Description
Technical field
The present invention relates to field of mechanical technique, and in particular to has arrived a kind of flange-type intelligent pressure transmitter.
Background technology
Intelligent pressure transmitter is combined the intelligent transmitter formed by sensor technology with microelectric technique, because it is in work(
Energy, precision, reliability, maintenance, more conventional analog transmitter improves a lot in configuration, has been widely used at this stage.Pick-up
The intelligence of device is mainly shown as the ability with self-monitoring, telecommunication, and because using micromechanics electronics processing technology, surpassing
Large-scale application-specific integrated circuit and surface mounting technique, and transmitter is made to have the high reliability, range ability wide and stablize
Temperature and pressure compensation performance.Existing energy pressure transmitter configurations design is unreasonable, and each modular construction connection of device is built on the sand, important
Pressure element isolation diaphragm poor corrosion resistance, isolation diaphragm outer diameter usually only 35mm or so, isolation diaphragm effective diameter is only
There are 25mm or so, the effective diameter of isolation diaphragm to have a great impact the performance of pressure transmitter, since isolation diaphragm is small, rigid
Degree is big, makes it possible to that pressure transmitter performance is unstable, and temperature drift is big during practice, and repair rate is high.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of flange-type intelligent pressures of structure design advantages of simple to become
Send device.
To solve the above-mentioned problems, the present invention provides a kind of flange-type intelligent pressure transmitters, including intelligent pressure to become
Send device ontology, flange base, isolation diaphragm, transition rings, sealing stake and fixing bolt；The intelligent pressure transmitter ontology is divided into
There are fixing bolt, fixing bolt to have flange base, the pressure transmitter ontology passes through fixing bolt and flange base phase

As a further improvement on the present invention, the outer diameter of the isolation diaphragm is 66mm, and the effective diameter of isolation diaphragm is
60mm。
Using the above structure, advantage is：Structure of the invention designs advantages of simple, and the outer diameter of isolation diaphragm is
The effective diameter of 66mm, isolation diaphragm are 60mm, and isolation diaphragm outer diameter increases to 66mm by original 35mm, isolation diaphragm
Effective diameter increases to 60mm by original 25mm, and the increase of the effective diameter of diaphragm has so that the performance of product is substantially improved
Effect solves existing isolation diaphragm since isolation diaphragm is small, rigidity is big, and pressure inverting is made it possible to during practice
Device performance is unstable, and temperature drift is big, the high problem of repair rate, and the transition rings pour into a mould the knot that is integrally formed by polytetrafluoroethylene (PTFE)
Structure, polytetrafluoroethylene (PTFE) corrosion resistance is splendid, and the isolation diaphragm is set in transition rings, can be effectively protected isolation diaphragm, have
Effect solves the problems, such as existing isolation diaphragm poor corrosion resistance.The flange base is connected with transition rings by argon arc soldering
It connects；Transition rings bottom end is connected with sealing stake by argon arc soldering, and the sealing stake is connected with isolation diaphragm by argon arc soldering
It connects, flange base, transition rings, isolation diaphragm, sealing stake are integral using argon arc welding welding after compressing, and effective solution is existing
Each modular construction of energy pressure transmitter connect unsteady problem.
