Operation instruction
During original state, water tap is in closed state, and the water outlet 45 of valve block coincides with the real district 53 of closing of lower valve on this moment, and the intake pipe of current by the housing rear end connects screw socket and enter housing, is hindered below in lower valve by the valve block of two closures.This moment, the driving lever 43 of spool nestled up the side that driving lever stops platform 50.Regulating handle 19 and the whole loam cake of water tap loam cake remain static.
Rotate regulating handle 19, handle band movable valve plug 24 rotates.Because valve spool driving lever is fixed in the driving lever groove 35 of valve block, so driven again the rotation of upper valve block. and lower valve is by fixedly the remaining static of restraining groove 49 and restraining groove 36, this moment, two valve blocks misplaced.Water outlet 45 beginnings of upper valve block and the water intake 46 of lower valve overlap gradually, bear the space, and the current that amass this moment under lower valve flow through valve block by the space, flow through water control valve water outlet 5, flow through water channel control block water outlet 25, flow out tap water outlet nozzle 47, used by the user.
Be rotated further regulating handle 19, two valve block spaces and continue to widen, to such an extent as to be equal to the size of valve block water outlet 45 fully, this moment the water tap water-outlet quantity that reaches capacity, waterflow stabilization flows out.
Be rotated further regulating handle, driving lever 54 was owing to be provided with the groove 51 that stops platform at this moment, so can stop platform 50 by driving lever, this moment, regulating handle rotated 180 degree.
Be rotated further regulating handle, this moment, driving lever 43 did not have to stop the groove of platform, ran into driving lever and stopped that platform stops later that rotation is reached home.Because the inner 56 of coil spring is fixed in the inner mounting groove 33 of spool, the outer end that outer end 55 is fixed on the coil spring box articulates in the groove 9 again.And coil spring box 10 is fixed on the secured adjusted seat 20 by connecting pawl 8, the secured adjusted seat is fixed on the water channel control block by teeth groove is meshing by spring 21 tensionings, because the water channel control block is welded on the housing, so be static, so the outer end 55 of coil spring also is fixed static.When rotating regulating handle, coil spring the inner 56 and then is rotated, and upper elasticity is held in coil spring generation deformation.Unclamp after the regulating handle, coil spring is replied deformation, discharges elastic force, and elastic force overcomes the frictional force between valve block, and the band movable valve plug is returned to original state, and two valve blocks are again closed, and current are blocked under the lower valve, and water tap is finished one-off.
The elastic force of coil spring increases along with the increase of deformation quantity.Along with the angle of rotating regulating handle increases gradually, the elastic force of accumulating on the coil spring also can be increasing, and is level and smooth for the rotation that realizes handle, is provided with half hollow slots 34 below upper valve block.Along with the rotation angle of handle increases gradually, elastic force on the coil spring increases gradually, under the effect of half hollow slots, the area of contact of two valve blocks increases gradually, frictional force between two valve blocks increases gradually, coil spring will recover the valve block frictional force that deformation will overcome and increase gradually, realizes coil spring elastic force and will overcome that the same of frictional force increases with subtracting between valve block with this, realizes the automatic smoothing revolution of regulating handle under the coil spring effect with this.
Coil spring can elasticity occur after using a period of time tired out, elasticity changes, and two valve blocks in the spool are because the variety of issue in using, valve sheet from being worn for example, long-pending upper incrustation scale, or water temperature changes expanding with heat and contract with cold of causing the frictional force between two valve blocks is changed, and then causes the big or small unbalance of frictional force between coil spring elastic force and valve block, brings problem to use.It is normal that the size that just needs to regulate coil spring power this moment realizes using.Secured adjusted seat 20 also has the effect of regulating the coil spring degree of tightness except the effect with fixing coil spring box.Hold secured adjusted seat 20 this moment, up mention gently (spacing of the adjustable lever 17 in secured adjusted seat and the loam cake is greater than the height of teeth groove 38), overcome the tension force of spring, the teeth groove that its disengaging is used for fixing, break away from after the teeth groove, the secured adjusted seat of this moment can left rotation and right rotation.The rotation of secured adjusted seat 20 drives the rotation that the coil spring box of inserting in the inner is fixedly connected with pawl 8, and then drives the rotation of coil spring box.The rotation of coil spring box drives again the rotation of coil spring outer end 55.Coil spring the inner 56 is connected on the spool, and be in the fixed static state this moment, so the rotation of coil spring outer end can realize the degree of tightness of coil spring, and then the state of adjusting coil spring.It is tighter that coil spring is received, and after the inner turned an angle, the power of putting aside was just larger, and vice versa.
After coil spring is transferred to suitable degree, unclamp the secured adjusted seat, under the effect of spring 21 tension forces, the secured adjusted seat is retightened on housing teeth groove 38, gets back to the fixed static state.The adjusting of coil spring is finished.
This is a delay water faucet, and water discharging time can increase along with the angle of swing of regulating handle and increase.And can satisfy especially the multiple user demand of user greater than the adjusting angle of 180 degree, and more brought convenience to use when realizing water saving, be specially adapted to the public arena.
In order to satisfy more kinds of demands, this water tap also has the long-time water supply function of ordinary faucet.Adjustable lever 17 in the lid of water tap loam cake 11 is provided with eccentric wheel 18. capping direction on being parallel to and rotates regulating handle to several angle, and after realizing discharging water, perpendicular to capping direction twisting regulating handle 19, the band movable eccentric wheel rotates again.After eccentric wheel turns to several angle, touch coil spring box cover plate 13, and rub with it, after frictional force acquires a certain degree, decontrol regulating handle, this moment, frictional force was greater than the turning power on the spool, turning power is yielded to frictional force, and upper box face is fixed, and loam cake is static, the spool that is fixedly connected with loam cake is static, realizes discharging water for a long time of this kind of product with this.
