Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as Figure 1-3 As shown, the anti-blocking pipe joint system of building sewer pipes includes an anti-blocking pipe joint device and an air pressure dredging device; the anti-blocking pipe joint device includes a corner connecting pipe 1; the corner connecting pipe is composed of a water inlet elbow and an outlet elbow. Connection composition; the corner connecting pipe is formed by concentrically setting the inner elastic tube core 3 and the outer hard package tube 4; at the bottom of the water inlet elbow, the hard package tube and the elastic tube core extend downward to dredge the outlet 5; the hard sealing ring 6 is set on the hard sealing tube and the elastic tube core at the top of the water inlet elbow, the tail end of the water outlet elbow and the tail end of the dredging outlet; the space between the hard packag...

Abstract

The invention discloses an anti-blocking pipe joint system for building sewer lines. The anti-blocking pipe joint system comprises an anti-blocking pipe joint device and a pneumatic dredging device; dredging outlets on the right end, upper end and lower end of a corner connecting pipe, a hard packaging pipe and an elastic pipe core are respectively sealed by a hard seal ring; the cavity between the hard packaging pipe and the elastic pipe core is a pneumatic control cavity; the outer wall of the hard packaging pipe is fixedly provided with a control pipe which communicates with the pneumatic control cavity; the control pipe is provided with a switch valve; the pneumatic dredging device comprises a packaging shell, a piston barrel and a drive motor which are installed in the packaging shell, a transmission case connected with an output end of the drive motor, and an inertia wheel connected with an output end of the transmission case; the right end of the piston barrel communicates with a gas conduction pipe; and the other end of the gas conduction pipe and the control valve form a flexible seal fit. The internal diameter can be changed through the retraction and expansion of the elastic pipe core on the inner layer, thereby being beneficial to the movement of the deposited foreign matters at the corner, reducing the blockage probability and greatly reducing the dredging resistance.

Description

technical field [0001] The invention relates to the technical field of building pipelines, in particular to a sewer blockage prevention pipe joint system. Background technique [0002] At present, the sewer pipes used in buildings often use hard and corrosion-resistant plastic pipes. When the sewer pipes are blocked, various dredging equipment are used to dredge them, and the structure of the sewer pipes itself focuses on design. A single improved sewer dredging device cannot fundamentally solve the problem. [0003] In fact, the blockage of sewer pipes basically occurs in places with corners, because deposition, adhesion, and debris collection are prone to occur at corners, and this situation will not occur in relatively straight pipes. Therefore, for sewer pipes The design of pipeline anti-blocking should focus on improving the position of the corner of the sewer pipeline. Contents of the invention [0004] The technical problem to be solved by the present invention is...
