The subject matter that above-mentioned shutoff utensil and method for blocking thereof exist is: carry out manual hand manipulation again after needing to stop fed sheet of a media, its system architecture is complicated, and assembly parts is many, and installation time is long, and plugging effect is not bery desirable.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art part and provides a kind of structure simple, and assembly parts is few, and installation time is short, and Security is high, and dielectric loss is little, the pipe leakage automatic plugging valve that plugging effect is desirable.
For solving the problems of the technologies described above, the present invention realizes like this.
A kind of pipe leakage automatic plugging valve, it comprises valve body; Described valve body comprises main passage and automatically shuts down mechanism; Described main passage internal fixtion is provided with pass fracture; The described piston automatically shutting down mechanism and comprise cylinder, valve and be placed in cylinder; Described piston coordinates with cylinder inner wall is dynamic, and its geometrical center is fixedly connected through connecting rod and valve; Thrust spring is fixed with between the top of described piston and the top of cylinder; The working surface of described valve is corresponding with pass fracture, to guarantee the folding of main passage; The first drainage shunt and the second drainage shunt is fixedly furnished with in the both sides of described cylinder; Described first drainage communicates with main passage inner chamber and cylinder inner cavity bottom section respectively with the second drainage two-port along separate routes along separate routes.
As a kind of preferred version, the present invention is fixed with the first spherical valve and the second spherical valve along separate routes with in the second drainage along separate routes successively respectively in described first drainage.
As another kind of preferred version, the present invention is fixed with cylinder attaching nut between described cylinder and main passage; Described cylinder attaching nut is fixed with connecting rod nut; The outer wall of described connecting rod coordinates with connecting rod nut inner wall is dynamic.
The present invention automatically shuts down mechanism by arranging on valve body, occurs to leak in emergency circumstances, can implement automatic quick blocking to risk source pipeline at risk source pipeline.Structure of the present invention is simple, and assembly parts is few, and installation time is short, and Security is high, and dielectric loss is little, and plugging effect is desirable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described.Protection scope of the present invention is not only confined to the statement of following content.
Fig. 1 is overall structure schematic diagram of the present invention.
In figure: 1, valve body; 2, main passage; 3, fracture is closed; 4, cylinder; 5, piston; 6, valve; 7, thrust spring; 8, the first drainage along separate routes; 9, the second drainage along separate routes; 10, the first spherical valve; 11, the second spherical valve; 12, cylinder attaching nut; 13, connecting rod nut; 14, seal ring; 15, adpting flange; 16, connecting rod.
Embodiment
As shown in the figure, pipe leakage automatic plugging valve, it comprises valve body 1; Described valve body 1 comprises main passage 2 and automatically shuts down mechanism; Described main passage 2 internal fixtion is provided with and closes fracture 3; The described piston 5 automatically shutting down mechanism and comprise cylinder 4, valve 6 and be placed in cylinder 4; Described piston 5 coordinates with cylinder 4 inwall is dynamic, and its geometrical center is fixedly connected through connecting rod 16 and valve 6; Thrust spring 7 is fixed with between the top of described piston 5 and the top of cylinder 4; The working surface of described valve 6 is corresponding with pass fracture 3, to guarantee the folding of main passage 2; The first drainage shunt 8 and the second drainage shunt 9 is fixedly furnished with in the both sides of described cylinder 4; Described first drainage 8 communicates with main passage 2 inner chamber and cylinder 4 intracavity bottom region with the two-port of the second drainage shunt 9 along separate routes respectively.
The present invention is fixed with the first spherical valve 10 and the second spherical valve 11 successively respectively in described first drainage shunt 8 and the second drainage shunt 9.
The present invention is fixed with cylinder attaching nut 12 between described cylinder 4 and main passage 2; Described cylinder attaching nut 12 is fixed with connecting rod nut 13; The outer wall of described connecting rod 16 coordinates with connecting rod nut 13 inwall is dynamic.As shown in the figure, 14 is seal ring, with the sealing of guarantee system inside; 15 is adpting flange.
The present invention is applicable to colliery, chemical industry, the various pipeline such as oil, and when coal mine gas from explosion or when causing piping facility to damage because of reasons such as other machineries, it has the function of the above pipeline of moment automatic plugging fracture location.Reaction time of the present invention is 10 milliseconds, and after can ensureing calamity, pipeline normally provides gas (or other types medium).Non-transformer of the present invention controls, and installation and maintenance are simple and convenient, and very economical, and after can be the various facility calamities of taking refuge such as colliery, normal operation supplies pressure wind.The mode of action of the present invention is that pressure reduction presses off formula.
The main passage 2 of valve body 1 in use, first by designing requirement, is fitted to the key node of media-carrying lines by the present invention.Close the second drainage shunt 9, open the first spherical valve 10; When there is the urgency of leaking in downside risks source capsule road, downstream pip inner chamber is together with the first drainage 8 inner chamber decompressions along separate routes, piston 5 now in cylinder 4 moves down instantaneously under the effect of pressurized gas, and connecting rod 16 promotes valve 6, is shut by pass fracture 3 by thrust spring 7.At this moment, whole media-carrying lines is by automatic plugging.After leakage urgency is got rid of, need to restart pipe leakage automatic plugging valve, now, open the second drainage shunt 9, close the first spherical valve 10.At this moment, the piston 5 in cylinder 4, under the pressure of transfer line medium, returns back to original position, finally again closes the second drainage shunt 9 again, opens the first spherical valve 10, thus completes the one action circulation of pipe leakage automatic plugging valve.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
