Abstract

The utility model discloses an inner structure of a treadle controlled single treadle valve, comprising three parts of a valve body, a spool and a treadle, wherein the valve body composed of an upper and lower valve seat is equipped with the spool composed of a water outlet bar and a flexible sleeve, the flexible sleeve is equipped with a round hole which communicates water, the water outlet bar is equipped with a squared hole to pass water, the flexible sleeve is sleeved outside the cylinder of the water outlet bar. At mean time the squared hole on the water outlet bar is sealed by the flexible sleeve and the water cannot go by, when users tread a screw end on the middle of the treadle plate and press the flexible sleeve to push inside, make the round hole aligning the squared hole, water goes by the two holes and flow out from the water outlet hole. When finishing using, relax the treadle, the flexible sleeve is pushed outward pushed by a resetting spring inside the flexible sleeve, the squared hole is sealed by the flexible sleeve again, and the water flow is cut off. Compared with the sensor cock, the utility model has low manufacturing cost and is suitable for popular public spreading and using.

Description

Singly step on valve

Technical field

The utility model relates to the technical field of valve manufacturing of water supply line, be a kind of use in public places singly step on valve with what foot control system opened and closed.

Background technique

AT STATION, public place such as harbour, flow of personnel is frequent, before some public water supply stopcocks, the accident of cross infection of disease can take place in healthy people and suffer from the patient and use same water tap unavoidably.Some people wash receive and distribute after, secondary pollution can take place in the spanner that scruple goes to touch water tap with hand again, does not just go away so consciously or unconsciously do not turn off the tap, and valuable tap water resource is run off in a large number.The generation of this wasting phenomena is owing to there is not a kind of valve that just can close automatically that touches without hand.A kind of push button water tap is arranged on the market, during use as long as press with hand one, just can water outlet, spent several seconds after, the button on the valve can takeoff automatically and stop water outlet, need not go to the pass with hand, can be rated as convenient and practical.But this class valve also has shortcoming, be exactly that unsuccessful people of water outlet time is willing to, and the water yield is limited.In particular cases use also inconvenient at certain.Therefore the someone has invented inductive water tap again, and when user's hand during near the valve certain distance, water tap can automatic water outlet, as long as hand does not leave, current just can not stop.But the influence electricity magnet valve of its inside is subjected to power supply control.The useful Ac of power supply that uses, also useful galvanic, so its internal structure is comparatively complicated, and the manufacture cost height, installation difficulty is big, is not suitable for generally promoting in popular public place.

The model utility content

The purpose of this utility model is: the public place provides a kind of not manual water tap in society, with the cross infection that wards off disease, can accomplish water-saving purpose again simultaneously.

The technological scheme of the utility model technical solution problem is: replace manually with foot-operated, i.e. the unlatching of valve is controlled with pin.The utility model list is stepped on valve and is made up of valve body, spool and step three parts.Described valve body is fused by upper valve base and lower valve base and forms, and is intake tunnel between the last lower valve base.Described spool is made of water outlet bar and movable sheath, also comprises Returnning spring and rubber piston ring, and movable sheath is enclosed within water outlet bar cylinder outside.The head of movable sheath stretches out outside the valve body, is pressed on the lower valve base by gland nut; Described step becomes lever-like, and head is provided with the balance spring pin, also is provided with pin shaft hole and valve body and constitutes flexible connection and form balance pivot, and midpoint is provided with the screw top, and inconsistent with the movable sheath head, the step tail end is with anti-skidding rubber sleeve.

Described upper valve base front end is a water output connector, and fuse with the water outlet bar, the cylinder sleeve of described water outlet bar has Returnning spring, the one end withstands the valve cavity wall of upper valve base, the other end withstands the inner end of movable sheath, the inner end of water outlet bar is provided with a water flowing square hole, and the rubber seal sealing is arranged between water outlet bar outer end and the upper valve base.

The inner end of described movable sheath is provided with a water flowing circular hole, and be enclosed within outside the water outlet bar cylinder, the sealing of rubber piston ring is arranged between the two, accurate movingly between the outer end of movable sheath and the gland nut with sealing of rubber piston ring and formation, gland nut fixes by screw thread and last lower valve base, and the rubber seal sealing is arranged.

The bottom of described valve seat is provided with four fastening foot, and each fastening foot all is provided with a fixed hole.Described step is a lever in fact, and its front end is the Returnning spring that trimming moment is used, and the centre is the fulcrum that has bearing pin, and back segment is a wood clapper.The inner end of water outlet bar is provided with a square hole, and this square hole is entangled sealing by movable sheath at ordinary times.When the square hole alignment of the circular hole of movable sheath and water outlet bar, the water in the intake tunnel promptly enters water outlet bar inner chamber and flows out from the water outlet interface.The front end of described step is provided with the balance spring pin of trimming moment, is enclosed within an outer end and is provided with on the pin of block.Mid point in step is provided with adjustable screw top, and the head of movable sheath is directly withstood in the outer end.Afterbody pedal place in step is provided with the rubber sleeve that skids when preventing to trample.In addition, be equipped with rubber seal between water outlet bar and the uuper valve chamber and between the fastening nut of installation movable sheath and the valve body; Be provided with twice rubber piston ring respectively between the inwall of movable sheath and the water outlet bar cylinder and between the inwall of movable sheath outer wall and fastening nut, its effect all is to prevent to leak.

The utility model is owing to ride the unlatching of water tap by manually making into to use, electromagnetic induction is made into mechanical linkage open and close, therefore not only can prevent cross infection, using water wisely in use, manufacture cost is relatively low simultaneously, is worth promoting the use of in some popular public places.
