Description

Automatic cut-off water-saving valve

The utility model relates to a kind of water tap, especially for the running water tap that uses in the daily life with delay-self-closing function.

In the prior art, the valve with automatic closing function has a lot, and the concrete function structure has varied, and self-closing valve under water-supply off is arranged, and regularly self closing stop valve is also arranged, and this has more disclosing in Chinese patent literature, and its oneself pluses and minuses are respectively arranged.As the timing automatic closing valve of CN92216164, CN92225084 patent disclosure, it is to be provided with a timing timer, drives valve core rod by driving mechanism and realizes regularly from closing the border valve.These two kinds of valves are structural and use the spool reliable in action influenced greatly by pressure medium from it, can not fully be adapted to particularly tap water of liquid.' the semi-automatic quantitative water supply valve ' of CN92224729 patent disclosure, it is made up of metering mechanism, drive link, valve body etc.Metering mechanism is made of the impeller drive set of gears driving mechanism of installing in conduit that rotates by the current red switch.After this valve is pressed lower valve rod with hand, valve rod is stopped by the termination bayonet fittings of drive link, can not self-return, and valve is in opened condition, when water output reaches definite value, when being the action of gear drive drive drive link, make drive link break away from valve rod, valve rod resets and makes valve closing, see that from textural this valve manufacture difficulty is big, the transmission matching relationship is many, needs regularly, opens twice operation of valve in the operation, and it is also imperfect.

But the purpose of this utility model provides the water-saving tap of an automatic delay function, especially for the self-closing water-saving tap of tap water that uses as family, toilet etc. in the daily life, use as water-saving tap rather than metering mechanism, metering valve, the water tap that the utility model can be closed automatically, be not that its timing of requirement is very accurate, or it is quantitatively very accurate, but for economize on water, health, with satisfy usage requirement, easy to use, simple in structure, cost is low, easily manufactured, adaptive capacity is by force its target of being pursued.The utility model also is to improve at the deficiencies in the prior art.

The utility model includes valve body, spool device, and its major technique is characterised in that: valve rod can slide up and down mobile being installed in the valve body by the thrust spring effect, cooperates with inner chamber valve port in the valve body; Be provided with on the top of this valve body the device that a control valve is opened delay-self-closing is installed, the spring that this self-closing device includes a housing that partly is fixedly connected with valve body, be installed in a spindle rod in this housing, resets spindle rod to rotate, one are used for time-delay and time-controlled gearing; The upper end of said spindle rod is stretched out the housing upper end cap movingly, be provided with an axial cam disk in the connection of the lower end of spindle rod, this cam disk touches with aforementioned said valve rod upper end and cooperates, and touches during by turn and controls valve rod and do knee-action at spindle rod, and the valve port of valve is opened or closed; Said be used to delay time and gearing regularly be by with the spindle rod transmission joint step by step the plurality of gears of transmission constitute.This device, when rotating spindle rod with hand, the cam disk effect of spindle rod lower end presses the valve rod of valve, make valve open, the rotation of spindle rod simultaneously makes the aforementioned said spindle rod stressed resiliently deformable of main spring that resets, after stopping to the rotation of spindle rod forward turn-knob, spindle rod begins oppositely to circle round under the effect of its main spring that resets, when spindle rod turns round, utilize the transmission of aforementioned said gearing, the reset speed of circling round that spindle rod is slowed down and controlled to the rotation friction, reach the valve delay-self-closing is controlled.

Accompanying drawing is the utility model example structure schematic representation.

Embodiment describes the utility model below in conjunction with accompanying drawing:

The utility model includes valve body F and delay-self-closing device K two large divisions to be formed, and valve body F partly includes the sealing gasket 5,6,7 that valve body 1, spool 2, valve rod 3, valve rod 3 reset on the thrust spring 4 and the face that respectively is sealed and matched and constitutes.The installation that is fixedly connected of spool 2 and valve body 1 usefulness screw-thread fit, offer valve hole 9,9 ' in the lower end of spool 2, valve rod 3 movably places up and down and is installed on the spool 2, and its lower end cooperates with the valve hole 9 of spool 2, and the Returnning spring 4 of valve rod 3 is installed in the top of valve rod 3.Mounted valve automatic delay function device K is set in the upper end portion of valve body F, it includes housing 20, be installed in spindle rod 21, spindle rods 21 revolution Returnning springs 22 in the housing 20, be used for time-delay and time-controlled one group of gearing 30, the upper end of the lower end of housing 20 and spool 2 or valve body 1 is fixedly connected with screw-thread fit, spindle rod 21 Returnning springs 22 are disc springs of a clockwork spring type, stretch out outside housing 20 upper end caps 20 ' upper end of spindle rod 21, and a manual knob 23 is installed.Its lower end surface that is fixedly connected in the lower end of spindle rod 21 is the dish that presses that the plane of inclination is arranged, be axial cam dish 24, this cam disk 24 touches with the upper end of valve rod 3 in extending into housing 20 and cooperates, when spindle rod 21 during by turn, drive and 3 actions of control valve rod, finish the water valve work that opens and closes.Shown in the accompanying drawing, cam disk 24 and 3 of valve rods be provided with one with the drive link 25 of the hinged installation of housing 20 parts, cam disk 24 is by these drive link 25 recharge valve bars 3, drive link 25 also rises spindle rod 21 return positioning actions simultaneously.Be used to delay time and gearing 30 regularly, be by being installed in master gear 26 on the spindle rod 21 and the transmission of some preferably speed increasing ratios, do not require that the gear 31-37 that targeted loads promptly dallies constitutes, this gearing is installed on the

installation clamping plate

41,42 that fixedly connect with housing 20.

The utility model is rational in infrastructure, and manufacturing is simple and convenient, and adaptive capacity is strong, but be not subjected to the manifold pressure size to influence all proper functioning, easy and simple to handle, be particularly suitable for being applied to occasions such as family, toilet and use, for the user provides convenience, and health, water saving.
