Detailed Implementation
[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] like Figure 1-6 The tool shown is for disassembling and assembling a gas pressure regulating device knife-edge. It includes a main pipe cylinder 1 and a handle 11 perpendicular to the main pipe cylinder 1. Two sets of transverse extension plates 12 are symmetrically arranged on both sides of the end of the main pipe cylinder 1. A locking block 13, which engages with the groove of the gas valve knife-edge seat, is provided at the end of each transverse extension plate 12 away from the main pipe cylinder 1. The knife-edge seat is a component located inside the valve seat for fixing the sealing ring. It has an annular groove at its upper end, and the sealing ring is fitted inside the groove. When it is necessary to inspect the sealing ring, the knife-edge seat must first be removed. Since the knife-edge seat is located inside the valve seat, it is difficult to loosen it by hand. Instead, it requires the use of a slender rod and a hammer to forcefully strike the groove edge of the knife-edge seat to disassemble it. This method is time-consuming, laborious, and prone to damaging components. This device, by setting a main tube 1, allows it to be easily inserted into the valve seat. Then, the locking block 13 at its upper end engages with the groove on the knife-edge seat. By holding the handle 11 and rotating the main tube 1, the knife-edge seat can be easily loosened and removed, improving work efficiency.
[0024] In one embodiment, a first slide groove 2 is provided on the main tube 1, and a limiting slider 21 with a limiting sliding is provided in the first slide groove 2. The handle 11 is provided on the limiting slider 21. By setting the limiting slider 21, the handle 11 can be adjusted up and down within the range of the first slide groove 2, thereby facilitating the removal of the knife seat within different valve seat depths.
[0025] In one embodiment, a support slip ring 22 is provided on the side of the limiting slider 21 away from the grip 11, which slides in contact with the inner wall of the main tube 1. The support slip ring 22 makes the sliding stability of the grip 11 higher, ensuring that it can always be kept perpendicular to the main tube 1, so that the staff can hold it.
[0026] In one embodiment, the main tube 1 is provided with a second groove 3 opposite to the position of the first groove 2. A threaded rod 31 that is movably connected to the support ring 22 is provided in the second groove 3. One end of the threaded rod 31 located inside the support ring 22 is provided with an arc-shaped abutment plate 32 that abuts against the inner wall of the support ring 22. The other end of the threaded rod 31 away from the support ring 22 is threadedly connected with a locking nut 33. After the upper and lower positions of the handle 11 are adjusted, in order to stabilize it in the adjusted position, the locking nut 33 can be rotated to make it abut against the surface of the main tube 1. The tension between the locking nut 33 and the arc-shaped abutment plate 32 is used to clamp the support ring 22 and the main tube 1, so that the handle 11 cannot slide easily.
[0027] In one embodiment, the outer surface of the main tube 1 is provided with abutment plates 4 located on both sides of the second slide groove 3. A rubber strip 41 is provided on the side of the abutment plate 4 opposite to the locking nut 33. By providing the abutment plate 4 and the rubber strip 41, the friction between the locking nut 33 and the main tube 1 is increased, further enhancing the stability effect on the grip rod 11.
[0028] In one embodiment, a limiting annular groove 5 is formed on the inner wall of the end of the main tube 1 away from the transverse extension plate 12. A circular locking plate 51 is slidably engaged in the limiting annular groove 5. A connecting rod 52 extending from the main tube 1 is provided on the circular locking plate 51. A hemispherical hand support plate 53 is provided at the end of the connecting rod 52 away from the circular locking plate 51. The hand support plate 53 is added to ensure the stability of the tool when removing the blade seat. In use, by pressing the hand against the hand support plate 53, pressure is applied to press the tool against the blade seat, so that the locking block 13 will not come out of the groove during the rotation of the main tube 1, thereby improving the removal efficiency.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
