Description

Technical Field

[0001] The utility model relates to the technical field of pipeline water outlets, in particular to a water outlet. Background Art

[0002] A bypass valve is usually provided at the output end of the main water pipe, and the bypass valve is used to connect to an external water pipe. However, when the existing external water pipe is connected to the output end of the bypass valve, it is necessary to use a clamp to lock it, which is more troublesome to operate, or it is directly connected by an expansion sleeve, which is very susceptible to water pressure shock and causes the external water pipe to separate from the bypass valve. Therefore, the existing water outlet needs to be improved.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN219932432U is conducive to maintaining the water pump outlet joint by providing a plug and a connecting component, and the water outlet or water inlet is tightly connected to the delivery pipeline.

[0004] However, the device still has shortcomings: when the structure is connected to the external water pipe, the external water pipe is still connected to the water outlet by direct plugging, which causes the external water pipe to separate from the connecting component due to high pressure at the moment the valve disc opens.

A sealing ring is provided in the water guide pipe between the water outlet hole and its input end. The valve flap is located in the water guide pipe and is slidably connected to its inner wall. The valve rod is screwed to the valve cover. One end of the valve rod inserted into the water guide pipe is rotatably connected to the valve flap. One end of the valve rod extending out of the valve body is connected to a handwheel. The flange is connected to the water guide pipe.

[0011] Preferably, the water guide pipe is provided with an annular groove A coaxial with its water inlet at one end. A circular ring is integrally connected to the inner wall of the flange. The circular ring is located in the annular groove A and is slidably connected to its inner wall.

Detailed implementation manners

[0025] Embodiment 1

[0026] Such as Figures 1 - 6As shown in the figure, a water outlet proposed by the present utility model includes a valve body, a water outlet pipe 9, a flexible locking ring 12, and a driving assembly. The valve body includes a water guide pipe 1, a valve flap 4, a valve rod 5, and a flange 6. An outlet hole 102 communicating with its interior is provided on the water guide pipe 1. The outlet hole 102 is coaxial with the water outlet pipe 9. A valve cover 2 is provided at the top end of the water guide pipe 1, and a sealing ring 3 is provided in the water guide pipe 1 between the outlet hole 102 and its input end. The valve flap 4 is located inside the water guide pipe 1 and is slidably connected to its inner wall. The valve rod 5 is helically connected to the valve cover 2. One end of the valve rod 5 inserted into the water guide pipe 1 is rotatably connected to the valve flap 4, and one end of the valve rod 5 extending out of the valve body is connected to a handwheel. The flange 6 is connected to the water guide pipe 1. A fixing rod 8 is provided on the water guide pipe 1. A cylindrical channel 81 coaxial with it is provided inside the fixing rod 8, and an annular groove B82 coaxial and communicating with the cylindrical channel 81 is provided inside the fixing rod 8. An annular groove C91 coaxial with it is provided on the outer wall of the water outlet pipe 9. The water outlet pipe 9 is arranged inside the fixing rod 8 and is coaxial with the cylindrical channel 801. The input end of the water outlet pipe 9 communicates with the outlet hole 102. An annular insertion pipe channel is provided between the outer wall of the water outlet pipe 9 and the inner wall of the cylindrical channel 801. The flexible locking ring 12 is located in the annular groove B802 and corresponds to the annular groove C91. An annular groove D121 coaxial with it is provided on the outer arc surface of the flexible locking ring 12. A spring 13 coaxial with it is sleeved on the flexible locking ring 12. The spring 13 is located in the annular groove D121, and both ends of the spring 13 are respectively abutted against both sides of the annular groove D121. The inner diameter of the flexible locking ring 12 in the relaxed state is not less than the outer diameter of the annular insertion pipe channel. The driving assembly is connected to the fixing rod 8 and includes a hollow threaded pipe 14. The hollow threaded pipe 14 is inserted into the annular groove B82 at one end of the fixing rod 8 away from the valve body. The hollow threaded pipe 14 is helically connected to the fixing rod 8, and the inner diameter of the hollow threaded pipe 14 is not less than the outer diameter of the annular insertion pipe channel. One end of the hollow threaded pipe 14 inserted into the annular groove B82 is rotatably connected to an annular pad 15. The annular pad 15 abuts against one end of the flexible locking ring 12 away from the valve body. The driving assembly squeezes the flexible locking ring 12 in the working state, so that the flexible locking ring 12 contracts and deforms inward and locks the external connecting pipe on the water outlet pipe 9.

[0027] In this embodiment, when connecting an external water pipe, the external water pipe is sleeved on the water outlet pipe 9 along the annular insertion pipe channel. Then, the hollow threaded pipe 14 is rotated. The hollow threaded pipe 14 gradually penetrates into the annular groove B82. The annular pad 15 rotatably connected to its end gradually squeezes the flexible locking ring 12. The flexible locking ring 12 deforms and contracts towards the water outlet pipe 9. The contracted flexible locking ring 12 presses the external pipe tightly and presses its waist into the annular groove D121, effectively improving the sealing performance between the external pipe and the water outlet pipe 9. At the same time, it can also effectively prevent the external water pipe from separating from the water outlet pipe 9 under the instantaneous impact of water flow. When the external pipe needs to be disassembled, the hollow threaded pipe 14 is rotated in the reverse direction. At this time, the flexible locking ring 12 gradually returns to its relaxed state under the tension of the spring 13, and the external pipe can be easily pulled out.

[0028] Embodiment 2

[0029] As Figures 1 - 3 shown, for a water outlet proposed by the present utility model, compared with Embodiment 1, an annular groove A101 coaxial with it is provided at one end of the water guide pipe 1 at its water inlet. A circular ring is integrally connected to the inner wall of the flange 6. The circular ring is located in the annular groove A101 and is slidably connected to its inner wall. A locking knob 7 for restricting the relative rotation between it and the water guide pipe 1 is spirally arranged on the arc surface of the flange 6.

[0030] In this embodiment, when installing the valve body, the flange 6 is in a freely rotatable state. After adjusting the outlet orientation of the water outlet pipe 9, turn the locking knob 7 to lock the flange 6 and the water guide pipe 1 to prevent the water guide pipe 1 from rotating.

[0031] Embodiment 3

[0032] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, for a water outlet proposed by the present utility model, compared with Embodiment 1, a connecting pipe 10 is provided at the output end of the water outlet pipe 9 and is spirally connected to it. A filter screen 11 is provided at one end of the connecting pipe 10 away from the water outlet pipe 9, and the outer diameter of the connecting pipe 10 is not greater than the outer diameter of the water outlet pipe 9.

[0033] In this embodiment, the filter screen 11 is used to intercept larger - sized impurities in the water. When it is necessary to clean the filter screen 11, first close the water outlet hole 102 of the valve body, then remove the external pipeline, and then rotate the connecting pipe 10 to remove it to clean the filter screen 11.

[0034] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to this. Within the scope of knowledge possessed by those skilled in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
