[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme. A highly wear-resistant valve steel includes a support placement frame and a valve steel body. A fixed rod is fixedly connected to the inner cavity side wall of the support placement frame. A threaded rod and a hand crank are provided on the other side wall of the support placement frame. The opposite ends of the threaded rod and the fixed rod are both fixedly connected with clamping plates. Anti-slip convex strips are fixedly connected to the opposite side walls of the two clamping plates. A protection component is provided outside the valve steel body. The protection component includes two protection shells. Rubber protection pads are fixedly connected to the inner cavity walls of the two protection shells. Two first mounting blocks and two second mounting blocks are respectively fixedly connected to the central positions of the upper and lower walls of the two protection shells. First insertion blocks are fixedly connected to the walls of the two first mounting blocks. Second slots that are respectively matched with the first insertion blocks are opened on the two second mounting blocks.

[0006] Preferably, a slot is opened at the bottom of the support placement frame. A fixed frame is fixedly connected to the bottom of the support placement frame.

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 work shall fall within the protection scope of the present invention.

[0023] Embodiment: A highly wear-resistant gas valve steel, as Figures 1-3 shown, includes a support placement rack 1. The overall structure of the support placement rack 1 is a "U" shape. A groove 4 is opened at the bottom of the support placement rack 1. A "C" - shaped fixed frame 2 is fixedly connected to the center position at the bottom of the support placement rack 1. A hydraulic cylinder 3 is fixedly connected to the bottom of the center position of the inner cavity of the fixed frame 2. The extending end of the hydraulic cylinder 3 is fixedly connected to a support placement plate 31. A cylindrical fixed rod 5 is fixedly connected to the center position of the inner cavity side wall of the support placement rack 1. A threaded rod 7 is threadedly connected to the position corresponding to the fixed rod 5 on the other side wall of the support placement rack 1. Both ends of the threaded rod 7 and the fixed rod 5 facing each other are fixedly connected with clamping plates 6. A plurality of anti - slip convex strips 61 are fixedly connected to the side walls of the two clamping plates 6 facing each other. One end of the support placement plate 31 close to the fixed rod 5 is located in the inner cavity of the left clamping plate 6. The end of the threaded rod 7 far from the fixed rod 5 is fixedly connected with a hand crank handle 71.

[0024] There is a valve steel body 8 in the middle of two clamping plates 6. The outer wall surface of the valve steel body 8 is electroplated with a wear-resistant coating 81. The wear-resistant coating 81 is a hard alloy, and the hard alloy coating is usually composed of hard materials such as tungsten carbide or titanium carbide, which has extremely high hardness and wear resistance and is suitable for occasions with extremely high requirements for wear resistance. There is a protection component 9 outside the valve steel body 8. The protection component 9 includes two protection shells 91 clamped on the outside of the valve steel body 8. The protection shells 91 are arc-shaped structures. Rubber protection pads 92 are fixedly connected to the inner cavity wall surfaces of the two protection shells 91. First mounting blocks 93 are fixedly connected to the central positions of the upper and lower wall surfaces of one side protection shell 91. First insertion blocks 94 are fixedly connected to the wall surfaces of the two first mounting blocks 93 close to the valve steel body 8. The two first insertion blocks 94 are in an inverted "T" shape. Second mounting blocks 95 are fixedly connected to the positions corresponding to the first mounting blocks 93 on the upper and lower wall surfaces of the other side protection shell 91. Second slots 96 that cooperate with the first insertion blocks 94 respectively are opened on the two second mounting blocks 95.

[0025] The working principle of the present utility model:

[0026] When in use, by placing the valve steel body 8 between the two clamping plates 6 and shaking the hand crank 71 to drive the other clamping plate 6 to approach the end of the valve steel body 8 to clamp the valve steel body 8. By clamping the two protection shells 91 on both sides of the valve steel body 8, at this time, the first insertion block 94 on one side protection shell 91 approaches the second slot 96 on the second mounting block 95 on the other side until the first insertion block 94 is clamped into the inner cavity of the second slot 96. The rubber protection pads 92 in the inner cavities of the two protection shells 91 can protect the valve steel body 8. When the valve steel body 8 needs to be used, just move the two protection shells 91 away from each other to release the protection of the outer wall surface of the valve steel body 8.

[0027] When in use, by placing the valve steel body 8 on the support placement plate 31 and starting the hydraulic cylinder 3 to drive the valve steel body 8 on the support placement plate 31 to rise and fall. When the valve steel body 8 reaches the appropriate height, the hand crank 71 can be shaken to clamp the end of the valve steel body 8 with the clamping plate 6, which can save manpower.
