Utility model content
The purpose of this utility model provides a kind of simple in structure in order to solve above-mentioned deficiency exactly, under low temperature environment without external heating, the antifreeze magnetic float liquidlevel meter that some liquid medium can not exert an influence yet under hot environment.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
Antifreeze magnetic float liquidlevel meter, it includes main pipe, magnetic ball float, ring flange and blowoff valve, described magnetic ball float is positioned at main pipe, the wall shell of described main pipe consists of inside and outside double wall housing, between this inside and outside double wall housing, form airtight chamber, on described main pipe, offer vapour phase connecting hole and liquid phase connecting hole, this vapour phase connecting hole and liquid phase connecting hole are connected the inside of main pipe with outside, on described main pipe, be also provided with and take out negative tube, this is taken out negative tube and is connected with airtight chamber, described airtight chamber by around sidewall chamber and coupled logical bottom chamber form, described ring flange is the top that shutoff shape is arranged on main pipe, described liquid phase connecting hole is connected with the inner bottom part of main pipe.
The height of described bottom chamber is 2-5 times of sidewall chamber width.
The described negative tube of taking out is connected with bottom chamber.
The described negative tube of taking out is also equipped with protective cover outward.
The ring flange at described main pipe top is by lower fixed flange and upper mounting flange is fixed with each other forms, on this lower fixed flange and upper mounting flange, offer respectively corresponding through hole, the through hole of mounting flange is revolved and is equipped with screw plug on described.
The ring flange at described main pipe top is by lower fixed flange and upper mounting flange is fixed with each other forms, on this lower fixed flange and upper mounting flange, offer respectively corresponding through hole, the through hole of mounting flange is provided with atmospheric valve on described.
More than magnetic ball float in described main pipe is positioned at the hole central axis of liquid phase connecting hole.
The down blow mouth of described blowoff valve is external thread shape.
The ring flange at described main pipe top is by lower fixed flange and upper mounting flange is fixed with each other forms, and on this lower fixed flange, offers through hole, and the diameter of this through hole is greater than the maximum gauge of magnetic ball float.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: simple in structure, result of use is good, by airtight chamber by around sidewall chamber and coupled logical bottom chamber form, make sidewall and the bottom of main pipe all obtain isolated protection effectively, the bottom that has effectively guaranteed main pipe can not produce solidification phenomenon yet, simultaneously, liquid phase connecting hole is connected with the inner bottom part of main pipe, make the liquid of main pipe inner bottom part often in flow state, again effectively avoided main pipe inner bottom part to occur solidification phenomenon; Increase the space of bottom chamber and take out negative tube and be connected with bottom chamber, be conducive on the one hand to completely cut off well the temperature bottom main pipe, be also conducive on the other hand the needs that whole airtight chamber vacuumizes.
