Heat exchanger valve system for regulating e.g. exhaust gas flow, has housing with bypass outlet, through which large fluid flows are passed to heat exchanger based on position of valve gate, which is movable back and forth in housing

摘要

The system has a valve housing (2), which comprises an inlet (4) for the fluid flow and a heat exchanger outlet (11). One or more large fluid flows are fed to a heat exchanger e.g. cooler, through the heat exchanger outlet based on the position of valve body. The valve housing comprises an outlet e.g. bypass outlet (12). One or more large fluid flows are passed to the heat exchanger through the bypass outlet based on the position of a valve gate (16), which is movable back and forth in the valve housing. Independent claims are also included for the following: (1) a method for cleaning a heat exchanger valve system (2) a heat exchanger e.g. exhaust gas heat exchanger, with a heat exchanger valve system (3) an exhaust gas feedback system with an internal combustion engine, between whose exhaust gas receiving and feedback positions a heat exchanger valve system is connected.
