Detailed Description
The technical solution of the present invention is further illustrated by the accompanying drawings and examples.
Example 1
A quick-opening valve core comprises a valve body 2, wherein a convex ring 6 is arranged in an inner cavity of the valve body 2, a positioning groove is reserved on the convex ring 6, a positioning disc 8 is assembled on the convex ring 6, a positioning boss 101 on the lower end face of the positioning disc is matched with the positioning groove reserved on the convex ring 6, a sealing gasket a5 is assembled in a sealing groove 105 on a ceramic stator 4, the assembled ceramic stator 5 is assembled with the positioning disc 8, a positioning pin 102 on the upper end face of the positioning disc is matched with a positioning hole 113 on the lower end face of the ceramic stator 5, a sealing gasket a5 is tightly attached to the upper end face of the convex ring 6, the lower end face of the ceramic rotor 3 is tightly attached to the upper end face of the ceramic stator 5, a valve rod 10 is inserted from the upper end of the valve body 2, a lug a111 on the valve rod is matched with a positioning groove 106 on the ceramic rotor 3, a lug b112 on the valve rod 10 is matched with a limiting groove 103 on the ceramic stator, the sealing gasket b11 is assembled on the shaft shoulder of the valve rod 10, the valve cover 1 is assembled on the valve body 1 by screw threads, and the edge of the hole on the side of the valve cover 1 facing the cavity of the valve body is tightly attached with the sealing gasket b 11.
The working principle is as follows: after the assembly is finished, the convex claw a111 on the valve rod 10 is matched with the positioning groove 106 on the ceramic rotor 3, the positions of the two are relatively fixed, the convex claw b112 is positioned at one end of the limiting groove 103 on the ceramic stator 5, and at the moment, the hole a104 on the ceramic stator 5 and the hole b107 on the ceramic rotor 3 are completely misaligned, because the ceramic rotor 3 of the ceramic stator 5 is tightly attached and the surfaces of the two are smooth enough, water flow can not pass through the gap at the moment, and then the closed state is formed; when the valve rod 10 is rotated, the convex claw a111 on the valve rod 10 drives the ceramic rotor 3 to rotate, when a certain angle is reached, the hole a104 on the ceramic stator 5 and the hole b107 on the ceramic rotor 3 start to coincide, water flows in from the gap of the coinciding part from the water inlet 7 and flows out from the water outlet 9, at the moment, an 'open' state is formed, when the valve rod 10 continues to rotate for a certain angle, the convex claw b112 on the valve rod 10 reaches the other end of the limiting groove on the ceramic stator 5, at the moment, the valve rod cannot continue to rotate along the original direction, the hole a104 on the ceramic stator 5 and the hole b107 on the ceramic rotor 3 completely coincide, and at the moment, the 'maximum' state is formed.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
