Technical field

The present invention relates to liquidometer technical fields, and in particular to a kind of glass-tube liquid level meter with safeguard structure.

Background technique

The height of liquid medium is called liquid level in a reservoir, measures the instrument of liquid level liquidometer.Liquid level is calculated as material level gauge One kind of table.The type of liquidometer has tuning fork vibrating type, maglev type, pressure type, ultrasonic wave, sonar wave, magnetic turning plate, radar etc..

Current glass-tube liquid level meter structure does not protect structure, steam or gas to deposit glass tube end referring to Fig. 1 The phenomenon that long-time is worn, glass tube end is gradually thinned, when glass tube is thinned to its unbearable external pressure and inside When pressure, glass tube occurs to be crushed, and causes liquidometer to damage, it would be highly desirable to improve.

Summary of the invention

In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of designs reasonably to have protection knot The glass-tube liquid level meter of structure, increases safeguard structure, avoids steam or gas from directly directly contacting with glass tube end, prevents Steam or gas improve service life, practicability is stronger glass tube end wear.

In order to achieve the above objectives, present invention employs following technical proposals: it include gauge body, glass tube, pipe cap, Flange；The inside of gauge body is equipped with glass tube, and pipe cap is nested and fixed in the upper end of gauge body, and the upper end of glass tube is inserted It is located in the cavity of pipe cap；Flange is fixed on the side wall of pipe cap, and penetrates through and be arranged with pipe cap internal cavity；It also includes protection knot Structure；The protection structure is erected at the upper port of glass tube, and its lower port is plugged in the upper port of glass tube, glass Pipe, protection structure, pipe cap and the cavity of flange three penetrate through setting.

Further, the upper port of the gauge body is equipped with sealing ring, and the internal ring wall of sealing ring is set in glass On the upper end outer wall of glass pipe, the external annulus conflict of sealing ring is arranged on the inner wall of pipe cap.

Further, the cross section of the protection structure is " T " shape structure, and vertical end is plugged in the upper end of glass tube In mouthful, the periphery of horizontal ends is fixed on the inner wall of pipe cap.

Further, the upper end external annulus of the protection structure is an integral structure with pipe cap.

After adopting the above structure, the beneficial effects of the present invention are: the present invention provides a kind of glass with safeguard structure Pipe liquidometer, increases safeguard structure, and steam or gas is avoided directly directly to contact with glass tube end, prevents steam or gas Body improves service life glass tube end wear, and practicability is stronger.
