Solenoid Valve Overview
The development of solenoid valves has evolved significantly over time, both domestically and internationally. Based on their operating principles, solenoid valves are generally categorized into three main types: direct-acting, pilot-operated, and step-by-step pilot. In terms of structure and materials, they can be further divided into six subcategories: direct-acting diaphragm type, step-by-step gate type, leading diaphragm type, direct-acting piston type, step-by-step piston type, and pilot piston type.
When installing a solenoid valve, it's crucial to ensure that the arrow marked on the body aligns with the direction of the media flow. Avoid installing the valve in areas exposed to direct water dripping or splashing. The solenoid valve should be mounted vertically, with the coil facing upward. It is important to maintain a power supply voltage within 15% to 10% of the rated voltage for stable operation. Additionally, there should be no backpressure in the pipeline when the valve is installed. Before putting the valve into formal use, it should be powered several times to allow it to reach an appropriate operating temperature.
Prior to installation, the solenoid valve must be thoroughly cleaned, and the media being transported should be free of impurities. A pre-filter may be necessary to protect the valve from damage. In case of failure or cleaning, a bypass device should be installed to ensure continuous system operation.
Common models include:
- **ZQDF**: Small diameter, available in carbon steel, cast iron, and stainless steel.
- **ZCM**: Suitable for gas applications, small to medium diameter, made of carbon steel and stainless steel.
- **US-F**: Normally closed type, suitable for small and medium diameters, constructed from carbon steel.
- **SLDF**: Underwater model, available in small and medium sizes, made of carbon steel, cast iron, and stainless steel.
- **2W**: Used in medical equipment, available in small and standard sizes, made of carbon steel and stainless steel.
These valves are widely used across various industries, including industrial automation, water treatment, HVAC, and medical systems, due to their reliability and efficiency. Proper selection and maintenance are essential to ensure optimal performance and longevity.
Sintering Series
The grate is the main accessory on the sintering machine trolley. The function of the grate is to form a trough-shaped space with the trolley rail to accommodate and carry the ore. The part of the castor bar in contact with the mineral material is the upper surface, and the two ends of the upper part of the castor bar are stressed and play a supporting role. The bottom of the grate has two functions. The first is to fix the grate when it is turned over and unloaded, so that it cannot fall off; the second is to support the grate when the top of the grate is pressed, which can effectively prevent the grate. bending.
