An mpve double-wall corrugated pipe connection sealing device

Abstract

The invention discloses an MPVE double-wall corrugated pipe connection and sealing device, which belongs to the field of double-wall corrugated pipes, and comprises two corrugated pipes and two connecting frames, the two connecting frames are respectively located outside the two corrugated pipes, and the two A fixed plate is fixed on the side close to the connection frame, and a sealing ring is fixed on the side close to the two fixed plates. Both ends of the sealing ring are connected with connecting pipes, and sealing grooves are opened on both side walls of the sealing ring. The inner surfaces of the top walls of the two connection frames are symmetrically rotated and installed with a screw rod one, and the screw nut block one is threaded on the screw rod one, and the screw rod two is installed on the inner surfaces of the bottom walls of the two connecting frames. Screw nut block 2 is threadedly connected, a fixed shaft is welded between screw mandrel 1 and screw mandrel 2 on the same side, and movable rod 1 is fixed between two nut block 1; the present invention has novel design and ingenious structure, ensuring The bellows connection is tight, and it is easy to disassemble, easy to maintain and overhaul, easy to operate, and worthy of promotion.

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. [0003] In practical applications, it is necessary to connect multiple pipes together. The existing nozzle connection structure facilitates the connection between the pipes, but the disassembly is...

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
