Abstract
A high precision balanced type steam flowmeter capable of temperature and pressure automatic compensation comprises a cylindrical casing and a float, wherein the inner wall of the casing is in shape of an inverted truncated cone, and the float vertically moving along with flow rate is disposed in the casing. The high precision balanced type steam flowmeter is characterized in that a magnetic component is disposed on the float, a magnetic induction component capable of receiving magnetic signals transmitted by the magnetic component on the float is fixedly disposed on the outer side of the casing, and a temperature sensor is further fixed to the outer side of the casing. The high precision balanced type steam flowmeter utilizes the magnetic induction component to transmit the displacement signal of the float to a secondary meter for further processing, and then combining with the temperature sensor, the steam flow can be measured. Therefore, the high precision balanced type steam flowmeter can be free of pipelines made of transparent materials, thereby having low temperature and pressure limitation. The high precision balanced type steam flowmeter overcomes the shortage that the continuously moving float causes inconveniences to visual reading. The high precision balanced type steam flowmeter is adaptable to automation occasions.
Description
[technical field]
The utility model relates to a kind of metering steam flow instrument, particularly a kind of high precision balanced type steam-flow meter with the automatic compensation of temperature, pressure.
[background technology]
The roughly porose board-like flowmeter of instrument, pibtot's tub formula flowmeter, turbine meter, eddy currents flowmeter and the float type flow meter etc. of metering steam flow in the prior art.These flowmeters in use all respectively have its characteristics and deficiency.Orifice-plate flowmeter is simply solid, and precision is higher, and cost is also relatively low, but its shortcoming is: range ratio is restricted, and orifice plate distortion or wearing and tearing cause that blocking pipe or metering influence precision, and installation length is subjected to certain limitation; Pibtot's tub formula flowmeter convection cell resistance is little, low price and simple, and applicable different bore, but its shortcoming is: range ratio is low, and the hole of bottom was easily stopped up when steam moisture was big; The range ratio height of turbine meter, precision is also better, relative cost is lower, but can cause the deviation of measuring during pressure surge, as flow fluctuation, also can be owing to the sluggish error in dipping that causes, the fragile precision that influences of impeller, cross when flow and can cause continuous data to lose when low, viscosity also can influence precision simultaneously, also can damage impeller when meeting with impurity; Eddy currents flowmeter has good range ratio, movement-less part, choked flow is also low, but when flow velocity was low, metering reading was on the low side even be zero, also can cause some problems to produce during big flow, the vibration of itself also can cause error, have relatively high expectations installing, otherwise can cause error, the upstream needs very long straight length in addition.Float type flow meter is because linear output, the range ratio height, simply solid, advantages such as step-down is less and constant substantially are widely used in various operating mode occasions, receive praises from customers, but its transparent pipeline is limited by temperature and pressure, reading is usually by range estimation, and float is moving always, so many inconvenience is also arranged when using.
[summary of the invention]
Technical problem to be solved in the utility model is to overcome existing defective in the above-mentioned prior art, and a kind of high precision balanced type steam-flow meter with the automatic compensation of temperature, pressure is provided.
The utility model has adopted following technical proposal to solve its technical matters: a kind of high precision balanced type steam-flow meter with the automatic compensation of temperature, pressure, comprise cylindrical housings, this inner walls is round table-like, in the housing that one float that moves up and down with the flow size is provided with, it is characterized in that: be equipped with magnetic element on this float, the outer survey of housing is fixedly equipped with the magnetic induction part that can accept the magnetic signal that magnetic element provides on the float, and the outer survey of housing also is fixedly equipped with temperature sensor.
The utility model utilizes magnetic induction part, the displacement signal of float is passed supply with secondary instrument and further handle, and just can realize measurement to steam mass flow in conjunction with temperature sensor again.Therefore the utility model can not adopt the pipeline of transparent material, and it is subjected to the temperature and pressure restriction less.Solved float and moved always, the defective of inconvenience has been arranged by the range estimation reading.Be adapted at the utilization of robotization occasion.
[description of drawings]
Accompanying drawing is the utility model structural representation.
Each sequence number is expressed as respectively among the figure:
1-flange disc, 2-bolt and nut, 3-housing
4-inner walls, 5-float, 6-magnetic element
7-magnetic induction part housing, 8-magnetic induction part, 9-temperature sensor
[embodiment]
The utility model will be further described below in conjunction with embodiment and accompanying drawing.
With reference to accompanying drawing, the utility model comprises the cylindrical housings 3 of the non-magnetic conductive material of a stainless steel, this inner walls 4 is round table-like, in the housing 3 that one float 5 that moves up and down with the flow size is provided with, on this float 5, be equipped with magnetic element 6, the outer survey of housing 3 is fixedly equipped with the magnetic induction part 8 that can accept the magnetic signal that magnetic element 6 provides on the float 5, and housing 3 outer surveys also are fixedly equipped with temperature sensor 9, and this temperature sensor 9 can adopt thermistor.
The present embodiment middle shell 3 outer magnetic induction parts 8 that are fixedly equipped with of surveying are the compact arranged tongue tube of a row.During the utility model work, steam is advanced along a direction among the figure, and directly act on float 5, make float 5 to top offset, inner walls 4 increases gradually with the gap of float 5 peripheries, when steam just in time equaled float 5 and is being measured quality in the steam to the acting force of float 5, the float 5 stressed equilibrium states that are in rested on a corresponding height.At this moment, 8 effects of magnetic element on the float 5 and housing 3 are outer surveys corresponding magnetic induction part 8---tongue tubes, and the corresponding electric signal that reed pipe is produced passes and supplies with secondary instrument and further handle.The signal that provides in conjunction with temperature sensor 9 makes secondary instrument realize automatic compensation function to temperature or pressure when further handling, thereby has realized steam mass flow is carried out high-precision metering again.
