M364 三阀组

M364三阀组是一种与差压变送器配套使用的高集成度、一体化的仪表阀门组件。其核心功能是为差压测量系统提供过程压力引导、在线隔离、零点校验/迁移和排污泄放，是差压法测量流量、液位时不可或缺的关键附件。

M364三阀组将三个功能阀（两个隔离阀和一个平衡阀）精密地集成在一个共同的阀体上。其标准操作流程为：启动仪表时，先打开平衡阀，然后同时打开高低压隔离阀，后关闭平衡阀；停运仪表时，先打开平衡阀，然后同时关闭高低压隔离阀。此操作顺序能有效保护变送器的敏感膜盒免受单向过压冲击而损坏。

"M364"通常是制造商的特定型号，指代一种紧凑型、采用外螺纹（NPT等）连接的三阀组设计。其结构紧凑，安装方便，可直接安装在变送器接口上，极大减少了安装空间和潜在的泄漏点。

M364三阀组主要特点：

集成化设计： 将三个阀的功能集于一个阀体，结构紧凑，泄漏点少。

保护变送器： 内置平衡阀是保护差压变送器膜盒免受差压过载损坏的关键。

操作便捷： 提供标准的操作流程，便于进行在线零点校验和维护。

安装方便： 通常采用螺纹连接，可直接与变送器接口对接，节省安装空间和时间。

M364三阀组经济高： 减少了多个单独的阀门和管件，降低了总体成本和安装复杂度。

M364三阀组典型应用：

广泛应用于石油、化工、电力、冶金、造纸等行业，与差压变送器配套，用于测量管道内流体的流量、液位和密度，尤其适用于需要频繁校验或维护的场合。

M364 3-Valve Manifold Product Overview

The M364 3-Valve Manifold is a highly integrated, unitary instrumentation valve package designed for use with differential pressure (DP) transmitters. Its core functions are to provide process pressure guidance, in-line isolation, zero checking/migration, venting/draining for differential pressure measurement systems. It is an essential accessory for flow level measurement using the differential pressure method.

This manifold integrates three functional valves (two block valves one equalizing valve) precisely into a common body. The standard operating sequence is: To put the transmitter into service: open the equalizing valve first, then open both the high low pressure block valves simultaneously, finally close the equalizing valve. To take the transmitter out of service: open the equalizing valve first, then close both block valves simultaneously. This sequence effectively protects the transmitter's sensitive diaphragm damage due to unilateral overpressure.

"M364" is typically the manufacturer's specific model number, referring to a compact design of 3-valve manifold often with external threaded (e.g., NPT) connections. Its compact structure facilitates easy installation directly onto the transmitter's interface, significantly reducing required space potential leak points.

Key Features:

Integrated Design: Combines the function of three valves into one body, offering a compact structure fewer potential leak points.

Transmitter Protection: The built-in equalizing valve is key to protecting the DP transmitter's diaphragm damage caused by differential pressure overrange.

Operational Convenience: Provides a standardized operating procedure for easy in-line zero checking maintenance.

Easy Installation: Typically features threaded connections for direct mounting to the transmitter, saving installation space time.

Cost-Effective: Reduces the need for multiple individual valves fittings, lowering overall cost installation complexity.

典型应用 (Typical Applications):

Widely used in industries such as oil & gas, chemical, power generation, metallurgy, pulp & paper. It is paired with DP transmitters for measuring flow, level, density of fluids in pipelines, particularly in applications requiring frequent calibration maintenance.
