Force transducer 22 accurately monitors the pressure in capsule, if not reaching sizing pressure requirements, reports to the police, while not allowing vulcanizer to close
Mould, prevents damaged tire；First pressure switch 23 monitors whether capsule pressure under die opening state has rising suddenly, if there is liter suddenly
Height, first pressure switch 23 will send reports to the police and sends control signal, and vulcanizer opens vacuum-pumping pipeline to reduce in capsule
Pressure, prevent capsule from explosion occurring and produces dangerous；The range ability of first pressure sensor 21 is larger, can prevent capsule
Interior pressure still can be with the intracapsular pressure of real-time detection plastic emitting when increasing to over the security measurement scope of second pressure sensor 22 suddenly
Power.
Matched moulds：After the completion of one-step building, by mould matched moulds, first pressure switch 23 is closed.
Secondary sizing：After matched moulds, sizing nitrogen pipeline 4, first pressure sensor 21 and second pressure sensor 22 are in
Opening, second pressure sensor 22 accurately monitors the pressure in capsule, if not reaching sizing pressure requirements, reports to the police, and
Subsequent processing is not allowed access into；The range ability of first pressure sensor 21 is larger, can prevent glue intraluminal pressure from raising suddenly
More than second pressure sensor 22 security measurement scope when still can be with the intracapsular pressure of real-time detection plastic emitting.
Sulfuration：After the completion of secondary sizing, sizing nitrogen pipeline 4 is closed, start stop valve 32 to open high steam air inlet
Pipeline 3, opens regulating valve 31, closes second pressure sensor 22, and high steam air inlet pipeline 3 is filled with the height of 1.9MPa to capsule
Pressure steam, can make the pressure in capsule be maintained at 1.9MPa by regulating valve 31 with the flow of accurate adjustment high steam, meet
The temperature and pressure technological requirement of sulfuration；Close high steam air inlet pipeline 3 and open high pressure nitrogen pipeline 5, fill into capsule
Enter the high pressure nitrogen of 2.8MPa, make tire blank outer surface realize squeezed tight with mould inner surface, it is ensured that vulcanised tyre finished product has
There is excellent performance；First pressure sensor 21 is constantly in opening, and whether the pressure in real-time monitoring capsule meets sulfur
Change technological requirement.
Nitrogen recycling, evacuation：After sulfuration terminates, high pressure nitrogen pipeline 5 is closed, open second pressure switch 24, opened
Nitrogen recycling pipeline 7, the nitrogen recycling in capsule is clean, vacuum-pumping pipeline 6 is then turned on, make reduced pressure in capsule extremely
Meet die sinking to require, and guarantee that glue intraluminal pressure reaches safety value and die sinking safety by second pressure switch 24.
Die sinking：Glue intraluminal pressure reaches and is molded after die sinking safety value, takes out finished tire, carries out next round sizing and sulfuration
Technique.
It should be noted that except the sliding window formula regulating valve in the present embodiment, regulating valve 31 is it is also an option that other knots
Structure and form, as long as the high steam flow in accurate high adjustment high steam air inlet pipeline 3, other structures can be realized
The regulating valve 31 of form is fallen within protection domain of the present utility model.
