Anti-rust pipe seat structure and water heater adopting structure

Abstract

The invention relates to an anti-rust pipe seat structure and a water heater adopting the structure, and belongs to the technical field of the water heater. The anti-rust pipe seat structure comprises an anti-rust material lining pipe (5) embedded and fixed at an open hole part of a tube body plate (6), wherein a pipe seat (2) provided with connecting internal screw threads at the outer end tightly sleeves the outside of the lining pipe (5), a sheath (1) made of anti-rust materials sleeves the outside of the pipe seat (2), the inner end of the sheath (1) is provided with an external flange, an anti-rust material guide pipe (4) is inserted and arranged in the lining pipe (5), the outer end opening of the guide pipe (4) is provided with an outwards expanded flange, an elastic threaded sealing sleeve (3) with the C-shaped cross section is clamped and arranged on the outwards expanded flange, and the outer circle of the threaded sealing sleeve (3) is provided with a bulge embedded into an internal threaded groove. The anti-rust pipe seat structure and the water heater have the advantages that the inner and outer structures are simultaneously, reasonably and effectively improved, so that the problem of rust water outward leakage can be effectively solved.

Description

technical field [0001] The invention relates to a rust-proof pipe seat structure, and also relates to a water heater adopting the structure, belonging to the technical field of water heaters. Background technique [0002] The water tank of the water heater is provided with cast iron material pipe sockets forming various pipeline interfaces such as water inlet and outlet. For a long time, the corrosion of the pipe seat of the water heater has always been a problem that cannot be effectively solved. Because the rust of the pipe seat can occur inside and outside, the internal corrosion is caused by the flow of water in the pipe seat, and the outer wall is rusted because the external rainwater, water vapor, etc. will contact it. What is particularly nerve-wracking is that regardless of internal corrosion or external wall corrosion, it is inevitable to leave rust spots on the surface of the water tank where rust water seeps out. [0003] In order to prevent the outer wall of th...

Problems solved by technology

However, neither the lining nor the enamel layer can extend to the threaded section at the outer end of the inner hole of the pipe seat, so it cannot form an effective comprehensive covering protection, and still cannot prevent the inner rust of the pipe seat and the outflow of rusty water

[0005] In addition, in the prior art mentioned above, when replacing the outer connecting pipe with a shorter thread length, the end face of the outer connecting pipe will not be able to fit the outer end face of the inner liner, so even the original basic sealing state is not difficult to maintain, and it is easier for rusty water to flow out Phenomenon
