MPVE double-wall corrugated pipe connecting and sealing device

Abstract

The invention discloses an MPVE double-wall corrugated pipe connecting and sealing device, and belongs to the field of double-wall corrugated pipes. The MPVE double-wall corrugated pipe connecting andsealing device comprises two corrugated pipes and two connecting frames, wherein the two connecting frames are separately positioned on the outer parts of the two corrugated pipes; the sides, close to each other, of the two connecting frames are fixedly equipped with fixed plates; the sides, close to each other, of the two fixed plates are fixedly equipped with sealing rings; the two ends of thesealing rings are connected with connecting tubes; sealing slots are formed in the two side walls of the sealing rings; the inner surfaces of the top walls of the two connecting frames are symmetrically and rotatably equipped with lead screws I; the lead screws I are in threaded connection with nut blocks I; the inner surfaces of the bottom walls of the two connecting frames are symmetrically androtatably equipped with lead screws II; the lead screws II are in threaded connection with nut blocks II; a fixed shaft is welded between the lead screw I and the lead screw II at the same side; and amovable rod I is fixedly arranged between the two nut blocks I. The MPVE double-wall corrugated pipe connecting and sealing device is novel in design, is delicate in structure, guarantees connectingsealing property of the corrugated pipes, is convenient to dismount, is convenient to maintain and overhaul, is simple to operate, and is worthy of being popularized.

Description

technical field [0001] The invention belongs to the technical field of double-wall corrugated pipes, in particular to an MPVE double-wall corrugated pipe connecting and sealing device. Background technique [0002] MPVE double-wall corrugated pipe is made of polyvinyl chloride and polyethylene, which is stronger than HDPE double-wall corrugated pipe, stronger in compression resistance, lighter in weight and longer in service life. Corrugated pipe products are of great significance to the development of double-wall corrugated pipes, and can save materials by 20-25% and reduce costs by 10-25%. They are suitable for rainwater and sewage pipes and low-pressure rural irrigation pipes, etc., with excellent performance and relative economy The cost has been greatly promoted and applied.

Problems solved by technology

[0003] In practical applications, it is necessary to connect multiple pipes together. The existing nozzle connection structure facilitates the connection between pipes, but the disassembly and assembly are not convenient enough. The connection structure needs to be disassembled during daily maintenance and overhaul, but disassembly Inconvenient installation affects the efficiency of maintenance, time-consuming and labor-intensive
