Abstract
The utility model relates to a U-shaped flow tube of a mass flow meter, which relates to the flow tube of a mass flow meter, needs to overcome the defect of the tube type of the mass flow meter, and provides a flow tube that the structure is simplified and the sensitivity is high. The technical proposal of the utility model adopts two flow tubes which connect diversion fluid, each flow tube is characterized in that the flow tube is bent and made into a U-shaped tube; and a long circular damping plate is inserted and arranged at the leg-part tube-wall cylindrical surface of the U-shaped tube. The utility model is used for the U-shaped tube of the mass flow meter.
Description
Technical field:
The utility model relates to the flowtube that is used for mass flowmeter.
Background technology
The mass flowmeter cast is of a great variety, and various tubular differing from one another, especially small-bore flowtube is variation especially.But existing mass flowmeter cast is caught outside precision, stability, vibration and is also had shortcoming.It is little that an actor's rendering of an operatic tune that has cuts the shape diameter, and an actor's rendering of an operatic tune core ruptures easily in the smart casting, causes waste product; The cast that has has a plurality of corners to cause branch fluid an actor's rendering of an operatic tune complex structure, tubular complexity, be difficult to make the tubular of stable and consistent, it is low to bend precision, when flowtube combines with the branch fluid, for realizing that two pipe consistance need be matched, the school is tubular, through tubular alignment, can increase stress to flowtube, influence the flowtube operating characteristic of mass flowmeter, cause the precision instability.In order to improve the amplitude that sensitivity have to the enlargement discharge pipe, thereby it is difficult to eliminate the vibration unofficial biography, influences precision again.More difficult high precision of trying to achieve 0.1 grade.
The utility model content
The purpose of this utility model is the shortcoming that overcomes on the mass flowmeter cast, and a kind of designs simplification, highly sensitive flowtube are provided.
The technical solution of the utility model adopts two to connect the flowtube of dividing fluid, it is characterized in that flowtube is bent into U type pipe; The foot tube wall face of cylinder on U type pipe both sides studs with oblong damping sheet.
The utility model provides U type pipe can reach 0.1 grade of precision, and zero point drift is stable; Damping sheet on U type pipe, anti-extraneous vibration interference performance is strong.Can be used for the high precision mass flowmeter.
Description of drawings
What Fig. 1 represented is structural drawing of the present utility model.
Fig. 2 is the cast figure of U type pipe.
Embodiment
The utility model (see figure 1) adopts two to connect the flowtube 1,2 of dividing fluid 4,5, and flowtube 1,2 is bent into U type pipe, and overlaps the damping sheet 3 of 4 block length circles, the damping sheet of promptly every limit 2 block length circles at foot's tube wall face of cylinder edge of U type pipe 1,2.
Fluid is through dividing fluid 4, U type pipe 1,2 to dividing fluid 5, the vibration of the location arrangements damping flowtube effectively of four damping sheets 3, the vibration that makes the branch fluid is zero, also make extraneous vibration disturb to be not easy to pass to pay and encourage the systematic influence measuring accuracy, overcome the Bourdon tube effect, the negative sense deviation that produces overcomes influence raising precision and repeatability that pressure changes.
Claims (2)
1. mass flowmeter U type flowtube adopts two to connect the flowtube of dividing fluid, it is characterized in that flowtube is bent into U type pipe; The foot tube wall face of cylinder on U type pipe both sides studs with oblong damping sheet.
2. mass flowmeter U type flowtube according to claim 1 is characterized in that the Long Circle damping sheet at U type pin portion tube wall face of cylinder edge cover is 4, the circular damping sheet of promptly every limit 2 block lengths.
