Abstract
The utility model discloses an automatic intercepting valve designed for resolving the issue in the prior art that a valve can not be automatically closed in the event of water running out of the pipeline via the valve. The intercepting valve comprises an inlet valve and an exit valve, and the intercepting valve built-in with a valve core is characterized in that: an annular bulge is arranged in the interior wall of the valve, and the bulge has an inner diameter fit for the valve core. The bulge divides the inner space of the valve into two parts. A fixing bracket is arranged between the valve core and the inlet valve. The fixing bracket provides a magnet corresponding to another magnet in the valve core and is perpendicular to the strut pole of the fixing bracket. The valve core penetrates the strut pole and reciprocates along the strut pole. The utility model has a simple structure and can automatically intercept the water rushing out of the pipeline, and the utility model applies to sundry pipeline.
Description
Technical field
The utility model relates to a kind of valve.
Background technique
Existing valve is various, and ball valve, butterfly valve, stop valve etc. are arranged.They comprise the valve core of valve body and controlling liquid flow, and the valve body two ends tap into waterpipe and outlet conduit respectively.The existing used valve of underground water conduit can't be closed automatically at the pipeline late gate of metalling run out, and current are stopped.
The model utility content
At above-mentioned deficiency, the utility model provides a kind of simple in structure, automatic shutoff valve that pipeline can block current after metalling run out.
For achieving the above object, the utility model automatic shutoff valve by the following technical solutions:
A kind of automatic shutoff valve comprises valve body, described valve body is built-in with spool, be equipped with import and outlet on the valve body at spool two ends, described valve interior wall is equipped with annular protrusion, this projection internal diameter and described spool fit, described projection is with the inner space separated into two parts of described valve body, be equipped with described spool between described import and the described annular protrusion, be equipped with fixed support between described spool and the described import, this fixed support is equipped with magnet, be equipped with magnet on the corresponding described spool with this magnet, be equipped with spool pole, be equipped with described spool on this spool pole perpendicular to described fixed support.Described spool can to-and-fro motion on described spool pole.
As further improvement project, be equipped with spool between described outlet and the described annular protrusion, be equipped with fixed support between described spool and the described outlet, this fixed support is connected with described spool pole, described spool places on the described spool pole, described fixed support is equipped with magnet, is equipped with magnet on the corresponding described spool with this magnet.Described valve body is equipped with connecting tube, and this connecting tube is equipped with valve.
The utility model automatic shutoff valve has the following advantages: the inlet/outlet of described valve body is connected to intake pipe and outlet conduit respectively.The following two blocks of magnet of normal condition attract each other, water injects valve body from intake pipe, around spool, flow through, flow out from outlet conduit, when the outlet conduit explosion, the stressed disequilibrium at spool two ends, greater than its suffered magnetic force, described spool moves to the outlet pipe direction along described spool pole current to the enormous impact power of spool, when described spool stifled during to described annular protrusion, stop motion, flowing water just is cut off.After outlet conduit is repaired, open the valve on described connecting tube, water is from flowing through described connecting tube, and behind the hydraulic balance on spool two sides, described spool is to swivel motion under the effect of magnetic force.
Description of drawings
Fig. 1 is the utility model automatic shutoff valve structural representation.
Fig. 2 is another embodiment's of the utility model automatic shutoff valve a structural representation.
Specific embodiment
With reference to accompanying drawing 1, the utility model automatic shutoff valve, comprise the valve body 1 that is equipped with import 3 and outlet 4, described valve body 1 is built-in with spool 2, be equipped with annular protrusion 5 on the inwall at described valve body 1 middle part, these projection 5 internal diameters and described spool 2 fits, described protruding 5 inner space separated into two parts with described valve body 1, be equipped with fixed support 6 between described spool 2 and the described import 3, on this fixed support 6, be mounted with magnet 7, with be equipped with magnet 8 on these magnet 7 corresponding described spools 2, be equipped with spool pole 9 perpendicular to described fixed support 6, described spool 2 is located in can to-and-fro motion on described spool pole 9 on the spool pole 9.Described annular protrusion 5, spool 2 all are equipped with seal ring.
Automatic stop valve of the present utility model is work like this, and under the normal condition, magnet 7 attracts each other with the magnet 8 of spool, and water injects valve body from intake pipe, flows through around spool, flows out from outlet conduit; When the outlet conduit explosion, stressed moment disequilibrium at spool 2 two ends, current to the enormous impact power of spool 2 greater than its suffered magnetic force, spool 2 moves to the outlet pipe direction along described spool pole 9, when described spool 2 moves to described annular protrusion 5, stop motion, flowing water just is cut off.
With reference to accompanying drawing 2, as further improvement project, be equipped with spool 12 between described outlet 4 and the described annular protrusion 5, be equipped with fixed support 16 between described spool 12 and the described outlet 4, this fixed support 16 links with described spool pole 9, described spool 12 places on the described spool pole 9, and described fixed support 16 is equipped with magnet 17, is equipped with magnet 18 on the corresponding described spool with this magnet.
As further improvement of the present utility model, be equipped with connecting tube 10 at described valve body 1, this connecting tube 10 is equipped with valve 11.After outlet conduit is repaired, open the valve 11 on described connecting tube 10 like this, water is from flowing through described connecting tube, and behind the hydraulic balance on spool 2 two sides, described spool 2 is to swivel motion under the effect of magnetic force.
Claims (4)
