Abstract
The utility model provides a quick coupler, which comprises a shell, wherein the shell is a semicircular metal body; two coupler keys are arranged on the bottom surface of the shell; the coupler keys are arranged on the bottom surface of the shell along a longitudinal direction of the shell; and two ends of the shell are provided with connecting parts. The quick coupler can be installed in a direct sleeving way without dismounting a part, such as a bolt and a nut, a seal ring and the like, so that the loss of the part, such as the bolt, the nut and the like, can be avoided in the process of installation, and the coupler is conveniently reused, for example, the coupler can be reused for an underground pipe installation of a coal mine.
Description
Technical field
The utility model relates to the pipe fittings technical field, particularly a kind of ready-package joint.
Background technique
The groove type joint that existing technology provides needs demounting bolt nut and seal ring in installation, seal ring, shell and bolt and nut are installed then successively, and installation process is more, and in installation, loses parts such as bolt and nut easily.
The model utility content
The utility model provides a kind of ready-package joint, and directly sleeve type is installed, and avoids in installation, losing parts such as bolt and nut.
To achieve these goals, the utility model provides following technological scheme:
A kind of ready-package joint; It comprises: housing, said housing are semicircular metal body, and the bottom surface of said housing is provided with two joint keys; Said joint key is arranged on the bottom surface of said housing along the longitudinal direction of said housing, and the two ends of said housing are provided with joint.
Preferably, said joint is provided with screw, is equiped with bolt on the said screw, and the head end of said bolt is equiped with nut.
Preferably, the bottom surface of said housing also is lined with seal ring.
Preferably, the inner chamber of said housing is provided with and is used for the space that said seal ring is unfolded.
Preferably, the bolt block of said joint is a ramp structure.
Through implementing above technological scheme; Has following technique effect: the ready-package joint that the utility model provides; Need not demounting bolt nut and seals and other component, directly sleeve type is installed, and avoids in installation, losing parts such as bolt and nut; And make things convenient for the repeated use of joint, like the piping erection under the coal mine in repeated use.
Description of drawings
The structural representation of the housing that Fig. 1 provides for the utility model;
The structural representation of the ready-package joint that Fig. 2 provides for the utility model;
The application schematic representation of the ready-package joint that Fig. 3 provides for the utility model.
Embodiment
In order better to understand the technological scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of ready-package joint; Like Fig. 1, Fig. 2 and shown in Figure 3; Comprise: housing 101, said housing 101 is semicircular metal body, the bottom surface of said housing 101 is provided with two joint keys; Said joint key is arranged on the bottom surface of said housing 101 along the longitudinal direction of said housing 101, and the two ends of said housing 101 are provided with joint 104.
In the above-described embodiments, concrete, said joint 104 is provided with screw 105, is equiped with bolt on the said screw, and the head end of said bolt is equiped with nut 103.
In other embodiment, on the foregoing description basis, further, the bottom surface of said housing 101 also is lined with seal ring 102.The seal ring that the foregoing description provides is realized triple seal, and is specific as follows:
First resealing:
Owing to be the ready-package joint, the base angle somewhat larger in diameter of seal ring is in outer diameter tube, and the drift angle internal diameter of the sealing lip of broadening formation is less than outer diameter tube; When being installed to pipe surface (A size area), the sealing lip drift angle internal diameter of seal ring enlarges slightly, because the elasticity of rubber; Make the seal ring tensioner in pipe surface; To pipe surface a part of impacting force is provided through sealing lip, thereby realizes first resealing of G06 " E " type sealing principle, i.e. " O " type circle sealing mechanism.
Second resealing:
Because the Seal cage internal diameter of joint shell and seal ring external diameter coupling; In installation process, fastening through bolt makes seal ring slowly be adjacent to pipe surface and gradually reduces; Be in place (metal to metal) until shell, at this moment seal ring also all compresses and puts in place.Seal ring reduces owing to compression makes highly, because the elasticity of rubber makes seal ring be pressed in pipe surface, to pipe surface impacting force is provided through sealing lip once more, thereby realizes second resealing of G06 " E " type sealing principle, i.e. gasket type sealing mechanism.
Triple seal:
Also pressurize when pipe interior is full of medium, according to hydromechanical principle, the pressure of medium acts on the surface of internal cavity of seal ring uniformly, and and Surface Vertical.The pressure of medium is applied to pipe surface once more through sealing lip, and affacts pipe surface, thereby forms triple seal, i.e. the reaction equation sealing mechanism.
In other embodiment, on the foregoing description basis, further, the inner chamber of said housing is provided with and is used for the space that said seal ring is unfolded.The expansion of internal diameter of the seal ring; Possibly cause the decline of sealability; Therefore, Seal cage volume enough again in the housing compresses seal is guaranteed in this space, and its objective is to increase the radial compression of seal ring amount; Guarantee that seal ring has enough radial compression forces after installation, reach the effect of superior sealing.
In other embodiment; On the foregoing description basis; Preferably, do not produce excessive pretightening force (be embodied in and be mounting torque on the bolt) when for the ease of joint (process of clamping bolt) being installed, the bolt block of said joint 104 is a ramp structure; Add the pretightening force of king-bolt through the inclined-plane, finally guarantee light erection joint.
This ready-package joint has increased the seal angle of sealing lip; (conventional joint when mounted need be through the people for adding the tensile seal ring to make pipeline 110 can easily be inserted into seal ring; Because the base angle internal diameter of seal ring is less than outer diameter tube; So need to be inserted in separately earlier seal ring when mounted), the seal angle that adds wide-angle simultaneously plays the pretension and the positioning action of seal ring 102.The joint key of this ready-package joint and the groove bottom land of pipeline 110 leave certain clearance, to realize the functions such as axial displacement, angular deflection and rotation of this ready-package joint on pipeline.
More than a kind of ready-package joint that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.
