What are the characteristics of the types of throttling manifolds?
Throttle manifolds are widely used in industries such as petroleum, chemical, and metallurgy, with a variety of types and unique characteristics for each type. The following is a detailed explanation of the types and characteristics of throttling manifolds:
1、 Types of throttling manifolds
Manual throttling manifold:
Features: Both the commonly used and backup throttle valves in the manifold are manual throttle valves, which are easy to operate and do not require external power sources.
Application: Suitable for situations where flow control accuracy is not high but quick response is required.
Hydraulic throttling manifold:
Features: Both the commonly used and backup throttle valves in the manifold are hydraulic throttle valves, which can be remotely controlled and operated automatically through hydraulic or pneumatic drive.
Application: Suitable for occasions that require remote or automated control, such as large oil drilling platforms, chemical plants, etc.
Electric throttle manifold:
Features: The throttle valve is driven by an electric actuator, which has the advantages of fast response speed and high control accuracy.
Application: Suitable for situations where high precision flow control is required and remote monitoring and centralized management are needed.
Pneumatic throttling manifold:
Features: Powered by compressed air, the throttle valve is driven by a pneumatic actuator. The pneumatic throttling manifold has a simple structure and is easy to maintain.
Application: Suitable for flow control in special environments such as flammable and explosive, high temperature and high pressure.

2、 Common characteristics of throttling manifolds
Flow control: The throttle manifold controls the fluid flow by adjusting the opening of the throttle valve to meet different process requirements.
Simple structure: Throttle manifolds are usually composed of throttle valves, pipelines, pressure gauges, and other components, with a relatively simple structure that is easy to install and maintain.
Strong pressure bearing capacity: The pressure bearing parts of the throttling manifold are made of high-quality materials with good mechanical properties and can withstand high pressures.
Wide applicability: Throttle manifolds are suitable for various fluid media, including liquids, gases, and steam, and are widely used in fields such as petroleum, chemical, and metallurgy.
3、 Specific model and performance parameters
The specific model and performance parameters of the throttling manifold may vary depending on the manufacturer and application scenario. The common models of throttling manifolds include the QJX series, where QJX is the prefix for the throttling manifold model. The diameter of the throttle hole is one of the performance parameters that distinguish different models, and the smaller the diameter, the higher the control accuracy. In addition, the pressure rating of the throttling manifold is also one of the important performance parameters, with common pressure ratings including 35MPa, 70MPa, and 105MPa.
4、 Summary and Induction
