Coil pipe mounting and sealing structure for solar water tank

Abstract

The invention discloses a coil pipe mounting and sealing structure for a solar water tank. The coil structure comprises a water tank liner cylinder body (1), a pipe seat (2) and a nut (3), wherein the pipe seat (2) is welded to the water tank liner cylinder body (1); a sealing joint (5) is arranged between a coil pipe (4) and the pipe seat (2); the sealing joint (5) is welded with the coil pipe (4) together; a metal sealing gasket (6) is arranged between the butterfly contact faces of the sealing joint (5) and the pipe seat (2); the nut (3) is sleeved on the sealing joint (5); and the nut (3) and the pipe seat (2) are fastened and connected through screw threads. By adopting the structure, because of few parts, the sealing point is few, the mounting requirement precision is low, the operation is simple, and the labor intensity of workers can be reduced; and the sealing effect is comparatively reliable, the possibility of leakage does not exist, and the service life can be prolonged.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a coil installation sealing structure for a solar water tank. Background technique [0002] At present, the use of solar energy is becoming more and more popular, and the development of solar water heating systems is also increasing day by day. In the solar hot water system, the solar water tank is an important part of water storage. In addition to electric heating in the water tank, coils are often used to use medium circulation as water heat exchange, thereby improving the heat exchange effect of the water tank. There will be problems in production. The technical problem of installing and sealing the solar water tank coil is usually sealed by thread sealing and snap ring squeezing the copper coil in the prior art (such as figure 1 ), the disadvantages of this structure are: more parts; more sealing points; high thread processing requirements; cumbersome, unreliable, and labor-intensive o...

Problems solved by technology

In the solar hot water system, the solar water tank is an important part of water storage. In addition to electric heating in the water tank, coils are often used to use medium circulation as water heat exchange, thereby improving the heat exchange effect of the water tank. There will be problems in production. The technical problem of installing and sealing the solar water tank coil is usually sealed by thread sealing and snap ring squeezing the copper coil in the prior art (such as figure 1 ), the disadvantages of this structure are: more parts; more sealing points; high thread processing requirements; cumbersome, unreliable, and labor-intensive operations for workers; leakage may occur at the seal for a period of time after normal use, etc.
