Abstract

The utility model discloses a timing closed leakage-less water-saving valve which comprises an elementary valve, a signal valve and a controller. The valve cavity of the elementary valve communicates with the effluent passage of the signal valve, and the control signal of water pressure is provided to the controller by the signal valve. The utility model has the function of timing closure besides used as a normal valve and brings convenience to users. The utility model has good sealing performance of preventing leakage, because the center line of the elementary valve is departed a certain distance from the center line of an axle hole, the center line of the elementary valve chamfers the hemisphere gate valve, the heart of the elementary valve is different from the heart of the axle hole, and no water self-closed is realized; when the utility model is used the damage caused by coming water after cutting off the water supply when nobody is on the scene is avoided, and the water is saved.

Description

Timed leakage-less water-saving valve

The utility model relates to a kind of one-way cock in the common mechanical engineering.

Present widely used ball valve, gate valve, stop valve etc., the problem that exists is jointly, and Control Shaft and closure are in same axis centre, and confining pressure is broken through the part gap that is exposed in the closure, causes the back new race of sealing, emits, sews drain-source.In order to address this problem, some products build seal ring as possible in the axial line control hole, but cause the increase of close wiping coefficient therefrom, make the moment of torsion of Joystick increase, and operation is effort especially.The function that existing valve does not generally have timing to close is unsuitable for certain user's needs.In addition, people forget because of various reasons after opening tap and close, so that when usually coming water again after cutting off the water, cause a large amount of losses and the waste of water, even overflow and cause " floods ".

The utility model with said structure should be connected the tunnel ends that becomes a mandarin of sentinel valve in use with the water source, obtain water from the valve pocket outlet of basic valve.Working condition when selector knob is placed two different operating gears is as follows:

(1) select knob to place " generally " gear.Positioning ball on the intermediate clapboard enters positioning hole corresponding on the selector chassis at this moment, the chassis is located, angle of the right deviation of lever of while selector, its rear end contacts with right control button lever rear end, the groove of its front end entering signal valve interlinking lever end and joining with the sentinel valve connecting rod, this moment, selector lever left two ends all were in neutral state.Be in can being divided into of " generally " when shelves: 1. short time water with aqueous condition.With rotatable handle rotation and make angle of swing less than 90 °, handle rotates by the hemisphere family of power and influence that cuts sth. askew that major axis drives basic valve, current back down its piston from the circulation road of going into of sentinel valve, through piston cavity with go out the valve pocket that circulation road flows into basic valve, flow out from the valve pocket outlet again.Meanwhile, major axis drives spur wheel and rotates, and makes left thread rolling bar pulling extension spring move forward and make right thread rolling bar compression press spring to move backward.Because the angle of swing of rotatable handle is less than 90 °, the displacement distance of left and right thread rolling bar is limited, so their tight locking button can not be respectively with left and right control button lever on control buckle and be interlocked, as long as therefore revolving the hand of handle in a single day unclamps, under the elastic force effect of extension spring and stage clip, left and right thread rolling bar and spur wheel all reset, and drive major axis and reset, the hemisphere family of power and influence that cuts sth. askew closes at once, and current stop.2. long period water.As long as the angle of swing of rotatable handle is greater than 90 °, the tight locking button on the then left and right thread rolling bar just can be buckled with the control on the left and right control button lever and be interlocked.Even open openhanded this moment, extension spring and stage clip can not make major axis reset, so current can continue.As not needed water, as long as press the X button at controller top with hand, left side control button lever front end is descended, rise by connecting the right control button of lever drives lever front end, so the tight locking button that the control of left and right control button lever is buckled simultaneously respectively with left and right thread rolling bar is separated, so under the effect of extension spring and stage clip, major axis resets, the hemisphere family of power and influence that cuts sth. askew closes, and current stop.3. the water source is anhydrous.There is not hydrodynamic pressure this moment, the piston of sentinel valve descends, the sentinel valve push rod falls, sentinel valve main lever rear end in the controller descends and the front end rising, the sentinel valve connecting rod is risen, so drive the right lever rear end decline of selector and press right control button lever, make right control button lever front end rise, descend by connecting lever drives left side control button lever front end simultaneously, this just presses the effect of X button as aforementioned hand, major axis is resetted, and the hemisphere family of power and influence that cuts sth. askew closes, thereby realizes anhydrous self-closing.

(2) selector knob places " timing " gear.Positioning ball on the intermediate clapboard changes positioning hole corresponding on the selector chassis at this moment, the chassis is located, angle of selector lever left deflection simultaneously, its front end contacts with left side control button lever front end, its rear end enters timer disk cam below and contacts with the bottom surface, and the right lever of selector this moment two ends all are in neutral state.Be in can being divided into of " timing " when shelves: 1. timing water with aqueous condition.The rotary timer knob, clockwork spring tightens, timer is in timing position, with rotatable handle rotation and make angle of swing greater than 90 °, an aforementioned left side, other and the left side of right control deduction of points, right tight locking button is interlocked, the water that flows rises by piston rod driving signal valve push rod, back down the mainspring barrel ratchet that external ratchet on the timer valve rod makes it release timer, mechanical timer runs well, the also run-in synchronism of timer disk cam that links to each other with the main rotating shaft of timer, when arriving preset time, the lowest part of timer disk cam presses down the selector lever left and makes on its rear end and rise, and descends so drive left side control button lever rear end rising front end, rise by connecting the right control button of lever drives lever front end simultaneously, this just presses X button as aforementioned hand effect is closed the hemisphere family of power and influence that cuts sth. askew, and realizes the timing water.2. timer knob is not-time.Because no timing, the lowest part of timer disk cam presses the selector lever left all the time to be made on its rear end and rises, and as described in 1., the hemisphere family of power and influence that cuts sth. askew is in closed condition, anhydrous supply.3. timer knob timing but the water source is anhydrous.Because it is anhydrous, the sentinel valve push rod descends, external ratchet on the timer valve rod fastens the mainspring barrel ratchet of timer, mechanical timer can not timing, and the timer disk cam does not move, in case come water, the sentinel valve push rod rises, external ratchet on the timer valve rod upwards breaks away from the mainspring barrel ratchet, the normal timing of timer, and its working procedure is identical with aforementioned timing water.

Therefore the utility model is because basic valve has the hemisphere of the cutting sth. askew family of power and influence and special constructions such as major axis and minor axis, so sealability is better and have no leakage than general valve.The application of clocking capability greatly facilitates the user.Anhydrous self-closing function, making can a large amount of using water wisely and prevent to cause " floods " to endanger.
