Description

Technical Field

[0001] The utility model belongs to the technical field of steam pipe network blocking valve disassembly devices, and particularly relates to a special tool for quickly disassembling a steam pipe network water pressure test blocking valve. Background Art

[0002] Various steam pipes, boilers and other equipment operating in industrial production are equipped with special water pressure test valve plugging devices. According to the production process requirements, after the construction of the boiler is completed or the overhaul is completed, the valve plugging device needs to be disassembled and a special plugging plate needs to be installed to perform a water pressure test. After the test is completed, the plugging plate is removed to restore normal circulation function.

[0003] The existing disassembly method uses many tools and instruments, and the valve is usually located at the highest point of the boiler. The operation process is dangerous, there is a risk of tool collapse, and the dedicated graphite sealing ring is easily damaged. The spare parts are expensive and the sealing effect is affected.

[0004] The order of disassembling and inspecting the valve is: after loosening the upper nut, remove the two external workpieces first. However, the lower pressure plate is difficult to remove due to the extrusion and tightening force of the external workpiece and the influence of thermal expansion and contraction. The process does not allow the use of heating the outer ring method, and this method is not effective. If the method is incorrect, the force during the disassembly process is uneven, which can easily cause damage to the external workpiece and even damage to the pressure plate and valve body, burying major safety hazards for the safe operation of subsequent equipment such as boilers or steam pipelines, and even forcing them to be replaced as a whole, resulting in increased maintenance costs and disruption of the process flow.

[0005] Therefore, it is urgent to design a more reasonable and safe disassembly tool for such situations to solve such problems, which does not increase the labor intensity of workers and can achieve equipment disassembly safely, conveniently and quickly. Utility Model Content

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figure 1As shown, a special tool for quickly disassembling a plugging valve for a water pressure test in a steam pipeline network includes a vertical plate 1. The vertical plate 1 is the main structural support part of the entire tool, carrying and fixing various components to ensure the stability of the tool and the transmission of force during the disassembly process. By rationally designing the shape of the vertical plate 1, the tool has strong stability and reliability and can work effectively.

[0022] Jacks 4 are installed on both sides of the bottom of the vertical plate 1 to provide the tensile force required for disassembly. The bottom of the jacks 4 press against the outer wall of the valve, and through the application of force, the pressure plate can be removed from the valve. A connecting plate 5 is installed at the center of the bottom of the vertical plate 1. The connecting plate 5 connects to the pressure plate to facilitate force transmission. The edge of the connecting plate 5 is provided with a nut 6 for connecting the pressure plate and the connecting plate 5. The top of the pressure plate is provided with a corresponding threaded hole.

[0023] The following is a detailed description of the design of the above key components:

[0024] A handle 2 is provided on the top of the vertical plate 1. The handle 2 is welded to the top of the vertical plate 1 and has good strength and wear resistance. A pull ring 3 is provided in the center of the handle 2. The vertical plate 1 can be easily pulled up through the handle 2, and the pull ring 3 is convenient for connecting external equipment.

[0025] The vertical plate 1 is T-shaped, with jacks 4 located at the bottom of the horizontal arms on either side of the plate. The vertical portion of the T-shaped structure supports pressure, while the horizontal arms secure the jacks 4. The vertical plate 1 is constructed from high-strength alloy steel, offering excellent tensile and compressive strengths and high-temperature resistance. The surface is polished or spray-coated for rust resistance, ensuring corrosion resistance and extending service life.

[0026] The connecting plate 5 is a circular plate, the structure of which corresponds to the shape of the pressure plate and conforms to the optimal force distribution. It is also made of high-strength alloy steel, which has excellent strength and rigidity. It is welded to the bottom of the vertical plate 1. A number of nuts 6 are distributed in a circle around the center of the connecting plate 5, and the number is determined according to actual needs.

[0027] The nut 6 is a long threaded push rod, which is used to rotate the connecting pressure plate downward. A gasket 7 is provided on the nut 6 to protect the connecting plate 5 and prevent wear.

[0028] A round rod passes through the center of the pull ring 3, and the diameter of the round rod matches the diameter of the pull ring 3. Passing the round rod through the pull ring 3 allows the lever principle to increase the force arm to rotate the pressure plate out, while also making it easier to apply force to pull the pressure plate out. It is important to note that when using the round rod, the jack 4 must be removed during rotation.

[0029] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
