1. The structure of the receiver and transmitter

The barrel adopts eccentric flat reducers, wheel paddle, clamp and lock ring type fast opening blind plate structure.

A launcher is used to adjust the pipe cleaner to achieve the best position in the barrel and serve to prevent pipe cleaner, quick opening blind plate opens clear residual pressure in the pipe tube effect under the return tube is avoided. Do not go out in the barrel after the booster.

2, materials

The cylinder body and the guide tube: Q345R, 16Mn, No. 20.

Fast opening blind plate: 16Mn III forging

Seal: PTFE polyethylene rubber, Ding Qing

3, quality system

Implement ISO9001 quality certification system
