Seal ring communicates.
The rotary shaft sealing gland ring type sealing device, the sealing gland ring outside have a circle outer groove, the gas
There is a circle inner groove on the inside of seal ring, one group of gas being evenly arranged is provided between the inner groove and the outer groove
Hole.
The rotary shaft sealing gland ring type sealing device, is additionally provided between the ring flange and the rotary shaft and connects
Contact-type sealing ring.
The rotary shaft sealing gland ring type sealing device, the depth and width phase of the outer groove and the inner groove
It is less than the width of the outer groove Deng the diameter of, the stomata.
The length of the rotary shaft sealing gland ring type sealing device, the stomata is 2-9mm.
A kind of encapsulating method of rotary shaft sealing gland ring type sealing device, this method comprises the following steps：Positive pressure gas passes through tune
Fast valve enters in tracheae, and positive pressure gas is entered by tracheae, angle coupling in the air flue of ring flange, eventually enters into the outer shroud of sealing gland ring
In slot, positive pressure gas is entered by stomata in inner groove, and positive pressure gas carries out uniform pressure distribution in inner groove, and it is close to form high pressure chest progress
Envelope.
Advantageous effect：
1. the present invention is sealed using sealing gland ring, positive pressure air cavity is formed between sealing gland ring and rotary shaft, sealing gland ring is adopted with rotary shaft
With contactless, when material inside feed bin is toward external leakage, positive pressure air prevention encountered, can not continue to move to, reach anti-stopping leak
Reveal purpose.
The present invention is combined using the sealing of sealing gland ring with contact seal, and the temperature that contact seal friction generates is reduced, and is prevented
Only axle fracture phenomenon, innovation prevent dust from spraying air inflow step-less adjustment using duct type speed governing valve.
The present invention is arranged sealing gland ring and seals, and is provided with outer groove, inner groove and stomata on sealing gland ring, can separately enter outer shroud
Gas in slot, inner groove and stomata is evenly distributed with, and ensures sealing effect.
