Topic, design is simple, rational in infrastructure, it is more solid and reliable by the connector connection of the present invention between two pipelines to connect.
Employed technical scheme comprise that
A kind of conduit coupling, including sleeve, upper press cover, lower cover it is characterised in that：
Sleeve is vertically arranged, and sleeve is hollow circular cylinder, and sleeve upper end outer wall is provided with external screw thread, and sleeve lower end outer wall sets
There is lower external screw thread, sleeve upper end inwall offers circular arc upper groove, and sleeve lower end inner wall offers circular arc low groove, circular arc
It is equiped with sealing gasket, upper sealing gasket lateral wall is circular arc, the inwall of circular arc upper groove and upper sealing gasket in shape upper groove
Lateral wall be fitted close, be equiped with lower seal pad in circular arc low groove, lower seal pad lateral wall be circular arc, under circular arc
The inwall of groove is fitted close with the lateral wall of lower seal pad, and upper press cover upper end offers upper conical hole, upper press cover lower end inner wall
It is provided with female thread, lower cover lower end offers inferior pyramidal hole, lower cover upper end inwall is provided with lower female thread, sleeve upper end outer wall
Threaded with upper press cover lower end inner wall, sleeve lower end outer wall is connected with lower cover upper end inner thread, in upper press cover and sleeve
The upper spring pad of installing in cavity between upper surface, upper spring pad upper end outer wall is provided with ramp, ramp and upper conical in the hole
Wall is fitted close, and upper spring pad inwall is provided with the first female thread, and the cavity between lower cover and sleeve lower surface is built-in to be set
Spring pad, lower spring pad lower end outer wall is provided with lower inclined plane, and lower inclined plane is fitted close with the inwall in inferior pyramidal hole, lower spring pad inwall
It is provided with the second female thread, be provided with upper gasket between upper spring pad and upper sealing gasket, set between lower spring pad and lower seal pad
There is lower gasket.
Advantage of the present utility model:
For pipe fitting, caducous situation is installed, spring pad is increased on pipe fitting, improve coating steel pipe outer wall and pipe fitting
Gmatjpdumamicss, by test, bear towing tension up to 20KN；Solve the caducous problem of appearance.Transformation centring ring and close on pipe fitting
Seal, rubber seal is arranged in groove, solves pipe fitting installation and the sealing that offset error also can guarantee that high pressure
Effect.Improved connector pipe fitting is easy to install, firm, safety.
Brief description
