孔板流量计orifice plate flowmeter原理principle:流体通过节流件时产生压差,结合测量的压力、温度来计算流量。The fluid flow rate is calculated by combining the measured pressure and temperature.优点merit:坚固耐用,性能可靠,维修方便,按标准制造Durable, reliable performance, easy maintenance, according to standard...
2) orifice plate 节流孔板 1. To solve the problem of pipes vibration of large-sized compressor in ammonia plant,orifice plates are installed after thorough analysis of the causes of vibration, effectively solved the problem. 针对合成氨系统的大型压缩机组管系振动问题,深入分析了原因后,采取在管道中...
The operating principle of eyc-tech P064 differential pressure transmitter is based on the airflow forms a local contraction at the orifice plate, so the flow velocity increases and the static pressure decreases, so a pressure difference is generated in front or at the back of the orifice pla...
In 1874, Duplay described the tubularization of the urethral plate distal to the urethral orifice. His first successful hypospadias repair with this technique was achieved in five stages. In 1880, Duplay observed the capacity of the urethral plate to tubularize over a catheter. He wrote: "...
detection part of wedge-shaped flowmeter is wedge-shaped orifice plate; it is a V-shapedthrottling element, and its round angelus parietal is adown, which in favor of avoidingviscous flowat upstream ofthrottling elementwhen fluid withsuspended particle(powder, silt and other ...
(2) Pulse type: Since the condensed water of different temperatures passes through the two-pole series orifice plate type, the different pressures between the two-pole orifice plate shape act to drive the valve flap to move. The working principle of the hydrophobic valve: ...
The result is a high pressure upstream and a low pressure downstream that is proportional to the square of the flow velocity. The disadvantage of an orifice plate is it usually produces a greater overall pressure loss than other differential pressure devices. An advantage of this device is that...

“the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops.” Put simply, if fluid flows past a solid object, it keeps flowing along that surface (even ...
pressure the diaphragm d will move the balance lever e so as to open the orifice f6 or close it, as the case may be, to an extent sufficient to create a pressure differential on the piston sections /', 2 and thereby bring about movement of the piston in one direction or the other. ...
