Abstract
The utility model relates to a flow sensor, which belongs to a liquid flow sensor. The sensor 1 is fixedly connected to a positioning sleeve 3 which is fixedly connected with an overload protective sleeve 4; an outer sleeve 2 is connected with the overload protective sleeve 4 through threads; the overload protective sleeve 4 is fixedly connected with a fulcrum shaft 7; a flange disk 5 is connected with the overload protective sleeve 4 through threads. A corrugated diaphragm 6 is fixedly connected with the fulcrum shaft 7; a target rod 8 is connected with one end of the fulcrum shaft through threads; the overload protective sleeve bracket 9 is spliced with the flange disk 5. The utility model has the advantage of novel structure. Because a lever and a fulcrum are taken to transfer flow values, the sensor is stable and is not easy to generate exception when working; when a measured matter contains sundries, metering results are not influenced. Because of the structure, the working state is stable; the precision is enhanced; thus, the utility model can adapt occasions of high requirements.
Description
Technical field
The utility model belongs to a kind of liquid flow sensor.
Background technology
Resistance strain type sensor is used very wide in field of measuring techniques, owing to the pay attention to day by day to energy savings, so flow measurement technology is also very paid close attention to, so just impels their to obtain very fast the development.During present working sensor, owing to do not have overcurrent protection structure in the sensor, occur unusually easily, when containing foreign material in the measured matter, the result has considerable influence to metering, has influenced the raising of precision.
Summary of the invention
The utility model provides a kind of flow sensor, to solve present resistance strain type sensor job insecurity when measuring, the easy affected problem of precision.The technical scheme that the utility model is taked is: sensor 1 is fixedly connected in the locating sleeve 3; this locating sleeve 3 overlaps 4 with overload protection fixedlys connected; overcoat 2 is threaded with this overload protection cover 4; overload protection cover 4 is fixedlyed connected with fulcrum shaft 7; ring flange 5 is threaded with overload protection cover 4; convoluted diaphragm 6 is fixedlyed connected with fulcrum shaft 7, and target bar 8 is connected with the fulcrum shaft threaded one end, and overload protection dress support 9 is pegged graft with ring flange 5.Principle of work, when fluid flowed, the particle that flows impacted on the disc target, the stressed generation micro-displacement of target, this displacement passes on the sensitive element sensor 1 through fulcrum convoluted diaphragm 6 by target bar 8, and this displacement has reacted the size of flow.
Advantage of the present utility model is: novel structure, fluid flow function is acted on the crooked sensitive element through lever and fulcrum convoluted diaphragm in the power on the target, and strain on sensitive element again is converted to electric signal to power.Owing to adopt lever and fulcrum to transmit flow value, stable not being prone to unusually do not have influence to the metering result when containing foreign material in the measured matter when making working sensor.Because of its structure makes duty more stable, improved precision, it is adapted to require higher occasion, increase social benefit.
