Abstract

The invention relates to the technical field of automobile hydrogenation, in particular to a hydrogenation gun which comprises a valve body, a gas return connector and a gas inlet connector are formed in the valve body, a shell is arranged on the outer wall of the valve body, a handle is arranged on the valve body, and the handle drives a cam, a valve rod and a bearing to rotate by 180 degrees around the valve body. When the valve rod rotates, the three-way ball is indirectly driven to rotate by 180 degrees at the same time. The hydrogenation gun is used for being connected with a hydrogen fuel automobile steel cylinder, hydrogen is injected into the steel cylinder, and the hydrogen enters the hydrogenation gun from the gas inlet connector, enters the valve body through the valve clack and the three-way ball and then is injected into the automobile steel cylinder through the valve element. After filling is completed, residual hydrogen in the gun is controlled by the three-way ball to enter the gas return connector to be discharged; and the three-way ball body is controlled by a valve rod driven by the handle to rotate by 180 degrees, so that the switching of the connection between the steel cylinder and the air inlet interface and the connection between the steel cylinder and the air return interface is realized.

Description

technical field [0001] The invention relates to the technical field of automobile hydrogenation, in particular to a hydrogenation gun. Background technique [0002] In recent years, more and more hydrogen fuel vehicles have been put on the market, and hydrogen refueling guns, as a necessary facility for refueling, have also ushered in a broad space for development. Well-known foreign companies have taken the lead in investing in technology research and development, and launched related hydrogen refueling gun products. [0003] At present, the hydrogen refueling guns used in the hydrogen refueling machines in the Chinese market are very expensive, about 100,000 yuan each, and the supply period is very long. Usually, it takes half a year to arrive after ordering, and there are no domestic hydrogen refueling guns. Maintenance capability, after the hydrogen refueling gun fails, it can only be sent back to Germany for maintenance, which greatly affects the development of domestic...
