Abstract
The utility model relates to a flowrate metering device, more particularly relates to an integrated elbow flowmeter that organically combines discrete devices such as a differential pressure transmitter, a three section valve module and an elbow sensor. The differential pressure transmitter of an inter embed secondary display instrument is fixed right above the elbow sensor by a bracket, the three section valve module that is butted with a positive and a negative pressure signal input ports of the differential pressure transmitter is positioned below the differential pressure transmitter by the bracket and two connecting pipelines, the lower ends of the two connecting pipelines are respectively fixedly connected with positive and negative sampling pressure bodies at the two sides of the differential pressure transmitter. The integrated elbow flowmeter has the advantages of novel structure, easy installation, high measuring accuracy, small volume, low cost, wide adaptation range (can be applied for a 90-degree L-shaped elbow sensor, a straight pipe and an S-shaped elbow sensor) and strong practicability, etc.
Description
Technical field:
The utility model relates to flow measurement device, particularly a kind of integrated elbowmeter that separation devices such as differential pressure transmitter, three valve modules, Bending Tube Sensor are organically combined.
Background technology:
Elbowmeter is widely used in liquid medium, the gas medium in the production process of metallurgy, chemical industry, heating power, electric power, the measurement of steam medium flow, present existing elbowmeter all is to be assembled in test site by divergence type devices such as Bending Tube Sensor, secondary indicator gauge, transmitter, three valve modules, and incorporate winding pipe flow rate metering device is not arranged as yet.Because of each discrete device is produced by different specialized factories respectively, when therefore above-mentioned device is assembled, often, make between the device not match because of Product Renewal, installation dimension change, bring very burden to Installation and Debugging; Because software engineering does not catch up with the needs of production, select shortcomings such as the above-mentioned device architecture that advances is backward, volume is heavy, precision is not high, usable range is narrow, function is few, the life-span is short sometimes, so that influence accuracy of measurement system and stability again.
Summary of the invention:
Goal of the invention of the present utility model is intended to improve the weak point in the above-mentioned background technology, and provide that a kind of structure advanced person, volume are little, in light weight, long service life, easy for installation, good stability, integrated elbowmeter that measuring accuracy is high.
Realize that foregoing invention purpose technical scheme is: this integrated elbowmeter comprises devices such as differential pressure transmitter, three valve modules, Bending Tube Sensor, connecting pipe, the differential pressure transmitter of embedded secondary Displaying Meter by support be fixed on Bending Tube Sensor directly over, three valve modules that dock with differential pressure transmitter positive and negative pressure signal input are installed in the below of differential pressure transmitter by this support and two connecting lines, and the lower end of two connecting lines is fixedly connected with the positive and negative pressure body of Bending Tube Sensor both sides respectively.The positive and negative pressure of taking out from Bending Tube Sensor both sides pressure body by two connecting lines is sent into the differential pressure transmitter of embedded secondary Displaying Meter through three valve modules, and its differential pressure can directly demonstrate rate-of flow after converting simulating signal to.
The integrated elbowmeter of implementing according to this technical scheme, compare with background technology have novel structure, easy for installation, measuring accuracy is high, volume is little, cost is low, wide accommodation (can be used on 90 degree L type Bending Tube Sensors, the straight tube on the S type Bending Tube Sensor), advantage such as practical.
