The foot control valve 1 that this product uses comprises to be brought into; delivery port 51; 52 application valve body 5; be installed with panel 58 on the described application valve body 5; be set with on the panel 58 can move up and down step on button 57; describedly advance; delivery port 51; 52 respectively with application valve body 5 on; lower chamber 53; 54 communicate; two cavitys 53; be provided with limbers 55 between 54; described upper cavity 54 is that three layers of diameter become big ladder cavity according to this; bottom is equipped with pressure ring 6; described pressure ring 6 is provided with and guarantees that limbers 55 and delivery port 52 keep the groove 61 that communicates; the intermediate layer is equipped with sealing mat 7; described sealing mat 7 is pressed on the upper cavity end face by locking swivel nut 71; thereby guaranteed that current can not flow out from stepping on button 57; top layer end face and step on and be provided with spring 72 between the button 57; spring 72 effectively will be stepped on button 57 and remain on highest order; but described stepping on is connected with the push rod 56 of roof pressure on sealing mat 7 on the button 57; T type push rod 8 is installed in the described lower chamber 53; T type push rod 8 one ends pass limbers 55 and contact with pressure ring 6; the other end is pressed on the end face of limbers 55; the bottom of lower chamber 53 is sealed and installed with bottom 9; be provided with back-moving spring 91 between bottom 9 and the T type push rod 8; the design makes under original state; on; lower chamber 53; 54 isolate mutually; seal more reliably in order to make between T type push rod 8 and limbers 55 end faces; can between them, be provided with rubber pad 81; the utility model is not limited to above-mentioned foot control valve 1 form of structure; can also use other common control valve structure; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model in a word.

With reference to figure 5, when this product is installed, at first the application valve body 5 with foot control valve 1 is inlaid in underground, and panel 58 is equal with ground, water inlet 51 on the foot control valve 1 links to each other with the control mouth 33 of main valve 2 by water pipe, and the delivery port 31 on the main valve body 3 is connected with depotition cock or flushing valve, and water inlet 32 is connected with water inlet pipe.

Operating principle of the present utility model is: during original state, water inlet pipe supplies water for main valve body 3 from the water inlet 32 on the main valve body 3, current flow into from the through hole 46 on the sealing staving 4, because sealing staving 4 inwalls are provided with water passing groove 47, thereby make sealing staving 4 interior storage full waters, and buoyancy aid 41 is on the water inlet 44 that is being pressed on sealing staving 4 under the pressure of hydraulic pressure and spring 43; Simultaneously, owing to be connected by water pipe between main valve 2 and the foot control valve 1, make and also store up full water in the lower chamber 53 of foot control valve 1; When needs are washed by water, pin trampled stepping on the button 57, make that stepping on button 57 moves down, simultaneously, the push rod of stepping on the button 57 56 passes through sealing mat 7, pressure ring 6 makes T type push rod 8 to moving down, thereby make T type push rod 8 leave limbers 55 end faces, at this moment, on, lower chamber 53,54 connect mutually, water in the sealing staving 4 flows out from control mouth 33 through delivery port 45, thereby flows to upper cavity 54 through the limbers 55 on the foot control valve 1, and flows out from delivery port 52, move downward so buoyancy aid 41 overcomes the pressure of spring 43 under the pressure of hydraulic pressure, thereby make current to flow to water tap or flushing valve from the delivery port 31 of main valve body 3; When pin leaves when stepping on button 57, the elastic force of spring 72 will be stepped on button 57 and remain on highest order, and T type push rod 8 cuts out under the pressure of back-moving spring 91 and hydraulic pressure automatically, returning to original state isolates upper and lower cavity 53,54 mutually, at this moment, current slowly will seal staving 4 by water passing groove 47 and fill with, thereby make buoyancy aid 41 time-delays be pressed on the water inlet 44 of sealing staving 4, stop water outlet.

This product adopts the split design with foot control valve 1 and main valve 2, realize the automatic switch of main valve 2 by the keying of foot control valve 1, in addition, adopt split-type design to make that foot control valve 1 volume is less, can install with burying, the utility model is simple in structure, use and install comparatively convenient, thereby be widely used on the products such as tap, flushing valve, particularly on the sanitaryware of public place.
