Abstract
The utility model belongs to the technical field of controlling running water pipelines, which relates to the improvement of existing water supply systems. The utility model provides an automatic water saving valve for water cut-off is composed of a deflector rod, a light force return spring, a tapered piston, a pressure sensor of a sealing chamber, a water outlet pipe opening with automatic locking. The automatic closing of a water supply system after the water cut-off can be guaranteed, so that when water supply recovers after the water cut-off, running water can be prevented from flowing out automatically no matter whether a water tap is tightly screwed or not, and accordingly, the purpose of automatic water saving can be obtained. The utility model has simple structure, convenience and practicality, can be used for the existing water supply systems of daily life, and can also be used for the pipeline control of various kinds of fluid.
Description
The utility model belongs to tap water pipe line control technique field, relates to a kind of improvement to existing water system.
The frequent phenomenon of cutting off the water of water service in the daily life, the user forgets that the phenomenon of fastening water tap happens occasionally when cutting off the water, this makes and to cause unnecessary tap water waste when resuming water supply easily, also can bring a lot of inconvenience to life because of " floods " etc.
The purpose of this utility model is to overcome the above-mentioned deficiency of existing tap water supply system, providing a kind of can guarantee in the phenomenon of cutting off the water the device that the back is closed voluntarily to water system to take place, whether water tap is tightened tap water and can not flowed out voluntarily when guaranteeing to resume water supply after cutting off the water, and reaches the purpose of automatic water-saving.
Thinking of the present utility model is that a kind of water-saving valve by hydraulic pressure control of design is controlled feedwater, and the hydraulic pressure when this valve utilization is supplied water keeps water valve jack-up the water route unimpeded, and after cutting off the water, because hydraulic pressure disappears, water valve descends and blocks the water route.When supplying water once more, the pressure of water makes water valve continue to block the water route, and the water route is closed by self-locking.Have only after the people enables water valve, hydraulic pressure disappears on the water valve, and water valve just can be resumed water supply by jack-up.
Accompanying drawing 1 has provided a kind of realization structural representation of the present utility model
Among the figure:
1., driving lever 2., top cover 3., light power returning spring 4., the driving lever catch
5., pad 6., nut 7., slide cartridge 8., the flexible sealing rubber sleeve
9., upper cap nut 10., tapered piston (11), lower nut (12), self-locking effluent pipe mouth
(13), water saving valve seat
Describe the utility model in detail below in conjunction with accompanying drawing:
The utility model constituted cut off the water automatic water-saving valve by driving lever 1., light power returning spring 3., tapered piston 10., sealed volume pressure transducer, self-locking effluent pipe mouth form, a sealed volume pressure transducer on cutting off the water valve, this is housed, in the sealing cavity volume pressure transducer upper end of flexible rubber stuffing box gland by the driving lever washer 4., pad 5., nut being threaded between 6. link to each other with driving lever sealing extruding, 7. the lower end links to each other with valve body by sealing to push when being threaded with water saving valve seat (13) at slide cartridge.The sealed volume pressure transducer by the flexible rubber stuffing box gland 8., the driving lever catch 4., 5. pad form, can in slide cartridge, move up and down, top cover 2., slide cartridge 7., the water saving valve seat (13) connect by thread forms, slide cartridge when 7. connecting with water saving valve seat (13) is squeezed in the lower end seal ring of flexible rubber stuffing box gland middle, and is water-tight to guarantee.The driving lever catch 4., pad is 5. 6. water-tight to guarantee in the middle of being squeezed in the upper end seal ring of flexible rubber stuffing box gland by scyewed joint with nut, and like this, flexible rubber stuffing box gland, driving lever catch, pad are formed the sealed volume pressure transducer.Tapered piston 10. by last lower nut 9., (11) be fixed on the driving lever, self-locking effluent pipe mouth (12) is a cone structure, its tapering is consistent with the tapering of tapered piston, height is greater than tapered piston, the big mouthful of diameter in its top is greater than the maximum diameter of piston.When normal water supply, hydraulic action is on the Upper gasket of sealed volume pressure transducer, overcome the elastic force of light power returning spring, tapered piston carried draw, keep the water route unimpeded, when cutting off the water, hydraulic pressure disappears, under light power returning spring effect, tapered piston drops down onto in the taper mouth of pipe, blocks the water route, after resuming water supply, all effect has hydraulic pressure on the pad of pressure chamber and tapered piston upper surface, but, thereby act on pressure on the tapered piston greater than the pressure on the pad, the effect of light power returning spring in addition because the upper surface area of tapered piston is greater than the pad area, piston can not be mentioned automatically, thereby realization water route self-locking is closed.When the user wants water after resuming water supply,, mention tapered piston, just can make water-saving valve be in normal unimpeded water supply state, up to cut off the water next time as long as with portable driving lever once.
The utility model is simple in structure, and is convenient and practical, can be widely used in the water system in the present daily life, also can be applicable in the pipeline control of all kinds of fluids.
Claims (2)
1, a kind of automatic water-saving valve of cutting off the water with driving lever, tapered piston, form by driving lever, light power returning spring, tapered piston, sealed volume pressure transducer, self-locking effluent pipe mouth, it is characterized in that on driving lever, being equipped with a sealed volume pressure transducer, the upper end of flexible rubber stuffing box gland links to each other with driving lever sealing extruding by being threaded between driving lever catch (4), pad (5), nut (6) in the sealing cavity volume pressure transducer, and the lower end links to each other with valve body by the sealing extruding when being threaded with water saving valve seat (13) at slide cartridge (7).
2, water-saving valve as claimed in claim 1 is characterized in that the self-locking effluent pipe mouth is a cone structure, and its tapering is consistent with the tapering of tapered piston, highly is slightly larger than tapered piston, and the big mouthful of diameter in its top is greater than the maximum diameter of piston.
