Abstract
The invention provides a plastic tube rotor flow meter and an installing method. The plastic tube rotor flow meter is a device for calculating flow by measuring a rotating part arranged in a direct current pipeline, and is one of variable area type flow meters. A plastic tube rotor magnetic flow meter used in the past has the defects of being high in price, complex in structure, unreliable in measurement, large in pressure loss and the like. The plastic tube rotor flow meter comprises a connecting tube (1), wherein the connecting tube is connected with a nut (2), the nut is connected with an O-shaped seal ring (3), the seal ring is connected with an upper stopping piece (4), the upper stopping piece, the nut and the O-shaped seal ring are connected with a conical tube (5), and a floater (6) is arranged inside the conical tube and is connected with a lower stopping piece (7). The plastic tube rotor flow meter is used for measuring fluid flow.
Description
technical field:
the present invention relates to a kind of plastic tube spinner-type flowmeter and measure installation method.
background technology:
plastic rotor flowmeter is real is located at by measurement the device that rotatable parts in direct current pipeline are calculated flow, is a kind of of variable area formula flowmeter, still, the plastic tube rotor magnetic flowmeter price using at present, complex structure, the defect such as it is unreliable to measure, and the pressure loss is large.
summary of the invention:
the object of this invention is to provide a kind of plastic tube spinner-type flowmeter and installation method.
above-mentioned object realizes by following technical scheme:
a kind of plastic tube spinner-type flowmeter, its composition comprises: take over, described adapter is connected with nut, described nut is connected with O RunddichtringO, described O-ring seal is connected with upper backstop, described upper backstop, described nut, described O RunddichtringO are connected with canalis spinalis respectively, float is housed in described canalis spinalis and is connected with lower backstop.
described plastic tube spinner-type flowmeter, described canalis spinalis is made by ABS or AS plastics, and with scale.
a measurement installation method for spinner-type flowmeter, the method comprises the steps:
(1) plastic tube spinner-type flowmeter directly inserts bonding connection or flange connection;
(2) be vertically mounted on pipeline, leave space around and be convenient to install, angle of inclination should be less than 5 °;
(3) on flowmeter upstream position, should there is the straight length of five times of flowmeter bore length, to guarantee the stable correctly operation of instrument;
(4) whether answer before using somascope tabular value scope to conform to institute survey scope, the maximum instantaneous flow of measured medium, the pressure and temperature of measured medium should be in the allowed band of flowmeter if should be less than flowmeter survey t and hindering.
(5) while using, as found Taper Pipe sealing place seepage, with being wrenched nut, as seepage still, change seal.
beneficial effect:
1. the present invention is in a vertical Taper Pipe expanding from bottom to top, float in Taper Pipe owing to moving up and down under flow velocity and buoyancy, after float weight balance, by magnetic coupling, pass to and index dial indication flow, spinner-type flowmeter is a kind of variable area flow instrument.
the present invention it there is the features such as simple in structure, cheap, directly perceived, the pressure loss is little, highly versatile, easy to maintenance.
3. the present invention is applicable to measure by the low discharge of pipe diameter D<150mm, and sectional metering, measurement range are flexible, can micrometer laugh at flow, survey body material various, can survey Korrosionsmedium, DN10 bore is with variable valve below, facilitates user.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.
