Поворотные затворы are used to control the flow of fluids through a piping system. There are three main types of butterfly valves: resilient seated, высокая производительность, and triple offset. Here are the key differences between these three types:
Resilient Seated Butterfly Valves:
Resilient seated butterfly valves are the most common type of butterfly valve. They have a flexible rubber seat that provides a tight seal against the disc when the valve is closed. Resilient seated butterfly valves are generally used for low-pressure applications and are typically less expensive than high-performance and triple-offset butterfly valves.
Resilient Seated Butterfly Valves application
Resilient seated butterfly valves are commonly used in a variety of applications where low-pressure and moderate temperature fluid control is required. Some common applications for resilient seated butterfly valves include:
- Водоочистные сооружения: Resilient seated butterfly valves are often used in water treatment plants for regulating the flow of water and other fluids through various stages of the treatment process.
- системы отопления, вентиляции и кондиционирования: Resilient seated butterfly valves are used in heating, вентиляция, и кондиционер (ОВК) systems for regulating the flow of air and water through the system.
- Industrial applications: Resilient seated butterfly valves are used in many industrial applications, включая химическую обработку, еда и напитки, фармацевтический, and pulp and paper industries.
- Системы противопожарной защиты: Resilient seated butterfly valves are commonly used in fire protection systems for regulating the flow of water and other fire-fighting agents through sprinkler systems and fire hydrants.
В общем, resilient seated butterfly valves are suitable for applications that require a simple and cost-effective solution for controlling low-pressure fluid flow.
High-Performance Butterfly Valves:
Высокопроизводительные дроссельные заслонки have a metal seat and are designed for high-pressure applications. They have a tighter seal than resilient seated butterfly valves, which makes them ideal for applications where leakage cannot be tolerated. High-performance butterfly valves also have a higher temperature range than resilient seated butterfly valves.
High Performance application
High-performance butterfly valves are designed for use in applications where higher pressures, температура, and tighter shut-off requirements are necessary. Here are some common applications for high-performance butterfly valves:
- Oil and gas industry: High-performance butterfly valves are commonly used in the oil and gas industry for controlling the flow of various fluids, including crude oil, натуральный газ, and refined petroleum products. These valves are designed to withstand high pressures and temperatures and can operate reliably in harsh environments.
- Выработка энергии: High-performance butterfly valves are used in power generation plants to control the flow of steam, газ, and other fluids in turbines and boilers. These valves are designed to handle high temperatures and pressures and provide a tight seal to prevent leaks.
- Химическая обработка: High-performance butterfly valves are used in the chemical processing industry for regulating the flow of corrosive and hazardous fluids. These valves are made of materials that can withstand corrosion and can operate at high temperatures and pressures.
- Водоочистные сооружения: High-performance butterfly valves are also used in water treatment plants for regulating the flow of water and other fluids at high pressures and temperatures.
Общий, high-performance butterfly valves are suitable for applications that require a more robust and reliable solution for controlling fluid flow at high pressures and temperatures with a tighter shut-off requirement.
Дисковые затворы с тройным смещением:
Triple offset butterfly valves are designed for high-performance applications where tight shut-off is critical. They have a unique sealing mechanism that eliminates rubbing and wear between the seat and disc, which provides a tight seal even at high temperatures and pressures. Triple offset butterfly valves are typically more expensive than resilient seated and high-performance butterfly valves.
Triple Offset Butterfly Valves application
Triple offset butterfly valves are designed for use in critical applications where high performance, плотное отключение, and low leakage rates are essential. Here are some common applications for triple offset butterfly valves:
- Oil and gas industry: Triple offset butterfly valves are commonly used in the oil and gas industry for controlling the flow of various fluids, including crude oil, натуральный газ, and refined petroleum products. These valves are designed to provide a tight seal even at high pressures and temperatures, which makes them ideal for critical applications.
- Химическая обработка: Triple offset butterfly valves are used in the chemical processing industry for regulating the flow of corrosive and hazardous fluids. These valves are made of materials that can withstand corrosion and can operate at high temperatures and pressures with a tight shut-off.
- Выработка энергии: Triple offset butterfly valves are used in power generation plants to control the flow of steam, газ, and other fluids in turbines and boilers. These valves are designed to handle high temperatures and pressures and provide a tight seal to prevent leaks.
- Pulp and paper industry: Triple offset butterfly valves are used in the pulp and paper industry for controlling the flow of various chemicals and liquids used in the manufacturing process. These valves are designed to handle harsh chemicals and high temperatures with a tight shut-off.
Общий, triple offset butterfly valves are suitable for critical applications that require high performance, плотное отключение, and low leakage rates, especially in harsh environments where corrosive and hazardous fluids are being used.
