Description

Oblasť technikyTechnical field

Vynález sa týka nádrže s pripojenou šachtou na prídavné zariadenia a jej ochrany proti korózii.The invention relates to a tank with an attached shaft for attachments and its protection against corrosion.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Nádržne na plyn, uložené v zemi sa odlišujú od voľne stojacich nádrží rôznym vybavením, ktoré má obzvlášť za cieľ ich ochranu proti korózii a umožnenie prístupu k rôznym zariadeniam, ktorými je nádrž vybavená a ktoré sú nutné na jej činnosť: napúšťací ventil, vypúšťací kohút pre plyn alebo kvapalinu, vodoznak, poistný ventil atd.Gas tanks stored in the ground are distinguished from freestanding tanks by different equipment, which is specifically designed to protect them against corrosion and to allow access to the various equipment with which the tank is equipped and which are necessary for its operation: inlet valve, drain cock for gas or liquid, watermark, safety valve, etc.

Ochrana týchto zariadení proti vlhkosti je veľmi dôležitá, lebo voda môže spôsobiť zhoršenie funkčnosti týchto zariadení a týra ohroziť používanie nádrže: korózia ventilov napúšťania a vypúšťania, zablokovanie poistného ventilu atd.The protection of these devices against moisture is very important, as water can impair the performance of these devices and threaten the use of the tank: corrosion of the inlet and drain valves, safety valve blocking, etc.

Tieto zariadenia sú obvykle uložené v šachte kruhového alebo obdĺžnikového prierezu, ktorej vstupný otvor je nad úrovňou terénu a ktorá sa dotýka kovového plášťa nádrže.These devices are usually housed in a shaft of circular or rectangular cross-section whose inlet opening is above ground level and which touches the metal shell of the tank.

Aby sa dosiahlo nepriepustnosti medzi plášťom nádrže, ktorý musí odolávať tlaku plynu, a šachtou, sú používané rôzne metódy:Various methods are used to achieve leakage between the shell of the tank, which must withstand gas pressure, and the shaft:

a) Privarenie steny šachty k plášťu nádrže: toto rie1 šenie má rad technických nevýhod, spôsobených jednak tým, že sa jedná o nádobu pod tlakom a tiež obtiažností prispôsobenia na hornú čast nádoby.a) Welding the shaft wall to the shell of the tank: this solution has a number of technical disadvantages due to both the pressurized container and the difficulty of adapting to the top of the container.

b) mechanickou fixáciou dolnej časti steny šachty a jej utesnenia pomocou tmelu; aj ked toto riešenie je výhodné svojou nízkou cenou, nedovoľuje 2aistiť skutočné utesnenie šachty.b) mechanically fixing the lower part of the shaft wall and sealing it with sealant; even though this solution is advantageous due to its low price, it does not allow for a real shaft seal.

Podstata vynálezuSUMMARY OF THE INVENTION

Vynález si kladie za cieľ odstránit tieto nevýhody použitím nádrže, ktorá má kovový plášť a nad ktorou je umiestnená šachta na prídavné zariadenia, pričom plášť nádrže je pokrytý vrstvou polyesteru a/alebo epoxidu, šachta na prídavné zariadenia je z plastu, má tvar zodpovedajúci vonkajšiemu povrchu nádrže a zahrňuje sedlo, pomocou ktorého je prilepená k plášťu nádrže .SUMMARY OF THE INVENTION It is an object of the present invention to overcome these disadvantages by using a tank having a metal shell and over which an accessory shaft is placed, the tank shell being covered with a polyester and / or epoxy layer, the accessory shaft being of plastic, having an external surface and includes a seat by which it is glued to the tank shell.

Týra sa dosiahne veľmi dobrej tesnosti spojenia nádrže a šachty, zvlášť ak plocha prilepenia je aspoň 1000 cm2 a veľmi dobrého pripevnenia šachty na prídavné zariadenia k plášťu nádrže tak, aby nebolo potrebné používať komplikovanú techniku zvárania, ktorá okrem iného prináša nutnosť zahriatia plášťa nádrže. Povlak plášťa zaručuje okrem nepriepustnosti a prípadne aj ochrany proti korózii tiež dobré prilepenie šachty. Ochrana proti korózii už bola známa napríklad z dokumentu Pétrole informations č. 89 (október 1993, strany 15 až 17). Dobré prilepenie v tomto dokumente nebolo uvažované a ani by nemohlo byť dosiahnuté, lebo povlak plášťa bol sám ešte zakrytý plsteným obalom a naviac nebolo uvažované sedlo, ktoré umožňuje získať veľkú plochu prilepenia.Tire is achieved by a very good tightness of the tank-shaft connection, especially if the gluing area is at least 1000 cm 2 and very good attachment of the shaft to the attachments to the tank shell, avoiding the need to use complicated welding techniques. In addition to impermeability and possibly corrosion protection, the casing coating also guarantees good adhesion of the shaft. Corrosion protection has already been known, for example, from Pétrole informations no. 89 (October 1993, pages 15-17). Good bonding in this document has not been considered and could not be achieved because the sheath coating was itself still covered with a felt wrap and, moreover, a saddle that allows a large area of sticking was not considered.

Povlak plášťa nádrže môže byť bud z polyesteru alebo z epoxidu a alebo postupne v tomto poradí z epoxidu pokrytého vrstvou polyesteru. Povlak môže mať výhodne hrúbku od 60 do 300 mikrónov a alebo každý z povlakov epoxidu a polyesteru môže mať túto hrúbku. Povlak epoxidu môže s výhodou obsahovať zinok, slúžiaci na ochranu proti korózii.The shell of the tank may be either of polyester or epoxy, or sequentially of an epoxy coated polyester layer, respectively. The coating may preferably have a thickness of 60 to 300 microns, or each of the epoxy and polyester coatings may have this thickness. The epoxy coating may preferably contain zinc to protect against corrosion.

Šachta na prídavné zariadenia môže byť z polyetylénu, polypropylénu alebo z iného plastu. S výhodou je vyrobená z polyetylénu s veľkou hustotou.The accessory shaft may be of polyethylene, polypropylene or other plastic. It is preferably made of high density polyethylene.

Podľa jedného spôsobu uskutočnenia sa šachta skladá z valcového tela a časti, ktorá vytvára sedlo, prilepené k telu.According to one embodiment, the shaft comprises a cylindrical body and a part that forms a seat glued to the body.

Ako lepidlo je možné použiť dvojzložkové epoxidové lepidlo, ktoré je veľmi tvrdé a veľmi pevné a tiež veľmi odolné voči vode a voči väčšine chemických látok a alebo jednozložkové polyuretánové lepidlo, ktoré zostáva pružné a elastické a ktoré zaručuje dobré spojenie na základe hrúbky aplikovaného pásu a alebo lepiacu pásku, ktorá zostáva pružná a elastická a ktorú je ľahké použiť.The adhesive may be a two-component epoxy adhesive which is very hard and very strong and also very resistant to water and most chemicals, or a one-component polyurethane adhesive which remains elastic and elastic and which guarantees good bonding based on the thickness of the applied strip and an adhesive tape that remains flexible and elastic and easy to use.

This accessory shaft 3 is formed by a body which continues downwardly through the seat 4, which is adjacent to the outer surface of the tank 1. The underside of the seat 4 is glued to the tank χ.

Na obr. S je znázornená nádrž X a prídavné zariadenia S, šachta 3 na prídavné zariadenia zahrňujúce sedlo X, ktoré je prilepené' svojou relatívne veľkou spodnou stranou na nádrž X.In FIG. S shows the tank X and the attachment devices S, the attachment shaft 3 comprising a seat X, which is glued to the tank X with its relatively large underside.

Na obr. 3 sa šachta na prídavné zariadenia skladá z dvoch častí, to je z tela X na ktoré je prilepená časť 4, vytvárajúca sedlo, ktoré je samo prilepené na nádrž 1.In FIG. 3, the attachment shaft comprises two parts, that is, a body X to which the part 4 is glued, forming a seat which is itself glued to the tank 1.
