[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1:

[0030] Refer to Figure 1 and Figure 2 which shows a structural example of the pressure distribution device given in this example.

[0031] As can be seen from the figure, this pressure distribution device specifically includes an electric control valve assembly 1. The output end of the electric control valve assembly 1 is fixedly connected with a connecting pipe 2. A jacking pipe 3 is arranged at the upper end of the connecting pipe 2. The upper end of the jacking pipe 3 is fixedly connected with a pressure relief valve assembly 4. The front end of the connecting pipe 2 is fixedly connected with a control assembly 5.

[0032] Further refer to Figure 3 and Figure 4, the pressure relief valve assembly 4 in this embodiment specifically includes a valve pipe 401, a pressure relief pipe 402, a square pipe 403, and a motor 404. Among them, a pressure relief pipe 402 is arranged on the right side of the valve pipe 401, the upper end of the valve pipe 401 is fixedly connected to the square pipe 403, a moving plate 407 is arranged inside the square pipe 403, a pressure sensor 408 is fixedly connected to the lower end of the moving plate 407, a motor 404 is fixedly connected to the upper end of the square pipe 403, a screw rod 405 is fixedly connected to the output end of the motor 404, a spring 410 is sleeved outside the screw rod 405, and a valve block 411 is fixedly connected to the lower end of the spring 410.

[0033] As a further explanation, the pressure relief valve assembly 4 in this embodiment further includes a sliding rod 406 and a pressing plate 409. The sliding rod 406 is fixedly connected to the top end inside the square pipe 403, and the pressing plate 409 is fixedly connected to the lower end of the pressure sensor 408. The pressure relief valve assembly 4 arranged in this way cooperates with the electric control valve assembly 1 to form a pressure distribution device. The electric control valve assembly 1 adjusts the fluid pressure distributed from the main pipeline to the branch pipeline. When the pipeline pressure is too high, the pressure is relieved through the pressure relief valve assembly 4, thereby ensuring the safety of the pipeline.

[0034] As a further explanation, in this pressure relief valve assembly 4, the square pipe 403 is adapted to the moving plate 407. The moving plate 407 is slidably connected to the sliding rod 406 and is threadedly connected to the screw rod 405. Here, by arranging the square pipe 403 and the moving plate 407, starting the motor 404 drives the screw rod 405 to rotate. The rotation of the screw rod 405 drives the threadedly connected moving plate 407 to move up or down along the sliding rod 406, thereby adjusting the stroke of the spring 410, and thus adjusting the pressure of the spring 410 to set the safety pressure of the pressure relief valve assembly 4.

[0035] As a further explanation, in this pressure relief valve assembly 4, the upper and lower ends of the spring 410 are respectively fixedly connected to the pressing plate 409 and the valve block 411. The upper part of the outside of the screw rod 405 is provided with threads, and the lower part of the outside is a smooth cylinder. The valve block 411 is slidably connected to the screw rod 405. Arranged in this way, through the arranged valve block 411, when the pressure inside the connecting pipe 2 is too high, the valve block 411 is pushed upward to move along the screw rod 405, and the spring 410 is compressed until the pressure relief pipe 402 is connected to the valve pipe 401, and the high-pressure fluid sprays out from the pressure relief pipe 402 to release the pressure and maintain the safety of the pipeline. The pressure sensor 408 is arranged between the moving plate 407 and the pressing plate 409, and senses the pressure in contact with the spring 410 in real time and transmits the value to the control board 503.

[0036] Embodiment Two:

[0037] On the basis of the solution of Embodiment One, this embodiment further gives an optimized solution.

[0038] In this embodiment, the specific composition solution of the control component 5 in this pressure distribution device is given.

[0039] Refer to 1 and Figure 5 In this embodiment, the control component 5 specifically includes a housing 501, a storage battery 502, a warning light 504, a control panel 505 and a speaker 506. The storage battery 502 and a control board 503 are arranged inside the housing 501. The warning light 504 is fixedly connected to the upper end of the housing 501, and the control panel 505 and the speaker 506 are arranged at the front end of the housing 501. The control component 5 with such a structure can effectively manage and control the pressure distribution device.

[0040] As a further illustration, the housing 501 here is fixedly connected to the electric control valve assembly 1 and the connecting pipe 2 through a connecting rod. The input end of the electric control valve assembly 1 is fixedly connected to the output end of the connecting pipe 2 and an external pipeline. In such a structure, the electric control valve assembly 1 is adjusted through the control panel 505, and the opening degree of the electric control valve assembly 1 is adjusted, thereby adjusting the fluid pressure.

[0041] As a further illustration, the control board 503 here is electrically connected to the electric control valve assembly 1, the motor 404, the pressure sensor 408, the storage battery 502, the warning light 504, the control panel 505 and the speaker 506. Thus, through the control board 503, a preset safety pressure value is set. When the value of the pressure sensor 408 exceeds the preset safety pressure value, the flashing warning light 504 is started and the speaker 506 is started to generate an audible and visual alarm to remind the staff. The storage battery 502 is provided to supply emergency power for the control component 5.

[0042] The specific composition of the control board 503 here is not limited and can be determined according to actual needs. For example, it can be implemented by adopting an existing stable and reliable control board solution. Its composition and operation process are well-known technologies to those skilled in the art and will not be elaborated here. As an example, the control board here mainly includes a panel, a main control board and a drive board. The respective functions, compositions and connections of the panel, the main control board and the drive board cooperate to achieve the preset safety pressure value. When the value of the pressure sensor 408 exceeds the preset safety pressure value, the flashing warning light 504 is started and the speaker 506 is started to generate an audible and visual alarm. This is a well-known technology to those skilled in the art and will not be elaborated here.

[0043] For the pressure distribution device solution given in this embodiment, the following specifically describes its reference process.

[0044] Combined with Figures 1 to 5As shown, when the present pressure distribution device is in use, a preset safety pressure value is set through the control panel 505. The electric control valve assembly 1 is adjusted through the control panel 505 to adjust the opening degree of the electric control valve assembly 1, thereby adjusting the fluid pressure. The motor 404 is started to drive the screw 405 to rotate. The rotation of the screw 405 drives the threaded moving plate 407 to move up or down along the slide rod 406, thereby adjusting the stroke of the spring 410, and thus adjusting the pressure of the spring 410. The safety pressure of the pressure relief valve assembly 4 is set. The pressure sensor 408 is arranged between the moving plate 407 and the pressing plate 409, and senses the pressure in contact with the spring 410 in real time and transmits the value to the control board 503. When the pressure inside the connecting pipe 2 is too high, the valve block 411 is pushed upward and moves along the screw 405, and the spring 410 is compressed until the pressure relief pipe 402 is connected to the valve pipe 401, and the high-pressure fluid sprays out from the pressure relief pipe 402 to release the pressure and maintain the safety of the pipeline. When the value of the pressure sensor 408 exceeds the preset safety pressure value, the flashing warning light 504 is started and the speaker 506 is started to generate an audible and visual alarm to remind the staff.

[0045] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
