Described airway, by special rustless steel dipping plug, uses specific impregnation technology technology to make; Under 18～28 DEG C of room temperatures, the environmental condition of relative humidity 40%～70%, this impregnation technology completes by equipment frocks such as liquid stream circulating device, electric heating constant temperature baking oven and working plates, described liquid stream circulating device comprises a discharge tank, a magazine and a rewinding bucket, discharge tank and rewinding bucket also and between magazine are connected by tube for transfusion in the both sides of magazine, fill and mix silica gel material in discharge tank and magazine; Described rustless steel dipping plug is cylinder, comprises barred body and rod seat, and both are integrated, and the cross-sectional area of rod seat is greater than barred body; On described working plate, have the eyelet matching each other with barred body size, impregnation technology flow process is:
(1) clean rustless steel dipping plug with cleaning cloth, at surface-coated silicone oil one deck of barred body, and barred body is inserted in the eyelet on working plate until rod seat contacts with working plate to vertical hanging;
(2) working plate that rustless steel dipping plug is housed is put into electric heating constant temperature baking oven and carry out drying heating for the first time, after taking-up with insert by it in magazine, flood for the first time curing, 5 seconds of hardening time, take out rustless steel dipping plug, now barred body periphery has formed ground floor tubular shape colloid, then rustless steel is flooded to plug and puts into electric heating constant temperature baking oven and carry out for the first time drying sulfuration;
(3) after drying sulfuration for the first time finishes, take out the rustless steel dipping plug with ground floor tubular shape colloid, after cooling 5 minutes, rustless steel is strengthened to seal wire to be placed on rustless steel dipping plug, then rustless steel being flooded to plug puts into electric heating constant temperature baking oven and carries out for the second time drying heating, after taking-up with insert by it in magazine, flood for the second time curing, 5 seconds of hardening time, take out rustless steel dipping plug, now rustless steel dipping plug periphery has formed second layer tubular shape colloid, this layer of tubular shape colloid wraps rustless steel and strengthens seal wire, then rustless steel being flooded to plug puts into electric heating constant temperature baking oven and carries out drying sulfur for the second time,
(4) after drying sulfuration for the second time finishes, take out rustless steel dipping plug with insert by it in magazine, flood for the third time curing, 5 seconds of hardening time, take out rustless steel dipping plug, now rustless steel dipping plug periphery has formed the 3rd layer of tubular shape colloid, then rustless steel is flooded to plug and puts into electric heating constant temperature baking oven and carry out drying sulfuration for the third time;
(5) after drying has vulcanized for the third time, take out rustless steel dipping plug by its natural cooling, then rustless steel being flooded to plug separates with the tubular shape colloid of strengthening seal wire with rustless steel, and tubular shape colloid is put in to arc radius on the setting tooling of (140 ± 20) mm, put into set temperature and be the baking oven of 170 DEG C and make sizing and solidifying, after 90～120 minutes, take out, now make with the airway of rustless steel reinforcement seal wire;
In above-mentioned impregnation technology step, in the time that the mixing silica gel material in magazine is not enough, the mixing silica gel material in discharge tank is injected to magazine, ensure that the mixing silica gel material in magazine fills, unnecessary mixing silica gel material flows in rewinding bucket; When mixing silica gel material in rewinding bucket is too much, the mixing silica gel material in rewinding bucket is injected to discharge tank, so circulation.
