A spring control device is connected between a valve body and a handle; the spring control device is composed of two second springs and four pull rods; the two second springs are symmetrically arranged bilaterally relatively to the handle; each one of two ends of each second spring is connected with one pull rod, wherein two first pull rods are fixedly connected with the inner side face of the valve; two second pull rods are fixedly connected with the handle; a water flow sensing probe is arranged at the position of a water flow outlet of a pipeline; the water flow sensing probe is connected with a time controller outside the pipeline; the time controller is connected with a motor and the motor is fixedly connected with a gear; one end of a thin steel wire is tied on the gear and the other end of the thin steel wire is connected with a plug; the plug is arranged in a groove on the side wall of the handle and the plug is further connected with one end of a first spring; and the other end of the first spring is fixedly arranged on the outer wall of the pipeline. When water flows through the water faucet for a period of time and a user forgets to close the water faucet, the automatic water braking valve can automatically stop the water and is simple and feasible to operate.

Description

A kind of automatic shutoff valve

Technical field

The present invention relates to a kind of water valve structure that is applied on the water tap, refer in particular to a kind of water valve of ability automatic shutoff.

Background technique

At present, the water valve of automatic shutoff commonly used mainly contains following several kinds: the automatic shutoff Protective valve, give automatically, the valve etc. of cutting off the water supply.Wherein, the automatic shutoff Protective valve is mainly used on the pipeline of the network of rivers, the buoyancy acting in conjunction of hydraulic pressure and buoyancy valve plate through two chambeies about control valve; Close the buoyancy valve plate by current, control valve and buoyancy valve plate are installed in the valve chamber, and its volume is bigger; When the needs water, during artificial opening controlling valve door, buoyancy is limited by real-time hydraulic pressure; Guarantee buoyancy valve plate both sides hydraulic balance, its Mechanical Reliability is not good, is not suitable for single family and uses.Automatically give, the valve of cutting off the water supply is mainly used in the just lavatory of public place, relies on the turnover of valve body to the perception control water of hydraulic pressure, its volume is big, requirement of mechanical strength is high.

Summary of the invention

The object of the invention provide a kind of simple in structure, volume is little, the easy to use and reliable automatic shutoff valve of cutting off the water supply.

The technological scheme that the present invention adopts is: comprise being arranged in pipeline and the axle center cylindrical spool vertical with the pipeline axle center; Cylindrical spool radially have a water port; The upper end intermediate vertical of cylindrical spool connects stretches out the outer handle of pipeline, is equipped with stuffing box bearing between the upper and lower end of cylindrical spool and the pipeline; Have the gap between the upper-end surface of cylindrical spool and the inner-walls of duct, gap location is provided with valve body, is connected the spring control gear between valve body and the handle; The spring control gear is made up of 2 second springs and 4 pull bars; 2 second springs are symmetrically arranged with respect to handle, and the two ends of each second spring connect a pull bar respectively, wherein; 2 the first all affixed valve inner side surfaces of pull bar, 2 the second all affixed handles of pull bar; Position at the water export of pipeline is provided with the current inductive probe, the time-controller that current inductive probe connecting tube is outside, and time-controller connects motor; Motor is fixedly connected gear; Bolt has an end of finer wire on the gear, and the other end of finer wire connects latch, and latch is arranged in the groove on the handle side wall; Latch also connects first spring, one end, and the other end of first spring is fixedly arranged on the pipeline outer wall.

The invention has the beneficial effects as follows: after water tap flows through certain hour, forgetting that when closing water tap, the present invention understands automatic shutoff, avoids the waste of water resources, operation is simple and feasible, is a kind of valve that not only had been fit to family but also had been fit to the advantages of small volume type of public place.

Among the figure: 1-pipeline, 2-current inductive probe, 3-time-controller, 4-motor, 5-gear; The 6-finer wire, 7-latch, 8-first spring, 9-handle; The 10-cylindrical spool, 11-spring control gear, 12-second spring, 13-1-first pull bar; 13-2-first pull bar, 14-valve body, 15-water port, 16-stuffing box bearing.

Embodiment

Shown in Fig. 1-2, the present invention includes cylindrical spool 10, cylindrical spool 10 is arranged in pipeline 1, and the axle center of cylindrical spool 10 is vertical with the axle center of pipeline 1, cylindrical spool 10 radially open a water port 15, promptly water port 15 axially and pipeline 1 axial consistent.All connect between the upper and lower end of cylindrical spool 10 and the pipeline 1, as rotational support, cylindrical spool 10 is rotated easily with stuffing box bearing 16 with stuffing box bearing 16.The upper end intermediate vertical of cylindrical spool 10 connects handle 9, and handle 9 stretches out outside the pipeline 1, has the gap between the upper-end surface of cylindrical spool 10 and pipeline 1 inwall, at gap location valve body 14 is installed.As shown in figures 1 and 3; Between valve body 14 and handle 9, be connected spring control gear 11, spring control gear 11 is made up of 2 second springs 12 and 4 pull bars, and 2 second springs 12 are symmetrically arranged with respect to handle 9; The two ends of each second spring 12 connect a pull bar respectively; Wherein, 2 first pull bar 13-1 of 2 second springs 12 all are fixedly welded on valve body 14 inner side surfaces, and 2 second pull bar 13-2 all are fixedly welded on the handle 9.

Position at the water export of pipeline 1 is provided with current inductive probe 2, with the induction current.At pipeline 1 outer installment time-controller 3, motor 4, gear 5, finer wire 6; 2 connect hours of current inductive probe controller 3, time-controller 3 connects motor 4, and motor 4 is fixedly connected gear 5; Time-controller 3 is given motor 4 with electrical signal transfer, and motor 4 driven gears 5 rotate.Bolt has an end of finer wire 6 on gear 5, and the other end of finer wire 6 connects latch 7, and latch 7 is arranged in the groove on handle 9 sidewalls, and latch 7 also connects first spring, 8 one ends simultaneously, and the other end of first spring 8 can be fixed on pipeline 1 outer wall.

Working procedure of the present invention is: behind user installation valve of the present invention, during water, earlier handle 9 is rotated for the first time, latch 7 gets in the groove on the handle 9 and blocks handle 9 under the tension force effect of first spring 8.When extraneous masterpiece was used in handle 9, interlock cylindrical spool 10 deflected, and makes second spring, 12 stressed generation extensional motions, the power that the while storage compartment resets.When water 15 when flowing out, makes second spring 12 be in extended state from the water port.Current inductive probe 2 passes to time-controller 3 to the signal of water flows, and time-controller 3 begins to calculate water and continues time of flowing, after water continues to flow a period of time (such as one hour; This time user can be set by time-controller 3), time-controller 3 sends electrical signal and gives motor 4, and motor 4 starts; Driven gear 5 rotates, and drives finer wire 6 and shrinks, and opens latch 7; Latch 7 pushes first spring 8 when leaving the groove on the handle 9, make handle 9 lose constraint, and second spring 12 in the spring control gear 11 is resetted by extended state; Driving cylindrical spool 10 simultaneously rotates with handle 9; Make water port 15 direction of water flows dorsad, thereby cut off current, reduced the user because of forgetting the waste of closing the water resources that water tap causes.After the user used a period of time, this moment is time of setting of no show time-controller 3 (time-controller 3 has time auto zero program) also, and valve just can not closed automatically, and whole timing system recovers ortho states again, saves up strength and prepare startup next time.
