Description

Technical Field

[0001] The utility model mainly relates to the technical field of valve detection equipment, in particular to a valve pressure side leakage device. Background Art

[0002] Valve pressure leakage test is an important means of inspecting valve quality and safety. For valves that have not undergone pressure leakage test, it is impossible to determine whether the sealing performance and pressure resistance of the valve meet the requirements during use. There may be a risk of leakage or failure under normal operating pressure. Valves that have not undergone pressure test may malfunction during use, causing media leakage and triggering safety accidents such as fire and explosion. Unqualified valves may affect the normal operation of the entire system, resulting in reduced system efficiency or even paralysis. Using valves that have not been pressure tested may cause frequent failures, increasing the cost of maintenance and replacement. Utility Model Content

[0012] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalent forms also fall within the scope defined in this application.

[0013] Example: Valve pressure side leakage device

[0014] like Figure 1 - As shown in 2, the valve pressure side leakage device, its specific structure includes:

[0015] A cylinder 1 with closed ends, a plurality of laterally arranged connecting pipes 2 are fixedly installed on the top of the cylinder 1, the connecting pipes 2 are communicated with the interior of the cylinder 1, and the upper ends of the connecting pipes 2 are fixedly installed with flanges 3, and the flanges 3 can be selected from different diameters. For the flanges 3, a pressure pipe 4 is fixedly installed on one side of the top surface of the cylinder 1, the pressure pipe 4 is communicated with the interior of the cylinder 1, and a pressure gauge 5 is fixedly installed on the upper end of the pressure pipe 4. An air intake pipe 6 is fixedly installed on one side of the cylinder 1.

[0016] A pipe joint 7 is fixedly mounted on the outer end of the air inlet pipe 6 .

[0017] The outside of the connecting pipe 2 is provided with a manual valve 8.

[0018] Working principle:

[0019] When the device is in use, the air inlet pipe 6 is connected to the high-pressure air pump through the pipe joint 7. When the valve is tested, the connecting flange of the valve is fixedly connected to the corresponding flange 3 by bolts. When the valve is installed, a sealing gasket is set on the top of the flange 3 to improve the sealing performance of the connection between the connecting flange of the valve and the flange 3. Flanges 3 of different diameters can be used to install valves of different types, thereby improving the detection of valves of different types by the device. The manual valve 8 can realize the on-off of the corresponding connecting pipe 2. When performing side leakage detection, the air inlet pipe 6 is used to connect the valve. Inject gas into the cylinder 1 and observe the pressure gauge 5. When the air pressure in the cylinder 1 reaches the set value, maintain the pressure. During the pressure maintenance period, the pressure change inside the cylinder 1 is judged by the pressure gauge 5. If the value of the pressure gauge 5 does not change during the pressure maintenance period, it means that the valve being tested meets the air tightness standard; if the value of the pressure gauge 5 decreases during the pressure maintenance period, it means that a valve is leaking. Close the manual valves 8 from left to right. When the value of the pressure gauge 5 no longer changes, it can be judged that the valve connected to the last manual valve 8 to be closed has a leakage problem, which is convenient for users.

[0020] In the interpretation of the present invention, it should be noted that the terms indicating orientation are only for the convenience of description and understanding, and are not the only limitation on the installation position of specific technical features, and do not exclude other possible installation methods.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
