Fitting Case for Gas Leak Detection {FITTING CASE FOR SENSING GAS LEAKAGE}

The present invention relates to a fitting case capable of detecting a gas leak in a gas pipe fitting, and more particularly, to detect a gas leak occurring in a fitting of a gas pipeline and to protect the fitting of the gas pipe from external shock. And a fitting case.

Piping is applied to various industries, and it is necessary to extend the piping as necessary. Pipes of constant length are connected to one pipe and another pipe through a connecting member called a fitting. Fittings used for connecting pipes may be exposed to vibration for a long time due to the fluid flowing along the pipes, thereby weakening the binding force of the fittings, and fluid leakage may occur due to the weakening of the fittings. Gas leaks from these fittings compromise the stability of the plant and can lead to catastrophic accidents, such as explosions or casualties, if misguided. Therefore, it is necessary to confirm whether the gas leaks quickly and accurately.

Electronic chemical sensors are most commonly used in the industry to prevent accidents caused by gas leaks. However, the electronic chemical sensor has a disadvantage that the price is relatively expensive and must be used in a limited space. In addition, the electronic chemical sensor is used for early evacuation alarm and post-treatment, rather than to prevent the leakage of toxic substances, and requires regular inspection to minimize the malfunction. As a method for supplementing and improving this, a method of detecting acid or base leakage by color change has been reported. The color conversion sensor represents a color change by changing the molecular structure of the color conversion material by an acid or a base to change the absorption wavelength of visible light, and a representative color conversion material includes a pH indicator.

The inventors of the present invention while studying the acid-base sensor and the case of the gas pipe fitting to prevent weakening the binding force of the gas leak quickly, while protecting the fitting from external physical shocks while at the same time leaking gas from the fitting The present invention was completed by developing a fitting case for gas leak detection that can be quickly identified by the naked eye.
