Description

Technical Field

[0001] This utility model relates to the technical field of pressurizing pressure limiting valve bodies, and specifically to a pressure limiting valve body pressurizing tool. Background Technology

[0002] A pressure relief valve is a critical safety device installed on a pressure vessel or pressure pipeline system. Its core functions are pressure relief protection, media discharge, pressure stabilization, and prevention of explosions or equipment damage.

[0003] Before leaving the factory, pressure relief valve bodies need to undergo airtightness testing. This requires sealing all oil ports on the valve body, then pressurizing the valve body with air, and finally using soapy water to check for leaks in the air passages and threaded connections. However, there is currently a lack of dedicated tooling for airtightness testing of pressure relief valve bodies. As a result, existing airtightness testing methods require a significant amount of time to seal each oil port individually and then pressurize the valve body with air hoses. This process is time-consuming and inefficient. Utility Model Content

[0004] To address the aforementioned problem of high testing efficiency due to significant time wasted during the testing process, this invention proposes a pressure-pressurizing fixture for a pressure-limiting valve body. The fixture includes a base plate with two upright plates on it. An inflation plate is positioned between the two upright plates, and a valve body is connected to the inflation plate. An inflation port is located on the side of the inflation plate facing away from the valve body, and this port communicates with the valve body for pressurizing it. A diamond-shaped gasket is also positioned between the inflation plate and the valve body.

[0005] A further feature of this invention is that a support column is threadedly connected to the base plate, the support column is arranged perpendicular to the base plate, and the top end of the support column abuts against the valve body to support the valve body.

[0006] A further feature of this invention is that the inflation plate is connected to the valve body via double-ended bolts.

[0007] A further feature of this invention is that a flange is provided along the edge of the side surface of the diamond-shaped gasket near the valve body to enhance the sealing performance, and an annular flange is also provided on the diamond-shaped gasket corresponding to each oil hole on the valve body to block each oil hole.

[0008] The beneficial effects of this utility model are as follows:

[0009] The air inflator plate enables the valve body to be installed quickly, while the air inlet allows high-pressure air to be injected into the valve body, thus achieving rapid installation and pressurization of the valve body to improve testing efficiency. Furthermore, the diamond-shaped gasket improves the sealing between the oil hole of the valve body and the air inflator plate, and achieves a rapid sealing effect on the oil hole, ensuring the accuracy of airtightness testing.

[0016] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] refer to Figure 1 This utility model proposes a pressure relief valve body pressurization tool, including a base plate 1, on which two upright plates 2 are connected by bolts. The two upright plates 2 are arranged parallel to each other, and an inflation plate 3 is arranged between the two upright plates 2. The two sides of the inflation plate 3 are connected to the upright plates 2 by bolts so that the inflation plate 3 can be fixedly connected to the two upright plates 2.

[0018] The valve body 4 is connected to the inflatable plate 3 by a double-ended bolt. That is, two threaded holes are opened on the inflatable plate 3 corresponding to the two connecting holes on the valve body 4. One end of the double-ended bolt is threadedly connected to the threaded hole, and the other end of the double-ended bolt passes through the mounting hole of the valve body 4 and is threadedly connected to a nut, thereby realizing the purpose of installing the valve body 4 onto the inflatable plate 3.

[0019] An air inlet is provided on the air inlet plate 3 corresponding to an oil hole on the valve body 4. The end of the air inlet facing away from the valve body 4 is connected to an air inlet 31. The air inlet 31 is used to connect to a pressure device, so that the pressure device can inject high-pressure air into the valve body 4 through the air inlet 31, so that the air pressure inside the valve body is maintained at 600Kp.

[0020] refer to Figure 3 , 4 Furthermore, a diamond-shaped gasket 6 is installed between the inflation plate 3 and the valve body 4. The diamond-shaped gasket 6 has the same surface shape as the valve body 4 on the side closest to the inflation plate 3, and a flange 61 is provided along its edge to further achieve a sealing effect on the valve body 4. An annular flange 61 is also provided inside the diamond-shaped gasket 6 corresponding to each oil hole on the valve body 4, so that each oil hole is individually isolated, preventing the oil holes from affecting each other's sealing performance.

[0021] refer to Figure 2 The base plate 1 is also threaded with a support column 5. The support column 5 is set perpendicular to the base plate 1. The top of the support column 5 is set against the valve body 4 to support the valve body 4. It should be noted that since the support column 5 is threaded to the base plate 1, rotating the support column 5 can adjust the height of the support column 5, thereby adjusting the support force of the support column 5.

[0022] Testing process: First, install the valve body 4 onto the inflation plate 3 and adjust the height of the support column 5.

[0023] Next, use a pressure testing device to fill the valve body 4 with 600Kp of air and maintain the pressure for 30 seconds. Then, apply soapy water to the two vent holes on the top of the valve body 4 and observe whether bubbles are generated. If no bubbles are generated in either vent hole, it means that the air passages and the pressure sleeve inside the valve body 4 are not connected and there is no leakage. If bubbles are generated in one vent hole, it means that the piston sleeve is leaking and the valve port sleeve is leaking.

[0024] Finally, the tested valve body is disassembled and replaced with the other valve body 4 to be tested.

[0025] In summary, the air inflator 3 enables the valve body 4 to be installed quickly, while the air inlet 31 allows high-pressure air to be injected into the valve body 4, thereby achieving the purpose of quick installation and pressurization of the valve body 4, which improves the testing efficiency. Furthermore, the diamond-shaped gasket 6 can improve the sealing between the oil hole of the valve body 4 and the air inflator 3, and achieve the effect of quickly blocking and sealing the oil hole, ensuring the accuracy of the airtightness test.
