Description
Technical field
The utility model relates to plumbing component technology field, specifically a kind of timing shutting-up tap control valve.
Background technique
At present, what people used is manual-lock formula water tap or automatic water tap mostly, and manually operated type is the water tap of common hand switch, mainly comprises rotary and Pushtype water tap; Automatic water tap is mainly infrared-sensing type water tap.
Manual type water faucet is being opened after discharging water and can not automatically closed, and forgets to close or do not tighten to cause metalling run out the generation of phenomenon so people usually fetch boiling water tap when anhydrous, causes the serious waste of water resources.Infrared-sensing type water tap or mechanical type pressing delayed faucet can address the above problem, however infrared-sensing type water tap less stable, and working life is shorter; The principle that mechanical type pressing delayed faucet takes spring press to reply, realizes quantitative flushing in can only be at a fixed time after the tap of fetching boiling water, and Applicable scope is less, can only use in short-term in public place.
Model utility content
For addressing the above problem, the utility model provides a kind of timing self-closing water wheels head control valve, and user can arrange different flow times according to the difference of institute's water requirement, and timing automatic is closed.
The technological scheme that the utility model provides is: a kind of timing self-closing water wheels head control valve, comprise shell, in shell, be provided with fixed flat planar, driving cam and location guide, fixed flat planar is a rectangular flat, near the arranged outside of shell, one side is connected with shell, and opposite side is free end, one end of location guide is fixed on the side of shell, is oppositely arranged with fixed flat planar, the place, an angle of driving cam is provided with an angular cut, on it, be also provided with hollow slots and rach slot, the other end of location guide stretches into this hollow slots, driving cam is by the clockwork spring driving gear engagement driving of rach slot and mechanical timer and at fixed flat planar, front-rear reciprocation movement in the plane that fixes under the positioning action of location guide and hollow slots, the angular cut below butt of driving cam has roller, roller is fixedly installed on the pressure control valve stem tip of pressure controlled valve in valve structure, on pressure control valve rod, spring is installed, thereby this roller can roll along the inclined-plane of angular cut and drive pressure control valve rod to pump.
As a kind of optimal way of the present utility model, described hollow slots is provided with two, the hollow out flute length below of hollow slots ratio above, and described location guide is provided with three, wherein in longer hollow slots, stretches and has two location guides.
The utility model is easy to use, with low cost, saving durable water, and user can arrange different flow times according to the difference of institute's water requirement, and timing automatic is closed, and reaches the function of convenient water saving.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and the utility model is not only confined to this.
As shown in Figure 1, the utility model provides a kind of timing self-closing water wheels head control valve, comprise shell, in shell, be provided with fixed flat planar, driving cam and location guide, fixed flat planar is a rectangular flat, near the arranged outside of shell, one side is connected with shell, opposite side is free end, and one end of location guide is fixed on the side of shell, is oppositely arranged with fixed flat planar; The place, an angle of driving cam is provided with an angular cut, is also provided with hollow slots and rach slot on it, and in the present embodiment, hollow slots is provided with two, the hollow out flute length below of hollow slots ratio above; The other end of location guide stretches into this hollow slots, and in the present embodiment, location guide is provided with three, wherein in longer hollow slots, stretches and has two location guides.
Driving cam is by the front-rear reciprocation movement in the clockwork spring driving gear engagement driving of rach slot and mechanical timer the plane that fixes under the positioning action of fixed flat planar, location guide and hollow slots, the angular cut below butt of driving cam has roller, roller is fixedly installed on the pressure control valve stem tip of pressure controlled valve in valve structure, on pressure control valve rod, spring is installed, thereby this roller can roll along the inclined-plane of angular cut, drive pressure control valve rod pumps.Meanwhile, under the restoring force effect of spring, pressure control valve rod can be got back to original state automatically, and described original state is water tap closed condition.The roller being connected with pressure control valve rod and the friction between angular cut are rolling friction, can farthest reduce the frictional force in motion, make the use of self-closing faucet sensitiveer, quick, stable.
In the utility model, the timing gear being connected with clockwork spring driving gear in mechanical timer is uniform motion, and its run duration determines by the set time of mechanical timer, and the motion state of clockwork spring driving gear is synchronizeed with the motion state of timing gear.
As shown in Figure 2, when driving cam fixes front-rear reciprocation movement in plane, drive pressure control valve rod is pumped, thus the unlatching of corresponding current or closed condition.
As shown in Figure 3, for the rach slot of driving cam and the clockwork spring driving gear mesh schematic representation of mechanical timer, moving direction at clockwork spring driving gear is under counterclockwise-clockwise motion state, corresponding driving cam backward-motion state forward, thereby the close-opening state of corresponding current.
