Detailed description of the invention
As it is shown in figure 1, screw thread rifle pawl clamped-in style filling gun of the present utility model, mainly include upper cylinder body 4 and lower cylinder body 6,
Upper cylinder body 4 and lower cylinder body 6 are linked together by attachment block 5.Vacuum valve, fill valve and suck back valve be set in upper cylinder body 4, three
The spool 3 of control valve is arranged in three endoporus of upper cylinder body 4 (vacuum valve endoporus, fill valve endoporus and suck back valve endoporus), point
Do not control vacuum line, charging line and resorption pipeline.Upper cylinder body 4 is provided with respectively with vacuum valve, fill valve and suck back valve
Vacuum interface, filling interface and the resorption interface connected, external vacuum pipe is connected to vacuum interface, and external oil pipe is connected to filling
Interface, outside suction pipe is connected to resorption interface.
Connecting with handles 1 on upper cylinder body 4, handle 1 degree in a vertical angle with upper cylinder body 4 and lower cylinder body 6 is installed.Pacify on handle 1
Equipped with electric button 2 and display lamp.
The structure of lower cylinder body 6 is as in figure 2 it is shown, include clamp system and sealing mechanism.Clamp system is mainly by cylinder cap 10, pressure
Contracting spring 11, rifle pawl clamping sleeve 13, center contiguous block 16, rifle pawl seat 18 and rifle pawl 7 form.Cylinder cap 10 is arranged on transfer block 5
Bottom, center contiguous block 16 is bolted on the bottom of cylinder cap 10.Center contiguous block 16 connects and has filler pipe 9.In
