The feed liquor port of pedestal is tightly connected by removable mode.The outlet end mouth of gun body and the feed liquor port of pedestal link together
And when the outlet end mouth of driving mechanism driving liquid feeding spool opening gun body, liquid feeding spool pushes the feed liquor that pedestal is opened by liquid spool
Port.
Further, driving mechanism includes screw-casing and guide rod, and the outer wall of screw-casing is fixed or is integrally disposed upon in gun body
On the inner wall of chamber；Screw-casing madial wall is equipped with helicla flute；Guide rod is connected with liquid feeding spool, and the both ends of guide rod are located at spiral
In slot；When screw-casing positive and negative rotation, guide rod is moved back and forth along helicla flute, and drives the opening and sealing gun body of liquid feeding spool
Outlet end mouth.The inner wall of gun body is equipped with directive wheel；One end outer wall of pedestal feed liquor port is equipped with annular groove and docking is open,
Docking opening is extended to from the end face of pedestal in annular groove；Liquid feeding rifle and when being docked by liquid seat, directive wheel by docking be open into
Enter in annular groove.
Since liquid feeding rifle uses spiral nested structure, liquid feeding rifle is docked with by liquid seat, and when not rotating, Butt sealing circle makes
Liquid feeding rifle is sealed with being formed by liquid seat interface, liquid feeding spool and has been contacted but still each self sealss by liquid spool, is avoided
Gun body and pedestal just connect the leakage phenomenon for turning on and generating.The gun body of liquid feeding rifle is rotated in the forward direction, helicla flute, which pushes, to be oriented to
Bar moves, and guide rod drives liquid feeding valve core movement, charging valve core ribbon dynamic by liquid valve core movement, liquid feeding rifle and by liquid seat inner passage
Conducting.When exiting liquid feeding rifle, gun body is reversely rotated, helicla flute pushes guide rod to drive liquid feeding valve core movement, closed by liquid spool
Close under the action of spring and move, liquid feeding spool with detached by liquid spool before, liquid feeding spool is sealed with docking valve seat and formed, by liquid valve
Core is formed with pedestal and is sealed, thus, when liquid feeding rifle by liquid seat with being detached, without any residual liquid, and then realize LNG filling
Zero leakage.
Directive wheel enters annular groove by docking opening, and gun body is connect with by liquid seat by directive wheel and annular groove, gun body
Can be rotated relative to pedestal, make liquid feeding rifle and connected by liquid seat, disconnect it is extremely convenient and quick, it is easy to operate.
