[0015] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but the following embodiments are by no means any limitation to the present utility model.

[0016] See Figure 1 and Figure 2 The throttle manifold valve control device comprises an energy storage system A, a hydraulic oil charging system B and a hydraulic oil control system C arranged in a cabinet 19; wherein, the hydraulic oil tanks 18 of the energy storage system A and the hydraulic oil charging system B are arranged at the lower side of the cabinet 19, and other parts of the hydraulic oil charging system B and the hydraulic oil control system C are arranged at the upper side of the cabinet 19.

[0018] The hydraulic oil charging system B includes a hydraulic oil tank 18, an oil delivery main pipe, an electrically controlled oil delivery branch, and a manually controlled oil delivery branch; among them,

[0019] The oil delivery main pipe is composed of a two-piece internal thread ball valve 1, a globe valve, and a Y-type filter 2 connected in sequence through connecting pipes; the other end of the two-piece internal thread ball valve 1 is connected to the hydraulic oil tank 18 through a connecting pipe to form a connection, and the other end of the Y-type filter 2 is connected to a tee; among them, the two-piece internal thread ball valve 1 is used to control the oil intake of the hydraulic oil on the oil delivery main pipe, the globe valve is used to control the opening and closing of the oil delivery main pipe, and the Y-type filter 2 filters the hydraulic oil from the hydraulic oil tank 18 for the first time to initially filter out impurities in the hydraulic oil.

[0020] The electronically controlled oil delivery branch includes a horizontal piston pump 3, an explosion-proof three-phase asynchronous motor 4, an explosion-proof magnetic starter 5, an intelligent pressure switch 6, and a first check valve; the inlet end of the horizontal piston pump 3 is connected to the tee at the other end of the Y-type filter 2 through a connecting pipeline, its outlet end is connected to the inlet end of the first check valve through a connecting pipeline, and the outlet end of the first check valve is connected to the four-way connection at the accumulator connection end; the explosion-proof three-phase asynchronous motor 4 is electrically connected to the horizontal piston pump 3 to control the start and stop of the horizontal piston pump 3 through the explosion-proof three-phase asynchronous motor 4; the explosion-proof magnetic starter 5 is electrically connected to the explosion-proof three-phase asynchronous motor 4 and an external power supply respectively to control the start and stop of the explosion-proof three-phase asynchronous motor 4; the explosion-proof magnetic starter 5 is also electrically connected to the intelligent pressure switch 6, and at the same time the intelligent pressure switch 6 is connected to the connecting pipeline between the first check valve and the four-way through a connecting pipeline to send a low oil pressure signal to the explosion-proof magnetic starter 5 by monitoring the oil pressure in the connecting pipeline; among them, the explosion-proof magnetic starter 5 has two working modes; when the explosion-proof magnetic starter 5 is set to the automatic working mode, it automatically controls the start of the explosion-proof three-phase asynchronous motor 4 by receiving the low oil pressure signal, so as to store energy in the accumulator; when the explosion-proof magnetic starter 5 is set to the manual working mode, the on-site staff manually controls the explosion-proof magnetic starter 5 to start the explosion-proof three-phase asynchronous motor 4;

[0021] The manually controlled oil delivery branch consists of a manual pump 15 and a second check valve 14 connected in sequence through a connecting pipeline; the inlet end of the manual pump 15 is connected to the tee at the other end of the Y-type filter through a connecting pipeline, and the outlet end of the second check valve 14 is connected to the four-way connection at the accumulator connection end; the design of this manually controlled oil delivery branch is to meet the requirement that when there is no electricity, the on-site staff can pressurize the two bladder accumulators 9 by controlling the manual pump 15 to ensure that the equipment can maintain a continuous normal use state; the settings of the first check valve and the second check valve 14 are used to prevent the hydraulic oil from flowing back and causing damage to the horizontal piston pump 3 and the manual pump 15.

[0022] The hydraulic oil control system includes a main oil supply pipe, a first oil supply branch pipe, and a second oil supply branch pipe. Among them, the main oil supply pipe is composed of a Y-type filter 13, a relief valve 12, and a manual pressure reducing valve 11 connected in sequence through connecting pipes. The other end of the Y-type filter 13 is connected to a four-way connection at the accumulator connection end through a connecting pipe. The other end of the manual pressure reducing valve 11 is connected to one end of both the first oil supply branch pipe and the second oil supply branch pipe through a connecting pipe. The relief valve 12 on the main oil supply pipe is used to automatically overflow when the pipeline oil pressure is too high during the energy storage process. The manual pressure reducing valve 11 is used to ensure that the oil pressure transmission pressure in the pipeline is between 0 and 14 MPa through manual adjustment during the oil supply process, so as to ensure that each three-position four-way valve 17 can control the valves of the choke manifold at an appropriate pressure. The Y-type filter 13 is used to filter the hydraulic oil from the energy storage system A or the hydraulic oil charging system B for the second time to avoid damaging the valves of the choke manifold.

The outlet end of the two-piece internal thread ball valve 1 is connected to the return oil end of the hydraulic oil tank 18 through a connecting pipe. The outlet ends of the relief valve 12 and the manual pressure reducing valve 11 on the main oil supply pipe are respectively connected to the return oil end of the hydraulic oil tank 18 through connecting pipes. The oil outlet end of the precision needle valve 16 on the oil supply branch pipe and the oil drain ends of each three-position four-way rotary valve 17 are respectively connected to the return oil end of the hydraulic oil tank 18 through connecting pipes.

[0025] See Figure 2 , the specific working principle of the choke manifold valve control device is as follows:

[0026] When pressurizing the accumulator, the explosion-proof magnetic starter 5 in the manual working mode can manually control the start and stop of the flameproof three-phase asynchronous motor 4; when the flameproof three-phase asynchronous motor 4 starts, it drives the horizontal piston pump 3 to work through gears, so that the horizontal piston pump 3 pumps hydraulic oil into the two bladder accumulators 9 through movement. Since the energy storage main pipe of the bladder accumulator 9 is connected in parallel with the oil transmission main pipe provided with the overflow valve 12, once the conveying pressure of the hydraulic oil in the pipeline is higher than 21 MPa, it overflows through the overflow valve 12 to ensure that the pressure of the equipment will not be too high; when the explosion-proof magnetic starter 5 is in the automatic working mode, once it receives the low oil pressure signal sent by the intelligent pressure switch 6 due to detecting that the pressure in the oil transmission pipeline is lower than 18.9 MPa (that is, the pressure in the accumulator 9 is insufficient), the explosion-proof magnetic starter 5 drives the flameproof three-phase asynchronous motor 4 to start automatically, and when the explosion-proof magnetic starter 5 receives the high oil pressure signal sent by the intelligent pressure switch 6 due to detecting that the pressure in the oil transmission pipeline is higher than 21 MPa (that is, the pressure in the accumulator 9 is sufficient), the explosion-proof magnetic starter 5 drives the flameproof three-phase asynchronous motor 4 to stop automatically again, and so on; when there is no electricity at the operation site, the operator can also pressurize the bladder accumulator 9 by controlling the manual pump 15 to ensure that the equipment can always maintain a normal use state during the operation process.

[0027] When controlling the throttle manifold valve, the hydraulic oil of the bladder accumulator 9 is adjusted by the manual pressure regulating valve 11 to adjust the pressure in the manifold to 0 - 14 MPa, ensuring that each three-position four-way valve 17 can control the throttle manifold valve at an appropriate pressure; the two pressure gauges of the device respectively display the pressure of the accumulator and the pressure in the conveying pipeline.
