Problems solved by technology
[0002] At present, most of the high-pressure bypass valves in power stations cause the valve seat to be washed due to long-term operation or actuators. High-quality steam is directly discharged into the condenser, which affects the efficiency of the unit
The valve seat of the high-pressure bypass valve is usually connected to the steam pipeline by welding. If the valve seat of the high-pressure bypass valve is sent to the manufacturer for overhaul during the maintenance period, the high-temperature and high-pressure steam pipeline needs to be cut. After the repair, welding, heat treatment and flaw detection are required, and the workload is very large. and expensive
Grinding and repairing the valve seat at the maintenance site saves time, labor and cost, but the on-site grinding of the valve seat of the high-pressure bypass valve requires a set of special tools

Compared with the prior art, the purpose of repairing of a valve body of the high-voltage bypass valve is achieved, and the grinding device has the advantages that the maintenance cost is saved, the working efficiency is improved, the processing and manufacturing cost is low, and operation is convenient and fast.
Description
technical field [0001] The invention relates to a maintenance tool for a valve of a power station, in particular to a grinding device for a valve seat of a high-pressure bypass valve of a power station. Background technique [0002] At present, most of the high-pressure bypass valves in power stations cause erosion of the valve seat due to long-term operation or actuators. High-quality steam is directly discharged into the condenser, which affects the efficiency of the unit. The valve seat of the high-pressure bypass valve is usually connected to the steam pipeline by welding. If the valve seat of the high-pressure bypass valve is sent to the manufacturer for overhaul during the maintenance period, the high-temperature and high-pressure steam pipeline needs to be cut. After the repair, welding, heat treatment and flaw detection are required, and the workload is very large. And the cost is high. Grinding and repairing the valve seat at the maintenance site saves time, labor...
