Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, be used for the ball compensator that pipeline connects, comprise preceding pipeline 1 and the rear flange 3 of internal communication, the prepass 11 of preceding pipeline 1 is connected with back passage 13 in the rear flange 3.Between the connection end face of preceding pipeline 1 and rear flange 3, be provided with ball-type seal ring 6.Preceding pipeline 1 is provided with external diameter greater than the flange 12 of preceding pipeline 1 pipe diameter, and the connection end face of preceding pipeline 1 is arranged on the flange front end 121.And flange front end 121 is designed to the sphere suitable with ball-type seal ring 6 shapes, guarantee that preceding pipeline 1 in that the axis swing type takes place, also can effectively reach sealing between flange front end 121 and the ball-type seal ring 6.
Be outside equipped with forward flange 2 at preceding pipeline 1, and seal ring 7 before between the rear end 122 of forward flange 2 and above-mentioned flange 12, being equipped with.Adopt fastening piece 5 to be connected and to guarantee the pretightening force of ball-type seal ring 6 between forward flange 2 and the rear flange 3, realization seals.
Because the height of this compensator just mainly is subjected to forward flange 2, rear flange 3 and ball-type seal ring 6, the effect of altitude of seal ring 7 before the back, therefore can effectively reduce integrally-built height, be particularly suitable for the position compactness, the working environment that installing space is little uses.
Simultaneously back radial clearance 9 is arranged between the outer wall of forward flange 2 and flange 12, preceding radial clearance 91 is arranged between preceding pipeline 1 and the forward flange 2, certain space is arranged when making preceding pipeline 1 swing.
In order to reduce working environment to the influence of ball-type seal ring 6 and preceding seal ring 7, between forward flange 2 and rear flange 3, be provided with sleeve 4, also leave back radial clearance 9 between the outer rim of sleeve 4 inwalls and flange 12, ball-type seal ring 6 and preceding seal ring 7 are installed in the enclosed space in the sleeve 4.Arranging of sleeve 4 can be adopted multiple mode, prevent the skew of sleeve 4, and it can not be interfered when preceding pipeline 1 swing, as one, in forward flange 2 and the rear flange 3 at least one is provided with seam 10, and above-mentioned sleeve 4 is installed in the above-mentioned seam 10.Seam 10 can be arranged on forward flange 2 or the rear flange 3, also can on forward flange 2 and rear flange 3 seam be set simultaneously as shown in Figure 3, they are two years old, as described in Figure 2, sleeve 4 is structure as a whole with forward flange 2, and rear flange 3 is provided with seam 10, and sleeve 4 is installed in the seam 10.In like manner, the structure that also sleeve 4 and rear flange 3 can be processed as one arranges seam at forward flange 2.In the above-mentioned structure that sleeve is set, by the size of control sleeve 4, guarantee the suitable decrement of generation of ball-type seal ring 6 and preceding seal ring 7, reach the control of pretightening force.In addition in order to prevent because ball-type seal ring 6 wearing and tearing or when damaging, the leakage of liquid, the installation end face of sleeve 4 is provided with sleeve seal circle 41, even liquid is revealed and entered in the radial clearance 9 of back like this, sleeve seal circle 41 and preceding seal ring 7 can prevent effectively that also liquid is leaked to the compensator outside 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 internal diameter of the diameter of above-mentioned annular boss 8 and sleeve 4 is adaptive, be to leave minimum gap between annular boss 8 and the sleeve 4, and annular boss 8 is very little with the contact height of sleeve 4, make preceding pipeline 1 radial displacement can not take place, but allow preceding pipeline 1 relative rear flange 3, forward flange 2 to swing, and allow annular boss 8 to move up and down.Because in installation and using process, axial displacement between preceding pipeline 1 and the rear flange 3 may take place, so adopted two ring structures of ball-type seal ring 6 and preceding seal ring 7, because these two seal rings are the rubber seal with resiliently deformable, has the elastic deformation amount about 5%～10%, so have under the situation of certain altitude at ball-type seal ring 6 and preceding seal ring 7, just can provide corresponding amount of deformation to satisfy the needs of preceding pipeline 1 axial displacement.
As shown in Figure 4, flange 12 and sleeve 4 corresponding peripheries are set to polygonal, and namely preceding pipeline 1 is outer polygonal 123, and sleeve 4 is inner polygon 42, allowing preceding pipeline 1 to have under the situation of certain pendulum angle, limited relatively rotating of preceding pipeline 1 relative forward flange 2 and sleeve 4 like this.Its polygonal is preferably the polygonal on 6～12 limits.
In order both to satisfy 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 8, one sections of annular boss and is processed as outer polygonal 123.
In said structure, described preceding pipeline 1 and rear flange 3 are just arranged the mark of having done with reference to the accompanying drawings, and in as installed and using process, its mutual context can change.According to the use at scene, be that pipeline or front and back are the structure of flange before and after can also adopting simultaneously, also can reach purpose of the present invention.
