Description
Technical field
The present invention relates to heat exchange equipment field, more particularly to a kind of heat exchanger venting device.
Background technology
Heat exchanger work in, hear sometimes heat exchanger rear portion suddenly " bang " a sound, that is due to steam or gas
Know from experience as temperature increases rapid expansion, pressure rapidly increases, and substantially exceeds the limiting pressure of container, due to heat exchanger rear portion
It is sealing, caused by gas cannot be discharged quickly.
In conclusion a kind of heat exchanger venting device to solve the above problems of invention is necessary.
Invention content
The present invention is directed to deficiencies of the prior art, provide it is a kind of it is simple in structure, can solve inside heat exchanger
The excessive heat exchanger venting device of pressure is necessary.
The purpose of the present invention is be achieved through the following technical solutions：
A kind of heat exchanger venting device, include mounted on heat exchanger rear portion fixed plate and be movably arranged on above fixed plate
Cover board, the fixed plate bottom is fixedly welded on heat exchanger rear portion, and fixed plate is provided centrally with air hole, the cover board covering
The air hole.
It advanced optimizes, if the fixed plate surrounding is uniformly provided with bolt stem, described bolt one end is welded on fixed plate bottom
Portion, the bolt other end sequentially pass through fixed plate, cover board and are arranged with cylindrically coiled spring, and the cylindrically coiled spring passes through nut
It is fixed.
It advanced optimizes, the bolt quantity is 6.
It advanced optimizes, the air hole is circle.
It advanced optimizes, the cover board is circle.
Invention advantageous effect：The heat exchanger venting device that the utility model provides, after fixed plate is mounted on heat exchanger
Portion, fixed plate center are equipped with air hole, and cover board covers air hole, and it is hidden which can exclude the larger safety of heat exchanger internal pressure
Suffer from, can effectively extend the service life of heat exchanger, also have the characteristics that it is of simple structure and low cost, be easily changed, convenient for popularization
It uses.

Specific implementation mode
It is noted that following detailed description is all illustrative, it is intended to provide further instruction to the application.Unless another
It indicates, all technical and scientific terms used herein has usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.Below according to drawings and examples, invention is further described in detail：
As shown in Figs. 1-2, a kind of heat exchanger venting device that the present invention records, includes the fixed plate mounted on heat exchanger rear portion
1 and it is movably arranged on the cover board 2 of the top of fixed plate 1,1 bottom of the fixed plate is fixedly welded on heat exchanger rear portion, fixed plate 1
It is provided centrally with air hole 3, the cover board 2 covers the air hole 3.
Preferably, if 1 surrounding of the fixed plate is uniformly provided with bolt stem 4,4 one end of the bolt is welded on 1 bottom of fixed plate
Portion, 1 other end of bolt sequentially pass through fixed plate 1, cover board 2 and are arranged with cylindrically coiled spring 5, and the cylindrically coiled spring 5 is logical
Cross the fixation of nut 6.
Preferably, 4 quantity of the bolt is 6.
Preferably, the air hole 3 is circle.
Preferably, the cover board 2 is circle.
Operation principle：For the utility model by the way that 1 bottom of fixed plate is fixedly welded on heat exchanger rear portion, fixed plate 1 is centrally disposed
There are air hole 3, cover board 2 to cover air hole 3, when the pressure of heat exchanger internal gas or steam is excessive, gas or steam pressure
Pressure is applied to cover board 2 by air hole 3, cover board 2 pops up and squeeze cylindrically coiled spring 5 outward under pressure, exchanges heat
Gas quickly excludes in device；After heat exchanger pressure reduction, cover board 2 under 5 reaction force of cylindrically coiled spring fix again by covering
3 heat exchanging of air hole on plate 1, which is thought highly of, to be newly sealed.
