Detailed Description

The following is a specific embodiment of the present invention, which will be further described with reference to the accompanying drawings.

Referring to fig. 1 and 2, the two sides of an annular flange II 6 of the quick claw coupling are respectively provided with an inner spigot. Casing II 7 is the cylinder, and the cooperation of casing II 7 left end is installed in II 6 right sides of ring flange inner front, and II 7 left ends of casing and II 6 right sides of ring flange welded fastening. Casing I5 is used for the suit to freeze on pipe 12, and the cooperation of casing I5 right-hand member is installed in the tang in II 6 left sides of ring flange, and casing I5 right-hand member and II 6 left sides welded fastening of ring flange. The tang has been seted up on 3 right sides of hoop, and the cooperation of the I5 left end of casing is installed in the tang in 3 right sides of hoop, and the I5 left end of casing and 3 right sides welded fastening of hoop.

When the annular flange I1 is installed, the sleeve flange is connected to the freezing pipe 12, and the flange I1 is located on the left side of the hoop 3. The ring-shaped notch that is used for installing O type circle 2 is seted up to ring flange I1 right flank, and 3 left ends of hoop have the counter bore that is used for installing

O type circle

2, and 3 left ends of hoop imbed in the ring-shaped notch of ring flange I1 right flank. The flange plate I1 and the flange plate II 6 are connected through the bolts 4, and the extrusion of the O-shaped ring 2 is ensured in the annular notch on the right side face of the flange plate I1 and the counter bore at the left end of the flange plate I1.

A pipe fitting III 13 is fixedly connected to the circumferential surface of the shell II 7; a blank cap 8 is fixed at the right end of the shell II 7, and a pipe II 11 is installed at the axis of the blank cap 8; the right end of the pipe fitting II 11 is connected with an elbow 9, and the other end of the elbow 9 is connected with a pipe fitting I10.

The embodiment changes rigid connection installation into flexible connection installation, and is convenient to disassemble and recover, can be repeatedly used, and reduces construction cost. The construction process is simple and convenient, the construction of electric welding and gas cutting on site is reduced, the site occupation is reduced, the risk of the construction site is avoided, no requirement is imposed on the construction type, the construction type requirement is reduced, and the labor cost is reduced; can be produced in factory, and has easy manufacture and low cost. When the quick coupler of the horn head is connected, the middle O-shaped ring extruded between the flange plate I1 and the flange plate I1 plays a role in sealing, and the pressure of a freezing pipe test is met through testing.
