Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As depicted in figs. 1 and 2, a kind of magnetic double level gauge of heat insulation-type, including inner cylinder 1 are equipped with measurement in inner cylinder 1 and are situated between
Matter and magnetic float 2 are connected with vapour phase flange-interface 3 and liquid phase flange-interface 4 on 1 side wall of inner cylinder, are equipped with row in 1 bottom of inner cylinder
Dirty pipe 5, on sewage pipe 5 be equipped with blowdown valve 6, on the outside of inner cylinder 1 be equipped with shell 7, between inner cylinder 1 and shell 7 filled with every
Thermal medium 8 is equipped with the magnetic sheet 9 matched with magnetic float 2 on the outside of shell 7.
Preferably, vapour phase flange-interface 3 and liquid phase flange-interface 4 are set on the outer the same side of inner cylinder 1, and magnetic sheet 9 is set to inner cylinder 1
The other side.Such setting avoids magnetic sheet 9 and interferes with each other with vapour phase flange-interface 3, liquid phase flange-interface 4, influences to measure.
Preferably, the side wall of the shell 7 and 9 opposite side of magnetic sheet is skewed, and inner wall tilts upward extension.In reality
Border in use, insulation medium 8 between shell 7 and inner cylinder 1 can move down under the effect of gravity with using volume to reduce,
Such setting reduces insulation medium 8 with the distance moved down is used, and reduces the frequency of addition insulation medium 8.
Preferably, feed inlet 7.1 is offered on shell 7, is equipped on feed inlet 7.1 and is matched with feed inlet 7.1
