Sealing method for mounting coil pipe of solar water tank

Abstract

The invention discloses a sealing method for mounting a coil pipe of a solar water tank, which comprises the following steps: extending a copper coil pipe (4) out of a mounting hole position of a water tank liner cylinder body (1), sheathing a sealing joint (5) with a butterfly sealing surface at the pipe end of the copper coil pipe (4), and welding the sheathed parts of the sealing joint (5) and the copper coil pipe (4) by adopting a silver-soldering brazing process; sheathing a sealing gasket (6) machined by a thin copper sheet on the butterfly sealing surface of the sealing joint (5), and inserting the welded sealing joint (5) into an inner hole of a pipe seat (2) for mounting in place; and sheathing a nut (3) on the sealing joint (5), and connecting and fastening the nut (3) and the screw thread on the pipe seat (2). The method of the invention has the advantages of low mounting requirement precision and simple operation, can reduce the labor intensity of workers, has relatively reliable sealing effect, and can prolong the service life.

Description

technical field [0001] The invention relates to a sealing method, in particular to a sealing method used for installing solar water tank coil pipes. 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 sealing method are: more parts; more sealing points; high thread processing requirements; cumbersome, unreliable, and labor-inten...

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 sealing method 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.
