Rotary valve core structure

Abstract

The invention discloses a rotary valve core structure which is successively composed of an upper valve core, an inner valve core sleeved in the upper valve core and a lower valve core sleeved and mounted to the inner valve core partially from top to bottom. An upper clamping strip mounted matched with a hand wheel or a handle to drive the upper valve core to rotate to be protruded is arranged on the outer side of the upper valve core, the upper valve core along the direction of a center axle is provided with an upper valve core cavity penetrating the whole upper valve core, and a slot is sunken in the upper valve core cavity; the inner valve core is of a columnar structure and a middle clamping strip mounted to the slot in a fit manner is formed on the lower part, the inner valve core is provided with an inner valve core cavity closed at the single side from the upward direction of the bottom, and the inner valve core penetrates the upper valve core cavity and protrudes out of the topof the upper valve core. The lower valve core comprises an upper valve rod inserted into the inner valve core cavity, a lower valve rod connected and mounted to the upper valve rod, a valve rod coversleeved to the periphery of the upper valve rod and mounted and joined to the middle clamping strip and a seal ring sleeved to the connecting position of the upper valve rod and the lower valve rod. The rotary valve core structure is small in occupied space, can move all around, and is good in water control effect, comfortable to use and low in noise.

Description

technical field [0001] The invention relates to the structural field of valve cores, in particular to a rotary valve core structure. Background technique [0002] At present, the valve core on the market is installed in the faucet to control the water flow switch and the flow rate. The valve cores used for faucets include hemispherical valves, gate valves, etc. These two types of valve cores are relatively traditional and the most popular. The half-ball valve is switched through the spherical surface on one side of the valve core and the through hole on the other side to control fluid flow and closed and closed, and the gate valve controls the fluid flow and closing through up and down displacement. Whether it is a hemispherical valve or a gate valve, the valve core will age over time, that is, when the knob of the control core handle is rotated by hand, the hand will feel very hard, and the knob is exposed outside the faucet, occupying a lot of space, in some special In t...

AI Technical Summary

Problems solved by technology

Whether it is a hemispherical valve or a gate valve, the spool will age over time, that is, when you turn the knob of the control core handle by hand, the hand will feel very strenuous, and the knob is exposed outside the faucet, taking up a lot of space. In some special In some cases, a person may fall and hit the knob to cause injury

Moreover, the protruding rod of the current spool moves left and right inside the spool, and the water control effect is poor. When the water pressure is low, the water flow is small
