Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As depicted in figs. 1 and 2, for the ball compensator that pipeline connects, comprise preceding pipeline 1 and the rear flange 3 of inner connection, the prepass 11 of preceding pipeline 1 is connected with the rear passage 13 in rear flange 3.Spherical Seals circle 6 is provided with between preceding pipeline 1 and the connecting end surface of rear flange 3.Preceding pipeline 1 is provided with the flange 12 that external diameter is greater than preceding pipeline 1 pipe diameter, and the connecting end surface of preceding pipeline 1 is arranged on flange front end face 121.And flange front end face 121 is designed to the sphere suitable with Spherical Seals circle 6 shape, ensure that preceding pipeline 1 is in generation axis oscillating formula, also effectively can reach sealing between flange front end face 121 and Spherical Seals circle 6.
Forward flange 2 is outside equipped with at preceding pipeline 1, and seal ring 7 before being provided with between forward flange 2 and the rear end 122 of above-mentioned flange 12.Adopt fastening piece 5 to be connected between forward flange 2 with rear flange 3 and ensure the pretightening force of Spherical Seals circle 6, realizing sealing.
Because the height of this compensator is just mainly subject to forward flange 2, rear flange 3 and Spherical Seals circle 6, the height impact of seal ring 7 before rear, therefore, it is possible to effectively reduce integrally-built height, be particularly suitable for position compact, the working environment that installing space is little uses.
Radial clearance 9 after simultaneously having between forward flange 2 and the outer wall of flange 12, has front radial clearance 91, has certain space when preceding pipeline 1 is swung between preceding pipeline 1 and forward flange 2.
In order to reduce the impact of working environment on Spherical Seals circle 6 and front seal ring 7, sleeve 4 is provided with between forward flange 2 and rear flange 3, also leave rear radial clearance 9 between the outer rim of sleeve 4 inwall and flange 12, Spherical Seals circle 6 and front seal ring 7 are arranged in the enclosed space in sleeve 4.Arranging of sleeve 4 can adopt various ways, prevent the skew of sleeve 4, and make it can not interfere when preceding pipeline 1 swings, as one, at least one in forward flange 2 with rear flange 3 is provided with seam 10, and above-mentioned sleeve 4 is arranged in above-mentioned seam 10.Seam 10 can be arranged on forward flange 2 or rear flange 3, also on forward flange 2 with rear flange 3, can arrange seam as shown in Figure 3, they two simultaneously, as described in Figure 2, sleeve 4 and forward flange 2 are structure as a whole, and are provided with seam 10 on rear flange 3, and sleeve 4 is arranged in seam 10.In like manner, also can be processed as one sleeve 4 and rear flange 3 structure, and forward flange 2 arranges seam.Arranging in the structure of sleeve above-mentioned, by controlling the size of sleeve 4, ensureing the decrement that the generation of Spherical Seals circle 6 and front seal ring 7 is suitable to reach the control of pretightening force.In addition in order to prevent due to Spherical Seals circle 6 wear and tear or damage time, the leakage of liquid, the installation end face of sleeve 4 is provided with sleeve seal circle 41, even if such liquid is leaked in rear radial clearance 9, sleeve seal circle 41 and front seal ring 7 also can effectively prevent liquid to be leaked to outside compensator from the end face of sleeve 4.
As shown in Figure 2, the outer rim of flange 12 is provided with annular boss 8, the diameter of above-mentioned annular boss 8 and the internal diameter adaptation of sleeve 4, namely minimum gap is left between annular boss 8 and sleeve 4, and annular boss 8 is very little with the contact height of sleeve 4, make preceding pipeline 1 radial displacement can not occur, but rear flange 3, forward flange 2 swing, and allow annular boss 8 to move up and down relatively to allow preceding pipeline 1.Due in installation and using process, the axial displacement between preceding pipeline 1 and rear flange 3 may be there is, so have employed two ring structures of Spherical Seals circle 6 and front seal ring 7, because these two seal rings are the rubber seal with resiliently deformable, there is the elastic deformation amount of about 5% ~ 10%, so when Spherical Seals circle 6 and front seal ring 7 have certain altitude, corresponding amount of deformation just can be provided to meet the needs of preceding pipeline 1 axial displacement.
As shown in Figure 4, the periphery that flange 12 is corresponding with sleeve 4 is set to polygonal, and namely preceding pipeline 1 is outer polygonal 123, and sleeve 4 is inner polygon 42, like this when allowing preceding pipeline 1 to have certain pendulum angle, limit preceding pipeline 1 the relatively rotating of forward flange 2 and sleeve 4 relatively.Its polygonal is preferably the polygonal on 6 ~ 12 limits.
In order to both meet the swing of preceding pipeline 1, limit the rotation of preceding pipeline 1 again, therefore as shown in Figure 4, the outer rim of flange 12 is divided into two sections, one section arranges annular boss 8, and one section is processed as outer polygonal 123.
In said structure, described preceding pipeline 1 and the mark of rear flange 3 just with reference to the accompanying drawings done by layout, in as installed and using process, its mutual context can change.Simultaneously according to the use at scene, for pipeline or front and back are the structure of flange before and after can also adopting, also object of the present invention can be reached.
