Description

Technical Field

[0001] The utility model relates to the technical field of valve pressure testing, in particular to a high-pressure pressure testing tooling. Background Technique

[0002] Valve pressure testing is an important link to test the shell strength and sealing grade of valves, and it is also the main basis for detecting whether the valve performance meets the design requirements. According to the valve type, model specification, and pressure grade, a suitable test pump platform can be reasonably selected to achieve the pressure testing function. However, for some special valves, such as high-pressure and large-sized valves, these special valves cannot be directly installed on the test pump platform for testing during the test process, so it is necessary to configure a special test tooling to realize the pressure testing of the test valve.

[0003] At present, the Chinese patent with the publication number CN208140349U discloses a valve pressure testing platform, which includes a pressure testing platform body. A fixed seat is welded on the top of the pressure testing platform body. Two chutes are opened on the top of the pressure testing platform body, and the two chutes are respectively located on both sides of the fixed seat. A clamping plate is slidably installed in the chute, and the top of the clamping plate extends outside the chute. A valve connection block is fixedly installed on the side of the clamping plate close to the fixed seat. Two fixed blocks are welded on the top of the pressure testing platform body, and the two fixed blocks are respectively located on both sides of the two clamping plates. A connecting rod through hole is opened on the fixed block, and a connecting rod is slidably installed in the connecting rod through hole, and both ends of the connecting rod extend outside the connecting rod through hole. One end of the connecting rod close to the clamping plate is fixedly welded to the clamping plate, and a slide rod through hole is opened on the inner wall of the top side of the connecting rod through hole.

[0004] Although this kind of valve pressure testing platform is easy to operate and can quickly perform the work of pressure testing valves, however: this kind of pressure testing platform with this structure can only effectively test straight-through valves, but for some special high-pressure valves or large-sized valves, the above-mentioned pressure testing pump platform cannot achieve the test, so it is necessary to configure a corresponding pressure testing tooling to assist in realizing the pressure testing of the valves. Content of the Utility Model

[0005] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present utility model is to provide a high-pressure pressure testing tooling, which, as a connecting piece for assisting valve pressure testing, can perform pressure testing on some high-pressure and large-sized valves. The above technical purpose is achieved through the following technical solutions:

[0006] A high-pressure pressure test tooling, including a pump platform adapter. One side of the pump platform adapter is the liquid inlet end, and on the other end, there is a pressure digital display unit threadedly assembled with the pump platform adapter. The pressure digital display unit consists of a set of adapter blocks and a set of pressure gauges. The adapter block is a four-way structure. The pressure gauge is connected above the adapter block through a hose for detecting the medium pressure. One end of the adapter block is installed with the pump platform adapter, and the other end is installed with a connection unit for valve detection. The connection unit for valve detection includes a test valve inlet joint and a test valve outlet joint. A test valve is installed between the test valve inlet joint and the test valve outlet joint.

[0007] Further, there is a first needle valve between the adapter block and the pump platform connection block. One end of the first needle valve is threadedly assembled inside the pump platform adapter. There is a first transfer pipe between the first needle valve and the adapter block. The other end of the first needle valve is threadedly assembled inside the first transfer pipe. One end of the adapter block is threadedly assembled inside the first transfer pipe.

[0008] Further, one end of the adapter block is provided with a pressure relief unit. The pressure relief unit includes a second needle valve and a second transfer pipe. The end of the adapter block connected to the pressure relief unit is threadedly assembled inside the second transfer pipe. One end of the second needle valve is threadedly assembled inside the second transfer pipe.

[0009] Further, there is a union on one side of the test valve inlet joint. The test valve inlet joint is threadedly assembled inside the union. One end of the union is provided with an adapter. The end of the union connected to the adapter is threadedly assembled inside the adapter. The other end of the adapter is threadedly assembled outside the adapter block.

[0010] Further, one end of the test valve outlet joint is provided with a third needle valve. The third needle valve is threadedly assembled inside the test valve outlet joint.

[0013] As a connecting piece for assisting in installing special valves and pump platforms, the present utility model can be used for pressure test experiments of special valves. The overall versatility is relatively strong. The flexible installation method between the pump platform and the valve enables it to be installed on different pump platforms and valves. The unique pressure relief unit enables it to be used for dealing with high-pressure valves. Description of the Drawings

The pressure digital display unit consists of a set of adapter blocks 4 and a set of pressure gauges 7. The adapter block 4 is a four-way structure. The pressure gauge 7 is connected above the adapter block 4 through a hose for detecting the medium pressure. One end of the adapter block 4 is installed with the pump stand adapter 1, and the other end is installed with a connection unit for valve detection. The connection unit for valve detection includes a test valve inlet joint 10 and a test valve outlet joint 11. A test valve is installed between the test valve inlet joint 10 and the test valve outlet joint 11.

[0022] One end of the adapter block 4 is provided with a pressure relief unit. The pressure relief unit includes a second needle valve 12 and a second adapter pipe 13. One end of the adapter block 4 connected to the pressure relief unit is threadedly assembled inside the second adapter pipe 13, and one end of the second needle valve 12 is threadedly assembled inside the second adapter pipe 13.

[0023] One side of the test valve inlet joint 10 is provided with a union joint 9. The test valve inlet joint 10 is threadedly assembled inside the union joint 9. One end of the union joint 9 is provided with an adapter 8. The end of the union joint 9 connected to the adapter 8 is threadedly assembled inside the adapter 8. The other end of the adapter 8 is threadedly assembled outside the adapter block 4. The above structure forms an inlet device.

[0024] One end of the test valve outlet joint 11 is provided with a second needle valve 12. The second needle valve 12 is threadedly assembled inside the test valve outlet joint 11 to form an outlet device.
