Description

Silicone sealing plug for solar vacuum heat collecting tube

technical field

The utility model relates to a silica gel sealing plug of a solar vacuum heat collecting tube.

Background technique

Existing solar vacuum heat collecting tubes, when forming solar heat collectors or solar water heaters, also use silica gel sealing rings or silica gel sealing plugs, but no matter with silica gel sealing rings or silica gel sealing plugs, there is only one opening of the vacuum tube nozzle. The forced water circulation in the vacuum tube cannot be realized, and the water in the vacuum tube can only undergo microcirculation, and it is easy to deposit dirt.

Utility model content

The technical problem to be solved by the utility model is to overcome the above-mentioned deficiencies in the prior art, and to provide a silica gel sealing plug for solar vacuum heat collecting tubes with reasonable structural design, which has low cost and can realize the forced circulation of water in the vacuum tube, effectively Improve the heat collection efficiency of solar vacuum heat collection tubes and prevent fouling.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a solar vacuum heat collecting tube silica gel sealing plug, including a plug body, characterized in that: there are two passages penetrating through the plug body in the axial direction of the plug body hole.

The two through holes described in the utility model are arranged in parallel.

The two through holes described in the utility model both deviate from the central axis of the plug body.

The radii of the two through holes described in the utility model are the same.

The plug body described in the utility model is composed of a sealing body and a cover body, the sealing body and the cover body are integrally formed, and a sealing ring is arranged on the outer peripheral wall of the sealing body.

Compared with the prior art, the utility model has the following advantages and effects: two through holes are used to install two metal inlet and outlet pipes, so that each solar vacuum heat collecting tube can be installed with one long and one short metal inlet and outlet pipes, as follows Advantages: 1. It can realize the forced circulation in the solar vacuum heat collecting tube and improve the heat collection efficiency of the solar vacuum heat collecting tube; 2. It can absorb the hot water in the solar vacuum heat collecting tube through the metal tube inside the tube and use it to increase the utilization of hot water; 3. , Avoid the accumulation of dirt in the solar vacuum heat collecting tube.

Detailed ways

Below in conjunction with accompanying drawing and through embodiment the utility model is further described.

Referring to Fig. 1 to Fig. 4, the embodiment of the utility model includes a plug body 1 made of silica gel. The plug body 1 is composed of a sealing body 2 and a cover body 3. A sealing ring 4 is provided on the peripheral wall of the outer wall, and the sealing ring 4 makes the sealing effect of the sealing body 2 on the solar vacuum heat collecting tube 6 better, and the cover body 3 is convenient for the installation of the plug body 1. The radius of the cover body 3 is larger than that of the sealing body 2, which is more convenient for the installation of the plug body 1.

In the axial direction of the plug body 1, there are two through holes 5 through the plug body 1, which are used to install two metal water inlet and outlet pipes, so that each solar vacuum heat collecting tube 6 can be installed with one long and one short metal water inlet and outlet pipes, It has the following advantages: 1. The forced circulation in the solar vacuum heat collecting tube 6 can be realized, and the heat collection efficiency of the solar vacuum heat collecting tube 6 can be improved; 2. The hot water in the solar vacuum heat collecting tube 6 can be sucked out by the metal tube inside the tube, and the heat can be increased. 3. Avoid the accumulation of dirt in the solar vacuum heat collecting tube 6 .

The two through holes 5 are arranged in parallel, and the two through holes 5 deviate from the central axis of the plug body 1, so that it is more convenient to install two metal water inlet and outlet pipes. The radii of the two through holes 5 are the same, which is convenient for processing.

First, the first metal water pipe 7 and the second metal water pipe 8 are installed on the plug body 1, and then the sealing plug equipped with the first metal water pipe 7 and the second metal water pipe 8 is inserted into the opening of the solar vacuum heat collector tube 6 to form A heat collecting tube with water inlet and outlet pipes, two or more of the heat collecting tubes are connected with water pipes to form a solar heat collector with any number of tubes.
