Abstract
The utility model relates to an unlined duct for electromagnetic flow sensors. The unlined duct comprises a duct body and flanges. The flanges are fixedly connected to two ends of the duct body. At least one pair of coil bases is disposed on the duct body. The middle of each coil base is provided with an electrode hole penetrating through the duct wall. Both the duct body and the flanges are made of engineering plastic. The coil bases are symmetrical with respect to circle center of the duct body. The lining-free duct is formed by one-step compression molding. A necessary metal processing step in conventional steel processing is omitted from the compression molding process compared with the processing technique of metal electromagnetic flow meters, and accordingly production efficiency is improved. The unlined duct is made of engineering plastic which has properties of corrosion resistance, insulation and the like. An anticorrosion insulating lining is omitted from the inner side of the duct wall, so that the number of parts and mechanism complexity are decreased. Production efficiency is improved, production cost is lowered, and economic benefit is increased greatly.
Description
Technical field
The utility model relates to the electromagnetic flow transducer field, is specifically related to a kind of linerless inner pipeline for electromagnetic flow transducer.
Background technology
Electromagnetic flowmeter is based on Faraday's electromagnetic induction law, magnetic field is set around conducting liquid, when conducting liquid in magnetic field during cutting magnetic line, produce the induced potential that is directly proportional with the liquid mean flow rate, its induced voltage signal detects by the electrode that two or more and liquid directly contact, and deliver to converter by cable and process, realize transient liquid flow, the demonstration of accumulation flow and communication and the control between data on flows and the microsystem.
Patent ZL200620127354.3 has announced a kind of pipe type electromagnetic flow sensor, but this patent is deposited invention employing stainless steel as material, need to anticorrosion and insulation in the inner-walls of duct pad.
Summary of the invention
The utility model proposes a kind of linerless inner pipeline for electromagnetic flow transducer for the problem that prior art exists.
The technical solution of the utility model is: a kind of linerless inner pipeline for electromagnetic flow transducer, comprise body and flange, flange is fixedly connected on the two ends of body, is provided with coil base on the body, and the middle part of coil base is provided with the electrode hole that runs through tube body wall.
Described linerless inner pipeline for electromagnetic flow transducer, the material of described body and flange is engineering plastics.
Described linerless inner pipeline for electromagnetic flow transducer, described coil base is at least a pair of, and symmetrical about the body center of circle.
The beneficial effects of the utility model are: 1. the utility model adopts a compression molding, and comparing with the electromagnetic current measuring device of existing metal material to have saved in the processing of conventional products iron and steel to have to get the metalworking operation, has greatly improved production efficiency.
2. material of the present utility model adopts engineering plastics to make, engineering plastics itself just have the characteristics such as anticorrosion and insulation, so lining anticorrosion and insulation has been saved in the tube body wall inboard, reduced the complexity of number of components and mechanism, this has not only improved production efficiency, simultaneously also reduce production cost, greatly improved economic benefit.
