Description
Technical field
The utility model relates to the antifouling mechanism of a kind of valve.
Background technique
It is large that pressure difference inlet valve sealing principle is that Area Ratio that waterstop pad is positioned at back pressure cavity one side is positioned at the area of intake tunnel one side, when sealing, back pressure cavity pressure equals intake tunnel pressure, because area official post Pressure in Back-pressure Cavity is greater than intake tunnel pressure, waterstop pad can press and realize sealing toward sealing face.In this process, need control intake tunnel to flow to the water velocity of back pressure cavity.In the middle of the water inlet of existing border, waterstop pad structure control intake tunnel to the mode of the water velocity of back pressure cavity of water outlet probably has two kinds: the one, control water velocity by the size of controlling the through flow hole on sealing assembly; Another is that gap length by controlling a cleansing pin and through flow hole is controlled water velocity, and this cleansing pin and the compression of spring one are fixed in back pressure cavity.
And the problem that aforesaid way produces is: control current if directly control through flow hole size, require through flow hole cross sectional area relatively little, therefore in use easily blocked by the particulate such as sand, dust, make it ineffective, be presented as not sealing phenomenon of inlet valve, particularly use this inlet valve in the poor place of water quality, the blocked situation of through flow hole is more serious; If adopt the fit system of spring cleansing pin part and through flow hole, through flow hole and cleansing pin part meeting relative movement in water inlet, sealing process, therefore through flow hole is not subject to the particulates such as the grains of sand and blocks, but because spring has pretightening force, cleansing pin part can only move in the axial direction with respect to through flow hole, in assembling or using process, easily make cleansing pin and through flow hole bias cause both frictions larger, can reduce working life and cleansing pin part and through flow hole can be stuck and cause inlet valve inefficacy.
