Abstract

The utility model relates to a foot board type flashing valve which is mainly composed of a valve body, a steel ball, a trapezoid elastic sealing component and a foot board. The inner side of the upper end of the valve body is inlaid with a stainless steel sealing ring. The outer side of the upper end of the valve body is provided with outer screw threads. The middle of the upper end of the valve body is provided with a water inlet hole. The steel ball is arranged on a water inlet hole to make the water not leak. The underside of the valve body is provided with a half-through hole with inner screw threads and the bottom of the valve body is a U-shaped gutter. The trapezoid elastic sealing component is installed in the middle position of a push rod and is arranged in the inner hole of a lower cover. One end of the push rod can drill out of the bottom hole of a lower cover and can be connected with the foot board. The other end of the push rod is inserted into the central half-through hole of the steel ball. The utility model has the advantages of reasonable structure, long service life and good water saving effect, and is suitable for shower for various units.

Description

Foot-board type flashing valve

Employed pedal plate type shower in the constituent parts bathroom at present, all be to adopt the flushing valve of pedal chain pull type, this valve body is to make sealing gasket with sheet rubber, opens by spring force, and sheet rubber is through the flexible repeatedly extruding of spring, be easy to rotten the damage, and spring ducks in drink for a long time, gets rusty easily, and elasticity is reduced, even lost efficacy, shortened working life.

The purpose of this utility model is in order to provide a kind of working life long pedal plate type water saving flushing valve.

The flushing valve of this pedal plate type, mainly by valve body, foot treadle, post is threaded, connecting rod, trapezoidal elastomer seal, seal ring, steel ball, push rod, loam cake, lower cover and attaching nut form, the stainless steel seal ring is inlayed in the inboard on it is characterized in that valve body, there is outside thread in the outside, there is the water inlet centre, steel ball is placed on the water intake of upper end stainless steel seal ring of valve body, open tapped half a pass-out water hole at the downside of valve body, this half pass-out water hole communicates with water inlet in the middle of the valve body, the valve body bottom is for Jiong shape groove shape and a central small hole is arranged, there is internal thread inboard at Jiong shape groove, there is the tapped water inlet through hole of a upper and lower end at the center of loam cake, the upper end in the loam cake outside is a hexagonal shaped, there is a round platform inside, the internal thread of loam cake lower end cooperates by the outside thread of seal ring with the valve body upper end, the internal thread aperture of loam cake upper end is less than the diameter of steel ball, steel ball can not spilt from the hole, one end of push rod has outside thread, be equipped with one in the cardinal principle interposition and be with externally threaded boss platform, the trapezoidal elastomer seal that has center hole, penetrate on the boss platform of push rod by its center hole, and fix with nuts and washers, there is endoporus lower cover inside, the bottom that is contained in the trapezoidal elastomer seal on the push rod is in the endoporus of lower cover, its circular edge is in the Jiong shape groove of valve body bottom and seals, one small through hole is arranged at the bottom of lower cover, the lower end of push rod passes lower cover bottom small through hole, the lower cover that assembles is contained in the bottom Jiong shape groove of valve body by its outside thread, the upper end of push rod penetrates the central small hole of valve body Jiong shape groove simultaneously, and enter in center half through hole of steel ball, lower end at push rod is connected with connecting rod by the attaching nut, the lower end of connecting rod connects the post that is threaded, the post lower side that is threaded has a pin-and-hole, and the front end of foot treadle is connected with the post that is threaded by bearing pin.

Below in conjunction with accompanying drawing structure characteristic of the present utility model is further specified:

Accompanying drawing is a structural representation of the present utility model, and wherein valve body 5 adopts steel to make, and stainless steel seal ring 3 is inlayed in its inboard, upper end, not easy to wear, valve seal is good, long service life, steel ball 2 adopts hard metal material to make, there is half through hole the centre, through Nickel Plating Treatment, and cooperates tightly water-tight with stainless steel seal ring in the valve body 5, trapezoidal elastomer seal 7 adopts rubber material to make, main spring and seal action, non-corrosive, the long service life of rising.Loam cake 1, push rod 4, lower cover 10, connecting rod 12, post 13 and the foot treadle 14 that be threaded are common metal spare, can make with reference to accompanying drawing and feature thereof, and nut 9, packing ring 8 and attaching nut 11 are known.

The utility model in use as shown in the figure, the upper end internal thread by loam cake 1 is connected with intake pipe, outlet pipe is connected in the half pass-out water hole 6 of valve body 5 sides.Foot treadle 14 can adopt known, when shower person sets foot on foot treadle 14, just can lift an end of foot treadle 14 by human body self weight, push rod 4 is lifted on also, and compress trapezoidal elastomer seal 7 in the middle of it, push rod 4 is also with steel ball 2 jack-up simultaneously, make steel ball 2 leave the water inlet of valve body 5, water in the intake pipe can flow out from outlet pipe automatically, after shower person gets off from foot treadle 14, trapezoidal elastomer seal 7 by push rod 4 middle parts is with push rod 4 pop into position, and steel ball 2 is got back to original position by the pressure of weight own and water, and the water intake of stainless steel seal rings 3 stops flowing water in the valve body 5.

The utility model is rational in infrastructure, and each part is not fragile, and long service life is better by water-saving result on probation, than the general manual water pipe valve 35-40% that can economize on water, is fit to the constituent parts shower and uses.
