Abstract
The utility model provides a kind of tower equipment skirt cylindrical shell reducing costs, reduce manufacture difficulty, increase service life, comprise cylindrical shell, be positioned at equally distributed multiple release groove on the periphery of cylindrical shell top, described release groove is made up of with the dilatation joint being communicated with two release aperture the release aperture at two ends.Tower equipment skirt cylindrical shell of the present utility model, on skirt cylindrical shell top, circumferentially longitudinally the method for the stress relief grooves of uniform respective numbers avoids the destruction of the equipment caused because of heat fatigue.This structure effectively can discharge the additional stress because the equipment skirt cylindrical shell top that cold cycling causes frequently produces, avoid the tearing tendency of weld seam between skirt and housing caused because of heat fatigue, and the service life that can reduce costs, reduce manufacture difficulty, increase equipment.
Description
Technical field
The utility model relates to a kind of tower equipment, especially a kind of tower equipment skirt cylindrical shell.
Background technology
Tower equipment is bearing low temperature repeatedly to high temperature, when high temperature is to the operating process of low temperature, along with rising or the reduction of operating temperature, apparatus casing will produce expansion or shrinkage phenomenon, the skirt overlapped with tower housing will inevitably cause skirt cylindrical shell top to produce additional stress by the impact of this phenomenon, this additional stress may cause the destructions such as weld cracking, in order to alleviate this stress, in conventional design, general consideration increase apparatus casing or skirt cylindrical shell wall thickness, skirt and tower body attachment weld carry out the methods such as special process and carry out relieve stresses fatigue rupture.The methods such as increase thickness will inevitably make manufacturing cost increase, energy consumption increases and can increase manufacture difficulty, do not meet the policy that national energy-saving reduces discharging.
Utility model content
The utility model provides a kind of tower equipment skirt cylindrical shell reducing costs, reduce manufacture difficulty, increase service life.
Realize the tower equipment skirt cylindrical shell of the utility model object, comprise cylindrical shell, be positioned at equally distributed multiple release groove on the periphery of cylindrical shell top, described release groove is made up of with the dilatation joint being communicated with two release aperture the release aperture at two ends.
The diameter of described release aperture is 13mm.
The width of described dilatation joint is 5mm.
The distance of center circle of two described release aperture is 220mm.
The center of circle of the release aperture above described release groove and the distance at cylindrical shell top are 30mm.
The beneficial effect of tower equipment skirt cylindrical shell of the present utility model is as follows:
Tower equipment skirt cylindrical shell of the present utility model, on skirt cylindrical shell top, circumferentially longitudinally the method for the stress relief grooves of uniform respective numbers avoids the destruction of the equipment caused because of heat fatigue.This structure effectively can discharge the additional stress because the equipment skirt cylindrical shell top that cold cycling causes frequently produces, avoid the tearing tendency of weld seam between skirt and housing caused because of heat fatigue, and the service life that can reduce costs, reduce manufacture difficulty, increase equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of tower equipment skirt cylindrical shell of the present utility model.
Detailed description of the invention
As shown in Figure 1, tower equipment skirt cylindrical shell of the present utility model, comprises cylindrical shell 1, is positioned at equally distributed multiple release groove on the periphery of cylindrical shell 1 top, and described release groove is made up of with the dilatation joint 3 being communicated with two release aperture 2 release aperture 2 at two ends.
The diameter of described release aperture 2 is 13mm.
The width of described dilatation joint 3 is 5mm.
The distance of center circle of two described release aperture 2 is 220mm.
The center of circle of the release aperture 2 above described release groove and the distance at cylindrical shell 1 top are 30mm.
Tower equipment skirt cylindrical shell of the present utility model, on skirt cylindrical shell top, circumferentially longitudinally the method for the stress relief grooves of uniform respective numbers avoids the destruction of the equipment caused because of heat fatigue.This structure effectively can discharge the additional stress because the equipment skirt cylindrical shell top that cold cycling causes frequently produces, avoid the tearing tendency of weld seam between skirt and housing caused because of heat fatigue, and the service life that can reduce costs, reduce manufacture difficulty, increase equipment.
Embodiment recited above is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the utility model designs spiritual prerequisite; the various distortion that the common engineers and technicians in this area make technical solutions of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
