Classification of actuated valves
The main effect of the valve is to effectively control the flow of media in the pipeline system, its operation of the pipeline system and the stability of industrial engineering has an important role in industrial production is indispensable. Valves are usually connected to different power sources when in use, and can be categorized into hydraulic drive, pneumatic drive and electric drive according to the power supply. According to the actual situation of the pipeline, the application of these 3 kinds of valves is also different.
Hydraulic Actuated Valve
Hydraulically actuated valves are shown in pic.1. Hydraulic drive valve main control medium is mainly liquid-based, can well realize high torque transmission and control. Although the specific volume of the liquid medium is small, the hydraulic drive can still implement effective control. Hydraulic drive valves are large in size, so the installation must take into account the usage scenario, otherwise it may not be possible to install them.
Pneumatically Actuated Valves
Pneumatically actuated valves are shown in pic.2. Pneumatic actuated valve is a common type of valve in industrial production, and its working environment is air. The nature of air is relatively special, so the pneumatic valve can avoid accidents to a certain extent, but the production of compressed gas is not easy to realize.
Motorized Actuated Valves
Motorized actuated valves are shown in pic.3. In use motorized actuated valves can be operated by manual or automated techniques and are characterized by high efficiency and fast response time. Compared with the traditional hydraulic and pneumatic valves, electric valves have many advantages, specifically including five aspects.
(1) Integration of computerized work and introduction of new electronic technology saves time and labor.
(2) Motorized valves do not require a special compressed gas source or valve equipment, but traditional valves have more project investment in this regard.
(3) Even if the motorized valve power loss, can maintain the original mechanical position.
(4) Motorized valves can realize remote DCS control, while switching signal data transmission is basically no obstacle.
(5) compared with traditional valves, electric valves required cable laying is relatively simple, the system structure is not complex, the later cable pipeline inspection and maintenance is more convenient.
At the same time, due to the simplicity of the equipment structure, equipment failure rate is significantly lower than other types of valves.
