Abstract
The utility model relates to a kind of Sealing encapsulated for stoneware pipe and end plate, belongs to tube connection piece field.For the Sealing that stoneware pipe and end plate encapsulate, it is characterized in that, described Sealing is the truncated cone shape of hollow, is provided with a circle ring-shaped winged at the stub end of Sealing.The utility model is applicable to the encapsulation of stoneware pipe and end plate, overlaps inner sleeve outward in the seal, and after applying an axial force to inner sleeve, the seal can seal the radial and axial of stoneware pipe simultaneously, and good airproof performance.
Description
Technical field
The utility model relates to a kind of Sealing, particularly a kind of Sealing encapsulated for stoneware pipe and end plate.
Background technique
Pottery has high thermal conductivity, corrosion resistance, high temperature resistant and excellent mechanical property, has major application in field of heat exchange.The traditional heat exchangers such as heat exchanger opposing metallic, graphite adopting ceramic exchanging tube to prepare can bear harsher environment.
In actual use, the connection of ceramic tubing and encapsulation are key technologies.Harsh operating mode not only heat exchanging material has very high requirement, also requires that the encapsulation of tubing can ensure resistance to high temperature and the withstand voltage properties of complete equipment simultaneously.Good encapsulation performance is directly connected to the working life of complete equipment.
The tubing of prior art is tightly connected, and as Chinese patent 200720051128.6, is only applicable to plastic tube, lining moulds Stainless Steel Tube etc., and cannot meet and enbrittle and unmanageable ceramic tubing.
Model utility content
The purpose of this utility model is for the problems referred to above, and provide a kind of Sealing encapsulated for stoneware pipe and end plate, the seal can seal the radial and axial of stoneware pipe simultaneously.
The purpose of this utility model is achieved in that
For the Sealing that stoneware pipe and end plate encapsulate, it is characterized in that, described Sealing is the truncated cone shape of hollow, is provided with a circle ring-shaped winged at the stub end of Sealing.
Wherein, the outer inclined-plane of the axial cross section of described Sealing is 75-88 degree with radial angle.
Wherein, the material of described Sealing is rubber or plastics.
The beneficial effects of the utility model are: the utility model is applicable to the encapsulation of stoneware pipe and end plate, inner sleeve is overlapped outward in the seal, after applying an axial force to inner sleeve, the seal can seal the radial and axial of stoneware pipe simultaneously, and good airproof performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is enforcement illustration of the present utility model.
Embodiment
Below in conjunction with specific embodiments and the drawings, set forth the utility model further.
As shown in Figure 1, a kind of Sealing encapsulated for stoneware pipe and end plate, the profile of the seal 3 is circular cone shape, the outer inclined-plane of its axial cross section is 75-88 degree with radial angle, the center of Sealing 3 has the through through hole 31 of an axis, is provided with a circle ring-shaped winged 32 at the stub end of Sealing 3.The material of the seal 3 can be rubber or plastics.
As shown in Figure 2, by the encapsulation of this Sealing 3 specifically for stoneware pipe and end plate, its encapsulation process is as follows, stoneware pipe 4 is inserted in the macropore of shoulder hole from the small bore end of end plate 5 shoulder hole, overlap Sealing 3 successively in the insertion end of ceramic 4 pipes and there is the inner sleeve 2 of the madial wall matched with the outer side wall of Sealing 3, finally external fiber tube 1 is screwed into the large nose end of end plate 5 shoulder hole, herein, the macropore inwall of shoulder hole and external fiber tube 1 has the internal and external threads matched, external fiber tube 1 is advanced to apply an axial force to inner sleeve 2 by rotating, profile due to Sealing 3 is circular cone shape, and its stub end is provided with a circle ring-shaped winged 32, inner sleeve 2 can make Sealing 3 be fitted on the outside tube wall of stoneware pipe 4 more closely on the one hand, play the effect of radial seal, on the other hand, the ring-shaped winged 32 of Sealing 3 is pressed on the ladder surface of end plate 5 shoulder hole by one end face of inner sleeve 2, play the effect of axial seal.
Claims (2)
1. the Sealing encapsulated for stoneware pipe and end plate, it is characterized in that, the profile of described Sealing (3) is circular cone shape, the center of Sealing (3) has the through through hole (31) of an axis, is provided with a circle ring-shaped winged (32) at the stub end of Sealing (3);
The outer inclined-plane of the axial cross section of described Sealing (3) is 75-88 degree with radial angle.
2. a kind of Sealing encapsulated for stoneware pipe and end plate according to claim 1, is characterized in that, the material of described Sealing (3) is rubber or plastics.
