Abstract
The utility model relates to a vertical bending pipe shunting pressure flow meter used for measuring liquid flow. Consisting of a flanged bending pipe, a connecting pipe, a little flow meter, a U-shaped liquid return pipe, a liquid return straight pipe and an adjustable free joint. The utility model has the advantages of simple structure, low cost, high reliability, long service life, high precision, convenient installation and maintenance and less consumed energy, and the utility model is not afraid of the impact of a water hammer.
Description
The utility model relates to a kind of vertical bend pipe shunting high-pressure spray scale that is used for the metering liquid flow.
The instrument kind that is used for high-pressure fluid metering at present is less, and common have the vertical spiral type High-pressure watermeter of LXRG-50, " bend pipe a measuring method of introducing in the flow measurement handbook of the rugged great youth's work in a diligent mountain, the little palace of Japanese besides river Tian Yulang.The vertical spiral type High-pressure watermeter of LXRG-50, its metering mechanism is contained in the pipeline, the direct impact metre measuring mechanism of water under high pressure, not only resistance is big, power consumption is high, and serviceable life is short." the bend pipe measuring method of introducing in the flow measurement handbook is to utilize the pressure height of the bend pipe outside than bend pipe inboard, gets its differential pressure, mixes a cover secondary instrument and realizes metering.The secondary instrument cost of this bend pipe differential pressure measurement Law is higher, and maintenance bothers.
The purpose of this utility model provides a kind of simple and reasonable for structure, and cost is low, dependable performance, and accurate measurement, installation and maintenance are easy to use, the vertical bend pipe shunting high-pressure spray scale that the life-span is long.
The utility model realizes that the technical solution of above-mentioned purpose is, utilize the pressure differential of 90 ° of bend pipes of flow path at the beginning corner and the rear lower that turns round, get the mean flow rate in its pipe, partially liq in the trunk line is introduced in the rill scale be contained in the bypass, directly measured fluid flow in the trunk line by its ratio.I.e. flanged (FLGD) 90 ° of bend pipes in two ends, begin the corner at bend pipe and respectively open a hole with the rear lower that turns round, load onto an inlet in the hole of opening, beginning corner just in face of the connecting pipe (inlet of connecting pipe is less than liquid outlet) of liquid flow path direction, get the mean flow rate in its pipe, the liquid outlet of connecting pipe connects the inlet of rill scale, the liquid outlet of rill scale connects the inlet of one 180 ° U type liquid back pipe, the liquid outlet of U type liquid back pipe is connected with the inlet that returns the liquid straight tube, the turn round hole of rear lower of the liquid outlet that returns the liquid straight tube and 90 ° of bend pipes is connected, and makes the liquid that enters behind the connecting pipe flow path rill scale flow back to trunk line thus.All adopt adjustable union in the inlet of connecting pipe liquid outlet and rill scale inlet, rill scale liquid outlet and U type liquid back pipe, the liquid outlet and the inlet junction of returning the liquid straight tube of U type liquid back pipe.
The utility model compared with prior art owing to adopted abovementioned technology, has advantages such as simple in structure, that cost is low, power consumption is low, be not afraid of impact of water hammer, long service life, dependable performance, accurate measurement, installation and maintenance are easy to use.
Describe a specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the structural representation of vertical bend pipe shunting High-pressure watermeter.
Fig. 2 is the A-A cut-open view of Fig. 1.
Fig. 3 is the connecting pipe structural representation.
This flowmeter comprises that two ends have 90 ° of bend pipe table bodies 1 of flange, and table body 1 is made by No. 20 steel.Respectively open a hole in the beginning corner of its bend pipe table body 1 and the rear lower that turns round, two holes are in same level and maintain a certain distance, an inlet pack in the hole of opening, beginning corner just in face of the connecting pipe 2 of liquid flow path direction, connecting pipe 2 is made by stainless steel, the liquid outlet of connecting pipe 2 connects the inlet of rill scale 4, rill scale 4 is dry types, magnetic connecting piece in it is NdFeB rear-earth element or neodymium iron boron niobium and rare-earth element, the liquid outlet of rill scale 4 connects the inlet of one 180 ° U type liquid back pipe 5, liquid back pipe 5 is made by No. 20 steel, the liquid outlet of U type liquid back pipe 5 takes back the inlet of liquid straight tube 6, return liquid straight tube 6 and made by No. 20 steel, the liquid outlet that returns liquid straight tube 6 and 90 ° of bend pipe table bodies 1 hole that rear lower opens of turning round is connected.In the inlet junction of connecting pipe 2 liquid outlets and rill scale 4 inlet junctions, rill scale 4 liquid outlets and U type liquid back pipe 5, the liquid outlet and the inlet junction of returning liquid straight tube 6 of U type liquid back pipe 5 all adopt adjustable union 3 to realize being fastenedly connected, adjustable union 3 is made by stainless steel.
During use this flowmeter is installed on the water supply line, water flowing, the part water in the trunk line enters connecting pipe, the rill scale of flowing through, U type liquid back pipe, returns the liquid straight tube, flows back in the trunk line, realizes directly measuring total flow in the trunk line by ratio.
Claims (4)
