Description
Technical field
The utility model relates to a kind of high-pressure rubber-film sealing gas cabinet piston.
Background technique
Rubber diaphragm sealed gas holder is also referred to as door curtain made of cloth sealing gas holder, is that American Wei Jinsi is invention in 1940, so sometimes also claim Wei Shi (Wigging ' s) gas holder.It mainly is comprised of shell and the inner piston that moves up and down of steel, is rubber pattern cylindraceous between piston and the shell, in order to confining gas.
The piston of at present domestic rubber diaphragm sealed gas holder, its main structure is comprised of three parts, i.e. piston divider, concrete ring beam and spherical shell.The piston divider is along the circumference radially direct, and its underpart is a concrete ring beam, and the inside of ring beam is single flat slab spherical shell.The piston of this form has following shortcoming:
One, because spherical shell is the dull and stereotyped shell that is formed by polylith sheet metal overlap joint, it can only bearing tension, can rise when gas holder is inflated, and when not having gas, just can only directly be attached on the gas holder base plate.Ring beam also is directly to be attached on the base plate.Therefore the piston of this form need to arrange a large amount of temporary supportings at ring beam and spherical shell.At first on the piston spherical shell, with ring beam a plurality of flange holes are set, use at ordinary times the flange hole of flat flange shutoff on piston.When personnel will go to overhaul below piston, to first piston be risen certain height with normal air, below piston, have in the situation of air pressure, unload one by one flat flange, change one by one again the special flange at one section steel pipe of flat board weldering, tighten flange after, steel pipe then stretches to the below of piston, this special flange is called temporary supporting, just can hold piston by a large amount of temporary supporting steel pipes, makes and forms the needs that installation and maintenance are satisfied in one section space between piston and the piston base plate.There are many deficiencys in the rubber diaphragm sealed gas cabinet piston of this structure in use: 1, so branched support needs repeatedly to dismantle in use, and is to keep under the condition of gas storage at gas holder, so this process quite wastes time and energy.2, many temporary supportings will be opened a lot of circular holes at piston plate, add upper flange, and the point that produces gas leakage is a lot.This is for installation and check and maintenance in the future all increases a lot of difficulties and adverse effect factor.To high-pressure tank, piston weight is 3 ~ 4 times of normal pressure gas holders, and contradiction can be more outstanding.3, when dismounting temporary supporting piston fell, rubber membrane can produce very large pulling force, for high pressure cabinet, and the increase that its pulling force can be at double, rubber membrane is drawn bad possibility very big.
Two, the common dust loading of coal gas that stores of rubber membrane gas holder all very large (this also is its strong point).Therefore dust stratification is more after moving a period of time, when needing maintenance, emptying coal gas, and piston lands, and then uses the air hoisting piston, lays temporary supporting.At this moment, if dust stratification is many, some moisture again, piston and base plate will be sticked together, and again just rise to be difficult to.
Three, at present the structural type of piston divider all is triangular truss structure, and when increased pressure that piston stores, the lateral pressure that acts on the divider increases greatly, and this form just has been not suitable for.
Four, at present the gas holder Equilibrator wire rope suspension centre that connects counterweight all is arranged in the concrete ring beam, built concrete after, the position of suspension centre just fixing in the dust.The adjustable surplus of wire rope of the outer counterweight of connecting cabinet is just very little.In addition, suspension centre is below piston, and the center of gravity of whole like this piston just above suspension centre, has reduced counterbalance effect.
The model utility content
The purpose of this utility model provides a kind of high-pressure rubber-film sealing gas cabinet piston, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of high-pressure rubber-film sealing gas cabinet piston, comprise the piston divider, the top of described piston divider is provided with the ringwalk platform, this ringwalk platform is provided with some Equilibrator wire rope suspension centres, the bottom of piston divider is connected with reinforced concrete circle beam, the bottom of reinforced concrete circle beam is provided with the gas holder base plate, be separated with bearing beam between gas holder base plate and the reinforced concrete circle beam, the middle part of described reinforced concrete circle beam is provided with the self-supporting spherical shell, leaves space for maintenance between self-supporting spherical shell and the gas holder base plate; The top of described self-supporting spherical shell is divided into the reinforced concrete shell, and the bottom of self-supporting spherical shell is divided into the steel ball shell of putting more energy into; The structure of described piston divider is the door-shaped frame structure.
The beneficial effects of the utility model are:
1, because temporary supporting need not be set, therefore many troubles of installation, maintenance have been avoided, and reduced the factors that is unfavorable for safe operation, also avoided simultaneously rubber membrane to occur being drawn bad phenomenon to occur, guaranteed the Security of rubber membrane under high pressure conditions, the working life of having improved rubber membrane.
2, owing to need not to carry out perforate, steel pipe is installed, thereby the overall precision and the Security that have improved gas holder occur in the phenomenon of having avoided leaking air.
3, owing to be what separate between reinforced concrete circle beam and the gas holder base plate, therefore can be after gas holder move a period of time since dust stratification when piston is fallen and the gas holder base plate stick together, shine into overhaul difficult.
4, the more traditional English truss formula piston divider of the piston divider of portal frame formula more is adapted to high-pressure tank, when increased pressure that piston stores, acts on lateral pressure on the divider and can not follow it and significantly increase.
5, be arranged on the ringwalk platform at piston divider top owing to the wire rope suspension centre, thereby so that the center of gravity of whole piston below suspension centre, has improved counterbalance effect greatly, also be convenient to location and installation simultaneously.
