[0007] An arsine gas cylinder valve repair device comprises a ring body and a repair hole arranged in the middle of the ring body. The two ends of the ring body are fixedly connected by bolts. By turning the bolts, the ring body can be driven to extrude the repair hole to change the aperture of the repair hole.
[0008] Preferably, a first deformation groove is provided on one side of the ring body close to the repair hole, and a second deformation groove is arranged between two ends of the ring body.
[0009] Preferably, the large head of the bolt is provided with a handle, and the portion of the handle away from the bolt never contacts the surface of the ring body.
[0010] Preferably, threaded holes are provided at both ends of the ring body, one of the threaded holes passes through the ring body, and the bolt passes through one end of the ring body and is threadedly connected to the threaded hole.
[0011] Preferably, a movable groove is coaxially arranged at one end of the ring body and the threaded hole, and the diameter of the movable groove is larger than the maximum diameter of the handle.
[0012] (III) Beneficial effects
[0013] The utility model has the following beneficial effects:
[0014] The arsine gas cylinder valve repair device has a repair hole arranged in a ring body. When repairing the valve mouth of the arsine gas cylinder, it is only necessary to cover the repair hole on the valve mouth of the gas cylinder, and drive the ring body to squeeze the repair hole by twisting the bolt, so that the valve that has expanded and deformed in the repair hole is squeezed and restored to the original inner diameter. The operation is simple, light and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1 The utility model provides a technical solution: an arsine gas cylinder valve repair device, comprising a ring body 1 and a repair hole 2 arranged in the middle of the ring body 1, the two ends of the ring body 1 are fixedly connected by bolts 5, and the ring body 1 can be driven to squeeze the repair hole 2 by twisting the bolts 5 to change the aperture of the repair hole 2.
[0020] The utility model has a repair hole 2 arranged in the ring body 1. When repairing the valve mouth of the arsine gas cylinder, it is only necessary to cover the repair hole 2 on the valve mouth of the gas cylinder, and drive the ring body 1 to squeeze the repair hole 2 by twisting the bolt 5, so that the valve that has expanded and deformed in the standard mouth is squeezed to restore to the original inner diameter. The operation is simple, light and quick.
[0021] Reference Figure 1 and 2 As shown, in this embodiment, a first deformation groove 3 is provided on one side of the ring body 1 close to the repair hole 2, and a second deformation groove 4 is arranged between the two ends of the ring body 1. In the process of screwing the bolt 5, since the ring body 1 needs to be deformed, the first deformation groove 3 and the second deformation groove 4 can make the ring body 1 more easily produce elastic deformation and have a certain amount of deformation as a whole, which can increase the life of the ring body 1 during cyclic use.
[0022] Reference Figure 1 As shown, in this embodiment, the large head of the bolt 5 is provided with a handle 6, and the portion of the handle 6 away from the bolt 5 never contacts the surface of the ring body 1. Due to the arrangement of the handle 6, the bolt 5 can be manually turned during daily repair, thereby driving the ring body 1 to contract and repair the expanded valve port of the arsine gas cylinder. At the same time, since the portion of the handle 6 away from the bolt 5 never contacts the ring body 1, the ring body 1 can be prevented from interfering with the rotation of the handle 6 during daily rotation of the handle 6.
[0023] Reference Figure 1 and 2 As shown, in this embodiment, threaded holes 8 are provided at both ends of the ring body 1, one of the threaded holes 8 penetrates the ring body 1, and the bolt 5 passes through one end of the ring body 1 and is threadedly connected to the threaded hole 8. By arranging threaded holes 8 at both ends of the ring body 1, the stability of the overall adjustment can be effectively improved when the elastic deformation of the ring body 1 is driven by the bolt 5 to repair the valve port of the arsine gas cylinder, and the thread is not prone to slippage.
[0024] Reference Figure 2 As shown, in this embodiment, one end of the ring body 1 is coaxially arranged with a movable groove 7 with the threaded hole 8, and the diameter of the movable groove 7 is larger than the maximum diameter of the handle 6. In the daily process of screwing the bolt 5, the handle 6 is continuously moved downward. At this time, by arranging the movable groove 7, the stroke of the handle 6 that can be moved downward can be increased, and the handle 6 is prevented from directly contacting the surface of the ring body 1, causing the extrusion wear of the handle 6 and reducing the service life of the handle 6.
