Problems solved by technology

[0002] At present, natural gas, as a kind of energy, is widely used in people's lives, but the danger of natural gas leakage still exists. There are many natural gas leakage prevention devices on the market, but most of these natural gas leakage prevention devices simply cut off the transmission of natural gas , the leaked natural gas will still leak in the presence of air pressure difference, which will cause safety hazards, and most of the safety protection devices can only be used once, resulting in waste and low utilization

Abstract

The invention discloses a safety protection device for detecting gas leakage of an oil gas pipeline. The device comprises a protective component, wherein the protective component comprises a cutting mechanism, the cutting mechanism comprises a ventilating chamber, a pressing chamber is formed in the upper end wall of the ventilating chamber, a lifting chamber with an upward opening is formed in the lower end wall of the ventilating chamber, a pressing rod is arranged in the pressing chamber and the upper end of the pressing rod is located in the outside space, and a pressing plate is arrangedat the lower end of the pressing rod. The device can be utilized again after the leakage is completed, so that the actual utilization rate of the device is improved; the device can automatically and stably judges whether gas leaks or not, so that the device can still work even under the condition of no person and the security is improved; and the device can stabilize the leaked air pressure aftercutting the transporting of the gas, so that the gas leakage rate is decreased, the gas leakage speed is reduced and the security is improved.

Description

technical field [0001] The invention relates to the field of safety protection, in particular to a safety protection device for detecting air leakage of oil and natural gas pipelines. Background technique [0002] At present, natural gas, as a kind of energy, is widely used in people's lives, but the danger of natural gas leakage still exists. There are many natural gas leakage prevention devices on the market, but most of these natural gas leakage prevention devices simply cut off the transmission of natural gas , the leaked natural gas will still leak in the presence of pressure difference, which will cause safety hazards, and most of the safety protection devices can only be used once, resulting in waste and low utilization. Contents of the invention [0003] The purpose of the present invention is to provide a safety protection device for detecting gas leakage of oil and gas pipelines, so as to solve the problems raised in the above-mentioned background technology. ...
