Sistema de fixação para tubo de gás em fogõesStove gas pipe fixing system

Campo da invençãoField of the invention

Esta invenção diz respeito a um sistema de fixação para o tubo de gás noregistro ou no venturi da mesa de fogões a gás, consistindo de um grampocom duplo engate cuja parte central envolve a extremidade do tubo que pe-netra no registro do gás ou do venturi, promovendo o engate em duas pro-jeções laterais previstas no corpo do registro ou do venturi. Dessa forma,com duplo engate, o tubo do gás fica alinhado com o elemento no qual seconecta.This invention relates to a clamping system for the vent gas pipe or venturi of the gas cooker table, consisting of a double coupling clamp whose central part surrounds the end of the pipe that enters the gas or venturi registration. by engaging in two lateral projections provided on the body of the register or venturi. In this way, with double coupling, the gas pipe is aligned with the element to which it connects.

Histórico da invençãoInvention History

Atualmente, no estado da técnica, a conexão entre o tubo gás e o registro écomumente feita com o uso de elementos com roscas, o que requer acessó-rios tais como arruelas e vedantes químicos para evitar vazamentos de gásnessas uniões. Esse sistema tende a encarecer o produto final, considerandotanto o custo dos componentes como também o da mão de obra empregada.Em outra alternativa também conhecida, usa-se uma presilha de chapa parafixar o tubo no registro. Neste caso, a presilha utilizada para prender o tubono registro tem um engate precário, uma vez que a fixação se dá apenas porum lado do registro, o que permite um movimento lateral do tubo e, portan-to, com possibilidade de vazamento de gás nessa conexão.Em outra fixação semelhante, em vez de presilha de chapa metálica, utilizaum grampo de arame com engate apenas por um lado do registro. Nessecaso, também ocorre o mesmo inconveniente apontado com a presilha dechapa, isto é: desalinhamento lateral entre o tubo e o registro e que podeprovocar vazamento de gás na união.Currently, in the prior art, the connection between the gas pipe and the registration is commonly made with the use of threaded elements, which requires accessories such as washers and chemical seals to prevent leakage of these joints. This system tends to make the final product more expensive, considering both the cost of the components as well as the labor employed. In another well-known alternative, a sheet metal clip is used to secure the pipe to the register. In this case, the clamp used to hold the registration tube has a precarious engagement, since the attachment is only on one side of the registration, which allows a lateral movement of the pipe and, therefore, with the possibility of gas leakage in this one. In another similar fixation, instead of sheet metal clip, it uses a wire clip that engages only on one side of the register. In this case, the same inconvenience pointed out with the tab clamp also occurs, that is: lateral misalignment between the pipe and the register and that can cause gas leakage in the union.

A invenção propõe simplificar e ao mesmo tempo melhorar a conexão entreo tubo e o registro a fim de evitar os inconvenientes apontados no estado datécnica através de um sistema de fixação que garanta o alinhamento da tu-bulação e minimize a possibilidade de incidentes de vazamentos.The invention proposes to simplify and at the same time improve the connection between the pipe and the register in order to avoid the drawbacks pointed out in the technical state by means of a clamping system which ensures alignment of the pipe and minimizes the possibility of leakage incidents.

Descrição detalhada da invençãoDetailed Description of the Invention

Esta invenção descreve sistema de conexão para utilização na fixação dotubo de gás (1) de fogões a gás, promovendo tanto a firme conexão quantoo alinhamento dos elementos envolvidos. O sistema promove a integraçãoentre o tubo de gás (1) com o registro (2) do fogão ou com o venturi (3) damesa do fogão, utilizando um grampo (4) com duplo engate, sendo que suaparte central (4a) envolve a extremidade do tubo (1) que penetra no registro(2) ou no venturi (3), cujas extremidades engatam em duas projeções late-rais (5) previstas no corpo do registro (2) ou do venturi (3).Com o duplo engate, o tubo de gás (1) fica alinhado com o registro (2) oucom o venturi (3), dependendo da aplicação, minimizando a possibilidadede vazamento de gás, além de incorrer em menor custo, mais rapidez esimplificação no processo de montagem do conjunto.O grampo fixador (4) do tubo de gás (1) apresenta, em sua porção central,uma curvatura em forma de U (4a) que abraça o tubo (1) por trás da expan-são circular do tubo (1). As duas extremidades do grampo fixador (4) dotubo (1) se projetam e se curvam pelos lados do corpo cilíndrico do registro(2) ou do venturi (3), curvando-se novamente logo adiante e envolvendo parcialmente as duas projeções laterais (5) do corpo cilíndrico do registro (2) ou do venturi (3). O grampo (4), assim montado, configura a fixação do tubo no registro (2) ou no venturi (3), impedindo que se destaquem naturalmente, já que a expansão circular do tubo de gás (1) tem o diâmetro maior que a porção em U (4a) do grampo (4), além de a dita expansão ficar por dentro da extremidade do registro (2) ou do venturi (3), onde se aloja o anel de vedação.This invention discloses a connection system for use in the gas tube fixation (1) of gas cookers, promoting both the tight connection and the alignment of the elements involved. The system promotes the integration between the gas pipe (1) with the stove register (2) or with the stove's venturi (3) using a double-clamp clamp (4), with its central part (4a) involving the end of the tube (1) that penetrates the register (2) or the venturi (3), whose ends engage two lateral projections (5) provided in the registration (2) or venturi (3) body. coupling, the gas pipe (1) is aligned with the registration (2) or venturi (3), depending on the application, minimizing the possibility of gas leakage, besides incurring lower cost, faster and simplification in the process of assembling the gas. The clamp (4) of the gas pipe (1) has, in its central portion, a U-shaped curvature (4a) which embraces the pipe (1) behind the circular expansion of the pipe (1). . The two ends of the fastener clamp (4) dotubo (1) protrude and bend from the sides of the cylindrical body of the register (2) or the venturi (3), bending again just ahead and partially enveloping the two lateral projections (5). ) of the cylindrical body of the register (2) or the venturi (3). The clamp (4), thus assembled, configures the fixation of the pipe in the register (2) or venturi (3), preventing them from being naturally detached, since the circular expansion of the gas pipe (1) is larger than the diameter U-portion (4a) of the clamp (4), in addition to said expansion being inside the end of the register (2) or the venturi (3), where the sealing ring is housed.
