Material outlet and sewage draining exit, the position between the rear end of described fluorine plastic tube and middle-end is provided with second material import and evacuation port,
The rear and front end portion of the described fluorine plastic tube the same black box of attachment structure respectively, this black box includes: the end with housing
The lower flange that portion connects, described housing locks described fluorine plastic tube by lower flange, and the end loops of described fluorine plastic tube are around setting
There is end plate, the lower end of described end plate is provided with the housing seal flange with lower flange locking, and the port of described fluorine plastic tube is passed through
The gland being provided with and o type circle form first material import or first material outlet, and described gland wraps up the end of end plate, described
It is provided with gap, the end of described gland is provided with interface, gland located at front end forms the between gland and housing seal flange
One material inlet and the gland located at rear end form first material outlet.
Further, described gap for 10-12mm.
Further, the junction in described lower flange and housing is provided with the first rubber blanket.
Further, it is provided with the second rubber blanket between described housing seal flange and the junction of lower flange.
The beneficial effects of the utility model are: the utility model is adopted and is provided with double sealing structure: the first sealing structure is:
Gland, ptfe sealing ring and end plate are locked by bolt, realize sealing tube side；Second seal structure is: end plate plate, housing seal method
Orchid, rubber blanket, back-up ring and lower flange are locked by bolt, realize sealing shell side；Can be to greatest extent by two layers of sealing structure
Realize the tightness of heat exchanger.Stay between this outer press cover and housing seal flange 10-12 about space, expose end plate, if
Ptfe sealing ring lost efficacy, and tube side material spills and can flow on end plate, facilitates patrol officer to observe；Equally, if the first silica gel
Circle lost efficacy, and shell material spills and can flow on end plate, housing seal flange and lower flange, facilitates patrol officer to observe.So,
Can prevent because seal failure leads to leak in time and abnormal material occurs.
Brief description
Fig. 1 is a kind of structural representation of fluorine plastic tube shell heat exchanger.
