Abstract

The utility model relates to a valve spool leading water to enter from the bottom and having a closing function. A casing (2) is arranged outside a driving lever (1); a counter bore (3) provided with a spring (4) and a positioning ball (3) is arranged on the driving lever (1); the driving lever (1), the spring (4) and the positioning ball (3) are assembled in the casing (2); and a ceramic movable plate (5), a ceramic fixed plate (6), an internal sealing ring (7), a base (8) and an external sealing ring (9) are sequentially assembled in the lower portion of the casing (2) provided with the driving lever (1). The valve spool adopts the ceramic movable plate and the ceramic fixed plate as main switching components, abrasion resistance is improved, the service life of the valve spool is prolonged, reliability of the valve spool is enhanced, and the valve spool is more convenient in use. The valve spool can be widely used on various universal water faucets of sanitary ware, and has the functions of opening or closing cold water, hot water and mixed water, switching over the cold water, the hot water and the mixed water in a water supply state, and controlling water flow rate.

Description

The bottom water inlet has the valve spool of closing function

Technical field

The utility model relates to a kind of valve spool, and the water inlet of particularly a kind of bottom has the valve spool of closing function.

Background technique

Be installed in the commutation plastics ceramic valve core of the various universal water taps of sanitary ware, its purposes plays opening between cold water, hot water, the mixing water, close, and can switch mutually under the water supply state and the effect of controlled water flow amount.In the prior art, the water intake of commutation plastics ceramic valve core is located at the side of spool shell, Jin Shui plastic valve core housing from the side, can wear out, be out of shape by the regular hour, there is not closing function, and do not have close function, in many industrial occasions, can't use, directly influence spool working life.How changing the defective of prior art, is technical problem demanding prompt solution.

The model utility content

In order to solve the technological deficiency that prior art exists, it is from bottom ceramic plate water inlet and outlet that the purpose of this utility model is to provide a kind of spool, and what cross water is stupalith, forever indeformable, has stopped water and has contacted with plastic materials, has improved spool working life.The flow path of the ceramic valve core of flowing through is shortened, reduced noise simultaneously, and increased closing function, enlarged using scope.By checking, fundamentally solve the problem that leaking appears in the water intake material deformation.Its volume is little, and wear-resisting property is good, and long service life is used simple to operately, and cost is low.

To achieve these goals, the technical solution of the utility model is: the water inlet of a kind of bottom has the valve spool of closing function, comprise housing, spring, inner seal ring, the pottery moving plate, ceramic stator, it is characterized in that: housing is in the driving lever outside, driving lever is provided with the counterbore of assembling spring and place kick, assembling spring and place kick in the counterbore, driving lever, spring and place kick are assemblied in the housing, assembling ceramic moving plate successively in the housing of bottom of assembling driving lever, ceramic stator, inner seal ring, base and exterior seal ring, wherein, an end face of inner seal ring cooperates with an end face of ceramic stator, another end face of inner seal ring cooperates with an end face of base, and an end face of exterior seal ring cooperates with an end face of base.

Preferably, described base is provided with the water inlet, and wherein, the upper-end surface of base is provided with the groove of assembling inner seal ring, and the lower end surface of base is provided with the groove of assembling exterior seal ring.

Preferably, the groove fit of the assembling inner seal ring of the upper-end surface base of described inner seal ring and base, inner seal ring is entrenched in the groove.

Preferably, the groove fit of the assembling exterior seal ring of the lower end surface base of described exterior seal ring and base, exterior seal ring is entrenched in the groove.

The beneficial effects of the utility model are: because after adopting such scheme, reach the standard-required of country through life test, fundamentally solve because of material aging, the water leakage phenomenon that distortion causes has improved spool working life.And increased closing function, enlarged using scope.The utility model adopts ceramic moving plate, ceramic stator as main switch part, improves wear resistance, improves the working life and the reliability of product, uses more convenient.The utility model can extensively be used on the various universal water taps of sanitary ware, and its purposes plays opening between cold water, hot water, the mixing water, close, and can switch mutually under the water supply state and the effect of controlled water flow amount.
