[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a valve protection device, including an upper protective shell 1 and a lower protective shell 2 disposed on the upper and lower sides of the valve. The upper protective shell 1 and the lower protective shell 2 are fixed together by an installation assembly. The installation assembly includes a first mounting seat 7 fixedly installed at the four corners of the inner cavity of the upper protective shell 1. A second mounting seat 8 is fixedly connected to each of the four corners of the inner cavity of the lower protective shell 2. An installation rod 9 is provided at the four corners of the top of the upper protective shell 1. The bottom end of the installation rod 9 passes through the upper protective shell 1 and the first mounting seat 7 in sequence and extends to the bottom of the first mounting seat 7 and is threadedly connected to the top of the second mounting seat 8.

[0022] In this embodiment, the upper protective shell 1 and the lower protective shell 2 are used together to protect the main body of the valve. During installation, the upper protective shell 1 and the lower protective shell 2 are located on the upper and lower sides of the valve, respectively, and they fit tightly together. Then, the user can pass the bottom end of the mounting rod 9 through the upper protective shell 1 and the first mounting seat 7 in sequence and tighten it to the top of the second mounting seat 8, thereby installing and fixing the upper protective shell 1 and the lower protective shell 2 on the outside of the valve for its protection.

[0023] Both the surface of the upper protective shell 1 and the surface of the first mounting base 7 are provided with through holes 10 that are adapted to the mounting rod 9, and the bottom end of the mounting rod 9 is inserted into the inner cavity of the through hole 10. The through hole 10 provides space for the mounting rod 9 to be inserted and installed.

[0024] Preferably, upper protective plate 3 and lower protective plate 4 are installed on both sides of the upper protective shell 1 and the lower protective shell 2, respectively. The upper protective plate 3 and lower protective plate 4 are respectively located on the upper and lower sides of the valve and pipeline connection. The upper protective plate 3 and lower protective plate 4 are fixed together by a positioning assembly. The positioning assembly includes a first connecting plate 11 fixedly installed on both sides of the upper protective plate 3, and a second connecting plate 12 fixedly installed on both sides of the lower protective plate 4. The first connecting plate 11 and the second connecting plate 12 are locked together by a locking assembly. The locking assembly includes a locking rod 13 located above the first connecting plate 11. The bottom end of the locking rod 13 passes through the first connecting plate 11 and the second connecting plate 12 in sequence and extends to the bottom of the second connecting plate 12. The bottom end of the locking rod 13 is threadedly connected to a locking nut 14, and the top of the locking nut 14 is in contact with the bottom of the second connecting plate 12.

[0025] In this embodiment, the upper protective plate 3 and the lower protective plate 4 are arc-shaped pieces that fit snugly at the connection between the valve and the pipeline. During installation, the first connecting plate 11 and the second connecting plate 12 on both sides of the upper protective plate 3 and the lower protective plate 4 fit together. At this time, the user can insert the locking rod 13 through the first connecting plate 11 and the second connecting plate 12, and then tighten the locking nut 14 at the bottom of the locking rod 13 to lock the first connecting plate 11 and the second connecting plate 12 together, thereby installing and fixing the upper protective plate 3 and the lower protective plate 4 at the connection between the valve and the pipeline.

[0026] It is worth noting that a fixed shell 5 is fixedly installed on the top of the upper protective shell 1, and a pull cover 6 is provided on the top of the fixed shell 5. An elastic connection assembly is provided between the pull cover 6 and the fixed shell 5. The elastic connection assembly includes two sets of first fixing plates 15 fixedly installed on one side of the fixed shell 5. A hinge shaft 16 is fixedly installed on the inner side of the two sets of first fixing plates 15. Two sets of second fixing plates 17 are rotatably connected to the surface of the hinge shaft 16. One side of the second fixing plate 17 is fixedly connected to one side of the pull cover 6. A torsion spring 18 is sleeved on the surface of the hinge shaft 16. The two sets of support legs of the torsion spring 18 are respectively attached to the surfaces of the pull cover 6 and the fixed shell 5.

[0027] With the pull cover 6, the user can open the pull cover 6 to operate the valve. When the pull cover 6 is opened, the pull cover 6 will rotate around the hinge shaft 16. Its rotation will twist the torsion spring 18 to store force. After the valve operation is completed, the user can release the pull cover 6. At this time, the reaction force generated by the twisting of the torsion spring 18 will push the pull cover 6 to rotate and return to its original position.

[0028] Furthermore, a support plate 19 is fixedly installed on one side of the inner cavity of the fixed shell 5, and the bottom of the pull cover 6 is attached to the top of the support plate 19. The support plate 19 can limit and support the pull cover 6, preventing it from tilting into the fixed shell 5.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
