Precision Quantitative Valve: a precise tool for industrial control

In the field of precision control of modern industrial production, Precision Quantitative Valve, as a key equipment, has become an indispensable part of many production lines with its excellent quantitative accuracy and stable performance. This article will explain the structure, working principle, features and important role of Precision Quantitative Valve in industrial control.

Structure of Precision Quantitative Valve

精密定量バルブ is usually composed of major components such as valve body, valve disk (or piston), valve seat, driving device and measuring body. As the main body of the entire valve, the valve body supports the internal components and ensures smooth fluid flow. The valve head is precisely machined to form a tight seal with the valve seat, effectively preventing the passage of fluid when closed. The actuator is responsible for controlling the degree of opening and closing of the poppet, and is usually powered by an electric motor, pneumatic device, or hydraulic device to achieve precise control of fluid flow.

Operating Principle

The operating principle of the Precision Quantitative Valve is based on the volumetric metering principle. By controlling the travel and speed of the valve disk (or piston) in the valve body, the fluid flow can be precisely adjusted. When the actuator is started, the valve disk (or piston) leaves the valve seat under the effect of force and moves according to the preset stroke and speed. As the disc (or piston) moves, the fluid is allowed to pass through the valve at a certain rate, thereby achieving a quantitative fluid output. When the preset flow rate is reached, the actuator stops and the poppet (or piston) returns to the closed position to complete a quantitative process.

Features & Benefits

Accurate quantitative measurement: The use of high-precision processing and advanced control technology can ensure that the amount of fluid output each time reaches extremely high accuracy, meeting the needs of precise control of fluid flow in industrial production.

Convenient adjustment: By adjusting the control parameters of the driving device, the travel distance and speed of the valve disk (or piston) can be easily changed, thus achieving flexible adjustment of the fluid flow.

Simple control: The control system is usually simple, easy to operate and maintain, which reduces the cost of operation and the difficulty of maintenance.

Stable performance: Made of high-quality materials and precision processing technology, it has a long service life and stable performance, and can maintain normal operation in harsh industrial environments.

Plays an important role in industrial control

In industrial production, it is widely used in cases where precise control of fluid flow is required. For example, in the chemical production process, it is necessary to accurately control the ratio of various raw materials and reaction conditions to ensure product quality and production efficiency. At present, it is possible to ensure the accurate addition of raw materials and precise control of reaction conditions, providing strong guarantees for the smooth progress of chemical production. In addition, in the pharmaceutical, food, electronics and other industries, precision metering valves also play an important role in protecting the quality and safety of products.

In summary, with their excellent quantitative accuracy and stable performance, precision metering valves have become indispensable and important equipment in modern industrial production. With the continuous development and progress of industrial technology, the application scope of precision metering valves will continue to expand, providing strong support for production control in more and more fields.
