进口文特流量计-美国阿卡迪亚品牌

进口文特流量计Product description:

It includes upstream flanged straight pipe, downstream flanged straight pipe and throttling device. The upstream flanged straight pipe and the downstream flanged straight pipe have grooves matching the throttling device. The upstream flanged straight pipe and the downstream flanged straight pipe clamp the throttling device and fix it with studs. The throttling device is a multi hole throttling device, with a central hole in the middle and a plurality of annular holes arranged around the central hole. The center hole and annular hole shall be chamfered upstream and downstream, the upstream shall be filleted, and the downstream shall be chamfered at right angles. The pressure tap of the upstream flanged straight pipe is taken as the upstream pressure, and the pressure tap in the middle of the throttling device is taken as the throat pressure of the middle hole. The middle hole and annular hole are chamfered upstream and downstream to reduce wear and eddy current formation and reduce pressure loss. At the same time, the multi holes disperse the force, improve the range ratio, measurement accuracy and stability, and have a wide range of applications, which is conducive to promotion and popularization.

进口文特流量计Working principle: When using, first fix the throttle plate in the groove between the upstream flanged straight pipe and the downstream flanged straight pipe by using double headed studs and nuts, and the upstream arc chamfer of the throttling device faces the upstream flanged straight pipe. The pressure difference is obtained by taking the upstream pressure of the throttling device and the throat pressure of the throttling device through the first pressure tap and the second pressure tap. The central hole and annular hole on the throttle plate can disperse the force, reduce wear and eddy current formation, reduce the pressure loss, achieve rectification and reduce the pressure loss, and have low requirements on the straight pipe section, improve the range ratio, measurement accuracy and stability. The device is simple and reasonable in structure design, easy to operate, easy to disassemble and assemble. While obtaining a stable differential pressure value, it greatly reduces the installation requirements for the straight pipe section, and is safe and stable, Wide application scope.

进口文特流量计Principle:

One end of the upstream flanged straight pipe and the downstream flanged straight pipe is provided with a groove, the inner diameter of the groove is the same as the outer diameter of the throttling device, and the bottom of the groove is pasted with a sealing gasket. The groove plays a positioning role to ensure that the throttling device is in the center of the pipe. The sealing gasket can improve the tightness of the throttling device and the pipeline.
