[0060] The lower surface of the rubber sealing ring block 23 is in a semispherical shape, and the rubber sealing ring block 23 is fixedly sleeved on the inner wall of the fixed pipe 7.

[0061] Further, the connecting water pipe 16 is slidingly sleeved in the fixed pipe 7.

[0062] The two fixed grooves 11 are arranged on the outer surfaces of the left and right sides of the fixed pipe 7, and the fixed grooves 11 extend into the fixed pipe 7.

[0063] The two positioning blocks 15 are fixedly connected to the outer surface of the fixed pipe 7.

[0076] Further, the connecting water pipe 16 in the present scheme refers to the water pipe that needs to be installed with the explosion-proof angle valve 1 in actual installation.

[0077] In the initial state, the spring 18 is always in the stretched state, and the fixed rod 19 is located on the upper side of the positioning hole 14. In use, the fixed pipe 7 is sleeved outside the connecting water pipe 16, so that the upper end of the connecting water pipe 16 is in close contact with the lower surface of the rubber sealing ring block 23. At this time, the sliding ring 10 is pushed downward, so that the sliding ring 10 moves downward. The sliding ring 10 extrudes the two rotating plates 13 during the downward movement, so that the two rotating plates 13 relatively rotate, and then drive the two extrusion blocks 12 to relatively extrude the outer surface of the fixed pipe 7, and then fix the fixed pipe 7. When the sliding ring 10 moves downward, when the fixed rod 19 moves downward to the position of the positioning hole 14, under the action of the release force of the spring 18 and the release force of the fixed rod 19, the fixed rod 19 is pushed to slide into the positioning hole 14, thereby fixing the sliding ring 10 and the extrusion block 12, and then fixing the connecting water pipe 16. It is convenient to fix, and when disassembling, only the fixed plate 17 needs to be pulled out, which is convenient to disassemble, fast to install, labor-saving, high in installation efficiency, and high in practicality of the explosion-proof angle valve.

[0078] Further, after the explosion-proof angle valve 1 and the connecting water pipe 16 are installed, the explosion-proof angle valve 1 can be rotated, thereby driving the water inlet pipe 3 to rotate, and then synchronously driving the water outlet pipe 2 to rotate, thereby adjusting the orientation angle of the water outlet pipe 2, and making the explosion-proof angle valve 1 more practical and flexible.

[0079] Furthermore, in this design, the rotating ring 21 is rotatably connected to the inner cavity 22. On the one hand, this can increase the seal between the sealing hemisphere 6 and the inlet pipe 3. On the other hand, it can also ensure the connection between the inlet pipe 3 and the sealing hemisphere 6, so that the sealing hemisphere 6 and the inlet pipe 3 can only rotate relative to each other and cannot be separated from each other, thereby ensuring the practicality of the explosion-proof angle valve 1.

[0080] Furthermore, in this design, the sliding connection between the sealing ring 4 and the sealing groove 5 can increase the contact area between the sealing hemisphere 6 and the inlet pipe 3, thereby improving the sealing performance between the sealing hemisphere 6 and the inlet pipe 3 and increasing the practicality of the explosion-proof angle valve 1.

[0081] Working principle: When this device is in use, the connecting water pipe 16 in this solution refers to the water pipe that needs to be installed with the explosion-proof angle valve 1 in actual installation;

[0082] Initially, spring 18 is always under tension, and fixing rod 19 is located above positioning hole 14. In use, fixing tube 7 is fitted over connecting water pipe 16, so that the upper end of connecting water pipe 16 is tightly against the lower surface of rubber sealing ring block 23. Then, sliding ring 10 is pushed downwards, causing it to move downwards. During this downward movement, sliding ring 10 presses against two rotating plates 13, causing them to rotate relative to each other. This, in turn, causes two pressing blocks 12 to press against the outer surface of fixing tube 7, thus pressing the fixing tube 7. When the sliding ring 10 moves downward, and the fixing rod 19 moves downward to the position of the positioning hole 14, the fixing rod 19 is pushed into the positioning hole 14 by the release force of the spring 18 and the fixing rod 19, thereby fixing the sliding ring 10, the pressing block 12, and the connecting water pipe 16. The fixing is convenient, and the disassembly only requires pulling out the fixing plate 17. The disassembly is convenient, the installation is quick and easy, and the installation is labor-saving and efficient, thereby increasing the practicality of the explosion-proof angle valve.
