Abstract
The utility model belongs to mechanical field, especially relates to a kind of hole structure of heat exchanger pressing plate, pressing plate has several pores, and ream angle at 45 ° is with respect to the horizontal plane drawn in pore outside, closely cooperates with sealing ring; The beneficial effects of the utility model are, the pore basis of traditional heat exchanger pressing plate is transformed, add pore and draw ream angular shape at 45 °, closely cooperate with sealing ring, when using heat exchanger pressing plate, be conducive to heat exchanger tube location and sealing, improve the quality that heat exchanger is produced, improve operating efficiency.
Description
Technical field
The utility model belongs to mechanical field, especially relates to a kind of hole structure of heat exchanger pressing plate.
Background technology
At present, in shell and tube double-tube heat exchanger, because heat exchanger tube quantity is more, heat exchanger tube is also more by the pore of heat exchanger pressing plate, and sealing ring is arranged in pore, when using the sealing of O RunddichtringO, often easy by sealing ring flattening, causes heat exchanger leakage.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of hole structure of heat exchanger pressing plate, and when using sealing ring, sealing ring is not easy to be crushed, and heat exchanger not easily causes leakage.
The utility model solves the technical scheme that its technical problem adopts, a kind of hole structure of heat exchanger pressing plate, pressing plate there are several pores, it is characterized in that, the exit orifice of the pore on pressing plate is greater than endoporus, and ream angle at 45 ° is with respect to the horizontal plane drawn in pore outside, closely cooperates in pore with sealing ring, when using heat exchanger pressing plate, be conducive to the sealing of heat exchanger tube location and sealing ring.
The beneficial effects of the utility model are, a kind of hole structure of heat exchanger pressing plate, the basis of traditional heat exchanger pressing plate pore is transformed, add the shape that ream angle at 45 ° is with respect to the horizontal plane drawn in pore outside, closely cooperating with sealing ring in pore, when using heat exchanger pressing plate, being conducive to the sealing of heat exchanger tube location and sealing ring, improve the quality of producing heat exchanger, improve operating efficiency.
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 the utility model pressing plate.
1. pressing plates, 2. pore, 3. 45° angle in figure.
Detailed description of the invention
With reference to accompanying drawing, a kind of hole structure of heat exchanger pressing plate, pressing plate there are several pores 2, the exit orifice of the pore 2 on pressing plate 1 is greater than endoporus, ream angle 3 at 45 ° is with respect to the horizontal plane drawn in pore 2 outside, closely cooperating with sealing ring in pore 2, when using heat exchanger pressing plate, being conducive to the sealing of heat exchanger tube location and sealing ring.
