Detailed Description

As shown in fig. 1, a composite pipe, including the articulated pipeline main part of constituteing of two closing plates 6, two closing plates 6 all form an arc convex part 4 with the opposite face of one side, the equal fixed mounting expansion pipe 2 of the opposite face of adjacent arc convex part 4, sealing contact mutually between two adjacent expansion pipes 2, form the first discharge passage 13 of a triangle-shaped form between two expansion pipes 2 and two closing plates 6, expansion pipe 2 is inside all to be provided with the second discharge passage 3 of an independent emission, the fluid material of different grade type is through first, the categorised emission of second discharge passage, the outside parcel tegument 1 of two closing plates 6.

As shown in fig. 2, a closed installation cavity is arranged inside the outer layer 1, the pipeline main body is installed in the installation cavity in a sealing manner, the outer layer 1 is made of hard PVC material, a first through hole 21 is arranged on the front end surface and the rear end surface of the outer layer, which face the first discharge channel 13, a corresponding second through hole 23 is arranged on the position facing the expansion pipe 2, the outer part of the expansion pipe 2 penetrates through the second through hole 23, the outer wall of the expansion pipe 2 is fixedly bonded with the inner wall of the second through hole 23 through glue, a discharge pipe (not shown) is introduced into the first through hole 21, and the discharge pipe penetrates through the first through hole 21 and extends into the first discharge channel 13.

Wherein, tegument 1 adopts two semicircular shell structures, and its both sides are provided with engaging lug 22 respectively, and through locking more than one screw fixation between the upper and lower engaging lug 22, the opposite face of engaging lug all imbeds and sets up one deck waterproof sealing layer, and the accessible is dismantled the screw on the engaging lug and is opened two teguments, realizes the operation to the inner pipe.

In this embodiment, the equal sealed one deck isolation layer 11 of packing into in the position that first discharge passageway is close to middle axis of rotation, the both sides of this isolation layer 11 are embedded into respectively in the draw-in groove of closing plate inner wall and are beaten waterproof glue bonding fixed, isolation layer 11 adopts elastic rubber material, isolation layer 11's effect prevents that the fluid material from flowing towards articulated department, and simultaneously, owing to be hinge structure, consequently two closing plates are being strutted the back, first discharge passageway can the grow, the isolation layer also can be followed tensile, satisfy the deformation demand.

In this embodiment, a contact end surface 61 is formed on the front and rear surfaces of the sealing plate 6, the contact end surface 61 is a plane, and is in sealing contact with the inner wall surfaces of the front and rear end surfaces of the outer tegument 1, a silica gel layer is bonded on each of the contact end surfaces of the sealing plate 6, and is in sealing contact with the inner wall surfaces of the front and rear end surfaces of the outer tegument through the silica gel layer, and the front and rear end surfaces of the whole pipeline main body are prevented from being in sealing contact with the two sides of the outer tegument through the silica gel layer, so that the two sides of the pipeline main body can be sealed, both sides of fluid materials.
