Abstract
The utility model provides a quick-opening ceramic chip sealed valve which comprises a valve body, a first elastic gasket ring, a fixed ceramic chip, a movable ceramic chip, a valve handle, a second elastic gasket ring, a press cover, and a handle connected to the top of the valve handle, wherein the first elastic gasket ring, the fixed ceramic chip, the movable ceramic chip, the valve handle, the second elastic gasket ring, the press cover and the handle are arranged in the valve body from bottom to top. The quick-opening ceramic chip sealed valve is characterized in that an annular groove is concavely arranged at the middle part of the inner circumferential face of the first elastic gasket ring, and the cross section of the annular groove is in the shape of a transverse U shape; an annular groove is concavely arranged at the middle part of the underside of the second elastic gasket ring, and the cross section of the annular groove is in the shape of a converse U shape. Because of the annular groove concavely arranged on the first and the second elastic gasket rings respectively, the elasticity of the gasket rings is greatly increased, the hand feeling to open and close the valve is favorable, the abrasion and the weariness damage to the gasket rings are reduced in maximum during the operation of opening and closing the valve, the service life of the gasket rings is prolonged, and the inside and outside leakage of the valve is stopped.
Description
Technical field
The utility model relates to valve, particularly a kind of good sealing effect, switching labour-saving quick open type ceramic plate sealed valve.
Background technique
For solving the deficiency that traditional ceramics sheet sealed valve Component are many, assembling difficulty big and must be multi-sealed, the Chinese utility model patent of publication number CN2632420 provides a kind of ceramic plate sealed valve, its structure is: comprise a valve body and from bottom to top be arranged at valve body interior elastic sealing gasket, definite ceramic chip, dynamic porcelain piece, valve rod, another elastic sealing gasket and valve gap, and the handle that is connected in the valve rod top, definite ceramic chip is fixed in body cavity by the position structure that is arranged at central position.But, two elastic sealing gaskets establishing in the above-mentioned ceramic plate sealed valve are common rubber gasket, the cross section of sealing gasket is the rectangular entity, so, cause open and close valve feel poor, must use and to realize complete open and close valve event, directly cause the wearing and tearing of sealing gasket than great strength, quicken the elastic fatigue of sealing gasket, influence the sealing effect of valve; So that after using a period of time, be prone to the inside and outside weeping of valve.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of good sealing effect, switching labour-saving quick open type ceramic plate sealed valve are provided, sealing gasket in the valve is carried out technological improvement, reduce wearing and tearing and the tired hurt of valve open and close process to greatest extent to seal ring, prolong the working life of seal ring, improve the sealing effect of valve.
The purpose of this utility model is achieved through the following technical solutions:
A kind of quick open type ceramic plate sealed valve, comprise a valve body and from bottom to top be arranged at first elastic sealing ring, definite ceramic chip, dynamic porcelain piece, valve rod, second elastic sealing ring, the gland of body cavity and the handle that is connected in the valve rod top, it is characterized in that: the inner peripheral surface middle part of described first elastic sealing ring is concaved with annular groove, and its cross section is
Type; The middle part, bottom surface of described second elastic sealing ring is concaved with annular groove, and its cross section is the ∩ type.
Be provided with wear-resisting non-rigid pad between the gland on the described second elastic sealing ring top and the pressing surface of valve rod, this non-rigid pad is fitted on second elastic sealing ring.
For preventing the dislocation of first elastic sealing ring, in the annular groove of first elastic sealing ring, be arranged with a limited ring.
The both sides correspondence of described definite ceramic chip is provided with integrated protuberance, and correspondence is provided with groove on the body cavity wall, and definite ceramic chip is fixed in body cavity by protuberance, groove.
Above-mentioned quick open type ceramic plate sealed valve is the rectangular sealing gasket of entity to existing cross section and improves, and is concaved with annular groove at the inner peripheral surface middle part of first elastic sealing ring, and its cross section is
Type; Middle part, bottom surface at second elastic sealing ring is concaved with annular groove, and its cross section is the ∩ type.Compare with existing sealing gasket,, improved the elasticity of seal ring greatly, open and close valve good hand touch owing in seal ring, offer annular groove; Enter the annular groove notch that water flow pressure in the valve acts on first, second elastic sealing ring, make the annular groove notch of first, second elastic sealing ring stressed and outer, further improve the sealing effect of valve.This quick open type ceramic plate sealed valve sealing good stability, laborsaving, the good hand touch of open and close operation, reduce wearing and tearing and the tired hurt of valve open and close operation process to greatest extent, slow down the working life that prolongs seal ring, stop valve and inside and outside weeping occurs seal ring.
