Problems solved by technology
Usually the ship engine has high power and large displacement. If the natural gas injection valve of the vehicle engine is used, it cannot meet the flow requirements of the marine gas / dual-fuel engine. Therefore, some large-flow natural gas is designed and put into the ship market. Optimizing gas / dual fuel engine performance requires optimization of natural gas injection and intake air mixing
[0003] There are related natural gas injection valves disclosed in the prior art. When the injection valve is working, the rubber pad is mainly driven by the coil to seal and cut off the flow. However, because the coil generates a certain thrust and needs to cut off the flow quickly, the rubber pad If the moving speed is fast, the large kinetic energy of the rubber pad will directly act on the rubber pad at the moment of sealing (that is, contact impact), resulting in a short service life. Therefore, it is necessary to provide a new high-flow, dual-fuel The engine gas fuel diversion injection machine solves the above-mentioned technical problems

The invention provides a gas fuel drainage injection machine of a high-flow dual-fuel engine . The gas fuel drainage injection machine of the high-flow dual-fuel engine comprises a shell, an air outlet pipe, an air inlet pipe, a lantern ring, a first sealing gasket, a third sealing ring, through holes, a sealing energy release mechanism and a driving mechanism; the air outlet pipe and the air inlet pipe are connected in the shell, the air inlet pipe and the air outlet pipe are coaxially arranged, one end of the air inlet pipe is connected with the lantern ring, the first sealing gasket and thethird sealing ring are fixedly connected to the lantern ring, and the through holes are formed in the lantern ring and the air inlet pipe; the sealing energy release mechanism movably connected withthe first sealing gasket is connected to the end, close to the air inlet pipe, of the air outlet pipe; the driving mechanism for driving the air inlet pipe to move is arranged between the shell and the air inlet pipe, and the driving mechanism is slidably connected with the air inlet pipe. According to the gas fuel drainage injection machine of the high-flow dual-fuel engine, energy can be released through the sealing energy release mechanism when a valve is closed, so that the impact energy is effectively reduced, and the service life of the mechanism is prolonged.
Description
technical field [0001] The invention relates to the field of injection machines, in particular to a large-flow, dual-fuel engine gas fuel diversion injection machine. Background technique [0002] In recent years, the continuous and rapid development of my country's economy has created the prosperity of the shipbuilding industry. Both the number of ships and the total deadweight tonnage have shown explosive growth. At present, most ships are powered by diesel engines, and the overall technical level of ship engines is not high. Therefore, the impact and damage caused by ship emissions on the environment are becoming more and more serious. Natural gas is an alternative energy source with rich resources and clean combustion. The development of natural gas engine technology is considered to be an effective technical measure to alleviate the current energy and environmental pressure. Therefore, gas fuel-powered ships (diesel / natural gas or single gas fuel) have received The att...
