A fountain tree 54 is mounted on a pipe head with an adapter for the head of the tubing, a cuff of the secondary seal of the suspension of the tubing, valves, plugs, an instrument flange for temperature control and a needle gauge for monitoring pressure in the well 1.

The tubing string 13 is mounted in the production string 11 to form an annular space 55 that is sealed with a check valve or ball safety valve.

To call the flow of formation fluid into the layout of the underground production equipment, the tubing string 13 includes at least one production packer 56 and a circulation valve 57 mounted above it, configured to pass geophysical instruments through it, and also to allow annular communication space 55 of the well with the internal cavity of the column 13 tubing in the open state and ensuring the tightness of the annular space 55 in the closed state yanii.

In the initial position, the through holes 21 of the sleeve 20 are blocked by the throttle valve 22, the control valve is closed.

To open the control valve using the main hydraulic drive mechanism 34, a working fluid is supplied under pressure to the piston chamber 38, which moves the piston 37. The piston 37 moves together with the shank 29 of the rod 28, on which it is rigidly fixed. The rod 28, moving, drives the throttle valve 22 of the cellular locking unit 17, opening the control valve and adjusting the flow rate of the transported medium. Through an open valve, gas or gas condensate enters the outlet pipe 19 and then into the gas manifold. During the movement of the rod 28, the working element of the mechanism 36 of the return movement of the rod accumulates kinetic energy, which is converted into potential energy.

To close the control valve, the flow of working fluid into the sub-piston chamber 38 of the main hydraulic drive mechanism 34 is stopped, the overpressure in the sub-piston chamber 38 is removed and the piston 37 is returned to its original position with the help of the working member of the rod return mechanism 36 due to the accumulated kinetic energy converted into potential when opening the control valve.

This engagement facilitates the transmission of torque without restricting the longitudinal movement of the rotary motion transducer 41 with respect to rotary support block 40. Due to the spiral resting on the wall of the glass 42 in the figured cover 39 of the housing 33 of the combined drive The rotary motion transducer 41 rotates along the axis of the rod 28, abutting against the thrust bearing 48, it moves the rod 28 and the throttle valve 22, opening the through holes 21 of the sleeve 20. During the movement of the rod 28, the working element of the rod return mechanism 36 accumulates kinetic energy that is transformed into potential.

The valve closes by rotating the slewing-rotary unit 40 in the opposite direction and the resulting reverse bias of the rotary motion transducer 41, which provides the possibility of a reverse movement of the rod 28, and the latter is carried out by the mechanism 36 of the reverse movement of the rod by unloading its working body due to the accumulated kinetic energy at opening the control valve.

The implementation of the throttle valve 22 in the form of a hollow cylinder with an inner annular protrusion 23, having supporting ends 24, almost equidistant from the outer ends 25 of the throttle valve 22, which is rigidly detachably connected to the stem 28 using the nut 30 and bushings 31 with end collars, makes it possible to in case of wear, turn the throttle valve 180 ° and thereby extend the life of the throttle valve 22, since the outer ends 25 of the throttle valve of the cellular locking assembly 17 are identical to the mating seal the saddle made in the sleeve 20.
