Принцип работы


Концепция противосмесительного клапана Unique основана на ряде базовых деталей, включая корпус клапана, затвор клапана, привод и опции мойки, а также принадлежности, которые поддерживают широкий спектр применений. Используя эти компоненты, вы можете создать противосмесительный клапан Unique, в точности удовлетворяющий предъявляемым вами требованиям к процессу.

Для упрощения технического обслуживания противосмесительный клапан Unique оснащен отверстиями для обнаружения утечек, за счет чего обеспечивается предварительное уведомление об износе или повреждении неподвижных уплотнительных колец. Операторы могут проводить визуальный осмотр клапана в любое время без его разборки.

Принцип работы

Противосмесительный клапан Unique Альфа Лаваль представляет собой нормально закрытый (НЗ) клапан, который управляется дистанционно с помощью сжатого воздуха.

Для разделения двух жидкостей клапан имеет два независимых уплотнения затвора. Пространство между двумя уплотнениями образует атмосферную камеру утечки. В редком случае непреднамеренной утечки продукта он поступает в камеру утечки и выпускается через слив утечки.

Когда клапан открыт, камера утечки закрыта. В этом случае продукт может перетекать с одной линии на другую без разливов. Клапан можно легко очистить и защитить от воздействия гидроударов в соответствии с конкретными требованиями к процессу и конфигурацией клапана. (Во время работы клапана разлив продукта отсутствует).

State-of-the-art horizontal mixproof valve

Based on the well proven and exceptionally versatile principle of the Unique Mixproof valves, this horizontal mixproof tank valve features many of the same components, such as the actuator, yoke and seals, and therefore the same spare parts. This provides the benefits of easy serviceability and low total cost of ownership.

Alfa Laval Unique Mixproof Horizontal Tank Valve, can be fitted with any level of sensing and control. It is as standard supplied with seat lift, which enables handling of two different products at the same time, or safe handling of one product while seat-lift cleaning operations are being conducted in the other portion of the valve – all without any risk of cross-contamination. The double tangential design of the valve body ensures full drainability, especially when the valve is mounted at the bottom of a flat-bottomed tank.
