Description

TECHNICAL FIELD

[0001] The utility model relates to valve port polishing device technology field that electromagnetic flowmeter converter processing uses, specifically is a kind of valve port polishing device that electromagnetic flowmeter converter processing uses. BACKGROUND

[0002] In the manufacture of key components of industrial measuring equipment, the surface quality of fluid control components directly affects the performance of the equipment. For example, the geometric accuracy and surface finish of the core channel of a measuring unit that works on the principle of electromagnetic induction directly determine the stability of medium flow. When the fluid flows through the machined surface, micro-level gullies can cause the destruction of laminar flow to form vortex flow, which not only causes electrode signal fluctuation, but also may cause cavitation effect to accelerate component wear. By eliminating surface burrs and mechanical stress concentration points through precision machining process, higher smoothness allows the fluid to form a stable boundary layer. In actual operation, the optimized flow channel structure can effectively reduce the kinetic energy loss when the medium passes through, and the differential pressure loss can be controlled within 70% of the traditional structure, which is particularly important for measuring complex media such as high-viscosity petroleum or fiber-containing wastewater. Dynamic compensation technology is used in the machining process to correct tool path deviation in real time, and non-contact measurement means is used to monitor machining quality, to ensure that the shape tolerance of the key parts does not exceed 8μm, which is equivalent to 1 / 10 of the thickness of A4 paper. This manufacturing standard allows the equipment to maintain the integrity of the sealing structure when in contact with acidic or alkaline media or under high temperature and high pressure conditions for a long time, while keeping the zero drift within 0.3% of the full scale, significantly improving the long-term stability and working condition adaptability of the measuring system.
