Description

Technical Field

[0001] This utility model relates to the field of valve testing technology, and in particular to an integrated valve pressure testing machine. Background Technology

[0002] A valve pressure testing machine is a specialized device for testing the strength and sealing performance of valves, widely used in valve manufacturing, petrochemical, power, and water supply industries. It simulates the pressure environment of valves under actual operating conditions to perform pressure tests and leak detection, ensuring their safety and reliability. It is an important tool for guaranteeing valve quality. In operation, valve pressure testing machines typically clamp the valve between upper and lower pressure plates for testing. However, different valve specifications require different sized testing machines, especially considering the need for pressure plate replacement. Existing testing machines are limited in their usage, only capable of testing one type of valve, and the pressure plates cannot be disassembled and replaced, resulting in low flexibility and restricted application. Therefore, a solution has been proposed in this technology.

[0003] For example, Chinese Patent Publication No. CN207763751U discloses a valve pressure testing machine, comprising a bracket, an upper top plate, a lower bottom plate, a telescopic device, an upper pressure plate, and a lower pressure plate. The upper top plate is mounted on the upper end of the bracket; the upper pressure plate has an externally threaded post in the middle of its upper end; the lower end of the telescopic shaft has an internally threaded hole; and the externally threaded post is threaded into the internally threaded hole. The upper pressure plate and telescopic shaft of this invention are detachable, allowing for the replacement of upper pressure plates of different sizes to accommodate valves of different dimensions.

[0004] The above application still has shortcomings. When the upper pressure plate needs to be replaced, the lower pressure plate needs to be repeatedly rotated and removed, and the new lower pressure plate needs to be rotated and fixed. The operation is cumbersome and laborious, and the installation and removal operation is inconvenient. At the same time, multiple different upper pressure plates need to be stored separately. When replacing the upper pressure plate, it is necessary to find the upper pressure plate, which is inconvenient and affects the replacement efficiency.

[0005] Therefore, it is necessary to provide an integrated valve pressure testing machine to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide an integrated valve testing machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: an integrated valve pressure testing machine, comprising a lower base plate, two symmetrically distributed supports fixed on the top surface of the lower base plate, an upper top plate fixed to the top of the two supports, a hydraulic cylinder fixed to the top of the upper top plate, the output end of the hydraulic cylinder facing downwards and a mounting plate fixed to the output end of the hydraulic cylinder, multiple annularly distributed insert rods detachably connected to the column side of the mounting plate, upper pressure plates fixed to the ends of the multiple insert rods, and the multiple upper pressure plates being of different sizes, an assembly / disassembly assembly for assembling and disassembling the upper pressure plates provided on the mounting plate, a lower pressure plate fixed to the top surface of the lower base plate, and multiple annularly distributed insertion holes a opened on the column side of the mounting plate, the insert rods being inserted into the insertion holes a.

[0008] As a further embodiment of this utility model, the side of the mounting plate is provided with a socket b corresponding to and communicating with the socket a, the mounting and disassembly assembly includes a post inserted into the socket b, and the side of the rod is provided with a locking hole that matches the post.

[0009] As a further embodiment of this utility model, each end of the plurality of inserts is fixed with a connecting rod, and a circular plate is provided on one side of the mounting plate, with the ends of the plurality of connecting rods away from the inserts fixed to the circular plate.

[0010] As a further embodiment of this utility model, a support plate is fixed on the side of the mounting plate, and a nut sleeve is fixed at the end of the support plate. A threaded rod is internally threaded into the nut sleeve, and one end of the threaded rod is rotatably connected to the circular plate.

[0011] As a further embodiment of this utility model, a rubber pad is attached and fixed to the end of the insertion rod away from the upper pressure plate.

[0012] As a further embodiment of this utility model, an end plate is fixed on the end of the threaded rod away from the circular plate, and a plurality of ribs arranged in a ring are provided on the side of the end plate.

[0013] As a further embodiment of this utility model, a limiting plate for limiting the movement of the connecting rod is fixed on the side of the mounting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the mounting and disassembly assembly can simultaneously lock multiple insert rods inserted into multiple sockets a, thereby fixing multiple upper pressure plates of different sizes on the mounting plate. This allows the mounting plate to always carry multiple upper pressure plates of different sizes, thus avoiding the loss of upper pressure plates and eliminating the need to search for upper pressure plates when replacing them. This effectively improves the convenience and efficiency of upper pressure plate replacement. When it is necessary to replace the upper pressure plate, the mounting and disassembly assembly can simultaneously unlock multiple insert rods on the mounting plate, allowing different upper pressure plates to be installed at the bottom of the mounting plate for use. This allows for the replacement of upper pressure plates of different sizes according to different valve sizes. Attached Figure Description

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figure 1-7 This utility model provides an integrated valve pressure testing machine, including a lower base plate 5. Two symmetrically distributed supports 4 are fixed on the top surface of the lower base plate 5. An upper top plate 14 is fixed to the top of the two supports 4. A hydraulic cylinder 6 is fixed to the top of the upper top plate 14. The output end of the hydraulic cylinder 6 is facing downwards, and a mounting plate 3 is fixed to the output end of the hydraulic cylinder 6. Multiple annularly distributed insert rods 9 are detachably connected to the column side of the mounting plate 3. The ends of the multiple insert rods 9 are all fixed to upper pressure plates 8, and the multiple upper pressure plates 8 are of different sizes. The mounting plate 3 is provided with a disassembly and assembly assembly 1 for disassembling the upper pressure plates 8. A lower pressure plate 7 is fixed on the top surface of the lower base plate 5. Multiple annularly distributed insertion holes a10 are opened on the column side of the mounting plate 3, and the insert rods 9 are inserted into the insertion holes a10. Within 10; during use, the mounting and disassembly assembly 1 can simultaneously lock multiple insert rods 9 inserted into multiple sockets a10, thereby fixing multiple upper pressure plates 8 of different sizes on the mounting plate 3. This allows the mounting plate 3 to always carry multiple upper pressure plates 8 of different sizes, thus avoiding the loss of upper pressure plates 8 and eliminating the need to search for upper pressure plates 8 when replacing them. This effectively improves the convenience and efficiency of upper pressure plate 8 replacement. When it is necessary to replace the upper pressure plate 8, the mounting and disassembly assembly 1 can simultaneously unlock the multiple insert rods 9 on the mounting plate 3, allowing different upper pressure plates 8 to be installed at the bottom of the mounting plate 3 for use. This allows for the replacement of upper pressure plates of different sizes according to different valve sizes.

[0027] Further as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the side of the mounting plate 3 has a socket b12 that corresponds to and communicates with the socket a10. The mounting and disassembly assembly 1 includes a post 106 inserted into the socket b12, and the side of the rod 9 has a locking hole 107 that matches the post 106. In actual operation, the post 106 is inserted into the socket b12 and the locking hole 107 to lock the rod 9 inserted into the socket a10, thereby fixing the upper pressure plate 8 to the mounting plate 3. This allows the mounting plate 3 to always carry multiple upper pressure plates 8 of different sizes, thus avoiding the loss of the upper pressure plate 8 and eliminating the need to search for the upper pressure plate 8 when replacing it.

[0028] Further as Figure 3 , Figure 4 and Figure 5As shown, it is worth noting that each end of the multiple insertion posts 106 is fixed with a connecting rod 105. A circular plate 104 is provided on one side of the mounting plate 3. The ends of the multiple connecting rods 105 away from the insertion posts 106 are fixed to the circular plate 104. A support plate 108 is fixed on the side of the mounting plate 3. A nut sleeve 109 is fixed to the end of the support plate 108. A threaded rod 101 is internally threaded into the nut sleeve 109. One end of the threaded rod 101 is rotatably connected to the circular plate 104. Different upper pressure plates 8 can be installed. When the threaded rod 101 is rotated, the threaded rod 101 drives the circular plate 104 and multiple connecting rods 105 to move synchronously, thereby driving multiple insert pins 106 to move out of multiple locking holes 107, unlocking multiple upper pressure plates 8. Different upper pressure plates 8 can be removed and replaced and installed at the bottom of the mounting plate 3. Then, the threaded rod 101 is rotated in the opposite direction, so that multiple insert pins 106 are inserted into multiple locking holes 107 synchronously, and the upper pressure plates 8 are relocked, realizing the replacement of the upper pressure plates 8.

[0029] Further as Figure 3 As shown, it is worth noting that a rubber pad 13 is attached and fixed to the end of the insertion rod 9 away from the upper pressure plate 8; during actual operation, the rubber pad 13 is used to prevent the end of the insertion rod 9 from wearing in the insertion hole a10.

[0030] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that an end plate 102 is fixed on the end of the threaded rod 101 away from the circular plate 104, and multiple ribs 103 arranged in a ring are provided on the side of the end plate 102. In actual operation, the threaded rod 101 can be easily rotated and adjusted by the end plate 102 and the ribs 103, which facilitates operation.

[0031] This solution has the following working process: The insert post 106 is inserted into the insertion hole b12 and locking hole 107, thereby locking the insert rod 9 inserted in the insertion hole a10, thus fixing the upper pressure plate 8 to the mounting plate 3. This allows the mounting plate 3 to always carry multiple upper pressure plates 8 of different sizes, preventing the loss of the upper pressure plate 8 and eliminating the need to locate the upper pressure plate 8 when replacing it. When replacing different upper pressure plates 8, the threaded rod 101 is rotated... The threaded rod 101 drives the circular plate 104 and multiple connecting rods 105 to move synchronously, thereby moving multiple insert pins 106 out of multiple locking holes 107, unlocking multiple upper pressure plates 8. Different upper pressure plates 8 can be removed and the insert pins 9 on the upper pressure plate 8 can be inserted into the insertion hole a10 at the bottom of the mounting plate 3. Then, the threaded rod 101 is rotated in the opposite direction so that multiple insert pins 106 are simultaneously inserted into multiple locking holes 107, relocking the upper pressure plate 8 and realizing the replacement of the upper pressure plate 8.

[0032] Further as Figure 2 and Figure 6 As shown, it is worth noting that a limiting plate 11 is fixed on the side of the mounting plate 3 to limit the movement of the connecting rod 105. In actual operation, when the threaded rod 101 drives the insertion post 106 to move out of the locking hole 107, the limiting plate 11 stops the connecting rod 105 to prevent the insertion post 106 from completely coming out of the insertion hole b12, thus preventing excessive movement and adjustment of the insertion post 106 and facilitating the next reverse movement and adjustment of the insertion post 106.

[0033] In summary: The mounting and disassembly assembly 1 can simultaneously lock multiple insert rods 9 inserted into multiple sockets a10, thereby fixing multiple upper pressure plates 8 of different sizes onto the mounting plate 3. This allows the mounting plate 3 to always carry multiple upper pressure plates 8 of different sizes, thus preventing the loss of upper pressure plates 8 and eliminating the need to search for upper pressure plates 8 when replacing them. This effectively improves the convenience and efficiency of upper pressure plate 8 replacement. When it is necessary to replace the upper pressure plate 8, the mounting and disassembly assembly 1 can simultaneously unlock the multiple insert rods 9 on the mounting plate 3, allowing different upper pressure plates 8 to be installed at the bottom of the mounting plate 3 for use. This allows for the replacement of upper pressure plates of different sizes according to different valve sizes.

[0034] The hydraulic cylinder 6 can be purchased from the market. The hydraulic cylinder 6 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
