Abstract
The utility model provides a pipe interface, relating to the technical field of an interface. The pipe interface comprises an outer casing and an inner casing which is matched with the outer casing. The outer end of the inner casing is provided with an external screw thread, and the inner wall of the outer casing is provided with a groove; a sealing ring is arranged in the groove, the inner end of the inner casing is inserted into the outer casing, and the end of the outer casing and the central part of the inner casing are provided with corresponding clamping flanges; the cross-section of each clamping flange has a trapezoidal shape with a small upper end and a big lower end; a sealing ring is provided between the flange of the outer casing and the clamping flange of the inner casing; the flange of the inner casing and the flange of the outer casing are tightly clamped together by a clamping hoop, and the outer casing and the inner casing are tightly pressed together thereby. The pipe interface has the advantages of fast installation and good sealing performance.
Description
Affiliated technical field
The utility model relates to a kind of interface, especially a kind of pipe joint.
Background technique
In the prior art, when carrying liquid, the pipe joint of using adopts usually and is threaded, and installation rate is slow, and when pressure is high, occurs the phenomenon of leakage easily, uses safety inadequately, easily befouling environment.
Summary of the invention
Slow in order to overcome existing pipe joint installation rate, the deficiency of leakage appears easily, and the utility model provides a kind of pipe joint, and this pipe joint installation rate is fast, good seal performance.
The technological scheme that its technical problem that solves the utility model adopts is, a kind of pipe joint, comprise overcoat and the interior cover that is complementary, the outer end of interior cover is provided with outside thread, outer casing inner wall is provided with groove, be provided with seal ring in the groove, insert in the overcoat the inner of interior cover, overcoat end and interior cover middle part are provided with corresponding folder and embrace flange, the cross section that described folder is embraced flange is the trapezoidal shape that the upper end is little, the lower end is big, the folder of overcoat and interior cover is embraced and is provided with seal ring between the flange, thereby clamp clamps the flange of interior cover and overcoat overcoat and interior cover are compressed.
Described clamp is made up of two semi-round ring shape clamp parts, and two semi-round ring shape clamp parts are connected through the hinge together, and the outer end of two semi-round ring shape clamp parts is provided with screw, and screw rod and nut are housed on the screw.
Because this pipe joint comprises overcoat and the interior cover that is complementary, the outer end of interior cover is provided with outside thread, outer casing inner wall is provided with groove, be provided with seal ring in the groove, insert in the overcoat the inner of interior cover, and overcoat end and interior cover middle part are provided with corresponding folder and embrace flange, the cross section that described folder is embraced flange is the trapezoidal shape that the upper end is little, the lower end is big, the folder of overcoat and interior cover is embraced and is provided with seal ring between the flange, and clamp clamps the flange of interior cover and overcoat, thereby overcoat and interior cover are compressed.During use,, clamp with clamp again as long as overcoat and interior cover are plugged together, with regard to installation, so this pipe joint installation rate is fast, good seal performance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the long splice composition of embodiment's pipe joint.
Fig. 2 is the right elevation of Fig. 1.
Embodiment
As shown in Figure 1, a kind of pipe joint, comprise overcoat 1 and the interior cover 4 that is complementary, the outer end of interior cover 4 is provided with outside thread, overcoat 1 inwall is provided with groove 2, be provided with seal ring in the groove 2, insert in the overcoat 1 the inner of interior cover 4, overcoat 1 end and interior cover 4 middle parts are provided with corresponding folder and embrace flange 3, the cross section that described folder is embraced flange 3 is the trapezoidal shape that the upper end is little, the lower end is big, the folder of overcoat 1 and interior cover 4 is embraced and is provided with 5, one clamps 6 of seal ring between the flange 3 and the folder of interior cover and overcoat is embraced flange 3 clamps, thereby overcoat 1 and interior cover 4 are compressed.Described clamp 6 is made up of two semi-round ring shape clamp parts, the inner of two semi-round ring shape clamp parts links together by hinge 8, the outer end of two semi-round ring shape clamp parts all is provided with screw, and screw rod 7 and nut 9 are housed on the screw, clamp 6 can be compressed by screwing screw rod 7 and nut 9.During use,, with clamp 6 two folders are embraced flange 3 again and clamp, thereby overcoat 1 and interior cover 4 are compressed as long as overcoat 1 and interior cover 4 are plugged together, with regard to installation, so this pipe joint installation rate is fast, good seal performance.
