Description
Technical field
The utility model belongs to sensor technical field, is related to a kind of shell of sensor, specifically a kind of coriolis force matter
Measure flow sensor shell.
Background technology
Coriolis flow sensor is the primary device of Coriolis flowmeter, is that flow signal is converted to electricity
The device of signal.Coriolis flow sensor belongs to resonant transducer, working condition be with dielectric property not
It is vibrated under some specific frequency together, shell is an important component of sensor, and shell is disturbed can if vibration is generated
The stability of sensor vibration is influenced, so as to cause the decline of sensor element precision.At present, Coriolis flow sensor
Shell be largely divided into two major class, one kind is box, and one kind is cast, and the shell of cast is usually by symmetrical two halves to weldering of getting up
It connects, section majority is rounded, and the sensor measurement tube shape that the shape of entire shell is corresponding is similar, as measurement pipe is
U-shaped, shell is also U-shaped, shapes mode or uses mold one-pass molding, die cost is costly or divides
Section butt welding, the complex process of welding, welding process middle casing are easily deformed, and welding quality is difficult to ensure that, and when sensor is sent out
During raw failure, open that casing tech is also complicated, and maintenance cost is high；And the manufacturing process of another kind of Box-type enclosures and dismounting are all relatively simple
Single, cost is much lower, but there are enclosure volume is big, surface area is also big, easily by the vibration interference of external environment, so as to shadow
Ring the measuring accuracy to sensor.
Utility model content
It is simpler that the purpose of this utility model is just to provide a kind of structure, interference free performance preferably Coriolis stream
Quantity sensor shell.
Used technical solution is the utility model to achieve these goals：A kind of Coriolis flow sensor
Shell, including top plate and side plate, the top plate is the curved surface in undaform, and curved surface is related with the shape of sensor measuring tube, tool
Body is made of two planes of one section of great circle cambered surface and left and right, is connected between plane and great circle cambered surface by a small arc surface, top plate
Side is symmetrily processed with the tenon of multiple protrusions, and the both ends of top plate are bent downwardly and are equipped with circular arc, and the side plate can be plane,
It can also be machined with muscle of different shapes in the plane, the top edge shape of side plate is matched with the curve form size of top plate,
Side plate top edge is symmetrily processed with multiple tongue-and-grooves corresponding with the top plate tenon；
The side plate can be plane, can also suppress muscle in the plane, and the muscle of reasonable design can further improve
The interference free performance of shell；The muscle is in simple geometric figure, preferred arrow-shaped, "-" type, two fonts, cross, round,
Trapezoidal and diamond shape.On the one hand arrow-shaped muscle plays muscle, on the other hand also can indicate that the flow direction of medium, housing combination is good
Afterwards, the arrow on two blocks of side plates should be directed toward unanimously.
The beneficial effects of the utility model are：Compared to ordinary rectangular, trapezoidal Box-type enclosures, structure is simpler, internal
Space is small, good in anti-interference performance, easy to maintenance, cost performance is more superior.

Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings
A kind of Coriolis flow sensor shell, as shown in Figure 1, including top plate 1 and side plate 2, top plate 1 is curved
Shape, as shown in Fig. 2, the curved surface is related with the shape of sensor measuring tube, it is specifically flat by one section of great circle cambered surface and left and right two
Face forms, and is connected between plane and great circle cambered surface by a small arc surface, the side of top plate 1 is symmetrily processed with the tenon of multiple protrusions
3, the end flat of top plate 1 is bent downwardly and is equipped with circular arc 4, and circular arc 4 with sensor main body for being connected, and side plate 2 is plane, such as
Shown in Fig. 3, front and rear two pieces of side plate shape and size are identical, and muscle 5 of different shapes, the top of side plate 2 can also be machined in plane
Portion's edge shape is matched with the curve form size of top plate 1, and 2 top edge of side plate is symmetrily processed with multiple right with 1 tenon 3 of top plate
The tongue-and-groove 6 answered；The height of tenon 3 and the depth dimensions of tongue-and-groove 6 are corresponding with outer casing thickness, the Tenon that tenon 3 and tongue-and-groove 6 form
Structure can be used for the integrated positioning between sheath top plate and side plate, facilitate the welding of entire shell.
Side plate 2 can be plane, can also suppress muscle of different shapes in the plane, and muscle 5 can be protrusion, also may be used
Can be in various simple geometric figures to be recessed, as shown in figure 4, arrow-shaped can be selected, "-" type, two fonts, ten
Font, circle, trapezoidal and diamond shape etc..If using arrow-shaped muscle, by the direction of arrow and quality stream when being assembled to shell
Medium flow direction in quantity sensor is consistent, and is on the one hand played the role of muscle, is increased interference free performance, on the other hand can be with
It indicates the flow direction of medium, facilitates the installation and maintenance of sensor.
