[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] Referring to Figures 1-4 , a water receiving valve that is convenient for installation includes a pipeline 1. A second semi-circular clamping ring 3 is arranged on the outer side of the pipeline 1. A first semi-circular clamping ring 2 is arranged at the bottom end of the second semi-circular clamping ring 3. The second semi-circular clamping ring 3 and the first semi-circular clamping ring 2 are rotationally connected through a hinge. The top end of the second semi-circular clamping ring 3 is fixedly connected to a water receiving valve body 7. A quick-release bolt 4 is arranged between the first semi-circular clamping ring 2 and the second semi-circular clamping ring 3. A locking nut 9 is threadedly connected to the outer side of the quick-release bolt 4. Anti-slip sheets 5 are sleeved at both ends of the outer side of the quick-release bolt 4. The anti-slip sheets 5 are respectively in contact with the outer sides of the first semi-circular clamping ring 2 and the second semi-circular clamping ring 3. During installation, the pipeline 1 is inserted between the first semi-circular clamping ring 2 and the second semi-circular clamping ring 3. The polyurethane sealing gasket 17 will closely fit the outer wall of the pipeline 1. Then, the water receiving valve body 7 is quickly fixed on the pipeline 1 through a locking device. The first semi-circular clamping ring 2 and the second semi-circular clamping ring 3 can form a complete clamp state, and the locking device of the clamp adopts the quick-release bolt 4 and the locking nut 9. By rotating the quick-release bolt 4 and the locking nut 9, the quick locking and loosening of the clamp can be realized, further improving the installation and disassembly efficiency.

[0030] Referring to Figure 1, a positioning mechanism is provided between the semi-circular snap ring II 3 and the pipe 1. The positioning mechanism includes two positioning protrusions 12 fixedly connected to the inner wall of the semi-circular snap ring II 3. Positioning grooves 14 that cooperate with the positioning protrusions 12 are provided inside the pipe 1. The positioning protrusions 12 are all engaged with the positioning grooves 14. Through the cooperation of the positioning protrusions 12 and the positioning grooves 14, the water receiving valve body 7 can be quickly and accurately installed.

[0031] Refer to Figure 2 , an anti-corrosion mechanism is provided on the outer side of the semi-circular snap ring I 2. The anti-corrosion mechanism includes an internal thread ring 10 provided inside the semi-circular snap ring I 2 and surrounding the lock nut 9. An anti-corrosion cover 6 is threadedly connected inside the internal thread ring 10. When the water receiving valve body 7 is firmly installed on the pipe 1, the anti-corrosion cover 6 can be screwed into the internal thread ring 10. Furthermore, an anti-corrosion cover 6 with a protective function can be added outside the lock nut 9. Through the setting of the anti-corrosion cover 6, the erosion of the lock nut 9 by external rainwater and sediment can be reduced, and the situation where it cannot be disassembled due to the rusting of the lock nut 9 can be reduced.

[0032] Refer to Figure 4 , a stabilizing mechanism is provided between the semi-circular snap ring II 3 and the pipe 1. The stabilizing mechanism includes iron blocks 16 all embedded inside the positioning grooves 14. Magnets 13 that cooperate with the iron blocks 16 are fixedly connected to the bottom ends of the positioning protrusions 12. The magnets 13 are adsorbed to the iron blocks 16. Through the cooperation of the magnets 13 and the iron blocks 16, on the basis of the fastening of the clamp, the connection relationship between the semi-circular snap ring II 3 and the pipe 1 can be increased, so that the water receiving valve body 7 can be firmly installed above the pipe 1.

[0033] Refer to Figure 3 , a water outlet pipe 8 is fixedly connected to the top of the water receiving valve body 7. An inlet pipe 11 is fixedly connected to the bottom end of the water receiving valve body 7 and between the two positioning protrusions 12. An inlet port 15 that cooperates with the inlet pipe 11 is provided inside the semi-circular snap ring II 3. The bottom end of the inlet pipe 11 extends into the pipe 1. Through the setting of the inlet port 15, it is convenient for the staff to insert the semi-circular snap ring II 3 into the pipe 1.

[0034] Refer to Figure 4 , polyurethane sealing gaskets 17 are fixedly connected to the inner walls of both the pipe 1 and the semi-circular snap ring I 2. Anti-slip patterns are provided on the surfaces of the polyurethane sealing gaskets 17. By adding anti-slip patterns on the surfaces of the polyurethane sealing gaskets 17, the friction with the outer wall of the pipe 1 can be enhanced, and the loosening phenomenon after long-term use can be prevented.

[0035] Refer to Figure 2 and Figure 3, the inner wall of the water inlet 15 and the outer side of the water inlet pipe 11 are both coated with a sealing waterproof coating. A rotating ring is fixedly connected to the bottom of the corrosion prevention cover 6. By using the sealing waterproof coating, the sealing performance between the water inlet pipe 11 and the water inlet 15 in the semi-circular clamping ring 1 can be increased, and the leakage of the conveyed water body from the joint can be avoided.

[0036] Working principle: First, during installation, insert the pipe 1 between the semi-circular clamping ring 1 and the semi-circular clamping ring 2. The polyurethane sealing gasket 17 will closely fit the outer wall of the pipe 1. Then, quickly fix the water receiving valve body 7 on the pipe 1 through the locking device. The semi-circular clamping ring 1 and the semi-circular clamping ring 2 can form a complete clamp state, and the locking device of the clamp uses quick-release bolts 4 and locking nuts 9. By rotating the quick-release bolts 4 and locking nuts 9, the quick locking and loosening of the clamp can be realized, further improving the installation and disassembly efficiency. And through the cooperation of the magnetic block 13 and the iron block 16, the connection relationship between the semi-circular clamping ring 2 and the pipe 1 can be increased on the basis of the clamp fastening, so that the water receiving valve body 7 can be firmly installed above the pipe 1. When the water receiving valve body 7 is firmly installed on the pipe 1, the corrosion prevention cover 6 can be screwed into the internal thread ring 10, and thus a corrosion prevention cover 6 with a protection function can be added outside the locking nut 9. Through the setting of the corrosion prevention cover 6, the erosion of the locking nut 9 by external rainwater and sediment can be reduced, and the situation of being unable to disassemble due to rust inside the locking nut 9 can be reduced. And by adding anti-slip patterns on the surface of the polyurethane sealing gasket 17, the friction with the outer wall of the pipe 1 can be enhanced, preventing loosening after long-term use.
