Abstract
The utility model discloses a channel cover for a heat exchanger. The channel cover for the heat exchanger comprises a channel cover board (1) and is characterized in that a laminated board (2) is arranged on the inner wall of the channel cover board (1), plug welding holes (3) is formed in the laminated board (2), and the laminated board (2) and the inner wall of the channel cover board (1) are connected in a welding mode through the plug welding holes (3). According to the channel cover for the heat exchanger, a bead welding layer is replaced by the laminated board arranged on the inner wall of the channel cover board and the channel cover board and the laminated board are fixed in a welding mode through the plug welding holes, so that the deformation of the channel cover after the bead welding layer is welded is avoided. Meanwhile, the welding time is shortened, the manufacturing cost is reduced, the production materials are saved, and the manufactured channel cover has the advantages of being resistant in corrosion, long in service life and suitable for popularization and use.
Description
Technical field
The utility model relates to technical field of chemical, relates in particular to the heat exchanger technical field, and specifically a kind of speed of production is fast, cost is low and the channel cover that is used for heat exchanger of economical with materials.
Background technology
In technical field of chemical, heat exchanger is common equipment, and often corrosivity is large owing to the medium in the heat exchanger, therefore requires the inwall of channel cover is processed, and adds resistant material.Channel cover structure chart of the prior art as shown in Figure 1, at the inwall of cover plate 1 multiple-bead deposit layer 4 is set and carries out corrosion-resistance treatment, present overlay cladding 4 generally is not less than 5 layers, gross thickness and is not less than 8mm, on technological requirement, requirement is carried out levelling to overlay cladding 4, unevenness is less than 2mm, and said process is high to operating personnel's requirement height, longevity of service and cost; The unevenness of the overlay cladding 4 of making in addition is still larger, and corrosion-resistant degree is low, so channel cover is short service life, needs often to change.
Summary of the invention
The purpose of this utility model is the problem that exists for existing channel cover, provides that a kind of speed of production is fast, cost is low and the channel cover that is used for heat exchanger of economical with materials.
The purpose of this utility model solves by the following technical programs:
A kind of channel cover for heat exchanger comprises cover plate, it is characterized in that the inwall of described cover plate is provided with thick china, and thick china is provided with plug welding hole, is weldingly connected by plug welding hole between the inwall of thick china and cover plate.
Described thick china adopts resistant material to make.
The thickness of described thick china is not less than 8mm.
Described plug welding hole is evenly distributed on the thick china.
The utility model has the following advantages compared to existing technology:
The utility model arranges thick china by the inwall at cover plate and replaces overlay cladding and adopt plug welding hole to be welded and fixed cover plate and thick china, the channel cover of having avoided causing after the overlay cladding welding is out of shape, shorten simultaneously weld interval, reduced manufacturing cost and saved the production material, characteristics corrosion-resistant, long service life that the channel cover of making has, suitable promoting the use of.
Description of drawings
Accompanying drawing 1 is channel cover structural representation of the prior art;
Accompanying drawing 2 is channel cover structural representation of the present utility model.
Wherein: 1-cover plate; 2-thick china; 3-plug welding hole; 4-overlay cladding.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 2: a kind of channel cover for heat exchanger, comprise cover plate 1, inwall at cover plate 1 is provided with the thick china 2 that adopts resistant material to make, the thickness of thick china 2 is not less than 8mm, be provided with equally distributed plug welding hole 3 at thick china 2, be weldingly connected by plug welding hole 3 between the inwall of thick china 2 and cover plate 1; In addition in welding process, at first strengthen stability between the inwall of thick china 2 and cover plate 1 with the transition zone plug welding, then improve compatibility between plug welding and the thick china 2 with the coating plug welding.
The utility model arranges thick china 2 by the inwall at cover plate 1 and replaces overlay cladding 4 and adopt plug welding hole 3 to be welded and fixed cover plate 1 and thick china 2, the channel cover of having avoided causing after overlay cladding 4 welding is out of shape, shorten simultaneously weld interval, reduced manufacturing cost and saved the production material, characteristics corrosion-resistant, long service life that the channel cover of making has, suitable promoting the use of.
Above embodiment only is explanation technological thought of the present utility model, can not limit protection domain of the present utility model with this, every technological thought according to the utility model proposes, any change of doing on the technical scheme basis all falls within the utility model protection domain; The technology that the utility model does not relate to all can be realized by prior art.
