Throttling Devices

throttling device, also known as differential pressure flowmeter, Orifice flowmeter contains (integrated orifice flow meter, standard orifice, annular orifice flow meter, integrated annular orifice flow meter) V-cone flowmeter can be divided according to function name gas flow meter, flue gas meter, steam flow meter, gas flow meter, compressed air flow meter, liquid flow meter. V cone flowmeter (V - coneflowmeter) is put forward in the 1980 s a novel differential pressure flowmeter, compared with the ordinary throttle body, it changes the throttling layout, from the center hole throttle annular throttle instead. Long-term use, V cone flowmeter compared with general differential pressure flowmeter, high precision, good repeatability and long-term by the installation condition of limited small, wear resistance, wide measuring range, suitable for smudgy medium, small pressure loss, etc. More because of the v-shaped cone itself as the flow field of the rectifier and become a new type has unique properties of excellent flowmeter. V cone flowmeter is a coaxial installed in the measuring tube tip of the cone as the throttle a new differential pressure type flow measuring devices, it is a kind of based on venturi tube measurement principle, and collection of classical venturi tube, circular orifice and wear-resistant orifice advantages in the integration of new type of throttling device. Short straight pipe upstream and downstream demand: straight pipe upstream of the shortest length is 3 d, (3 d) on the downstream side of the valve installation requirements, downstream straight pipe length for 3 d or less. Accuracy: + / - 0.5%; Repeatability is 0.1%; A routine than 15:1. The pressure loss of the resistance to dirt, small. With the adjusting of the flow and the fluid mixing action. Convenient installation, is the technical renovation of the ideal flowmeter; Free maintenance, the workload is very small. Short straight pipe before and after the request, generally only 0 to 3 d, upstream downstream only 0 to 1 d. Loss of pressure is small, only 1/2 - one-third of orifice plate. Close to the venturi tube V cone trailing edge to produce small vortex, the differential output stability, small fluctuations. Without sundry stagnation, by cone thoroughly purge type design. Throttling area of long-term stability, signal stability.
