In the prior art, the liquid valve is usually made of a metal material, and mainly includes three types of structures: a gate valve, a disc valve, and a ball valve. The publication No. CN2926700Y discloses a novel alcohol guiding valve, comprising a valve body, wherein the valve body is composed of left and right chambers connected to each other, and a water inlet is opened at one end of the left chamber, and one end of the right chamber is opened. The outlet water is formed with an opening in the right chamber corresponding to the other end of the water outlet, and a bowl type rubber sealing plug, a handle and a cover are respectively installed in the right chamber between the opening and the outlet water, and are in a sealed state The plug of the bowl type rubber sealing plug is stuck on the water, and the head sleeve of the handle is engaged in the card slot behind the plug head of the bowl type rubber sealing plug, and there is a handle on the upper end of the handle, on the right The housing of the chamber is provided with a sliding slot for sliding the handlebar; the cover body also has a sliding slot for sliding the handlebar, and the sliding sleeve of the cover body is inserted into the shell wall of the right chamber and Between the outer walls of the handle, and the bottom end of the sliding sleeve abuts against the inner wall of the opening edge of the bowl-shaped rubber sealing plug.

When the valve is in use, the handle of the handle is pulled, the bowl-shaped rubber sealing plug is moved upward, the valve is opened, and after the hand is released, the bowl-type rubber sealing plug automatically recovers and deforms, and the plug head is re-plugged at the water outlet, and is closed. valve. The defect is that when the valve is in the open state, it is necessary to continuously lift the handle placed on the handle, that is, the valve has a sustained force, and the use is relatively inconvenient.

发明内容Summary of the invention

The object of the present invention is to provide a self-locking liquid valve, which can complete the valve state switching in one operation, and maintain the valve state by self-locking, which is labor-saving and convenient.

To achieve the above object, the solution of the present invention is:

A self-locking liquid valve comprises a valve body, a handle, a sealing plug, a main shaft, a lower disc tooth and an upper disc tooth; a liquid passage is formed in the valve body, a vertical dam is formed on the side wall of the valve body, and a top end of the dam is formed concave The handle is mounted on the upper end of the main shaft, the sealing plug is mounted on the lower end of the main shaft, the lower disc teeth are arranged on the main shaft, and are located above the sealing plug, and the upper disc teeth are rotatably sleeved on the main shaft, and are located on the handle and the lower disc Between the teeth, at least two teeth are arranged at the upper disc teeth, and the distance between the adjacent two teeth is consistent with the width of the dam; the main shaft and the sealing plug, the lower disc teeth and the upper disc teeth mounted thereon are integrally placed on the valve In the body, the sealing plug is placed in the liquid passage, the lower disc tooth limit is located in the valve body, and the tooth peak of the lower disc tooth is offset from the tooth peak of the concave tooth of the crosspiece, and the side teeth of the upper disc tooth are located on both sides of the strip. The tooth peak of the upper disc tooth is misaligned with the tooth peak of the lower disc tooth; when the handle drives the main shaft and the upper disc tooth, the lower disc tooth and the sealing plug mounted thereon to slide upward, the tooth peak of the lower disc tooth abuts The toothed bevel of the disc tooth, the side teeth of the upper disc tooth are withdrawn from both sides of the baffle, the upper disc tooth rotates on the main shaft, and the upper disc tooth The side teeth mesh with the concave teeth of the crosspiece, the handle is hung to realize self-locking, the sealing plug is withdrawn from the liquid passage, and the liquid passage is opened; the handle drives the main shaft and the upper disc teeth, the lower disc teeth and the seal mounted thereon When the plug is slid down, the tooth peak of the lower disc tooth abuts against the tooth ramp of the upper disc tooth, the upper disc tooth rotates on the main shaft, the side teeth of the upper disc tooth are withdrawn from the concave teeth of the crosspiece, and the handle is loosened. Unlocked, the side teeth of the upper disc teeth are again located on both sides of the baffle, the sealing plug is repositioned in the liquid passage, and the liquid passage is closed.

Further, the valve body comprises a casing and a bushing, the casing forms a liquid passage, the bushing is installed in the casing, the inner side wall of the bushing forms a vertical baffle, the main shaft and the sealing plug, the lower disc tooth and the upper mounted thereon The disc teeth are integrally placed in the bushing, the sealing plug is placed in the liquid passage, the lower disc teeth are fixed in the bushing, and the tooth peaks of the lower disc teeth are offset from the tooth peaks of the concave teeth of the crosspiece, and the side of the upper disc teeth The teeth are located on both sides of the baffle, and the tooth peaks of the upper disc teeth are misaligned with the tooth peaks of the upper disc teeth.

Further, the sealing plug is composed of a plug body and a plug head; the plug body is hemispherical, the upper end of the plug body is fixed in the valve body, the middle part is fixed at the lower end of the main shaft, and the lower end is connected with the plug head.

Further, an axial chute is arranged on the baffle, and a slide rail is arranged on the lower disc tooth, and the slide rail slides up and down in the chute.

Further, one side of the concave tooth of the dam forms a slope, and when the side teeth of the upper disc slide out of the concave teeth of the dam, the side teeth slide down along the inclined surface to both sides of the dam.

Further, an adjustment spring is further included, and the adjustment spring is sleeved on the main shaft and located between the handle and the upper disc teeth.

Further, the upper cover is further included, and the upper cover is mounted on the upper end of the valve body.

After adopting the above solution, when the invention is in use, when the side teeth of the upper disc teeth slide on both sides of the crosspiece, the lower disc teeth slide downward under the elastic action of the sealing plug, and the liquid passage in the valve body is closed to close the valve.

Pulling up the handle, the lower teeth slide upward in the bushing. Due to the misalignment of the tooth peaks of the concave teeth and the tooth peaks of the lower teeth, the peaks of the lower teeth are at the tooth peaks and valleys of the upper teeth. On the slope between the lower disc teeth and the lower disc teeth continuing to slide upward in the bushing, the upper disc teeth are turned to rotate, so that the side teeth of the upper disc teeth are hung on the concave teeth of the crosspiece, and are slid into the concave teeth to engage with them. At this time, the upper disc teeth are jacked up, so that the upper disc teeth will lift the handle up, lift the hand and pull the disc teeth and the main shaft moves upwards, so that the sealing plug is lifted, the passage in the valve body is opened, and the valve is opened.

When the handle is lifted, the tooth peak of the lower disc continues to move the upper disc tooth, and at the same time, the side tooth of the upper disc slides out of the concave tooth of the crosspiece due to the distance between the adjacent teeth of the upper disc tooth. Consistent with the width of the baffle, the side teeth slide on both sides of the baffle. At this time, the tooth peak of the lower disc tooth faces the slope between the tooth peak and the valley of the upper disc tooth, and returns to the initial state of the valve closing, so repeating work.

Therefore, the present invention can open the valve once by lifting the handle upwards, and the side teeth of the upper disc teeth are hung on the concave teeth of the crosspiece to maintain the valve open state, without continuously exerting force on the valve, and at the same time, as long as Continue to lift the handle up once to close the valve, which is more labor-saving and more convenient to use.
