Abstract
The utility model relates to a sealing ring with a wave-shaped inner wall, which is suitable to a full glass vacuum tube solar water heater (water boiler) and a hot-water supply system in an open type or a close type within a certain pressure range. The utility model is technically characterized in that the inner wall of the sealing ring forms a wave shape. The utility model has the advantages of good sealing performance, difficult damage and long service life.
Description
The utility model relates to the seal ring that a kind of inwall is a waveform, is applicable to whole glass vacuum tube solar energy heat (opening) hydrophone and the hot water supply system of closed loop in open or the certain pressure scope.
Seal ring is that whole glass vacuum tube solar energy heat (opening) hydrophone and the hot-water supply system of one of important sealed member of whole glass vacuum tube solar energy heat (opening) hydrophone and hot-water supply system, especially pressure-bearing type proposed requirements at the higher level to sealing configuration.Those skilled in the art are always with sealing configuration one of important topic as research for this reason.Chinese patent 94218450.5 discloses a kind of T RunddichtringO at present, its inwall has half inwardly outstanding more than 2 " 0 " shape ring, as as shown in Figure 1,1-1 is a T shape seal ring, and 1-2 is half " 0 " shape ring (" a kind of novel seal rubber ring " Instructions Page 2 the 1st～13 row).The advantage of this seal ring is a good seal performance, is convenient to install.By accompanying drawing 1 as seen, half " 0 " shape is encircled and partly is connected for cylinder between " 0 " shape ring, half " 0 " shape ring damages easily with the cylinder joint in use, especially when full-glass vacuum collector tube inserts water tank (or connecting pipe), when squeezing action was turned up seal ring top half " 0 " shape hoop, the seal ring root is very easy to break.
Goal of the invention of the present utility model is the deficiency at prior art, proposes a kind of seal ring of new structure, cooperates with the garden hole flanging of water tank (or connecting pipe), improves sealability, improves seal ring working life.
Technological points of the present utility model is that the inwall of T shape seal ring is a waveform.
Below in conjunction with accompanying drawing the utility model is described in detail, accompanying drawing 2 is sealing configuration longitudinal cross-section schematic representation that the utility model is formed, 2-1 is a T shape seal ring, 2-2 is the waveform inwall, 2-3 is water tank (or connecting tube), 2-4 is the garden hole flanging of water tank (or connecting pipe), and 2-5 is a glass vacuum solar collector tubes, and A is the direction that glass vacuum solar collector tubes inserts water tank (or connecting pipe).The waveform inwall has increased buffering stress as seen from the figure, form good sealing structure with the circle hole flanging and the glass vacuum solar collector tubes of water tank (or connecting pipe), and seal ring is not fragile.The waveform of T shape sealing density ring inwall has a halftime at least, and two or two above cycle sealing effects are better.
The utility model has the advantages that good seal performance and not fragile, long service life.
Description of drawings:
Accompanying drawing 1 is a T shape seal ring longitudinal cross-section schematic representation.
Accompanying drawing 2 is the utility model longitudinal cross-section schematic representation.
Accompanying drawing 3 is the utility model embodiment longitudinal cross-section schematic representation.
Embodiment
Accompanying drawing 3 has provided an embodiment of the present utility model, adopts rubber to make a T shape rubber ring, and the waveform of its inwall has 2 halftimes, outer diameter D
1Size is exceeding D with the sealing of water tank (or connecting pipe) garden hole flanging
2Size is exceeding D with the outer garden of the glass vacuum solar collector tubes opening end seal of tube
3Very little to the greatest extent greater than garden hole flanging diameter, h
1Height smaller or equal to the degree of depth of garden hole flanging flange, h
2Smaller or equal to 1/2h
1
Claims (3)
1, a kind of T shape seal ring is characterized in that inwall is a waveform.
2, according to the said T shape of claim 1 seal ring, it is characterized in that said inwall waveform, have a halftime at least, is best more than two or two.
3, according to claim 1 and 2 said T shape seal rings, it is characterized in that h
1Height preferably smaller or equal to the degree of depth of garden hole flanging flange.
