Description

Technical Field

[0001] This utility model relates to the field of mechanical maintenance tools, and in particular to a steam pressure reducing valve disassembly and assembly auxiliary tool. Background Technology

[0002] In the biopharmaceutical industry, steam pressure reducing valves are specialized valves primarily used to reduce high-pressure steam to the required low-pressure state. In steam systems, these valves stabilize system pressure, ensuring normal equipment operation. Furthermore, by precisely controlling steam pressure, they can optimize energy utilization and reduce operating costs. Existing steam pressure reducing valves are based on the pressure balance principle and mainly consist of an adjusting spring, a sensing diaphragm, a pilot valve, and a main valve. When the steam pressure is higher than the set value, the sensing diaphragm arches upward, causing the pilot valve to close and the main valve to open, allowing steam to flow through the main valve into the pressure relief pipeline, thereby reducing system pressure. When the steam pressure is lower than the set value, the sensing diaphragm sinks downward, causing the pilot valve to open and the main valve to close, thus cutting off the steam pressure relief path.

[0003] However, due to the characteristics of the medicine, the steam pressure reducing valve needs to be frequently disassembled and maintained during use. The steam pressure reducing valve has many heavy parts, and the current maintenance process involves lifting it up by hand to perform the maintenance operation, which is labor-intensive, inefficient, and poses a significant risk of personal injury or diaphragm damage in the event of an accident. Utility Model Content

[0004] The purpose of this utility model is to provide a separate assembly and disassembly tool for a steam pressure reducing valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steam pressure reducing valve disassembly and assembly tool includes a support plate, on which the pressure reducing valve to be disassembled and assembled is placed. A positioning post is provided on the upper surface of the support plate, and a mold assembly adapted to the valve port of the pressure reducing valve is sleeved on the positioning post. The mold assembly is used to insert into the valve port to stabilize the valve body of the pressure reducing valve. A clamping assembly for fixing the support plate is provided on the lower surface of the support plate.

[0007] As an alternative, the mold assembly includes several sleeves of progressively larger sizes. The outer wall of the sleeve of the previous size slides into the inner wall of the sleeve of the next size, and the inner wall of the sleeve of the smallest size slides into the outer wall of the positioning post. The number of sleeves is set according to the valve port size of the pressure reducing valve.

[0008] As an optional solution, the support plate, positioning post, and each sleeve are all made of nylon.

[0009] As an optional solution, the clamping assembly includes a C-shaped frame, the first side wall of the C-shaped frame abutting against the support plate and fixed with bolts, and an anti-slip block is provided on the first side wall of the C-shaped frame. A top pressure rod is provided on the second side wall of the C-shaped frame opposite to the first side wall. The first end of the top pressure rod is provided with a top pressure block opposite to the anti-slip block. The top pressure block and the anti-slip block cooperate to achieve the clamping function.

[0010] As an alternative, the top pressure rod is threadedly connected to the C-shaped frame, and the second end of the top pressure rod is equipped with a convenient rotating wheel.

[0011] As an alternative, the surfaces of the anti-slip block and the clamped part in contact with each other, as well as the surfaces of the top pressure block and the clamped part in contact with each other, are provided with protrusions to increase friction.

[0012] The beneficial effects of this utility model are as follows: This steam pressure reducing valve disassembly and assembly auxiliary tool provides mechanical support for pressure reducing valves of different specifications. After the pressure reducing valve to be disassembled and assembled is placed on the support plate, the valve port of the pressure reducing valve is then inserted through the appropriate mold assembly to ensure the stability of the pressure reducing valve's posture, so as to facilitate subsequent disassembly and assembly operations. This greatly reduces the difficulty of manual disassembly and assembly, improves work efficiency, and ensures the safety of the operation. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0018] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0021] Please see Figure 1 and Figure 2 As shown, this preferred embodiment provides a steam pressure reducing valve disassembly and assembly tool, including a support plate 1. The pressure reducing valve 11 to be disassembled and assembled is placed on the support plate 1. A positioning post 2 is provided on the upper surface of the support plate 1. A mold assembly adapted to the valve port of the pressure reducing valve 11 is sleeved on the positioning post 2. The mold assembly is used to insert into the valve port to stabilize the valve body of the pressure reducing valve 11. A clamping assembly for fixing the support plate 1 is provided on the lower surface of the support plate 1.

[0022] Thus, mechanical support is achieved for pressure reducing valves 11 of different specifications. After the pressure reducing valve 11 to be disassembled is placed on the support plate 1, the valve port of the pressure reducing valve 11 is then inserted through the matching mold assembly to ensure the stability of the pressure reducing valve 11, so as to facilitate subsequent disassembly and assembly operations. This greatly reduces the difficulty of manual disassembly and assembly, improves work efficiency, and ensures the safety of the operation.

[0023] Specifically, the mold assembly includes several sleeves 3 of progressively larger size. The outer wall of the sleeve 3 of the previous size slides with the inner wall of the sleeve 3 of the next size. The inner wall of the smallest sleeve 3 slides with the outer wall of the positioning post 2. The number of sleeves 3 is set according to the valve port size of the pressure reducing valve 11. Only the outermost sleeve 3 needs to be added or removed.

[0024] Optionally, the support plate 1, the positioning post 2, and each sleeve 3 are all made of nylon to reduce contact damage to the pressure reducing valve 11.

[0025] Specifically, the clamping assembly includes a C-shaped frame 4. The first sidewall of the C-shaped frame 4 is abutted against the support plate 1 and fixed by bolts 5. An anti-slip block 6 is provided on the first sidewall of the C-shaped frame 4. A top pressure rod 7 is provided on the second sidewall of the C-shaped frame 4 opposite to the first sidewall. A top pressure block 8 is provided at the first end of the top pressure rod 7, which is opposite to the anti-slip block 6. The top pressure block 8 and the anti-slip block 6 cooperate to achieve the clamping function. The clamping assembly can be clamped in any stable position on site to ensure the stable use of the entire steam pressure reducing valve disassembly and assembly tool.

[0026] Furthermore, the top pressure rod 7 is threadedly connected to the C-shaped frame 4, and the second end of the top pressure rod 7 is provided with a rotating wheel 9 for easy operation.

[0027] Furthermore, the anti-slip block 6 and the surface in contact with the clamped part, and the top pressure block 8 and the surface in contact with the clamped part are respectively provided with protrusions 10 to increase friction, so as to ensure that the clamping assembly and the clamped part are reliably fixed.

[0028] Usage process: 1) Select a stable clamping part, and rotate the top pressure rod 7 to make the top pressure block 8 cooperate with the anti-slip block 6 to clamp the clamping part, ensuring that the support plate 1 is stable and basically horizontal; 2) According to the valve port size of the pressure reducing valve 11, install an appropriate number of sleeves 3 on the positioning column 2 in sequence; 3) Place the valve body of the pressure reducing valve 11 on the support plate 1, and insert the sleeves 3 into the valve port to ensure the stability of the pressure reducing valve 11; 4) Perform the disassembly and assembly operation of the pressure reducing valve 11.
