior stage clip and outer stage clip are arranged on the sealing clamp, there is regulator board the upper end of interior stage clip and outer stage clip, and regulator board is installed in the lower end of central axis, is moved up and down by central axis rotation drive regulator board and adjusts oil well and go out hydraulic coupling.
The technical scheme in the invention for solving the technical problem is: a kind of wellhead back pressure controller is by shell, loam cake, gland, limit base, handwheel, the handwheel screw, central axis, the gland screw, seal, regulator board, the loam cake screw, ring gasket, outer stage clip, interior stage clip, gland, sealing clamp, O-ring seal, base is formed, its special character is: sealing clamp is arranged on the base, interior stage clip and outer stage clip are arranged on the sealing clamp, there is regulator board the upper end of interior stage clip and outer stage clip, regulator board is installed in the lower end of central axis, drives regulator board by central axis rotation and moves up and down and adjust oil well and go out hydraulic coupling.
The beneficial effects of the utility model are: novel structure, and easy to operate, can reach the effect that prevents the high temperature flash distillation, safe and reliable.
