As preferably, inner and outer tubes are pegged graft and are also passed through glue sealing.Inner and outer tubes are located by positioning strip and locating slot and are strengthened sealing effectiveness by glue.
As preferably, described department of assembly comprises assembling pipe, screwed pipe, sealing ring, seal connector and locking blind nut, screwed pipe is fixedly connected with the assembling pipe, the assembling pipe is fixedly connected with connecting portion, screwed pipe and assembling pipe junction inwall are provided with step, screwed pipe and assembling pipe junction outer wall are provided with limited location snap ring, sealing ring, seal connector and locking blind nut all match with screwed pipe, sealing ring is positioned on the step, seal connector is positioned on the sealing ring, locking screw covers and is provided with the hole that matches with screwed pipe, and the locking blind nut is threaded with screwed pipe.It is that sealing ring can seal the junction for the ease of placement sealing ring and seal connector that screwed pipe and assembling pipe junction inwall are provided with step, and seal connector compresses sealing ring on the one hand, on the other hand external tubing is clamped.The locking blind nut is with sealing ring and seal connector locking.
As preferably, seal connector is two close-fitting connectors.After seal connector is divided into two, can better increase the sealing locking effect.
As preferably, described locking screw cover outer wall is provided with anti-skidding raised line.Anti-skidding raised line can so that locking screw lid screw installation.
As preferably, described tube connector and vertical direction angulation are ~ spend.Angle is to circulate between gutter and stack for the ease of air, prevents that the water in the gutter from flowing in the stack.
Owing to adopting technique scheme, a kind of polypropylene silencing drainage pipe of the present utility model is that mould production not only is convenient in the connection between stack and the gutter, and stable firm, good sealing effect with the beneficial effect of H type pipe fitting; H type pipe fitting is installed the effect convenient, that sealing effectiveness is good with having being connected of other outside tubing.
