A return mechanism 8 is also arranged in the valve core shell 3, and the return mechanism 8 can act on the pressure rod 5 and the sealing core 6 and enables the pressure rod 5 and the sealing core 6 to have the tendency of moving upwards. The push type valve core further comprises an adjusting piece 9 connected to the top of the sliding claw sleeve 4, the adjusting piece 9 can move relative to the sliding claw sleeve 4 along the axial direction of the pressing rod 5 and is positioned after moving, and the upper end of the pressing rod 5 abuts against the lower end of the adjusting piece 9.

Specifically, the top of the sliding claw sleeve 4 is open, a cylindrical adjusting seat 10 penetrates through the opening, a protruding annular convex edge is arranged on the outer side of the lower end of the adjusting seat 10, the convex edge abuts against the lower side surface of the top of the sliding claw sleeve 4 under the axial acting force of the pressure lever 5 through the adjusting seat 10, and the adjusting seat 10 can rotate circumferentially relative to the sliding claw sleeve 4. The adjusting part 9 comprises an adjusting screw 11 screwed in the adjusting seat 10 and a vertically arranged operating rod 14. The lower end face of the adjusting seat 10 is provided with a concave circular positioning groove, the outer side of the lower end of the adjusting screw 11 is provided with a convex circular blocking edge 13, and when the adjusting screw 11 moves upwards relative to the adjusting seat 10, the blocking edge 13 on the adjusting screw 11 can be retracted into the positioning groove and abut against the lower end of the fixing cap. The lower end face of the adjusting screw 11 is also provided with a concave positioning hole, and the upper end of the pressure rod 5 is propped against the bottom of the positioning hole. The outer side of the upper part of the adjusting screw 11 extending out of the adjusting seat 10 is provided with a convex annular limiting part 12, and the limiting part 12 can be abutted against the upper end of the adjusting seat 10 when the adjusting screw 11 moves downwards relative to the adjusting seat 10. The lower end of the operating rod 14 is sleeved on the outer side of the adjusting screw 11 and fixed with the adjusting screw 11, and the outer side surface of the operating rod 14 is provided with a convex operating part. In this embodiment, the limiting portion 12 is a retainer ring axially fixed on the outer side of the adjusting screw 11 and a reinforcing nut fixedly connected to the adjusting screw 11; the operating portions on the outer side of the operating lever 14 are spaced apart from each other, so that an uneven shape is formed on the outer side surface of the operating lever 14 to facilitate connection of the operating mechanism.

The telescopic mechanism comprises a telescopic push rod 19 sleeved on the sliding claw sleeve 4, a cylindrical pressing barrel 20 is further in threaded connection with the outer side of the telescopic push rod 19, the pressing barrel 20 is also sleeved on the outer side of the operating rod 14, the upper end of the pressing barrel 20 is lower than the upper end of the operating rod 14, and namely the upper end of the operating rod 14 extends out of the pressing barrel 20. The structure, connection relationship and operation principle of the telescopic mechanism and the return mechanism 8 are the same as those of the above-mentioned prior application of the applicant, and are not described herein again. The upper end of the adjusting seat 10 penetrates through the top of the telescopic push rod 19, the adjusting seat 10 and the telescopic push rod 19 are circumferentially fixed through a polygonal spline, and the adjusting seat 10 can axially move relative to the telescopic push rod 19.

The inside of the valve core shell 3 is also provided with a sheet-shaped sealing element 15, the edge of the sealing element 15 is made of rubber materials and is tightly pressed on the inner wall of the valve core shell 3 to form sealing communication, the sealing element 15 separates the water inlet 1 and the water outlet 2 at the lower side, the upper side of the sealing element 15 forms a water passing cavity 16, and the lower end of the sealing core 6 extends into the water passing cavity 16. The sealing element 15 can move downwards under the action of water pressure and the sealing core 6 to block the water outlet 2 or hover to form water passing channels with different areas, a water inlet 17 capable of communicating the water inlet 1 with the water passing cavity 16 and a pressure relief hole 18 capable of communicating the water outlet 2 with the water passing cavity 16 are formed in the sealing element 15 in a penetrating mode, the diameter of the pressure relief hole 18 is larger than that of the water inlet 17, and the sealing core 6 can move downwards to abut against the sealing element 15 and block the pressure relief hole 18.

This novel push type case is when normal use, and the accessible is direct to be pressed and is pressed a section of thick bamboo 20 for slide jaw cover 4 carries out the position conversion between high-order and low level under telescopic machanism's effect, and then drives sealed core 6 through depression bar 5 and remove in order to switch on and block water channel, realizes opening and closing of case.

When the valve core is in an opening state, the sliding claw sleeve 4 is located at a high position, the sealing core 6 and the pressure rod 5 both move upwards to the upper end of the pressure rod 5 and abut against the lower end of the adjusting part 9 under the action of the return mechanism 8, at the moment, the sealing core 6 is far away from the sealing part 15, the pressure relief hole 18 on the sealing part 15 is opened, and water in the water passing cavity 16 flows out to the water outlet 2. Because of the aperture of pressure release hole 18 is greater than the aperture of inlet opening 17, the velocity of water outlet of crossing cavity 16 department is greater than the velocity of water inlet, water pressure reduces gradually, under the water impact of water inlet 1 department, sealing member 15 moves up to be close and open delivery port 2 with sealed core 6 lower extreme, in the in-process that sealing member 15 is close sealed core 6 gradually, the velocity of water outlet of crossing cavity 16 department reduces gradually, the water pressure in crossing cavity 16 rises gradually, when the clearance between sealing member 15 and sealed core 6 reaches certain numerical value, the water pressure of sealing member 15 both sides is balanced gradually, sealing member 15 no longer removes, be in the state of hovering, rivers are from water inlet 1 through the clearance between sealing member 15 and the delivery port 2 stably flow out.

If the flow at the valve core needs to be adjusted, the operating rod 14 is rotated to drive the adjusting screw rod 11 to move downwards relative to the adjusting seat 10, the pressure rod 5, the sealing spring 7 and the sealing core 6 are ejected downwards, and because the water pressure at two sides of the sealing element 15 is balanced, the sealing element 15 can also move downwards in the downward movement process of the sealing core 6, so that the distance between the sealing element 15 and the water outlet 2 is reduced, the flow of water flow is reduced, and the flow adjustment is realized. This flow regulation process can be performed with the valve spool in an open or closed state.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
