Municipal drainage pipeline flowmeter installation auxiliary equipment

Abstract

The invention relates to the technical field of flow meters, and discloses municipal drainage pipeline flow meter installation auxiliary equipment which comprises a frame, connecting pipes are fixedly installed at the left end and the right end of the frame correspondingly, fixing plates are fixedly installed in the connecting pipes, and flow guide grooves are formed in the end faces, away from the frame, of the fixing plates. Moving grooves are formed in the upper end and the lower end of the flow guide groove correspondingly, and connecting rods are movably installed in the moving grooves. According to the municipal drainage pipeline flowmeter installation auxiliary equipment, water enters a connecting pipe, liquid enters a flow guide groove in the connecting pipe, due to the design of a groove, the groove can move rightwards by a certain distance under the potential energy effect of the water, and at the moment, the connecting rods move on the moving grooves in cooperation with the effect of the moving grooves; the connecting rods drive the ejector rods to move upwards in the connecting pipe, extrusion force is applied to the rubber pad on the outer wall of the connecting pipe, at the moment, contact force between the rubber pad and the to-be-detected pipeline becomes larger, and therefore the sealing effect is better.

Description

technical field [0001] The invention relates to the technical field of flowmeters, in particular to an auxiliary device for installing flowmeters in municipal drainage pipes. Background technique [0002] A flowmeter refers to the overall instrument of the measured flow at a selected time interval. Simply put, it is an instrument used to measure the fluid flow in a pipeline or an open channel. Flowmeters can be divided into differential pressure flowmeters, rotameters, Throttle flowmeters, etc., can be classified according to the mechanism: liquid flowmeters and gas flowmeters. [0003] In the process of using the flowmeter, the flowmeter needs to be installed in the pipeline to be tested, and the flow can be measured after the liquid flows through the flowmeter. It leads to rusting of its internal structure and is prone to failure. Long-term liquid corrosion will cause the flowmeter to be fixed weakly and cause liquid leakage. [0004] In view of the above-mentioned probl...
