Polyvinyl chloride joint

Abstract

The invention relates to a pipe joint, in particular to a polyvinyl chloride joint for connecting a water tank with a heat pipe of a solar water heater. The body of the joint is divided into two parts, wherein one part is formed by welding plug parts and a heat pipe; and the other part is composed of clamp rings, steel balls, clamp sleeves, compression springs, seal rings and adaptor parts and can be welded with the water tank of the solar water heater or connected with the water tank by screwing a screw thread. When the clamp sleeves are pushed leftwards by external force, a plurality of steel balls slide out of the taper holes of the adaptor parts, the plug parts can be inserted, the external force on the clamp sleeves is removed and the compression springs reset to ensure the steel balls to be stuck in the semi-circular grooves of the plug parts so that the plug parts and the adaptor parts press the seal rings tightly to have sealing effects to ensure the water in the water tank not to leak during operation, and the plug parts can be pulled out when the steel balls slide out of the taper holes of the adaptor parts, thus ensuring convenient, quick, safe and reliable assembly and disassembly of the water tank and the heat pipe of the whole solar water heater.

Description

technical field [0001] The invention relates to a pipe joint, which is a quick-change pipe joint for a heat pipe, in particular a polyvinyl chloride joint pipe fitting for connecting a water tank of a solar water heater and a heat pipe. Background technique [0002] At present, there are two main ways to cooperate heat pipes and water tanks in the solar energy industry: (1) use screw connection, this connection method has high heat collection and heat transfer efficiency, but it requires a lot of labor during installation, and it is not convenient for workers to install at high altitude; (2) The heat conduction sleeve is used for connection. This connection method is more convenient to install, but a heat conduction resistance is added between the heat pipe and the water, which affects the effective light-to-heat conversion of solar energy to a certain extent. [0003] How to design a connection method that can quickly install the heat pipe and ensure the direct contact betw...
