Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a simple valve capable of adjusting flow rate by pressing. Background Art

[0002] Valves are common mechanical structures that can be found in faucets, gas stoves, and other locations. Taking the valve in a faucet application scenario as an example, the valve needs to withstand frequent reciprocating rotation during its service life to achieve water flow regulation. The traditional valve is connected to the faucet main structure through a threaded structure. Its frequent reciprocating rotation will continue to cause its own wear and loosening, and quickly shorten the service life of the valve. Based on this situation, how to achieve flow regulation at the faucet position while avoiding frequent rotation of the valve and the resulting shortening of the valve's service life is becoming an increasingly urgent problem that relevant technical personnel need to solve.

[0007] Furthermore, a transverse groove is horizontally provided at the middle position of the outer side of the slider, and an annular spring is horizontally provided at the outer periphery of the slider, and the annular spring is fitted with the surface of the transverse groove.

[0008] Furthermore, inner holes are symmetrically arranged on both sides of the column, a limit rod is slidably arranged on the inner side of the inner hole, a horizontal spring is arranged inside the inner hole, two ends of the horizontal spring are respectively fixedly connected to the column and the limit rod, upper clamping grooves are symmetrically arranged on both sides of the valve sleeve, a lower clamping groove is arranged directly below the upper clamping groove, the upper clamping groove and the lower clamping groove correspond to the positions of the limit rod, the end of the limit rod away from the horizontal spring is an outward convex spherical surface, and the surfaces of the upper clamping groove and the lower clamping groove are both inward concave spherical surfaces.

[0014] 1. In the default state, the end of the limit rod is connected to the upper slot. The user only needs to press the button until the end of the limit rod is connected to the lower slot to complete the water flow adjustment. Compared with the traditional valve and faucet main structure connected by a threaded structure, it effectively avoids frequent rotation of the valve and the resulting shortening of the valve service life;

[0015] 2.

On this basis, the design of the upper hole, the lower hole and the middle hole corresponding to each other effectively ensures the stability of the flow rate during the adjustment process and after the final adjustment is completed;

[0016] 3. The horizontal spring provides a good structural basis for the stable connection between the limit rod and the upper and lower slots. The center spring provides a good structural basis for the accumulation of kinetic energy before the column moves up (that is, the accumulation of its own elastic potential energy). The user only needs to press the button again and release it after the water is used. The column can be reset by compressing the center spring. The annular spring provides a good structural basis for the automatic reset of the slider, thereby effectively ensuring the convenience of the flow regulation process and the stability of the regulation effect.

The middle hole 11 is completely staggered with the upper hole 12 and the lower hole 10. No water flows out of the lower hole 10. When the user wants to use water, he presses the button 1 downward. During this process, the column 2 moves vertically downward, the upper inclined portion 17 and the lower inclined portion 23 are attached and push the slider 6 to move horizontally outward along the slide groove 8 until the middle hole 11 is completely connected with the upper hole 12 and the lower hole 10. At the same time, the end of the limit rod 3 moves out from the upper clamping groove 13, passes through the transition portion 14, and moves in and Snapped into the lower slot 15, the horizontal spring 18 keeps the limit rod 3 and the lower slot 15 snapped stably. At this time, the lower hole 10 is in a stable position to discharge water, and the user can use water normally. After using water, press the button 1 until it reaches the lowest position of its stroke. At this time, the center spring 9 is compressed to the limit state, and the elastic potential energy accumulates to the maximum value. Release the button 1, and the center spring 9 quickly resets, while pushing the column 2 to move vertically upward until it resets. The limit rod 3 moves vertically upward with the column 2 and snaps into the upper slot 13 again, and the annular spring 22 contracts accordingly, so that the slider 6 resets along the slide groove 8, and the middle hole 11 is completely staggered with the upper hole 12 and the lower hole 10 again. The flow rate at the position of the lower hole 10 is reset to zero, and a complete use process is completed.
