Description

Invenţia se referă la sisteme de distribuire a gazelor, în special la subansambluri de alimentare cu gazpentru consumatori casnici, şi poate fi utilizată în clădiri industriale şi civile. The invention relates to gas distribution systems, in particular to gas supply subassemblies for domestic consumers, 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, totodată toate elementele constructive se află în aer liber, şi nu sunt protejate de factorii climatici externi [2]. Also, a gas supply installation is known, in which all interconnections between elements are made through flanges, while all structural elements are located outdoors, and are not protected from external climatic factors [2].

Dezavantajele soluţiei cunoscute constau în aceea că elementele constructive se află în aer liber, totodată contorul de gaz nu este dotat cu modul de transfer al datelor online, iar accesul persoanelor neautorizate la instalaţia de alimentare cu gaz nu este limitată, sporind riscul de accidente şi complicând procesul de exploatare a acesteia. În plus, aflarea contorului în aer liber sporeşte riscul de înregistrare a datelor eronate referitoare la consumul de gaz. The disadvantages of the known solution are that the constructive elements are located outdoors, the gas meter is not equipped with an online data transfer mode, and the access of unauthorized persons to the gas supply installation is not limited, increasing the risk of accidents and complicating the process of its operation. In addition, the location of the meter outdoors increases the risk of recording erroneous data regarding gas consumption.

Problema tehnică pe care o rezolvă invenţia propusă constă în sporirea securităţii pe parcursul procesului de exploatare a subansamblului revendicat prin izolarea elementelor constructive, inclusiv a contorului de gaz şi modulului de transfer al datelor, de accesul persoanelor neautorizate, sporirea duratei de funcţionare şi asigurarea preciziei de preluare a datelor referitoare la consumul de gaz. The technical problem solved by the proposed invention consists in increasing security during the operation process of the claimed subassembly by isolating the constructive elements, including the gas meter and the data transfer module, from access by unauthorized persons, increasing the operating time and ensuring the accuracy of data acquisition regarding gas consumption.

Problema se rezolvă prin aceea că subansamblul de alimentare cu gaz pentru consumatori casnici, conform invenţiei, conţine un dulap cu orificii de montare şi o uşă, montată articulat prin intermediul unor balamale cu posibilitatea fixării în poziţie deschisă prin intermediul unei tije. În interiorul dulapului este montat un contur de alimentare cu gaz, care este compus dintr-o conductă de alimentare, la care este racordat prin filet un robinet, conectat la un filtru de gaz prin intermediul unui racord semiolandez. La partea opusă a filtrului de gaz este montată prin filet o ţeavă ramificată cu o intrare şi două capete, la unul din care este montat printr-un robinet un manometru, iar la celălalt capăt este montat prin filet un racord semiolandez sub un unghi drept, unit cu un reglator de presiune, la partea opusă a căruia printr-un racord semiolandez este montat un robinet, conectat la o ţeavă, capătul opus al căreia este unit printr-un racord semiolandez cu un contor de gaz, la ieşirea căruia este montată printr-un racord semiolandez o conductă de evacuare. Pe contorul de gaz este montat un modul de transfer al datelor. The problem is solved by the fact that the gas supply subassembly for domestic consumers, according to the invention, contains a cabinet with mounting holes and a door, mounted articulated by means of hinges with the possibility of fixing in the open position by means of a rod. Inside the cabinet is mounted a gas supply contour, which is composed of a supply pipe, to which a tap is connected by thread, connected to a gas filter by means of a half-Dutch connection. On the opposite side of the gas filter, a branched pipe with an inlet and two ends is threaded, on one of which a pressure gauge is mounted via a tap, and on the other end, a right-angle half-Dutch fitting is threaded, connected to a pressure regulator, on the opposite side of which a half-Dutch fitting is mounted, connected to a pipe, the opposite end of which is connected via a half-Dutch fitting to a gas meter, at the outlet of which an exhaust pipe is mounted via a half-Dutch fitting.
