The present invention relates to field of heat exchangers, specifically related to a kind of plate type heat exchanger fishbolt, including shank of bolt, it is welded in the fixing nut of shank of bolt one end and the binding nut being sheathed on shank of bolt, the graduation mark for identification length is evenly arranged with shank of bolt, pin hole is offered between 2 graduation marks, binding nut is tightened onto after corresponding graduation mark to be arranged in pin hole by pin and fixed, and pin is used for spacing binding nut；The setting of graduation mark, the fishbolt on every shank of bolt is facilitated to be torqued-up to corresponding scale, so that every binding nut is located at the identical position on shank of bolt, it can thus make it that the stress of every fishbolt is identical, clamping force between clamped plate and plate is just as the phenomenon of leakage will be reduced accordingly.The mutual cooperation of pin and pin hole causes fishbolt to be not in that stripped thread phenomenon plays good position-limiting action, during dismounting, need to only pull out pin, then fishbolt is rather opened, installation, convenient disassembly.
Description
Technical field
The present invention relates to field of heat exchangers, and in particular to a kind of plate type heat exchanger fishbolt.
Background technology
Plate type heat exchanger is by a series of a kind of high-performance heat exchanger of sheet metal closed assemblies with certain bellows-shaped.
Thin rectangular shape passage is formed between various plates, heat exchange is carried out by plate.Plate type heat exchanger is liquid-liquid, liquid-vapour progress
The ideal equipment of heat exchange.It has heat exchange efficiency height, small heat loss, advantages of compact and light structure, floor space is small, be widely used,
The features such as service life is long.Under uniform pressure damaed cordition, its ratio of heat transfer coefficient pipe heat exchanger is high 3-5 times, floor space
For 1/3rd of pipe heat exchanger, heat recovery rate may be up to more than 90%.
Existing plate type heat exchanger includes fixed pressure plate, plate package, movable pressure plate etc., and above-mentioned is fixed and clamped
After plate, plate package, movable pressure plate are installed in order, pass through some folders that are uniform up and down and being arranged parallel to
Tight bolt is clamped fixation.The binding nut combination fixing nut of existing fishbolt will pass through lock after above-mentioned each board clamping
Determine padlock and determine binding nut, with the time lengthening used, tab and binding nut will occur to glue between fishbolt
Phenomenon even, difficulty is caused to emotionally disassembly, cleaning, and because fishbolt is be evenly arranged up and down some, every
Fishbolt is without related reference being fixedly clamped, it is possible to which the clamping force for every fishbolt occur is different, is caused each
The discontinuity of root fishbolt.
The content of the invention
The problem of existing for prior art, solves existing fishbolt and steps up to fix not corresponding during each plate
Normative reference the problem of cause the discontinuity of each fishbolt, the invention provides a kind of clamping of plate type heat exchanger
Bolt.
Concrete technical scheme is as follows：
A kind of plate type heat exchanger fishbolt, including shank of bolt, be welded in the fixing nut of described shank of bolt one end with
And it is sheathed on the graduation mark being evenly arranged with the binding nut on the shank of bolt, the shank of bolt for identification length, 2
Pin hole is offered between the graduation mark, binding nut is tightened onto after corresponding graduation mark is arranged in the pin hole by pin
Middle fixation, the pin is used for spacing binding nut；
It is preferred that, the rear end of the fixing nut is fixed with pad；
It is preferred that, the rear end of the pad is fixed with guide sleeve；
It is preferred that, the radius of the pin is less than the radius of the shank of bolt；
It is preferred that, the pin hole is opened in the postmedian of the shank of bolt；
It is preferred that, the pin and the pin hole are set perpendicular to the shank of bolt.
Beneficial effect：
The setting of graduation mark on shank of bolt, facilitates the fishbolt on every shank of bolt to be torqued-up to corresponding scale, makes
The identical position that every binding nut is located on the shank of bolt is obtained, can thus cause the stress phase of every fishbolt
Together, the clamping force between clamped plate and plate is just as the phenomenon of leakage will be reduced accordingly.The phase interworking of pin and pin hole
Close and make it that fishbolt is not in that stripped thread phenomenon plays good position-limiting action, during dismounting, pin need to only be pulled out, then will folder
Tight bolt is rather opened, installation, convenient disassembly.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1：The cross-sectional view of the present invention.
Reference is as follows：
1st, shank of bolt, 2, fixing nut, 3, pad, 4, guide sleeve, 5, graduation mark, 6, pin hole, 7, pin, 8, clamp spiral shell
It is female.
Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in the embodiment of the present invention
Technical scheme is clearly and completely described, it is clear that described embodiment is a part of embodiment of the invention, rather than entirely
The embodiment in portion.Based on the embodiment in the present invention, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of protection of the invention.
Referring to Fig. 1：A kind of plate type heat exchanger fishbolt, including shank of bolt 1, it is welded in described one end of shank of bolt 1
Fixing nut 2 and the binding nut 8 being sheathed on the shank of bolt 1.
The graduation mark 5 for identification length is evenly arranged with the shank of bolt 1.
The hole 6 of pin 7 is offered between 2 graduation marks 5.
Binding nut 8, which is tightened onto after corresponding graduation mark 5, is arranged in the hole 6 of pin 7 fixed, the pin by pin 7
Nail 7 is used for spacing binding nut 8.
The rear end of the fixing nut 2 is fixed with pad 3；The rear end of the pad 3 is fixed with guide sleeve 4；
The radius of the pin 7 is less than the radius of the shank of bolt 1；The hole 6 of pin 7 is opened in the shank of bolt 1
Postmedian；The hole 6 of pin 7 and the pin 7 is set perpendicular to the shank of bolt 1.
During installations, the grip dimensions needed for fishbolt are determined according to the size of clamped part, are determined after size,
Binding nut 8 is set on shank of bolt 1, and pretty be torqued-up at required size of binding nut 8 is stopped, at this moment by pin
7, which penetrate the fixed i.e. completion in the hole 6 of first pin 7 of the rear end of binding nut 8, installs.
The setting of graduation mark 5 on shank of bolt 1, facilitates the fishbolt on every shank of bolt 1 to be torqued-up to corresponding scale,
So that every binding nut 8 is located at the identical position on the shank of bolt 1, it can thus cause the stress of every fishbolt
Identical, the clamping force between clamped plate and plate is just as the phenomenon of leakage will be reduced accordingly.Pin 7 and the hole 6 of pin 7
Cooperate and make it that fishbolt is not in that stripped thread phenomenon plays good position-limiting action, during dismounting, pin 7 need to only be pulled out
Fall, then fishbolt is rather opened, installation, convenient disassembly.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
The present invention is described in detail, it will be understood by those within the art that：It still can be to foregoing each implementation
Technical scheme described in example is modified, or carries out equivalent substitution to which part technical characteristic；And these modification or
Replace, the essence of appropriate technical solution is departed from the spirit and scope of various embodiments of the present invention technical scheme.
