Muscle.
The beneficial effects of the utility model are: relative to prior art, and this utility model arranges at the two ends of corrugated tube and holds
Thrust ring flat-plate, arranges load bolt between ring flat-plate, thus effectively reduces the length of load bolt.When opening of device runs
Time, the moment impact ripple that medium injection pipeline produces is delivered to the pipeline of the other end by the entrance point of joint by power transmission bolt
On, make impulsive force be stretched by pipeline and gradually weaken.This utility model can reduce medium stream with the setting of bore mozzle
Dynamic resistance, when medium flows through telescopic joint, will not produce traditional jointing mozzle internal diameter and reduce the larynx hoop of formation, effectively reduce
Media flow and the resistance that produces.This utility model is long for service life, it is achieved non-maintaining, and the scope of application is bigger.
