Abstract

The utility model relates to a magnetic reversing column type rotameter, which comprises a cylindrical shell [6], a magnetic float [5], an end cap [7], a fixing piece [3] and a fastening piece [4]. The magnetic float [5] can rise and fall with the variation of liquid flow in the cylindrical shell [6]. A display [1] is arranged in the vertical direction at the external side of the cylindrical shell [6]. A row of magnetic reversing columns [2] is longitudinally arranged in the display [1]. Different color coatings are arranged correspondingly to the magnetic pole N and the magnetic pole S. The utility model has the advantages that the observation is convenient, the structure is simple and the measured value is accurate.

Description

Magnetic turns over the post spinner-type flowmeter

Technical field

The utility model relates to a kind of flowmeter of measuring fluid, is that a kind of magnetic turns over the post spinner-type flowmeter specifically, and it mainly is to measure coloured or nontransparent transient liquid flows such as non-pulsation one-way fluid, especially latax, sewage, fruit juice.

Background technology

Traditional spinner-type flowmeter when measuring coloured or nontransparent liquid because cannot see or not see rotor residing position and influence the measurement of flow in fluid.Though a kind of magnet rotor flowmeter that fluctuates with the outer indicateing arm of magnet rotor attraction measurement tube can pass through the position of the position judgment rotor of indicateing arm, exist indicateing arm to be caused the inaccurate or inefficacy of measured value by problems such as unexpected viscous; Another kind of with a flat elongated unsteady indicateing arm measuring liquid level of plastic tube replacement that under the magnet rotor sucking action, can become bending generation folding line, but obviously have the coarse shortcoming of measured value.

Summary of the invention

The purpose of this invention is to provide that a kind of observation is convenient, simple in structure, measured value accurately magnetic turn over the post spinner-type flowmeter.It is to turn over post with magnetic to replace float indicateing arm or plastic tube, thereby the color of turning over post by magnetic is turned over the post flowmeter with the magnetic that the float lifting changes the measurement flow.

Magnetic provided by the invention turns over the post spinner-type flowmeter, comprise cylindrical shell, magnetic float, end cap, fixture and securing member, magnetic float can change and lifting with fluid flow in cylindrical shell, in the cylindrical shell outside display is arranged vertically, vertically have row's magnetic to turn over post in the display, corresponding its N, S magnetic pole have the coat of paint of different colours.

Described cylindrical shell is the little down big tapered tube of.

The cylindrical shell that fluid is flowed through is a little down big tapered tube, and rotor rises highly more, and the annulus area of rotor and tapered tube is big more, and then flow is big more.The post magnetic indication of turning over of flow develops according to law of buoyancy and magnetic couplings effect, when fluctuations in discharge, float in the cylindrical shell is lifting thereupon also, and the permanent-magnet steel in the float is delivered to on-the-spot display by magnetic coupling, drives red, turn over post in vain and overturn 180 °, when flow increases the liquid level rising, turn over the post adularescent and transfer redness to, when liquid level descends, turn over post and transfer white to by redness, the true altitude that the place, position, red white boundary of indicator reaches for the cylindrical shell inner fluid, thereby the indication and the measurement of realization flow.The utlity model has and observe convenient, simple in structure, measured value advantage accurately.

Description of drawings

Fig. 1 is a structural drawing of the present utility model.

Embodiment

With reference to Fig. 1, magnetic provided by the invention turns over the post spinner-type flowmeter, comprise cylindrical shell 6, magnetic float 5, end cap 7, fixture 3 and securing member 4, cylindrical shell 6 is the little down big tapered tube of, magnetic float 5 can change and lifting with fluid flow in cylindrical shell 6, it is characterized in that in cylindrical shell 6 outsides display 1 being arranged vertically, vertically have row's magnetic to turn over post 2 in the display 1, corresponding its N, S magnetic pole have the coat of paint of different colours.

When the cylindrical shell 6 that fluid is flowed through, along with the increase of flow, magnetic float 5 rises in cylindrical shell 6, when float 5 rises or descends with the variation of flow, magnetic turns over the red white two kinds of different colors of post conversion, reads the scale on position, place, position, red white boundary and the cylindrical shell 6, gets final product the flow of on-line measurement fluid.

Claims (2)

1, a kind of magnetic turns over the post spinner-type flowmeter, comprise cylindrical shell [6], magnetic float [5], end cap [7], fixture [3] and securing member [4], magnetic float [5] can change and lifting with fluid flow in cylindrical shell [6], it is characterized in that display [1] vertically being arranged in cylindrical shell [6] outside, vertically have row's magnetic to turn over post [2] in the display [1], corresponding its N, S magnetic pole have the coat of paint of different colours.

2, a kind of magnetic according to claim 1 turns over the post spinner-type flowmeter, it is characterized in that described cylindrical shell [6] is the little down big tapered tube of.
