Information
Liaoyang Valve Valve is a control component in the pipeline fluid conveying system. It is used to change the section of the passage and the flow direction of the medium. It has the functions of diversion, cut-off, throttling, check, diversion or overflow pressure relief. Valves used for fluid control, from the simplest shut-off valve to the various valves used in extremely complex automatic control systems, have a wide range of varieties and specifications. The nominal diameter of the valve ranges from extremely small instrument valves to large diameters up to 10m. Valves for industrial pipelines. It can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids. The working pressure of the valve can be from 0.0013MPa to 1000MPa ultra-high pressure, and the working temperature can be c-270℃ ultra-low temperature to 1430℃ high temperature.
The valve can be controlled by a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, pneumatic-hydraulic, spur gear, bevel gear drive, etc.; it can be driven by pressure and temperature. Under the action of other forms of sensing signals, it will act according to the predetermined requirements, or simply open or close without relying on the sensing signals. The valve relies on the drive or automatic mechanism to make the opening and closing parts lift, slide, swing or rotate Movement, thereby changing the size of the flow channel area to achieve its control function.
The cleaned parts must be sealed and stored for installation.
The requirements for the installation process are as follows:
1. The installation workshop must be clean, or set up a temporary clean area, such as newly purchased color striped cloth or plastic film, to prevent dust from entering during the installation process.
2. Assemblers must wear clean cotton overalls, cotton caps, no leakage of hair, clean shoes on feet, plastic gloves on hands, and degreasing.
3. The assembly tools must be degreased and cleaned before assembly to ensure cleanliness.
Since the valve has a wide range of uses, it also plays a great role. For example, in power plants, valves can control the operation of boilers and steam turbines; in petroleum and chemical production, valves also control the normal operation of all production equipment and technological processes. The same is true in other departments. Nevertheless, the comparison of valves with other products is often overlooked. For example: When installing machinery and equipment, people tend to focus on the main machinery and equipment, but ignore the valve. This will reduce the overall production efficiency or stop production, or cause various other accidents. Therefore, serious and responsible work must be carried out on the selection, installation and use of valves.
Electric drive valve is a commonly used drive type valve. The drive device of this type of drive device is usually called the valve electric device. The characteristics of the valve electric device are as follows: 1) Open and close quickly, which can greatly shorten the time required to open and close the valve; 2) It can greatly reduce the labor intensity of the operator, especially suitable for high-pressure, large-diameter valves; 3) Suitable for installation in locations that cannot be manually operated or difficult to access, easy to achieve remote control, and the installation height is not limited; 4 ) Conducive to the automation of the entire system; 5) Power is easier to obtain than air and liquid sources, and the laying and maintenance of its wires are much simpler than compressed air and hydraulic pipelines.
