A V-cone flowmeter vertical installation structure

Abstract

A vertical installation structure of a V-cone flowmeter, including a high-pressure end condensation tank and a low-pressure end condensation tank respectively installed on the high-pressure end interface and the low-pressure end interface of the V-cone flowmeter, and the inlets of the high-pressure end condensation tank and the low-pressure end condensation tank are arranged The top of the side is level with the high-pressure end interface and the low-pressure end interface of the V-cone flowmeter respectively; the outlet at the same height as the inlet of the low-pressure end condensate tank is connected to a water storage tank, and the bottom of the water storage tank is opened and connected There are valves; the bottom outlet of the condensing tank at the high-pressure end and the condensing tank at the low-pressure end are connected to the input end of the differential pressure transmitter, and the output end of the differential pressure transmitter is connected to the input end of the flow calculator; it is also connected to the lower part of the high-pressure end interface of the V-cone flowmeter The thermal resistance temperature measuring element is also connected to the input end of the flow calculator; the invention solves the problem of liquid level change in the condensation tank caused by water vapor condensation by adding a water storage tank to drain the condensed water And the liquid level accumulation problem in the V-cone vertical pipe effectively enhances the applicability and accuracy of the V-cone flowmeter.

Description

technical field [0001] The invention relates to the technical field of V-cone flowmeters, in particular to a vertical installation structure of V-cone flowmeters. Background technique [0002] Although the differential pressure flowmeters represented by orifice plates, nozzles, venturi tubes and uniform velocity tubes have gone through a long development process, they have not solved the problems of low accuracy, narrow measurement range, easy wear, and on-site installation conditions. The requirements are high, and a series of problems such as mixed-phase flow and dirty flow cannot be measured. Experts are committed to the research and development of new differential pressure flow sensors to make up for the shortcomings of orifice plates, nozzles, Venturi tubes and uniform velocity tubes. V-cone flowmeters are among the best. It also uses the throttling effect to measure the flow rate. Compared with other throttling bodies, it changes the throttling layout, from the tradit...
