Description

Touch and press the quick urinal flushing valve of water saving

The utility model relates to mechanical engineering, and specifically a kind of touching pressed the quick urinal flushing valve of water saving.

A large amount of at present urinal flushing water regulator tools that use are traditional stop valve, it is the switching that comes controlled water flow by the spinning in and out of handwheel (handle), its control operation process is long, use very inconvenience, and the wastage of water is big, between its each member side-friction is widely arranged all, and be operated in the pressure medium, thereby spoilage is high.CN2094663, CN2102420 disclose " push button delay time adjustable Self-closed water valve ", " push button delay-self-closing valve " respectively, though their control operations are comparatively simple, but still need bigger operating physical force, and and manufacturing process complexity, penetration and promotion, practicality are relatively poor.

It is comparatively simple that the purpose of this utility model provides a kind of structure, good seal performance, and long service life, cost is low, and operation touching quick and portably pressed the quick urinal flushing valve of water saving.

The utility model is to be made of valve body, elastic packing diaphragm, Pit cover, moving iron core, obstruction piece, pressing plate, spring, permanent-magnetic clamp, valve gap, button.The Y-shaped perforation of inlet and outlet channel is in valve body, elastic packing diaphragm vertical means in valve body is separated in the upper end of outlet passage and with valve pocket, following two chambeies, have epicoele inlet opening and epicoele drain hole on the elastic packing diaphragm, chamber is placed on and is connected on the valve body by pressing plate in the valve gap and is crimped on the elastic packing diaphragm, moving iron core head is in the tube of the central garden of Pit cover, the last end device of moving iron core has spring, the lower end of moving iron core is connected with to be stopped up piece and stops up the epicoele drain hole upside that piece is positioned at elastic packing diaphragm central authorities, permanent-magnetic clamp is actively socketed on the Pit cover central authorities garden tube, main return spring is in being socketed between permanent-magnetic clamp lower end and pressing plate on the Pit cover central authorities garden tube, valve gap is connected on the pressing plate that is fixed on the valve body, and the button head is in valve gap.

The utility model has been abandoned the form of structure of conventional valves, the lifting that utilizes the magnetic attraction of permanent-magnetic clamp to control moving iron core makes stops up piece and opens or closes epicoele drain hole on the elastic packing diaphragm, change the pressure reduction of upper and lower chamber, and then realize opening and closing of delivery port.It is simple in structure, and isolated controlling is operated very lightly, and rapidly opened and closed current avoid waste, and have significant water-saving result; It does not have the side-friction and the damage of each member in the work, and its controlling organization and executing agency isolate fully and be operated in the environment that does not have pressure outside the medium, thereby its sealing characteristics is good, long service life.Its valve body, valve gap, Pit cover, pressing plate, button etc. all can adopt thermoplastic shot moulding, can save a large amount of metal material and exempt process and the expense that traditional casting all need be carried out secondary operations, and cost is low, and manufacturing process is simple.
