Technical field
The present invention relates to flowmeter, be specifically related to the anti-blocking flowmeter of a kind of high precision.
Background technology
Due to the reinforcement of environmental protection dynamics and to the requirement of commercial production energy-saving consumption-reducing, industrial processes are more and more required to accurate control, so require new measuring-control system to carry out effective observing and controlling to industrial link.We also do not have professional measurement instrument for the measurement of dirty gas in the commercial production link now, all to adopt conventional TT&C system, what have does not just have a clogging-preventing measures at all, passing through of having installed purging system additional and is applied to this systematic survey, often causes effectively continuous coverage of measuring system, or purges unreasonable, dirty stifled serious, measuring accuracy is poor, can not effectively participate in industrial automation system and control, and maintenance cost is high.
Summary of the invention
The object of the invention is to: provide a kind of high precision anti-blocking flowmeter, measuring accuracy is high, is lifted at Industry Control ability under rugged surroundings, reduces maintenance cost.
Technical solution of the present invention is: this flowmeter comprises the pressure short tube, upper assembly body, lower assembly body, web member, the negative terminal probe, anode probe and base, the top installation connecting element of base, lower assembly body is installed in the top of web member, establish two expansion chambers on lower assembly body, the negative terminal probe, the anode probe is arranged on web member, the negative terminal probe, the top of anode probe is communicated with respectively expansion chamber, the negative terminal probe, in the hypomere inserted base of anode probe, the negative terminal probe, some pressure ports distribute on the hypomere of anode probe, on lower assembly body through screw, screw hole is installed the assembly body, in two mounting holes of upper assembly body, the pressure short tube is installed respectively, the mounting hole of upper assembly body connects the expansion chamber of lower assembly body, isolation diaphragm and O-ring seal are installed between mounting hole and expansion chamber, the anti-blocking flowmeter of whole formation high precision.
Wherein, the interior diameter of negative terminal probe, anode probe is greater than 32mm, and the diameter of pressure port is not less than 12mm.
Wherein, the band edge wing on the outer wall of anode probe.
The present invention has the following advantages:
1, the band edge wing on the outer wall of anode probe, greatly increase and meet atmidometer, improved between probe and measured differential pressure, expanded measurement lower limit, improves measuring accuracy.
2, the some pressure ports of distribution on the hypomere of negative terminal probe, anode probe, the multiple spot pressure, every flow laminar flow amount state in the actual response pipeline, the flow measurement precision improves greatly.
3, the interior diameter of negative terminal probe 12, anode probe 13 is greater than 32mm, and the diameter of pressure port 11 is not less than 12mm, effectively avoids particulates plug, and blocking-proof result is good.
4, establish expansion chamber in lower assembly, gas is through out-of-date, and it is large that inner space becomes suddenly, and the particle of certain mass is dropped, and most of particle can not rise to upper space, guarantees that upper air is clean, and signal is good, Measurement sensibility.
5, between mounting hole and expansion chamber, isolation diaphragm is installed, intercepted by diaphragm when the minority fines arrive diaphragm, can't enter the rear portion pressure pipe, guarantee rear portion pressure pipe cleaning, make differential pressure transmitter, stop valve and pipeline thereof dirty never, guarantee to measure precision.
6, between mounting hole and expansion chamber, O-ring seal is installed, O-ring seal reduces to leak to be affected measuring system.
7, adopt multiple antiblocking design, be adapted at being widely used in the industrial gasses measuring system, Measurement sensibility is good, measures applied range, cancels loaded down with trivial details purging system, good economy performance.
8, adopt plug-in installation, be adapted at using in industrial heavy caliber pipeline system, its installation is workable, and installation period is short, and easy access greatly reduce the system maintenance cost, and execute-in-place is strong.
