Abstract

The utility model relates to a self-closing water-saving valve, which is composed of a housing body, a closing cover, a sleeve, a rubber ring, a handle, a nut, a screw, a gasket, etc. The closing cover forms a hemispheric shape. When the self-closing water-saving valve is used, the closing cover is opened by a person pressing the handle, water can flow, and if the person loosens hishand, the closing cover can be automatically closed by the self weight of the closing cover. The utility model has the advantages of water saving and flexible and convenient use. The phenomenon that when the alternation that the water supply is cut off, and the water is supplied occurs, the waste caused by the opening of the valve can be resulted in can be prevented. The utility model can replace an original check valve an a ball valve; structure is simple and the cost is low. The utility model can be widely used for factories, institutions, families, and other public places.

Description

Self-closing water-saving valve

The utility model belongs to a kind of auto cut-off water saving valve.

At present, the auto cut-off water saving valve has various, patent 0211560.x self-closing link water valve for example, when patent 90220196.4 self-closing link water valves etc. use, can not close immediately, also have leakage phenomenon, the ideal of not enough water saving, and the ubiquity structure is complicated, cost is higher, also not enough economic dispatch shortcoming.

The purpose of this utility model provides a kind of water valve, using water wisely of closing automatically immediately by the deadweight of closing lid.

The utility model is by housing, close lid, sleeve, cushion rubber, handle, nut, screw, compositions such as packing ring, housing (1) has protuberance, handle (5) is housed on the protuberance, handle (5) is with nut (6), cushion rubber (4) links with valve shaft (3), valve shaft (3) is contained on the housing (1), valve shaft (3) has two steps, sleeve (11) is engaged between two steps, one end has the opening lockhole, can load onto hatch lock, close lid (2) and be hemispherical, its upper end cooperates with valve shaft (3) with the square endoporus, closes and uses screw (7) clamping washer (8) and cushion rubber (9) on lid (2) one planes, and there is screw thread at housing (1) two ends.

The utility model is simple in structure, and the functional reliability height is closed automatically by closing the lid deadweight, can economize on water, and has prevented to cut off the water when coming water to replace, and valve is not closed the tap water wasting phenomena that causes.Flexible and convenient to use, once by can, can replace original safety check and spherical valve, can be widely used in factory, office, family and other public place and use.
