Split, influence the safety in utilization of metal expander, and the walled metallic structure of metal expander has Korrosionsmedium in conveying
When it is easily damaged, can further reduce metal expander service life, increase potential safety hazard.
Utility model content
The utility model provides a kind of explosion-proof metal expander, easy because of pressure at least to solve expander in the prior art
It is excessive to cause the problem of expander ruptures.
The utility model provides a kind of explosion-proof metal expander, including flange, bellows, guide shell, blast ring and otic placode；
The guide shell is enclosed in bellows, is connected with flange, and the guide shell includes left guide shell, right guide shell, the left water conservancy diversion
Cylinder right-hand member and right guide shell left end concentric gap fit inside metal expander, the left guide shell right-hand member are left with right guide shell
There is gap in the fit position at end；The blast ring is connected with bellows, and the blast ring is provided with pressure sensitive sensor, pressure
Power display and relief valve；The otic placode includes left otic placode and auris dextra plate, and the left otic placode is used for the connection of bellows and flange,
The auris dextra plate is used for the connection of flange and blast ring.
Further, the bellows is made up of three-decker, and scale resin corrosion-inhibiting coating, first are followed successively by from inside to outside
Metal level, second metal layer, the first metal layer use non-corrosive metal (NCM) material.
Further, the scale resin corrosion-inhibiting coating is organosilicon flake anticorrosive paint layer.
Further, the first metal layer is ferritic stainless steel.
Further, the second metal layer is 316L stainless steel layers.
The utility model compared with prior art, by installing blast ring on metal expander, using on blast ring
Pressure sensitive sensor is monitored in real time to pressure medium, and shows pressure value by pressure display unit, is available for staff
Medium conveying environment in metal expander is monitored in real time, can be by opening letting out on blast ring when pressure value is too high
Pressure valve carrys out pressure medium in dissolution medium, reduction metal expander, it is ensured that using for metal expander is safe, prevents expansion of metal
Device is because internal pressure is excessive and produces explosion.
Brief description of the drawings
Fig. 1 is the utility model embodiment schematic diagram；
Fig. 2 is the utility model embodiment close-up schematic view.
Embodiment
In order that those skilled in the art more fully understand the utility model scheme, it is real below in conjunction with the utility model
The accompanying drawing in example is applied, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only the embodiment of the utility model part, rather than whole embodiments.Based on the reality in the utility model

When the scope for belonging to the utility model protection.
It should be noted that term " first " in specification and claims of the present utility model and above-mentioned accompanying drawing,
" second " etc. is for distinguishing similar object, without for describing specific order or precedence.
A kind of explosion-proof metal expander is provided according to the utility model embodiment, as depicted in figs. 1 and 2, including flange
1st, bellows 3, guide shell, blast ring 6 and otic placode；The guide shell is enclosed in bellows 3, is connected with flange 1, the guide shell
Including left guide shell 4, right guide shell 5, the left right-hand member of guide shell 4 and the right left end of guide shell 5 are coaxial inside metal expander
There is gap in gap fit, the fit position of the left right-hand member of guide shell 4 and the right left end of guide shell 5；The blast ring 6 and ripple
Pipe 3 is connected, and the blast ring 6 is provided with pressure sensitive sensor 62, pressure display unit 61 and relief valve 63；The otic placode bag
Left otic placode 2 and auris dextra plate 7 are included, the left otic placode 2 is used for the connection of bellows 3 and flange 1, and the auris dextra plate 7 is used for flange 1
With the connection of blast ring 6.
Wherein, there is gap in the fit position of the left right-hand member of guide shell 4 and the right left end of guide shell 5, and medium is full of by space
Space between bellows 3 and guide shell, pressure sensitive sensor 62 determines guide shell by monitoring the pressure of medium herein
Interior pressure medium.
The utility model embodiment utilizes the pressure sensitive on blast ring 6 by installing blast ring 6 on metal expander
