Orifice meter scale deformation analysis of the reasons

Abstract: the analysis of the causes of orifice meter scale deformation information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Orifice meter belongs to the old grandparents in the measuring instrument, because of its low cost, using the characteristics of convenient installation won the majority of customers. So the limitation of itself principle and production technology, environmental change in the operating conditions of bad deformation would happen in the future. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the cause of the orifice meter scale deformation analysis for details. Orifice meter belongs to the old grandparents in the measuring instrument, because of its low cost, using the characteristics of convenient installation won the majority of customers. Principle and the limitation of the craft that make, so itself after the environment is bad working condition of deformation would happen, flowmeter technology below small make up for this like now, for everyone to do analysis, for reference: first, the analysis of the causes of orifice plate deformation after the orifice plate deformation is due to heat expansion, orifice diameter and the gap between the ring chamber, orifice plate continues to swell when unable to expand in the direction of outer diameter, then in the orifice plate under the action of differential pressure on either side, produce the export side bulge deformation. Investigating the scene of orifice plate deformation, is often found associated with clues. 1. Associated with the throttle device of poor heat insulation. Insulation good throttling device does not appear leakage phenomenon. 2. Associated with the weather. The throttle device was no leakage phenomenon, due to the cold weather, the winds blow, plus or minus leakage ring chamber attaches. 3. Associated with positive and negative annulus junction leakage. Unable to eliminate leakage, using the method of screw bolt and remove the throttling device replacement of sealing gasket, and then found the orifice plate deformation. To the above clues of reasoning orifice plate deformation reason analysis. When the throttle device design calculation, orifice diameter and the ring chamber with the gap is big enough to stay is assuming the same orifice plate and ring room temperature, but in fact can't be the same, orifice was surrounded by a ring chamber, and has a high temperature fluid to provide heat, so the temperature is high, the full expansion. Contact with liquid and ring indoor circle, but contact with the atmosphere, the cylindrical and external environment factors such as temperature, make its temperature drops too low, leading to the reserved clearance, cause the orifice plate deformation. Orifice plate deformation and plus or minus leakage associated annulus place, if it weren't for sealing gasket damage caused by leakage, it is just because of the orifice plate deformation, which resulted in increased clearance between positive and negative annulus after sealing gasket and annulus between cracks. 2, orifice plate deformation solution after find the root cause of the orifice plate deformation, prevention of orifice plate deformation has a simple and effective method, namely the design and calculation, considering the ring room temperature may be orifice that are lower than actual situation, reasonably calculate the gap. Calculation ring round outdoor temperature should not be higher than 100 ℃. Therefore, when the customer selection will communicate and manufacturer, put all the bad factors are taken into account. Flow meter manufacturer as speed meter and positive displacement meter, differential pressure meter, area meter professional manufacturer, has always insisted on developing new technology, new products. Summarize the experiences of years production practice, the positive communication flow field at home and abroad, working to develop a variety of flow measurement products, forming scale, systematic and diversified pattern of production. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
