Abstract
A glass rotameter comprises a conical glass tube with the big end up, a floater capable of moving up and down is arranged in the conical glass tube, an air inlet is arranged below the conical glass tube, an adjusting valve is mounted on a passage of the air inlet, an air outlet is arranged above the conical glass tube, and a spring is mounted on the upper portion inside the conical glass tube. The glass rotameter has the advantages of simple structure and convenience in use, and the floater can be prevented from being collided with the top or can be kept from getting close to the air outlet to be absorbed by an air flow due to an overlarge impacting air flow so as to cause air outlet blockage.
Description
Technical field
The utility model relates to a kind of apparatus for metering fluids, is mainly a kind of glass rotameter.
Background technology
The glass rotameter pressure loss is little and constant, measurement range is wider, reliable operation and scale linearity, easy maintenance, less demanding to flow development length before and after instrument, be a kind of simple, convenient reading, purposes instantaneous delivery measurement instrument very widely of using.Be mainly used in, in each departments such as chemical industry, oil, light industry, medicine, chemical fertilizer, chemical fibre, industrial sintering furnace stove, food, dyestuff, environmental protection and scientific research, being used for measuring the flow of single-phase non-pulsating fluid (liquid or gas).
The main measuring sensor of present glass rotameter is a vertically arranged lower little large tapered glass tube and at interior float moving up and down.When fluid is during from bottom to top through tapered glass tube, between float is upper and lower, produce pressure reduction, float rises under this differential pressure effect.In the time that the suffered buoyancy of power, the float of this rising and viscosity lift equate with the gravity of float, float is in equilibrium position.Therefore, the fluid flow of the flowmeter of flowing through and float lifting height, and between the actual internal area of flowmeter, exist certain proportionate relationship, the position height of float can be used as flow and measures.
Such utilization is in the time of the by-pass valve control of manually outwarding winding, and due to slowly stable increase of air-flow, glass rotameter does not have problems in using, if but gas circuit is during by solenoid control, because gas circuit is unexpected unlatching, the fluid flow entering increases suddenly, float is because the impulse force that is subject to fluid rises, in the time that impulse force is larger, float and top are clashed into, may cause top to be damaged or float is stuck in glass tube top, in the time that float is stuck in glass tube top, the residing position of flowmeter float is not the power that fluid rises, when the buoyancy that float is suffered and viscosity lift equate with the gravity of float float in position, if the position height of float is now measured as flow, can cause misleading to analysis and the result of producing or test.Particularly adopt supervisor to control total flow, the words of the mode then being entered respectively by multiple glass rotameter branch, may occur that partial discharge meter is greater than setting value because being stuck in top flow, and other not jammed flowmeter flows are lower than the phenomenon of setting value, affect the consistance of production or experimental result.
Summary of the invention
The purpose of this utility model is to provide a kind of glass rotameter, can prevent that float and top from clashing into, to make up the deficiencies in the prior art.
The purpose of this utility model is achieved in that a kind of glass rotameter, comprise lower little large tapered glass tube, in tapered glass tube, there is float moving up and down, there is air intake opening tapered glass tube below, variable valve is installed on air intake passage, there is gas outlet tapered glass tube top, in tapered glass tube inner and upper, spring is installed.
By implementing the utility model, can prevent that float and top from clashing into, or cross the too close gas outlet of ambassador's float and adsorbed by air-flow due to impact air-flow, cause gas outlet obstruction; The utility model is simple in structure, easy to use.
The utility model is described further by embodiment below in conjunction with accompanying drawing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1 is air intake opening, the 2nd, and variable valve, the 3rd, float, the 4th, tapered glass tube, the 5th, spring, the 6th, gas outlet.
Embodiment
Embodiment 1
A kind of glass rotameter, comprise lower little large tapered glass tube 4, in tapered glass tube 4, there is float 3 moving up and down, there is air intake opening 1 tapered glass tube 4 belows, on air intake opening 1 passage, variable valve 2 is installed, there is gas outlet 6 tapered glass tube 4 tops, in tapered glass tube 4 inner and upper, spring 5 are installed.
When use, glass rotameter is installed in the gas circuit of controlled by solenoid valve, variable valve 2 is adjusted to appropriate opening degree, in the time that solenoid valve is opened, air-flow enters tapered glass tube 4 from air intake opening 1 through variable valve 2, promote to move on float 3, because tapered glass tube 4 is lower little upper macrostructure, the degree of moving on float 3 is larger, flow through the more slow of float 3 peripheries, the thrust that float 3 is subject to is less, and final float 3 can be stabilized to tapered glass tube 4 certain altitudes, can read by the height of float 3 flow of air-flow; In the time that solenoid valve is opened suddenly, have impact air-flow and enter tapered glass tube 4, float 3 has a spring process, when float 3 snaps into tapered glass tube 4 tops, can be subject to buffering and the bounce-back of spring 5, prevent that float 3 from breaking or stopping up gas outlet 6 at tapered glass tube 4 tops.
