Abstract

The invention discloses an inserted electromagnetic flowmeter and a mounting method. In the water supply of a pipe network, more and more flowmeters are used in large water user metering and region metering systems, and the leak rate is reduced. The inserted electromagnetic flowmeter can provide two-way high-accuracy measurement, and is an ideal flowmeter for leakage detection. The existing inserted electromagnetic flowmeter mostly consists of movable components, is short in service life, weak in antijamming capability, unreliable in measurement, high in manufacturing cost and complex in mounting. The inserted electromagnetic flowmeter comprises a mounting base (2), wherein the mounting base is connected with one end of a ball valve (4); the other end of the ball valve is connected with a flange (3); the connecting flange is connected with an end socket (5); the mounting base, the ball valve, the flange and the end socket are respectively connected with an electromagnetic flow sensor (6) which is connected with a junction box (7). The inserted electromagnetic flowmeter and the mounting method are used for measuring liquid flow.

Description

Inserted electromagnet flow meter and installation method
technical field:
the present invention relates to a kind of inserted electromagnet flow meter and installation method.
background technology:
in pipe network water supply, increasing flowmeter is for large water user's metering, area meterin system, to reduce leak rate.The loss due to leakage monitoring of realization in pipe network, need to monitor water consumption lower night.
inserted electromagnet flow meter can provide two-way high-acruracy survey, is the desirable flowmeter of soil's rigidity.Meanwhile, outstanding repeatability, guarantees to only have real flow sudden change just detected.But the inserted electromagnet flow meter using is at present comprised of movable part mostly, serviceable life is short, and a little less than antijamming capability, it is unreliable to measure, and cost of manufacture is high, installs complicated.
summary of the invention:
the object of this invention is to provide a kind of inserted electromagnet flow meter and installation method.
above-mentioned object realizes by following technical scheme:
a kind of inserted electromagnet flow meter, its composition comprises: mounting seat, described mounting seat is connected with ball valve one end, the described ball valve other end is connected with flange, described joint flange is connected with end socket, described mounting seat, described ball valve, described flange, described end socket connect respectively at electromagnetic flow transducer, and described electromagnetic flow transducer is connected with terminal box.
described inserted electromagnet flow meter, described mounting seat is arranged on tested pipeline.
described inserted electromagnet flow meter, it is inner that described electromagnetic flow transducer inserts described tested pipeline.
described inserted electromagnet flow meter, described ball valve is DN50 ball valve, described rubber seal, gland nut, collet threaded seat connect.
an installation method for inserted electromagnet flow meter, the method comprises the steps:
(1) welding slag and the burr of mounting seat on cleaning tested pipeline;
(2) turn off upstream flowrate by-pass valve control or adopt low pressure to supply water;
(3) ball valve is installed in described mounting seat, notes the vast sky chamber of described ball valve upwards;
check described ball valve whether can standard-sized sheet, complete shut-down, collet threaded seat, gland nut and rubber seal are installed on ball valve, unclamp setscrew nut, electromagnetic flow transducer insertion rod is inserted to described tested pipeline by described ball valve, should notice that described electromagnetic flow transducer Directional Sign bar sensing should be consistent with direction of flow simultaneously.
beneficial effect:
1. simple in structure, firm, the no-movable part of the present invention, long service life, measurement is reliable, antijamming capability is strong, volume is little, lightweight, easy for installation, maintenance is little, measurement range is large, measure the impact that not changed by temperature, density, pressure, viscosity, conductance etc., the pressure loss is zero.
the present invention can install, dismantle in the situation that continuing to flow, and for user's maintenance has brought convenience, manufacturing cost and the erected cost of more general electromagnetic flowmeter are low, is particularly suitable for medium-large caliber pipeline flow and measures.
the present invention adopts advanced processing technology, and the features such as solid-state encapsulation, vibration resistance, life-span length, make instrument have good measuring accuracy and stability, and flowmeter not only has the output of 4-20mA current signal, also has the output of 1-2000HZ frequency simultaneously.
fluid-velocity survey scope of the present invention: (0.05-10) m/s; Measuring channel diameter: DN(32-3000) mm; Measuring accuracy: 0.5-1.0 level; Working pressure: < 1.6MPa; Medium temperature: 0-80 ℃; Power consumption: < 20VA; Connected mode: flange connects, is threaded.
