Abstract
The invention discloses a pipeline gas safety control valve. A gas inlet and a gas outlet are formed in a gas pipeline. A ball valve is arranged on the gas outlet. The safety control valve comprises a valve body, a support, a gas plug, a linking rod and a tension spring. The support is hollow and fixed into the valve body. The valve body is fixed to the portion between the gas inlet and the gas outlet in the gas pipeline. The linking rod is installed in a circular hole in the center of the support. One end of the linking rod is sleeved with the tension spring and the tension spring jacks the radial wall of the support. The gas plug is fixedly arranged at the other end of the linking rod. According to the pipeline gas safety control valve, safety protection measures are taken for utilization of pipeline gas, gas output is cut off in time when the gas leaks, accidents such as gas poisoning and a fire disaster caused by gas leakage are effectively prevented, and the device is simple in structure, low in production cost, safe, convenient to use, practical, safe, reliable and easy to obtain and popularize.
Description
Technical field
The present invention relates to the safety protection device of piped gas, particularly a kind of piped gas Safety control valve.
Background technique
This year, develop rapidly along with urban construction, pipeline gas progressively spreads to huge numbers of families, for people's lives provide very big convenience, pipeline gas is the gas that a kind of danger is larger, if leak time occurs will be occurred poisoning or cause fire, the safety precaution of strengthening pipeline gas is extremely important, existing pipeline gas control valve only has to be opened or closing function, and the safety protection device to gas leakage not, existing a kind of electronic induction head detects gas leakage, by circuit, control the device that gas valve opens and closes, but this technical pattern is complicated, manufacture cost is high.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides piped gas Safety control valve a kind of simple in structure, cheap for manufacturing cost, safe and reliable.
The present invention for the technological scheme that solves its technical problem and adopt is: a kind of piped gas Safety control valve, described gas pipe line is provided with suction port and air outlet, described air outlet is provided with spherical valve, described Safety control valve comprises valve body, support, vent plug, link rod and extension spring, described support is hollow shape, and support is fixed in valve body, described valve body is fixed between the suction port and air outlet in gas pipe line, described link rod is arranged in the circular hole of carriage center, described extension spring is set in link rod one end and withstands the radial wall of support, the other end of link rod is fixed with vent plug
As a further improvement on the present invention, described vent plug is hemispherical Shell shape, and the termination of valve body is provided with the concave arc shape end face identical with vent plug shape.
As a further improvement on the present invention, described valve outer wall is provided with outside thread.
The invention has the beneficial effects as follows: apparatus of the present invention are for being used piped gas to increase safety measure; when gas leakage, cut off in time coal gas output; effectively prevent because of contingencies such as gas poisoning that gas leakage causes, fire; this apparatus structure is simple; low production cost; safe ready, practical safe and reliable, easily promotion and implementation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, indicate: 1-gas pipe line; 2-suction port; 3-air outlet; 4-spherical valve; 5-valve body; 6-support; 7-vent plug; 8-link rod; 9-extension spring.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
Fig. 1 shows a kind of mode of execution of a kind of piped gas Safety control valve of the present invention, described gas pipe line 1 is provided with suction port 2 and air outlet 3, described air outlet 3 is provided with spherical valve 4, described Safety control valve comprises valve body 5, support 6, vent plug 7, link rod 8 and extension spring 9, described support 6 is hollow shape, and support 6 is fixed in valve body 5, described valve body 5 is fixed between the suction port 2 and air outlet 3 in gas pipe line 1, described link rod 8 is arranged in the circular hole at support 6 centers, described extension spring 9 is set in link rod 8 one end and withstands the radial wall of support 6, the other end of link rod 8 is fixed with vent plug 7, described vent plug 7 is hemispherical Shell shape, and the termination of valve body 5 is provided with the concave arc shape end face identical with vent plug 7 shapes, described valve body 5 outer walls are provided with outside thread.
In use extension spring 9 is pulled to vent plug 7 tensions; between vent plug 7 and valve interior wall, leaving gap passes through for combustion gas; when gas leakage; in pipeline, the outside emission flow of combustion gas increases; the pulling force that promotion vent plug 7 overcomes extension spring 9 moves ahead; withstand the concave arc end of valve body 5 inwalls, automatically, by gas outlet sealing, play safety protection effect.
