Abstract
Stainless steel manhole is served as a contrast the utility model discloses a kind of rotary cap, include a connecting tube, mutually welded with a slip-on welding flange one end of connecting tube, it is provided with a manhole cover with matching with the slip-on welding flange, manhole cover is provided with multiple fixing threaded holes, fixing threaded hole is centrosymmetric distribution centered on the center of circle of manhole cover, is provided with one first hand hole, one second hand hole and one the 3rd hand hole on manhole cover, and the first hand hole, the second hand hole and the 3rd hand hole are connected independently of one another and with connecting tube.Rotary cap lining stainless steel manhole of the present utility model is mainly made up of flanged (FLGD) connecting tube and manhole cover, three hand holes independent of each other are provided with the manhole cover, it can so be used in the case where manhole cover is covered as hand hole, also there is the function of manhole, so as to allow manhole to be united two into one with hand hole, the function that the rotary cap serves as a contrast stainless steel manhole has been expanded significantly.
Description
Technical field
The utility model is related to a kind of manhole, more precisely, being a kind of rotary cap lining stainless steel manhole.
Background technology
Manhole is mounted in safety in tank roof and met an urgent need air-breather, generally with flame damper, mechanical breather valve is supporting makes
With being both avoided that because of drastically superpressure or during vacuum in tank caused by accidental cause, and damaged storage tank and occur accident, safety is played again
Back-fire relief is acted on, and is the safety device for protecting storage tank, is particularly suitable for use in storing the vault normal pressure tank that material is bound with nitrogen.With fixed
Pressure is put, level pressure is sucked, be opened and closed flexible, safe back-fire relief, compact conformation, good seal performance, it is safe and reliable the advantages of.It is universal at present
The manhole used typically only has the function of manhole, and function is more single.
Utility model content
The utility model is mainly the technical problem solved present in prior art, so that providing one kind has manhole and hand concurrently
The rotary cap lining stainless steel manhole of hole function.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
A kind of rotary cap serves as a contrast stainless steel manhole, and comprising a connecting tube, one end of connecting tube is mutually welded with a slip-on welding flange, with
The slip-on welding flange is provided with a manhole cover with matching, and manhole cover is provided with multiple fixing threaded holes, and fixing threaded hole is with manhole cover
Be centrosymmetric distribution centered on the center of circle, and one first hand hole, one second hand hole and one the 3rd hand hole, first are provided with manhole cover
Hand hole, the second hand hole and the 3rd hand hole are independent of one another and are connected with connecting tube.
As the utility model preferred embodiment, the hand hole cover of described the first hand hole, the second hand hole and the 3rd hand hole
It is made up of safety glass.
As the utility model preferred embodiment, described connecting tube and slip-on welding flange is integrally formed.
Rotary cap lining stainless steel manhole of the present utility model is mainly made up of flanged (FLGD) connecting tube and manhole cover, the manhole
Cover and be provided with three hand holes independent of each other, can so be used in the case where manhole cover is covered as hand hole, it may have
The function of manhole, so as to allow manhole to be united two into one with hand hole, has expanded the function that the rotary cap serves as a contrast stainless steel manhole significantly.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the dimensional structure diagram that rotary cap of the present utility model serves as a contrast stainless steel manhole.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
As shown in figure 1, a kind of rotary cap lining stainless steel manhole 1, comprising a connecting tube 10, one end of connecting tube 10 and one flat
Welding method orchid 11 is mutually welded, and is provided with a manhole cover 20 with matching with the slip-on welding flange 11, and manhole cover 20 is provided with multiple fixations
Screw 21, fixing threaded hole 21 is centrosymmetric distribution centered on the center of circle of manhole cover 20, and one first is provided with manhole cover 20
Hand hole 31, one second hand hole 32 and one the 3rd hand hole 33, the first hand hole 31, the second hand hole 32 and the 3rd hand hole 33 independently of one another and
It is connected with connecting tube 10.
Further improved as to the utility model, described the first hand hole 31, the second hand hole 32 and the 3rd hand hole
33 hand hole cover is made up of safety glass.
Further improved as to the utility model, described connecting tube 10 and slip-on welding flange 11 is integrally formed.
The rotary cap lining stainless steel manhole of the utility model is mainly made up of flanged (FLGD) connecting tube and manhole cover, the manhole
Cover and be provided with three hand holes independent of each other, can so be used in the case where manhole cover is covered as hand hole, it may have
The function of manhole, so as to allow manhole to be united two into one with hand hole, has expanded the function that the rotary cap serves as a contrast stainless steel manhole significantly.
Only illustrate mentality of designing of the present utility model in one embodiment above, in the case where system allows,
The utility model can expand to external more functional modules simultaneously, so as to extend its function to greatest extent.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
