Description

Delay-action automatic closing tap

The utility model relates to a kind of water-saving valve, and particularly a kind of piston type automatic delay function water nozzle can be widely used in the water supply pipe of family, restaurant, hotel and other public place.

In the water supply pipe of family, restaurant, hotel and other public place, the most frequently used control water valve is the mechanical type water nozzle.It adopts the separated type flap of screw rod control to realize the purpose that water nozzle opens and closes.In long-term using process, the sealing gasket on the flap is easy to wear, aging, and water leakage phenomenon occurs repeatedly.During normal water supply, not turn screw rod then can't be closed automatically.It is unexpected that pipeline stop to supply water and forget and close water nozzle when water in addition, tends to cause " metalling run out " disaster.For addressing the above problem, various automatically controlled automatic turn-off water taps, water-stopping self-closing Safety water-cock produce in succession.Common have automatically controlled water nozzles such as infrared rays, phototube, float-ball type, a bolt-type Safety water-cock.But automatically controlled water nozzle be difficult for is promoted by the restriction of service condition, and Safety water-cock opens and closes trouble of operation, and can not close voluntarily during normal water supply, also influences its usability.

The purpose of this utility model provides a kind of piston type delay-self-closing water nozzle, and it is rapid that its regulates water flow, at normal water supply or the Shi Junneng that cuts off the water suddenly close automatically, effectively prevent percolating water, stop perennial draingage, water-saving result is remarkable.

The purpose of this utility model is achieved in that this device comprises that valve body, valve gap and assembling wherein utilize the axis body of handle control, the ratchet-type transmission body that is fixed with spiral spring on the axostylus axostyle of its central axis and drives by the damping transmission device, be processed with " L " shape slotted eye of axial symmetric arrangement on the axle sleeve of axis body, the projection that is assembled in the piston upper end in the axle sleeve passes " L " shape slotted eye, is inserted into valve body and connects in the spiral chute of neck inner hole wall.

Because the utility model adopts the piston that is assembled in the axis body axle sleeve to replace the separated type flap of traditional water nozzle, and spiral spring and ratchet-type transmission body that the axis body utilization installs on it realize moving axially, reach the purpose of closing automatically, so overcome " metalling run out ", the defective of leaking that existing water nozzle exists effectively, fundamentally solved and forgotten to close perennial draingage or " metalling run out " problem that water nozzle causes, so water-saving result is remarkable.

The utility model is described in further detail below in conjunction with accompanying drawing.

Describe concrete structure of the present utility model in detail according to Fig. 1-6.This device comprises valve body 4, valve gap 9 and is assembled in wherein axis body 5, damping transmission device, ratchet-type transmission body 15, is assembled in the parts such as piston 2 in axis body 5 axle sleeves.Its central axis 5 tops are solid shaft, and the bottom is shouldered hollow shaft sleeve, and axostylus axostyle, axle sleeve are processed into one.The ratchet-type rotor 15 that is fixed with spiral spring 18 on the axostylus axostyle and drives by the damping transmission device.Be processed with " L " shape slotted eye 3 of axial symmetric arrangement on the axle sleeve, this slotted eye 3 has two at least.Piston 2 is assembled in the axle sleeve of axis body 5, and sealing gasket 1 can be installed in its end, so that be pressed in the water outlet upper end of water nozzle seat 23, also can not establish sealing gasket, makes the integral type elastic piston, is pressed in the water outlet inner hole wall end of water nozzle seat 23, reaches the purpose of closing water nozzle.Piston 2 upper ends and axle sleeve " L " shape slotted eye 3 opposite positions are processed with projection 17, and projection 17 passes " L " shape slotted eye 3, and can move and rotate with axle sleeve along slotted eye is upper and lower.Projection 17 on the piston 2 passes axle sleeve " L " shape slotted eye 3, its styletable is inserted in each spiral chute 16 of connection neck inner hole wall of valve body 4, utilize handle 10 control axis bodies 5 to rotate, move along the spiral chute 16 of valve body 4 inner hole walls projection 17 ends when axle sleeve rotates on the drive piston 2, piston 2 can be rotated around its axis, can utilize the water outlet of piston 2 control water nozzle seats 23 to open, close along its axially upper and lower moving again, reach the purpose of adjusting current.Axis body 5 utilizes leakproof seal pad 6 and gland 7 axially locating in valve body 4 counterbores.The ratchet-type rotor 15 that is assembled on axis body 5 axostylus axostyles is made of ratchet, resilient latch 21, stop-motion body 19.Its ratchet comprises the wheel disc 20 that has locking groove and installs all-in-one-piece external toothing 22 with it.Movable pallet 21 utilizes cluster spring to be contained in the radial hole of stop-motion body 19, and is close in the locking groove of reel 20 by the pressure of spring, and stop-motion body 19 is undertaken on wheel disc 20, does not rotate each other.The damping transmission device that drives ratchet-type rotor 15 comprise the gear train 11 that is assembled on the spiral spring frame 8, turbine 12, scroll bar frame 14 and on scroll bar 13(Fig. 1 shown in structure be sectional stretch-out view along its each axial direction).The external toothing 22 of rotor 15 is meshed with gear train 11.Have damping fan blade 25 on the scroll bar 13.

During use, this device is assembled on the water nozzle seat 23 that has water intake and water outlet by sealing gasket 24, is installed on the water supply pipe and gets final product.Also can lay down, directly this device is installed in the water nozzle seat having assemblies such as the gland of common water nozzle and handle, screw rod, flap now.Rotatable handle 10 drives axis body 5 and rotates, and spiral spring 18 is stressed, and axis body 5 is produced revolution torsion, and meanwhile, the stop-motion body 19 that is packed on axis body 5 axostylus axostyles drives the locking groove that spring catcher 21 slips over wheel disc 20, and stop-motion body 19 is rotated relative to wheel disc 20; Be assembled in the piston 2 in axis body 5 axle sleeves, under the axle sleeve that rotates drives, make the projection 17 on the piston 2 move and rise along axis body 5 axis along the spiral chute 16 of valve body 4, the sealing gasket 1 on the piston 2 leaves the water outlet of water nozzle seat 23, then opens water nozzle.If water not, then rotatable handle 10 drives axis bodies 5 backward rotation, and the also reversing motion of then above-mentioned parts reaches piston 2 and descends fast, closes the purpose of water nozzle.If rotatable handle 10 not during water not, then axis body 5 counter-rotating voluntarily under the revolution twisting force of spiral spring 18, stop-motion body 19 and wheel disc 20 on this moment axis body 5 axostylus axostyles, under the effect of resilient latch 21, be undertaken on together, drive external toothing 22 rotations, thereby make the component movement of the damping transmission device that is meshed with external toothing 22, control spiral spring 18 revolution torsion discharge lentamente, drive axis body 5 rotations, piston 2 is descended gradually, reach the purpose of automatic delay function.
