Description
Technical field:
The present invention relates to a kind of tire forming vulcanizer, be specifically related to a kind of Hard-tube Structure Of High-temperature Inner-pressure Medium In-out Pipe Of The Central Mechanism Of Tire Shaping Vulcanizer.Belong to the vulcanizing equipment technical field.
Background technology:
Tire forming vulcanizer central authority high temperature internal pressure medium turnover pipe is the conduit that is input into, exports high-temperature medium to the tire forming vulcanizer central authority.Before the present invention made, what be used at present that the high temperature internal pressure medium turnover pipe of tire forming vulcanizer central authority adopts was a kind of hard tube structure, and it mainly is made up of inner catheter, outer tube, sealing gasket, ring assembly, gland etc.Described outer tube is enclosed within the inner catheter back segment, the outer tube front portion links to each other with the rear end of conducting sleeve face of vulcanizer central authority, the inner catheter leading portion is placed through in the guide pin bushing of tire forming vulcanizer central authority, ring assembly is placed on the inner catheter leading portion tube wall, gland is pressed on the ring assembly front end, fixedlys connected with adjustment screw with the guide pin bushing front end face of vulcanizer central authority.Mainly there is following deficiency in it:
1, only adopt the ring assembly sealing between inner catheter and the vulcanizer central authority guide pin bushing, radial clearance can occur between ring assembly wearing and tearing back and the inner catheter, the adjustment screw manual adjustments that occurs can only pressuredly covering behind the gap compensates, and adjustable range is narrow.Can not compensate automatically again, can influence the sealing reliability between inner catheter and the ring assembly like this.
2, ring assembly is made by elastomeric material, and its relatively poor to neutrality on inner catheter departs from the inner catheter tube wall easily, can aggravate wearing and tearing and leakage between ring assembly and the inner catheter like this.
3, ring assembly is formed by stacking by pressure ring and a plurality of sealing ring, and the lubricity between itself and the inner catheter tube wall is relatively poor, so also can aggravate the wearing and tearing between ring assembly and the inner catheter, shortens the service life of sealing ring.
4, the outer tube tube wall only adopts the sealing gasket sealing between vulcanizer central authority guide pin bushing, and sealing is relatively poor, and heat medium is revealed easily.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, the good Hard-tube Structure Of High-temperature Inner-pressure Medium In-out Pipe Of The Central Mechanism Of Tire Shaping Vulcanizer of sealing reliability between a kind of guide pin bushing of and tire forming vulcanizer central authority is provided.
The object of the present invention is achieved like this: a kind of Hard-tube Structure Of High-temperature Inner-pressure Medium In-out Pipe Of The Central Mechanism Of Tire Shaping Vulcanizer, comprise inner catheter, outer tube, ring assembly and gland, described outer tube is enclosed within the inner catheter back segment, the outer tube front portion links to each other with the rear end of conducting sleeve face of vulcanizer central authority, the inner catheter leading portion is placed through in the guide pin bushing of tire forming vulcanizer central authority, ring assembly is placed on the inner catheter leading portion tube wall, gland is pressed on the ring assembly front end, link to each other with the guide pin bushing front end face of vulcanizer central authority, it is characterized in that: described ring assembly has two groups, before, each one group of back is nested with spring on the inner catheter tube wall between two groups of ring assemblies.Spring can wear and tear afterwards and the radial clearance that occurs between the inner catheter by the automatic compensation sealing ring assemblies, improves the sealing reliability between inner catheter and the ring assembly.
Hard-tube Structure Of High-temperature Inner-pressure Medium In-out Pipe Of The Central Mechanism Of Tire Shaping Vulcanizer of the present invention is nested with the retainer spring seat on the inner catheter tube wall between described two groups of ring assemblies, is nested with spring on the retainer spring seat again.Add put the retainer spring seat can improve inner catheter in ring assembly to neutrality, reduce the wearing and tearing between ring assembly and the inner catheter, improve sealing reliability, can also fixed length, prevent the long-term doubling-up of spring and lost efficacy.
Hard-tube Structure Of High-temperature Inner-pressure Medium In-out Pipe Of The Central Mechanism Of Tire Shaping Vulcanizer of the present invention, described every group of ring assembly is made of V-type pressure ring, V-type graphite-seal ring and the stack of a plurality of V-seal ring.The addition graphite-seal ring can improve the lubricity between ring assembly and the inner catheter tube wall in the ring assembly, reduces the wearing and tearing between ring assembly and the inner catheter, improves sealing reliability.
Hard-tube Structure Of High-temperature Inner-pressure Medium In-out Pipe Of The Central Mechanism Of Tire Shaping Vulcanizer of the present invention is provided with two roads or two roads with upper sealing ring between the guide pin bushing of described outer tube front end tube wall and vulcanizer central authority.Can improve the sealing reliability between outer tube tube wall and the vulcanizer central authority guide pin bushing like this, avoid the leakage of heat medium.
Hard-tube Structure Of High-temperature Inner-pressure Medium In-out Pipe Of The Central Mechanism Of Tire Shaping Vulcanizer of the present invention links to each other with adjustment screw between the guide pin bushing front end face of described gland and vulcanizer central authority.Adjustment screw can be worn and torn afterwards and the radial clearance that occurs between the inner catheter by manual adjustments compensation sealing ring assemblies, improves the sealing reliability between inner catheter and the ring assembly.
