What is an electric valve? Electric valve parts are the pressure line of industrial automation and process control, with the advantages of stable performance, convenient installation, reliability and durability. The main electric valve products introduced by Xiaobian today hope to help users better application.

Application of electric valve
The electric valve has a simple structure, only a few parts, and saves material consumption; small size, light weight, small size, installation size, driving torque, pressure regulating valve, simple and fast, just need to rotate 90 ° to quickly start and close ; Further also has good flow regulation and shut-off sealing characteristics, medium and large diameter, low pressure application range, the effectiveness of the electric ball valve is the dominant situation. When the electric valve is in the fully open position, the thickness of the disc is only when the medium flows through the resistance of the body, so the pressure drop generated through the valve is small and it has good flow characteristics of the grip.

Electric valve housing seal and two metal seal types. For elastic sealing valves, seals can be installed on the body or peripheral plate to tip. Metal-sealed valves generally take over the valve’s life and have a long elastic seal, but it is difficult to achieve a complete seal. Metal seals can adapt to higher temperatures, elastic seals lack point temperature limit. It is important to select a complete valve size and type if a single grip is used as a requirement for a flow motor valve. The structural principle of the electric valve is especially suitable for the manufacture of large-diameter valves.

Electric valves are not only widely used in general industry, petroleum, natural gas, chemical industry, water treatment, etc., but also can be used in the cooling water system of thermal power plants. Commonly used electric ball valves have two types of clip-type electric ball valves and flanged electric ball valves. The electric stud wafer ball valve is used to connect between the two pipe flanges. The electric ball valve is a flanged valve with bolts on both ends of the flange on the pipe flange valve adapter. The strength performance of the valve refers to the pressure of the medium that the valve can sustain. Continuous pressure valves are mechanical products, so they must have sufficient strength and stiffness to ensure long-term use without causing cracking or deformation.

Function is line pressure element industrial automation process control, usually used for remote media channel and off (ON, OFF and media) control.

Features: Integrated structure, single-phase 24VDC power supply AC220V and DC power supply control operation; small size, light weight, reliable performance, simple matching, flow rate, etc.

The electric ball valve has the action of rotating 90 degrees. The cock body is a sphere with a circular through hole or channel passing through its axis. The ball valve in the pipeline is mainly used as an electric ball valve to cut off, distribute and change the flow direction of the medium. It only needs to be rotated 90 degrees and a small torque can be closed tightly. Ball valves are more suitable for on-off and shut-off valves, but recent developments have designed ball valves to throttle and control flow, such as V-shaped ball valves.

The main features of the electric ball valve are its compact structure, reliable sealing, simple structure and convenient maintenance. Working medium, but also suitable for medium with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., and are widely used in various industries. The electric ball valve body can be integral or combined.

Electric ball valve actuator is an indispensable driving control device for realizing electric ball valve program control, automatic control and remote control. Its movement process is controlled by stroke, torque, etc. Since the working characteristics and utilization of electric ball valve actuators depend on the type and characteristics of the ball valve, the correct selection of the ball valve actuator is essential to prevent overloading.

The output torque of the actuator is the main parameter for selecting an electric actuator, and the output torque of the actuator should be 1.2 to 1.5 times the maximum operating torque of the selected ball valve. Secondly, according to the different conditions of use of the ball valve, select the appropriate opening and closing speed, which can prevent the ball valve actuator from opening and closing too fast and causing water hammer.

Electric ball valve actuators have special requirements, that is, they must be able to limit the torque (axial force) and the angle of rotation. When the specification of the electric device is determined, its control torque is also determined. Generally run within a predetermined time, the motor will not be overloaded. However, overloading may occur if the following conditions occur: First, the power supply voltage is low, and the required torque cannot be obtained, so that the motor stops rotating; Caused continuous generation of excessive torque, causing the motor to stop rotating; third, intermittent use, the generated heat accumulation, exceeded the allowable temperature rise of the motor; The fifth is that the ambient temperature is too high, which relatively reduces the thermal capacity of the motor.

1. The ambient temperature should be controlled within -25℃-70℃.

2. The explosion-proof electric ball valve should be selected in several situations, such as unstable current, environmental corrosion, flammable and explosive occasions, special media, and no maintenance for a long time.

3. Due to the complexity of the electric mechanism, it should not be disassembled by itself when a fault occurs to prevent accidents.

4. Do not knock the electric ball valve or put items together under any circumstances.
