Description
Technical field
The utility model relates to a kind of Coriolis flowmeter, particularly relates to a kind of Coriolis mass flowmeter sensor.
Background technology
Coriolis mass flowmeters is called for short Coriolis flowmeter, and it a kind ofly utilizes fluid flow in vibrating tube and produce the principle of the Coriolis force be directly proportional to the mass rate instrument of direct measurement quality flow; Measure because it can realize high precision direct flow truly, and have resistance to wear, anticorrosive, the plurality of advantages such as medium and multiple parameters can be measured, be now widely used in petrochemical complex, pharmacy, food and other industrial processs.
The main body of existing double-U-shaped shunting Coriolis flowmeter is generally by shunt, two single u-shaped measuring tubes and two flange compositions, prior art is in the timing of manufacture aforementioned double-U-shaped shunting Coriolis flow, main employing welding technology, wherein, shunt self adopts polylith plate body to be welded, shunt, also welding technology is all adopted to connect between U-shaped measuring tube and flange, Problems existing is: welding technology is troublesome poeration not only, and inevitably there is welding deformation due to during welding, and there is negative effect in welding deformation flow meter performance, and along with the increase of welding position, the influence degree of welding deformation is also more serious.
Utility model content
For the problem in background technology, the utility model proposes a kind of Coriolis mass flowmeter sensor, comprise shunt, two single u-shaped measuring tubes and two flanges, described two single u-shaped measuring tubes are arranged on the upper side of shunt parallel to each other, two flanges are arranged at the left and right sides of shunt respectively, and its improvement is: described shunt housing adopts casting technique one-body molded.
Principle of the present utility model is: in prior art, shunt self adopts polylith plate body to be welded, not only complex process, and welding deformation during welding can cause shunt inner cavity size off-design size, affect the measuring accuracy of flowmeter, the problem of dimensional discrepancy is brought in order to solve welding deformation, the utility model adopts casting technique to make shunt, this just effectively can reduce the welding position on shunt, thus the negative effect that minimizing welding deformation of trying one's best brings, improve the measuring accuracy of flowmeter.
For the ease of installing location, the utility model has also done following improvement: the upper side of described shunt is provided with four intubate, four rectangular distributions of intubate, two single u-shaped measuring tubes are plugged in four intubate parallel to each other, and U-shaped measuring tube and intubate are welded and fixed.After adopting this improvement project, before U-shaped measuring tube and shunt are fixed, utilize the supporting role of intubate, U-shaped measuring tube can be plugged on the corresponding position on shunt exactly, facilitate the positioning action between U-shaped measuring tube and shunt greatly, simultaneously, U-shaped measuring tube is welded by intubate, weld part from shunt relatively away from, welding high temperature can be avoided to impact shunt, and due to the surface of contact of U-shaped measuring tube and intubate better, make the connective stability between U-shaped measuring tube and shunt better.
Preferably, described flange adopts welding technology to be welded on shunt.During due to casting shunt, need to reserve running channel for casting stream is dynamic, and pore size between flange and shunt is relatively large, so inventor is not by shunt and flange integrally casting; Although still adopt welding technology to connect between flange and shunt, but because the connecting tube between flange and shunt is relatively long, can when casting shunt, also cast out the connecting portion of certain length in the shunt left and right sides simultaneously, this just can make flange welding portion away from shunt inner chamber, flange welding is operated less on the impact of shunt body.
Preferably, the gage beam of described U-shaped measuring tube both sides is respectively provided with an electromagnetic detector; The top of described U-shaped measuring tube is provided with electromagnetic driver.
Preferably, the plugging position of described intubate and U-shaped measuring tube is provided with hermetically-sealed construction.
Advantageous Effects of the present utility model is: effectively can reduce the welding position in flowmeter manufacturing process, and the negative effect avoiding welding deformation to bring, also simplify the assembly manipulation of flowmeter simultaneously.
