Embodiment
The exemplary embodiment embodying the utility model feature & benefits will describe in the following description in detail. Iting should be understood that the utility model can have various changes in different enforcement modes, it does not all depart from scope of the present utility model, and explanation wherein and to be shown in be use when explain in essence, and is not used to restriction the utility model.
Consulting Fig. 1 and Fig. 2, the piping system sealing connection (hereinafter referred to as " sealing connection ") of the present embodiment mainly comprises adapter piece 1, jointed tubular workpieces 2, live cover nut 3 and card core 4. Wherein, adapter piece 1 and jointed tubular workpieces 2 are formed by cover nut 3 of living and are removably connected, and card core 4 is arranged at the junction of adapter piece 1 with jointed tubular workpieces 2, reaches the effect of sealing.
Consult Fig. 2 and Fig. 3, adapter piece 1 one end is provided with the pipeline connection section 11 for connecting exterior line parts, the other end inside is provided with the joint hole 12 for stretching into for jointed tubular workpieces 2, being provided with enlarging 14 from joint this end end of 12 to adapter piece 1, hole, this end of adapter piece 1 is also provided with outside screw 13 to coordinate with cover nut 3 of living.
Jointed tubular workpieces 2 one end is provided with the pipeline connection section 22 for connecting exterior line parts, and the other end is provided with the coupling section 21 for coordinating with adapter piece 1, and this coupling section 21 is adaptive with the joint hole 12 of adapter piece 1; Having one between pipeline connection section 22 and coupling section 21 can the holding boss 23 overlapping nut 3 alive.
As shown in Figure 2, the coupling section 21 of jointed tubular workpieces 2 passes the enlarging 14 of adapter piece 1 and stretches into and engage in hole 12, and the outer wall of coupling section 21 is generally fitted with the inwall engaging hole 12.Having gap between coupling section 21 and enlarging 14, card core 4 is sheathed on coupling section 21 and fills the gap between coupling section 21 and enlarging 14.
Cover nut 3 of living is sheathed on jointed tubular workpieces 2 from pipeline connection section 22 one end of jointed tubular workpieces 2, and by boss 23 axial limiting, then it is connected cooperation with the outside screw 13 of adapter piece 1, thus adapter piece 1 is connected fastening with jointed tubular workpieces 2.
The length engaging coupling section 21 on the degree of depth (length) in hole 12 and jointed tubular workpieces 2 in adapter piece 1 is arranged according to actual needs, and in the present embodiment, engaging hole 12 is cylindrical hole, and its aperture is definite value along its depth direction; Correspondingly, coupling section 21 is straight length, and its external diameter is also constant along its length.
