Abstract
The utility model provides a sealing ring for a collecting pipe of a solar thermal collector. The sealing ring is characterized in that the middle part of a sealing ring body is provided with a groove; the groove is fitted with a to-be-sealed cavity wall; one end of the groove is provided with a large gripping ring; the other end of the groove is provided with a small gripping ring; outer ring inner end faces of the large gripping ring and the small gripping ring are respectively provided with annular tooth-shaped bulges. When the collecting pipe is inserted, the outer surface of the collecting pipe is tightly packaged by the annular tooth-shaped bulges arranged on the inner ring faces to achieve a very good sealing effect; the two gripping ring faces are both designed to be oblique planes attached to the face of the cavity wall, and are respectively provided with the annular tooth-shaped bulges, and further, the very good sealing effect is achieved. The sealing ring for the collecting pipe of the solar thermal collector, provided by the utility model, has the advantages that the structure is simple, and the operation is convenient; the impurity prevention effect of the complete machine is improved, so that a drier and cleaner working environment can be kept in a cavity, the performance of the thermal collector is more stable, and the service life of the thermal collector is effectively prolonged.
Description
Technical field
The utility model relates to a kind of sealing ring, is specifically related to a kind of solar thermal collector collector sealing ring.
Background technology
The collector of flat-plate solar collector, when stretching out heat collector and go along with sb. to guard him cavity wall, for the intrusion of waterproof and dust, is provided with a rubber seal, but because of structural reason, does not mostly reach expected effect.Thereby in use through this passage still have dust particularly outside moisture infiltrate in cavity as rainwater or damp vapour etc., thereby strengthened the moisture in heat collector cavity.These moisture can be evaporated out when heat collector air drying or hot operation, when temperature reduces, can be condensed again and stick to table and absorber surface formation water smoke and steam in cap rock, can cause following adverse consequences: heat-insulating material thermal conductivity factor rises, heat waste increases; Cap rock transmitance declines, and the sun is injected energy and reduced: absorbed layer makes moist, and makes the rotten degeneration of coating; On dissimilar metal tube plate absorber, can produce electrochemical corrosion.These can cause thermal performance of collectors to decline and the lost of life.
Utility model content
The purpose of this utility model is for problems of the prior art, and a kind of solar thermal collector collector sealing ring is provided.
A kind of solar thermal collector collector sealing ring of the present utility model, comprises sealing ring body, and is provided with groove at the middle part of sealing ring body, one end of this groove is large holding ring, and the other end is little holding ring; On the outer shroud inner face of large holding ring and little holding ring, be equipped with ring-type toothed projections.
Described groove is suitable with the cavity wall sealing.
In order better to play sealing effectiveness, in described sealing ring body, be equipped with ring-type toothed projections.
The inner face that described large clamping anchor ring and clip are held anchor ring outer shroud is inclined-plane.
The relative prior art of the utility model has the following advantages:
1, solar thermal collector collector sealing ring of the present utility model, when inserting collector, the ring-type toothed projections that inner ring surface is provided with tightly wraps up the outer surface of collector, reaches good sealing effectiveness.
2, solar thermal collector collector sealing ring of the present utility model, two clamping anchor rings are all made as the inclined-plane that is affixed to cavity wall, and are equipped with ring-type toothed projections, further reach good sealing effectiveness.
3, solar thermal collector collector sealing ring of the present utility model, simple in structure, easy to operate, improved the anti-assorted effect of complete machine, make can keep drier, a cleaner working environment in cavity, make thermal performance of collectors more stable, effectively extended the service life of heat collector.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A portion enlarged drawing of the utility model inner ring surface.
Fig. 3 is the B portion enlarged drawing of the utility model size clamping anchor ring.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Solar thermal collector collector sealing ring as shown in Figure 1, Figure 2, Figure 3 shows, comprises sealing ring body, and the middle part of sealing circle body is provided with groove 8, and this groove 8 is suitable with the cavity wall 1 that will seal.One end of groove 8 is large holding ring 6, and the other end is little holding ring 7; On the outer shroud inner face of large holding ring 6 and little holding ring 7, be equipped with ring-type toothed projections 5.
The outer shroud inner face of large holding ring 6 and little holding ring 7 is inclined-plane, and is equipped with ring-type toothed projections 5; In sealing ring body 2, be equipped with ring-type toothed projections 4.
Ring-type toothed projections 4 on the cylinder inner ring surface of rubber seal body 2, after collector 3 inserts, collector 3 outer round surface that wrap that are crushed out of shape tightly because of its ring-type toothed projections play sealing function; Its large clamping anchor ring 6 is individual to the inclined-plane 6 of going along with sb. to guard him the surface tilt of cavity wall 1, is also provided with ring-type toothed projections 5 on Gai inclined-plane simultaneously, produces distortion, thereby make the anchor ring 6 of this inclination be pressed on corresponding wall and play sealing function when being affixed to this wall; The outer rim that corresponding clip is held anchor ring 7 also has ring-type toothed projections 5, and also because its distortion is pressed on wall, these sealing surface actings in conjunction form a complete hermetically-sealed construction.
