Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further illustrated.
As shown in Figure 1 and Figure 2, the utility model provides a kind of SEALING FITTING connecting Bamboo-shaped prestressed plastic pipe, and described SEALING FITTING 4 is relatively bonded with a pair semi-circular tube 1 docking of specular the SEALING FITTING 4 that cross section is circle by structure.
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 4 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 4 two ends connect respectively respectively; The little straight tube 3c position of all first with the described Bamboo-shaped prestressed plastic pipe 3 end large annular muscle 3b both sides of described sealing gasket groove 1c is corresponding; In described sealing gasket groove 1c, sealing gasket 2 is housed respectively.
The mating face that described a pair semi-circular tube 1 docks is flanged surface 1e, and this flanged surface 1e axially protrudes to respective outer rim the mating face formed by the mating face of a pair semi-circular tube 1 along SEALING FITTING 4.
Transverse sealing connecting groove 1d junction plane being provided with and being communicated with described sealing gasket groove 1c is docked at each semi-circular tube 1.
Described sealing gasket 2 comprises the longitudinal sealing pad 2a of multiple semicircles of vertical seal joint 4 axis and is parallel to the lateral connection sealing gasket 2b that SEALING FITTING 4 is axially positioned at multiple longitudinal sealing pad 2a two ends; Described multiple longitudinal sealing pad 2a is arranged in described sealing gasket groove 1c; Described lateral connection sealing gasket 2b is arranged in transverse sealing connecting groove 1d.
In particular, as depicted in figs. 1 and 2, semi-circular tube 1 has two, the relatively same specular of structure, the flanged surface 1c of specular two semi-circular tubes 1 presses close to engage, two semi-circular tubes 1 can adopt sealing gluing and is connected, bolt-locking connection or adhesive tape bundle and be connected to form a pipe SEALING FITTING 4.
As shown in Figure 1, Figure 3, semi-circular tube 1 inner ring is provided with two large annular groove 1b, two large annular groove 1b are used in the outer rim of the first large annular muscle 3b in two Bamboo-shaped prestressed plastic pipe 3 ends wrapping up pre-connection.
Described two little annular groove 1a wrap up in the outer rim of the first little annular muscle 3a in two Bamboo-shaped prestressed plastic pipe 3 ends of pre-connection respectively.
Sealing gasket groove 1c is had respectively at semi-circular tube 1 inner ring of each large annular groove 1b left and right sides, in sealing gasket groove 1c, semicircular sealing gasket 2 is installed, sealing gasket 2 is connected as a single entity by multiple longitudinal sealing pad 2a and two lateral connection sealing gasket 2b, is put into respectively in described sealing gasket groove 1c and transverse sealing connecting groove 1d.The degree of depth of the Thickness Ratio sealing gasket groove 1c of sealing gasket 2 is large, from the projecting inward part of sealing gasket groove 1c after installation, because sealing gasket 2 adopts rubber or other elastic material to make, when two semi-circular tubes 1 compress, on the sealing gasket 2 little straight tube 3c being wrapped in first large annular muscle 3b both sides, Bamboo-shaped prestressed plastic pipe 3 end tightly, thus play seal action.
As shown in Figure 1, in use, the Bamboo-shaped prestressed plastic pipe 3 connected is needed to align placement at SEALING FITTING 4 two ends, then the semi-circular tube 1 two being equipped with sealing gasket 2 is enclosed within Bamboo-shaped prestressed plastic pipe 3 end respectively, clamping two halves pipe 1, under the pressuring action of sealing gasket 2, be easy to realize vacuum seal and connect.
