Description

Two-purpose on-off device for tap water with automatic and hand turn-off

The utility model relates to a kind of pipeline accessory, especially a kind of having concurrently automatically and the tap water on-off system of manual two kinds of functions.

Traditional tap water on-off system is a kind of mechanical switch of manual control break-make, the characteristics of this switch are need open the time, must be with hand rotary switch handle constantly, repeat above-mentioned action in the other direction with hand again in the time of need closing, this is very inconvenient to user in public places, operating the hand washing of switch must operate a switch again after clean and could cut off the water source, this is obviously unfavorable to the health that keeps hand, therefore in public places, nobody closes usually can to see running water switch, caused the significant wastage at water source, if not finding switch in addition in family life when cutting off the water supply does not close, in case resume water supply, and unmanned in the room, just may cause floods.

The purpose of this utility model provides a kind of tap water on-off system for closing automatically of using of family and public place or manual-lock.

The technical solution of the utility model is: shell is made "

" shape; a through hole is established in the corresponding position that exports under curved top and shell; be equipped with a push-button socket in this through hole; the push-button socket lower end is provided with step in; be equipped with a spring on interior step; be with a button in spring, the top board of button is divided into a position limit pin, establish a convex shoulder at outer wall, convex shoulder is pressed on the spring, the button inwall is established a step, on step, be equipped with the convex shoulder of some ratchets, ratchet is uniform to be articulated on the ratchet support, on the ratchet support and in the ratchet inboard, be equipped with a circular open spring, the outlet internal fixation has a valve seat under shell, establishing a valve that has the center counterbore on the valve seat supports, in counterbore, be equipped with the lower end of spool, the upper end of spool is arranged in the space of ratchet support and ratchet composition, and screw thread is established at the spool middle part, establishes below screw thread and closes groove on the other hand, a cock body is established in the spool bottom, cock body and valve seat coupling is used, and is fixed with some blades at the outer surface of cock body, and the fixed-direction of this blade is opposite with the direction of screw thread, the length of spool screw thread equals the not end of position limit pin and the distance between the push-button socket upper-end surface, is provided with some through holes in the bottom of valve seat.Turn knob to hand closed the position when hand closed use, and subordinate touches the button, length of spring compressed, and the ratchet upper end comes closer under the effect on inclined-plane in button, forces the ratchet lower end outwards separately and with button to move down.Button is by discharge external force when position limit pin sinks to limit pin hole, button moves up under the effect of spring, ratchet upper end convex shoulder is no longer oppressed on the inclined-plane in the button, and the ratchet upper end outwards separates under the effect of circular open spring, and the screw thread that spool was drawn close and be buckled in the lower end to the center sets about to close in the groove.Button continues to rise and resets, and step drives rising together such as ratchet, ratchet support, spool, cock body in the button, and this moment, cock body was lifted off a seat, and current go out through the orifice flow of valve cup bottom.Spool only rotates and does not move down.In the time will cutting off the water supply, touch the button then with have gentle hands that ratchet separates again again, spool falls within on the valve seat automatically, and the water source is cut off.When close using, turn knob is to from closing the position, touches the button down position limit pin not to be held with the push-button socket upper-end surface contact.Under the effect on inclined-plane, ratchet moves down and is buckled on the spool screw thread in button.Remove external force, push-button reset, step drives rising together such as ratchet, ratchet support, spool, cock body in the button, and cock body is lifted off a seat, at this moment if there is water to flow through, the blade on the water impact cock body then, make valve core rotation, because the spool screw thread controlled by ratchet, so while cock body rotates descends, contact with valve seat until cock body, till the water source is cut off.

The utlity model has advantages such as reasonable in design, easy to assembly, reliable performance.
