Abstract

The utility model relates to a self closing tap. A valve core connected with a valve body is arranged on the valve body. The inner lower part of the valve core is provided with a stationary ceramic chip. A movable ceramic chip which is arranged on the stationary ceramic chip corresponds to the stationary ceramic chip. The upper part of the movable ceramic chip is connected with the lower end of a valve rod which penetrates through a through hole arranged in the center of the valve core and extends to the outer upper end of the valve core to be fixedly connected with a valve cap with a handle. The fixed end of a cylindrical helical torsion spring which is sheathed outside the valve rod and positioned in the valve cap is fixed on the valve core or the valve body, and the movable end is fixed in the valve cap. The handle connected with the valve cap extends downwards. The utility model has the advantages of simple structure, low cost, automatic closing after a user's hand leaves the tap, and obvious water saving effect.

Description

The self-closing water tap

Technical field the utility model relates to a kind of valve, particularly the valve of running water pipe network termination.

Background technique is along with science and technology development, and advanced ceramic valve has replaced original ball valve and stopcock gradually.At present, though the ceramic valve kind is a lot, basic structure is roughly the same, valve body is promptly all arranged, which is provided with the spool that is attached thereto and be provided with ceramic plate, the valve rod that the lower end links to each other with moving ceramic plate passes the center spool through hole, reaches the outer upper end of spool and fixedlys connected with the bonnet of band handle.Though this valve has self advantage such as water-tight, is not suitable for using in public places.People design many kinds of self-closing water taps for this reason, wherein have timing, quantitative, also have induction type, any their structure more complicated all, cost height, fragile not only, and hand leaving water tap is self-closing asynchronous with it, and the water that hysteresis is closed during this period of time and flowed out has all wasted.

The summary of the invention the purpose of this utility model is to provide a kind of simple in structure, hand leaving water tap and its self-closing synchronous self-closing water tap.The utility model mainly is to establish torsion spring on the spool of existing ceramic valve.Torsion spring one end that this is enclosed within the valve rod outside and is positioned at bonnet, promptly fixed end is fixed on the spool (also can be valve body), and the other end is that movable end is fixed in the bonnet.When using, the handle that promotion links to each other with bonnet, bonnet rotate and drive the torsion spring rotation, make spring be subjected to certain torsion; Meanwhile, bonnet rotates and to drive the valve rod that is attached thereto again and rotate, and then orders about moving ceramic plate and rotate valve opening water is flowed out.After using up water, hand leaves handle, and the external force that is applied on the handle promptly is cancelled, so under the effect of spring, make the bonnet counterrotating, returns to initial position, and the valve rod that links to each other with bonnet also rotates synchronously and orders about moving ceramic plate backward rotation, with valve closing.Preferably the handle that links to each other with bonnet extends downwards, so that stir handle with arm in use, is beneficial to both hands and washs simultaneously.

The utility model has following advantage compared to existing technology:

1. simple in structure, low cost of manufacture keep the structure of former water tap constant basically, therefore are easy to existing water tap is transformed.

2. user's hand leaving water tap, it promptly can be closed automatically, and water-saving result is obvious.

Description of drawings

Fig. 1 is that master of the present utility model looks schematic representation.

Embodiment is looked in the schematic representation the master of self-closing water tap shown in Figure 1, valve body 1 is provided with the spool 2 that is threaded with it, the bottom is provided with the Dingtao ceramics in the spool, be located at above the ceramics of Dingtao and the moving ceramic plate corresponding with it, its top links to each other with valve rod 3 lower ends, this valve rod passes the center spool through hole and reaches the outer upper end of spool and fixedly connected with bonnet 4, and the handle 5 that links to each other with bonnet extends downwards.Cylindroid helicalcoil torsion spring 6 fixed ends that are enclosed within valve rod outside and are positioned at bonnet are welded on the spool, and movable end is inserted into and is fixed in the interior short tube 7 of bonnet.

Claims

1. self-closing water tap, its valve body is provided with the spool that is attached thereto and be provided with ceramic plate, the valve rod that the lower end links to each other with moving ceramic plate passes the center spool through hole and reaches the outer upper end of spool and fixedly connected with the bonnet of being with handle, it is characterized in that: the torsion spring fixed end that is enclosed within valve rod outside and is positioned at bonnet is fixed on spool or the valve body, and movable end is fixed in the bonnet.

2. self-closing water tap according to claim 1 is characterized in that: the handle that links to each other with bonnet extends downwards.
