A leak-proof electric contact water level gauge

Abstract

The invention relates to the field of gauge detection and automatic control, in particular to a leakproof water level gauge with an electric contact. The water level gauge with the electric contact comprises a water level gauge body, an installation cylinder and a pressing end cover, wherein the water level gauge body is installed in the installation cylinder, the pressing end cover is firmly arranged on the end portion of the water level gauge body in a pressing mode, the water level gauge with the electric contact further comprises a detection structure used for detection, a first installation hole used for installation of the water level gauge body is formed in the installation cylinder, and the first installation hole is provided with a first inclined side surface structure; the waterlevel gauge body comprises a detection part and an installation part connected with each other, and the installation part is provided with a second inclined side surface structure attached to the first inclined side surface structure; the installation part is provided with an installation platform, the pressing end cover is provided with a groove structure, and the installation platform is matchedwith the groove structure. By means of the water level gauge with the electric contact, reliable sealing of the water level gauge body, the installation cylinder and the sealing end cover is achieved, and it is prevented that damage to electrodes in processes of installation area vibration and medium flushing affects continuous production; moreover, additional auxiliary components and parts are not needed for sealing, so that the cost is lowered, the installation speed is improved, and the installation efficiency is increased.

Description

technical field [0001] The invention relates to the field of instrument detection and automatic control, in particular to a leakage-proof electric contact water level gauge. Background technique [0002] Electric contact water level gauge is a conventional detection equipment for soda tank type liquid level transmission, and it is widely used in automatic control systems. The working principle of the electric contact water level gauge is to measure the water level according to the different conductivity of steam and water. The electrodes are mounted on the water level container to form an electrode water level transmitter. The electrode core is insulated from the shell of the water level measuring container. Due to the high conductivity of water and small resistance, when the contact is submerged in water, the electrode core and the container shell are short-circuited, and the corresponding water level display light is on, and the electrode in steam has low conductivity an...

Problems solved by technology

[0003] In production and application, because the installation of the electrode and the electric contact water level gauge only depends on the thread and the copper gasket, during the installation vibration and medium washing sampling process, it is very easy to cause loosening, resulting in medium overflow and production stop
