Description

high-strength composite valve core

Technical Field

The utility model relates to a hot-water heating bathroom technical field, concretely relates to kinds of high strength composite valve core.

Background

The valve core is used as a core component of the water faucet and plays a role in closing/opening/regulating flow, the valve core is a sealed valve core with a patent network publication number of CN208670119U and a patent name of , and comprises a valve core shell with a water inlet and a water outlet, a ceramic moving plate and a ceramic static plate which are arranged in the valve core shell, a sealed inner container which drives the ceramic moving plate to rotate, and a valve rod which drives the sealed inner container to rotate, wherein a sealing gasket is arranged at the bottom of the ceramic static plate, the valve rod is detachably connected with the sealed inner container, an annular table surface and an annular table surface II are sequentially arranged on the inner wall of the valve core shell from top to bottom, an annular positioning table surface which is matched with an annular table surface and used for fixing a sealing ring and an annular limiting table surface which is matched with the annular table surface II and used for fixing a lubricating gasket are sequentially arranged on the outer side of the sealed inner container from top to bottom, at least sealing rings II which are sealed with the inner wall of the valve core:

1. because the lubricating gasket is arranged between the top end of the annular limiting table surface and the second annular table surface, when the valve core is assembled, the sealing liner can be inverted to a certain end, the lubricating gasket can fall off, and the assembly is troublesome.

2. When the valve core works, the water outlet or the water closing of the faucet needs to be controlled, the valve rod drives the sealing liner to rotate, the lubricating gasket is limited between the valve body and the sealing liner, the lubricating gasket is abraded, and therefore materials such as dust and the like after the lubricating gasket is abraded can be mixed with a water source to cause water pollution.
