Pneumatic Lined Fluorine Regulating Valve

Product introduction

Pneumatic fluorine-lined regulating valve is a kind of anti-corrosion straight single-seat regulating valve. The inner wall of the valve body and the inner components in contact with the fluid are lined with corrosion-resistant and age-resistant polyperfluorinated ethylene propylene (F46) by high pressure injection molding process, and polytetrafluoroethylene (F4) bellow pipe seal. Widely used in acid, alkali and other strong corrosive media and toxic, volatile gas, liquid control.

Product characteristics

Corrosion resistance, good sealing performance, small leakage, large output force, compact structure.

Pneumatic lined fluorine regulating valve is a common industrial automation control equipment, it regulates the gas pressure to control the flow, pressure and other parameters of the pipeline medium, widely used in chemical, petroleum, electric power, pharmaceutical and other fields. This paper will introduce the working principle, selection and application of pneumatic lined fluorine regulating valve in detail.

First, the working principle of pneumatic lined fluorine regulating valve

Pneumatic lined fluorine regulating valve is mainly composed of valve body, valve disc, pneumatic actuator and positioner. The inside of the valve body is lined with fluorine material, which can resist the erosion of various acid, alkali and salt and other strong corrosive media. The pneumatic actuator accepts the control signal from the control system, and drives the valve disc to switch or adjust the action in the valve body, so as to control the parameters of the medium flow rate and pressure in the pipeline.

The working principle of the pneumatic lined fluorine regulating valve is to control the position of the valve disc through the pneumatic actuator, and then change the flow rate of the pipeline medium. When the control system sends a control signal to the pneumatic actuator, the actuator will drive the valve disc to carry out the corresponding action in the valve body, so that the medium flow rate reaches the preset value. In the adjustment process, the role of the positioner is to convert the control signal output by the control system into the air pressure signal that can be identified by the pneumatic actuator, so as to accurately control the position of the valve disc, and realize the stable control of the flow rate and pressure parameters of the pipeline medium.

2. Selection and application of pneumatic lined fluorine regulating valve

When choosing a pneumatic fluorine-lined regulator, the following factors need to be considered:

1. Medium characteristics: understand the nature of the medium of the pipeline, including temperature, pressure, flow, corrosion, etc., in order to choose the appropriate pneumatic fluorine lined regulator. For highly corrosive media, it is necessary to choose a regulator valve with fluorine lined material inside to improve the corrosion resistance of the equipment.

2. Valve specifications: Select the appropriate specifications of the regulating valve according to the actual needs, including caliber, flow coefficient and other parameters. In the selection, it is necessary to consider the flow and pressure parameters of the pipeline medium to ensure that the regulator can meet the actual needs.

3. Control accuracy: According to the actual control accuracy requirements to select the appropriate positioner control valve. The function of the positioner is to convert the control signal into a pressure signal, so as to accurately control the position of the valve disc, and realize the stable control of the flow and pressure parameters of the pipeline medium. In the selection, it is necessary to consider the requirements of control accuracy and stability.

4. Valve drive mode: Choose the right valve drive mode according to the actual demand. Common valve driving methods are manual, electric, pneumatic and so on. For occasions where remote control or automatic control is required, electric or pneumatic drive should be selected. In the selection, you need to consider the installation location of the equipment, ease of operation and safety requirements.

5. Valve material: Select the right valve material according to actual needs. The material of pneumatic lined fluorine regulating valve includes cast steel, stainless steel and so on. For different use environments and requirements, the appropriate material should be selected to improve the durability and reliability of the equipment.

The pneumatic fluorine-lined regulating valve adopts the top guide structure and multi-spring actuator, which has the advantages of compact structure, light weight, sensitive action, fluid channel is streamlined S, small pressure drop loss, large valve capacity, accurate flow characteristics, convenient disassembly and so on. It is widely used to accurately control the process parameters of gas, liquid and other media to keep the pressure, flow rate, temperature and liquid level at the given value. It is especially suitable for occasions where the leakage is small and the pressure difference between the front and back of the valve is not large. This series of products have standard type, regulation cut type.
