The invention discloses a kind of flexible rotating expansion pipe joint, comprise link joint, positioning ring, caging bolt, locating flange, outer sleeve and inner sleeve, together with described link joint is welded and fixed with positioning ring, link joint and positioning ring are welded on inner sleeve, locating flange is welded on outer sleeve, caging bolt is connected between link joint and locating flange, and outer sleeve is fixedly connected with by gland nut with inner sleeve.A kind of flexible rotating expansion pipe joint of the present invention, when not affecting pump testing requirement and performance data measures, too high in order to solve the time cost that closed loop test-bed pump testing pipeline rigid connection causes, financial cost is too high, the professional difficult problem that pump testing pipe arrangement is too much and pump testing working efficiency is low, we study and have invented flexible rotating expansion pipe joint device, ensure loop stability as far as possible, shorten the pump testing pipeline connect hours, improve pump testing efficiency.

Description

Flexible rotating expansion pipe joint
Technical field
The present invention relates to a kind of flexible rotating expansion pipe joint.
Background technique
In enclosed pump testing platform system, water storage tank water intake and water outlet pipeline are relatively-stationary, so in usual pump testing process after being determined by pump testing position, its pump enters, entering of water outlet and water storage tank, water outlet forms by pipe arrangement rigid connection, because pump product standard and type is more, so enterprise has to prepare a large amount of different bore to improve pump testing efficiency, different pressures grade, the pump testing pipeline section of unequal length reaches the object of pump testing, sometimes even welded tube road is joined at scene, this adds increased the difficulty of production unit in various pipe arrangement operation and use of pump, certainly also managerial confusion can be caused, and cause cost of production to strengthen, pump testing inefficiency.
Summary of the invention
The object of this invention is to provide a kind of shortening pump testing pipeline connect hours, improve the flexible rotating expansion pipe joint of pump testing efficiency.
The technological scheme that the present invention is adopted for achieving the above object is: a kind of flexible rotating expansion pipe joint, comprise link joint (3), positioning ring (4), caging bolt (5), locating flange (6), outer sleeve (7) and inner sleeve (10), together with described link joint (3) is welded and fixed with positioning ring (4), link joint (3) and positioning ring (4) are welded on inner sleeve (10), locating flange (6) is welded on outer sleeve (7), caging bolt (5) is connected between link joint (3) and locating flange (6), outer sleeve (7) is fixedly connected with by gland nut (9) with inner sleeve (10).
Described caging bolt (5) is connected in link joint (3) by bolt (1) and nut (2).
Cone rubber seal ring (8) is provided with between described gland nut (9) and outer sleeve (7).
A kind of flexible rotating expansion pipe joint of the present invention, when not affecting pump testing requirement and performance data measures, too high in order to solve the time cost that closed loop test-bed pump testing pipeline rigid connection causes, financial cost is too high, the professional difficult problem that pump testing pipe arrangement is too much and pump testing working efficiency is low, we study and have invented soft flexible rotating expansion pipe joint device, ensure loop stability as far as possible, shorten the pump testing pipeline connect hours, improve pump testing efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of flexible rotating expansion pipe joint of the present invention.
Fig. 2 is the A direction view of Fig. 1.
Fig. 3 is the B direction view of Fig. 1.
Fig. 4 is the using state schematic diagram of a kind of flexible rotating expansion pipe joint of the present invention.
In figure: 1, bolt; 2, nut; 3, joint is linked; 4, positioning ring; 5, caging bolt; 6, locating flange; 7, outer sleeve; 8, cone rubber seal ring; 9, gland nut; 10, inner sleeve.
Embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3, flexible rotating expansion pipe joint, comprise link joint 3, positioning ring 4, caging bolt 5, locating flange 6, outer sleeve 7 and inner sleeve 10, together with link joint 3 is welded and fixed with positioning ring 4, link joint 3 is welded on inner sleeve 10 with positioning ring 4, locating flange 6 is welded on outer sleeve 7, caging bolt 5 is connected between link joint 3 and locating flange 6, outer sleeve 7 is fixedly connected with by gland nut 9 with inner sleeve 10, caging bolt 5 is connected on link joint 3 by bolt 1 and nut 2, cone rubber seal ring 8 is provided with between gland nut 9 and outer sleeve 7, this structure adopts slidably inside and outside sleeve, it can be the form that (determining as required) is welded in two end flange or end flange one end that inside and outside sleeve is connected with pipeline, concrete use operates: unclamp the nut side direction pull-out caging bolt 5 on locating flange 6, the length that distance adjusts inside and outside sleeve is imported and exported according to tested pump, rotating gland nut 9 after treating Pipe installing makes cone rubber seal ring 8 move forward, under the inner conical surface reaction force of cone rubber seal ring at outer sleeve 7 in the process of reach, cone rubber internal diameter of the seal ring and inner sleeve 10 are compressed, then push to caging bolt 5 with hand, nut to be tightened, the upper lower nut effect of caging bolt 5 is that restriction inside and outside sleeve produces displacement under interior pressure or external load, because suction pressure is very little in general pump testing process, at suction port, this device is installed and can cancels caging bolt.
As shown in Figure 4, we can see the basic mode that pipeline connects on enclosed pump testing platform, first tested pump-foot is measured to entrance point center height, then rotating adjustment crank throw makes it reach same height with pump inlet end, if pump inlet end substantially horizontal needs adjustment, the soft flexible rotating expansion pipe joint locking device that can unclamp near pump intake side carries out Level tune to it, to reach the length required for us, treat that soft flexible rotating expansion pipe joint is locked after being connected with tested pump testing by entry end.The mounting type of outlet end is substantially identical with entrance point, only need caging bolt to be pushed to nut screwing clamping, within nearly 1 year, run and prove, soft flexible rotating expansion pipe joint is in conjunction with other structures, and the lifting device that auxiliary phase adapts to, solve a difficult problem for enclosed pump testing platform system pipe arrangement professional too much and under pump testing inefficiency, pump testing efficiency improves more than 5 times, the convenient, fast hommization more of its operating process.
