Abstract
The utility model relates to an automatic closing water tap which can be automatically closed after the automatic closing water tap is opened. The utility model is characterized in that a valve seat is arranged on the upper part, and a valve disk is arranged on the lower part. The lower part of a water tap is provided with a technological hole, and is provided with a device of a lifting mechanism. The water inlet point of the water tap is provided with a device of an adjusting mechanism. The device of the lifting mechanism is composed of a spring 10, a lifting rod 13, a casing 18 of the lifting mechanism, etc. which realize the automatic closing of the water tap. The device of the adjusting mechanism is composed of a casing 26 of the adjusting mechanism, a tower-shaped sleeve 27, a spring 28, etc. which cause the water pressure at the inner pat of the water tap to be relatively stable.
Description
Automatically close water tap and be used for pipeline, the keying of container.
Traditional water tap is made up of housing, valve disc, valve seat etc., relies on valve disc to compress from the top down or throw off the valve seat realization to open and close.
The purpose of this utility model is to set up the lift device by changing the mutual alignment of valve disc, valve seat, controlling mechanism device, the automatic and manual-lock of realization water tap.
The purpose of this utility model is to realize like this, rubber ring 8 is equipped with in (referring to Figure of description 1) valve rod 2 lower ends, make it be adjacent to valve disc 9, valve rod 2 is packed into from the auxiliary hole of tap shell lower end, valve disc 9 is down, and valve seat 7 is last, and rubber ring 6, pad 5 are packed in the hole on tap shell 4 tops, regulating wheel 3 usefulness are threaded in the upper end in this hole, the valve rod 2 upper ends handle 1 that is threaded.More than constitute tap shell assembly I.
Lifting lever 13, inner chamber pack into successively roundlet ball 17, spring 14, jackscrew 11, its outside is loaded onto spring 10, pad 15, rubber ring 16 successively, and the lifting lever 13 that installs is inserted in the inner chamber of lift housings 18.More than constitute lift assembly II.
Curved plate 20 usefulness nuts 21 are fixed on the right-hand member of screw rod 22, and it is packed into from water tap bottom auxiliary hole, load onto valve disc 23, controlling mechanism housing 26, spring 28, turriform cover 27, chamfered edge pad 25, nut 24 again on screw rod 22 successively.More than constitute controlling mechanism assembly III.
Assembly I realizes being connected by screw thread with assembly II.Assembly III is fixed on the water inlet place of assembly I by screw rod 22, curved plate 20, chamfered edge pad 25, nut 24.
Subelement structure and effect.
Valve rod 2 lower taper cylinders play the guiding role.Regulating wheel 3 is used for compressing or unclamps rubber ring 6, so that it keeps a suitable elasticity with valve rod 2.Pad 5 is set up for the friction of eliminating regulating wheel 3 and rubber ring 6.Chamfered edge pad 25, the both sides of pruning are in order to allow water pass through smoothly, and valve disc 23 effects are that it moves to the left side, closes the circular hole on controlling mechanism housing 26 the right when pipeline generation negative pressure.
The utility model also has the function of closing automatically except that manual-lock.
Accompanying drawing 1 is the water tap general assembly drawing, and it reflects the position and the annexation of each part; Accompanying drawing 2 is a curved plate 20; The shape of accompanying drawing 3 reflection apertures 19; Accompanying drawing 4 is a chamfered edge pad 25.
The working principle of tap shell assembly I and lift assembly II.
Accompanying drawing 1 is the water tap closed condition.When giving handle 1-downward pressure, valve rod 2 moves down, and valve disc 9 is thrown off valve seats 7, valve open.Valve rod 2 compressing lifting levers 13 descend, and the water in lift housing 18 inner chambers overcomes the expansion force of spring 14 by aperture 19, and jack-up roundlet ball 17 enters lifting lever 13 inner chambers, through aperture 12, flows out from tap outlet.Stop the pressure to handle, lifting lever 13 upwards rises under the effect of spring 10 at leisure, drives valve rod 2 throttle downs, has realized closing automatically of water tap.
Why can lifting lever 13 rise under the effect of spring 10 at leisure?
Because two aspects are arranged from resistance to spring 10, one: the negative pressure of lift housing 18 inner chambers, this resistance is bigger, two: handle 1, valve rod 2, lifting lever 13 from gravity, the frictional force of valve rod 2 and rubber ring 6, the frictional force of lifting lever 13 and rubber ring 16, this resistance is less, and the design expansion force of spring 10 can only overcome the latter, i.e. two resistance.Have only when water enters the inner chamber of lift housing 18, lifting lever just can rise.Water enters lifting lever 13 inner chambers from aperture 12, and slowly the inner chamber of inflow lift housing 18 from the slit that roundlet ball 17 and aperture 19 (referring to accompanying drawing 3, aperture 19 inwalls longitudinally process minor groove one) form has been filled up the vacuum of this inner chamber.
The working principle of controlling mechanism assembly III.
Water flows into the inner chamber of controlling mechanism housing 26 from chamfered edge pad 25 both sides, overlap 27 right-hand members through turriform, (turriform cover diameter of bore is greater than screw rod 22 external diameters, be the turriform cover can be on screw rod 22 move left and right) and the gap that forms of controlling mechanism housing 26 right-hand member circular holes, through valve disc 23 external diameters (23 can be on screw rod 22 move left and right, this moment, valve disc was displaced downwardly to water tap water inlet low order end at the pressure of current) and the gap of water tap water inlet right-hand member internal diameter formation, through curved plate 20 and water tap lower inner wall, the slit of (because curved plate 20R and water tap bottom internal diameter R are inconsistent) the two formation enters water tap inside again.
When water inlet hydraulic pressure is big, water overlaps 27 left sides to turriform and produces a pressure, when this pressure overcomes the expansion force of spring 28, turriform cover 27 can move right, thereby the gap that turriform cover 27 and controlling mechanism housing 26 the right circular holes are formed dwindles, and water flow can reduce, otherwise, spring 28 moves to left the turriform cover, and the gap increases water flow and increases.Assembly III has guaranteed that head dragon internal pressure is relatively stable.Stablizing of hydraulic pressure, to make the water tap automechanism be opened into the cycle time of closing more stable at every turn.
With portable handle 1, under the acting in conjunction of hydraulic pressure and spring 10, realize the manual-lock of water tap
