Abstract
A steel pipe joint with a clamping sleeve comprises a hollow joint body and a nut, wherein a pipe penetrates through the hollow part of the joint body and the nut, a clamping sleeve is arranged between the pipe and the joint body as well as between the pipe and the nut, the lower end of the nut is provided with a mounting groove, the clamping sleeve comprises a front clamping sleeve and a rear clamping sleeve, the front clamping sleeve is pushed into the joint body and the clamping sleeve to form a main seal, the rear clamping sleeve inwards generates a hinge action to strongly grip the clamping sleeve, the geometric shape of the rear clamping sleeve is beneficial to generating an advanced engineering hinge clamping action, the action can convert axial movement into a radial extrusion action on the clamping sleeve, and only small assembling torque is needed during operation.
Description
Technical Field
The utility model relates to a clamping sleeve steel pipe joint.
Background
In car, boats and ships and engineering equipment, there are the connection of many oil pipes and trachea, adopt a hollow joint body and a nut mostly, the pipe is worn to put in the cavity department that connects body and nut, still be equipped with a cutting ferrule between pipe and joint body, the nut, can make the cutting ferrule warp when screwing the nut, thereby play fixed and sealed effect, but this kind of cutting ferrule need be setting up the sealing washer, seal through sealing washer and cutting ferrule, thereby the sealing washer is ageing or melt when high temperature easily and lead to the phenomenon of revealing.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical insufficiency, the utility model provides a clamping sleeve steel pipe joint.
The utility model provides a clamping sleeve steel pipe joint, which comprises a hollow joint body and a nut, wherein a pipe penetrates through the hollow parts of the joint body and the nut, a clamping sleeve is arranged between the pipe and the joint body as well as between the pipe and the nut, the lower end of the nut is provided with a mounting groove, the clamping sleeve comprises a front clamping sleeve and a rear clamping sleeve, the lower end of the front clamping sleeve is provided with a conical surface, and the upper end of the front clamping sleeve is provided with a chamfer surface; the cross section of the rear clamping sleeve is T-shaped, a chamfer surface is arranged at the lower end of the rear clamping sleeve, a first annular groove is formed in the inner top wall of the mounting groove, a plurality of balls are slidably connected inside the first annular groove, a second annular groove matched with the first annular groove is formed in the upper end of the rear clamping sleeve, the upper end of the front clamping sleeve is in extrusion fit with the lower end of the rear clamping sleeve, the inner wall of the connector body is a conical surface, and the lower end of the front clamping sleeve is in extrusion fit with the inner wall of the connector body.
The front cutting ferrule and the rear cutting ferrule both have elasticity.
The upper end of the nut is provided with an integrally formed protective sleeve.
The joint body stainless steel structure.
The nut is a stainless steel structure.
Has the advantages that:
the front ferrule is pushed into the connector body and ferrule tube to form a primary seal, while the rear ferrule creates a hinging action inward to form a strong grip on the ferrule tube, and the rear ferrule geometry helps create an advanced engineered hinging ferrule action that translates axial movement into a radial squeeze on the ferrule tube requiring only a small assembly torque during operation.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an enlarged view of a portion a.
FIG. 3 is an enlarged view of the portion B.
The connector comprises a connector body 1, a nut 2, a front clamping sleeve 3, a rear clamping sleeve 4, a mounting groove 5, a protective sleeve 6, a second annular groove 7 and a ball 8.
Detailed Description
The embodiments of the present invention will be further explained with reference to the accompanying drawings:
a sleeve steel pipe joint comprises a hollow joint body 1 and a nut 2, wherein a pipe penetrates through the hollow part of the joint body 1 and the nut 2, a sleeve is arranged between the pipe and the joint body 1 and between the pipe and the nut 2, the lower end of the nut 2 is provided with a mounting groove 5, the sleeve comprises a front sleeve 3 and a rear sleeve 4, the lower end of the front sleeve 3 is provided with a conical surface, and the upper end of the front sleeve is provided with a chamfered surface; the cross section of the rear cutting sleeve 4 is T-shaped, the lower end of the rear cutting sleeve 4 is provided with a chamfer surface, a first annular groove is formed in the inner top wall of the mounting groove 5, a plurality of balls 8 are slidably connected inside the first annular groove, a second annular groove 7 matched with the first annular groove is formed in the upper end of the rear cutting sleeve 4, the upper end of the front cutting sleeve 3 is in extrusion fit with the lower end of the rear cutting sleeve 4, the inner wall of the connector body 1 is a conical surface, and the lower end of the front cutting sleeve 3 is in extrusion fit with the inner wall of the connector body 1.
The front ferrule 3 is pushed into the body 1 and forms a primary seal with the ferrule, while the rear ferrule 4 is hinged inwardly to provide a strong grip on the ferrule, and the geometry of the rear ferrule 4 helps to provide an advanced engineered hinged ferrule action that translates axial movement into radial compression on the ferrule, requiring only a small assembly torque during operation.
Because ball in cutting ferrule nut 2 makes nut 2 and back cutting ferrule 4 take place rolling friction to the revolving force that back cutting ferrule 4 received has effectively been reduced, thereby makes back cutting ferrule 4 irrotational, thereby has avoided the wearing and tearing that back cutting ferrule 4 and the rotatory bring of preceding cutting ferrule 3, thereby has protected nut 2, back cutting ferrule 4, preceding sleeve pipe and joint body 1, thereby has prolonged double-jaw union's life.
The front cutting ferrule 3 and the rear cutting ferrule 4 both have elasticity.
