The classification of the throttle device

Abstract: the classification of the throttle device information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. The throttle device has simple structure, easy installation, reliable operation, low cost, convenient maintenance, wide range of selection, Standard section device measuring diameter from 50 mm to 1200 mm, non-standard throttling device applicable pipe diameter can be as small as 6 mm, 3000 mm; Measure the temperature. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the classification of the throttle device article details. The throttle device has simple structure, easy installation, reliable operation, low cost, convenient maintenance, wide range of selection, Standard section device measuring diameter from 50 mm to 1200 mm, non-standard throttling device applicable pipe diameter can be as small as 6 mm, 3000 mm; Measuring temperature can be as high as 555 ℃; Pressure can be up to 42 mpa) , and also has the advantages of without the need for a separate calibration standard throttle device, is zui widely applied in flow meter, zui mature one kind of product, therefore widely used in electric power, chemical industry, metallurgy, petroleum, textile, military and other fields. Orifice plate is refers to the key parts of the throttle device - - - Throttling, because it is a piece of perforated metal plate, so its name. After a long time, the whole throttling device is also known as orifice plate, also known as the differential pressure type flowmeter for the orifice plate. Throttling device is measuring the flow of differential pressure sensitive element. Cooperate with differential pressure transmitter and reality, records, integrating and adjust instrument, can be used to measure, integrating, and control of liquid, steam and gas instantaneous flow and cumulative flow. Throttling device through throttling and pressure device ( Including take pressure, bring pressure tube and valve, etc. ) , form a complete set of flange, sometimes including standard straight pipe before and after. Standard throttle device has standard orifice, venturi nozzle, standard. The standard orifice plate by way of pressure points Angle joint ( Ring room or drilling) Take the pressure, the pressure and diameter of the flange, Standard nozzle according to the form of points ISA1932 nozzles, the length to diameter nozzle; Standard according to the form of venturi tube nothing venturi nozzle, venturi tube ( Rough casting or machining or plate) 。 Non-standard throttling devices have small orifice, 1/4 round orifice, round orifice, segmental orifice, eccentric orifice plate, double orifice, built-in orifice, conical inlet orifice plate, etc. Other forms of throttling device with pitot tube, velocity-equalizing tube, wedge, cone, etc. , orifice flow meter is the standard term throttling device, belongs to differential pressure type flowmeter in zui commonly used one. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
