Description
Technical field
The present invention relates to shell-and-tube heat exchanger field, specifically a kind of multi-tube pass heat exchanger hydroecium prevents the hand hole cover of interior leakage
Plate.
Background technology
It, generally will be in hydroecium for the needs of plant maintenance using the shell-and-tube heat exchanger of flat head (hydroecium cover board)
1 is opened on cover board or several hand holes are used to detect the state inside hydroecium.When heat exchanger is multitube distance, in order to avoid trepanning is made
Into the interior leakage between tube side, it is necessary to hand hole be avoided to be arranged at pass partition.Since the difference of hand hole position has also derived not
With model so that the hydroecium canopy-type number of same specification (i.e. diameter is identical) is numerous, interchangeability is poor, is caused to manufacturing management
Additional burden.In addition, excessive trepanning can reduce the intensity of hydroecium cover board, for smaller hydroecium cover board, since space has
Limit can also cause the difficulty that hand hole is arranged.
Invention content
The purpose of the present invention is overcoming the shortcomings of in above-mentioned background technology, a kind of multi-tube pass heat exchanger hydroecium is provided and prevents interior leakage
Hand hole cover board, which can avoid leaking in caused by open up hand hole, and hand hole is arranged at pass partition and is also not required to
Opponent hole site is wanted to be adjusted, may be used interchangeably the hydroecium cover board of same specification.
The present invention provides following technical schemes：
A kind of multi-tube pass heat exchanger hydroecium prevents the hand hole cover board of interior leakage, and the hand hole cover board includes being fixed by screws in water
Outer cover plate on room cover plate, it is characterised in that：The side of the outer cover plate towards hand hole has additional one section of extension pipe, the lengthening
End surfaces are fixedly connected with circular seal plate；The sum of the length of the extension pipe and the thickness of sealing plate and the thickness of hydroecium cover board
It is identical.
The outer diameter of the extension pipe is slightly less than the diameter of sealing plate；The diameter of the sealing plate is matched with hand hole internal diameter,
To ensure sealing effect.
The diameter of the outer cover plate is more than hand hole internal diameter.
The central axis of the upper cover plate, extension pipe and sealing plate is coaxial.
The beneficial effects of the invention are as follows：Sealing board diameter in the present invention is identical with the internal diameter of hand hole, and extension pipe
The sum of length and the thickness of sealing plate are identical with the thickness of hydroecium cover board, it is ensured that sealing plate end face and the inside of hydroecium cover board
Face is concordant, can be ignored the gap of interior leakage, prevents that interior leak occurs between hydroecium.In this way, water box cover can be largely reduced
Template number significantly improves the interchangeability of hydroecium cover board, so as to considerably reduce labor content, significantly improves work effect
Rate reduces production cost.In addition, the configuration of the present invention is simple, easy to operate, it is easy to utilize.
Description of the drawings
Fig. 1 is the structure diagram of hand hole cover board of the present invention.
Fig. 2 is the structure diagram that existing multi-tube pass heat exchanger hydroecium avoids interior leakage.
Fig. 3 is the structure diagram leaked in existing multi-tube pass heat exchanger hydroecium occurs.
Fig. 4 is that the present invention avoids the structure diagram leaked in hydroecium.
Specific embodiment
With reference to the accompanying drawings of the specification, the invention will be further described, but the invention is not limited in following embodiments.
As shown in the figure, a kind of multi-tube pass heat exchanger hydroecium prevents the hand hole cover board of interior leakage, including outer cover plate 1, outer cover plate it is straight
Diameter is more than hand hole internal diameter and is fixed by screws at the hand hole 6 of hydroecium cover board 4.Above structure is same as the prior art.
The present invention's thes improvement is that：The side of the outer cover plate towards hand hole has additional one section of extension pipe 2, described to add
The end face of long tube is fixedly connected with circular seal plate 3；The sum of the length of extension pipe and the thickness of sealing plate and the thickness of hydroecium cover board
Spend it is identical, with ensure install after sealing plate end face it is concordant with hydroecium cover board medial surface；So as to prevent that interior leakage occurs between hydroecium,
Ensure sealing effect.The outer diameter of extension pipe is slightly less than the diameter of sealing plate, (therefore diameter and the hand hole internal diameter of sealing plate match
There are certain intervals, such as Fig. 4 between extension pipe and hand hole inner wall), be conducive to the assembling of hand hole cover board；The upper cover plate, lengthening
The central axis of pipe and sealing plate is coaxial.
When hand hole is arranged in the position of pass partition 5, it is only necessary to determine sealing plate and extension pipe according to hand hole internal diameter
Diameter determines the thickness of sealing plate and the length of extension pipe according to the thickness of hydroecium cover board, so as to avoid hydroecium cover board is replaced
Inconvenience.It can be arranged at pass partition additionally, due to hand hole, can also accordingly reduce the quantity in hydroecium cover board left-hand seat hole, increased
Strong hydroecium cover board intensity.
Arrow A is hydroecium water (flow) direction in figure, and arrow B is interior leakage current direction.
Finally it should be noted that listed above is only specific embodiments of the present invention.It is clear that the invention is not restricted to
Above example can also have many variations.Those of ordinary skill in the art can directly lead from present disclosure
All deformations for going out or associating, are considered as protection scope of the present invention.
