Abstract
The utility model relates to an automatic shutting valve to prevent gas pipeline made of plastic and rubber from burning. The technical proposal is: the valve body is a direct-type cylinder, and two ends are respectively provided with an air inlet and an air outlet. A valve core stent is arranged at the middle part of the valve body, and a via hole is axially arranged on the valve core stent to communicate the intracavity of the valve body. The valve core is shaped like an umbrella, and one end is provided with a cylinder, while the other end is provided with a cone. Furthermore the cylinder is sleeved with a spring outside, then is inserted into the valve core stent along the medial axis. A valve core base shaped as a cone groove is arranged at the combinational end of the air outlet and the valve body. A via hole is arranged at the middle of the valve core base to communicate the air inlet and the air outlet and to cooperate with the cone of the valve core to seal. One or more than one pulling rope made of cross fusible material is fixed along the vertical axis direction of the outer end surface of the air outlet, and a top pillar along the medial axis is arranged between the pulling rope and the end surface of the valve core. The length of the top pillar is fully to make the valve core and the valve core base separate. The pulling rope is fused to realize the automatic shutting when the plastic or rubber pipeline breaks to burn and the burning spreads to the air outlet of the valve, after the automatic shutting valve of the utility model is connected with the pipeline, therefore preventing the gas from discharging, and ensuring the safe use of gas.
Description
One, technical field: the utility model relates to a kind of valve, particularly a kind of self acting stop valve that prevents the gas pipeline burning that plastics and rubber are made.
Two, background technique: along with growth in the living standard, various inflammable gass have been widely applied in people's life, people's air duct combustion phenomena that frequent generation is made by plastics or rubber when using combustion gas, and existing air valve can not be closed automatically, causes hidden danger.
Three, summary of the invention: the utility model is exactly at the problems referred to above, designs a kind ofly to be connected on the gas pipeline and the self acting stop valve that can close automatically when pipeline burns.Its technological scheme is: valve body is a straight-through cylindrical body, two ends are respectively equipped with suction port and air outlet, be provided with the spool support at the valve body middle part, being axially arranged with through hole on the spool support connects body cavity, spool is umbrella, one end is a cylindrical body, the other end is a cone, and after being with spring, the cylindrical body outside inserts in the spool support along the medial axis, the air outlet combines the valve core case that the end is the cone groove with valve body, be provided with in the middle of the valve core case through hole be communicated with suction port and air outlet and with the cone fitted seal of spool, fix one or several stay cords that the intersection fusible material is made in exterior edge face, air outlet vertical axis direction, be provided with a fore-set along the medial axis between stay cord and spool end, the length of fore-set is enough to make between spool and the valve core case and breaks away from.Such scheme also can further be improved to: be threaded between air outlet and the valve body, fore-set directly is fixed on the top of spool cone, and stay cord is a nylon wire.
After this self acting stop valve is connected pipeline, after plastics or rubber tubing appearance burning and being burned to the air outlet of this valve, stay cord is fused, after spool loses support, under the effect of spring, will seal between spool and the valve core case, realize closing automatically, stop gas purging, thereby ensured and use gas safety.
Four, description of drawings: accompanying drawing is the cross section structure figure of a kind of mode of execution of the present utility model.
Five, embodiment: with reference to accompanying drawing, valve body 1 is a straight-through cylindrical body, and two ends are respectively equipped with suction port and air outlet, and inserts respectively on the gas pipeline that plastics or rubber makes.Be provided with spool support 2 at valve body 1 middle part, be axially arranged with through hole on the spool support 2 valve body 1 inner chamber is connected, spool 4 is umbrella, and an end is a cylindrical body, and the other end is a cone, and is with spring 3 backs along in the medial axis insertion spool support 2 in the cylindrical body outside.The air outlet combines the valve core case 5 that the end is the cone groove with valve body 1, be provided with in the middle of the valve core case 5 through hole be communicated with suction port and air outlet and with the cone fitted seal of spool 4, fix a stay cord 7 in exterior edge face, air outlet vertical axis direction, stay cord 7 preferably adopts nylon wire, be provided with a fore-set 6 along the medial axis between stay cord 7 and spool end, the length of fore-set 6 is enough to make between spool 4 and the valve core case 5 and breaks away from.Install for convenience and the replacing of air outlet, be threaded between air outlet and the valve body.
Claims (2)
1, a kind of self acting stop valve, comprise valve body and spool composition, it is characterized in that: valve body is a straight-through cylindrical body, two ends are respectively equipped with suction port and air outlet, be provided with the spool support at the valve body middle part, being axially arranged with through hole on the spool support connects body cavity, spool is umbrella, one end is a cylindrical body, the other end is a cone, and after being with spring, the cylindrical body outside inserts in the spool support along the medial axis, the air outlet combines the valve core case that the end is the cone groove with valve body, be provided with in the middle of the valve core case through hole be communicated with suction port and air outlet and with the cone fitted seal of spool, fix one or several in exterior edge face, air outlet vertical axis direction and intersect the stay cords that fusible material makes, be provided with a fore-set along the medial axis between stay cord and spool end, the length of fore-set is enough to make between spool and the valve core case and breaks away from.
2, self acting stop valve according to claim 1 is characterized in that: be threaded between air outlet and the valve body, fore-set directly is fixed on the top of spool cone, and stay cord is a nylon wire.
