Its function is to control the opening and closing of the ventilation system and the air bleed system, and is used to cut off the working medium in the pipeline. The hydrogen compressor is a compressor used to compress hydrogen and increase its pressure level. The four-stage outlet valve of the M80 hydrogen compressor in the synthesis workshop must be installed from the bottom, and the space for the return position is limited. The valve weighs 19KG, so the existing shut-off valve tooling has poor firmness.

[0003] For example, a shut-off valve tool disclosed in a Chinese utility model patent with a publication number of CN210998449U and an authorization announcement date of July 14, 2020, includes a guide block and a connecting piece, a guide groove is provided on the surface of the guide block, and the guide groove notches of the two guide blocks are relatively buckled and connected into a whole through a connecting piece, so that the two guide grooves cooperate to form a guide hole in the bushing for guiding the sealing section of the shut-off valve sleeve provided with an O-ring and a protective ring, the radial dimension of the inlet end of the guide hole is larger than the maximum outer circle dimension of the protective ring pre-tightened to the annular sealing groove, and the radial dimension of the outlet end of the guide hole is less than or equal to the radial dimension of the inner hole of the bushing and greater than or equal to the radial dimension of the sealing section,

[0004] However, in actual use, the above patent gradually squeezes and limits the O-ring and the protective ring on the shut-off valve through the guide hole, so that the sealing section provided with the O-ring and the protective ring on the shut-off valve is assembled into the bushing from the outlet end of the guide hole, but the tooling has a poor supporting effect on the shut-off valve installed at the bottom of the equipment. Utility Model Content

[0005] The utility model aims to provide a shut-off valve tooling to solve the problem that the existing shut-off valve tooling has a poor supporting effect on the shut-off valve installed at the bottom of the equipment.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-4The utility model provides a technical solution: a shut-off valve tool, including a bushing 1, a sleeve 2 is sleeved on one end of the outer wall of the bushing 1, and support arms 3 are fixedly connected to both ends of the sleeve 2, and a collar 4 is fixedly connected to one end of the support arm 3 away from the bushing 1, and two bolts 5 are threadedly connected to one end of the side wall of the sleeve 2, and the bolts 5 are movably connected to the bushing 1. A tapered opening 6 is provided on the inner wall of the top of the bushing 1, and the tapered opening 6 is smoothly transitioned outwards.

[0021] In this embodiment, a threaded rod for passing the collar 4 is pre-arranged at the fourth-stage outlet valve of the M80 hydrogen compressor. During the installation process, the two collars 4 on the sleeve 2 are first passed through the threaded rod pre-arranged at the fourth-stage outlet valve of the M80 hydrogen compressor, and then the collar 4 is fixed to the hydrogen compressor by a nut, so that the sleeve 2 is fixed, and then the top of the bushing 1 is passed through the sleeve 2 and sleeved on the protective ring on the sealing section of the shut-off valve, so that the protective ring is fixed, wherein a tapered mouth 6 is provided on the inner wall of the top of the bushing 1, so that the bushing 1 can be more easily sleeved on the protective ring, and when the bushing 1 is sleeved on the protective ring, the two bolts 5 on the side wall of the sleeve 2 can be tightened to fix the bushing 1, so that the bushing 1 can support the shut-off valve, thereby improving the firmness of the tooling structure.

[0022] The outer wall of the sleeve 2 is fixedly connected with a reinforcing rib 7 below the support arm 3. In this embodiment, the support arm 3 can be supported by the design of the reinforcing rib 7, thereby increasing the supporting force of the support arm 3 and further improving the supporting force of the tooling.

[0023] Two threaded holes 8 are provided at one end of the side wall of the sleeve 2, and the threaded holes 8 are threadedly connected to the bolts 5. In this embodiment, the threaded holes 8 are provided on the sleeve 2 so that the bolts 5 can be smoothly threadedly connected to the sleeve 2.

[0024] A plurality of limiting grooves 9 are provided at one end of the outer wall of the bushing 1, and the bolt 5 is movably connected to the limiting groove 9. In this embodiment, the limiting groove 9 is designed so that the end of the bolt 5 can be embedded in the limiting groove 9 when being tightened, thereby improving the fixing effect of the bushing 1.

[0025] The bolt 5 is located at one end of the bushing 1 and is fixedly connected to a limiting block 10, and the limiting block 10 is movably connected to the limiting groove 9. In this embodiment, the design of the limiting block 10 allows the end of the bolt 5 to better fit with the limiting groove 9, so that the end of the bolt 5 can be more easily embedded in the limiting groove 9.

[0026] Two handles 11 are fixedly connected to the bottom of the bushing 1. In this embodiment, the design of the handles 11 makes it easier for people to exert force on the bushing 1.

[0027] Working principle: When in use, first pass the two collars 4 on the sleeve 2 through the threaded rods pre-installed at the four-stage outlet valve of the M80 hydrogen compressor, and then fix the collar 4 on the hydrogen compressor through the nut, so that the sleeve 2 is fixed, and then pass the top of the sleeve 1 through the sleeve 2, and sleeve it on the protective ring on the sealing section of the shut-off valve, so as to fix the protective ring. By setting a tapered mouth 6 on the inner wall of the top of the sleeve 1, the bushing 1 can be more easily sleeved on the protective ring. In addition, the design of the handle 11 makes it easier for people to exert force on the bushing 1. When the bushing 1 is sleeved on the protective ring, the two bolts 5 on the side wall of the sleeve 2 can be tightened. During the tightening process of the bolts 5, the limit block 10 at its end will be embedded in the limit groove 9 on the outer wall of the bushing 1, thereby fixing the bushing 1.
