Flowmeter orifice flowmeter can be OEM manufacturers better sales of gas liquid flow meter

BYM-BK standard orifice plate outline standard can be used to measure the pipeline liquid, gas, steam flow. Standard plate by GB GB / T2624-93 design and manufacturing, according to GB JJG640-94 checks. Standard Orifice can corner tapping (including Central Office to take pressure), flange pressure or D-D / 2 to take pressure three kinds of ways to take pressure. Conducted according to the national standard design, manufacture and test of standard orifice without actual flow calibration, high precision, simple structure, low manufacturing cost, but the pressure loss in all standard throttling device maximum does not apply to the required pressure loss is small, Standard Orifice widely used in petroleum, chemical, metallurgy, electric power and other industries. Scope 1. nominal diameter: 50 mm ≤DN≤1200mm as DN> 1200 mm, for an actual flow calibration 2. aperture ratio β: 0.20≤β≤0.75 3. Reynolds number range: When 0.20≤β≤0.45 time, 5000≤ ReD when 0.45≤β≤0.75 time, 10000≤ReD 4. Nominal pressure: PN≤16MPa 5. Accuracy: a structure 1, corner tapping mode. 2, the flange pressure mode. 3, D-D / 2. Installation Requirements 1. Installation should ensure the central orifice, flange axis concentric pipe axis and gaskets, misalignment may not exceed 0.002D / β. 2. The orifice of the positive and negative directions, upstream and downstream flange to take pressure medium flow should be consistent, to take pressure hole orientation may be determined according to different media and installation of the transmitter. 3. throttle device and pipe connections, end face of the pipe axis is not perpendicular to the weld must not be greater than 1o, internal seam welding should be processed to make it smooth, without burr and slag. 4. Take the pressure flange and pipe welding before, should first take pressure on the pipe drilled holes the same diameter of the aperture and take pressure flange to take pressure on its, take pressure tap and pressure pipe flange welding take pressure holes aligned. 5. Optional bring downstream straight pipe. 6. D-D / 2 is a complete set of delivery to take pressure flange connection can be installed directly.
