Abstract
The utility model discloses a fixed pressure difference type flowmeter which comprises a circulating pipeline, flanges arranged on the two ends of the circulating pipeline, and a dial gauge arranged on the circulating pipeline, and a hollow plate arranged in the inner cavity of the circulating pipeline. The dial gauge comprises a gauge casing, a panel, a cursor, a balance spring connected with the cursor, a big gear and a small gear joggled at the middle part of the panel, and a corrugated tube eccentrically fixed and connected with the big gear, and one end of the corrugated tube is arranged on the circulating pipeline. The utility model has the advantages that the operation is simple, the reading is accurate, and the price is low.
Description
Affiliated technical field
The utility model relates to a kind of constant differential pressure flowmeter, belongs to the field of measuring technique of fluid.
Background technology
Present glass rotameter is the PC series (four column types) of USSR (Union of Soviet Socialist Republics), and weak point is that specification is out of proportion, does not have protective equipment; China's LZB series flowmeter structure is that liquid passes through glass tube, and inflow point is provided with float, and scale is arranged on the float, and liquid is during by import, and the scale measurement flow by float points to exists accuracy poor, and the high deficiency of price.
Summary of the invention
The purpose of this utility model provides a kind of easy to operate, cheap, accurate constant differential pressure flowmeter of reading.
The purpose of this utility model is achieved in that it comprises the flange at circulation pipeline, circulation pipeline two ends and is located at indicating gauge on the circulation pipeline, circulation pipeline inner chamber is fitted with hollow plate, the large and small gear of the hairspring that indicating gauge is connected by watchcase, panel, pointer and pointer, the engagement of panel middle part reaches with the eccentric affixed corrugated tube of gear wheel to be formed, and an end opening of corrugated tube is in the circulation pipeline.
Corrugated tube and gear wheel are by screw retention.
The obtained technical progress of the utility model is: the form that the utility model adopts the circulation pipeline to establish indicating gauge, fluid reacts to behind the corrugated tube by the hollow plate of circulation pipeline inner chamber, displacement by corrugated tube changes, drive gear wheel together with the pinion rotation that is engaged with, pass to pointer by the hairspring on the pinion wheel again, can on panel, flow reading be indicated more accurately.
