Description

Multifunction automatic water tap

The utility model relates to a kind ofly can make the multi-functional Automatic water tap that common water nozzle can be used for controlling automatically the container water storage capacity again.

A kind of multi-functional full-automatic water tap is disclosed at CN2108823U, it is by valve body, the valve seal lid, on the basis of the ordinary tap water tap that spool and handle are formed, be provided with by float, connecting rod, the mechanism that the control that lever is formed opens and closes, for realizing control, also taked the piston rod type spool on the structure, the outer end of spool is that control end is a cylindrical shape boss, the side face of boss is carved with " " shape locating slot, outer cover of fixedlying connected of boss outside suit with sealing cover, the barrel of outer cover is provided with the driving lever that can embed locating slot, have a vertical groove on the outer cover barrel, lever is installed on the outer cover by bearing pin, and an end of lever penetrates in the outer cover to the boss below from groove.Its deficiency is, complex structure not only, and difficulty of processing is big, and the water tap closing function is unreliable.Here be that contact is connected between the boss of lever end and spool upper end, so lever is easy to by boss spool be levered up, thereby with the water tap breakdown; But leverage makes it to close the active force of water tap downwards in spool, be rubbing action generation,, very easily cause poorly sealed owing to friction force will reduce along with the abrasion of working surface and the light that rubs by lever end and spool, produce and leak, influence its working life.

It is a kind of simple in structure that the purpose of this utility model is to provide, reliable operation and multi-functional Automatic water tap easy to install.

Technical solution of the present utility model is on the basis of push type water tap, removes and pushes handle, replaces leverage and forms.Comprise that promptly valve body, valve gap, valve rod, the flap that is fixed on valve rod one end, active force make the multi-functional Automatic water tap of the spring of flap close port in valve rod, it is characterized in that being provided with the leverage that is used to handle valve rod at the other end of valve rod, one end of lever is connected with valve gap by free connecting rod, its the other end is connected with buoyancy by lifting rope, and the drag effect point between the lever two ends is connected with valve rod by bearing pin.Buoyancy in the utility model is that unit weight is a bit larger tham the heavy thing piece of the water capacity, during use, buoyancy is placed such as water vat in the resevoir.When water in the cylinder was full, buoyancy submerged and is subjected to the buoyancy maximum, and acted on the power minimum of lever by lifting rope, and this moment, valve rod upwards was displaced to upper limit position under the effect of spring and water pressure, and water nozzle is closed; When the water in the water vat reduced, the buoyancy that buoyancy is subjected to reduced, and acted on the power increasing of lever by lifting rope, when power greatly to can overcome spring and water pressure the time, promptly promote valve rod to bottom offset, water nozzle is by breakdown, water injects in the cylinder, so realizes control automatically.

Advantage of the present utility model is, and is not only simple in structure, has all advantages of push type water conserving tap, and can implement the automatic control of container water storage capacity reliably.Act on the spring that valve rod makes flap sealing valve port owing to be provided with, under the effect of spring and tap water pressure, flap can be implemented close port reliably, leakage phenomenon can not take place, therefore, as long as adjust the size of buoyancy and the ratio of lever moving arm and resistance arm, just can implement automatic control reliably.Promptly become the common push type water nozzle of using lever if take off buoyancy, install simple, easy to use, reliable.

Accompanying drawing is a structural representation of the present utility model.

Below in conjunction with accompanying drawing the utility model is described in detail.The utility model is actually combining of push type water tap and leverage.As shown in FIG., 1 be installed with water inlet one side that flap 15, flap are located at valve port 20 for valve rod, the end of valve rod in valve body for valve gap, 4 for valve body, 3.12 for acting on the spring that valve rod makes flap sealing valve port, and it is sleeved on the valve rod, and its upper end is fixed on the valve rod by bayonet lock, and the lower end is stuck on the valve body.18 for being used for the lower end cap of sealed valve stem, flap mounting hole among the figure, and 17 is sealing gasket.Above-described structure and push type water tap of the prior art are identical.In order to realize the automatic control of water nozzle, leverage has been installed in the outer end of valve rod 4.As shown in FIG., the fulcrum 9 of lever 5 is located at the one end and flexibly connects by free connecting rod 10 and valve gap 3; The power point 24 of lever 5 is located at its other end and is connected with buoyancy 21 by nylon lifting rope 23; The resistance point 8 of lever 5 is connected between fulcrum 9 and power point 24 and by the outer end of bearing pin with valve rod 4.Buoyancy 21 is thing pieces that a unit weight is a bit larger tham water in the utility model, and it is a plastic hollow obturator of usefulness in the present embodiment, places water not float on the water surface.Therefore, buoyancy is hung in when placing in the water container appropriate location on the lever, it is subjected to the power that buoyancy of water or buoyancy act on lever, will be submerged degree with buoyancy and change.When water level rises to buoyancy and is immersed in the water fully, act on the power minimum of lever, when drawdown surfaces the most for a long time to buoyancy, act on the power maximum of lever.Therefore, selected under the situation of buoyancy,, can implement the automatic control of water storage position as long as adjust the size of lever moving arm and resistance arm.In the present embodiment, in order to improve the sealability and the operation resistance that reduces valve rod between valve rod 4 and the valve body 1, adopted the diaphragm type water seal, promptly between valve rod 4 and valve body 1, the diaphragm type water seal is installed, the peripheral sealing and fixing of disc diaphragm type water seal is in valve body 1, and the center hole of water seal is sleeved in the circumferential groove on the valve rod 4.Present embodiment has been installed two water seals, and the periphery of last water seal 11 is fitted in the upper end of valve body 1 by valve gap 3, and its center borehole jack is contained on the valve rod and makes it to embed in the circumferential groove on the valve rod and forms sealing; The periphery of following water seal 14 is fixed on by water seal trim ring 13 on the inner convex platform of valve body 1, and interior formation of following circumferential groove that its center borehole jack is contained on the valve rod seals.Present embodiment also is fixedly mounted on permanent magnet 7 on the valve gap 3 by permanent magnet fitting seat 6, places the top of valve rod upper end, and makes valve rod when upper limit position, and its upper end contacts with permanent magnet 7.Permanent magnet participates in the automatic control of water nozzle to the suction-combining force of valve rod, can guarantee that a bigger control water level is poor, and improve the speed that water nozzle is opened or closed, and overcomes the simple the sort of asymptotic slow process that water nozzle is opened or closed during with spring.If the drag effect point 8 of lever 5 is made two section telescopic bars to one section between the power point 24, also can realize semiautomatic control.Power arm by flexible rod shortening lever makes buoyancy under the situation that surfaces fully, and can not open valve automatically when being in upper limit position, and artificially lever be pressed down when being in the breakdown position, be to rest on by the breakdown position.When water level rising buoyancy did not have the entry medium power to reduce, valve rod rose thereupon, and when rising to certain position, the magnetic force that is increased gradually sucts valve rod, thereby realized auto-closing, realized semiautomatic control.Permanent magnet also can magnetize drinking-water to a certain extent, useful people's health.2 for reinforcing nut among the figure, and 16,19 is entery and delivery port, and 22 is the buoyancy subframe, prevents that buoyancy from touching in resevoir.
