Description
Technical field
This utility model is related to a kind of high pressure equipment of the supporting storing energy of Hydraulic Power Transmission System, more particularly, to a kind of high pressure
Spherical tank.
Background technology
High-pressure ball type gas tank is the high pressure equipment for the supporting storing energy of Hydraulic Power Transmission System.This equipment design pressure
33mpa, 50 DEG C of design temperature, operation medium is air, spherical tank interior diameter 1200mm, housing wall thickness 70mm.Material of main part is
13mnnimor high-strength panel and 20mnmo forging.
As shown in figure 1, why high-pressure ball type gas tank makes upper and lower two hemispherical head butt welding structures, it is because spherical
End socket stress is best, thus required housing wall is thin, equipment lower overall weight.Manhole is arranged on top, manhole connecting pipe make with spherical
End socket docks pattern.This structural advantages are that stressing conditions are preferable, and shortcoming is that the forging's block dimension of manhole connecting pipe is big, and adapter bottom adds
Work becomes sphere, manufactures complicated processing amount big.And blind flange is hydraulicefficiency tightening formula with the connecting bolt of flange, it is a set of special to need
Instrument tightening.
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 ball type gas tank.
The purpose of this utility model is achieved through the following technical solutions:
High-pressure ball type gas tank of the present utility model, including to upper half dome head welded together and lower half dome head,
The top of described upper half dome head is provided with manhole, and the inner side of described manhole is provided with lower cover, and the outside of described manhole is provided with
Gland, described lower cover is connected through the hinge in the inwall of described upper half dome head, logical between described upper press cover and lower cover
Cross bolt connection.
The high-pressure ball type of this utility model embodiment offer is provided by the technical scheme that above-mentioned this utility model provides
Gas tank, is changed to hinge type self-fastening sealing structure due to being tightly connected manhole device from flange form pressure type, alleviates equipment
Gross weight, conveniently open, improve sealing.

Specific embodiment
This utility model embodiment will be described in further detail below.
High-pressure ball type gas tank of the present utility model, preferably specific embodiment is as shown in Figures 2 to 5 for it:
Including to upper half dome head welded together and lower half dome head, the top of described upper half dome head is 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, and described lower cover is connected through the hinge
In the inwall of described upper half dome head, it is 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 half
The inwall of dome 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 ball type gas tank of the present utility model, manhole device is tightly connected from flange form pressure type and is changed to hinge type certainly
Compact form sealing structure, such change stress is good as original, is calculated with stress analysis through us, and maximum stress controls
In tolerance zone.Structure great advantage after improvement is to eliminate manhole connecting pipe and this two larger forging of blind flange, mitigates
Equipment gross weight.Avoid the high-leveled and difficult manufacture processing that curved surface is processed in adapter bottom, connecting bolt is from the hydraulic pressure of 16 m70x3
Compact form bolt is changed to only be tightened with two m48x3 screw bolts, and self-energized seal performance be better than original mandatory close
Envelope.
Compared with prior art, 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.
In sum, after this utility model scheme determines, through multi-party scheme evaluating, obtained the accreditation of brainstrust, existing
Complete in high-pressure ball type gas tank detail of design, and also devised within this several years the equipment that multiple stage is similar to, some products successively
Operation has been put into.Facts have proved that this improvement is feasible, have the bright prospects that development is carried out.
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.
