Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further illustrated.
As shown in the figure, the utility model provides a kind of SEALING FITTING connecting Bamboo-shaped prestressed plastic pipe racks bolt-locking, described SEALING FITTING 5 is docked combination by a pair semi-circular tube 1 of the identical specular of structure and is formed, and will dock the fastening combination in mating face by bolt fastener group 4.
Two that the inner ring of described each semi-circular tube 1 all has structure same intervals to arrange large annular groove 1b, two little annular groove 1a and sealing gasket groove 1c; Described two large annular groove 1b are separately positioned on the both sides of each semi-circular tube 1 mid-length; Described two little annular groove 1a are separately positioned on the outside of two large annular groove 1b; A sealing gasket groove 1c is respectively arranged with in the both sides of each large annular groove 1b.
Described two large annular groove 1b are wrapped in the outer rim of the first large annular muscle 3b in Bamboo-shaped prestressed plastic pipe 3 end that SEALING FITTING 5 two ends connect respectively respectively; Described two little annular groove 1a are wrapped in the outer rim of the first little annular muscle 3a in Bamboo-shaped prestressed plastic pipe 3 end that SEALING FITTING 5 two ends connect respectively respectively; Described sealing gasket groove 1c is corresponding with the little straight tube 3c position of first large annular muscle 3b both sides, described Bamboo-shaped prestressed plastic pipe 3 end; In described sealing gasket groove 1c, sealing gasket 2 is housed respectively.
The fastening docking mating face of described bolt fastener group 4 is two pairs of flanged surfaces, and described two pairs of flanged surfaces are axially protruded to respective outer rim along SEALING FITTING 5 respectively by the mating face, both sides of each semi-circular tube 1 to be formed.
Described bolt fastener group 4, after bolt 4a passes the bolt hole 1d of a pair semi-circular tube 1, is fitted on bolt 4a, by the fastening combination of described flanged surface of a pair semi-circular tube 1 by nut 4b.
Transverse sealing connecting groove 1g junction plane being respectively arranged with and being communicated with described sealing gasket groove 1c is docked at described a pair semi-circular tube 1.
Described sealing gasket 2 comprises the longitudinal sealing pad 2a of multiple semicircles of vertical seal joint 5 axis and is parallel to SEALING FITTING 5 axially and be positioned at the lateral connection sealing gasket 2b at multiple longitudinal sealing pad 2a two ends; Described multiple longitudinal sealing pad 2a is separately positioned in the described sealing gasket groove 1c on described a pair semi-circular tube 1 inner ring; Described lateral connection sealing gasket 2b is separately positioned in the transverse sealing connecting groove 1g that described a pair semi-circular tube 1 dock on junction plane.
In particular, as shown in Figure 1 and Figure 2, two pairs of flanged surfaces that positional symmetry structure is identical at the docking junction plane of a pair semi-circular tube 1 both sides, each side flange face of each semi-circular tube 1 is provided with two bolt hole 1d, bolt hole 1d position on a pair two pairs, semi-circular tube 1 both sides flanged surface is corresponding, be convenient to bolt 4a pass, by the nut 4b being fitted in bolt 4a end, a pair semi-circular tube 1 be locked.
As shown in the figure, two large annular groove 1b that a pair semi-circular tube 1 inner ring is arranged respectively are used for wrapping up in the outer rim of the first large annular muscle 3b in Bamboo-shaped prestressed plastic pipe 3 end; Two little annular groove 1a that a pair semi-circular tube 1 inner ring is arranged respectively are wrapped in the outer rim of the first little annular muscle 3a in Bamboo-shaped prestressed plastic pipe 3 end that pipe SEALING FITTING 5 two ends connect respectively respectively.
