Description

Technical Field

[0001] The utility model relates to the technical field of safety valves, in particular to a universal adapter for safety valve testing. Background Technique

[0002] The safety valve test is an important process to ensure the normal operation of safety valves in pressure vessels, pipelines and other equipment. The main function of the safety valve is to automatically open when the pressure in the equipment exceeds the predetermined limit value to release the excess pressure, thereby preventing the equipment from exploding or other dangerous situations.

[0003] Due to the different pore diameters of the flange mounting holes of the safety valve, different pore diameter flanges need to be configured for assembly and docking with the flange of the safety valve during each experiment of the safety valve. This is rather cumbersome during operation, and a large amount of time will be consumed in replacing different flanges during the test. Content of the Utility Model

[0004] The purpose of the utility model is to provide a universal adapter for safety valve testing to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A universal adapter for safety valve testing includes

[0007] Flange 1, on one end of which Flange 2 is movably installed, and a number of standard flange holes are regularly arranged on Flange 1;

[0008] A connecting pipe is arranged between Flange 1 and Flange 2, and a fixing mechanism is arranged between the connecting pipe and Flange 1.

[0009] Preferably, both ends of the connecting pipe are respectively provided with a threaded head and a threaded groove. The connecting pipe is threadedly connected to Flange 1 through the threaded head, and the connecting pipe is threadedly connected to Flange 2 through the threaded groove;

[0010] Preferably, the fixing mechanism includes a movable sleeve. The movable sleeve is movably installed outside the connecting pipe. Bolt holes are provided at the four corners of the movable sleeve and Flange 1, and the bolt holes between the movable sleeve and Flange 1 are fixedly connected by bolts;

[0011] Preferably, a sealing ring is movably arranged outside the connecting pipe near the threaded head;

[0012] Preferably, the diameter of Flange 1 is larger than the diameter of the movable sleeve;

[0013] Preferably, the diameter of the movable sleeve is larger than the diameter of the sealing ring.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] This universal joint plate for safety valve testing does not require a large number of different flanges for matching during experiments. Only by adjusting the direction of the safety valve mounting holes on the standard flange holes can the assembly and debugging efficiency of the safety valve be effectively improved during the assembly and debugging test process.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1-4 shown, a technical solution provided by the present invention:

[0023] A universal joint disc for safety valve testing, comprising a first flange 1. At one end of the first flange 1, a second flange 2 is movably installed. A number of standard flange holes 3 are regularly arranged on the first flange 1. A connecting pipe 4 is arranged between the first flange 1 and the second flange 2. A fixing mechanism is arranged between the connecting pipe 4 and the first flange 1. Threaded heads 5 and threaded grooves 6 are respectively arranged at both ends of the connecting pipe 4. The connecting pipe 4 is threadedly connected to the first flange 1 through the threaded head 5, and the connecting pipe 4 is threadedly connected to the second flange 2 through the threaded groove 6. The fixing mechanism includes a movable sleeve 7. The movable sleeve 7 is movably installed outside the connecting pipe 4. Bolt holes 8 are provided at the four corners of the movable sleeve 7 and the first flange 1. The bolt holes 8 between the movable sleeve 7 and the first flange 1 are fixedly connected through bolts 9. A sealing ring 10 is movably arranged outside the connecting pipe 4 near the threaded head 5. The diameter of the first flange 1 is larger than the diameter of the movable sleeve 7. The diameter of the movable sleeve 7 is larger than the diameter of the sealing ring 10.

[0024] In this embodiment, since standard flange holes 3 with different hole diameters are provided on the first flange 1, different types of safety valves can be tested. In this way, during the experiment, there is no need to prepare a large number of different flanges for matching. Only by adjusting the direction of the safety valve installation hole on the standard flange hole 3 can the efficiency of assembling and debugging the safety valve be effectively improved during the assembling and debugging test process.

[0025] Working principle: When this device is in use, first fix the second flange 2 on the pipeline joint to be tested, then use a fixing part to dock and assemble the second flange 2 with the pipeline joint to be connected. Then thread the threaded groove 6 at one end of the connecting pipe 4 with the middle part of the second flange 2. The threaded head 5 at the other end of the connecting pipe 4 is threaded with the first flange 1 in advance, and the sealing ring 10 is clamped and fixed by the movable sleeve 7 and the first flange 1. Then dock the safety valve to be tested at the end of the first flange 1. During docking, select a suitable standard flange hole 3 according to the installation hole diameter of the safety valve for matching connection to complete the assembly.

[0026] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
