Abstract
The utility model discloses a sealing sleeve for a wall-through thermal insulation pipe. The sealing sleeve is fixed on the outer side of the thermal insulation pipe which is required to pass through a wall; the outer side of the sealing sleeve is a concrete wall; the sealing sleeve is made of rubber and can play a role of flexible connection, thus the sealing effect between the thermal insulation pipe and the wall is guaranteed; and meanwhile, the internal surface and the external surface of the sealing sleeve are threaded surfaces, so that the contact surface between the sealing sleeve and the thermal insulation pipe and the contact surface between the sealing sleeve and the wall are rough, the contact area of each rough contact surface is larger than that of a smooth surface, and the stability of flexible connection is guaranteed. Besides, the sealing sleeve also has the advantage that as the outer diameter of a sealing sleeve body is gradually increased from one end to the other end, the lateral load borne by the thermal insulation pipe is offset. The sealing sleeve can be applied to the engineering in which the groundwater level is higher than the burial depth and can serve as pipe fittings to guarantee the water tightness of the wall when a pipeline passes through the wall.
Description
Technical field
The utility model relates to the stuffing box gland of a kind of thermal insulation pipe usefulness through walls.
Background technique
Central heat supply is the public utilities that public character is very strong, and winter heating is the basal needs of the northern area of China people's lives.In the winter of severe cold, see sometimes to occur " steaming " phenomenon on the road.After entering freeze-up, the pressure and temperature of a secondary net of central heat supply progressively raises, and in the cell of some poor sealing, behind the Groundwater infiltration, the e-quipment and pipe that runs into little Indoor Thermal has just become steam, thereby situation about " steaming " above the road occurred.This situation very easily causes the generation of traffic accident for the traffic trip of pedestrian and vehicle has brought great inconvenience because of the sight line that affects pedestrian or driver.
The model utility content
The utility model has been designed and developed the stuffing box gland of a kind of thermal insulation pipe usefulness through walls.In model utility, at the outside of needs thermal insulation pipe through walls fixing seal cover, the outside of stuffing box gland is concrete wall, and stuffing box gland is quality of rubber materials, can play the effect that flexibly connects, thereby guarantee the sealing effect between thermal insulation pipe and the body of wall, simultaneously, the inner and outer surface on stuffing box gland surface is flank of thread so that and the surface of contact between thermal insulation pipe and the body of wall all more coarse, and have the area of contact larger than smooth surface, guarantee the stability that flexibly connects.The utility model has reduced the generation of " steaming " phenomenon, has ensured the water tightness of body of wall, and the equipment in the cell, valve etc. are played effective protection.
The technological scheme that the utility model provides is:
The stuffing box gland of a kind of thermal insulation pipe usefulness through walls comprises:
Body, it is the hollow structure of inner cylindrical shape, and the internal surface of described body and outer surface all have flank of thread, and described body is quality of rubber materials.
Preferably, in the stuffing box gland of described thermal insulation pipe usefulness through walls, described internal surface is flank of thread; Described outer surface is flank of thread.
Preferably, in the stuffing box gland of described thermal insulation pipe usefulness through walls, described body has the structure that its external diameter is increased to the other end gradually by an end.
Preferably, in the stuffing box gland of described thermal insulation pipe usefulness through walls, the length of described body is 50mm.
Preferably, in the stuffing box gland of described thermal insulation pipe usefulness through walls, described body is 22mm at the thickness of the large end of external diameter.
The stuffing box gland of thermal insulation pipe described in the utility model usefulness through walls, at the outside of needs thermal insulation pipe through walls fixing seal cover, the outside of stuffing box gland is concrete wall, stuffing box gland is quality of rubber materials, can play the effect that flexibly connects, thereby guarantee the sealing effect between thermal insulation pipe and the body of wall, simultaneously, the inner and outer surface on stuffing box gland surface is flank of thread, so that and the surface of contact between thermal insulation pipe and the body of wall all more coarse, and have the area of contact larger than smooth surface, guarantee the stability that flexibly connects.In addition, the utility model also has another beneficial effect, and namely the external diameter of stuffing box gland body is the structure that is increased gradually to the other end by an end, and this structure is conducive to offset the suffered lateral load of thermal insulation pipe.The utility model has reduced the generation of " steaming " phenomenon, has ensured the water tightness of body of wall, and the equipment in the cell, valve etc. are played effective protection.
The utility model can be applicable to level of ground water and is higher than in the engineering of buried depth, guarantees the pipe fittings of the water tightness of body of wall when can be used as the Pipeline Crossing Program body of wall.
Description of drawings
Fig. 1 is the structural representation of the stuffing box gland of thermal insulation pipe described in the utility model usefulness through walls.
Fig. 2 is the mounting structure figure of the stuffing box gland of thermal insulation pipe described in the utility model usefulness through walls.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
As shown in Figure 1, the utility model provides the stuffing box gland of a kind of thermal insulation pipe usefulness through walls, comprising: body 1, and it is the hollow structure of inner cylindrical shape, and internal surface 12 and the outer surface 11 of described body all have flank of thread, and described body 1 is quality of rubber materials.
In the stuffing box gland of described thermal insulation pipe usefulness through walls, described internal surface is flank of thread; Described outer surface is flank of thread.
In the stuffing box gland of described thermal insulation pipe usefulness through walls, described body has the structure that its external diameter is increased to the other end gradually by an end.
In the stuffing box gland of described thermal insulation pipe usefulness through walls, the length of described body is 50mm.
In the stuffing box gland of described thermal insulation pipe usefulness through walls, described body is 22mm at the thickness of the large end of external diameter.
Stuffing box gland of the present utility model at first passes thermal insulation pipe 3 inside of stuffing box gland body 1 in installation process, use concrete to fix in the outside of body 1.
Be subjected to lateral load at thermal insulation pipe 3, and body of wall 4 thickness can use a plurality of stuffing box glands during greater than 250mm, to guarantee sealing effect.As shown in Figure 2, the arranged outside of thermal insulation pipe has two stuffing box glands, and the exposed part of the thermal insulation pipe between two stuffing box gland bodies is wrapped with adhesive tape 2.At this moment, the end that the external diameter of stuffing box gland body is larger is positioned at body of wall inside, the edge of the close body of wall of an end that external diameter is less.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the mode of execution, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
