The above-mentioned structure adopted by the utility model has fewer parts and fewer sealing points, requires less precision in installation, and is easy to operate, which can reduce the labor intensity of workers; the sealing effect is relatively reliable, there is no possibility of leakage, and the service life can be improved.

Description

Coil installation sealing structure for solar water tank

technical field

The utility model relates to a sealing structure, in particular to a coil installation sealing structure for a solar water tank.

Background technique

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 that in the prior art, the thread seal and the clamp ring are often used to seal the copper coil (as shown in Figure 1). The disadvantage of this structure is: there are many parts; Many; thread processing requirements are high; workers' operations are cumbersome, unreliable, and labor-intensive; leakage may occur at the seal for a period of time after normal use.

Contents of the invention

The purpose of the utility model is to provide a coil installation and sealing structure for a solar water tank which has a simple structure and can ensure the sealing effect.

The problem to be solved by the utility model is achieved through the following technical scheme: it includes a water tank liner cylinder, a pipe seat and a nut, and the pipe seat is welded on the water tank liner cylinder, and it is characterized in that: the coil pipe and There is a sealing joint between the pipe seats, the sealing joint and the coil are welded together, a metal gasket is provided between the sealing joint and the butterfly contact surface of the pipe seat, a nut is set on the sealing joint, and the nut and the pipe seat are tightened by threads. Solid connection.

The structure adopted by the utility model has fewer parts and less sealing points, requires less precision in installation, and is easy to operate, which can reduce the labor intensity of workers; the sealing effect is relatively reliable, there is no possibility of leakage, and the service life can be improved.

Detailed ways

As can be seen from the accompanying drawings, the coil installation and sealing structure for a solar water tank includes a water tank inner tank body 1, a pipe base 2 and a nut 3, the pipe base 2 is welded on the water tank inner tank body 1, and the coil 4 is connected to the water tank inner tank body 1. There is a sealing joint 5 between the tube bases 2, and the sealing joint 5 is welded with the coil tube 4. The coil tube is made of copper tube material and can be welded by silver soldering. A metal gasket 6 is provided between the butterfly contact surfaces of the seat 2, and a nut 3 is set on the sealing joint 5, and the nut 3 and the pipe seat 2 are fastened and connected by threads. The metal gasket between the sealing joint and the pipe seat can be made of a thin copper sheet, and the metal extrusion is used to ensure that the sealing gasket, the pipe seat and the sealing joint are tightly combined without any gaps, and the surface seal is not leaked. The sealing function of the gasket under pressure is realized by filling the microscopic unevenness of the butterfly sealing surface after the sealing material yields.

Claims (1)
