Diesel engines have the characteristics of large torque, high thermal efficiency and good economic performance, and are usually used in mobile equipment or transportation tools (such as vans, trucks, forklifts, cranes, well repair equipment, drilling rigs, excavators, portable generators and welding trucks), emergency vehicles (such as fire trucks and ambulances) and small processing equipment (such as lawn mowers, blowers, generators, compressors, welders and pumps).

[0003] Common valves on the market usually include a valve plate that can adjust the pipeline cut-off and opening of the diesel engine and a locking mechanism that can lock the position of the valve plate. In order to ensure the sealing, the factory usually installs a sealing ring at the valve mouth to ensure that there is no leakage between the valve plate and the support seat. However, the existing sealing ring is usually directly fixed to the support seat by injection molding, which is difficult to replace later. For example, the utility model with announcement number CN202215364U discloses an electronic throttle with an injection-molded sealing ring. [Contents of the utility model]
