AIR LOGIC孔板限流器介绍及选型（中英文）

节流孔用于控制各种系统中气体、空气和液体的流动，从通风机到咖啡机，无所不包。节流孔有多种直径、材质和配置可供选择，以满足各种液体和气流控制应用的特定需求。

Orifices control the flow of gas, air, and liquid through a variety of systems, from Ventilators to Coffee Makers. They are available in a wide range of diameters, materials, and configurations to meet the particular needs of various liquid and airflow control applications.

什么是节流孔？为什么要使用它们？

What are Orifices and Why Use Them?

节流孔，也称为流量限制器或孔口节流器，或固定体积流量控制器，用于控制流经系统的气体或流体流量。这些装置的直径可使其在安装的系统中保持恒定的流量。节流孔的位置和尺寸决定了其具体用途，但它们最常用于限制物料流量以及监测和控制从航空航天到医疗等行业的流量。

Orifices, also known as flow restrictors or orifice restrictors, or fixed volumetric flow control, control the flow of gases or fluids through a system. The diameter of these devices maintains a constant flow rate through the system in which it is installed. The placement and size of an orifice determine its particular use, but they are most commonly used to restrict material flow and monitor and control flow rates in industries ranging from aerospace to medical.

流量控制的重要性

The Importance of Flow Control

流量控制对于各行各业工业和制造设备的安全高效运行至关重要。气动和液压系统尤其需要使用节流孔来确保最佳的压力控制和流量，而无需手动调节和重新校准。通过确定节流孔的正确直径和形状，可以精确地监测和控制系统流量，并计量流量添加剂，以确保输出的一致性、精确性和可预测性。

Flow control is critical for the safe and efficient operation of industrial and manufacturing equipment in various industries. Pneumatic and hydraulic systems in particular use orifices to ensure optimal pressure control and flow without the need for manual regulation and recalibration. By determining the correct diameter and shape of your orifice, they can carefully monitor and control system flow rates and gauge flow stream additives to ensure outputs are consistent, precise, and predictable.

Air Logic 提供全面的节流孔产品组合，包括模压节流孔、过滤节流孔和螺纹节流孔，以及多种方向流量控制阀。

Our comprehensive portfolio of orifices includes molded, filtered, and threaded orifices, as well as a selection of directional flow control valves.

模压节流孔

Molded Orifices

作为 Air Logic 最受欢迎的设计，模压节流孔提供了简单的流量控制方法。每个节流孔都易于识别，并采用颜色编码的直径尺寸，以实现最佳的流量限制。模压节流孔在美国精密成型、组装和测试。它们采用聚砜、聚丙烯和聚碳酸酯材质制成，并可根据特定应用需求进行定制。

As Air Logic’s most popular design, molded orifices offer the simplest method of flow control. Each orifice is easily identifiable, with color-coded diameter sizes for optimal flow restriction. Our molded orifices are precision molded, assembled, and tested in the US. They are available in polysulfone, polypropylene, and polycarbonate materials, and can be customized to meet your particular application requirements.

过滤节流孔

Filtered Orifices

过滤节流孔将集成过滤器与精密模制节流孔相结合，以减少各种应用中的上游污染。过滤节流孔由聚砜外壳和节流孔组成，并配有不锈钢网状过滤器，并提供多种定制选项。

The filtered orifices incorporate an integrated filter into precision-molded orifices to reduce upstream contamination in a variety of applications. Our filtered orifices are comprised of polysulfone Housing and orifice with a Stainless Steel Mesh filter with a variety of customization options.

螺纹节流孔

Threaded Orifices

为了便于安装，Air Logic 的螺纹节流孔在业内首屈一指。它配有内置螺纹接头，可直接将节流孔安装到管道中，实现简单安全的流量控制。螺纹节流孔采用聚砜材质，可根据需求定制。

For ease of installation, Air Logic’s threaded orifices are second to none in the industry. With an incorporated threaded fitting, you can install the orifice directly into the pipeline for a simple and secure flow control method. Our threaded orifices are available in polysulfone materials and can be customized to your needs.

Directional Flow Controls

方向流量控制器

方向流量控制器采用节流孔技术，控制一个方向的流量，并在相反方向提供全流量。节流孔是物料流动的唯一路径。方向流量控制器会根据流向自动移动。在一个方向上，流体会将阀瓣推至不受限制的位置。在相反方向上，阀瓣会移动并迫使流体通过节流孔。向流量节流孔有尼龙、聚砜、硅胶和不锈钢材质可供选择。

Directional flow control valves use orifice technology to control flow in one direction and provide full flow in the opposite direction. The orifice acts as the only path for material flow. The directional flow controls automatically move depending on the direction of the flow. In one direction, the flow will push the disk into an unrestricted position. In the opposite direction, the disk will move and force the flow through an orifice. Our directional flow orifices are available in nylon, polysulfone, silicone, and stainless steel.

材质选择

Material Selection

选择最适合应用的材质至关重要。由于节流孔安装在许多不同的应用中，因此化学兼容性和耐温性至关重要。因此，Air Logic 通常使用聚砜或聚丙烯聚合物。

聚砜和聚丙烯都因其耐化学性和在压力和高温下的稳定性而备受推崇。它们不会氧化或生锈，因此特别适用于气动设备。凭借耐化学性，聚砜和聚丙烯节流孔比其他材质更耐用、使用寿命更长。更少的磨损和腐蚀意味着更少的零件更换和设备故障，从而大大降低了维护和维修成本。

It is important to consider which material is best for your application. Since orifices are installed in many different applications, chemical compatibility and temperature resistance are critical. For this reason, Air Logic typically uses polysulfone or polypropylene polymers.

Both polysulfone and polypropylene are valued for their chemical resistance and exceptional stability under pressure and high temperatures. They do not oxidize or rust, which makes them especially useful for pneumatic equipment. With exceptional chemical resistance, polysulfone and polypropylene orifices are more durable and longer-lasting than other materials. Less wear and corrosion means fewer part replacements and equipment failures, which greatly reduces your maintenance and repair costs.

定制节流孔尺寸
