Abstract
The utility model discloses a hydraulic expand tube fixture for a boiler tube. The hydraulic expand tube fixture comprises an inlet baffle plate, guide blocks, a boiler expand tube, heat radiating sheets and an outlet baffle plate, wherein the inlet baffle plate is fixedly connected with the inlet of the boiler expand tube, the outlet baffle plate is fixedly connected with the outlet of the boiler expand tube, the right side of the inlet baffle plate and the left side of the outlet baffle plate are connected with the guide blocks, the guide blocks are sleeved on the outer wall of the boiler expand tube, and a plurality of heat radiating sheets are sleeved on the outer wall of the boiler expand tube at equal intervals, and are square heat radiating sheets with circular holes in the middle. The hydraulic expand tube fixture is low in cost, electricity-saving in an assembly process and easy to maintain and increases the utilization rate because the boiler expand tube and the heat radiating sheets are tightly sealed.
Description
Technical field
The utility model relates to the hydraulic expanding tube technical field, is specifically related to boiler tube and uses the hydraulic expanding tube frock.
Background technology
Existing boiler tube is used the hydraulic expanding tube frock, and the fin that splices on its boiler expand tube outer wall is a H shape, and H shape fin needs to be welded on boiler expand tube outer wall through high-frequency welding machine, and operation easier is high, and assembling power consumption is high, and equipment cost is high.And maintaining also comparatively the trouble, the boiler expand tube of welding and the airtight performance of fin are not high yet.
The utility model content
The utility model purpose: the purpose of the utility model is in order to remedy the deficiency of prior art, to provide a kind of boiler tube of processing ease to use the hydraulic expanding tube frock.
The technical scheme that the utility model adopts: a kind of boiler tube is used the hydraulic expanding tube frock; Constitute by import baffle plate, guide pad, boiler expand tube, fin and outlet damper; Said import baffle plate is fixedly connected with boiler expand tube inlet; Said outlet damper is fixedly connected with the outlet of boiler expand tube, and said import baffle plate right side and outlet damper left side all are connected with guide pad, and said guide pad is socketed in boiler expand tube outer wall; Said boiler expand tube outer wall equidistance separately be socketed with several cooling fins, said fin is the middle square radiating plate that is provided with circular hole.
Said guide pad is connected with import baffle plate and outlet damper through symmetrically arranged nut.
The diameter of said circular hole and boiler expand tube external diameter are equal to.
Beneficial effect: the utility model equipment cost is low, and assembling process is power saving more, and maintaining is easy, and boiler expand tube and fin airtight performance are good, improves the equipment availability.
