Abstract

The invention provides a ball valve for a dual-fuel diesel engine. The ball valve comprises an outer shell, a ball valve body, a ball body, a valve rod, a switching valve rod and a support. The outer shell is fixed in a fuel pipeline of a dual-fuel oil extraction machine, the ball valve body is arranged in the outer shell, an inlet and an outlet are formed in the ball valve body, the ball body is located in the ball valve body and provided with a through-flow hole, and one end of the valve rod extends into the ball valve body and is connected with the ball body so as to drive the ball body to rotate in the ball valve body in a reciprocating mode. The through-flow hole is controlled to be connected and disconnected with the inlet and the outlet. The valve rod is sleeved with the support, the support penetrates through the outer shell to be fixed to the fuel pipeline, the switching valve rod is arranged in the support and connected with the valve rod, and the switching valve rod is used for driving the valve rod to drive the ball to rotate in the ball valve body in a reciprocating mode. The ball valve is suitable for a fuel oil pipeline of a dual-fuel diesel engine.

Description

technical field [0001] The invention relates to the technical field of dual-fuel engines, in particular to a ball valve for dual-fuel diesel engines. Background technique [0002] With the gradual shortage of oil resources, looking for alternative energy sources for engines has become a common concern of governments and related research institutions. The main component of natural gas (NG) is CH4, which is a clean fuel. Compared with oil resources, China has abundant natural gas resources. Starting from the energy supply structure, the Chinese government firstly encourages and supports the development of natural gas engines. The dual-fuel diesel engine is a diesel engine that sends a mixture of natural gas and air into the cylinder and injects a small amount of diesel to ignite. It uses natural gas as the main fuel; and can switch between natural gas and diesel. The dual-fuel diesel engine fueled by natural gas can overcome the shortcomings of high NOx and PM emissions of d...
