Description
Technical field
The invention belongs to mechanical engineering technical field, relate to a kind of self-sealing quick-changing joint and installation method.
Background technique:
In equipment such as milling train, because the requirement of producing, equipment needs often to change, its installation process is generally: earlier the milling train slide is lifted on the slide rail, traversing oil hydraulic cylinder homalocephalus is connected with the milling train slide again, by oil hydraulic cylinder milling train is moved to rolling position, the replacing process is opposite with installation.Therefore, the pipeline on the equipment such as oil gas, cooling water etc. also need often to be communicated with system pipeline and switch.For this reason, general way is the joint that adopts flexible pipe to connect, and finishes the cut-out of pipeline when equipment replacement earlier by manual operations, carries out the replacing of equipment again, when packing new equipment into, after equipment adjusted to the right place, finishes the connection of pipeline again by manual operations.It is inconvenient that this method seems when the quick replacing of equipment, and efficient is lower.In addition, the general joint that adopts does not have self sealing action, and in the cutting-off process of machine upper pipeline and system pipeline, medium residual in the pipeline can leak, extraneous impurity also can butt joint and pipeline pollute, form unnecessary waste and damage.
Summary of the invention
The present invention is a kind of self-sealing quick-changing joint and method.Solve equipment such as milling train in quick-replaceable process, machine upper pipeline and system pipeline be communicated with switch in the inefficiency of existence, the problem of leakage is arranged.Outer tube of the present invention is connected with spigot by the seal ring of spigot.Seal ring is installed by the inner tube portion of described spigot, on being responsible for, between its upper surface and person in charge outer ring, the top shoulder end face seal ring is installed by spring housing, between the inner ring and the person in charge's the outer cylinder seal ring is installed; The lower end of spring places the inside groove of cutting ferrule, and cutting ferrule and connecting plate are affixed, and the person in charge's lower end is connected with pipe joint with positioning ring.Shoulder and positioning ring and the pipe joint of the described person in charge by its outer ring, top is clamped on the connecting plate.The installation method of self-sealing quick-changing joint of the present invention is fixedly installed in described outer tube on the equipment, connects with the machine upper pipeline, forms inlet pipeline, and described spigot is by the inner ring shoulder sealing of seal ring and outer tube.Described spigot is installed on traversing oil hydraulic cylinder etc. by connecting plate and is connected with equipment on the relatively-stationary parts in position, back, and it is by pipe joint connected system pipeline.Described spigot is close with the pipe that moves outward of oil hydraulic cylinder, inner ring shoulder sealing by seal ring and outer tube, interior pipe forms Seal cage with outer tube, the fixed-site of pipe in this moment, spigot continues close to outer tube, and spring is compressed, and is responsible for outside tube side to stretching out, form the path of sealing, for the circulation of medium.During equipment such as replacing milling train, its process is opposite with installation.
The present invention is a kind of quick release coupling that can use in equipment replacing processes fast such as milling train, can improve the efficient of equipment replacement, and has self-packing effect, avoids the leakage of pipeline medium.

Among the figure, part 1 outer tube, part 2 seal rings (), pipe in the part 3, part 4 is responsible for part 5 seal rings (two), part 6 seal rings (three), part 7 springs, part 8 cutting ferrules, part 9 positioning rings, part 10 connecting plates, part 11 pipe joints, part 12 outer tubes.
Embodiment
1～5 the invention will be further described in conjunction with the accompanying drawings:
The present invention mainly comprises independently outer tube 1 and spigot; Spigot is mainly by seal ring () 2, interior pipe 3 is responsible for 4, seal ring (two) 5, seal ring (three) 6, spring 7, cutting ferrule 8, positioning ring 9, connecting plate 10 and pipe joint 11 are formed: seal ring () 2 is installed in interior pipe 3 ends, be enclosed within on the person in charge 4 by spring 7, between its upper surface and the person in charge's 4 end faces seal ring (two) 5 be installed, between the inner ring and the person in charge's 4 the outer cylinder seal ring (three) 6 is installed; The lower end of spring 7 places the inside groove of cutting ferrule 8, and cutting ferrule 8 is affixed with connecting plate 10, is responsible for 4 lower end the shaft shoulder and internal thread are set, and behind positioning ring 9 location, the outside thread by pipe joint 11 is connected with the person in charge 4 internal thread.
Interior pipe 3 is under the effect of spring 7, make its upper surface and be responsible for 4 end faces by seal ring (two) 5 sealings, its inner ring is by seal ring (three) 6 and the outer cylinder sealing of being responsible for 4, by the positioning ring 9 and the clamping force that the shoulder of being responsible for 4 is produced connecting plate 10 of centre, will be responsible for 4 and be fixed on the connecting plate 10.Being responsible for 4 shoulder and positioning ring 9 and pipe joints 11 by its outer ring, top is clamped on the connecting plate 10.
The present invention realizes by following installation method: outer tube 1 is fixedly installed on the equipment, connects with the machine upper pipeline, forms inlet pipeline, and spigot is by the inner ring shoulder sealing of seal ring () 2 with outer tube 1.In the fast installation process of equipment such as milling train, outer tube 1 is fixedly mounted on the equipment, and connection device pipeline, spigot are installed on traversing oil hydraulic cylinder etc. by connecting plate 10 and are connected with equipment on the relatively-stationary parts in position, back, and it is by pipe joint 11 connected system pipelines.Outer tube 1 wants concentric with the installation of spigot during installation, and the phase mutual edge distance is suitable.In the process that connects fast, spigot is 1 close with the pipe that moves outward of oil hydraulic cylinder, when the binding site that arrives as shown in Figure 2, by the inner ring shoulder sealing of seal ring () 2 with outer tube 1, interior pipe 3 forms Seal cage with outer tube 1, the fixed-site of pipe 3 in this moment, spigot continues close to outer tube 1, and spring 7 is compressed, being responsible for 4 stretches out to outer tube 1 direction, reach connection position as shown in Figure 3, promptly form the path of sealing, for the circulation of medium.During equipment such as replacing milling train, its process is opposite with installation, and spigot is in the process of leaving outer tube 1, because the pressuring action of spring 7 is responsible for 4 and is withdrawn into earlier in the interior pipe 3, after the formation sealing, along with the continuation of spigot is moved, interior pipe 3 separates with outer tube 1, thereby finishes the handoff procedure of pipeline.
After outer tube 1 is replaced with the form of spigot, see attached Figure 4 and 5, can form the quick release coupling structure of both-end sealing.The connecting plate 10 of socket is fixedly installed on the equipment, and pipe joint 11 is connected with the machine upper pipeline, forms inlet pipeline, and spigot is by the inner ring shoulder sealing of seal ring () 2 with outer tube 12.
Connection of the present invention and switching, all the time be under the condition of sealing, to finish, can effectively stop the leakage of system media, need not manual operation in the process, can effectively improve the replacing efficient of equipment such as milling train, can be widely used in milling train etc. needs the equipment machine upper pipeline of quick change to be communicated with and switching with the quick of system pipeline.
