[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Figure 1-Figure 3 The schematic diagram of the whole structure of a gas pipe network pressure regulating device of the utility model is shown in FIG. Figure 1-Figure 3 A gas pipe network pressure regulating device according to the present embodiment includes a gas pipeline 100, a pressure regulator 200 is arranged between the inlet and the outlet of the gas pipeline 100, a shell 300 for installing and protecting the pressure regulator 200 is arranged on the outer side of the pressure regulator 200, a pressure regulating main shaft 210 is provided on the upper part of the pressure regulator 200, a pressure regulating rod 400 which is perpendicular to the pressure regulating main shaft 210 is fixed on the top of the pressure regulating main shaft 210, crank rods 410 are vertically fixed at both ends of the top of the pressure regulating rod 400, an inner gear ring 420 which is coaxial with the pressure regulating main shaft 210 is fixed at the bottom of the pressure regulating rod 400, and a rotating drive component 500 which can drive the inner gear ring 420 to rotate radially back and forth is arranged on the upper part of the shell 300.

[0021] The rotation drive assembly 500 includes a power-assisting motor 510 fixedly mounted on the upper part of the outer shell 300, and a main gear 520 arranged at the output shaft end of the power-assisting motor 510 and meshing with the inner gear ring 420. When in use, the power-assisting motor 510 can drive the inner gear ring 420 to rotate through the main gear 520, thereby driving and assisting the pressure-adjusting rod 400 to rotate, making it easier and faster for the staff to turn the pressure-adjusting rod 400.

[0022] The crank rods 410 at both ends of the top of the pressure regulating rod 400 are respectively provided with a forward control button 430 and a reverse control button 440 which are connected to the signal of the power-assisting motor 510, and the forward control button 430 and the reverse control button 440 are located at the top of the crank rod 410. Here, by setting corresponding crank rods 410 at both ends of the pressure regulating rod 400, the worker can hold the two crank rods 410 with both hands respectively, which is more labor-saving than directly rotating the pressure regulating rod 400.

[0023] Specifically, in the present embodiment, when it is necessary to adjust the pressure of the voltage regulator 200, the staff can directly hold the crank rod 410 at both ends with both hands respectively, so that the rotation operation is easier. At the same time, the staff can use the thumb to press the forward control button 430 or the reverse control button 440 according to the needs of the pressure adjustment size and direction.

The avoidance hole makes it more convenient to turn the pressure regulating main shaft 210, and the design is simple and reasonable.

[0026] In summary, in a gas pipeline pressure regulating device of the present embodiment, when pressure regulation is required, the staff can directly hold the crank rod 410 at both ends with both hands respectively, so that the rotation operation is easier. At the same time, the staff can use the thumb to press the forward control button 430 or the reverse control button 440 according to the needs of the pressure regulation size and direction. At this time, the power-assisted motor 510 can drive the inner gear ring 420 and the pressure regulating rod 400 to perform power-assisted rotation through the main gear 520 after receiving the signal command. In this way, the twisting resistance caused by excessive pressure can be effectively reduced. At the same time, the staff can intuitively check the corresponding scale pointing of the pressure regulating pointer 610 and the pressure regulating dial 600, and check the pressure gauge reading at any time. In this way, the staff can quickly control the rotation stroke of the pressure regulating rod 400.
