Smc solenoid valve driven by the coil can only be turned on or off, switching time is short.
The electric valve is usually driven by a motor. The opening or closing operation requires a certain amount of time for analog measurement and can be adjusted.
2. The nature of work:
Solenoid valves generally have a small flow coefficient and the working pressure difference is small. For example, the general 25-gauge solenoid valve has a much smaller flow coefficient than the 15-bore electric ball valve. Solenoid valves are driven by solenoids and are easily damaged by voltage surges. The equivalent of the switch is to open and close two roles.
The electric valve is usually driven by a motor and is relatively resistant to voltage shocks. Solenoid valves are quick-opening and fast-closing. They are generally used in small flow and small pressure, where the switching frequency is large, and the electric valve is reversed. The opening degree of the electric valve can be controlled, and the state is on, off, half-open and half-close, which can control the flow of medium in the pipeline and the solenoid valve can not meet this requirement.
Solenoid valve can be reset when the power is off. The electric valve needs such a function to add a reset device.
3 applicable process:
Solenoid valve is suitable for some special technical requirements, such as leakage, special fluid medium, etc., which is more expensive.
Electric valve is generally used for adjustment, but also the amount of switching, such as: fan coil end.
Solenoid valves act as an actuator for automated meters and their usage increases dramatically. This article analyzes the main characteristics of the solenoid valve, and focuses on the perspective of the application of the domestic development of mature technology, a brief summary of the refinement, intelligence, generalization, specialization direction was investigated and slightly impacted the development of electromagnetic valve technology Social factors are discussed.
First, the product selection points 1. Solenoid valve selection of the main control parameters for the path, the design of the nominal pressure, the medium allowable temperature range, interface size and so on.
2. The solenoid valve is used to open and close the valve by an electromagnet. It is usually used in two-position control with a bore diameter of 40mm or less, and is especially used to switch on, cut off, or change the gas and liquid lines.
3. The sealing performance of the valve is one of the main indicators to evaluate the quality of the valve. Valve sealing performance mainly includes two aspects, namely inner leakage and outer leakage. Endoleak refers to the degree of sealing achieved by the media between the seat and the closure. Outer leakage is the leakage of the valve stem packing, the leakage of the gasket in the middle port, and the leakage of the valve body due to casting defects. Leakage is not allowed to happen.
4. The main advantages of the solenoid valve are small size, reliable operation, convenient maintenance, and low price. When selecting, it is necessary to pay attention to selecting normally open or normally closed according to process requirements.
Second, SMC solenoid valve construction and installation points 1. SMC solenoid valve installation position, height must comply with the port direction design requirements, the connection should be firmly close.
2. Before the valve is installed, a visual inspection must be performed. The nameplate of the valve shall comply with the provisions of the current national standard GB12220 "General Valve Mark".
