Válvula de esfera de soldagem de alta pressão Q61N
The Q61N high-pressure welded ball valve is a valve in which the opening and closing element (bola) is driven by the valve stem and rotates around the axis of the valve stem. It is mainly used to cut off or connect the medium in a pipeline, e também pode ser usado para regulação e controle de fluidos. Em oleodutos, high-pressure welded ball valves are mainly used for cutting off, distribuindo, e mudando a direção do fluxo do meio. It requires only a 90-degree rotation and a very small torque to achieve a tight seal.

They require only a 90-degree rotation and a very small torque to achieve a tight seal. As válvulas de esfera são mais adequadas para aplicações de ligar/desligar e desligar. The main characteristics of welded ball valves are their compact structure, vedação confiável, estrutura simples, and convenient maintenance. The sealing surface and the ball are always in a closed state, making them less susceptible to erosion by the medium. They are easy to operate and maintain, suitable for general working media such as water, solventes, ácidos, e gás natural, and also suitable for media with harsh working conditions such as oxygen, peróxido de hidrogênio, metano, e etileno. They are widely used in various industries. The valve body of a high-pressure welded ball valve can be integral or modular.
Q61N High Pressure Welding Ball Valve Main Advantages
1. Baixa resistência a fluidos: Full-bore ball valves have virtually no flow resistance.
2. Estrutura simples, tamanho pequeno, e peso leve.
3. Apertado e confiável. It has two sealing surfaces, and currently, various plastics are widely used as sealing materials for ball valves, resulting in good sealing performance and achieving a complete seal. It is also widely used in vacuum systems.
4. Easy operation and rapid opening and closing: Only a 90° rotation is needed to go from fully open to fully closed, facilitando o controle remoto.
5. Fácil manutenção: The ball valve has a simple structure, e os anéis de vedação são geralmente móveis, tornando a desmontagem e substituição conveniente.
6. Quando totalmente aberto ou totalmente fechado, as superfícies de vedação da esfera e da sede estão isoladas do meio, evitando a erosão das superfícies de vedação da válvula durante o fluxo médio.
7. Ampla gama de aplicações: Suitable for diameters ranging from a few millimeters to several meters, and for applications from high vacuum to high pressure.
Q61N High Pressure Welding Ball Valve Main Features
1. All components of this product are forged.
2. A bottom-mounted valve stem with a reverse sealing structure ensures reliable sealing at the packing and prevents the valve stem from detaching.
3. An embedded valve seat is used. An O-ring is installed on the back of the valve seat to ensure no media leakage.
