Description
Technical field
The utility model relates to a kind of pipe-line system, particularly a kind of telescopic feedwater impact-resistant modified polyvinyl chloride pipe-line system.
Background technique
Pipe-line system is as a kind of common liquid transporting mode, and its every aspect in real life has embodiment.Often the situation that duct length can not satisfy the demands can be there is in application process; now just need to add new pipeline; need in the connection procedure of pipeline and pipeline to add pipe fitting; thus prevent liquid outflow from causing unnecessary loss; but adopt this mode connected one by one greatly can reduce working efficiency, so design a kind of telescopic feedwater impact-resistant modified polyvinyl chloride pipe-line system just seem particularly important.
Summary of the invention
The utility model technical issues that need to address are the Liquid transfer length by regulating the connecting length of the first connecting tube and the second connecting tube to control pipe-line system, thus increase its practicability; A kind of telescopic feedwater impact-resistant modified polyvinyl chloride pipe-line system is provided.
For solving above-mentioned technical problem, structure of the present utility model comprises two first connecting tubes and second connecting tube, the second described connecting tube and the first connecting tube are all circular pipe, the diameter of the second described connecting tube is greater than the diameter of the first connecting tube, the arranged outside of the first described connecting tube has external connection screw, the inner side of the first described connecting tube connects screw thread in being provided with and matching with external connection screw, one end of two described second connecting tubes is movably connected in the second connecting tube respectively by the cooperation of screw thread, the other end of the second described connecting tube is connected with flange, also seal ring is provided with between the first described connecting tube and the second connecting tube, also protective layer is provided with in the first described connecting tube.
Further: described protective layer is the water conservancy diversion plate be obliquely installed, the inclination angle of described water conservancy diversion plate is be greater than the acute angle that 15 degree are less than 30.
Further again: in the second described connecting tube, to be provided with handle type butterfly valve.
Further again: the first described connecting tube and the second connecting tube are be made up of impact-resistant modified polyvinyl chloride (PVC-M) extrusion moulding respectively.
After adopting said structure, the utility model by the Liquid transfer length regulating the connecting length of the first connecting tube and the second connecting tube to control pipe-line system, thus can not only increase its practicability; And the design reduces liquid wearing and tearing to inner-walls of duct in course of conveying by being provided with protective coating in the inside of pipeline, thus serve the effect extending pipe-line system working life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
The telescopic feedwater impact-resistant modified polyvinyl chloride of one as shown in Figure 1 pipe-line system, comprise two first connecting tubes 2 and second connecting tube 1, the second described connecting tube 1 and the first connecting tube 2 are all circular pipe, the diameter of the second described connecting tube 1 is greater than the diameter of the first connecting tube 2, the arranged outside of the first described connecting tube 2 has external connection screw, the inner side of the first described connecting tube 2 connects screw thread in being provided with and matching with external connection screw, one end of two described second connecting tubes 1 is movably connected in the second connecting tube 1 respectively by the cooperation of screw thread, the other end of the second described connecting tube 1 is connected with flange 3, seal ring 5 is also provided with between the first described connecting tube 2 and the second connecting tube 1, also protective layer is provided with in the first described connecting tube 2, the first described connecting tube 2 and the second connecting tube 1 are be made up of impact-resistant modified polyvinyl chloride (PVC-M) extrusion moulding respectively.During work, the connecting length of the first connecting tube and the second connecting tube is first regulated according to the actual demand of Liquid transfer length, by rotating the second connecting tube 1, external connection screw is utilized to connect coordinating of screw thread with interior, regulate the first connecting tube 2 to be connected to length in the second connecting tube 1, then utilize the flange 3 being arranged on two second connecting tube 1 one end that the second connecting tube 1 and the first connecting tube 2 are connected in transporting system; The Liquid transfer length of the design by regulating the connecting length of the first connecting tube and the second connecting tube to control pipe-line system, thus increase its practicability; And the design reduces liquid wearing and tearing to inner-walls of duct in course of conveying by being provided with protective coating in the inside of pipeline, thus serve the effect extending pipe-line system working life.
Protective layer is as shown in Figure 1 the water conservancy diversion plate 6 be obliquely installed, and the inclination angle of described water conservancy diversion plate 6 is be greater than the acute angle that 15 degree are less than 30.The design is provided with the water conservancy diversion plate 6 be obliquely installed in the inner side of the first connecting tube 2, in the process of Liquid transfer, liquid can first impact water conservancy diversion plate 6, and can not cause wearing and tearing to the inwall of the first connecting tube 2; The design reduces liquid wearing and tearing to inner-walls of duct in course of conveying by being provided with protective coating in the inside of pipeline, thus serves the effect extending pipe-line system working life.
Handle type butterfly valve 4 is provided with in the second connecting tube 1 as shown in Figure 1.The design is provided with handle type butterfly valve 4 in the second connecting tube 1, can be controlled the flow of liquid in pipe-line system during work by control handle formula butterfly valve 4; The design has the advantage that structure is simple, be easy to manufacture and practicality and high efficiency.
