Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments:
the utility model discloses a municipal administration water supply and drainage pipe connection structure belongs to municipal works technical field, is a structure that is used for connecting between the water supply and drainage pipe, is to having improved the sealing reliability to current pipeline connection structure.
As shown in fig. 1, the pipe connection structure is used for a sealed connection between two adjacent pipes. In construction, one of the pipelines is already in a fixed installation state, and the other pipeline is in a movable adjustment state, so that two adjacent pipeline butt ends are named as a fixed end and a movable end respectively. Preferably, the fixed end is located behind the water flow direction and the movable end is located in front of the water flow direction according to the flow direction of water flow in the drainage pipeline. In fig. 1, the flow direction of the water flow is set from left to right, the left end is a fixed end, and the right end is a moving end.
As shown in fig. 2 and 3, the fixed end is a small diameter section 1, that is, a part with a diameter smaller than that of the pipe main body 7 at one end of the pipe main body 7 is called a small diameter section 1. The end face of the small-diameter section 1 is provided with a sealing groove, and an end face sealing ring 2 is embedded in the sealing groove. Correspondingly, a spigot 4 is arranged on the inner wall of the moving end, and the inner diameter of the inner spigot 4 is matched with the outer diameter of the small-diameter section 1. When the small-diameter section 1 is connected, the small-diameter section 1 extends into the inner spigot 4, and the end face seal ring 2 at the end part of the small-diameter section 1 is extruded with the inner end face of the inner spigot to realize sealing.
As shown in fig. 2, a circular boss 3 is provided at the junction of the small-diameter section 1 and the pipe main body 7. The fixed end is sleeved with a connecting sleeve 5, and the connecting sleeve 8 is used for connecting the fixed end and the movable end. The inner wall of the connecting sleeve 5 is a stepped hole, wherein the inner wall of the large-diameter hole part of the stepped hole is provided with threads, and the inner diameter of the small-diameter hole part of the stepped hole is smaller than the outer diameter of the circular boss 3.
