Abstract

The utility model relates to a foot feed valve consists of a feed valve and a foot switch. A steel rope is equipped between the foot switch and the valve trim of the feed valve. The steel rope is provided with a rope sheath outside. The utility model has a simple structure, a low cost; is safe and sanitary because the switch of the feed switch is not touched with hands when in use; avoids in wasting the water source because the feed valve can automatically turned off after finishing in the use; also can freely control the water quantity.

Description

Pedal water valve

Technical field

The utility model relates to water valve, specifically is a kind of pedal water valve.

Background technique

At present, known Water tap is to turn round with hand, and people must catch and touch water tap, but the sanitary condition of water tap is worth worry again, germ on hand is easy to by water tap propagation, the especially water tap of public place, and easier intersection is propagated.In addition, some people does not treasure water resources, uses up untimely pass water supply valve behind the water, under the situation of cutting off the water, is easy to forget and closes water valve that the people leaves water afterwards, can cause big water gaging waste.

Summary of the invention

In order to overcome existing water valve above shortcomings, the utility model provides a kind of pedal water valve, and this water valve need not catch and touch water valve, and using the back water valve can close automatically.

The utility model pedal water valve comprises water valve 100 and foot switch 50, and steel cable 7 is installed between the pedal 51 of described foot switch 50 and the spool 10 of water valve 100, and rope sling 8 is arranged outside the steel cable 7.

This pedal water valve is simple in structure, cost is low, must not catch during use and touch valve switch, and safety and sanitary use the back water valve and close automatically, have avoided the waste of water resources, and the big I of the water-outlet quantity of this water valve is freely controlled in addition.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, this pedal water valve comprises water valve 100 and foot switch 50, and steel cable 7 is installed between the pedal 51 of foot switch 50 and the spool 10 of water valve 100, outside the steel cable 7 rope sling 8 is arranged, and described spool 10 is made up of hollow rubber valve pocket 2, valve rod 3 and Returnning spring 4.

Described water valve 100 comprises three way valve 1 and the hollow rubber valve pocket 2 that is installed in three way valve 1 inner chamber, wherein, as shown in Figure 2, the upper end of this three way valve 1 is a water outlet, the right-hand member of three way valve 1 is a water intake, the lower end of three way valve 1 is the mount inlet of described spool 10, the mount inlet of the described valve body 1 lower end valve gap 5 that is spirally connected, the seal ring of described hollow rubber valve pocket 2 lower ends is pressed between valve gap 5 and valve body 1 lower end surface, valve rod 3 is installed in the valve pocket 2, valve rod 3 epimeres are provided with Returnning spring 4, the hypomere of valve rod 3 passes the through hole of valve gap 5, valve rod 3 lower ends are the upper end of steel cable 7 fixedly, the valve gap 5 lower ends upper shield 6 that is spirally connected, and upper shield 6 is provided with and rope sling 8 matched cylindrical grooves.

Described foot switch 50 comprises pedal 51 and underframe 52, the latter half of foot pedal cover 54 that restriction pedal 51 positions are set of underframe 52, and the guide rod 53 on pedal 51 and the underframe 52 is fixed the lower end of described steel cable 7 movingly on the pedal 51.

For the ease of regulating max water yield, the described rope sling 8 of present embodiment is provided with water yield adjusting screw 9 in underframe 52 1 sides of foot switch 50, nut 11 screw-thread fit on water yield adjusting screw 9 and the described underframe 52.

The control principle of this pedal water valve is as follows:

Push down on the pedal 51 with tiptoe, steel cable 7 pulling connecting rods 3 drive valve pockets 2, make between the inboard of valve pocket 2 upper ends and valve body 1 water outlet and produce the space, and current from then on space flow to external water tap through water outlet again; Pin unclamps, and spring 4 promotes connecting rod 3 drive valve pockets 2 and resets, the inboard driving fit of valve pocket 2 upper ends and valve body 1 water outlet, and current end.

The positioning control current size that this pedal water valve can be depressed by pedal 51 specifies its using method below in conjunction with Fig. 3～5:

During concrete the use, the foot switch 50 of this pedal water valve is installed on the floor, water tap below is convenient to the position that tiptoe is stepped on, the water intake of described water valve 100 is connected with intake pipe, the water outlet of described water valve 100 is connected to water tap.As shown in Figure 3, under the normal state, pedal 51 is in topmost, and the inner seal of valve pocket 2 upper ends and valve body 1 water outlet does not have water to flow out this moment; When the less current of needs, as shown in Figure 4, pedal 51 half is pressed, produce less space between the inboard of valve pocket 2 upper ends and valve body 1 water outlet, less water outflow is arranged; When the bigger current of needs, as shown in Figure 5, under pedal 51 total heads, produce maximum interspace between the inboard of valve pocket 2 upper ends and valve body 1 water outlet, there is this moment bigger water to flow out.
