Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a pressure testing device for an angle valve. Background Technology

[0002] During operation, valves may leak hazardous media, causing safety accidents. Some valves may also rupture due to insufficient pressure, leading to further accidents. In pipeline systems requiring precise flow control, valves must have excellent throttling performance; otherwise, the overall system efficiency and product quality will be affected. Due to these safety hazards, valves must undergo rigorous pressure testing according to design specifications before leaving the factory. Pressure testing fixtures are indispensable in this process and must provide a good seal to ensure that all valve test parameters meet the specified pressure.

[0003] While ensuring safety during pressure testing, it is also necessary to ensure that the strength of the tooling meets the requirements. During valve pressure testing, pressure testing tooling must be used to seal the valve inlet and outlet to prevent leakage of the test medium. In addition to ensuring safety during the pressure testing process, the strength of the tooling must also meet the pressure testing requirements.

[0004] Because the back of the angle gate valve is cylindrical during pressure testing, the pressure testing fixture is not easy to stably seal the valve, which can easily lead to leakage and safety hazards. Therefore, it is necessary to design a special pressure testing fixture for small-diameter angle gate valves in order to ensure the health of the pressure testing personnel and to complete the pressure testing work efficiently.

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] like Figure 1-7As shown, an embodiment of the present invention provides a pressure testing device for an angle valve, comprising a vertical plate 100, a base plate 200, an upper blind post 300, a lower blind post 400, and a support block 500; there are two vertical plates 100; each vertical plate 100 has a circular hole 110; one side of the base plate 200 is operably associated with one vertical plate 100; the other side is operably associated with the other vertical plate 100; the upper blind post is inserted into the circular hole 110 of one vertical plate 100 and is operably associated with the vertical plate 100. The upper blind column is operably associated with the bottom plate 200; the head end 320 of the upper blind column contacts the inlet end of the valve body 900, and the tail end is connected to the test pressure bench; the lower blind column is operably associated with the bottom plate 200; the head end 430 of the lower blind column contacts the outlet end of the valve body 900, and the tail end is connected to the test pressure pump pipeline; the lower blind column is provided with a water inlet; the support block 500 is inserted into the round hole 110 of another vertical plate 100 and is operably associated with the vertical plate 100, and the support block 500 is used to support the valve body 900.

[0023] It should be noted that the head end of the lower blind column has an internal O-ring support, and the tail end is threaded to the test pump pipeline. Due to the unique structure of the angle gate valve, it faces many challenges during the pressure test. For example, when applying pressure, the valve is not easy to fix in the test fixture, and the bottom of the valve may warp. The design of the internal O-ring support can effectively seal the valve.

[0024] Due to the unique structure of the angle gate valve, the back of the valve is cylindrical. Using a traditional support block 500 results in too small a contact area with the valve, leading to insufficient support and potential leakage during pressure testing. To ensure effective pressure testing and a tight seal, the support block 500 is designed with the same cylindrical structure as the valve back.

[0025] The upper blind column has an O-ring at one end and a thread at the other end. The thread is connected to the pressure test bench. The O-ring end of the upper blind column fits into the valve body at 90° to ensure a tight seal.

[0026] In one embodiment, the base plate 200 is provided with a threaded through hole 210, and the outer surface of the lower blind post is provided with threads, and the threaded through hole of the base plate 200 is engaged with the threads of the lower blind post.

[0027] In one embodiment, the tail end 420 of the lower blind column is threaded and connected to the test pump pipeline.

[0028] In one embodiment, an internally supporting O-ring 600 is provided at the contact point between the head end 430 of the lower blind column and the outlet end of the valve body 900.

[0029] In one embodiment, the tail end 310 of the upper blind column is provided with threads and is threadedly connected to the test bench.

[0030] In one embodiment, an internally supporting O-ring 600 is provided at the head end 320 of the upper blind column and the inlet end of the valve body 900.

[0031] In one embodiment, the base plate 200 is connected to the two upright plates 100 by lower bolts 800.

[0032] In one embodiment, the upright plate 100 is provided with an upper threaded hole 120, which cooperates with the upper bolt 700.

[0033] Furthermore, the upper blind post and the upright plate 100 are fixed together by the upper bolts 700.

[0034] Furthermore, the end face of the support block 500 that contacts the valve body 900 is an arc-shaped structure 510, which fits the back of the valve body 900; the support block 500 and the upright plate 100 are fixed by upper bolts 700.

[0035] The specific implementation process of the above-mentioned angle valve pressure testing device is as follows: The pressure testing fixture consists of two vertical plates 100 on top and a base plate 200 below. The base plate 200 has a threaded hole for the lower blind column to enter the pressure testing fixture. The lower end of the vertical plate 100 is connected to the base plate 200 by a lower bolt 800. The middle part of the vertical plate 100 has a round hole 110 for the support block 500 and the upper blind column to enter the fixture. The upper end of the vertical plate 100 has a threaded hole that extends to the middle round hole 110. After the support block 500 and the upper blind column are installed, the upper bolt 700 is screwed in. The upper bolt 700 holds the support block 500 and the upper blind column in place to ensure that they do not wobble back and forth or left and right, thus providing a better fixing effect. Place the pressure testing fixture on the pressure testing bench, and put the valve into the fixture. The lower blind column has a threaded structure at the middle end that mates with the threaded structure of the fixture's base plate 200. The stop at the front end of the lower blind column is inserted into the valve's flow channel for positioning. The O-ring is designed with internal support to achieve a better sealing effect. The thread at the rear end of the lower blind column is connected to the pressure testing pump pipeline to facilitate pressure testing and leak reduction of the valve after sealing. The upper blind column is aligned with the valve inlet end through the round hole 110 in the middle of the fixture's vertical plate 100, and then through the upper blind column... The middle pin hole mates with the stud of the pressure testing fixture to provide positioning and clamping. The stud of the pressure testing platform ensures that the O-ring of the upper blind column fits tightly with the socket hole of the valve body 900, achieving a sealing effect. The front of the support block 500 is designed with the same arc shape as the back of the angle stop valve, and the rear end has the same structure as the upper blind column. It fits tightly with the back of the angle stop valve through the other end round hole 110. After the entire pressure testing fixture is fixed, the pressure medium is applied to the valve through the pressure testing pump, and the entire pressure testing platform is observed for any leakage.
