It is soft not enough although corrugated expansion joint can not be limited by angle and direction and arbitrarily bent, because It is made of metal after all, so in some extent, or it is soft like that without normal direction rubber hose, in addition can not be compatible all of Gas port, that is to say, that the combustion gas interface having can not use corrugated stainless steel tubing, this use for just giving people above brings Limitation.
Utility model content
The purpose of this utility model is to provide a kind of corrugated expansion joint, to solve to propose ripple in above-mentioned background technology It is soft not enough although pipe compensator can not be limited by angle and direction and arbitrarily bent, because being after all metal system Into, it is so in some extent or soft like that without normal direction rubber hose, in addition can not compatible all of gas port, also It is that the combustion gas interface said can not use corrugated stainless steel tubing, the use that this just gives people above brings asking for limitation Topic.
To achieve the above object, the utility model provides a kind of following corrugated expansion joint of technical scheme, including work connects Pipe, bellows, first flange, pull bar, nut, pad, second flange, bearing pin, riser, Circular Plate, the first otic placode, the second ear Plate, guide shell, thermal insulation layer, hickey, through hole, extension tube attached and metal connecting hose, the right-hand member of the work adapter are connected with ripple Line pipe, and its left end is connected with first flange, and pull bar is mounted with the first flange, and the first ear is provided between the pull bar Plate and the second otic placode, and it is provided with nut and pad between the first otic placode, the second otic placode, the rear end of the bellows is set The right-hand member for having bearing pin, the bearing pin is mounted with riser, and the rear end of second otic placode is provided with second flange, the work adapter Inwall guide shell is installed, thermal insulation layer is provided with the inside of the guide shell, be provided with the outer surface of the first flange Hickey, and its upper end is movably installed with extension tube attached, the surrounding of the hickey is mounted with through hole, the first flange and The front end of second flange is connected with metal connecting hose.
Preferably, Circular Plate is installed on the outer surface of the work adapter.
Preferably, the material of the bellows is aluminium.
Preferably, stuffed heat insulated filler in the chamber of the thermal insulation layer.
Preferably, the extension tube attached and metal connecting hose are detachable connecting device.
Compared with prior art, the beneficial effects of the utility model are:The corrugated expansion joint uses metal connecting hose, tool There is excellent flexibility, corrosion resistance, heat-resisting quantity can be attached in pipeline to any direction, to temperature-compensating and absorption Vibration, reduction noise, change medium conveying direction, improve its service life;The material of bellows is aluminium, because aluminium belongs to soft gold Category, intensity less, there is good ductility;Increase extension tube attached, extension tube attached can be connected on metal connecting hose, according to actual need The joint dimension size to be connected, connects various sizes of extension tube attached, makes its compatibility stronger.
