Abstract
The utility model relates to a pipe fitting connecting piece, particularly a new pipe fitting connecting piece with no need of tapping on the pipe fitting. In the utility model, a left and a right clamping sleeves are sheathed on the sealing ring in the gap of the pipe fitting connection; besides, by means of the extrusion for one side slant face of the left and the right clamping sleeves during the rotating time of a nut and a screw bolt, the sealing ring can bear the pressure in axial direction and radial direction to act sealing and connecting functions. The utility model has the advantages of simple structure, convenient operation, non tapping, and easiness for multitudinous industrial production; on the ground of the sizes of the pipe fitting, corresponding connecting components can be selected to seal and connect the pipe fitting.
Description
The utility model relates to a kind of pipe connecting component, particularly a kind of novel pipe fitting coupling that need not tapping on pipe fitting.
As will connecting to pipe fitting, must be on two pipe fittings external threading, can connect, need use tapping machine like this, and carry out tapping inconvenience especially being embedded in underground pipe fitting, let alone and carry out industrialization tapping in batch.
The purpose of this utility model will overcome above-mentioned defective exactly, designs the pipe fitting coupling that a kind of utmost point easily need not tapping.
The technical solution of the utility model is:
On the seal ring on the interface of left pipe fitting, the butt joint of right pipe fitting left cutting ferrule, the tight casing pressure of right cutting ferrule are arranged, outer nut and hollow bolt are connected with a joggle, and cover is pressed on left cutting ferrule, the right cutting ferrule.
Advantage of the present utility model and effect are and need not carry out tapping to pipe fitting, choose seal ring left side cutting ferrule, right cutting ferrule and outer nut, hollow bolt by pipe fitting corresponding size size, can connect pipe fitting, easy to use, simple, and be easy to industrialized mass production.
Accompanying drawing
Fig. 1--the utility model structural principle and use schematic representation.
Embodiment:
As shown in Figure 1, for left pipe fitting 6, right pipe fitting 7 needs to connect, can be with the outer nut 1 of corresponding size, left side cutting ferrule 2, seal ring 5 successively is set on the left pipe fitting 6, again with hollow bolt 4, right cutting ferrule 3, successively be set on the right pipe fitting 7, then with left pipe fitting 6, the interface of right pipe fitting 7 is alignment as far as possible, seal ring 5 is sealed space between the two pipe fittings, again with left cutting ferrule 2, right cutting ferrule 3 alignment bosses are pressed on the seal ring 5, outer nut 1 and hollow bolt 4 are rotatably connected, because the left side of left cutting ferrule 2 and right cutting ferrule 3, all there is an inclined-plane on the right side, when outer nut 1 and hollow bolt 4 screw and oppress the inclined-plane, left side cutting ferrule 2, right cutting ferrule 3 is axial and radially all stressed, make it tightly encase tube wall and crush seal circle 5, thereby the effect of playing sealing and connecting.
Claims (2)
1, novel pipe fitting coupling is characterized in that on the seal ring 5 on the interface of left pipe fitting 6, right pipe fitting 7 butt joints left cutting ferrule 2, right cutting ferrule 3 tight casing pressures being arranged, and outer nut 1 is connected with a joggle with hollow bolt 4, overlaps to be pressed on left cutting ferrule 2, the right cutting ferrule 3.
2, novel pipe fitting coupling according to claim 1 is characterized in that all there is an inclined-plane on left cutting ferrule 2 left sides, right cutting ferrule 3 right sides.
