Abstract

The utility model relates to the field of diesel engine fuel injection valves, and in particular to a multifunctional dual-fuel low-speed diesel engine fuel injection valve. The multifunctional dual-fuel low-speed diesel engine fuel injection valve includes a check valve, a top cover, a valve seat, a nozzle, a limiting structure and an anti-skid structure. The check valve is located at the top and is used for high-pressure fuel inlet. The top cover is located below the check valve to enhance the stability of the lift. The valve seat is located below the top cover and is used to control the high-pressure hydraulic oil inlet of the thrust block stroke. The nozzle is located at the lower part of the valve seat and is used to control the injection of high-pressure fuel. A limiting structure is provided between the nozzle and the valve seat, and the nozzle is quickly disassembled and assembled through the limiting structure. An anti-skid mechanism is provided on the top cover, and the anti-skid structure is used to limit the loosening of the top cover when in use. The utility model can quickly disassemble and assemble the nozzle through the designed limiting structure, which greatly improves the convenience of repairing and replacing the nozzle, reduces downtime, and improves work efficiency.
