[ China Instrument Network Instrument R & D ] Recently, Shanghai Ziyi's subsidiary, Shanghai Ziyi Xixi Valve Co., Ltd. (referred to as "self-instrument CCI") completed the K2 project delivery task, which is the company completed the turbine side valve The first batch of products after localization. The smooth implementation of the project marks the realization of the localization of the exhaust valve next to the turbine, filling the gap in the design and manufacture of the side valve of the domestic steam turbine.
In the thermal system of thermal power units, the steam turbine bypass system has become an important part of the thermal system of the intermediate reheat unit. When the operating conditions of the boiler and the steam turbine do not match, the steam produced by the boiler and the steam required by the turbine The difference between the quantities may be introduced into the condenser without entering the steam turbine and being depressurized by the bypass pressure reduction. The main functions of the turbine bypass system are steam regulation – high pressure throttling and superheated steam cooling. The bypass valve must perform these functions and achieve the target pressure and temperature without excessive noise and vibration and wear of the valve trim.
In order to solve the localization requirements of nuclear power key equipment, CCI has applied a series of British CCI severe working conditions to apply valve technology to overcome a series of problems and design to eliminate various problems caused by high pressure difference, high energy and high flow rate fluid. Effectively reduce noise, achieve fast opening, fast closing, fast adjustment function, thus filling the blank of the project. The completion of the design and manufacture of the project has taken a solid step in the company's manufacturing of high-end regulating valve manufacturers. The company will continue to make unremitting efforts towards this goal.
