Description
Technical field:
The present invention relates to a kind of valve, particularly a kind of float valve.
Background technique:
Be used for the float valve that water tower etc. locates at present and form by ball float, support, rotating shaft, rubber gasket etc., because unlatching face relies on rubber seal, ageing-resistant ability, yielding, instability at high temperature can't be worked; Do not have the location vertically and radially, make and close the end face out of plumb, discontinuity needs bigger strength just can close so close end face; Because unreasonable structure causes poor sealing performance, can not bear higher hydraulic pressure, easily leak, so working life is short.
Summary of the invention:
The present invention solves existing float valve poor sealing performance, unreasonable structure, job insecurity, short problem of life-span, designs a kind of good seal performance, working stability, high temperature resistant, float valve that the life-span is long.
Technological scheme of the present invention is such: it comprises valve body, rotatingshaft, pass through the friction tight ball float of connecting sleeve with described rotatingshaft upper end, described two ends of valve body is respectively water intake and water outlet, described side of valve body is provided with the upper valve body that is communicated with described water intake and water outlet, the shell of described upper valve body is the cylindrical shape lock nut that a bottom is communicated with described water intake, described rotatingshaft probes in the described lock nut, the part that rotatingshaft is positioned at lock nut is provided with a location step, between described lock nut in the top of described positioning step and rotatingshaft, be provided with and the friction tight mobile gasket of rotatingshaft, described mobile gasket is provided with static gasket, and described static gasket is provided with axle sleeve; The bottom of rotatingshaft is fixed with a direction fixed base in the described lock nut, be connected with a moving valve on the described direction fixed base, described moving valve is provided with has a moving valve breach at least, and the bottom of described moving valve is provided with a quiet valve that cooperates with described moving valve, and described quiet valve is provided with at least one quiet valve through hole; The lower side of the described cylindrical shape lock nut position corresponding with described moving valve is provided with the water outlet through hole that at least one is communicated with described water outlet, its bottom is provided with a ring-type pretension rubber base, its underpart inner side surface is provided with the screens of the described quiet valve radial motion of restriction, and the position that its inner side surface is corresponding with described direction fixed base is provided with restriction protrusion.
Above-mentioned moving valve breach is symmetrically arranged with two on described moving valve, described quiet valve through hole also is symmetrically arranged with two, and described water outlet through hole correspondence is symmetrically arranged with two.
Above-mentioned symmetrically arranged moving valve breach is a triangle, and described quiet valve through hole is can be fan-shaped with the triangle that moving valve cooperates, and described quiet valve through hole also has inclined table.
Above-mentioned screens is a draw-in groove, and the circumference of described quiet valve is provided with the prism corresponding with described draw-in groove.
Above-mentioned screens is the card rib, and the circumference of described quiet valve is provided with and the corresponding draw-in groove of described card rib.
Above-mentioned connecting sleeve is connected by regulating arm with described ball float.
Above-mentioned connecting sleeve is connected by hook with described ball float.
Above-mentioned pretension rubber base neutral position vertically is provided with a C shape bullet circle.
Above-mentioned moving valve, quiet valve and mobile gasket and static gasket all adopt pottery to make.
The excircle on the water outlet through hole top of above-mentioned lock nut is provided with the outside thread that matches with valve body, and described outside thread ends at the terrace with edge that is provided with on the described lock nut excircle, and described terrace with edge bottom surface and valve body joint are provided with a pad.
When the present invention floats when ball float, leverage drive rotatingshaft by regulating arm rotates, because the direction fixed base of rotatingshaft bottom is subjected to the restriction of projection, the rotation of rotatingshaft is limited, the strength of ball float come-up is transformed into continuation to the downward thrust of rotatingshaft by regulating arm or hook transmission, rotatingshaft is rotated down, the feasible moving valve that is rotated down with rotatingshaft is axially tightly being fitted with quiet valve, radially also be positioned, this moment, moving valve breach and quiet valve through hole staggered each other, moving valve breach and water outlet through hole also stagger, the present invention is in closed condition, and because quiet valve is the face contact with contacting of moving valve, and water intake pressure is big more, quiet valve is tight more with contacting of moving valve; The setting of static gasket and mobile gasket and axle sleeve both can have been prevented the seepage of sealing, can accurately accurately locate again, reduced incrustation scale and entered, and also can prevent rotatingshaft and the wearing and tearing on the surface that respectively is rotatably assorted, and prolonged working life of the present invention; Advantages such as moving valve, quiet valve, mobile gasket and static gasket all adopt pottery to make, and have eliminated original float valve and have been subjected to the aging influence of seal rubber pad and the defective of non-refractory, have long service life, and be not yielding.The C shape bullet circle that pretension rubber base neutral position vertically is provided with can support the pretension rubber base, makes its unlikely distortion and unlikely seepage that causes sealing surface under bigger hydraulic pressure.So the present invention has good seal performance, working stability, high temperature resistant, advantage that the life-span is long.
