Claims5
A self-locking valve, comprising:
- a valve body, comprising:
- an upper box body;
- a lower box body coupled to and in communication with a lower end of the upper box body;
- a water inlet pipe coupled to and in communication with a left end of the lower box body;
- and
- a water outlet pipe coupled to and in communication with a right end of the lower box body;
- a valve element slidingly coupled within the upper box body and the lower box body, the valve element comprising:
- a rectangular core body;
- a threaded through hole through the rectangular core body along a longitudinal axis thereof, the threaded through hole extending from a top surface thereof to a bottom surface thereof;
- an upper positioning inserting groove in a right side face of the rectangular core body proximate the top surface thereof;
- and
- a lower positioning inserting groove in the right side face of the rectangular core body proximate the bottom surface thereof a valve control assembly, extending through an aperture through a top surface of the upper box body and rotatably coupled to a lower surface of the lower box body, wherein
- the valve control assembly is rotatable with respect to the valve body, the valve control assembly comprising:
- a screwing rod configured for a user to rotate the valve control assembly by rotating the screwing rod;
- a threaded control rod corresponding to and threaded through the threaded through hole of the valve element, wherein the valve element slides relative to the valve body in response to rotation of the valve control assembly;
- and
- a worm gear coupled to and concentric with the valve control assembly, the worm gear being disposed exterior to the valve body;
- an upper locking assembly coupled to the top surface of the upper box body and operationally coupled to the worm gear of the valve control assembly, wherein the upper locking assembly slidingly engages a right side of the upper box body in response to rotation of the valve control assembly in a first direction to stop further rotation of the valve control assembly in the first direction and disengages the right side of the upper box body in response to rotation of the valve control assembly in a second direction;
- and
- a lower locking assembly coupled to and in communication with the lower box body.
