Description
Technical field
The utility model relates to a kind of water valve, especially a kind of automatic shutoff valve of cutting off the water.
Background technique
The tap of fetching boiling water is found to cut off the water, and closes water tap because some reason is forgotten, like water suddenly midway; A large amount of water will run off, and the wasting while, also possibly cause the loss of other properties; To this practical problem, have in the existing technology and utilize the infrared ray electric magnetic water tap of control automatically, but complicated difficult realization of its project organization; Can not use during power failure, and cost is higher.
By on can know that the above-mentioned existing automatic shutoff valve of cutting off the water on reality is used, obviously has defective and exists, and remain to be improved.
Thus, the improving of the above-mentioned defective of thoughts of the present invention is that the spy concentrates on studies and cooperates and repeatedly practises, and proposes a kind of reasonable in design and effectively improve the model utility of above-mentioned defective finally.
Summary of the invention
To the deficiency of existing technology, the utility model aims to provide a kind of automatic shutoff valve of cutting off the water, and can close the water tap water route automatically when guaranteeing to cut off the water, and simple in structure, and cost is low, and is reliable and stable.
The technological scheme that the utility model adopts: a kind of automatic shutoff valve of cutting off the water, comprise valve body and spool, the front-end face of valve body has the intake tunnel mouth; Have the exhalant canal mouth at the valve body outer side surface, intake tunnel communicates with exhalant canal in the valve body, and the front-end face of spool is over against the intake tunnel mouth; There is the axle collar front portion of spool, and axle collar external diameter is greater than the intake tunnel internal diameter, and the rear end of valve body is connected with end cap; End cap is provided with the adjusting bolt, and the screw rod end face of regulating bolt has packing ring and stretches into the valve inleting water passage, and packing ring is over against the spool ear end face; The pressure spring I is housed between spool ear end face and packing ring, also has locating slot, also be provided with fixed cover at the outer side surface of valve body in the rear end of spool; In fixed cover, be provided with thimble, when the spool front-end face was closed the intake tunnel mouth, the thimble head inserted locating slot.
Afterbody at thimble is provided with the pressure spring II.
It is conical that the thimble head is, and the cone angle in the circular cone axial cross section is 60 degree.
Edge at the anterior axle collar of spool evenly is provided with the water hole.
Adopt the above-mentioned automatic shutoff valve of cutting off the water,, do not have hydraulic pressure in the water pipe if when cutting off the water; The pressure spring I of spool ear end face
promotes spool and moves forward, when the spool front-end face contacts with the intake tunnel mouth, and spool sealing intake tunnel; At this moment, thimble is under the effect of deadweight and elastic force, and the thimble head inserts the locating slot at spool rear portion; Spool is locked, when coming water more certainly, need to withdraw from locating slot toward the post-tensioning thimble; The tap of fetching boiling water again, owing to have hydraulic pressure in the water pipe, the water pressure pushing spool moves backward; Certainly the thrust of hydraulic pressure generation needs the thrust greater than spring; Move behind the spool front-end face like this, after water flowed into the exhalant canal mouth from the spool water hole, water flowed out from water tap.
The utility model is installed on the water inlet manifold road of family, can locked total water inlet path, and after promptly cutting off the water, no matter open any water tap, and forget and close, come not have water behind the water and flow out from water tap.
The utility model leans on mechanical transmission to realize the unlatching of intake tunnel fully or closes, and working stability is reliable, and overall structure is simple, is convenient to manufacturing.

Fig. 3 is embodiment's 2 structural representations;
In the accompanying drawing: 1 valve body, 2 spools, 3 end caps 4 are regulated bolt 5 packing rings 6 pressure spring I 7 fixed covers 8 thimbles 9 pressure spring II 10 axle collars 11 intake tunnel mouths 12 exhalant canal mouths 13 water taps 14 locating slots 15 sealed grooves 16 water holes.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment 1: as shown in Figure 1, valve body 1 is whole cylindrical, comprises intake tunnel and exhalant canal in the valve body 1; The front-end face of valve body 1 has intake tunnel mouth 11, and intake tunnel mouth 11 connects with intake pipe, has exhalant canal mouth 12 at valve body 1 outer side surface; Exhalant canal mouth 12 connects water tap 13, and intake tunnel communicates with exhalant canal, and the front-end face of spool 2 is over against intake tunnel mouth 11; Spool 2 integral body are " worker " font, and there is the axle collar 10 front portion of spool 2, and the axle collar 10 external diameters are greater than the internal diameter to 11 mouthfuls of intake tunnels; Also have boss on the front-end face of spool 2, be used to install O-ring seal.The rear end scyewed joint end cap 3 of valve body 1, end cap 3 is provided with tapped hole, regulates bolt 4 in the tapped hole assembling; An end face of regulating bolt 4 is equipped with packing ring 5 and stretches into valve body 1 intake tunnel, and packing ring 5 is over against spool 2 ear end faces, and the rear section of spool 2 is also cylindrical; At its outer surface two sealed grooves 15 are arranged; O-ring seal is installed in sealed groove 15, between spool 2 ear end faces and packing ring 5, pressure spring I 6 is housed, the thrust that the thrust that pressure spring I 6 produces produces less than hydraulic pressure; Regulate the tightness that bolt 4 is used to regulate and control pressure spring I 6, also have locating slot 14 in the rear end of spool 2; Outer side surface at valve body 1 also is provided with fixed cover 7; In fixed cover 7, be provided with thimble 8, thimble 8 can axially move forward and backward in fixed cover 7, and the head of thimble 8 is conical; Can spend equal angles by 30 degree or 45 at circular cone axial cross section female cone angle; Be preferably 60 degree, when spool 2 front-end faces were closed 11 mouthfuls of intake tunnels, thimble 8 heads inserted locating slot 14.
