Abstract

The utility model relates to a ceramic full sealing valve, which is composed of a valve body, a valve rod and a ceramic sealing valve sheet. A flowing path and a stopping gate are composed of a static valve sheet and a movable valve sheet. When used, the valve body and the valve rod thoroughly do not have fluid medium. The utility model is a new structure with simple and reliable sealing performance.

Description

The pottery full-sealing valve

The utility model belongs to valve field, refers in particular to a kind of ceramic hermetically sealed shutoff valve of pipe valve type.

Present commercially available traditional shutoff valve, mostly its seal element is to adopt elastomeric polymeric material, and reach opening of valve and end with the lifting of helical screw, because macromolecular material is easily aging and wearing and tearing, valve usually produces water clock even loses by effect, the spiral lifting screw mandrel is because its keying stroke is long, and sealing also need be filled in screw mandrel top, leaks to prevent the generation on the screw mandrel, and grown service time, difficult sealing is with assurance, and maintenance is inconvenient.So the wasting of resources that leakage not long because of life of valve and that sealing causes causes is very big.

Based on the shortcoming of above-mentioned shutoff valve, this purpose of the utility model is to propose the hermetic shutoff valve of a kind of pottery, and the utility model adopts the pipe valve type, and valve rod only moves 1/4 to be changeed, and can reach control and open and close.

The purpose of this utility model is to realize like this; The ceramic full-sealing valve of forming by valve seat, valve body, valve rod, ceramic seal gasket, the sealing pair that ceramic seal moving valve plate and ceramic quiet valve block are formed is a cut-off gate, moving valve plate is that seam connects with valve rod, the turn valve rod can drive the identical angle of moving valve plate rotation, a runner is arranged, two through holes on the quiet valve block on the moving valve plate, when the runner on the moving valve plate is corresponding with two through holes on the quiet valve block, valve opening, when runner and through hole dislocation, valve is in cut-off state.

Accompanying drawing and drawing explanation:

Fig. 1 is a structure sectional view of the present utility model.

Fig. 2 is moving valve plate of the present utility model and quiet valve block view.

Fig. 3 is moving valve plate of the present utility model and another view of quiet valve block.

1---valve body; 2---valve rod; 3---moving valve plate

4---quiet valve block 5---valve seat; 6-sealing gasket;

7---the moving valve plate runner; A---import; B-outlet;

Below in conjunction with accompanying drawing and drawing explanation the utility model is described in further detail:

Valve body 1 is connected with valve seat 5, quiet valve block 4 is to be fixed on valve seat 5, establish a sealing gasket 6 below the quiet valve block 4, valve rod 2 is positioned valve body 1, valve rod 2 connects with moving valve plate 3 by seam, rotary valve rod can drive moving valve plate 3 rotations, because moving valve plate 3 and quiet valve block 4 are formed a sealing pair, runner 7 on import on the quiet valve block 4 and outlet B and the moving valve plate 3 forms the runner of a valve, when runner 7 misplaced with import A and outlet B, valve was in cut-off state, this scheme that the utility model adopted, the friction part only is a valve block, because of valve block is to adopt stupalith, can reach more than 300,000 times working life, and valve body 1 and valve rod and moving valve plate connection place all do not have flowing medium, this is the reliability that has guaranteed sealing on the structure, and this is that the valve of other structures is beyond one's reach.

In sum, the utility model structure is very simple, reduced sealing part widely, valve block adopts stupalith, and is not only wear-resisting but also corrosion-resistant, high temperature resistant again, make water tap with this structure, can make things convenient for citizen widely, both can make cold water faucet, can do the hot water tap again, a kind of novel replacement water tap of can yet be regarded as.

Claims

The pottery full-sealing valve is made up of valve body, valve seat, valve rod, ceramic seal valve block etc., it is characterized in that; The sealing pair that ceramic seal moving valve plate and the quiet valve block of ceramic seal are formed is a cut-off gate, and moving valve plate is that seam connects with valve, and a runner is arranged on the moving valve plate, two through holes are arranged on the quiet valve block, quiet valve block is to be fixed on the valve seat, and moving valve plate is by valve rod, the valve body location.
