Abstract
The invention discloses a flexible rotating retractable pipe joint which comprises chaining joints, locating rings, spacing bolts, locating flanges, outer sleeves and inner sleeves, wherein the chaining joints and the locating rings are welded and fixed together; the chaining joints and the locating rings are welded on the inner sleeves, and the locating flanges are welded on the outer sleeves; and the spacing bolts are respectively connected between the chaining joints and the locating flanges, and the outer sleeves and the inner sleeves are fixedly connected through gland nuts. The flexible rotating retractable pipe joint provided by the invention has the advantages that the industry difficult problems the time cost is high and the economic cost is high caused by the hardness connection of a closed type test bed testing pump pipeline, testing pump branch pipes are excessive and the work efficiency of a testing pump is low are solved; and a flexible rotating retractable pipe joint device is researched and invented by people, so that the stableness of a loop is guaranteed as far as possible, the testing pump pipeline connecting time is shortened, and the efficiency of the testing pump is improved.
Description
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 after in common pump testing process, working as by the pump testing location positioning, its pump advances, advancing of water outlet and water storage tank, water outlet is to form by the pipe arrangement rigid connection, because the pump product standard and type is more, so enterprise has to prepare a large amount of different bores in order to improve pump testing efficient, the different pressures grade, the pump testing pipeline section of unequal length reaches the purpose of pump testing, sometimes in addition the scene join the welded tube road, this has just increased the difficulty of production unit in various pipe arrangement operation and use of pump, certainly also can cause managerial confusion, and cause cost of production to strengthen the pump testing inefficiency.
Summary of the invention
The purpose 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 efficient.
The technological scheme that the present invention adopts 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), described link joint (3) is welded and fixed together with positioning ring (4), link joint (3) is welded on the inner sleeve (10) with positioning ring (4), locating flange (6) is welded on the outer sleeve (7), caging bolt (5) is connected between link joint (3) and the locating flange (6), and outer sleeve (7) is fixedly connected with by gland nut (9) with inner sleeve (10).
Described caging bolt (5) is connected on the link joint (3) by bolt (1) and nut (2).
Be provided with rubber seal (8) between described gland nut (9) and the outer sleeve (7).
A kind of flexible rotating expansion pipe joint of the present invention, in the situation that does not affect the measurement of pump testing requirement and performance data, 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 pump testing pipe arrangement too much reaches the low professional difficult problem of pump testing working efficiency, and we study and have invented gentle flexible rotating expansion pipe joint device, guarantees that as far as possible the loop is stable, shorten the pump testing pipeline connect hours, improve pump testing efficient.

Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is that the B of Fig. 1 is to view.
Fig. 4 is the use view of a kind of flexible rotating expansion pipe joint of the present invention.
Among the figure: 1, bolt; 2, nut; 3, link joint; 4, positioning ring; 5, caging bolt; 6, locating flange; 7, outer sleeve; 8, rubber seal; 9, gland nut; 10, inner sleeve.
Embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, the 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, link joint 3 is welded and fixed together with positioning ring 4, link joint 3 is welded on the inner sleeve 10 with positioning ring 4, locating flange 6 is welded on the outer sleeve 7, caging bolt 5 is connected between link joint 3 and the locating flange 6, outer sleeve 7 is fixedly connected with by gland nut 9 with inner sleeve 10, caging bolt 5 is connected on the link joint 3 by bolt 1 and nut 2, be provided with rubber seal 8 between gland nut 9 and the outer sleeve 7, this structure adopts slidably inside and outside sleeve, it can be the form of two end flange or an end flange one end welding (deciding as required) that inside and outside sleeve is connected with pipeline, the concrete use operates: the nut side direction of unclamping on the locating flange 6 is pulled out caging bolt 5, import and export the length that distance is adjusted inside and outside sleeve according to tested pump, install rear rotation gland nut 9 until pipeline and make 8 reaches of cone rubber seal ring, seal ring makes its internal diameter of the seal ring and inner sleeve 10 compress in the process of reach under the inner conical surface reaction force at outer sleeve 7, then pushing to caging bolt 5 usefulness hands gets final product nut screwing clamping, the upper lower nut effect of caging bolt 5 is that the restriction inside and outside sleeve produces displacement under interior pressure or external load, in general pump testing process, because suction pressure is very little, at suction port this device is installed and is cancelled caging bolt.
As shown in Figure 4, we can see the basic mode that pipeline connects on enclosed pump testing platform, at first measure tested pump-foot to the entrance point center height, then rotation adjustment crank throw makes itself and pump inlet end reach same height, if pump inlet end substantially horizontal needs to adjust, the gentle flexible rotating expansion pipe joint locking device that can unclamp near pump intake one side carries out Level tune to it, reaching our needed length, be connected the flexible rotating expansion pipe joint locking that to soften after complete with tested pump testing until entry end.Mounting type and the entrance point of outlet end are basic identical, only caging bolt need to be pushed to nut screwing clamping and be got final product, nearly 1 year operation proof, gentle flexible rotating expansion pipe joint is in conjunction with other structures, and the lifting device of auxiliary phase adaptation, solved the difficult problem that enclosed pump testing platform system pipe arrangement too much reaches professional under the pump testing inefficiency, pump testing efficient improves more than 5 times, the convenient, fast more hommization of its operating process.
