Multiple series, design temperature is 50～70 DEG C, and operation medium is air or water, operates medium to be divided into water pot and gas tank two by it
The form of kind, has 4m3 and 2m3 two class by its volume.Material of main part is 13mnnimor high-strength panel and 20mnmo forging.
As shown in figure 1, the structure of high pressure accumulator is diameter dn1000mm cylindrical vertical revolving body, upper low head adopts
The best dome head of stress, stack shell adopts monolayer bending thick plates.Manhole is arranged on top, and manhole connecting pipe is made and spherical envelope
Head docking pattern.This structural advantages are provided in stressing conditions on dome head, and preferably, shortcoming is the forging chi of manhole connecting pipe
Very little big, sphere is processed in adapter bottom, manufactures complicated processing amount big.And blind flange is hydraulicefficiency tightening with the connecting bolt of flange
Formula, needs a set of special instrument to tighten.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, good airproof performance, open convenient high pressure accumulator manhole.
The purpose of this utility model is achieved through the following technical solutions:
High pressure accumulator manhole of the present utility model, including cylindrical vertical revolving body, described cylindrical vertical revolving body
Top be provided with upper cover, the top of described upper cover is provided with manhole, and the inner side of described manhole is provided with lower cover, described manhole

Specific embodiment
This utility model embodiment will be described in further detail below.
High pressure accumulator manhole of the present utility model, preferably specific embodiment is as shown in Figures 2 to 5 for it:
Including cylindrical vertical revolving body, the top of described cylindrical vertical revolving body is provided with upper cover, described upper cover
Top be provided with manhole, the inner side of described manhole is provided with lower cover, and the outside of described manhole is provided with upper press cover, described lower cover lead to
Cross the inwall being hingedly connected at described upper cover, be bolted between described upper press cover and lower cover.
Described hinge includes the connecting rods of two mutual handing-over, the other end of two connecting rods respectively with described lower cover and upper envelope
The inwall of head is hinged.
It is provided with sealing gasket between the lower edge of the top edge of described lower cover and described manhole.
High pressure accumulator manhole of the present utility model, manhole device is tightly connected from flange form pressure type and is changed to hinge type
Self-fastening sealing structure.
Specific embodiment:
As shown in Figures 2 to 5, manhole device's design improves, manhole device is sealed from flange form pressure type
Connect and be changed to hinge type self-fastening sealing structure.
Such change stress is the same good with original, is calculated with stress analysis through us, maximum stress controls allowable
In the range of.Structure great advantage after improvement is to eliminate manhole connecting pipe and this two larger forging of blind flange, alleviates and sets
Standby gross weight.Avoid the high-leveled and difficult manufacture processing that curved surface is processed in adapter bottom, connecting bolt is from the hydraulicefficiency tightening formula of 16 m70x3
Bolt is changed to only be tightened with two m48x3 screw bolts, and self-energized seal performance is better than original forced sealing.
Compared with former technology, the utility model has the advantage of:
From the point of view of technical elements:
Manhole Sealing Joints after improvement adopt metal plain cushion and nitrile rubber " o " type ring bilayer self-tightening type structure, have sealing
Performance is good, durable in use, and the features such as reliable, self-energized seal on high pressure equipment is better than forced sealing.
Manufacture difficulty of processing to reduce.Manhole connecting pipe originally is made and is docked pattern with dome head, and adapter bottom is processed into
Sphere, this needs the very high numerically controlled lathe of precision just to enable.Structure after improvement only needs to general lathe with two pieces of flat covers and adds
Work, and processing capacity very little.
Machine weight mitigates.Due to eliminating manhole connecting pipe and this two larger forging of blind flange, manhole connects spiral shell
Bolt is only changed to two m48x3 screw bolts from the hydraulicefficiency tightening formula bolt of 16 m70x3, so always weigh about alleviating 3 tons.
Because manhole employs hinge type quick-opening structure after improvement, more convenient for maintenance.
From the point of view of economic aspect:
Material-saving expense: eliminate manhole connecting pipe and this two larger forging of blind flange, and manhole connecting bolt
Only it is changed to two m48x3 screw bolts from the hydraulicefficiency tightening formula bolt of 16 m70x3, Master Cost can be saved 250,000 yuan
RMB.
Processing charges reduces: only consider remove adapter bottom be processed into space curved surface this so that it may save processing charges
With 100,000 yuans.
Save the specific purpose tool of a set of hydraulicefficiency tightening device: flange bolt is changed into tightening from original hydraulicefficiency tightening formula
Formula, has saved 120,000 yuan of hydraulicefficiency tightening device expense.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
It is confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is defined by the protection domain of claims.
