Description

Foot control standard water tap

The utility model belongs to a kind of feed-water valve that feedwater piping is installed.

The feed-water valve of installing on feedwater piping at present generally is made up of handle, valve rod, valve body, valve plug etc., adopts manually rotation to wait and closes valve plug, closes feedwater thereby reach, thereby can not close feedwater automatically, is not easy to use in unhygienic place.

The purpose of this utility model provides a kind of foot control standard water tap that can close water automatically and adopt foot-operated feedwater.

The purpose of this utility model is to realize like this, main member comprises the foot control standard water tap that valve body, valve rod, valve plug and pedal are formed, its valve body comprises pipe 5 and is positioned at both sides and water inlet pipe mouth that communicates with it and effluent pipe mouth, its structural feature has the valve rod hole 8 that valve rod 2 is just passed for the upper wall of pipe 5, the pipe lower wall that valve rod is relative is therewith also opened a plug holes 9, and this hole can make valve plug 3 just pass and valve plug can slide up and down in this hole; Valve plug is bigger than valve rod hole, and the valve plug lower end is provided with the size plug 14 bigger than plug holes, and the valve plug upper end is connected in the valve rod lower end, and the valve rod upper end is connected on the pedal 4; Pass valve rod hole and be positioned at the valve rod 2 outer sleeve pipes 10 that are with of managing on the upper-end surface, this sleeve pipe lower end is fixed on the pipe 5, valve rod in the sleeve pipe is with seal ring 11, the bolt 12 that is complementary with aperture and valve rod be inserted in valve rod again with the sleeve pipe inboard by being threaded to seal seal ring 11, manage 5 upper-end surfaces sleeve pipe and on valve rod be with Returnning spring 13 jointly, the Returnning spring lower end is pressed in pipe 5 upper-end surfaces, and the upper end withstands on the pedal lower end surface; Pipe 5 lower ends that are positioned under the plug holes are provided with airtight plug cavity 15, and plug places in it and can slide up and down in this cavity.

The utility model because adopt strength of one's legs or gravity trampling pedal control feedwater and decontrol strength of one's legs then valve rod be subjected to the effect of return spring elastic force and return makes valve plug close the water route again, stop to supply water; Thereby be applicable to and needn't use the hand switch water tap in the public place, just can reach and open and close the water route, hygienic and convenient like this.

Below in conjunction with drawings and Examples the utility model is described in detail:

Accompanying drawing is a structural representation of the present utility model.

As shown in the figure, valve body 1 is made up of straight tube 5, its both sides are respectively into water port 6 and water outlet port 7, a valve rod hole 8 is opened in straight tube 5 upper-end surfaces, also open a plug holes 9 with it over against the lower end, valve plug 3 links to each other with valve rod 2 lower ends, valve plug has the plug 14 bigger than plug holes, welding or disjunctor are cast with valve rod sleeve pipe 10 on the straight tube 5, straight tube 5 bottoms and sleeve pipe 10 opposite positions are welded with or disjunctor is cast with plug cavity 15, valve rod is linked to each other through valve rod hole valve plug in it to the straight tube by sleeve pipe 10, valve plug and plug can be made into one, and valve plug can slide up and down in straight tube and in the plug cavity, and valve plug can be blocked the straight tube inner chamber, plug can not slip in the straight tube, can only move up and down in the plug cavity; Be with rubber sealing ring 11 between valve rod and sleeve pipe, flow out from valve rod hole to prevent water, valve rod is inserted in bolt 12 and is threaded onto then on the sleeve pipe, prevents that sweet seal breaks away from; The valve rod on sleeve pipe and sleeve pipe top is with Returnning spring 13 jointly, and valve rod top is connected with pedal 4, and the Returnning spring upper end withstands on the pedal, and the lower end is pressed on the straight tube, is enclosed within the outer Returnning spring of sleeve pipe and can entangles protection with an outer sleeve 16 again.Plug cavity 15 can be made with straight tube, can upwards insert valve rod, valve plug and plug during assembling, and then with pipe plug 18 this straight tube is blocked plug cavity 15 of formation; In addition, osculum 17 is opened in outer sleeve 16 bottoms, and ponding between outer sleeve and the Returnning spring is used to drain.When the utility model uses, depress pedal then valve rod drive valve plug and move downward, valve plug is not blocked the water channel of water intake and water outlet, thus water from the valve rod next door through flowing out by water outlet; When not pushing down pedal, pedal is replied under action of reset spring, and then valve rod, valve plug and plug move upward, and valve plug is blocked the water channel of water intake and water outlet, does not allow water be gone out by water outlet.In addition, for easy for installation, water intake and water outlet respectively are equipped with a union; Its effect of the plug of valve plug lower end is the control valve plug distance that moves upward, and plug cavity also control valve plug moves downward distance, prevents from that valve plug is whole to be pressed in the plug cavity, and the return difficulty makes it to move upward.
