Abstract
The utility model relates to an inverse buckled end surface sealing swivel joint which is suitable for rotary pipelines and static pipelines. A rotor (2) is used as a fluid passage; after one end of the rotor (2) is provided with a sealing ring (10), a rotor sealing cover (9), a connecting key (11) and a stop return cushion ring (12), the rotor is screwed tightly by screw nuts (13); a supporting frame (3), springs (5), a stator sealing cover (7) and a sealing ring (8) are sheathed on the rotor (2); a casing (16) is connected with the stator sealing cover (7). The elasticity of the springs (5) and the fluid pressure are used in the swivel joint to push the stator sealing cover (7) to move to the rotor sealing cover (9) and compress the sealing ring (8) to form the rotary mechanical inverse buckled end surface seal. The phenomenon of 'buckle sliding' caused by the frequent positive and inverse turning of the rotor can be prevented effectively.
Description
The utility model belongs to a kind of swivel joint that rotating pipe and static pipeline are tightly connected that is suitable for.
Existing swivel joint technology mainly is to adopt the radial seal of two diameters between the solid of rotation of swivel joint and meront, and adopts the rubber-like nonmetallic material as Sealing, because the Sealing rapid wear then causes sealing unreliable.
The purpose of this utility model is to change the radial seal between the solid of rotation and meront in the swivel joint, by the left-hand thread end face seal and is set sealing effect and the working life that the clockwise and anticlockwise stopping device improves Sealing.
The purpose of this utility model is achieved in that the end that flanged 1 rotor (2) is placed in the housing (16) is provided with keyway (14), between rotor seal lid (9) and rotor (2), connecting key (11) is set, rotor (2) step end face is made static sealing with seal ring (10), floor clip (12) is placed between rotor seal lid (9) and the nut (13), support (3), seal stator lid (7), seal ring (8) all is enclosed within on the rotor (2), seal ring (8) is arranged between seal stator lid (7) and the rotor seal lid (9), constitute the dynamic seal (packing) of left-hand thread end face, the spring 5 that is enclosed within on the rotor (2) is placed between support (3) and the seal stator lid (7), spline key (4) is placed in the groove that support (3) seal stator lid (7) constituted, seal ring (6) is placed on housing (16) and makes static sealing with the end face that contacts of seal stator lid (7), and housing (16) tail end is provided with the interface (15) that is connected with extraneous static pipeline.Wherein seal ring (8) end face is subjected to the pressure F of sealing cover (7), (9) to be: F=f+PS
The elastic force of f---spring (5)
P---pressure by medium in the pipeline swivel joint
The basal area of S---housing (16)
Left-hand thread end face seal swivel joint described in the utility model, in dynamic seal (packing), utilize the elastic force of spring (5) and pass through hydrodynamic pressure, promote seal stator lid (7) and move, and compress seal ring (8), form the end face seal of rotatable mechanical type left-hand thread to rotor seal lid (9).Its sealing is reliable, high temperature resistant, corrosion-resistant, the life-span is long, simple in structure, easy installation and removal; Can prevent " slide fastener " phenomenon that the frequent positive and negative rotation of rotor occurs effectively.
Accompanying drawing 1 rotary joint structure figure.
The utility model is to implement like this: the rotor of swivel joint (2) is a central through bore, does the fluid passage.The flange (1) of rotor (2) one ends is connected with other rotating pipe, one end of band keyway (14) is spiral shell button shape, and load onto seal ring (10) successively at this end, rotor seal lid (9), connecting key (11), floor clip (12), and after screwing round nut (13), retaining sheet bending on the floor clip (12) is pressed in the locking trough of round nut (13), make rotor (2) suitable, when rotating counterclockwise, rotor seal lid (9) all can not withdraw from, can not rotate and the end-face seal ring that weares and teares (10) relative to rotor (2) yet, support (3), spring (5), seal stator lid (7) and seal ring (8) are enclosed within on the rotor (2), seal ring (8) is made (metallic material) with hard material, spline key (4) is placed in the spline keyway of fixed support (3) and seal stator lid (7), and support (3) can only moving linearly and can not rotate relatively to make seal stator lid (7).Housing (16) is connected to seal stator lid (7), and its contact end face is made the end face static sealing with seal ring (6), and housing (16) is provided with the interface (15) that is connected with extraneous static pipeline.Is connected with flexible pipe between extraneous static pipeline and the interface (15), housing (16) is pulled down, can nut for convenience detach (13), floor clip (12) and rotor seal cover (9), behind the connecting key (11), replacing seal ring (8).
Claims (1)
1, a kind of swivel joint by the left-hand thread end face seal, the end that the rotor (2) that it is characterized in that flanged (1) is placed in the housing (16) is provided with keyway (14), between rotor seal lid (9) and rotor (2), connecting key (11) is set, rotor (2) step end face is made static sealing with seal ring (10), floor clip (12) is placed between rotor seal lid (9) and the nut (13), support (3), seal stator lid (7), seal ring (8) is enclosed within rotor (2) and goes up and be arranged between seal stator lid (7) and the rotor seal lid (9), the spring (5) that is enclosed within on the rotor (2) is placed between support (3) and the seal stator lid (7), spline key (4) is placed on support (3), in the groove that seal stator lid (7) constitutes, the end face that contacts after seal ring (6) is placed on housing (16) and seal stator covers (7) is made static sealing.
