Portable type valve sealing surface grinding device

Abstract

The invention discloses a portable type valve sealing surface grinding device. A grinding disc is circular and is horizontally arranged; a load-bearing bearing is arranged between the grinding disc and a base; the grinding disc is mounted on the load-bearing bearing; a first drive motor for controlling the grinding disc to horizontally rotate around the circle center of the grinding disc is arranged below the grinding disc; a swing arm mechanism comprises a swing arm horizontally arranged on a base, a swing disc and a drive disc; one end of the swing arm is fixedly connected to the outer wallof the swing disc, and the other end of the swing arm is fixedly connected to an eccentric hole of the drive disc; while the swing arm, the swing disc and the drive disc are connected together, an extending line of the swing arm passes through the circle center of the swing disc and the circle center of the drive disc; and moreover, while the drive disc rotates, the swing arm drives the swing discat the other end to perform eccentric swing. The portable type valve sealing surface grinding device is good in grinding effect, is convenient to carry, and is high in degree of automation.

Description

technical field [0001] The invention relates to a valve sealing surface grinding mechanism, in particular to a portable valve sealing surface grinding device. Background technique [0002] Valve is a device widely used in pressure equipment in electric power and petrochemical industries, especially the safety valve is the fundamental guarantee for the safe operation of the system. According to the relevant provisions of TSG ZF001-2006 "Safety Valve Safety Technology Supervision Regulations", the safety valve user must adjust the set pressure of the safety valve at least once a year to ensure the safe production of the enterprise. [0003] In the previous safety valve calibration work, there were many cases where the sealing surface of the safety valve was damaged and could not be sealed. However, because the maintenance and grinding equipment in the past was too heavy, it was impossible to transport the maintenance and grinding equipment to the production site as a whole, re...

AI Technical Summary

Problems solved by technology

[0003] In the previous safety valve calibration work, there were many cases where the sealing surface of the safety valve was damaged and could not be sealed. However, because the maintenance and grinding equipment in the past was too heavy, it was impossible to transport the maintenance and grinding equipment to the production site as a whole, resulting in the company's long-term safety inspection every year. When the valve is repaired, it is necessary to transport the safety valve to the calibration station for grinding and repairing, which greatly increases the operation and maintenance cost and time of the enterprise, and is not conducive to the energy saving and emission reduction of the enterprise

[0004] In addition, according to the grinding requirements of the valve sealing surface, the sealing surface ground by irregular motion can better ensure the grinding effect, but the current grinding does not have better irregular motion control, and the grinding effect is not good
