Description

Invenţia se referă la sisteme de distribuire a gazelor, în special la subansambluri de alimentare cu gaz, şi poate fi utilizată în clădiri industriale şi civile. The invention relates to gas distribution systems, in particular to gas supply subassemblies, and can be used in industrial and civil buildings.

Este cunscut un subansamblu de intrare şi ieşire a conductei de gaze de polimer şi procedeul de confecţionare a acestuia, care constau în aceea că includ îmbinarea nedemontabilă a ţevilor de oţel şi de polimer şi o manta metalică cilindrică cu un strat termoizolant, care cuprinde porţiunea de lucru a îmbinării nedemontabile şi porţiunile ţevilor de oţel şi de polimer aderente acesteia. Mantaua metalică este executată ermetică, fiind dotată deasupra cu o flanşă oarbă, acoperită din exterior cu un strat de mastic bitumoatactic, şi dedesubt cu o flanşă oarbă, acoperită din exterior cu un strat de material polimer. Mantaua metalică este umplută cu stratul termoizolant din partea ţevii de polimer cu formarea în partea superioară a mantalei, a unei camere de aer, care este dotată cu un ştuţ cu buşon filetat. Lungimea segmentului ţevii de polimer a îmbinării nedemontabile este de 800...3000 mm. Segmentul ţevii de polimer poate fi dotat cu o cutie gofrată rigidă de polimer, unită etanş cu mantaua metalică [1]. A polymer gas pipeline inlet and outlet subassembly and the manufacturing process thereof are known, which consist in that they include a non-removable joint of steel and polymer pipes and a cylindrical metal jacket with a heat-insulating layer, which comprises the working portion of the non-removable joint and the portions of steel and polymer pipes adhering to it. The metal jacket is made hermetic, being equipped on top with a blind flange, covered on the outside with a layer of bituminous mastic, and below with a blind flange, covered on the outside with a layer of polymer material. The metal jacket is filled with the heat-insulating layer from the polymer pipe side with the formation in the upper part of the jacket of an air chamber, which is equipped with a threaded plug. The length of the polymer pipe segment of the non-removable joint is 800...3000 mm. The polymer pipe segment can be equipped with a rigid polymer corrugated box, sealed with the metal jacket [1].

Dezavantajul soluţiei cunoscute constă în aceea că aceasta nu permite demontarea ţevilor, ceea ce limitează utilizarea ei în ansamblurile demontabile, iar interschimbabilitatea subansamblurilor şi pieselor interconectate prin metoda cunoscută este practic imposibilă. The disadvantage of the known solution is that it does not allow the dismantling of the pipes, which limits its use in demountable assemblies, and the interchangeability of subassemblies and parts interconnected by the known method is practically impossible.

De asemenea, este cunoscută o instalaţie de alimentare cu gaz, în care toate interconexiunile dintre elemente sunt efectuate prin flanşe, iar purjarea nu poate fi efectuată decât prin dezasamblarea unuia dintre ele [2]. Also, a gas supply installation is known, in which all interconnections between elements are made through flanges, and purging can only be performed by disassembling one of them [2].

Dezavantajele soluţiei cunoscute constau în aceea că interconexiunea elementelor constructive este efectuată prin flanşe, ceea ce conduce la mărirea dimensiunilor de gabarit ale instalaţiei, complică procesul de mentenanţă şi deservirea tehnică a acesteia. Totodată lipsa conductei de purjare conduce la diminuarea securităţii de exploatare a instalaţiei, la mărirea duratei procesului de mentenanţă şi complexităţii acestuia. The disadvantages of the known solution are that the interconnection of the structural elements is carried out through flanges, which leads to an increase in the overall dimensions of the installation, complicates the maintenance process and its technical service. At the same time, the lack of a purge pipe leads to a decrease in the operational safety of the installation, to an increase in the duration of the maintenance process and its complexity.

Problema tehnică pe care o rezolvă invenţia propusă constă în posibilitatea de a efectua conexiuni uşor demontabile între elementele subansamblului în timpul lucrărilor de mentenanţă, prin intermediul racordurilor olandeze, de a eficientiza procesul de montare şi demontare, în caz de necesitate, a elementelor subansamblului, şi de a micşora dimensiunile de gabarit ale acestuia. The technical problem solved by the proposed invention consists in the possibility of making easily removable connections between the elements of the subassembly during maintenance work, by means of Dutch connections, of streamlining the process of assembly and disassembly, if necessary, of the elements of the subassembly, and of reducing its overall dimensions.

Problema se rezolvă prin aceea că subansamblul de alimentare cu gaz conţine un dulap cu orificii de montare şi o uşă fixată articulat prin intermediul unor balamale, în interiorul căruia sunt montate două contururi identice de alimentare cu gaz, fiecare din ele fiind compus dintr-o conductă de alimentare, la care este racordat prin filet un robinet, la capătul opus al căruia este racordat prin filet un racord de trecere, unit prin filet cu un filtru de gaz, la intrarea şi ieşirea căruia sunt montaţi prin filet câte un manometru, manometrul de la intrare fiind montat pe o conductă de tip T pentru purjarea ambelor contururi prin intermediul unei conducte de purjare. Filtrul de gaz este unit cu un reglator de presiune prin filet cu ajutorul unui racord olandez. La partea opusă a reglatorului de presiune, tot prin filet cu ajutorul unui racord olandez, este unită o conductă intermediară de tip T, pe care este montat un manometru, la capătul opus al conductei intermediare de tip T fiind racordat prin filet cu ajutorul unui racord de trecere un robinet, capătul opus al căruia este unit prin filet cu o conductă de evacuare. The problem is solved by the gas supply subassembly comprising a cabinet with mounting holes and a hinged door, inside which two identical gas supply circuits are mounted, each of which is composed of a supply pipe, to which a tap is threadedly connected, at the opposite end of which a through-connection is threadedly connected, connected by thread to a gas filter, at the inlet and outlet of which a pressure gauge is threadedly mounted, the inlet pressure gauge being mounted on a T-type pipe for purging both circuits by means of a purge pipe. The gas filter is connected to a pressure regulator by thread using a Dutch fitting. On the opposite side of the pressure regulator, also through a thread using a Dutch connection, a T-type intermediate pipe is connected, on which a pressure gauge is mounted, at the opposite end of the T-type intermediate pipe a valve is connected through a thread using a through-connection, the opposite end of which is connected through a thread to an exhaust pipe.

Rezultatul tehnic al invenţiei propuse constă în aceea că aceasta permite de a efectua conexiuni uşor demontabile între elementele subansamblului în timpul lucrărilor de mentenanţă, prin intermediul racordurilor olandeze, de a eficientiza procesul de montare şi demontare, în caz de necesitate, a elementelor subansamblului, şi de a micşora dimensiunile de gabarit ale acestuia faţă de cele clasice cu aproximativ de trei ori. Totodată, micşorarea dimensiunilor de gabarit ale subansamblului conduce la scăderea masei per unitate, ceea ce sporeşte numărul de unităţi transportate într-un mijloc de transport de la locul producerii acestora până la destinaţie. De asemenea, invenţia permite de a micşora durata de timp pentru asamblarea elementelor subansamblului în timpul producerii, dar şi în timpul montării pe şantier, întrucât lipsesc asamblările cu flanşe, care presupun înşurubarea a cel puţin patru buloane cu piuliţe pentru fiecare îmbinare, ceea ce nu este caracteristic pentru racordurile olandeze. The technical result of the proposed invention is that it allows to make easily removable connections between the elements of the subassembly during maintenance work, by means of Dutch joints, to streamline the process of assembly and disassembly, if necessary, of the elements of the subassembly, and to reduce its overall dimensions compared to the classic ones by approximately three times. At the same time, reducing the overall dimensions of the subassembly leads to a decrease in the mass per unit, which increases the number of units transported in a means of transport from the place of their production to the destination. Also, the invention allows to reduce the time for assembling the elements of the subassembly during production, but also during assembly on the construction site, since flange assemblies are missing, which require screwing in at least four bolts with nuts for each joint, which is not characteristic of Dutch joints.

La capătul opus al conductei intermediare de tip T 10 este racordat prin filet cu ajutorul racordului de trecere 6 robinetul 5, capătul opus al căruia este unit prin filet cu conducta de evacuare 12. The gas supply subassembly (fig. 1-6) contains the cabinet 1 with mounting holes 15, 16 and the door 2 hingedly fixed by means of hinges 3, inside which two identical gas supply contours are mounted. Each contour is composed of the supply pipe 4, to which the valve 5 is connected by thread, to the opposite end of which the through-flow connection 6 is connected by thread, connected by thread to the gas filter 7, at the inlet and outlet of which a pressure gauge 11 is mounted by thread, the pressure gauge 11 at the inlet being mounted on the T-type pipe 13 for purging both contours by means of the purging pipe 14. The gas filter 7 is connected to the pressure regulator 8 by thread using the Dutch connection 9. To the opposite side of the pressure regulator 8, also by thread using the Dutch connection 9, the intermediate pipe of the T-type 10 is connected, on which the pressure gauge 11 is mounted. To the opposite end of the intermediate pipe of the T-type 10 is connected by thread using the through-flow connection 6 the valve 5, the opposite end of which is connected by thread with the exhaust pipe 12.

Subansamblul de alimentare cu gaz funcţionează în modul următor. The gas supply subassembly operates in the following manner.

Asamblarea primului contur: Assembling the first contour:

Pasul I: Iniţial, la reglatorul de presiune 8 se înşurubează din ambele părţi racordurile olandeze 9, după care, racordul olandez 9 de la intrarea în reglatorul de presiune 8 se înşurubează la filtrul de gaz 7, la intrarea căruia este înşurubat racordul de trecere 6, la care se înşurubează robinetul 5. Tot la robinetul 5 se înşurubează conducta de alimentare 4. Step I: Initially, the Dutch connections 9 are screwed onto the pressure regulator 8 on both sides, after which the Dutch connection 9 at the inlet of the pressure regulator 8 is screwed onto the gas filter 7, to the inlet of which the through connection 6 is screwed, to which the valve 5 is screwed. Also to the valve 5, the supply pipe 4 is screwed.

Pasul II: Racordul olandez 9 de la ieşirea din reglatorul de presiune 8 se înşurubează la conducta intermediară de tip T 10, la care se înşurubează racordul de trecere 6, la care se înşurubează robinetul 5. Tot la robinetul 5 se înşurubează conducta de evacuare 12. Step II: The Dutch connection 9 from the outlet of the pressure regulator 8 is screwed to the intermediate T-type pipe 10, to which the through connection 6 is screwed, to which the valve 5 is screwed. Also to the valve 5, the discharge pipe 12 is screwed.

Asamblarea celui de-al doilea contur se efectuează analogic cu asamblarea primului contur. The assembly of the second contour is carried out analogously to the assembly of the first contour.

Pasul III: Se deschide uşa 2 a dulapului 1, iar în interiorul acestuia, în poziţie orizontală, orientate paralel între ele, se montează ambele contururi prin orificiile de montare 15. Step III: Open door 2 of cabinet 1, and inside it, in a horizontal position, oriented parallel to each other, mount both contours through the mounting holes 15.

Pasul IV: De ambele contururi, prin filet la conducta de tip T 13 se montează conducta de purjare 14, capătul opus al căreia iese în exteriorul dulapului 1 prin orificiul de montare 16. Etapa finală presupune montarea prin filet a manometrelor 11 pe filtrul de gaz 7 şi pe conducta intermediară de tip T 10. Step IV: On both contours, through the thread to the T-type pipe 13, the purge pipe 14 is mounted, the opposite end of which exits outside the cabinet 1 through the mounting hole 16. The final stage involves the threaded mounting of the pressure gauges 11 on the gas filter 7 and on the intermediate T-type pipe 10.
