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 bitumotactic 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, inclusiv şi conexiunile la reglatoarele de presiune, 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, including connections to pressure regulators, 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. De asemenea, conectarea la reglatoarele de presiune în circuit prin flanşe conduce la complexitatea constructivă a instalaţiei, deoarece între flanşe sunt prezente garnituri, care necesită mai multe operaţii consecutive pentru demontarea corectă şi presupune riscul de apariţie a scurgerilor de gaz în timplul funcţionării instalaţiei. 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. Also, the connection to the pressure regulators in the circuit through flanges leads to the construction complexity of the installation, because between the flanges there are gaskets, which require several consecutive operations for correct disassembly and entail the risk of gas leaks during the operation of the installation.

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, conectarea la reglatoarele de presiune în circuit fiind efectuată doar prin filet, eficientizând etanşietatea subansamblului, precum şi micşorarea dimensiunilor 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, the connection to the pressure regulators in the circuit being made only by thread, making the subassembly more efficient, as well as reducing its overall dimensions.

Problema se rezolvă prin aceea că subansamblul de alimentare cu gaz conţine un dulap cu orificii de montare şi două uşi fixate articulat prin intermediul unor balamale, în interiorul căruia sunt montate două contururi de alimentare cu gaz, unul de bază A şi altul de avarie B, care sunt unite printr-un racord de alimentare comun la intrare şi un racord de evacuare comun la ieşire. Conturul de bază A este compus din racordul de alimentare comun, la care este racordat prin flanşă un robinet, la capătul opus al căruia este racordat prin flanşă un racord de trecere sub un unghi drept, unit prin flanşă cu un filtru de gaz şi dotat cu un manometru de presiune, la capătul opus al filtrului de gaz fiind montată prin flanşă o ţeavă dotată cu un manometru de presiune şi un racord de conectare la o ţeavă de purjare racordată la ambele contururi A şi B, capătul opus al ţevii fiind asamblat prin filet cu un reglator de presiune, la partea opusă a căruia tot prin filet este montat un racord dotat cu un manometru de presiune, capătul opus al racordului fiind îmbinat prin flanşă cu un robinet, partea opusă a căruia este asamblată prin flanşă cu racordul de evacuare comun. Conturul de avarie B este compus din racordul de alimentare comun, la care este racordat prin flanşă un robinet, la capătul opus al căruia este racordat prin flanşă un filtru de gaz, la capătul opus al căruia este montată prin flanşă o ţeavă dotată cu un manometru de presiune şi un racord de conectare la ţeava de purjare, capătul opus al ţevii fiind asamblat prin filet cu un reglator de presiune, la partea opusă a căruia tot prin filet este montat un racord dotat cu un manometru de presiune, capătul opus al racordului fiind îmbinat prin flanşă cu un racord de trecere sub un unghi drept, partea opusă a căruia este asamblată prin flanşă cu un robinet, unit prin flanşă cu racordul de evacuare comun. The problem is solved by the fact that the gas supply subassembly contains a cabinet with mounting holes and two doors articulated by means of hinges, inside which two gas supply circuits are mounted, one basic A and the other emergency B, which are joined by a common supply connection at the inlet and a common exhaust connection at the outlet. The basic contour A is composed of the common supply connection, to which a valve is connected by a flange, at the opposite end of which a right-angled through-connection is connected by a flange, joined by a gas filter and equipped with a pressure gauge, at the opposite end of the gas filter a pipe equipped with a pressure gauge and a connection to a purge pipe connected to both contours A and B is mounted by a flange, the opposite end of the pipe being assembled by a thread with a pressure regulator, at the opposite side of which a connection equipped with a pressure gauge is also mounted by a thread, the opposite end of the connection being joined by a flange to a valve, the opposite side of which is assembled by a flange with the common exhaust connection. The emergency circuit B is composed of the common supply connection, to which a valve is connected by a flange, at the opposite end of which a gas filter is connected by a flange, at the opposite end of which a pipe equipped with a pressure gauge and a connection to the purge pipe is mounted by a flange, the opposite end of the pipe being assembled by a thread with a pressure regulator, at the opposite side of which a connection equipped with a pressure gauge is also mounted by a thread, the opposite end of the connection being joined by a flange with a right-angled passage connection, the opposite side of which is assembled by a flange with a valve, joined by a flange with the common exhaust connection.

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, conectarea la reglatoarele de presiune în circuit fiind efectuată doar prin filet, eficientizând etanşietatea subansamblului, de a micşora dimensiunile de gabarit ale acestuia cu aproximativ 20% şi costul de producere, de a simplifica transportarea într-un mijloc de transport, de a micşora durata de timp pentru asamblarea elementelor în timpul producerii şi montării pe şantier, fiind utilizate conexiuni prin filet, precum şi de a substitui conturele de bază şi cel de avarie în caz de necesitate. The technical result of the proposed invention is that it allows for easily removable connections between the elements of the subassembly during maintenance work, the connection to the pressure regulators in the circuit being made only by thread, making the subassembly more efficient, reducing its overall dimensions by approximately 20% and the cost of production, simplifying transportation in a means of transport, reducing the time required for assembling the elements during production and installation on the construction site, using thread connections, as well as substituting the basic and emergency contours in case of need.

The emergency circuit B is composed of the common supply connection 4, to which the valve 6 is connected by a flange, to the opposite end of which the gas filter 8 is connected by a flange, to the opposite end of which the pipe 10 equipped with the pressure gauge 9 and the connection connection 11 to the purge pipe 12 are mounted by a flange, the opposite end of the pipe 10 being assembled by a thread with the pressure regulator 13, to the opposite side of which the connection 14 equipped with the pressure gauge 9 is also mounted by a thread, the opposite end of the connection 14 being joined by a flange with the through connection 7 at a right angle, the opposite side of which is assembled by a flange with the valve 6, joined by a flange with the common exhaust connection 5.

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

Asamblarea conturului de bază A: Assembling the basic outline A:

Pasul I: Iniţial, la reglatorul de presiune 13 se înşurubează dintr-o parte ţeava 10 dotată cu manometrul de presiune 9 şi racordul de conectare 11, iar din altă parte racordul 14 de asemenea dotat cu manometrul de presiune 9 şi îmbinat prin flanşă cu robinetul 6. Ulterior, de partea opusă a ţevii 10 este asamblat prin flanşă filtrul de gaz 8, care tot prin flanşă este asamblat cu racordul de trecere 7 fixat prin flanşă cu robinetul 6. Step I: Initially, on one side, the pipe 10 equipped with the pressure gauge 9 and the connection fitting 11 is screwed to the pressure regulator 13, and on the other side, the connection 14 also equipped with the pressure gauge 9 and connected by flange to the valve 6. Subsequently, on the opposite side of the pipe 10, the gas filter 8 is assembled by flange, which is also assembled by flange with the through-connection 7 fixed by flange to the valve 6.

Asamblarea conturului de avarie B: Assembling the fault contour B:

Pasul II: Iniţial, la reglatorul de presiune 13 se înşurubează dintr-o parte ţeava 10 dotată cu manometrul de presiune 9 şi racordul de conectare 11, iar din altă parte racordul 14 de asemenea dotat cu manometrul de presiune 9 şi îmbinat prin flanşă cu racordul de trecere 7, asamblat tot prin flanşă cu robinetul 6. Ulterior, de partea opusă a ţevii 10 este asamblat prin flanşă filtrul de gaz 8, care tot prin flanşă este asamblat cu robinetul 6. Step II: Initially, on one side, the pipe 10 equipped with the pressure gauge 9 and the connection fitting 11 is screwed to the pressure regulator 13, and on the other side, the connection 14 also equipped with the pressure gauge 9 and connected by flange to the through-connection 7, also assembled by flange with the valve 6. Subsequently, on the opposite side of the pipe 10, the gas filter 8 is assembled by flange, which is also assembled by flange with the valve 6.

Pasul III: Presupune asamblarea în paralel a contururilor A şi B prin flanşe cu racordul de alimentare comun 4 la intrare şi racordul de evacuare comun 5 la ieşire. Racordul de evacuare comun 5 se montează dupa ce contururile A şi B unite prin flanşe cu racordul de alimentare comun 4, vor fi montate în dulapul 1 astfel, încât racordul de alimentare 4 să fie introdus în orificiul de montare 15. Ulterior, se montează prin flanşă racordul de evacuare comun 5, fiind poziţionat în orificiul de montare 15. Ultimul pas presupune conectarea ţevii de purjare 12 la contururile A şi B prin intermediul racordurilor de conectare 11 şi fixarea ei în orificiul 16. Step III: It involves the parallel assembly of the contours A and B through flanges with the common supply connection 4 at the inlet and the common exhaust connection 5 at the outlet. The common exhaust connection 5 is mounted after the contours A and B, joined by flanges with the common supply connection 4, are mounted in the cabinet 1 so that the supply connection 4 is inserted into the mounting hole 15. Subsequently, the common exhaust connection 5 is mounted through the flange, being positioned in the mounting hole 15. The last step involves connecting the purge pipe 12 to the contours A and B through the connection connections 11 and fixing it in the hole 16.

Pe parcursul funcţionării subansamblului în regim normal robinetele 6 din conturul B sunt în poziţie închisă, iar cele din conturul A sunt în poziţie deschisă. În caz de situaţii neprevăzute (de exemplu, defecţiuni tehnice pe conturul A), robinetele 6 din conturul A se fixează în poziţie inchisă, iar cele din conturul B se fixează în poziţie deschisă. Astfel, este exclusă întreruperea alimentării cu gaz a clădirii. During normal operation of the subassembly, the 6 valves in circuit B are in the closed position, and those in circuit A are in the open position. In case of unforeseen situations (for example, technical failures in circuit A), the 6 valves in circuit A are fixed in the closed position, and those in circuit B are fixed in the open position. Thus, interruption of the gas supply to the building is excluded.
