Шаровые краны для водопровода – это тип запорной арматуры для применения в трубопроводных системах, где перекрытие потока воды происходит с помощью шарика с отверстием внутри. Благодаря своей простой конструкции и долговечности, шаровые краны очень популярны и широко применяются как в домах, так и на заводах. Купить шаровый кран можно в онлайн-магазине CIR-LOK.
Эта деталь работает просто. Поворачивая шарик внутри корпуса, можно открыть или закрыть трубу. Когда кран открыт, отверстие в шарике совпадает с направлением воды, и она течет свободно. Когда он закрыт, шарик полностью перекрывает трубу, не давая воде пройти.
Шаровые краны водопроводные классифицируются по следующим признакам:
- по типу соединения;
- по типу запорного элемента;
- по материалу корпуса.
По типу соединения они бывают:
- Резьбовые. Наиболее часто используются, применяются для подключения к трубопроводам с помощью резьбовых соединений.
- Фланцевые. Применяются для соединения с трубопроводами при помощи фланцевых соединений, применяются для трубопроводов с большим диаметром, работающих под высоким давлением.
- Приварные. Привариваются непосредственно к трубопроводу, обеспечивая герметичность и надежность соединения. Соединяются фитингами.
Разновидности по типу конструкции:
- Полнопроходные. У них отверстие в шаре такое же широкое, как и сама труба, поэтому вода течет почти без препятствий.
- Неполнопроходные. Отверстие в шаре меньше, чем труба. Это создает больше сопротивления потоку, но сами детали получаются меньше и дешевле.
- Трехходовые и четырехходовые. Используются для направления потока воды в разные стороны.
Классификация кранов шаровых регулирующих по материалу корпуса:
- Стальные. Имеют высокую прочность, применяются в разных промышленных приложениях. Не подвержены коррозии, подходят для агрессивных сред.
- Латунные. Применяются для транспортировки воды и обеспечения отопительных систем.
- Пластиковые. Имеют небольшую массу, не подвержены коррозии, применяются как для бытовых, так и для промышленных трубопроводов.
Запорный шаровый кран покупают, принимая во внимание:
- Тип рабочей среды. Определяет из чего сделана деталь и какие уплотнители применяются. Учитывают возможные показатели давления и температуры. Определяет размер трубы.
- Тип соединения. Определяет тип конструкции, которая будет соединена с трубной системой.
- Назначение крана. Определяет конструктивные особенности детали.
Применение шаровых кранов в промышленности
- Нефтегазовая отрасль. Шаровые краны необходимы для безопасной и надежной работы с нефтью и газом. Их используют в трубопроводах, резервуарах и насосах для управления потоком, перекрытия аварийных участков и проведения ремонта.
- Химическая промышленность. Для работы с агрессивными химическими веществами требуются специальные шаровые краны из нержавеющей стали, титана или других материалов, устойчивых к коррозии.
- Пищевая промышленность. Здесь шаровые краны используют в трубопроводах для транспортировки пищевых продуктов, чтобы обеспечить чистоту и соответствие санитарным нормам.
- Энергетика. Шаровые краны применяются для перекрытия потока рабочей среды в системах энергоснабжения, обеспечивая их надежную работу при высоких температурах и давлениях.
- Водоснабжение и водоотведение. В системах очистки и распределения воды шаровые краны используются для управления потоком, перекрытия отдельных участков для ремонта и обслуживания.
Такие запорные устройства отвечают за то, чтобы промышленные предприятия работали бесперебойно и безопасно. Правильный вентиль, соответствующий конкретным требованиям — залог эффективности эксплуатации.
Преимущества шарового крана
Шаровой вентиль устроен просто. В нем есть шарик с отверстием и ручка для управления. Шарик, как правило, металлический, и когда отверстие в нем совпадает с трубой, вода течет свободно. Чтобы закрыть кран, достаточно повернуть ручку на четверть оборота – шарик поворачивается и перекрывает поток воды. За счет простой конструкции и небольшого количества деталей, рассматриваемые детали очень надежные и редко ломаются.
Еще одно преимущество – это быстрота и легкость управления. Повернув ручку на 90 градусов, можно моментально открыть или закрыть кран. Это особенно важно, когда нужно быстро остановить поток воды, например, при протечке.
Плотность соединения и стойкость к изнашиванию – важные характеристики этой детали. Затвор, который прилегает к кольцам из фторопласта, практически полностью перекрывает поток. Это минимизирует риск потерь рабочей среды.
Долговечность – еще один плюс рассматриваемого вида деталей. Благодаря простоте конструкции и прочности материалов он может выдерживать значительные нагрузки и сохранять свою работоспособность весь срок эксплуатации.
Детали рассматриваемой категории очень универсальны и используются везде, где нужно контролировать поток жидкостей или газов – в промышленности, в жилищно-коммунальном хозяйстве, в системах водоснабжения, отопления и газоснабжения. Они могут работать с разными жидкостями и газами, такими как вода, газ, нефть, и выбор материалов и конструкции зависит от того, с чем они будут контактировать.
Обслуживание шаровых кранов несложное. Обычно достаточно регулярно проверять их на герметичность и проводить технический осмотр, чтобы они работали исправно.
Благодаря качественным материалам они устойчивы к коррозии. Особенно хорошо показывают себя краны из нержавеющей стали, которые подходят для работы с агрессивными веществами и служат долго.
