Description
"VÁLVULA ANGULAR A 90° COM FECHAMENTO INTERNO/EXTERNO ACOPLADA A UM REDUTOR BLINDADO ACIONADO ATRAVÉS DE COROA E PINHÃO COMANDADO POR MOTOR ELÉTRICO/HIDRÁULICO COM SUPORTE PARA SUSTENTAÇÃO DE PNEUTORQUE". "90 ° ANGLE VALVE WITH INTERNAL / EXTERNAL CLOSURE COUPLED TO A SHIELD REDUCED THROUGH CROWN AND HYDRAULIC CONTROLLED PINION WITH SUPPORT FOR TIRE SUPPORT".
Refere-se a presente patente de invenção a uma "VÁLVULA ANGULAR A 90° COM FECHAMENTO INTERNO/EXTERNO ACOPLADA A UM REDUTOR BLINDADO ACIONADO ATRAVÉS DE COROA E PINHÃO COMANDADO POR MOTOR ELÉTRICO/HIDRÁULICO COM SUPORTE PARA SUSTENTAÇÃO DE PNEUTORQUE", que foi desenvolvida para proporcionar uma melhor manutenção no equipamento e impedir a entrada de material no interior do castelo, além de permitir uma rápida abertura e um rápido fechamento da válvula através do redutor que é comandado através de um motor elétrico/hidráulico, ou um pneutorque ou manualmente com total segurança para o operador. This patent relates to a "90 ° ANGLE VALVE WITH INTERNAL / EXTERNAL CLOSURE COUPLED TO A BLOCKED REDUCED THROUGH CROWN AND HYDRAULIC CONTROLLED PINION WHICH HAS BEEN DEVELOPED FOR PNEUTOR SUPPORT" provide better equipment maintenance and prevent material from entering the bonnet, as well as allow quick opening and quick closing of the valve through the reducer that is controlled by an electric / hydraulic motor, or a pneumatic or manually with full safety for the operator.
As válvulas de alta pressão empregadas em tubulações condutoras, principalmente de polpa de bauxita com mistura cáustica e cal, com temperatura elevada para a extração de alumina, são em sua totalidade isentas de uma blindagem protetora, o que tem gerado muitos acidentes com os operadores devido ao vazamento do liquido contido na tubulação ou dos produtos utilizados para a limpeza quando da necessidade de reparos das mesmas. The high pressure valves used in conductive piping, mainly of caustic mixture of lime and bauxite, with high temperature for the extraction of alumina, are totally free of protective shielding, which has caused many accidents with the operators due to leakage of liquid contained in the pipeline or cleaning products when repairs are required.
Outro inconveniente encontrado nessas válvulas está relacionado ao seu sistema de gaxetas utilizadas entre o corpo da válvula, pois não impedem o deslocamento do eixo principal ocasionando uma excentricidade muito grande entre o redutor e válvula, além das válvulas atuais permitirem
que o material quando da parada das mesmas penetrem no castelo danificando esta parte da bomba, que não conta com um esmerilhador. Another drawback found in these valves is related to their system of gaskets used between the valve body, as they do not prevent the displacement of the main shaft causing a very large eccentricity between the reducer and valve, besides the current valves allow that when the material stops, they penetrate the bonnet damaging this part of the pump, which does not have a grinder.
Outro ponto que devemos destacar está relacionado a.o fechamento das válvulas a partir do redutor quando da ocorrência de pane no motor elétrico e da necessidade de utilizar um pneutorque, estes redutores não possuem um suporte para que este equipamento seja acoplado, obrigando que o operador promova o fechamento da válvula segurando o pneutorque com os braços até o fechamento total da válvula, ocorre que este equipamento possui um peso elevado e sua disposição construtiva não permite uma boa empunhadura, além disso, esse fechamento, dependendo do caso, pode levar horas, o que torna o serviço lento e laborioso e impede de o operador desenvolva outra função, necessitando, muitas vezes, de vários operários para este serviço. Another point that should be highlighted is related to the closing of the valves from the gear unit when the electric motor breaks down and the need to use a tire, these gear units do not have a support for this equipment to be coupled, requiring the operator to promote the closing the valve holding the tire arm with the arms until the valve is fully closed, this equipment has a high weight and its constructive arrangement does not allow a good grip, and this closing, depending on the case, can take hours, which It makes the service slow and laborious and prevents the operator from performing another function, often requiring several workers for this service.

Com base no descrito e ilustrado é dado a perceber - que a Based on what is described and illustrated it is given to realize - that
"VÁLVULA ANGULAR A 90° COM FECHAMENTO INTERNO/EXTERNO ACOPLADA A UM REDUTOR BLINDADO ACIONADO ATRAVÉS DE COROA E PINHÃO COMANDADO POR MOTOR ELÉTRICO/HIDRÁULICO COM SUPORTE PARA SUSTENTAÇÃO DE PNEUTORQUE" a válvula em questão apresenta um revolucionário sistema de castelo que incorpora internamente um retentor alojado abaixo das gaxetas que mantêm a concentricidade do eixo longitudinal de esmerilhamento, além de impedir a passagem de material oriundo do corpo receptor para o interior do castelo, com isso o operador pode trabalhar com segurança uma vez que o compartimento de gaxetas é alcançado através da porta de inspeçâo não havendo necessidade de se desmontar o equipamento para troca das mesmas. "90 ° ANGLE VALVE WITH INTERNAL / EXTERNAL CLOSURE COUPLED TO A SHIELD REDUCED THROUGH CROWN AND HYDRAULIC CONTROLLED PINION WITH SUPPORT FOR PNEUTORK SUPPORT" the in-house valve features a revolutionary inbuilt system housed below the gaskets that maintain the concentricity of the longitudinal grinding axis and prevent material from the receiving body from entering the bonnet, the operator can safely work once the gasket compartment is reached through the inspection door and there is no need to disassemble the equipment to replace them.
Devemos salientar ainda que a sede e a contra sede são fabricadas em aço cromo CR 40 e temperadas por indução, esse tratamento permite que as mesmas sejam reusinadas e novamente temperadas. A introdução de uma escala possibilita que o operador possa saber com certeza se a válvula está aberta ou fechada, pois o ponteiro posicionado sobre um número alto indica que a mesma encontra-se aberta e sobre o número zero que a mesma encontra-se fechada, esta prática proporciona uma maior segurança na manutenção do equipamento. It should also be noted that the seat and back seat are made of chrome steel CR 40 and induction hardened, this treatment allows them to be reused and tempered again. Entering a scale enables the operator to know with certainty whether the valve is open or closed, as the pointer positioned over a high number indicates that it is open and over the number zero that it is closed, This practice provides greater safety in equipment maintenance.
Outro fator de grande relevância encontra-se na blindagem do castelo e na lubrificação do eixo longitudinal de esmerilhamento que
impedem que produtos se acumulem em seu interior, o que possibilita o manuseio do eixo após a manutenção sem qualquer alteração. Another very important factor is the bonnet armor and the lubrication of the grinding prevent products from accumulating inside, which enables shaft handling after maintenance without any change.
Tudo isso aliado a um redutor desenvolvido especificamente para proporcionar um melhor desempenho na desobstrução da válvula através de um acionamento que conta com três formas distintas, ou seja: através de um motor elétrico/hidráulico, de um pneutorque acionado através de ar comprimido ou manualmente através de um volante utilizado na falta de energia elétrica, All this combined with a gear unit specifically designed to provide better valve clearance performance through a drive that comes in three different forms, namely: via an electric / hydraulic motor, a pneumatic driven by hand or through of a steering wheel used in the absence of electricity,
O redutor possui rolamento disposto na secção inferior da bucha que permite um melhor giro e perfeito esmerilhamento da válvula e impede que a bucha toque no castelo, sendo que o rolamento superior impede que esta seja deslocada do eixo principal aumentando a vida útil do equipamento, além de contar com uma porca de travamento vertical que permite seu ajuste em relação à coroa que juntamente com o rolamento superior impede seu deslocamento do centro de giro. The gear unit has a bearing arranged in the lower section of the bushing that allows better turning and perfect grinding of the valve and prevents the bushing from touching the bonnet, while the upper bearing prevents it from being displaced from the mainshaft, increasing the service life of the equipment. It has a vertical locking nut that allows its adjustment in relation to the crown that together with the upper bearing prevents its displacement of the center of rotation.
Podemos destacar ainda que a utilização de rolamentos de ajustes horizontais que apoiam o eixo de comando do redutor impedem sua excentricidade aumentando a suavidade do movimento de rotação. It is also noteworthy that the use of horizontal adjustment bearings that support the drive shaft of the gearbox prevent its eccentricity increasing the smoothness of the rotation movement.
Outra grande vantagem encontrada no equipamento está relacionada ao suporte de sustentação do pneutorque, pois a inclusão desse dispositivo permite que o mesmo trabalhe sem a necessidade de ser sustentado pelo operador, permitindo que após o serviço executado seja removido e fique preso a própria caixa do redutor através de corrente, com isso evita-se acidentes e o esforço desnecessário do operador que fica liberado para outras atividades. Another great advantage found in the equipment is related to the tire support bracket, because the inclusion of this device allows it to work without the need to be supported by the operator, allowing after the service performed to be removed and the gearbox housing itself is stuck. through current, this avoids accidents and unnecessary operator effort that is released for other activities.
Vale lembrar ainda que o acionamento da trava porca permite que o eixo longitudinal passe a girar louco, facilitando o esmerilhamento manual
interno da válvula para retirada do material incrustado em seu interior e, consequentemente, diminuindo o esforço físico do operador. It is also worth remembering that the actuation of the lock nut allows the longitudinal axis to turn crazy, facilitating manual grinding. inside the valve to remove the encrusted material inside and, consequently, reducing the operator's physical effort.
O redutor ora reivindicado possui uma disposição inovadora em seu aspecto geral, pois além das vantagens acima descritas conta ainda com uma caixa de redutor totalmente blindada que impede a ocorrência de acidentes, por ser inovador e até então não compreendidas no estado da técnica que enquadra-se perfeitamente dentro dos critérios que definem a patente de invenção. São as seguintes suas reivindicações.
