Wherein, 1, valve body; 11, valve seat; 12, valve gap; 2, spool; 21, closeouts; 22, valve rod; 3, rubber membrane; 4, Returnning spring; 5, top pressure lever; 6, cam; 7, wind-up timer.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further, understands the utility model technical thought required for protection so that clearer.
As shown in Figure 1, 2, be Timed valve of the present utility model, comprise valve body 1, valve body 1 can be arranged on up or down in and for control this Timed valve opening and closing spool 2, for controlling the control gear that spool 2 moves up and down; Described control gear comprises and is arranged on Returnning spring 4 between valve body 1 and spool 2, can presses lever 5, wind-up timer 7 around the top of fulcrum; The output revolving shaft of described wind-up timer 7 is connected with cam 6, wherein one end of described top pressure lever 5 coordinates with cam 6 activity, thus make top press lever 5 and the different labyrinths location contacts of cam 6 by the rotation of cam 6 and around fulcrum, the other end and spool 2 upper end thereof.Concrete, the two ends of described top pressure lever 5 are placed in the both sides of fulcrum.
In use, output revolving shaft band moving cam 6 by wind-up timer 7 rotates, and press lever 5 around fulcrum by utilizing cam 6 and top to press the mating reaction of lever 5 to impel to push up, thus be with movable valve plug 2 to move by top pressure lever 5, and, by the elastic force of Returnning spring 4, spool 2 also can be made to reset, and the utility model is by adopting the combination design of cam 6, wind-up timer 7, top pressure lever 5, spring, controls the motion of spool 2, effectively can reduce fabricating cost; And its assembling is simple and convenient, can improve efficiency of assembling, reduce assembly cost, meanwhile, be also convenient to maintenance.
Wherein, described Timed valve can be set to Chang Kai or normal closed gate.In the present embodiment, described Timed valve is set to normally off, that is, when the output revolving shaft of described wind-up timer 7 stops operating, described spool 2 is positioned in the closed position of timeing closing valve, is in closed condition to make this Timed valve under normality state.
Concrete, described Returnning spring 4 is for providing the restoring force impelling spool 2 to move towards the closed position of timeing closing valve.When cam 6 rotates, cam 6 supports top pressure lever 5, makes top press lever 5 around fulcrum, and impels spool 2 to move towards the enable possition of opening timing valve by this top pressure lever 5.Wherein, described closed position can be positioned at top or the below of enable possition.And in the present embodiment, described closed position is positioned at above enable possition, described cam 6 is positioned at the below of top pressure lever 5.
Wherein, described wind-up timer 7 can adopt existing structure.
Wherein, according to common practise, described cam 6 is for having the component of curved profile or groove.In the present embodiment, described cam 6 for offering groove and being formed on disk.
Preferably, described valve body 1 comprises valve seat 11, is positioned at valve gap 12 above valve seat 11; Described valve body 1 is also provided with rubber membrane 3, and described valve seat 11 coordinates with rubber membrane 3 and forms lower valve chamber, and described valve gap 12 coordinates with rubber membrane 3 and forms uuper valve chamber; Described valve gap 12 is provided with the perforation of stretching out for spool 2 upper end, described spool 2 is fixedly connected with rubber membrane 3.Concrete, described spool 2 comprises closeouts 21, the valve rod 22 be connected in closeouts 21; Described closeouts 21 is positioned at lower valve chamber, and valve rod 22 is inserted in the through hole of rubber membrane 3, and valve rod 22 and rubber membrane 3 are tightly connected.And by adopting said structure, the fluid in valve body 1 can be avoided to let out from the perforation of valve gap 12, thus its safety in utilization can be improved.
In actual use, first on wind-up timer 7, preset timing by knob, wind-up timer 7 works, output revolving shaft band moving cam 6 is utilized to rotate, and top pressure lever 5 contacts with the convex position (namely arc surface) of cam 6, spool 2 around fulcrum, and is pressed to enable possition by described top pressure lever 5, makes Timed valve be in opening state; And after timing arrives, the output revolving shaft of wind-up timer 7 stops operating, top pressure lever 5 falls within the groove of cam 6, and now, spool 2 moves up to closed position under the elastic force effect of Returnning spring 4, makes Timed valve be in closed condition.
Above-mentioned mode of execution is only preferred implementation of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
