Description

Split combined electromagnetic flowmeter Technical Field The utility model relates to the technical field of electromagnetic flow meters, in particular to a split combined electromagnetic flow meter. Background An electromagnetic flowmeter is an instrument for measuring the volume flow of conductive liquid, and the working principle of the electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. When a conductive fluid flows through the measuring tube of the flowmeter, the exciting coil outside the measuring tube applies a magnetic field perpendicular to the flowing direction of the fluid, and induced voltage is generated when charged ions in the fluid move in the magnetic field. The magnitude of the electromotive force is in direct proportion to the average flow velocity of the fluid, the voltage signal is detected through electrodes arranged on two sides of the wall of the measuring tube, and the flow rate of the fluid can be calculated by combining the cross sectional area of the measuring tube. The coil and the electrode are packaged in the shell of the traditional electromagnetic flowmeter, when the coil or the electrode part is damaged, disassembly and maintenance are very complicated, and when the electromagnetic flowmeter cannot work normally due to the damage of the coil or the electrode part, the whole electromagnetic flowmeter is usually directly replaced, and one or a plurality of coils and electrodes can work normally, so that more waste is caused. Disclosure of utility model Based on this, the present utility model aims to provide a split combined electromagnetic flowmeter, so as to solve the technical problems mentioned in the background art. The split combined electromagnetic flowmeter comprises a first shell, wherein the top of the first shell is connected with a second shell, four supporting seats are fixed above the inside of the second shell and below the inside of the first shell, the top of the four supporting seats and the bottoms of the other four supporting seats are connected with protective shells, coils are arranged inside the two protective shells, clamping frames penetrate through the outer surfaces and the back of the first shell and the second shell, electrodes are connected inside the two clamping frames through sealing jackets, and two clamping bolts penetrate through one sides of the two clamping frames. According to the technical scheme, when the coil is damaged, the first shell, the second shell and the clamping frame are separated, the protective shell can be directly taken down for replacement without limitation, the coil is encapsulated and solidified by epoxy resin to form a form that the protective shell wraps the coil, stability and water and dust resistance of the coil are improved, when the coil is installed, the protective shell is only needed to be placed on the supporting seat, then the first shell, the second shell and the clamping frame are installed back, the outer ring of the protective shell is supported and limited by the supporting seat, the inner ring of the protective shell is supported and limited by the insulating lining, the outer surface and the back of the protective shell are supported and limited by the clamping frame, the coil is prevented from being driven to loosen and move by the protective shell, when the electrode is damaged, the clamping frame is only needed to be pulled out from the first shell and the second shell, then the clamping bolts are taken down, the two sides of the clamping frame are not influenced by pressure, so that the sealing sheath and the electrode can be directly taken down for replacement, the sealing sheath and the electrode are plugged into the sealing sheath, then the sealing sheath is plugged into the clamping frame, then the clamping bolts penetrate through the two sides of the clamping frame and are screwed down, the two sides of the clamping frames are tightly, and pressure can be applied to the two sides of the clamping frames, so that the electrode and the gap between the electrode and the outer shell and the electrode can be prevented from being leaked through the sealing sheath and the gap between the outer shell and the sealing sheath and the electrode can be prevented.
