The right terminal pad connect and the inner connection tube in the upstream line and the downstream line, the upstream end of the inner connection tube
It is connect with the upstream line, the downstream of the inner connection tube is connect with the downstream line；The upstream of the inner connection tube
End and downstream are all provided with the boss that the outside of the oriented inner connection tube extends, and are equipped with two seal grooves between two boss,
The seal groove, which closes in the boss setting and the seal groove, is equipped with sealing ring；The left terminal pad, the right company
It connects and forms seal chamber between disk and the inner connection tube, sealing liquid is marked in the seal chamber；Further include and the seal chamber
Connection and the gas leakage sensing chamber being located on the upside of the seal chamber, the gas leakage detect indoor sliding and are equipped with push plate, the push plate
Upper end is equipped with gas leakage notice board, and the top of the gas leakage sensing chamber is equipped with for the gas leakage notice board through and out the gas leakage
The through-hole of sensing chamber.
The sealing ring is V-shaped seal ring as a preferred technical solution,.
The first flange and the second flange are respectively positioned in the seal chamber as a preferred technical solution,.
The upstream end of the inner connection tube is equipped with aeroscopic plate as a preferred technical solution, and the aeroscopic plate is in horn-like
And the small end of the aeroscopic plate is connected with the inner connection tube.
The flexible air bag of the outer sheath of the aeroscopic plate as a preferred technical solution, the elastic balloon and described leads
Between gas plate formed pressure seal room, the opening of the pressure seal room towards the aeroscopic plate far from the inner connection tube one
End.
Pressure valve is provided between the gas leakage sensing chamber and the seal chamber as a preferred technical solution,.
By adopting the above-described technical solution, natural gas line connection is interior with having the pipe jointer of leak detection function to pass through
Connecting tube and sealing ring and upstream line and downstream line formation interference fit on inner connection tube, are fixed on upstream line
In lower oil-piping.Natural gas gives the pressure that sealing ring is pushed into seal chamber, and liquid is marked in seal chamber to offset this
Pressure realizes better seal between inner connection tube and upstream line and downstream line.When there is slow gas leakage in sealing ring, gas
Sealed chamber enters gas leakage sensing chamber and will not leak, when the pressure of gas leakage sensing chamber is enough to overcome the resistance of push plate, gas leakage
Notice board is pushed out gas leakage sensing chamber, gives service personnel's prompt.
