Description

Socket type quick installation hose assembly

technical field

The utility model relates to a fluid conveying device, in particular to a socket-type fast-loading hose assembly.

Background technique

The hose assembly is used as a delivery pipeline for various gases and liquids in the fluid delivery system, and is widely used in industry and life. It is made of high-pressure steel wire braided or wound rubber hose and steel joints crimped by special equipment, used for hydraulic power transmission or transport of water, gas, oil and other pressure media to ensure the circulation of liquid and the transmission of liquid energy. At present, most of the joints at both ends of the existing hose assembly are flanges or threaded connections, and the sealing effect is achieved by fastening the end face or the tapered surface and the sealing member through bolts or nuts. This installation and disassembly of the seal and the connecting bolt is not only cumbersome, but also takes a long time to operate, and it is easy to lose after disassembly. In addition, its tightness is greatly affected by human operation.

Contents of the invention

In order to solve the deficiencies of the prior art, the purpose of the utility model is to provide a socket-type fast-installation hose assembly with convenient operation, fast connection and good sealing performance.

The technical solution adopted to achieve the purpose of this utility model is: the socket-type quick-install hose assembly includes a socket joint, a socket joint, an external bushing, an internal bushing, a hose, a sealing ring, a sponge strip, an elastic snap ring; both ends of the hose are fixed with steel joints, one end is a socket joint and the other end is a socket joint; the middle part of the outer circle of the socket joint has an R-shaped outer circle for positioning the elastic snap ring Arc groove, the socket joint is far away from the socket end and welded with a socket external bushing, the socket external bushing is clamped and fixed by the socket internal bushing and a hose is fixed; the two rectangular grooves inside the socket joint are respectively installed with seals Ring and sponge strip, and an elastic snap ring is installed in an R-shaped inner arc groove. The socket joint is far away from the socket end and welded with a socket external bushing. Fasten the hose tightly.

Before connecting the hoses, first put the sealing ring, sponge strip, and elastic snap ring into the annular groove inside the socket joint, so that they do not need to be disassembled when used again; when connecting the hoses, just put the The socket end is docked with the socket end, and the two joints are inserted into place with a special tool, so that the elastic snap ring snaps into the R-shaped arc groove outside the socket joint to realize the pipeline connection and sealing function.

The advantages of the utility model socket-type fast-installation hose assembly are: the hose and the hose are quickly connected, the sealing performance is good, the pressure is high, the operation is convenient, the maneuverability is high, and it can be used repeatedly, and it can meet the temporary And long-distance pipeline construction, as well as complex terrain pipeline laying and other requirements, the transmission working pressure can reach 6MPa

Detailed ways

In the accompanying drawings, the socket-type quick-install hose assembly of the utility model includes a socket joint, a socket joint, an external bushing, an internal bushing, a hose, a sealing ring, a sponge strip, and an elastic snap ring; Both ends of the hose 4 are fixed with steel joints, one end is a socket joint 1, and the other end is a socket joint 7; Arc groove, the socket joint is far away from the socket end and welded with socket external bushing 2, the socket external bushing 2 is clamped and fixed by the socket internal bushing 3, and the hose 4 is fixed; the socket joint 7 has two rectangular grooves inside A sealing ring 8 and a sponge strip 9 are respectively installed in the groove, and an elastic snap ring 10 is also installed in an R-shaped inner arc groove. The outer bushing 5 is clamped and fixed with the flexible pipe 4 by the inner bushing 6 of the socket.

The socket joint 1 is an inner joint, and the end of the joint is arc-shaped. There is a tapered surface at the front end of the outer surface for contacting with the sealing ring 8 to achieve sealing. The rear half has a circle of square bosses for positioning and disassembly. tool. The socket joint 7 belongs to an external joint, and a circle of square grooves is arranged on the outer circle of the joint to be used for positioning dismounting tool. The outer diameter of socket external bushing 2 and socket external bushing 5 has a section of external thread and a section of sawtooth shape, and the end is arc-shaped; the inner side of socket internal bushing 3 and socket internal bushing 6 has a section of internal thread and a section of Jagged.
