AI Technical Summary
When using existing angle valves, water tends to remain on the inner wall of the valve body after the water flow changes direction, causing dripping after closing and resulting in water waste.
A self-closing angle valve was designed. By embedding a self-closing structure in the outlet pipe, the water flow pressure pushes the sealing block down and exposes the discharge pipe. After the drainage is completed, the spring pushes the sealing block back to re-close the discharge pipe and prevent dripping.
It effectively prevents water residue after drainage, reduces waste, avoids dripping, and improves water resource utilization efficiency.

[0018] Referring to Figs. 1-3The technical scheme adopted in the embodiment is shown as follows: a self-closing angle valve, comprising a water inlet pipe 1 and a valve seat 3 arranged on one side of the water inlet pipe 1, a water outlet pipe 2 fixedly connected to the lower surface of the valve seat 3, a rotating valve core 4 arranged in the valve seat 3 and penetrating the valve seat 3, a self-closing structure 7 embedded in the inner wall of the bottom of the water outlet pipe 2, the self-closing structure 7 comprising a contraction block 21 embedded in the inner wall of the bottom of the water outlet pipe 2 and a middle shaft 22 integrally formed at the center of the contraction block 21, a T-shaped discharge pipe 23 integrally formed in the middle shaft 22 and penetrating the bottom of the middle shaft 22, a blocking block 25 slidably arranged between the middle shaft 22 and the inner wall of the contraction block 21, the blocking block 25 comprising a body block 31 arranged between the middle shaft 22 and the inner wall of the contraction block 21 and a guide slope block 33 fixedly arranged on the top of the body block 31, a limiting piece 27 arranged on the inner wall of the contraction block 21, and a spring 26 arranged between the top surface of the limiting piece 27 and the bottom surface of the blocking block 25. In use, the water inlet pipe 1 of the angle valve is arranged in an external pipeline, so that water flows into the water inlet pipe 1 through the external pipeline, and the water outlet pipe 2 is connected to another external pipeline, so that water flows out of the water outlet pipe 2 after passing through the angle valve, thereby connecting the two external pipelines. When water needs to be supplied, the rotating valve core 4 on the valve seat 3 is rotated, the rotating valve core 4 is a rotating shaft and a spherical valve core structure, and then the rotating valve core 4 is rotated, so that the rotating shaft and the spherical valve core rotate in the valve seat 3, thereby controlling whether water can pass through the angle valve. During water drainage, water flows into the contraction block 21 of the self-closing structure 2 through the water outlet pipe 2, pushes the blocking block 25 downward by water pressure, and pushes the spring 26 to generate elastic force. When the blocking block 25 is lowered to a certain extent, the end of the T-shaped discharge pipe 23 is exposed, the blocking block no longer blocks the discharge pipe 23, water flows into the discharge pipe 23, and the water flows out of the discharge pipe 23. The guide slope block 33 guides the water flow into the discharge pipe 23. After water drainage is completed, the spring 26 pushes the blocking block 25 back, the blocking block 25 moves upward and re-closes the discharge pipe 23, and then the residual water in the water outlet pipe 2 does not continue to flow out, thereby reducing waste and preventing dripping.
