Self powered typePressure control valve

Product introduction

Self-operated temperature control valve does not require external energy to automatically adjust the temperature. The self-operated temperature control valve realizes automatic adjustment by using the principle of liquid expansion under heat and liquid incompressibility. Widely used in heating, air conditioning, domestic hot water temperature automatic regulation.

Product characteristics

Compact structure, light weight, sensitive action, good sealing performance, stable working performance.

Self-operated pressure regulating valve is an automatic control valve that does not require external power supply. It relies on the pressure changes of the controlled medium to control the opening and closing of the valve, thus achieving pressure regulation. This valve is widely used in industries such as petroleum, chemical, power, and heating for automatic control systems, with advantages of simple structure, reliable operation, energy saving, and environmental protection. This article will provide a detailed introduction to the working principle, parameter selection, and applications of self-operated pressure regulating valves.

I. Working Principle of Self-operated Pressure Regulating Valve

Self-operated pressure regulating valve is mainly composed of valve body, valve seat, valve disc, spring, and adjusting screw. When the controlled medium enters the valve, the medium pressure acts on the valve disc, overcoming the pre-tension force of the spring, causing the valve disc to move away from the valve seat and open the valve. As the medium pressure increases, the valve disc gradually opens, allowing more medium flow. Conversely, when the medium pressure decreases, the valve disc closes the valve under the action of the spring, reducing the medium flow. By adjusting the screw, the pre-tension force of the spring can be changed to adjust the valve opening, ultimately achieving the goal of controlling the medium pressure.

II. Parameter Selection of Self-operated Pressure Regulating Valve

In the parameter selection of self-operated pressure regulating valve, the following main factors need to be considered:

Valve Size: The valve size should be determined based on the pipe size and required flow rate. When selecting the valve size, ensure that it matches the pipe size to avoid being too large or too small, which may affect the normal operation of the valve.

Spring Range: The spring range refers to the adjustment range of the spring pre-tension force. When selecting the spring range, it should be based on actual needs to ensure that the valve operates normally within the required pressure range.

Operating Pressure and Temperature: Operating pressure and temperature are important parameters for selecting self-operated pressure regulating valves. When selecting, consider the maximum working pressure and temperature of the medium to ensure that the valve can withstand pressure and temperature fluctuations.

Medium Characteristics: Medium characteristics include the corrosiveness, viscosity, impurity content of the medium, etc. When selecting self-operated pressure regulating valves, consider the characteristics of the medium, choose suitable valve materials and structures to ensure the valve's service life and reliability.

Additional Functions: According to actual needs, self-operated pressure regulating valves can choose some additional functions such as explosion-proof, corrosion-resistant, and insulation. These additional functions can improve the safety and performance of the valve.

III. Applications of Self-operated Pressure Regulating Valve

Self-operated pressure regulating valves are widely used in various industrial automation control systems, especially in high-pressure, high-temperature, and corrosive medium environments. Here are some typical application cases:

Heating System: In heating systems, self-operated pressure regulating valves can be used to control the pressure of hot water or steam, ensuring the stable operation of the heating system.

Petrochemical Industry: In the petrochemical industry, self-operated pressure regulating valves can be used to control the pressure and flow of the medium in pipelines, ensuring the stability and safety of the production process.

Power Industry: In the power industry, self-operated pressure regulating valves can be used to control the pressure and flow of boilers and turbines, ensuring the efficiency and safety of the power generation process.

Wastewater Treatment: In wastewater treatment processes, self-operated pressure regulating valves can be used to control the outlet pressure of water pumps, ensuring the quality and quantity of the effluent.

Pharmaceutical Industry: In the pharmaceutical industry, self-operated pressure regulating valves can be used to control the pressure and flow of the medium in pipelines, ensuring the production quality and safety of drugs.

In conclusion, as an efficient and reliable automatic control valve, self-operated pressure regulating valves have been widely used in various industries. Understanding its working principle, parameter selection, and application cases can help better select and use the valve, improving the performance and reliability of industrial automation control systems.
