Problems solved by technology
Although the arrangement of the valve stem assembly of the current better high-temperature butterfly valve for marine diesel engines has a storage space for particulate matter, the particulate matter may still accumulate on the end of the valve stem away from the valve plate, resulting in increased valve torque and seizure
In order to control the valve torque within a certain range, the valve needs to be dismantled and cleaned after a period of use. Currently, the dismantling and inspection cycle of this type of valve stem assembly arrangement is also relatively short.

The invention discloses a high-reliability high-temperature buttery valve and application of the butterfly valve on a marine diesel engine. The high-temperature butterfly valve comprises a valve body, a valve plate is arranged in the valve body, one end of the valve plate is connected with an upper valve rod, and the other end of the valve plate is connected with a lower valve rod. Storage space is formed between the upper valve rod and / or the lower valve rod and the valve body and used for storing particles. The valve body is provided with through holes communicated with the storage space. The invention further provides the application of the butterfly valve on the marine diesel engine. The high-reliability high-temperature buttery valve is provided with two sealing rings, so that the sealing performance is good, reliability is high, the particles in the storage space can be periodically removed through the through holes, the dismounting and checking period of the valve is shortened, and the requirement for the performance of the high-temperature butterfly valve of the marine diesel engine in the actual application process can be met.
Description
technical field [0001] The invention relates to the field of valves, in particular to a high-temperature butterfly valve with high reliability and its application on marine diesel engines. Background technique [0002] High-temperature butterfly valves for marine diesel engines are mainly used to adjust the exhaust gas flow of diesel engines. Compared with other application objects of high-temperature butterfly valves, marine diesel engines have the characteristics of high leakage level requirements, high vibration levels of exhaust systems, and large content of exhaust particles. Therefore, marine diesel engines have higher requirements on the sealing performance, vibration resistance and reliability of high temperature butterfly valves. [0003] At present, high-temperature butterfly valves specially used in marine diesel engines have not been developed in China. The high-temperature butterfly valves imported from abroad on the market mainly have sealing measures or semi-c...
