Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of Protective valve.
Background technique
In daily life, occur temporarily stopping situation about supplying water sometimes, at this moment, people tend to forget and close behind Open valve or water tap.When resuming water supply, cause supplying water and run off, the waste great lot of water resources causes heavy economic losses, make troubles to life, and even other users is brought disaster in infiltration.
The model utility content
The utility model technical problem to be solved provides a kind ofly can close pipeline automatically when cutting off the water, prevent when supplying water once more that current from losing, rational in infrastructure, uses the automatic protection valve of simply cutting off the water supply.
For solving the problems of the technologies described above, the technological scheme of the utility model is: the automatic protection valve of cutting off the water supply is installed between intake pipe and the outlet pipe; Comprise the buffering valve body that is installed between said intake pipe outlet and the outlet pipe inlet; Be provided with the buffering valve pocket in the said buffering valve body, said outlet pipe ingress is provided with sealing buoyancy valve plate in the said buffering valve pocket, and said sealing buoyancy valve plate and said outlet pipe inlet top are hinged; The sealing surface that said sealing buoyancy valve plate and said outlet pipe form is inclined upwardly; Said buffering valve pocket is connected with drain valve, and said drain valve is connected with drainage tube, and the outlet of said drainage tube is communicated to said outlet pipe.
As optimized technical scheme; Said drain valve comprises valve body, also comprises the sealed valve core that is positioned at said buffering valve pocket, ring platform in said sealed valve core is connected with; The ring platform is connected with the controlling rod that stretches out said valve body in said; Said controlling rod is provided with Returnning spring, and said Returnning spring is connected with positioning boss, and the end that said controlling rod stretches out said valve body is provided with operating handle.
Owing to adopted technique scheme, the automatic protection valve of cutting off the water supply is installed between intake pipe and the outlet pipe; Comprise the buffering valve body that is installed between said intake pipe outlet and the outlet pipe inlet; Be provided with the buffering valve pocket in the said buffering valve body, said outlet pipe ingress is provided with sealing buoyancy valve plate in the said buffering valve pocket, and said sealing buoyancy valve plate and said outlet pipe inlet top are hinged; The sealing surface that said sealing buoyancy valve plate and said outlet pipe form is inclined upwardly; Said buffering valve pocket is connected with drain valve, and said drain valve is connected with drainage tube, and the outlet of said drainage tube is communicated to said outlet pipe; When stopping to supply water; The current of said outlet pipe fall; Because the sealing surface that said sealing buoyancy valve plate and said outlet pipe form is inclined upwardly, said sealing buoyancy valve plate falls around the hinged place under the effect of self gravitation and said buffering valve pocket internal water pressure, with the inlet seal of said outlet pipe; When supplying water once more, the water of said intake pipe flows in the said buffering valve pocket, because the disconnected said outlet pipe inlet of said sealing floating valve plate resistance, so can not enter in the said outlet pipe, even Open valve or water tap can prevent that also current from losing; Operate said drain valve; Water in the said buffering valve pocket is drained in the said drainage tube; Flow in the said outlet pipe, water is reverse to float said sealing buoyancy valve plate, opens said sealing buoyancy valve plate again; The water that is blocked in the said buffering valve body just can flow in the said outlet pipe, has normally used; The utility model can be closed pipeline automatically when cutting off the water, prevent when supplying water once more that current from losing, and is rational in infrastructure, uses simple.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation.
Among the figure: the 1-intake pipe; The 2-outlet pipe; 3-cushions valve body; 4-cushions valve pocket; 5-sealing buoyancy valve plate; The 6-drainage tube; The 7-valve body; The 8-sealed valve core; Ring platform in the 9-; The 10-controlling rod; The 11-Returnning spring; The 12-positioning boss; The 13-operating handle.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.In the detailed description below, some example embodiment of the utility model has only been described through the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation of spirit that does not depart from the utility model and scope, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
Shown in accompanying drawing, the automatic protection valve of cutting off the water supply is installed between intake pipe 1 and the outlet pipe 2; Comprise the buffering valve body 3 that is installed between said intake pipe 1 outlet and outlet pipe 2 inlets; Be provided with buffering valve pocket 4 in the said buffering valve body 3, said outlet pipe 2 ingress are provided with sealing buoyancy valve plate 5 in the said buffering valve pocket 4, and said sealing buoyancy valve plate 5 is hinged with said outlet pipe 2 inlet tops; Said sealing buoyancy valve plate 5 is inclined upwardly with the sealing surface that said outlet pipe 2 forms; Said buffering valve pocket 4 is connected with drain valve, and said drain valve is connected with drainage tube 6, and the outlet of said drainage tube 6 is communicated to said outlet pipe 2.Said drain valve comprises valve body 7; Also comprise the sealed valve core 8 that is positioned at said buffering valve pocket 4; Ring platform 9 in said sealed valve core 8 is connected with, said interior ring platform 9 is connected with the controlling rod 10 that stretches out said valve body 7, and said controlling rod 10 is provided with Returnning spring 11; Said Returnning spring 11 is connected with positioning boss 12, and the end that said controlling rod 10 stretches out said valve body 7 is provided with operating handle 13.
When stopping to supply water; The current of said outlet pipe 2 fall; Because said sealing buoyancy valve plate 5 is inclined upwardly with the sealing surface that said outlet pipe 2 forms; Said sealing buoyancy valve plate 5 falls around the hinged place under the effect of self gravitation and said buffering valve pocket 4 internal water pressures, with the inlet seal of said outlet pipe 2; When supplying water once more, the water of said intake pipe 1 flows in the said buffering valve pocket 4, because said outlet pipe 2 inlets of said sealing buoyancy valve plate 5 blocking-up, so can not enter in the said outlet pipe 2, even Open valve or water tap can prevent that also current from losing.Said operating handle 13 is depressed in operation, the said Returnning spring 11 of said positioning boss 12 compressions, and interlock acts on said interior ring platform 9, said sealed valve core 8; Said sealed valve core 8 is opened with said buffering valve pocket 4 joints, and the water in the said buffering valve pocket 4 drains in the said drainage tube 6, flows in the said outlet pipe 2 again; Water is reverse to float said sealing buoyancy valve plate 5, opens said sealing buoyancy valve plate 5, and the water that is blocked in the said buffering valve pocket 4 just can flow in the said outlet pipe 2; Normally used; Unclamp said operating handle 13, said sealed valve core 8 returns to initial position, with said buffering valve pocket 4 sealings.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
