Description
Technical field
The present invention relates to flowmeter, say it is a kind of conical body pressure tapping flowmeter in detail.
Background technology
We know, existing flowmeter is to be provided with the circular ring type pressure vessel on internal diameter of the pipeline, circular ring type pressure vessel inboard is an acute angle, and the circular ring type pressure vessel is provided with negative pressure pipe, and negative pressure pipe the place ahead is provided with the pressure pipe of officiallying enroll, the pressure pipe of officiallying enroll is connected differential pressure transmitter with negative pressure pipe, with the Fluid Computation flow.This flowmeter, owing on internal diameter of the pipeline, be provided with the circular ring type pressure vessel, the endless belt blocking pipe of circular ring type pressure vessel, the big flow of the resistance of ducting is low, and the pressure loss is big, and efficient is low, and energy consumption is big, the use cost height; Owing on internal diameter of the pipeline, be provided with the circular ring type pressure vessel, flow of liquid is when the circular ring type pressure vessel, and foreign material easily are deposited on the ring belt and tube wall of circular ring type pressure vessel, and positive and negative pressure pipe can not obtain true definite pressure differential, the efflux coefficient poor stability, it is big to measure inaccurate error; Owing on internal diameter of the pipeline, be provided with the circular ring type pressure vessel, efflux coefficient poor stability, the straight length that need before and after the circular ring type pressure vessel, extend, manufacturing cost height; Be acute angle because the circular ring type pressure vessel is inboard, easy to wear, it is big to measure inaccurate error.
Summary of the invention
The technical matters that the present invention solves is, it is low to solve the big flow of the resistance of ducting, and the pressure loss is big, efficient is low, and energy consumption is big, the efflux coefficient poor stability, it is big to measure inaccurate error, and the problem that manufacturing cost and use cost is high provides a kind of resistance of ducting low discharge height, the pressure loss is little, the efficient height, energy consumption is little, and efflux coefficient stability is high, the measuring accuracy height, the conical body pressure tapping flowmeter that manufacturing cost and use cost is low.
Technical scheme of the present invention is, pressure vessel is provided with negative pressure pipe, and negative pressure pipe the place ahead is provided with the pressure pipe of officiallying enroll, and the pressure pipe of officiallying enroll is connected differential pressure transmitter with negative pressure pipe, and the primary structure characteristics are, the pressure vessel front side is a cone, and the pressure vessel rear side is the frustum of a cone.
As its improvement, the pressure vessel center is provided with pressure port, and pressure port connects negative pressure pipe.
The pressure vessel outside is provided with stabilizing feed well, and pressure vessel is fixed in the stabilizing feed well, and stabilizing feed well is provided with officially enroll pressure pipe and negative pressure pipe.
The invention has the beneficial effects as follows that because the pressure vessel front side is a cone, the pressure vessel rear side is the frustum of a cone, the current stabilization performance is good, resistance of ducting low discharge height, the pressure loss is little, the efficient height, energy consumption is little, efflux coefficient stability is high, the measuring accuracy height, and manufacturing cost and use cost is low.The present invention is applicable to the flow of measuring various fluid media (medium)s, is specially adapted to measure the dirty medium of various high temperature, impure, easy crystallization, as coke-oven gas, blast furnace gas etc.
