Protective sleeve for gas pipe connections

Abstract

The utility model discloses a kind of protective sheaths for gas pipeline connection, it is related to gas relevant technical field.The utility model greatly improves gas pipeline connection security by multiple sealing and leakage visualization design;When gas pipe body is inserted into sleeve body, push docking ring drives piston to slide, supply gas to sealing air bag through air guide pipe, make it expand and fit gas pipe body to form flexible sealing, cooperate with the sealing pad of docking ring, inner joint ring and other parts, build multiple anti-leakage barriers, effectively reduce gas leakage risk;If leakage occurs, gas enters leak detection groove and inflates inflatable air bag through gas leakage hole, transparent observation frame is convenient for user to intuitively find leakage, and gas leakage hole is separately arranged on both sides of sealing air bag, can assist positioning leakage position, without relying on professional detection equipment, adapt to daily safety monitoring demand, observation frame and bolt are staggered, do not interfere with pipeline maintenance operation, give consideration to security and practicality.
