Abstract
The utility model provides a taper pipe for a metal pipe floater flowmeter. The taper pipe is characterized in that the taper pipe comprises a taper pipe cavity; the diameter of the small diameter end of the taper pipe cavity is R which is not less than 15 mm and not more than 85 mm; the axial length of the taper pipe cavity is L which is not less than 50 mm and not more than 60 mm; and the taper angle of the taper pipe cavity is alpha which is not less than 3 degrees and not more than 28 degrees. According to the taper pipe provided by the utility model, the axial length of the taper pipe cavity is increased to 50-60 mm, and the taper angle of the taper pipe cavity is reduced to 0.3-28 degrees, so that the traveling distance of a floater in the taper pipe can be lengthened and the fluid turbulivity is reduced after the floater of the metal pipe floater flowmeter is arranged in the taper pipe cavity of the taper pipe, therefore the stability and linearity of floater motion are improved, and the measurement precision is guaranteed.
Description
Technical field
The utility model relates to a kind of metal pipe float flow meter, relates in particular to a kind of Taper Pipe of metal pipe float flow meter.
Background technology
Metal pipe float flow meter is to utilize the variable area type measuring principle, is used for the volumetric flow rate of the liquids and gases of continuous coverage closed conduct.It is to utilize the kinetic energy of fluid to detect flow, does not need external impetus.The measurement body of suspended body flowmeter is made up of with the float that axially moves freely along Taper Pipe a vertical Taper Pipe and that enlarges from bottom to top only.Float institute is stressed to be constant, and the annulus area between float and the Taper Pipe moves along with float and changes.Therefore in Taper Pipe, get height through measuring float, can extrapolate the flow that passes through in the pipeline.When the float in the Taper Pipe moved up and down, the magnetic coupled system drive pointer rotation that drives in the converter was read corresponding flow value through index dial and pointer then.The measuring accuracy of existing metal pipe float flow meter can reach 1.0～1.5 grades; But have problems one be fluid in the taper tube chamber of metal pipe float flow meter through after repeatedly shrinking and expanding; Not only increased the pressure loss; And the enhancing of fluid turbulent degree, cause the suspended body flowmeter bad stability, the inconvenience of user's number of degrees; The 2nd, because twice reducing increased manufacture difficulty and cost cost.The 3rd, the cone angle of taper tube chamber is bigger, and when rate-of flow was big, the linearity of the float motion in the taper tube chamber caused measuring accuracy to reduce with regard to variation.
The utility model content
The technical matters that the utility model solves is: a kind of Taper Pipe of metal pipe float flow meter is provided, can increases the shift motion length of the float that is installed in the Taper Pipe, reduce the fluid turbulent degree.
The technical scheme of the utility model is: a kind of Taper Pipe of metal pipe float flow meter; It is characterized in that: said Taper Pipe has the taper tube chamber, and the diameter of the miner diameter end of said taper tube chamber is R, 15mm≤R≤85mm; The axial length of taper tube chamber is L; 50mm≤L≤60mm, the cone angle of taper tube chamber are α, 0.3 °≤α≤28 °.
The diameter R=15mm of the miner diameter end of said taper tube chamber, the axial length L=50mm of taper tube chamber, the cone angle of taper tube chamber=0.3 °.
The diameter R=85mm of the miner diameter end of said taper tube chamber, the axial length L=60mm of taper tube chamber, the cone angle of taper tube chamber=28 °.
The beneficial effect of the utility model is: the utility model is increased to 50mm～60mm through the axial length with the taper tube chamber; The cone angle of taper tube chamber is reduced to 0.3 °～28 °; After making that the float of metal pipe float flow meter is installed to the taper tube chamber of Taper Pipe, can prolong the stroke of float in Taper Pipe, reduce the fluid turbulent degree in the Taper Pipe; And then improve the stability and the linearity of float motion, guaranteed measuring accuracy.
