Outer wall is taper at the both ends nozzle of bend pipe, the right end nozzle of outer wall shape and three-way body at the both ends nozzle of bend pipe
Place's inner wall shape matches.The second external screw thread is respectively equipped on outer wall at the both ends nozzle of bend pipe.
Stairstepping through-hole is equipped on attachment cap, the diameter in the left end hole of stairstepping through-hole is greater than the diameter in right end hole,
The left end inner wall of stairstepping through-hole is equipped with third internal screw thread.
The left end of bend pipe pass through attachment cap on stairstepping through-hole insertion three-way body right end nozzle in, the left end of bend pipe and
The right end nozzle of three-way body is threadedly coupled, in the left end hole of the stairstepping through-hole on the right end nozzle insertion attachment cap of three-way body simultaneously
And three-way body and attachment cap are threadedly coupled.
It is arranged with sealing rubber ring and plain cushion from left to right on bend pipe.Plain cushion be located at stairstepping through-hole right end hole inner wall and
Between non-threaded section of outer wall of bend pipe, sealing rubber ring be located at the right end nozzle of three-way body right end inner wall and bend pipe it is non-threaded
Between section outer wall.Attachment cap is screwed, sealing rubber ring is compressed by plain cushion and is sealed, a kind of gas meter, flow meter connection combination is constituted
It sets.
The advantage is that: reducing interface, it is not easy to reveal, improves the safety of fuel gas pipeline.Have that structure is simple simultaneously,
It is easy to operate, good seal performance, the high feature of construction efficiency.
