Problems solved by technology

[0003] In recent years, with the rapid development of urban construction, piped gas has gradually spread to thousands of households, providing great convenience for people's lives. Piped gas is a dangerous gas. If it leaks, it will cause poisoning or In case of fire, it is very important to strengthen the safety precautions of pipeline gas. The existing pipeline gas control valve only has the function of opening or closing, but there is no safety protection device for gas leakage. There is an electronic sensor head to detect gas leakage and control the gas valve through the circuit. Open and close device, but the technical structure is complicated and the manufacturing cost is high

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

[0001] technical field [0002] The invention relates to a safety protection device for pipeline gas, in particular to a safety control valve for pipeline gas. Background technique [0003] In recent years, with the rapid development of urban construction, piped gas has gradually spread to thousands of households, providing great convenience for people's lives. Piped gas is a dangerous gas. If it leaks, it will cause poisoning or In case of fire, it is very important to strengthen the safety precautions of pipeline gas. The existing pipeline gas control valve only has the function of opening or closing, but there is no safety protection device for gas leakage. There is an electronic sensor head to detect gas leakage and control the gas valve through the circuit. Opening and closing device, but the technical structure is complicated and the manufacturing cost is high. [0004] Contents of the invention [0005] In order to overcome the above defects, the present invention...
