DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0024] The rain shielding device provided in this embodiment is mainly used to solve the problem that the current outdoor gas shut-off valve is set outdoors and is exposed to rain and sun all year round, which will accelerate its aging degree and even affect its shut-off effect. The following technical solutions are provided. Figure 1-Figure 5 Make a detailed description:

[0025] like Figures 1 to 5 As shown, an electric valve rain shielding device comprises: a gas shut-off valve 1 with ventilation pipes 2 at both ends. When in use, the user can disassemble the protective shell 3 and put it on the surface of the gas shut-off valve 1 and then connect them together. The main components of the protective shell 3 are: a first disassembly shell 31 and a second disassembly shell 32, which are both slidably sleeved on the surface of the gas shut-off valve 1. At the same time, semicircular holes 33 are opened on the top and bottom of the first disassembly shell 31 and the second disassembly shell 32. Therefore, after the user connects the first disassembly shell 31 and the second disassembly shell 32 together through the connecting mechanism, a plurality of semicircular holes 33 will be respectively sleeved on the surfaces of the two ventilation pipes 2.

[0026] like Figure 2 and Figure 5 As shown, in some embodiments, the disassembly and assembly mechanism 34 includes two plug-in rings 341 that are fixedly mounted on the surface of the second disassembly and assembly shell 32, two adjustment grooves 342 are provided at one end of the first disassembly and assembly shell 31, and the surfaces of the two plug-in rings 341 are respectively inserted into the inner walls of the two adjustment grooves 342, and also includes an adjustment mechanism 343, and the adjustment mechanism 343 is used to simultaneously adjust the positions of the two plug-in rings 341 on the inner walls of the two adjustment grooves 342, and the adjustment mechanism 343 includes a plurality of mounting blocks 3431 that are respectively fixedly mounted on the surfaces of the first disassembly and assembly shell 31 and the second disassembly and assembly shell 32, and two threaded rods 3432, and the surfaces of the two threaded rods 3432 are respectively threadedly inserted into the surfaces of a plurality of mounting blocks 3431, and the surfaces are both threadedly sleeved with nuts 3433.

[0027] By installing a detachable protective shell 3 on the surface of the gas shut-off valve 1, when in use, the user can fit the disassembled protective shell 3 on the surface of the gas shut-off valve 1 and then assemble them together, so that the protective shell 3 fits on the top of the gas shut-off valve 1, thereby achieving a better protection effect on the gas shut-off valve 1.

[0028] By setting two threaded rods 3432 and fixing two mounting blocks 3431 on the surfaces of the first disassembly shell 31 and the second disassembly shell 32, in the subsequent use process, the user can simultaneously control the positions of the two plug rings 341 on the inner walls of the two adjustment grooves 342 to meet the different diameters of the ventilation duct 2. The two threaded rods 3432 can be threadedly inserted into the surfaces of several mounting blocks 3431 respectively, and then nuts 3433 can be threadedly put on the surfaces of the two threaded rods 3432, thereby realizing the connection between the first disassembly shell 31 and the second disassembly shell 32.

[0029] like Figure 2 and Figure 5 As shown, in some embodiments, a piston head 4 is also included. After the first disassembly shell 31 and the second disassembly shell 32 are connected together, the user needs to slide the surface of the piston head 4 and insert it into the inner walls of the two semicircular holes 33 both arranged above at the same time, so as to prevent rainwater from above from flowing into the internal space of the first disassembly shell 31 and the second disassembly shell 32 from the inside of the two semicircular holes 33. Magnetic sheets 5 are fixedly installed on the surfaces of the piston head 4, the first disassembly shell 31 and the second disassembly shell 32. During installation, several magnetic sheets 5 will be adsorbed together, thereby preventing the piston from loosening on the inner walls of the two semicircular holes 33.

[0030] like Figure 4 As shown, in some embodiments, during specific operations, the user can pull out the baffle plate 6 slidably inserted on the surface of the second disassembly shell 32 to operate the internal gas shut-off valve 1. At the same time, a wire outlet hole 7 is provided on the surface of the second disassembly shell 32. During installation, the user slides the wiring ring 8 into the inner wall of the wire outlet hole 7, and then threads the limit sleeve 9 on the surface of the wiring ring 8 to limit the wiring ring 8 on the inner wall of the wire outlet hole 7. Then, the connecting hose that needs to connect the gas shut-off valve 1 to the external gas leakage detection equipment is passed through the wiring ring 8. At this time, several rubber sheets 10 on the inner wall of the wiring ring 8 will contact the surface of the connecting hose, thereby blocking the remaining space of the wire outlet hole 7.

[0031] The working process of the utility model is as follows: first, the user puts the first disassembly shell 31 and the second disassembly shell 32 on the surface of the gas shut-off valve 1, so that the inner walls of the first disassembly shell 31 and the second disassembly shell 32 are both in contact with the surface of the gas shut-off valve 1, and then the two threaded rods 3432 are respectively threadedly inserted into the surfaces of several mounting blocks 3431, so that the first disassembly shell 31 and the second disassembly shell 32 can be installed.

[0032] Secondly, during subsequent use, if it is necessary to perform relevant operations on the gas shut-off valve 1, the baffle 6 can be slid out, and the interior of the second disassembly shell 32 will be exposed within the user's operating range. The subsequent user can perform relevant operations on the gas shut-off valve 1 without dismantling the first disassembly shell 31 and the second disassembly shell 32.
