Abstract

The invention provides a brake handle protective cover and a manufacturing method thereof.The brake handle protective cover comprises a plurality of gasket bolts, the gasket bolts are arranged at the four corners of a protective base correspondingly, a front protective plate is arranged at one end of the top face of the protective base, a rear protective plate is arranged at the other end of the top face of the protective base, and a left protective plate is arranged on one side of the front protective plate and one side of the rear protective plate; a left protection plate is arranged on one side of the front protection plate, a right protection plate is arranged on the other side of the front protection plate and the rear protection plate, and protection turning covers are arranged above the front protection plate, the rear protection plate, the left protection plate and the right protection plate. By utilizing the transparency of the PVC plastic plate, the operation state of the brake device can be observed at any time, and faults can be found in time; in case of emergency, the protective turning cover is easily and quickly turned up through the handle, and the brake handle is quickly pulled to realize on-site brake of the steam turbine; the requirements of newly-built unit specifications are met, and the probability that the unit passes through one-time monitoring is improved.

Description

technical field [0001] The invention relates to the technical field of installation of industrial steam turbine speed control systems, in particular to a brake handle protective cover and a manufacturing method thereof. Background technique [0002] In the process of industrial steam turbine operation, a set of hydraulic speed control system is often used, through which the switch of each main valve and regulating valve of the steam turbine is controlled, and then the load of the steam turbine is controlled. This system is usually equipped with a set of mechanical flyweight protection device, two sets of electric overspeed protection device and a set of on-site manual brake device. [0003] However, at present, the manual brake devices configured by domestic steam turbine manufacturers are usually exposed types, which do not meet the requirements of "Technical Specifications for Electric Power Construction and Construction Part 3: Steam Turbine Generator Sets". In addition,...
