Description

Technical Field

[0001] This utility model pertains to auxiliary tooling for pressure regulators, and relates to structural and performance improvements of pressure regulating tooling for gas pressure regulators, particularly to a three-in-one special tool for regulating pressure in gas pressure regulators. Background Technology

[0002] Constructing a centralized natural gas supply network through gas pipelines improves the convenience and safety of people's lives and production. Gas pipeline systems utilize numerous pipes, valves, metering equipment, and control units. Among these, the gas pressure regulator, a part of the control unit, maintains stable outlet pressure through dynamic balancing during operation. Specifically, when the outlet pressure increases, the diaphragm is forced upwards, compressing the spring and closing the valve, reducing the gas flow; when the pressure decreases, the spring rebounds, opening the valve and increasing the gas supply to restore pressure.

[0003] The core functions of a gas pressure regulator include pressure stabilization and safety protection. Pressure stabilization is achieved by monitoring the outlet pressure in real time and automatically adjusting the flow rate to maintain the set pressure range. Safety protection involves a safety shut-off device that closes the valve to prevent overpressure when the pressure is abnormal. Structurally, a gas pressure regulator mainly consists of an inlet, valve, diaphragm, spring, regulating plate, and outlet. The diaphragm acts as a pressure sensing element, the spring provides the reaction force, and the valve controls the gas flow. To prevent accidental operation, the regulating plate is typically located inside a sleeve at the top of the gas pressure regulator, which also makes pressure regulation maintenance more difficult for operators, as common maintenance tools are not compatible.

[0004] Due to varying construction times of gas pipeline networks, the gas pressure regulators used in practice come in various specifications and with different pressure regulation methods, posing certain challenges to gas pipeline network maintenance. Common gas pressure regulators typically employ four types of regulating plate structures: internal hexagonal, external hexagonal, small T-type, and large T-type. Manual pressure regulation requires specific tools for each type, making them non-universal and exhibiting significant differences in specifications. Currently, there is a lack of tooling that can be used for pressure regulation on various types of gas pressure regulators. Utility Model Content

[0005] The purpose of this utility model is to provide a three-in-one special tool for regulating the pressure of a gas pressure regulator, which solves the problem that existing gas pressure regulator tools are not universally applicable.

[0006] To achieve the purpose of this utility model, the following technical solution is adopted: A three-in-one gas pressure regulator tool includes a cylindrical operating rod and an operating handle. The operating handle is mounted on the operating rod. One end of the operating rod is equipped with a first pressure regulating component and a second pressure regulating component. The first pressure regulating component is an external hexagonal pressure regulating head. The second pressure regulating component includes a connecting post and a limiting plate. The two ends of the connecting post are fixedly connected to the external hexagonal pressure regulating head and the operating rod, respectively. The limiting plate is symmetrically installed on both sides of the connecting post. The other end of the operating rod is open, and a third pressure regulating component, which is an internal hexagonal pressure regulating head, is provided on the inner wall of the open end.

[0007] To further achieve the objectives of this utility model, the following technical solutions may also be adopted: As described above, the gas pressure regulator three-in-one special tool has horizontal through holes on the upper and lower parts of the operating rod, and the operating handle is installed in the horizontal through hole on the upper or lower part of the operating rod.

[0008] As described above, the center distance between the horizontal through holes at the top and bottom of the operating rod in the three-in-one gas pressure regulator tool is 180-190mm.

[0009] The operating handle of the gas pressure regulator three-in-one special tool described above is cylindrical.

[0010] As described above, the gas pressure regulator three-in-one special tool has an internal hexagonal pressure regulating head with a side width of 32-33mm, an external hexagonal pressure regulating head with a side width of 20-21mm, and a distance of 55-56mm between the two sides of the limiting plate.

[0011] The advantages of this utility model are: This utility model is small in size, light in weight, and has a stable structure, making it easy to carry and use. One set of tools can be used to adjust the pressure of three types of gas pressure regulators, namely internal hexagon, external hexagon, and small T-type, which greatly improves the operational efficiency of gas pipeline pressure regulation and maintenance and reduces the time required for pressure regulation.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0016] In the description of the embodiments of this utility model, unless otherwise explicitly limited, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution. like Figures 1-3 The gas pressure regulator three-in-one special tool disclosed in this embodiment includes a cylindrical operating rod 1 and an operating handle 2, with the operating handle 2 mounted on the operating rod 1.

[0017] To accommodate the adjusting plate depth of gas pressure regulators and enable this special tool to be compatible with various sizes of regulators, transverse through holes 12 are provided at the upper and lower parts of the operating lever 1, allowing the operating handle 2 to be installed within these holes. This fully utilizes both ends of the operating lever 1 to install the first, second, and third pressure regulating components, respectively.

[0018] The first pressure regulating component can handle the pressure adjustment of the internal hexagonal adjustment plate, the second pressure regulating component can handle the pressure adjustment of the small T-shaped adjustment plate, and the third pressure regulating component can handle the pressure adjustment of the external hexagonal adjustment plate.

[0019] Therefore, when the first or third pressure regulating component is needed, the operating lever 1 is turned around, and then the operating handle 2 is installed with the transverse through hole 12 at different positions to perform the pressure regulating operation of the gas pressure regulator. The above structure ensures the depth to which the operating lever 1 extends into the gas pressure regulating sleeve and utilizes the lever principle to reduce the operator's workload. The operating handle 2 is cylindrical; to prevent slippage, anti-slip textures can be provided on the surface of the cylinder to improve friction.

[0020] In this embodiment, the center distance between the transverse through holes 12 at the top and bottom of the operating lever 1 is preferably set within the range of 180-190mm.

[0021] See also Figure 1 , Figure 2As shown, a first pressure regulating component is installed at the lower end of the operating lever 1. The first pressure regulating component includes an external hexagonal pressure regulating head 3, and the second pressure regulating component includes a connecting column 4 and a limiting plate 5. The two ends of the connecting column 4 are fixedly connected to the external hexagonal pressure regulating head 3 and the operating lever 1, respectively, and the limiting plate 5 is symmetrically installed on both sides of the connecting column 4.

[0022] The external hexagonal pressure adjusting head 3 is adapted to the internal hexagonal pressure adjusting plate, and the limiting plate 5 is adapted to the small T-shaped pressure adjusting plate. At the same time, the limiting plate 5 can increase the structural strength of the second pressure adjusting component and facilitate positioning.

[0023] See Figure 2 , Figure 3 As shown, the upper end of the operating lever 1 has an open structure, and a third pressure regulating component is provided on the inner wall of the open structure. The third pressure regulating component is an internal hexagonal pressure regulating head 6. The third pressure regulating component is adapted to the pressure regulating function of the external hexagonal adjusting pressure plate.

[0024] Based on the specifications of existing gas pressure regulators and the structural parameters of the adjusting plate, the width of the inner hexagonal pressure regulating head 6 across the sides in this embodiment is 32-33mm, the width of the outer hexagonal pressure regulating head 3 across the sides is 20-21mm, and the distance between the two sides of the limiting plate 5 is 55-56mm.
