[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve that can be used for on-off control of low-pressure pipeline media. A butterfly valve is a valve whose closing member (valve disc or butterfly plate) is a disc that rotates around the valve shaft to open and close.

[0003] The current butterfly valve is not equipped with a protective structure during installation, and is usually installed in an exposed installation method. Since it is exposed to the outside, non-staff and criminals can also operate it on and off. Switching that does not comply with regulations can easily cause damage to the pipe body and the equipment connected to it, resulting in unnecessary losses. In addition, the exposed butterfly valve is easily affected by external forces such as collisions, and the effectiveness of the butterfly valve cannot be guaranteed. In view of this, there may be technical means to solve the above problems in the existing technology, but this case intends to provide an alternative or replacement technical solution.

[0018] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0019] Example: See Figure 1-3 A protective butterfly valve comprises a butterfly valve body 1 and two pipe bodies 2. The two pipe bodies 2 are respectively mounted on both sides of the butterfly valve body 1 through flanges. A protective structure is installed at the lower end of the butterfly valve body 1.

[0020] The protective structure includes: a bottom plate 3, two support blocks 4, four mounting rods 5, a protective box 6, a top plate 7 and an operation locking assembly;

[0021] The bottom plate 3 is located at the lower end of the butterfly valve body 1, the two support blocks 4 are respectively installed on both sides of the upper end of the bottom plate 3, and are respectively located at the lower ends of the two tube bodies 2, the four mounting rods 5 are respectively installed on both sides of the upper ends of the two support blocks 4, the protective box body 6 is fixedly installed on the upper ends of the four mounting rods 5, the top plate 7 is installed on the upper end of the protective box body 6 by bolts, and the operating locking assembly is located on one side of the protective box body 6 and is connected to the butterfly valve body 1.

[0022] When installing the butterfly valve body 1, first place the base plate 3 in the designated position, and use the flange to pass the two pipe bodies 2 through the two sides of the protective box 6 and install them on both sides of the butterfly valve body 1. Then, support the two pipe bodies 2 through the two support blocks 4 at the upper end of the base plate 3, and protect the butterfly valve body 1 through the protective box 6 at the upper end of the four mounting rods 5. Then, connect one end of the operating locking assembly to the operating handle of the butterfly valve body 1, and lock the operating handle of the butterfly valve body 1 to prevent non-staff from operating it incorrectly.

[0023] In the specific implementation process, the operation locking assembly includes: an operation hole 8, a connecting sleeve 9, a connecting rod 10, an operation ring 11, a locking frame 12 and a locking ring 13;

[0024] The operating hole 8 is opened at the front end of the protective box 6, one end of the connecting sleeve 9 is connected to the driving end of the butterfly valve body 1, one end of the connecting rod 10 is movably embedded in the connecting sleeve 9, the operating ring 11 is fixedly installed on one side of the connecting rod 10, and the locking frame 12 is fixedly installed on the upper end of the front wall of the protective box 6. The locking ring 13 is movably sleeved on the upper end of the operating ring 11, and one end is movably embedded in the locking frame 12.

[0025] When the butterfly valve needs to be operated, the lock heads in the locking holes 14 on both sides of the locking frame 12 and the locking ring 13 are removed, and the locking ring 13 is taken out from the locking frame 12 and the operating ring 11 to release the limit on the operating ring 11. By rotating the operating ring 11, under the connection between the connecting rod 10 and the connecting sleeve 9, the operating handle of the butterfly valve body 1 is rotated to realize the switching of the butterfly valve body 1. Since the connecting rod 10 and the connecting sleeve 9 are movably plugged in, a single operating ring 11 can be used to operate multiple butterfly valves of the same batch. After the switching of the butterfly valve body 1 is completed, the locking ring 13 can be installed on the upper end of the operating ring 11 and embedded in the locking frame 12. Then the lock head is embedded in the locking holes 14 on both sides of the locking frame 12 and the locking ring 13 to limit the rotation of the operating ring 11.

[0026] In a specific implementation process, locking holes 14 are formed on both sides of the locking frame 12 and the locking ring 13 .

[0027] In a specific implementation process, two support rods 15 are provided between the butterfly valve body 1 and the bottom plate 3 .

[0028] In the specific implementation process, an arc-shaped groove is opened on the top of the support block 4.

[0029] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
