双阀组截止阀

双阀组截止阀（Double Block Bleed Valve，简称DBB阀）是一种集成两个独立截止阀和一个排放阀（或泄放阀）的阀门组合装置，主要用于管道系统的安全隔离、介质排放及压力检测。该阀门组通常由两个串联的截止阀和一个位于中间的排放阀组成，确保在关闭状态下能够完全切断介质流动，并通过排放阀释放阀腔内的残余压力或介质，提高操作安全性。

双阀组截止阀主要特点

双重密封保障：两个独立的截止阀提供双重隔离，确保零泄漏。

安全泄放功能：中间排放阀可排出阀腔内残留介质，便于维护和检测。

结构紧凑：一体化设计，减少安装空间，提高系统集成度。

高耐压性：适用于高压工况，符合API、ASME标准。

多种连接方式：可采用法兰、螺纹或焊接连接，适应不同管道需求。

双阀组截止阀应用领域

石油化工：用于油气管道的安全隔离与排放。

天然气输送：确保管道维修时的介质切断与泄压。

电力行业：锅炉系统、蒸汽管道的安全控制。

工业流程：适用于需要双重隔离的高危介质输送系统。

Double Block Bleed (DBB) Valve Product Overview

The Double Block Bleed (DBB) Valve is an integrated valve assembly consisting of two independent shut-off valves a bleed ( vent) valve, primarily used for safe isolation, medium discharge, pressure testing in pipeline systems. This valve set typically includes two globe valves in series with a bleed valve in between, ensuring complete medium shut-off when closed allowing residual pressure medium to be released through the bleed valve for enhanced operational safety.

Key Features

Dual Sealing Protection: Two independent shut-off valves provide double isolation, ensuring zero leakage.

Safe Bleeding Function: The intermediate bleed valve releases residual medium the valve cavity for maintenance testing.

Compact Structure: Integrated design reduces installation space improves system efficiency.

High Pressure Resistance: Suitable for high-pressure applications, compliant with API, ASME, other international standards.

Multiple Connection Types: Available in flanged, threaded, welded connections to meet different pipeline requirements.

Applications

Petrochemical Industry: Used for safe isolation discharge in oil gas pipelines.

Natural Gas Transmission: Ensures medium shut-off pressure relief during pipeline maintenance.

Power Industry: Applied in boiler systems steam pipeline safety control.

Industrial Processes: Suitable for high-risk medium transportation systems requiring dual isolation
