Abstract
The utility model discloses a mechanical water-stoppage self-closing leakage-proof valve which comprises a hollow valve body. One end of the valve body is closed, and the other end of the valve body is provided with a valve deck. The two sides of the valve body are provided with a water inlet and a water outlet. The water inlet is higher than the water outlet. A valve rod is arranged in the valve body. One end of the valve rod penetrates through the valve deck. The other end of the valve rod is fixedly connected with a valve element matched with an inner cavity of the valve rod. A channel capable of being communicated with the water inlet and the water outlet is formed in the valve element. A supporting spring making contact with the bottom of the valve element is arranged at the bottom of the inner cavity of the valve body. A locking mechanism which is capable of locking the motion of the valve rod when water stops is arranged on the valve deck. The mechanical water-stoppage self-closing leakage-proof valve has the advantages of being simple in structure, convenient to use, low in cost, capable of saving water resources and the like.

Background technique
In daily life, have unavoidably the event of cutting off the water and occur, common water valve can not water-cut off self-closure, while recovering water after may causing cutting off the water, because forgetting, closes the more than phenomenon of tap generation current, causes water resource waste and property damage.As follows in the research of self-closing valve for water cut direction both at home and abroad at present: domestic is mainly take circuit control as main; Foreign country is take pure mechanism structure as main, and mechanism is loaded down with trivial details, and achievement in research rests on the model machine of laboratory mostly, and distance on a large scale practical, industrialization also has a certain distance.
Model utility content
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, provide a kind of simple and compact for structure, with low cost, principle is simple, the mechanical type water-cut off self-closure leakproof valve of easy to use, saving water resource.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of mechanical type water-cut off self-closure leakproof valve, comprise hollow valve body, valve body one end sealing the other end is equiped with valve gap, valve body both sides are provided with water intake and water outlet, water intake is higher than water outlet, in described valve body, be equiped with valve rod, valve rod one end passes described valve gap, the other end is fixedly connected with a spool coordinating with body cavity, described spool is provided with the passage that can be communicated with described water intake and water outlet, described body cavity bottom is provided with the supported spring that can contact with spool bottom, valve gap be provided with while cutting off the water supply can locking described in the lockable mechanism of stem movement.
As to further improvement of the utility model:
Described lockable mechanism comprises lock pin and locking annular groove, and described valve gap is provided with the cross through hole perpendicular to valve rod, wears described lock pin in described through hole, is arranged with Returnning spring on lock pin, and described locking annular groove is arranged on valve rod.
Described passage is a vertical cut (V. cut), and the degree of depth of described breach is less than the height of described spool, and the arc length of breach is less than 1/4 girth of spool.
In described valve body, in the top of spool, be provided with spool stroke block, described spool stroke block and described breach be not or not a direction.
Described body cavity bottom is provided with erection column, and described supported spring is sheathed on described erection column, and the height of erection column is less than the height of described supported spring.
Between described valve gap and valve body for being threaded.
Compared with prior art, the utility model has the advantage of:
Mechanical type water-cut off self-closure leakproof valve of the present utility model, under the lockable mechanism double action on the set supported spring in spool bottom and valve rod top, can automatic closing water road after cutting off the water supply, prevent from leaking, have simple in structure, easy to use, with low cost, advantage that can saving water resource.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Marginal data:
1, valve body; 11, water intake; 12, water outlet; 2, valve gap; 3, valve rod; 31, locking annular groove; 4, spool; 41, breach; 5, supported spring; 6, lock pin; 7, Returnning spring.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of mechanical type water-cut off self-closure leakproof valve of the present utility model, comprise hollow valve body 1, valve body 1 one end sealing the other end is equiped with valve gap 2, valve body 1 both sides are provided with water intake 11 and water outlet 12, water intake 11 is higher than water outlet 12, in valve body 1, be equiped with valve rod 3, valve rod 3 one end pass valve gap 2, the other end is fixedly connected with a spool 4, the external diameter of spool 4 is consistent with valve body 1 inner chamber, cooperatively interact, spool 4 is provided with passage, while not using, this passage is not communicated with water intake 11 and water outlet 12, during use, user can rotate valve rod 3 angle makes channel connection water intake 11 and water outlet 12, at valve body 1 intracavity bottom, be provided with supported spring 5, valve gap 2 is provided with while cutting off the water supply the lockable mechanism can locking valve rod 3 moving.When water flowing, spool 4 moves downward to contacting with supported spring 5 under hydraulic pressure, cut off the water supply and move upward water outlet 12 is sealed under the effect of the supported spring 5 of back valve core 4, the motion of lockable mechanism locking valve rod 3, when water flowing again, spool 4 can not move downward under hydraulic pressure, prevent from leaking, it is simple in structure, with low cost, easy to use, can saving water resource, can prevent leaks causes any property loss.
In the present embodiment, lockable mechanism comprises lock pin 6 and locking annular groove 31, and valve gap 2 is provided with the cross through hole perpendicular to valve rod 3, wears lock pin 6 in through hole, is arranged with Returnning spring 7 on lock pin 6, and locking annular groove 31 is arranged on valve rod 3.When cutting off the water supply, valve rod 3 rises, and lock pin 6 is inserted in locking annular groove 31, when after water flowing, even if spool 4 can not move downward under hydraulic pressure, can prevent from leaking; User need pull open lock pin 6 could water.
