Abstract

The utility model relates to a seal ring structure for a copper pipe of a water heater. The seal ring structure comprises an annular ring body; a through hole is formed in the ring body; a first limit groove is formed in the periphery of the through hole of the ring body; a second limit groove is formed in the inner wall of the through hole; the ring body is divided into a first seal section and a second seal section by the first limit groove; the peripheral seal face of the first seal section and the peripheral seal face of the second seal section are both oblique planes. According to the seal ring structure disclosed by the utility model, the water seepage phenomenon avoids being generated in the copper pipe of the water heater.

Description

Seal ring structure of water heater copper pipe

technical field

The utility model relates to an accessory of a solar water heater water tank, in particular to a sealing ring of a copper pipe of a solar water heater.

Background technique

The water inlet and outlet pipes of the existing solar water heaters are made of copper pipes. The copper pipes have good corrosion and heat resistance. The copper pipes need to be sealed at the pipe joints so that the copper pipes will not leak. The sealing rings are designed in a cylindrical shape, and this structure often causes water seepage.

Contents of the invention

The purpose of the utility model is to provide a sealing ring for the copper pipe of the solar water heater to avoid water seepage in the copper pipe of the solar water heater.

In order to achieve the above purpose, the technical solution of this utility model is: a sealing ring structure of a water heater copper pipe, including an annular ring body, a through hole is provided on the ring body, and a first limit position is provided on the outer periphery of the through hole of the ring body Groove, the inner wall of the through hole is provided with a second limiting groove, the first limiting groove divides the ring body into a first sealing section and a second sealing section, and the outer peripheral sealing surfaces of the first sealing section and the second sealing section All slopes.

The positive effect of the utility model is: since the outer periphery of the through hole of the ring body is provided with a first limiting groove, and the inner wall of the through hole is provided with a second limiting groove, the outer periphery of the copper pipe is processed during installation. Out of the limit protrusion, the inner wall of the pipe joint is processed into a limit protrusion, the first limit groove is clamped on the limit protrusion of the pipe joint, and the second limit groove is clamped on the copper pipe On the limit protrusion, it can be well limited and sealed, and because the first limit groove divides the ring body into the first sealing section and the second sealing section, the outer surface of the first sealing section and the second sealing section The surrounding sealing surface is inclined, and the sealing surface can be better deformed, so the sealing effect is further improved and water seepage is avoided.

Description of drawings

Fig. 1 is a structural sectional view of a specific embodiment of the present invention.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and the given embodiments, but it is not limited thereto.

As shown in Figure 1, a sealing ring structure of a water heater copper pipe includes an annular ring body 1, a through hole 1-1 is provided on the ring body 1, and a first The limit groove 1-2, the inner wall of the through hole 1-1 is provided with the second limit groove 1-3, the first limit groove 1-2 divides the ring body 1 into the first sealing section 1-4 and The outer peripheral sealing surfaces 1-6 of the second sealing section 1-5, the first sealing section 1-4 and the second sealing section 1-5 are all inclined surfaces.

The brief description of the use of the utility model is: when in use, the outer circumference of the copper pipe is processed into a limit protrusion, the inner wall of the pipe joint is processed into a limit protrusion, and the first limit groove 1-2 is clamped on the tube. On the limit protrusion of the joint, the second limit groove 1-3 is clamped on the limit protrusion of the copper pipe, so that the position and seal can be well limited, and because the first limit groove 1-3 2. Divide the ring body into the first sealing section 1-4 and the second sealing section 1-5. The outer peripheral sealing surfaces 1-6 of the first sealing section 1-4 and the second sealing section 1-5 are inclined surfaces, and the sealing surfaces 1-6 can be better deformed, so the sealing effect is further improved to avoid water seepage.
