Detail
1. Characteristic:
QY494 one-way gas guide tap is an auxiliary component used for pipeline connecting school, it is a joint device connecting fixed gas pipeline and rotating gas pipeline, it consists of shell, central tube (punching tube), bearing, seal ring, spring basket and air inlet end cover. The center tube is connected to the rotating shaft, and the seal ring is sealed with the end face of the center tube under the action of the spring to form a channel. Compressed air is output from the input port through this channel.
QY494 one-way air guide tap is one of the most used auxiliary components in the pneumatic system of oil drilling rigs, geological exploration rigs and complete well machines, mainly used in the input line of air tire clutch, but also in other pneumatic systems.
