Description

Technical Field

[0001] The utility model relates to the technical field of ceramic valve cores, in particular to a multifunctional combined ceramic valve core. Background Art

[0002] The ceramic material has high tensile strength, is not easy to deform, is resistant to high and low temperatures, is resistant to wear and corrosion, and has excellent sealing performance. At the same time, the ceramic valve core is resistant to aging, wear and maintenance, ensuring the stability of operation.

[0003] A combined ceramic valve core is provided in the related art, and the combined ceramic valve core includes a valve body, an upper valve core and a lower valve core. Flow holes are provided on the surfaces of the upper valve core and the lower valve core, and the upper valve core is sealingly rotatably mounted on the lower valve core. An annular strip is provided on the upper end of the upper valve core, and an annular groove is provided on the upper end of the valve body at a position corresponding to the position where the annular strip of the upper valve core is provided. The annular strip provided on the upper end of the upper valve core is movably installed in the annular groove provided on the upper end of the valve body;

[0004] When using the combined ceramic valve core, for example, when the flow rate of the combined ceramic valve core needs to be adjusted, a force is applied to the surface of the upper valve core to push the upper valve core to rotate around the lower valve core. During the process of the upper valve core rotating around the lower valve core, the annular strip provided at the upper end of the upper valve core rotates in the annular groove opened at the upper end of the valve body. In this way, although it can ensure that after the force is applied to the upper valve core, the annular strip provided at the upper end of the upper valve core rotates in the annular groove opened at the upper end of the valve body; however, when the operator stops pushing the upper valve core to rotate, the impact force generated by the liquid flow rate will push the upper valve core, thereby automatically changing the flow rate of the entire combined ceramic valve core;

[0005] In view of the problems in the above background technology, the utility model aims to provide a multifunctional combined ceramic valve core. Utility Model Content

[0006] The purpose of the utility model is to provide a multifunctional combined ceramic valve core to solve the problems raised in the above background technology.

The lower valve core is fixed at the lower end of the valve body, and the upper valve core is slidably installed between the upper end of the lower valve core and the lower end of the valve body in an annular shape. The surface of the lower valve core is provided with a first large flow hole, a first medium flow hole and a first small flow hole, respectively, and the surface of the upper valve core is provided with a second medium flow hole and a second small flow hole, and a push plate is also installed on the upper valve core;

[0010] In addition, the upper end of the upper valve core and the lower end of the valve body can not only ensure the sealing of the upper valve core installed inside the valve body, but also allow the upper valve core to rotate around the upper end of the lower valve core, and the clamping component for adjusting the discharge flow rate of the entire multifunctional combined ceramic valve core is movably installed.

[0011] As a further solution of the utility model: the lower valve core is T-shaped, and a positioning hole is provided on one side of the lower end of the valve body; at the same time, the outer edge of the lower valve core is raised, and a jacket is provided inward at the lower end of the upper valve core, and the jacket provided at the lower end of the upper valve core is annularly slidably installed on the lower valve core.

[0012] As a further solution of the utility model: the clamping assembly includes a bracket, a movable cylinder and a limit frame, the limit frame is installed and fixed on the upper valve core, the movable cylinder passes through the middle of the limit frame, the lower end of the movable cylinder is equipped with a compression spring, and the upper end of the movable cylinder is connected to the lower end of the bracket; at the same time, a rolling ball is placed inside the bracket, an arc groove is opened at the upper end of the valve body, and the upper end of the rolling ball placed inside the bracket contacts the inner wall of the arc groove opened at the upper end of the valve body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Compared with the existing combined ceramic valve core, the multifunctional combined ceramic valve core changes the original way that the upper valve core contacts the valve body through the annular groove and the annular strip, and innovatively designs that the upper valve core and the valve body are in contact through a clamping assembly; the clamping assembly includes a bracket, a movable cylinder and a limit frame, and a compression spring is sleeved on the lower end of the movable cylinder; a rolling ball is placed inside the bracket, and an arc groove is opened on the upper end of the valve body, and the upper end of the rolling ball placed inside the bracket contacts the inner wall of the arc groove opened on the upper end of the valve body;

[0015] The clamping assembly provided can ensure that the operator can easily push the upper valve core to rotate around the lower valve core by applying force at the position of the upper valve core, and after the force on the upper valve core is stopped, the compression spring provided can deform to produce an elastic variable to push the movable cylinder to lift, so as to make the upper end of the rolling ball squeeze the inner wall of the arc groove, thereby preventing the liquid with too large flow path from pushing the valve core to operate after the operator stops applying force to the push plate, thereby changing the flow rate of the adjusted multi-functional ceramic valve core.
