Embodiment
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, the present embodiment comprises main body 1, and main body 1 lower end surface is provided with outlet 2, and on the right side of main body 1, other end is provided with import 13; Be fixedly connected with above main body 1 and be provided with body cover 4, main body 1 coordinates with body cover 4 and is provided with body cover seal ring 3; The cooperation of body cover 4 intermediate space is provided with small piston rod 7, and on small piston rod 7, interference fit is provided with locating stud 17, and body cover 4 is provided with the gradient groove with locating stud 17 Structure deformation, and small piston rod 7 top is threaded and is provided with rotating disk 6; Small piston rod 7 coordinates with body cover 4 and is provided with small piston rod seal ring 8, and be provided with spring 9 between small piston rod 7 and small piston rod seal ring 8 bottom surface, small piston rod 7 is provided with the spring baffle ring contacted with spring 9; Body cover 4 internal void coordinates and is provided with large piston 11, is provided with pilot hole in the middle of large piston 11, and small piston rod 7 is provided with small piston seal ring 10 with coordinating between pilot hole; Be provided with sealed cylindrical 16 in the middle part of main body 1, large piston 11 is provided with large piston packing 12 with coordinating between sealed cylindrical 16.
Patent of the present invention is set to further, be fixedly connected with between main body 1 with body cover 4 and be provided with attachment screw 5, body cover 4 is provided with the body cover seal groove coordinated with body cover seal ring 3, body cover 4 is provided with the body cover inner chamber 14 with large piston 11 Spielpassung, and large piston 11 is 2-4mm with body cover inner chamber 14 gap; Large piston 11 end face is provided with damping groove, and damping groove is communicated with pilot hole, and large piston left end is coniform, and large piston 11 is provided with the large piston seal ring recess coordinated with large piston packing 12.
Patent of the present invention is set to further, and small piston rod 7 end face is provided with tapped hole, and being threaded between small piston rod 7 with rotating disk 6 is provided with rotating disk set screw 18, and small piston rod 7 is provided with the pin-and-hole with locating stud 17 interference fit.
Patent of the present invention is set to further, and sealed cylindrical 16 and main body 1 are integrated, and sealed cylindrical 16 inside is provided with closed cavity 15, and closed cavity 15 communicates with outlet 2.
During actual use, first the spring baffle ring on small piston rod 7 moves downward under the active force of spring 9, thus the small piston seal ring 10 on small piston rod 7 is pressed on the pilot hole of large piston 11, and then order about large piston 11 and move downward in body cover inner chamber 14 inside, large piston packing 12 on final large piston 11 is pressed on sealed cylindrical 16, thus realizes closed condition, when the import 13 of tap water on the right side of main body 1 flows into, water enters body cover inner chamber 14 by the gap between large piston 11 and body cover inner chamber 14, due under the active force of hydraulic power and spring 9, pilot hole is closed, large piston 11 is also in closed state, when rotary turnplate 6 gently, rotating disk 6 drives small piston rod 7 to rotate, thus locating stud 17 is followed and is moved obliquely along the gradient groove in body cover 4, thus small piston rod 7 is lifted open, small piston seal ring 8 is separated with pilot hole, liquid flows into closed cavity 15 from pilot hole rapidly, thus flow to outlet 2, because liquid flows out rapidly, thus cause large piston 11 upper body cover cavity 14 pressure to decline rapidly, and then large piston about 11 forms pressure difference, under the effect of pressure reduction, large piston 11 is lifted rapidly, thus realize water tap opening state, when liquid constantly enters body cover inner chamber 14 by the gap between large piston 11 and body cover inner chamber 14, body cover inner chamber 14 pressure is slowly made up and spring 9 is produced reaction force owing to compressing, and then order about small piston rod 7 and move downward, because locating stud 17 produces certain time expand with the gradient groove generation sliding friction in body cover 4, and then be beneficial to water tap continuation flowing water, small piston seal ring 10 after a period of time on small piston rod 7 is pressed on the pilot hole of large piston 11, order about large piston 11 again to move downward in body cover inner chamber 14 inside, large piston packing 12 on final large piston 11 is pressed on sealed cylindrical 16, thus realize water tap closedown.
Utilize the technological scheme described in patent of the present invention, or those skilled in the art being under the inspiration of art solutions of the present invention, designs similar technological scheme, and reaching above-mentioned technique effect, is all the protection domains falling into patent of the present invention.
