DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the drawings.

[0025] Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Secondly, the present utility model will be described in detail in conjunction with the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of explanation, the sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0027] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0028] The present utility model provides a pressure test device applicable to multi-specification valves. By setting a valve pressure test assembly and a pressure test adaptation assembly, it can be adapted to pressure test valves of different specifications during use, and during the pressure test of a batch of valves, another batch of valves can be pre-assembled and installed. The assembled pressure test installation structure greatly reduces the valve installation time and improves the valve pressure test efficiency.

[0029] Figures 1 - 3 Shown is the overall structural schematic diagram of an embodiment of a pressure test device applicable to multi-specification valves of the present utility model. Please refer to Figures 1 - 3 , the main structures of this embodiment include: a valve pressure test assembly and a pressure test adaptation assembly.

[0030] The valve pressure test assembly is used for valve pressure testing. The valve pressure test assembly includes a set pressure test tank body 11, a support plate 12 fixed to the bottom surface of the pressure test tank body 11, an air inlet pipe 13 communicated with the pressure test tank body 11, a pressure gauge 14 communicated with the top surface of the pressure test tank body 11, and a connecting pipe 15 communicated with the pressure test tank body 11;

[0031] During specific use, the connecting pipe 15 is connected to the valve body 24. At this time, gas is injected through the air inlet pipe 13, and the pressure change is observed through the pressure gauge 14 to judge the pressure test effect of the valve.

[0032] The pressure test adaptation assembly is used to improve the adaptability of valve pressure testing and improve the pressure test efficiency. Specifically, the pressure test adaptation assembly includes an internal thread 27 opened inside the connecting pipe 15, a threaded pipe 21 connected to the internal thread 27, a first valve plate 22 connected to the threaded pipe 21, a first hole position 23 opened on the surface of the first valve plate 22, a valve body 24 arranged above the first valve plate 22, a second valve plate 25 connected to the valve body 24, and a second hole position 26 opened on the surface of the second valve plate 25;

[0033] During specific use, the user fits the first valve plate 22 with the second valve plate 25, and uses a long threaded rod to pass through the first hole 23 and the second hole 26, and locks it with a nut, so that the valve body 24 can be connected to the threaded pipe 21. When pressure testing is required, the user connects the threaded pipe 21 to the connecting pipe 15 through the internal thread 27. In the process of using such a structural design, when pressure testing valve bodies 24 of different specifications, only the first valve plate 22 that meets the specifications needs to be replaced. And during the process of pressure testing a batch of valve bodies 24, the user can connect another batch of valve bodies 24 with the corresponding first valve plates 22 for assembly. When the pressure-tested valve body 24 is removed, it can be directly connected through the corresponding threaded pipe 21 of the assembled valve to be pressure-tested. This greatly shortens the pressure testing and installation time of the valve, without the need to twist a large number of bolts to install the same valve, improving the pressure testing efficiency.

[0034] Furthermore, through the provided locking assembly, the installed valve body 24 can be locked twice to prevent connection loosening and affecting the pressure testing effect of the valve.

[0035] Specifically, it further includes a locking assembly. The locking assembly includes an annular plate 31 fixed on the outer side wall of the connecting pipe 15, a notch groove 32 opened on the surface of the annular plate 31, and a long shaft 33 arranged in the notch groove 32. The locking assembly further includes a cylinder 34 sleeved on the long shaft 33, an L-shaped hook 35 connected to the cylinder 34, and a strong magnet 36 arranged at the front end of the L-shaped hook 35.

[0036] During specific use, the user pushes the L-shaped hook 35 upward. The L-shaped hook 35 drives the cylinder 34 to rotate on the surface of the long shaft 33 until the L-shaped hook 35 covers the top surface of the second valve plate 25, and the strong magnet 36 adsorbs to the second valve plate 25, so as to lock the connection of the valve plate twice and prevent disconnection from affecting the pressure testing effect.

[0037] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The exhaustive description of these combinations is omitted in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
