Novel overflow pipe for solar water heater

Abstract

The invention relates to the technical field of overflow pipes, and in particular relates to a novel overflow pipe for a solar water heater, comprising a water inlet and outlet pipe and a mounting pipe in screwed connection with the water inlet and outlet pipe, wherein one end, which is in screwed connection with the mounting pipe, of the water inlet and outlet pipe, is provided with a first external thread, one end, which is in screwed connection with the water inlet and outlet pipe, of the mounting pipe, is provided with a first internal thread, the first external thread and the first internal thread are matched, one end, which is in screwed connection with the water inlet and outlet pipe, of the mounting pipe, is provided with a groove, and the other end of the mounting pipe is provided with a second external thread and a second internal thread respectively. According to the novel overflow pipe for the solar water heater, the novel overflow pipe mainly comprises the water inlet and outlet pipe and the mounting pipe, the water inlet and outlet pipe and the mounting pipe are in screwed connection, the structure is stable and firm, a sealing effect is good, a traditional welding mode for connection is avoided, the defect during welding is overcome, the assembling efficiency is improved, the production cost is reduced and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of overflow pipes, in particular to a novel overflow pipe for solar water heaters. Background technique [0002] At present, the existing overflow pipes used for water level warning of solar water heaters are welded overflow pipes, and the water inlet and outlet pipes are fixed to the installation pipes by welding. The assembly requires a welding process, the assembly efficiency is low, the product quality is reduced, and the production cost is increased. Contents of the invention [0003] The object of the present invention is to provide a novel overflow pipe for solar water heaters which is free of welding, easy to install, firm in structure and improves product quality. [0004] In order to solve the problems existing in the background technology, the present invention adopts the following technical solutions: a novel overflow pipe for solar water heaters, including water inlet and outlet pipes and inst...
