Abstract
The invention provides a seal pipe joint for PP pipes. The seal pipe joint comprises a main joint body and joint covers, wherein the main joint body is connected with the joint covers through screw threads; a seal ring is arranged on the main joint body, and sealing layers are arranged on the joint covers. The PP pipe enters a channel of the main joint body from PP pipe through holes in the joint covers at the two ends of the main joint body and is butted against on limiting rings in the through holes, and the joint covers are started to be screwed; after the joint covers are screwed, the sealing layers are pressed to deform and close to the outer pipe wall of the PP pipe; a first sealing end covers a seal groove, and the seal ring in the seal grove deforms and is closely fitted with the inner wall of the first sealing end. The seal pipe joint has the advantages of being simple in structure, reasonable in design, easy to connect and convenient to mount and dismount, realizes the connection of the PP pipes, and ensures the sealing performance of PP pipe connection. The sealing performance of the main joint body and the joint cover is improved, external sewage is prevented from entering the pipe joint, and the inner components of the pipe joint are not polluted and corroded.
