Abstract
Double-deck sound-proof drain pipe connection fittings, comprise and connect body (1), on the inwall of connection body (1), form annular U type slot (2), double-deck sound insulation tube (A) sleeve is in annular U type slot (2), and the top layer of double-deck sound insulation tube (A) the pipe outer wall of (A1) and the inwall of nexine pipe (A2) bond together by glue with the external annulus (21) and the internal ring wall (22) that form annular U type slot (2) respectively.It can closely couple together double-deck sound-proof drain pipe and PVC groove pipe fitting, simultaneously by the grate opening port sealing of double-deck sound-proof drain pipe, allows double-deck sound-proof drain pipe really play the function of noise reduction.
Description
Technical field:
The utility model relates to groove pipe fitting technical field, more specifically to a kind of groove pipe fitting connecting for double-deck sound-proof drain pipe.
Background technique:
As shown in Figure 1, there is on the market at present a kind of double-deck sound-proof drain pipe A, it by top layer, manages A1, nexine pipe A2 and grid sheet A3 forms, shape grate opening A4 between top layer pipe A1, nexine pipe A2 and grid sheet A3, the excessive problem of current noise when it has solved common hard polvinyl choride pipe draining, according to Tongji University's acoustic investigation test, double-deck sound-proof drain pipe can reduce about 16DB (A) than the common hard polvinyl choride pipe will of making an uproar, sound-deadening and noise-reducing effect is fairly obvious.Its deficiency is: the tube wall of double-deck sound-proof drain pipe approaches two times of left and right of common PVC-U waste pipe thickness, cannot solve the problem that connects and seal while connecting with common PVC groove pipe fitting simultaneously.This is because double-deck sound-proof drain pipe exists grate opening A4, not too easy of the face seal of this grate opening A4 on common groove pipe fitting, someone adopts packing ring to seal grate opening A4, but still there is the situation of grate opening A4 water inlet or air, in grate opening A4, once entered mobile water or air, double-deck sound-proof drain pipe cannot play the function of noise reduction.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provide a kind of double-deck sound-proof drain pipe connection fittings, it can closely couple together double-deck sound-proof drain pipe and PVC groove pipe fitting, by the grate opening port sealing of double-deck sound-proof drain pipe, allow double-deck sound-proof drain pipe really play the function of noise reduction simultaneously.
Technology solution of the present utility model is as follows:
Double-deck sound-proof drain pipe connection fittings, comprise connection body, on the inwall of connection body, form annular U type slot, double-deck sound insulation tube sleeve is in annular U type slot, and the outer wall of the top layer pipe of double-deck sound insulation tube and the inwall of nexine pipe bond together by glue with the external annulus and the internal ring wall that form annular U type slot respectively.
Described connection body is straight tube, on two end inwalls of connection body, all forms annular U type slot.
Described connection body is swan neck, on two end inwalls of connection body, all forms annular U type slot.
Described connection body is three-way pipe, and on the inwall of connection body, each threeway opening all forms annular U type slot.
Described connection body is big or small head tube, and on the inwall of connection body, each CONCENTRIC REDUCER opening all forms annular U type slot.
The beneficial effects of the utility model are:
It can closely couple together double-deck sound-proof drain pipe and PVC groove pipe fitting, simultaneously by the grate opening port sealing of double-deck sound-proof drain pipe, allows double-deck sound-proof drain pipe really play the function of noise reduction.
Accompanying drawing explanation:
Fig. 1 is the structural representation of double-deck sound-proof drain pipe;
Fig. 2 connects the structural representation of body in embodiment 1;
Fig. 3 is embodiment 1 structural representation;
Fig. 4 is embodiment 2 structural representation;
Fig. 5 is embodiment 3 structural representation;

In figure: A, double-deck sound-proof drain pipe; A1, top layer pipe; A2, nexine pipe; A3, grid sheet; A4, grate opening; 1, connect body; 2, annular U type slot; 21, external annulus; 22, internal ring wall.
Embodiment:
Embodiment 1: see shown in Fig. 1 to 3, double-deck sound-proof drain pipe connection fittings, comprise and connect body 1, on the inwall of connection body 1, form annular U type slot 2, double-deck sound insulation tube A sleeve is in annular U type slot 2, and the top layer of the double-deck sound insulation tube A pipe outer wall of A1 and the inwall of nexine pipe A2 bond together by glue with the external annulus 21 and the internal ring wall 22 that form annular U type slot 2 respectively.The present embodiment is equivalent to double-deck sound-proof drain pipe to make common PVC waste pipe, by annular U type slot 2, grate opening A4 has been sealed to water simultaneously.
Embodiment 2, and as shown in Figure 4, described connection body 1 is straight tube, on two end inwalls of connection body 1, all form annular U type slot 2.All the other are with embodiment 1, and the present embodiment is the straight-through connection pipe fitting of double-deck sound-proof drain pipe.
Embodiment 3, and as shown in Figure 5, described connection body 1 is swan neck, on two end inwalls of connection body 1, all form annular U type slot 2.All the other are with embodiment 1, and the present embodiment is double-deck sound-proof drain pipe elbow connection pipe fitting.
Embodiment 4, and as shown in Figure 6, described connection body 1 is three-way pipe, and on the inwall of connection body 1, each threeway opening all forms annular U type slot 2.All the other are with embodiment 1, and the present embodiment is double-deck sound-proof drain pipe three-limb tube part.
Embodiment 5, and as shown in Figure 7, described connection body 1 is big or small head tube, and on the inwall of connection body 1, each CONCENTRIC REDUCER opening all forms annular U type slot 2.All the other are with embodiment 1, and the present embodiment is double-deck sound-proof drain pipe CONCENTRIC REDUCER connection pipe fitting.
Working principle: the top layer pipe outer wall of A1 and the inwall of nexine pipe A2 of double-deck sound insulation tube A bond together by glue with the external annulus 21 and the internal ring wall 22 that form annular U type slot 2 respectively, so the grate opening A4 of double-deck sound insulation tube A is sealed by annular U type slot 2 and sealed, in drainage procedure, the water that grate opening A4 does not have gas flows through, and guarantees so the decrease of noise functions of double-deck sound insulation tube A.
