Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure pressure relief valve equipment, in particular to a high-pressure electric control pressure relief valve equipment and its usage method. Background Art

[0002] Currently, manual pressure relief valves, pneumatic pressure relief valves, hydraulic control pressure relief valves, and electromagnetic pressure relief valves are used in high-pressure pressure relief valve equipment. However, such high-pressure pressure relief valve equipment has the following problems:

[0003] When the high-pressure pressure relief valve equipment is used in a hydraulic pump station equipment, it is affected by various factors:

[0004] Sometimes there is no external air source at the use site, and the pneumatic pressure relief valve cannot be used; sometimes the space at the use site is limited, and it is impossible to add an additional low-pressure hydraulic branch circuit for the hydraulic control pressure relief valve to use; sometimes full-automatic control of pressure boost and pressure relief is required during the use process, and the manual pressure relief valve cannot meet the use requirements; sometimes the equipment volume at the use site is limited, and the electromagnetic pressure relief valve is too large in volume and cannot be applied to the equipment. Summary of the Invention

[0005] To solve the above problems existing in the prior art, the present invention is to design a high-pressure electric control pressure relief valve equipment with a small volume, convenient and safe to use, and its usage method.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] A high-pressure electric control pressure relief valve equipment, comprising a valve body, an inner hexagon set screw, a steel ball, a ball support, a spring, a pressure rod, a coupling sleeve, a support sleeve, a motor, and an inner hexagon screw;

[0008] The valve body is fixedly connected with the support sleeve and the motor through a plurality of inner hexagon screws; there are three types of steel balls: steel ball B, steel ball C, and steel ball D; the output shaft of the motor is connected with the pressure rod through a coupling sleeve; the steel ball B is fixedly connected with the valve body through an inner hexagon set screw; the steel ball C is connected with the valve body through a ball support and a spring; the steel ball D is connected with the valve body through a pressure rod.

[0009] Further, the valve body is designed with corresponding high-pressure input interfaces, high-pressure output interfaces, and discharge outlets.

[0010] Further, the inner hexagon screw is an M4×80 screw.

[0011] Further, the inner hexagon set screw is an M8×8 screw.

[0012] Further, there are 4 inner hexagon screws.

[0013] Further, the steel ball B is a Φ5.5 steel ball.

[0014] Further, the steel ball C is a Φ3 steel ball.

[0015] Further, the steel ball D is a Φ2 steel ball.

[0016] Further, the spring is a Φ3.5×15 spring.

[0017] The present invention also claims the use method of the high-pressure electric control pressure relief valve device, including the following steps:

[0018] (1) Connect the high-pressure input interface and high-pressure output interface of the high-pressure electric control pressure relief valve to the high-pressure circuit of the hydraulic pump station equipment;

[0019] (2) Before the hydraulic pump station equipment connected to the high-pressure electric control pressure relief valve starts to boost pressure, rotate the motor of the high-pressure electric control pressure relief valve counterclockwise through the controller to reset and return to the origin. At this time, the high-pressure electric control pressure relief valve is in the locked state;

[0020] (3) After the hydraulic pump station equipment connected to the high-pressure electric control pressure relief valve finishes boosting pressure, rotate the motor of the high-pressure electric control pressure relief valve clockwise 2 turns through the controller. At this time, the high-pressure electric control pressure relief valve is in the pressure relief state, and the pressure in the high-pressure circuit of the hydraulic pump station equipment is discharged to the fuel tank of the hydraulic pump station equipment through the pressure relief outlet of the high-pressure electric control pressure relief valve;

[0021] (4) After the high-pressure electric control pressure relief valve completes the pressure relief work, if the hydraulic pump station equipment needs to boost pressure again, repeat steps 2 and 3.

[0022] Compared with the existing high-pressure pressure relief valve equipment, the present invention has the following beneficial effects:

[0023] 1. Since the present invention adopts an electric control drive method and abandons the structure that previously relied on hydraulic or pneumatic drive, the use of a gas source or low-pressure hydraulic source can be cancelled in the design of the entire pressure pumping station, and the overall structure of the equipment is simpler and the structural dimensions are more compact.

[0024] 2. Since the present invention adopts an electric control drive method, compared with pneumatic and hydraulic pressure relief valves, the high-pressure electric control pressure relief valve does not need to use a cylinder or hydraulic cylinder to drive the movement of the valve core, so its valve body size can be made smaller and the control is more stable.

[0025] 3. Since the present invention adopts an electric control drive method, compared with electromagnetic pressure relief valves, it is more compact in volume and safer to use.

[0026] 4. Since the present invention adopts an electric control drive method, it is also particularly suitable for fully automatic hydraulic pump station equipment. Description of the Drawings
