Description

Quantitative self-closing valve

Technical field

The utility model belongs to water supply valve field, and in particular to a kind of quantitative self-closing valve.

Background technology

When at present using running water cannot quantitative automatic turn-off, when discharging water must someone guard, otherwise easy spill-over metals run out, Cause to waste；With the constantly improve of water system, although tap water cut-off is existing as seldom occurring, the reasons such as maintenance are met Cut off the water and be still difficult to avoid that, people easily forget to be turned off after opening water halter when cutting off the water, or deliberately do not close water halter, The sound for having flowing water during etc. water just knows water, but it is busy go out or also easily ignore water halter during sleep do not have pass, So water when just easily cause to metal run out the generation of existing picture, therefore the phenomenon of metalling run out that reason is caused is not uncommon for, and not only wastes water Resource, can also cause damage to the house of neighbours downstairs, furniture etc., and economic loss is larger, it is also possible to influence neighbourhood harmonious.

The content of the invention

The purpose of this utility model is the above mentioned problem in order to solve to exist using running water at present, there is provided one kind is quantitative Self-closing valve, its technical scheme is as follows：

A kind of quantitative self-closing valve, it includes straight-through valve body, water inlet tube interface is respectively arranged with the two ends of straight-through valve body With water outlet interface tube, vane type water flow rotary drive device, deceleration transmission are disposed with along current direction in straight-through valve body Gear train and automatic switch, vane type water flow rotary drive device are connected by under drive gear group with automatic switch, by Flowing water provides power and automatic switch is controlled, and realizes quantitatively discharging water by the speed reducing ratio for setting under drive gear group；From Dynamic switch includes valve plate, switch gear, one-way transmission gear and driving gear, is sealed between valve plate and straight-through valve body and the company of fixation Connect；Switch gear, one-way transmission gear and driving gear are arranged on a side surface relative with water inlet tube interface of valve plate, actively Gear is fixedly connected with the output end wheel shaft of under drive gear group, and switch gear, one-way transmission gear and driving gear are successively Power is reached driving tooth by ratcheting connection, vane type water flow rotary drive device when being impacted by flowing water through under drive gear group Wheel, then switch gear is reached through one-way transmission gear, switch gear is rotated when there is the condition of current；In straight-through valve body Axle stand is inside additionally provided with, for the wheel shaft of fixed gear, axle stand is fixedly connected with straight-through valve body or is fixedly connected with valve plate； The surface that valve plate is in contact with switch gear is smooth surface, is provided with the hollow out of circular arc on switch gear, hollow out around The axial line of switch gear is set, and a discharge orifice is provided with valve plate, and discharge orifice is arranged on the rotary motion trace of the hollow out It is interior, and the coverage of the Delta Region between hollow out two ends of switch gear is more than discharge orifice, switch gear rotation To hollow out with discharge orifice communicating state when water can pass through, i.e. switch open condition, switch gear is rotated to Delta Region covering Current, i.e. switch closed condition are blocked during the state of discharge orifice, and tight closure is kept under hydraulic pressure effect, in the trigonum A diameter is provided with domain less than one millimeter of micropore, makes the switch closed condition water can be with seepage, faint water under leakage states Raw power of miscarrying is less than the frictional resistance of each link, and vane type water flow rotary drive device cannot start, and now blocks straight-through The water outlet interface tube of valve body, such as close the water halter for being arranged on outlet pipe interface, as the water of seepage is cumulative, leads directly to Pressure balance in valve body, because the Delta Region side of switch gear is heavier, can go to Delta Region under the effect of weight power The sagging state in side, you can open switch with using gravity；Valve plate uses stainless steel or copper or plastics material with switch gear Matter, is prevented from getting rusty, and counterweight is set in Delta Region using the switch gear of plastic material, sagging to accelerate；By straight-through valve body with When tap water pipeline is connected, discharge orifice will be located at the oblique upper of the wheel shaft of switch gear, to ensure the Delta Region of switch gear Switched during hang and opened；One-way transmission gear is only driven from driving gear to switch gear, the wheel shaft of one-way transmission gear It is arranged in the axis hole of circular arc, the axis hole of circular arc is set around the axial line of driving gear, makes Delta Region smoothly sagging.

The beneficial effects of the utility model are：The water inlet tube interface of straight-through valve body is connected with tap water pipeline, straight-through valve The manually-operated gates such as the water outlet interface tube of body and water halter are connected, and when opening water halter and discharging water, switch gear is rotated, deceleration transmission tooth The speed reducing ratio of wheel group determines the shut-in time of automatic switch, and realization is quantitatively discharged water, it is possible to use the deceleration of different speed reducing ratio is passed Moving gear group produces the automatic valve of different basis weights；Because can be automatically switched off, forget also not resulted in greatly when closing water halter Amount is metalled run out, and reduces economic loss；Close after water halter, automatic switch can fast automatic opening.
