Description
Technical field
The utility model relates to a kind of component of producing pneumatic tyre or solid tyre, especially a kind of Quick Connect Kit of vulcanizer mold pressure duct.
Background technique
At present, tire mold advances with cycle of higher pressure, water return pipeline all adopts flange plate to be connected, and an asbestos washer is set between flange plate.Due to the erosion of high temperature, steam, mold cleaner, the clamping bolt of mounting flange easily produces corrosion, and when more mold exchange carried out the dismounting of cycle of higher pressure pipeline, clamping bolt must adopt the gas cutting mode to process at every turn, and asbestos packing and flange contact facings cleaning difficulty.When changing operation, miantainers need to creep into high temperature, be covered with and carry out below the very narrow support of pipeline, change that a vulcanizer mold cycle of higher pressure is advanced, water return pipeline connects needs approximately 3 hours consuming time, exists that labor strength is large, inefficiency, deficiency that maintenance cost is high.In addition, the asbestos washer leakage prevention capability is poor, and the mounting flange place easily produces leakage.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of Quick Connect Kit of simple in structure, labor strength is low, more mold exchange dismounting cycle of higher pressure pipeline speed is fast, maintenance cost is low vulcanizer mold pressure duct.
the technological scheme that its technical problem that solves the utility model adopts is: a kind of Quick Connect Kit of vulcanizer mold pressure duct, it is characterized in that: it comprises a hollow pipe fitting body, one slip-knot nut and a hollow conduit joint, an end end at described hollow pipe fitting body is shaped with a connection chamber, the other end is shaped with the external connecting screw thread, make six sides at the intermediate portion of hollow pipe fitting body outer surface and revolve body, one end of described hollow conduit joint is shaped with the connection chamfering, the other end end is provided with annular boss, the hollow conduit joint connects in the closing in of this annular boss and described slip-knot nut afterbody, and be connected on described hollow pipe fitting body through the slip-knot nut thread, be provided with a tetrafluoroethylene sealing gasket between hollow pipe fitting body and hollow conduit joint, described hollow pipe fitting body is welded on the mould pipeline through its connection chamber, described hollow conduit joint connects chamfering through it and is welded on steam pipework.
The utility model is due to welding one hollow pipe fitting body on the mould pipeline, welding one hollow conduit joint on steam pipework, connect in the annular boss of hollow conduit joint the other end setting and the closing in of a slip-knot nut afterbody, the hollow conduit joint is connected on the hollow pipe fitting body through the slip-knot nut thread, is provided with a tetrafluoroethylene sealing gasket between hollow pipe fitting body and hollow conduit joint.The utility model connects flange plate of the prior art changes into the slip-knot connection, and it is simple in structure; Hollow pipe fitting body, slip-knot nut and hollow conduit joint adopt stainless steel, high temperature, steam and mold cleaner be difficult for to produce corrosion to it, more convenient disassembly is quick during mold exchange, have saved the operation of gas cutting, polishing, alleviate workman's labor intensity, reduced maintenance cost; The leakage-preventing performance of tetrafluoroethylene sealing gasket is good, and the joint is difficult for producing leaks.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a kind of structure sectional view of the present utility model.
