Abstract
The utility model relates to a magnetic reversing column liquid level gauge, which mainly comprises a floater and a magnetic turning board, wherein, the floater is arranged at the lower end of a stainless steel tube with an inner lining made of polytetrafluoroethylene; the magnetic turning board is distributed outside the stainless steel tube along the pipe diameter; openings are formed close to the two ends of the stainless steel tube and connected with flanges; the inner part of the stainless steel tube is integrally lined with the inner lining made of polytetrafluoroethylene; in addition, the inner lining made of polytetrafluoroethylene extends outwards from the openings formed on the stainless steel tube along the orifices, then turns over at flange mouths, and is jointed with the outer sides of the flange mouths. The magnetic reversing column liquid level gauge adopts the integral inner lining made of polytetrafluoroethylene, reduces flanged connection, and reduces the potential hazard to operation safety caused by leakage points; the magnetic turning board can be arranged in the position that the flanges are placed, so that a measuring dead area can be avoided, and the actual height of a liquid level can be reflected accurately; and significantly, the magnetic reversing column liquid level gauge reduces material, and lowers the cost.
Description
Technical field
The utility model relates to a kind of liquid level gauge, especially a kind of magnetic turning column liquid level meter of integral lining teflon.
Background technology
Magnetic turning column liquid level meter is also referred to as magnetic turnover panel liquid level gauge, and its structure is mainly produced based on buoyancy and magnetic force principle design.The position of float (abbreviation magnetic float) in measured medium that has magnet influenced by buoyancy.The magnetostatic couple of force cooperation that the variation of liquid level causes variation, magnetic float and the magnetic of magnetic float position to turn over post (also becoming the magnetic turnover panel) flips an angle (magnetic turns over the different color of post surface applied) with causing magnetic to turn over post, and then the situation of the interior liquid level of reflection container.
The lining teflon magnetic turning column liquid level meter is compared magnetic turnover panel liquid level gauge, what be mainly reflected in 304 housings the inside contacting with fluid medium is the teflon teflon, be commonly called as " plastics king ", it is the polymkeric substance that is polymerized by tetrafluoroethylene monomer, be the transparent or opaque wax of a kind of PE of being similar to, its density is 2.2g/cm
3Water-intake rate is less than 0.01%, and its chemical constitution is similar to PE, and just the whole hydrogen atoms at teflon all can be replaced by fluorine atom.Because C-F key bond energy height, stable performance, Gu and its chemical resistance is splendid, can bear to fluoridize medium and be higher than the NaOH of 300 degree except the alkaline metal of fusion to have the effect of strong acid (comprising five water) and strong oxidizer reductive agent and various organic solvents.But the technology of inner liner polytetrafluoroethylene is quite complicated, and whole liquid level gauge carries out lining, almost can not realize.So the market appearance is a kind of liquid level gauge is divided into three sections, does the threeway of 2 lining fluorine and be added with a straight tube again, flange is formed by connecting.Several drawbacks are so just arranged: 1, all the flange connection, must increase the leak point, bring hidden danger to handling safety.2, the place of flange is arranged, can not put the magnetic turnover panel and must form and measure the blind area.Make troubles for actual operation, can not accurately reflect actual liquid level.3, it has increased material, has just increased cost.
The utility model content
Main task of the present utility model is to provide a kind of inner liner polytetrafluoroethylene magnetic turning column liquid level meter, and this liquid level gauge liner is whole polytetrafluoroethyllining lining, does not limit the setting of magnetic turnover panel in any zone, forms the characteristics of measuring non-blind area.
In order to solve above technical matters, a kind of magnetic turning column liquid level meter of the present utility model is mainly in the stainless-steel tube lower end of inner liner polytetrafluoroethylene and establishes float, and the outside constitutes along caliber distribution magnetic turnover panel; Described stainless-steel tube is located perforate respectively near two ends, and is connected with flange; Its innovative point is: described polytetrafluoroethyllining lining is whole to be served as a contrast in stainless-steel tube, and stretches out along the aperture and applying outside flange port place flange and flange port at the stainless-steel tube tapping.
Advantage of the present utility model is: the utility model adopts this integral lining tetrafluoroethene, has reduced the flange connection, reduces the leak point, brings hidden danger to handling safety; And, can put the magnetic turnover panel and do not had the measurement blind area in the place that flange is arranged.Bring convenience for actual operation, accurately reflected actual liquid level; Importantly it has reduced material, reduces cost.
Description of drawings
Fig. 1 is the structural representation of inner liner polytetrafluoroethylene liquid level gauge of the present utility model;
Fig. 2 is the structural representation that inner liner polytetrafluoroethylene liquid level tube of the present utility model is connected with flange.
Embodiment
As shown in Figure 1, 2, described inner liner polytetrafluoroethylene magnetic turnover panel liquid level gauge is made of magnetic turnover panel 1, liquid level gauge pipe 2, float 3, flange 4 and flange 8.
Above-mentioned magnetic turnover panel equidistantly distributes on the tube wall of liquid level gauge pipe 2, liquid level gauge pipe 2 inner liner polytetrafluoroethylene liners 5, and its two ends are connected with flange 4 respectively; And on the side of liquid level gauge pipe 2, have hole 6,7 near two-port, also respectively connect a flange 8 that has hole 9 and 10 at tapping, then, at the be tightly connected steel pipe 11 of lining teflon liner of the tapping of two end flanges 8, and connect lap joint flange 12 at the end of steel pipe 11, connect joint flange 13 in lap joint flange 12 outsides.Innovative point of the present utility model just is: the polytetrafluoroethyllining lining 5 in the polytetrafluoroethyllining lining at flange 8 places and the liquid level tube 2 is for one, global formation.
