Abstract
The utility model provides a pipeline connecting device, which is formed by an outer sleeve and an inner pipe, wherein the inner pipe is arranged in the outer sleeve; a sealing cushion is arranged between the outer sleeve and the inner pipe; one end of the outer sleeve is provided with a flange; and one end of the inner pipe is provided with a flange. The pipeline connecting device disclosed by the utility model has a simple structure and is convenient to use; and the retracting length can be randomly adjusted.
Description
Technical field
The utility model is specifically related to a kind of pipe jointer.
Background technique
The general conveying task that adopts some diaphragm pumps to bear mine tailing of large-scale iron ore enterprise.Every diaphragm pump outlet all is equipped with 4 64 kilograms of DN250 valves, is 1 group after 2 valve series connection, totally 2 groups.It is the short circuit of fastening flange that 2 series connected valves connect design employing two ends, this short circuit, and length can not be regulated, usually cause the pad between valve and short circuit to press bad in the replacing after valve damages, cause leakage, overhaul not only time-consumingly but also can not ensure the quality of products, have a strong impact on the operation of diaphragm pump.
Summary of the invention
The utility model provides a kind of pipe jointer of adjustable length.
The utility model is comprised of outer sleeve and inner tube, and inner tube is arranged in the outer sleeve, is provided with sealing gasket between outer sleeve and the inner tube, and an end of outer sleeve is provided with flange, and an end of inner tube is provided with flange.
The utility model is simple in structure, and is easy to use, and collapsing length can arbitrarily be regulated.
The utility model can guarantee the quick mounting valve, has guaranteed again quality.In addition, also slowed down because the impact of diaphragm pump operation is loaded on the main pipe, reduced the main pipe vibration.
Description of drawings
Fig. 1 is structural drawing of the present utility model.
Among the figure, 1, flange, 2, outer sleeve, 3, inner tube, 4, flange.
Embodiment
Embodiment: shown in Figure 1, the present embodiment is comprised of outer sleeve 2 and inner tube 3, and inner tube 3 is arranged in the outer sleeve 2, is provided with sealing gasket between outer sleeve 2 and the inner tube 3, and an end of outer sleeve 2 is provided with flange 1, and an end of inner tube 3 is provided with flange 4.
