Abstract

The utility model relates to a rubber sealing ring. A groove is arranged on the outer and lateral wall of the rubber sealing ring. The inner and lateral wall of the rubber sealing ring is a conical surface. A port part of the big circle of the conical surface is a circular chamfering. The wall of the groove of the outer and lateral wall, which is near to the end of the big circle of the conical surface of the inner wall is a salient circle. The utility model enables a Solar heat-collecting pipe to be installed conveniently. Moreover, in the process of installation, the outer margin at the end part of the rubber sealing ring can not be coiled into a water tank.

Description

A kind of rubber seal

The utility model relates to a kind of rubber seal, is particularly useful for the water tank (or connecting pipe) of glass vacuum tube solar (opening) hydrophone and the sealing between the glass vacuum heat collection tube of solar energy.

At present, the sealing between glass vacuum heat collection tube of solar energy and the water tank (or connecting pipe) is finished by a cone seal rubber ring.The structure of cone rubber seal of tube circle as shown in Figure 1, the outer rim of cone rubber circle 1-1 has a circular groove 1-2, a V-shaped groove 1-3 is arranged at the top.The schematic cross-section of cone seal rubber ring as shown in Figure 2,2-1 is the cone rubber circle, 2-2 is an annular groove, 2-3 is a V-shaped groove.The cone seal rubber ring is installed on the circular hole of water tank (or connecting pipe), block the edge of water tank (or connecting pipe) circular hole by the groove of cone seal rubber ring, glass vacuum heat collection tube of solar energy inserts water tank (or connecting pipe) by the cone seal rubber ring, forms sealing configuration.Accompanying drawing 3 is sealing configuration schematic cross-sections, 3-1 is water tank (or connecting pipe), and 3-2 is the garden bore edges of water tank (or connecting pipe), and 3-3 is the cone seal rubber ring, 3-4 is a glass vacuum heat collection tube of solar energy, and A is the direction that glass vacuum heat collection tube of solar energy inserts water tank (or connecting pipe).By finding out in the accompanying drawing 3, glass vacuum heat collection tube of solar energy can only insert along the centerline direction of rubber seal, and solar energy heat collection pipe is because of the restriction of the water heater structure that is heated, often can not insert along the seal ring centerline direction, then heat collecting pipe is difficult to insert smoothly in the rubber ring, even insert, also usually rubber seal is clamp-oned in the water tank, bring very burden to installation.

The purpose of this utility model is at above-mentioned defective, designs a kind of new type rubber seal ring, and the sealing circle can guarantee that solar energy heat collection pipe can not insert in the seal ring smoothly along the seal ring centerline direction yet.

The purpose of this utility model is realized by following technical proposals:

Change the madial wall of present rubber seal into the conical surface, conical surface great circle port part is a rounded corner.The wall near the big nose circle of the madial wall conical surface of outer side wall groove is a dome.

Technical characterstic of the present utility model is: easy for installation, and can not damage rubber seal, and can will not get in the water tank in the solar energy heat collection pipe installation process as glue seal ring end outer rim turnup.

Below in conjunction with accompanying drawing the utility model is done further narration:

Accompanying drawing 1 is existing ring structure schematic representation.

1-1 is that conical seal ring, 1-2 are that annular groove, 1-3 are V-shaped grooves among the figure.

Accompanying drawing 2 is schematic cross-sections of existing seal ring.

2-1 is a seal ring among the figure, and 2-2 is an annular groove, and 2-3 is a V-shaped groove.

Accompanying drawing 3 is sealed structural representations of existing seal ring.

3-1 is a water tank among the figure, and 3-2 is the garden bore edges of water tank, and 3-3 is a seal ring, and 3-4 is a solar energy heat collection pipe, and A is the direction that heat collecting pipe inserts water tank.

Accompanying drawing 4 is schematic cross-sections of the present utility model.

4-1 is an annular groove among the figure, and 4-2 is an inner conical surface, and 4-3 is a rounded corner, and 4-4 is a dome.

As shown in Figure 4, the utility model ring outer side wall is groove 4-1, and the inboard is conical surface 4-2, and conical surface great circle port part is rounded corner 4-3, and the wall near the big nose circle of conical surface of inboard wall of outer side wall groove 4-1 is dome 4-4.Because whole inwall is conical surface 4-2, conical surface oral area has rounded corner 4-3 in addition, so, solar energy heat collection pipe does not need to insert along the seal ring centerline direction like that as shown in Figure 3 when inserting seal ring, made things convenient for installation, and in dome 4-4 guarantees that rubber seal can the insertion turnup inlet water tank because of solar energy heat collection pipe.

Claims

1, a kind of rubber seal, the ring outer side wall has groove one, it is characterized in that madial wall is a conical surface.

2, a kind of rubber seal of narrating according to claim 1 is characterized in that conical surface great circle port part is a rounded corner.

3, a kind of rubber seal of narrating according to claim 1 is characterized in that along the wall near the big nose circle of conical surface of inboard wall of outer side wall groove be dome.
