[0015] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0016] See also Figure 3-5 and Figure 7 ,

[0017] A water pipe valve comprises a shell 101, a water outlet pipe 102 is welded to the lower end of the shell 101, a valve plate 103 is rotatably connected to the shell 101 through a bearing, a rotating rod of the valve plate 103 extends to the outside of the shell 101, and a handle 104 is fixedly connected to the upper end of the valve plate 103 by bolts, a limiting frame 201 is welded to the upper end of the outer shell 101, a sliding rod 203 is slidably connected to the limiting frame 201, a push claw 206 is welded to one end of the sliding rod 203, and an elastic member 204 is welded to the other end of the sliding rod 203, the lower end inclined portion of the elastic member 204 can undergo elastic deformation, a clamping plate 202 is welded to the limiting frame 201, and the lower end inclined portion of the elastic member 204 contacts the clamping plate 202, a first spring 205 is sleeved on the sliding rod 203, and the first spring 205 is located between the limiting frame 201 and the push claw 206, and a trigger mechanism is connected to the shell 101.

[0018] When using the water pipe valve, the user drives the valve plate 103 to rotate by turning the handle 104, thereby realizing the opening and closing function of the valve plate 103. When the handle 104 is in a state perpendicular to the shell 101, the valve plate 103 is in an open state, and water can flow into the outlet pipe 102 through the shell 101 and finally be discharged through the outlet pipe 102, thereby realizing the water circulation function. When the handle 104 is in a state parallel to the shell 101, the valve plate 103 is in a closed state, and water cannot flow into the outlet pipe 102 from the shell 101, thereby realizing the drainage stop function.

[0019] After a long period of use, a water pipe valve may become clogged due to the accumulation of impurities, thereby affecting the discharge of water, increasing the pressure inside the water pipe valve, and increasing the risk of valve damage. As a result, the water pipe valve needs to be disassembled and cleaned regularly. The first spring 205 of the water pipe valve of the present application is in a state of force compression. When a blockage occurs, the trigger mechanism can push the lower inclined part of the elastic member 204 upward, so that the elastic member 204 is separated from the clamping plate 202. At this time, the slide rod 203 slides to the right under the elastic action of the first spring 205, and at the same time drives the push claw 206 to push the handle 104, so that the handle 104 rotates a quarter of a circle, thereby driving the valve plate 103 to close.

[0020] Through the above structure, the water pipe valve can automatically close the valve plate 103 when the pressure increases due to internal blockage, thereby stopping the flow of water and avoiding damage to the internal structure of the water pipe valve. At the same time, the user can be reminded by observing the positions of the push claw 206 and the handle 104, so as to clean the inside of the water pipe valve in time.

[0021] When the inside of the water pipe valve is cleaned, the slide bar 203 is pulled leftward so that the elastic member 204 is clamped on the clamping plate 202 again.

[0022] See also Figure 6 ,

[0023] The trigger mechanism includes a pressure tube 301, which is welded to the upper end of the outer shell 101. A sliding plug 302 is slidably connected inside the pressure tube 301, and a push rod 303 is welded to the upper end of the sliding plug 302. A second spring 304 is arranged between the sliding plug 302 and the inner wall of the pressure tube 301, and the push rod 303 is located below the elastic member 204.

[0024] When the pressure in the water pipe valve increases due to blockage, the sliding plug 302 is pushed upward under the action of pressure, and the sliding plug 302 drives the push rod 303 to slide upward and extend. At the same time, the second spring 304 is compressed by the force, and the push rod 303 contacts the inclined part of the lower end of the elastic member 204 when extending upward, so that the elastic member 204 can be separated from the clamping plate 202, thereby realizing the function of closing the valve plate 103.

[0025] See also Figure 3-4 ,

[0026] A filter plate 402 is slidably connected in the housing 101 , and a plurality of strip-shaped filter slots are formed on the filter plate 402 .

[0027] The filter plate 402 has the function of filtering water. When water passes through the filter plate 402, the filter plate 402 can isolate impurities in the water, and the water continues to flow through a plurality of strip filter slots and is discharged.

[0028] See also Figure 4 ,

[0029] The filter plate 402 is located on the right side of the water outlet pipe 102. The water is first filtered by the filter plate 402 and then discharged through the water outlet pipe 102, thereby achieving a complete filtering function.

[0030] See also Figure 4 ,

[0031] The filter plate 402 is located on the left side of the pressure tube 301. When impurities accumulate on the filter plate 402 and cause blockage, the pressure in the space on the right side of the filter plate 402 increases, thereby pushing the sliding plug 302 in the pressure tube 301 to slide upward.

[0032] See also Figure 6 ,

[0033] The filter plate 402 is fixedly connected with a limit rod 401 by means of bolts. The limit rod 401 is slidably connected to the inner wall of the housing 101 and extends to the outside of the housing 101 .

[0034] The limit rod 401 serves to limit the filter plate 402, and can ensure that the filter plate 402 slides horizontally. When the filter plate 402 is blocked and the internal pressure of the shell 101 increases, the user controls the limit rod 401 to slide, and the limit rod 401 drives the filter plate 402 to slide to the left, so that the filter plate 402 is located on the left side of the water outlet pipe 102. At this time, the filter plate 402 no longer plays a filtering role, and water can be discharged smoothly through the water outlet pipe 102, thereby achieving the effect of pressure relief.

[0035] See also Figure 3-4 ,

[0036] A plurality of strip-shaped inserts 406 are welded and fixedly connected to the inner wall of the housing 101 , and the plurality of strip-shaped inserts 406 correspond to the positions of the plurality of strip-shaped filter slots respectively.

[0037] When the filter plate 402 moves to the left, the multiple strip inserts 406 can be respectively inserted into the multiple strip filter slots, so that the multiple strip filter slots can be dredged and the blocked impurities can be removed. At the same time, the valve plate 103 is reopened to allow the water flow to flush the dredged filter plate 402 and discharge the removed impurities, thereby realizing the function of internal cleaning without disassembly.

[0038] After the filter plate 402 is cleaned, the filter plate 402 is slid to the left to reset the filter plate 402. At this time, the filter plate 402 can continue to play a filtering role.

[0039] See also Figure 2 ,

[0040] A screw rod 404 is rotatably connected to the outer wall of the housing 101 via a bearing, a movable plate 403 is threadedly connected to the screw rod 404, and the movable plate 403 is fixedly connected to the end of the limiting rod 401 via bolts.

[0041] The user can drive the movable plate 403 to move by rotating the screw rod 404, and the movable plate 403 drives the limit rod 401 to slide, and the limit rod 401 drives the filter plate 402 to slide. By rotating the screw rod 404 to control the filter plate 402, the filter plate 402 can be prevented from being displaced due to accidental touching of the limit rod 401.

[0042] See also Figure 2 ,

[0043] The end of the screw rod 404 is fixedly connected to a handle 405 via a bolt.

[0044] The user can control the rotation of the screw rod 404 by manually operating the handle 405 .

[0045] See also Figure 7 ,

[0046] The elastic member 204 is made of spring steel, which has good elasticity and recovery ability, thereby extending the service life of the elastic member 204.
