Description
Technical field
the utility model relates to flow sensor, is specifically related to a kind of pressure type flow quantity sensor.
Background technology
Along with flow measurement technology development and commercial production are for the requirement of flow measurement precision, more and more require in industrial processes accurately to control, so require that flow sensor is effectively measured industrial link.We all will coordinate Traditional differential pressure instrument first to measure differential pressure for restriction device measuring system in commercial production link now, then by calculating data on flows.But in actual use, for various reasons, often cause measuring system can not effectively continuous coverage, or measuring accuracy be poor, effectively can not participate in industrial automation system and control, and maintenance cost is high.
Summary of the invention
the purpose of this utility model is: provide a kind of pressure type flow quantity sensor, throttling probe adopts diamond structure, measuring accuracy is high, the pressure loss is little, easy for installation, promote its industrialization flow measurement ability, reduce maintenance cost, reduce energy loss simultaneously, meet industrial measurement and control product power conservation requirement.
Technical solution of the present utility model is: this flow sensor comprises pressure responsive element, throttling is popped one's head in, mounting seat, measure cylindrical shell, joint flange and converter, the two ends measuring cylindrical shell are welded to connect flange respectively, measure the tube wall opening welded and installed base of cylindrical shell, throttling probe sheath Upper gasket inserts from mounting seat to be measured in cylindrical shell, the bottom of connecting link is through installing only head, traveling nut is fixed in mounting seat, the top mounting converter of connecting link, what throttling was popped one's head in meets out the pressure assembly chamber that end opens lateral direction penetrating, setting pressure sensing element in pressure assembly chamber, pressure responsive element is by the sealing gasket of both sides, pressure cap screw is fixed in throttling probe, the connecting line of pressure responsive element is drawn out to converter from throttling probe interstitial hole, overall formation pressure type flow quantity sensor.
Wherein, throttling probe is rhombus cylinder.
Wherein, installation direction mark on connecting link.
The utility model has the following advantages:
1, throttling probe adopts diamond structure, can produce stable differential pressure signal, and its flow pressure loss is simultaneously low, and energy-saving effect is obvious, and its energy loss is only orifice throttle part 1/10.
2, the probe internally provided pressure responsive element of throttling, pressure survey is sensitive, measuring accuracy and security high, avoid due to install connecting pipe cause measuring error and dielectric leakage problem, long-time stability are good.
3, pressure measuring element is arranged in throttling probe, avoids medium to enter probe inner, some particle accumulation can be avoided like this to pop one's head in inner, and cause probe blocking, blocking-proof result is obvious.
4, due to integrative installation technology, avoid conventional on-site pipeline to weld the impact of measurement restricting element, it is convenient to install with maintenance safety, avoids the dismounting of conventional throttle device to bother.
5, all install O-ring seal between assembly, O-ring seal reduces dielectric leakage, improves system cloud gray model security.
6, adopt multiple antiblocking to design, be adapted at widely using in industrial gasses measuring system, Measurement sensibility is good, measures applied range, cancels loaded down with trivial details purging system, good economy performance.
7, adopt plug-in installation, be adapted at using in industrial heavy caliber pipe system, workable, installation period is short, easy access, greatly reduces system maintenance cost.
