Abstract
The utility model discloses a flexible rotating telescopic joint which comprises a link joint, a positioning ring, a limiting bolt, a positioning flange, an outer sleeve and an inner sleeve, wherein the link joint and the positioning ring are welded together through welding; the link joint and the positioning ring are welded on the inner sleeve; the positioning flange is welded on the outer sleeve; the limiting bolt is connected between the link joint and the positioning flange; and the outer sleeve and the inner sleeve are fixedly connected through a hold-down nut. According to the flexible rotating telescopic joint, under the condition of not influencing the pump testing requirement and the performance data measurement, in order to solve the industrial problems that a closed test-bed pump testing pipeline is rigid, so that the time cost is too high, the economic cost is too high, and the pump testing tubings are too large in number, and the pump testing working efficiency is low, the flexible rotating telescopic joint is researched to ensure the return circuit to be stable as far as possible, the pump testing pipeline connection time is shortened, and the pump testing efficiency is improved.
Description
Technical field
The utility model 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 working as by the pump testing location positioning in common pump testing process, 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 even the welded tube road is joined at the scene, 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.
The model utility content
The purpose of this utility model is to provide a kind of shortening pump testing pipeline connect hours, improves the flexible rotating expansion pipe joint of pump testing efficient.
the technological scheme that the utility model 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 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).
Described caging bolt (5) is connected on link joint (3) by bolt (1) and nut (2).
Be provided with rubber seal (8) between described gland nut (9) and outer sleeve (7).
A kind of flexible rotating expansion pipe joint of the utility model, in the situation that do not affect pump testing requirement and performance data measurement, 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, our research and model utility gentle flexible rotating expansion pipe joint device, guarantee that as far as possible the loop stablizes, 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 utility model.
In 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
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 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, be provided with rubber seal 8 between gland nut 9 and outer sleeve 7, this structure adopts slidably inside and outside sleeve, it can be the form of two end flange or end flange one an 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 locating flange 6 is pulled out caging bolt 5, import and export according to tested pump the length that distance is adjusted inside and outside sleeve, 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 use 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 until entry end the flexible rotating expansion pipe joint locking that will soften after complete with tested pump testing.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 hommization more of its operating process.
