Pipe connection structure and manifold

Abstract

The invention relates to a tubular product connecting structure and a water dividing and collecting device. The tubular product connecting structure comprises a core body, a steel ball clamp spring mechanism, a tubular clamp spring and a sealing sleeve. An annular groove is formed in the outer wall of the core body, and is formed in one end close to an outlet of a core body; the sealing sleeve is arranged on the core body in a sleeving manner, and the sealing sleeve is located in the annular groove; a convex blocking body which stretches out in the radial direction of the sealing sleeve is arranged at one end, far away from the outlet of the core body, of the sealing sleeve, and at least one anti-slide rib is arranged on the outer wall of the sealing sleeve; the steel ball clamp spring mechanism is arranged on the core body in a sleeving manner and is detachably connected with the core body; and the tubular clamp spring is arranged between the core body and the steel ball clamp spring mechanism in a sleeved manner. The inner wall of the tubular product is in contact with the outer wall of the sealing sleeve to form radial seal, and the end face of the tubular product abuts against the convex blocking body of the sealing sleeve to form axial seal, so that double seal is achieved between the tubular product and the core body; and the anti-slide ribs are arranged on the outer wall of the sealing sleeve, so that tubular product sliding is avoided, and the further sealing effect is achieved.

Description

technical field [0001] The invention relates to pipe connection technology, in particular to a pipe connection structure and a sub-collector. Background technique [0002] The sub-collector refers to the device used to connect the main heating water supply pipe and the return pipe in the floor heating system, which is divided into two parts: the water separator and the water collector. The water distributor is a water distribution device used to connect the water supply pipes of various heating pipes in the water system, and the water collector is a water collection device used to connect the return pipes of various heating pipes in the water system. The traditional method of connecting the manifold to the pipe is generally a press type or a plug-in type. In order to achieve a sealing effect, a sealing ring is set on the core of the manifold, but the sealing effect of the sealing ring is limited and there is leakage. risks of.
