Abstract
The utility model relates to a natural gas pipeline fire-retardant device, which comprises a shell, a fire-retardant core and a rotating rod, wherein the shell is connected in the natural gas pipeline, the fire-retardant core is rotatably arranged in the shell, one end of the rotating rod is connected with the fire-retardant core, and the other end of the rotating rod extends out of the shell; a driving motor is arranged outside the shell and connected with the end part of the rotating rod; and a temperature sensor is arranged on the side wall of the shell. The fire retardant core is arranged in a rotatable mode, when the temperature is low in winter and the pipeline deflagration accident is not easy to happen, the fire retardant core is laterally arranged in the natural gas pipeline, and the resistance of the fire retardant core to natural gas fluid is small at the moment, so that the pipeline conveying power consumption is reduced; thus when easy summer or pipeline temperature rise promoted safety hazard, the back-fire relief core rotated and thus positively set up in the natural gas line, played the effect of prevention back-fire relief.
Description
Technical Field
The utility model relates to a natural gas line back-fire relief device.
Background
Flame arrestors are safety devices used to prevent the spread of flames of flammable gases and flammable liquid vapors. Devices which are generally installed in pipelines for conveying combustible gases, or in ventilated tanks, to prevent the passage of propagating flames (deflagrations or detonations); the flame arrester absorbs the heat of flame through the pore and makes the flame cool down and extinguish, forms great resistance to the air current in the natural gas pipeline in practical application.
Disclosure of Invention
The utility model aims to solve the above problem, provide a natural gas line back-fire relief device, specifically realize by following technical scheme:
a natural gas pipeline fire retardant device comprises a shell, a fire retardant core and a rotating rod, wherein the shell is connected in a natural gas pipeline, the fire retardant core is rotatably arranged in the shell, one end of the rotating rod is connected with the fire retardant core, and the other end of the rotating rod extends out of the shell; a driving motor is arranged outside the shell and connected with the end part of the rotating rod; and a temperature sensor is arranged on the side wall of the shell.
The natural gas pipeline fire retardant device is further designed in a mode that the shell is formed by fixedly connecting a first half shell and a second half shell relatively.
The utility model provides a natural gas line back-fire relief device, its further design lie in, the lower part of back-fire relief core is provided with hemispherical link, the link contradict in the lower extreme inner wall of casing.
The natural gas pipeline fire retardant device is further designed in that a fire retardant cavity is arranged inside the shell, and the fire retardant cavity is ellipsoidal.
The beneficial effects of the utility model reside in that:
the fire retardant core is arranged in a rotatable mode, when the temperature is low in winter and the pipeline deflagration accident is not easy to happen, the fire retardant core is laterally arranged in the natural gas pipeline, and the resistance of the fire retardant core to natural gas fluid is small at the moment, so that the pipeline conveying power consumption is reduced; thus when easy summer or pipeline temperature rise promoted safety hazard, the back-fire relief core rotated and thus positively set up in the natural gas line, played the effect of prevention back-fire relief.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
the natural gas pipeline fire retardant device comprises a shell 1, a fire retardant core 2 and a rotating rod 3, wherein the shell is connected in a natural gas pipeline, the fire retardant core is rotatably arranged in the shell, one end of the rotating rod is connected with the fire retardant core, and the other end of the rotating rod extends out of the shell; a driving motor 4 is arranged outside the shell and is connected with the end part of the rotating rod; the side wall of the housing is provided with a temperature sensor 5.
When the fire retardant core is applied, the temperature is low in winter, and the pipeline detonation accident is not easy to happen, the fire retardant core is laterally arranged in the natural gas pipeline, so that the resistance of the fire retardant core to natural gas fluid is low, and the pipeline transmission power consumption is reduced; thus when easy summer or pipeline temperature rise promoted safety hazard, the back-fire relief core rotated and thus positively set up in the natural gas line, played the effect of prevention back-fire relief.
The shell is formed by fixedly connecting a first half shell and a second half shell relatively, and when the fire retardant core is deformed at high temperature and cannot be rotated and reset, the first half shell and the second half shell can be opened to replace the fire retardant core; of course, the joint of the first half shell and the second half shell is filled with the sealing material.
The lower part of back-fire relief core 2 is provided with hemispherical link 21, the link contradict in the lower extreme inner wall of casing. This arrangement ensures that the firestop element remains vertically stable in this rotatable position.
A fire retardant cavity is arranged in the shell and is in an ellipsoid shape; in order to be rotatable, the fire retardant core is in clearance fit with the side wall of the fire retardant cavity, and the fire retardant core expands to form an interference fit state in a high-temperature state.
Claims (5)
