Abstract

The invention discloses a loose joint device with a grounding ring. The loose joint device comprises a nut, a sealing washer, the grounding ring and a bellmouth. The nut is provided with a through hole which is through left and right, the left side part of the through hole is provided with an internal thread and a threaded connector used for being connected with the electromagnetic flow sensor, and the right side of the through hole is provided with an inward flange used for locking the bell mouth; the socket is provided with a through hole penetrating left and right, and the left side of the socket is provided with an outward turnup which is matched with the turnup on the right side of the nut and used for locking the socket; an annular sealing gasket is arranged on the end face of the left flanging of the socket and is used for providing sealing during connection of a threaded interface of the electromagnetic flow sensor; an annular grounding ring is arranged between the inward flange of the nut and the outward flange of the bell mouth; the nut and the sealing washer are made of insulating materials, and the grounding ring and the bellmouth are made of conductive materials. The device is simple in structure, convenient to install, easy to maintain and capable of effectively solving the diversity of on-site installation forms.

Description

technical field [0001] The articulation device with a grounding ring described in the present invention relates to the technical fields of installation and grounding of electromagnetic flow sensors, in particular to the installation and grounding of electromagnetic flow sensors in the fields of central heating systems and water system air conditioners. The invention is suitable for the installation and grounding of products such as balance heat meters, electromagnetic flow sensors, electromagnetic water meters, electromagnetic heat meters, electromagnetic flowmeters with screw connections, and the like. Background technique [0002] The electromagnetic flow sensor is a flow measuring instrument based on Faraday's electromagnetic induction principle. It is proportional to the flow rate of the fluid, so as to obtain the flow rate of the fluid, and then obtain the flow rate of the fluid. In order to generate a magnetic field, an excitation coil is installed around the measurin...
