Description
Technical field
The utility model relates to a kind of water tap, relates in particular to a kind of piston type Anti-leakage water tap.
Background technique
At present, water tap is widely used in productive life.Yet, ordinary faucet generally all adopts artificial opening and closing, especially after opening, run into anhydrous or just in use cut off the water, people are often negligent of closing in time, water again after once people leaves, tend to cause leakage accident, thereby cause the phenomenons such as water resource waste, neighbourhood's dispute and even property loss.Tracing it to its cause is mainly that party's improper use causes, but is also no lack of due to the technological deficiency of existing water tap itself.Although have the induction type automatic faucet of some technology maturations on market, its cost is higher, is unsuitable for generally promoting; Also have some mechanical automatic shutoff valves, but to open the rear automatic continuous time shorter at every turn, inconvenience continues water etc.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, with low cost, both can meet people's routine use, can effectively prevent not only because running into the anhydrous or people but also a kind of piston type Anti-leakage water tap that causes leakage accident such as be negligent of closing in time of just in use cutting off the water after opening.
For addressing the above problem, a kind of piston type Anti-leakage water tap described in the utility model, is characterized in that: this water tap comprises column-shaped barrel, described column-shaped barrel is provided with intake tunnel and exhalant canal, and its inside is provided with piston and slide block.
In described exhalant canal, be provided with one way stop peturn valve.
Described piston is provided with connecting rod; On described connecting rod, be fixed with turbination lock tooth, its top is provided with handle.
Described slide block is provided with Compress Spring, dead bolt and push rod, and described dead bolt is connected with described slide block by rotating shaft, and described rotating shaft is provided with torsion spring.
Described push rod is provided with bar hole.
The utility model compared with prior art has the following advantages:.
1, owing to being provided with described piston and slide block in the utility model, therefore, under normal circumstances, opening of this water tap is after slide block is shifted, water in intake tunnel relies on the pressure of self to promote piston and moves into exhalant canal, when anhydrous, although external force forces slide block displacement, but piston does not move, water tap is not opened; External force disappearance rear slider automatically resets, and piston can not move, and can effectively prevent when anhydrous fetch boiling water tap and be negligent of closing in time the leakage accident causing of people.
2, owing to being provided with described one way stop peturn valve in exhalant canal described in the utility model, therefore, while just in use cutting off the water, one way stop peturn valve stops air to enter water tap, the negative pressure that water in intake tunnel refluxes and causes, force barometric pressure to promote piston reset auto-closed water tap locking, in the time of can effectively preventing just cutting off the water in water utilizing process, people are negligent of closing in time and the leakage accident that causes.
3, because piston described in the utility model is provided with described connecting rod; On described connecting rod, be fixed with described turbination lock tooth, its top is provided with described handle, and therefore, resistance when turbination lock tooth both can effectively reduce piston reset, can effectively stop again the improper movement of the piston tap of fetching boiling water; And handle is conducive to normally make water pusher to move piston closed tap on the one hand, is also convenient on the other hand hydraulic pressure in intake tunnel and pulls the piston tap of fetching boiling water when not enough.
4, because slide block described in the utility model is provided with described Compress Spring, dead bolt and push rod, described dead bolt is connected with described slide block by rotating shaft, described rotating shaft is provided with described torsion spring, therefore, Compress Spring on slide block and push rod, can make slide block drive dead bolt to piston release or locking, reach the opening and closing that facilitate water tap; And torsion spring in rotating shaft resets after being convenient to dead bolt and rotating in time, the resistance in the time of both can further effectively reducing piston reset, can effectively stop again the improper movement of the piston tap of fetching boiling water.
5,, because push rod described in the utility model is provided with described bar hole, therefore, whether push rod is used can guarantee not contact with piston rod and affect the movement of piston.
6, technology described in the utility model also can be used for producing various valves, and if most critical components such as spring are all in water-less environment, can effectively extend its working life.
