Abstract
The utility model belongs to mechanical field, especially relates to a kind of hole structure of heat exchanger tube sheet, and for several pores are located on heat exchanger tube sheet, the long straight flange of the rectangle near outside is same straight flange with falling the bottom of isosceles trapezoid; The long straight flange of the rectangle near inner side is same straight flange with falling the upper base of isosceles trapezoid; The bottom interior angle of isosceles trapezoid is 45° angle.The utility model is transformed on traditional Tube Sheet of Heat Exchanger plate base, adds pore and to draw after ream with straight sided shape, match with sealing ring, when using heat exchanger pressing plate, be conducive to heat exchanger tube location and sealing, improve the quality of producing heat exchanger, improve work effect.
Description
Technical field
The utility model belongs to heat exchanger mechanical field, especially relates to a kind of hole structure of heat exchanger tube sheet.
Background technology
At present, in heat exchanger in the past, particularly in shell and tube double-tube heat exchanger, more owing to being arranged on tubulation quantity in pore, when using the sealing of traditional O RunddichtringO, be not easy location, and often easy by sealing ring flattening, cause leakage.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of easily location, and uses the hole structure being not easy the heat exchanger tube sheet flattened during sealing ring.
The utility model solves the technical scheme that its technical problem adopts, a kind of hole structure of heat exchanger tube sheet, for several pores are located on heat exchanger tube sheet, it is characterized in that, the cross section of hole structure is by being followed successively by rectangle, isosceles trapezoid and another rectangle inside lateral; The long straight flange of the rectangle near outside is same straight flange with falling the bottom of isosceles trapezoid; The long straight flange of the rectangle near inner side is same straight flange with falling the upper base of isosceles trapezoid; The bottom interior angle of isosceles trapezoid is 45° angle, near the setting of outside rectangular, matches with sealing ring, when using heat exchanger pressing plate, is conducive to heat exchanger tube location and sealing.
The beneficial effects of the utility model are, a kind of hole structure of heat exchanger tube sheet, the pore basis of traditional heat exchanger tube sheet is transformed, add pore to draw after ream with straight sided shape, matching with sealing ring, when using heat exchanger pressing plate, being conducive to heat exchanger tube location and sealing, improve the quality of producing heat exchanger, improve work effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the hole structure generalized section of tube sheet of the present utility model.
1. tube sheets in figure, 2. outer pore, 3. 45° angle, 4. straight flange.
detailed description of the invention
With reference to accompanying drawing, a kind of hole structure of heat exchanger tube sheet, for several pores are located on heat exchanger tube sheet 1, the cross section of the hole structure of this heat exchanger tube sheet is by being followed successively by rectangle, isosceles trapezoid and another rectangle inside lateral; Near rectangle and the outer mouth of pipe 2 of the formation of falling isosceles trapezoid in outside; The long straight flange 4 of the rectangle near outside is same straight flange with falling the bottom of isosceles trapezoid; The long straight flange 4 of the rectangle near inner side is same straight flange with falling the upper base of isosceles trapezoid; The bottom interior angle of isosceles trapezoid is 45° angle 3; Near the setting of the rectangle in outside, matching with sealing ring, when using heat exchanger pressing plate, being conducive to location and the sealing of heat exchanger tube.
