Definition and Application of GOST Standard Cast Iron Gate Valve The GOST standard cast iron gate valve is a key equipment widely used in various working conditions such as oil, chemical, hydraulic, and thermal power stations. Its main function is to cut off or connect the medium, such as water, oil products, and steam. The design of this valve aims to provide good sealing performance and long service life, while ensuring the convenience and safety of operation. Application Scenarios Oil Industry: Used for the transportation of crude oil and refined oil. Chemical Industry: Suitable for the transmission and control of various chemical substances. Hydroelectric Power: Used to regulate water flow in hydropower stations. Thermal Power Station: Controls the flow of steam and hot water. Structural Characteristics of GOST Standard Cast Iron Gate Valve Main Structural Forms The GOST standard cast iron gate valve usually adopts a straight-through or right-angle structure, which makes the valve more convenient to install and maintain. Seal Face Material The seal face of the valve usually uses stainless steel and hard alloy, which not only improves the sealing performance but also greatly extends the service life of the valve. Operation Mode The GOST standard cast iron gate valve has a variety of operation modes, including manual, gear transmission, electric, and pneumatic, to meet the needs of different industrial occasions. Working Principle and Characteristics of GOST Standard Cast Iron Gate Valve Working Principle When the medium enters the valve from the bottom of the valve disc, the operating force needs to overcome the resistance, which is mainly the friction force between the valve stem and the packing and the pressure of the medium. Main Characteristics Simple structure: Easy to manufacture and maintain. Short working stroke: Short opening and closing time. Good sealing performance: Low friction force between the sealing surfaces and long service life. Standards and Specifications of GOST Standard Cast Iron Gate Valve The design and production of GOST standard cast iron gate valves follow a series of national and international standards, including but not limited to: GB/T12233-2006 “General Valves Iron Gate Valves and Lift Check Valves” GB/T12235-2007 “General Valves Flange Connected Steel Gate Valves and Lift Check Valves” JB/T53174-94 “Quality Grading of Gate Valve Products” JB/T53165-92 “High-pressure Balanced Gate Valve” These standards and specifications ensure the quality and performance of GOST standard cast iron gate valves, enabling them to meet the needs of different industrial applications. Market Supply of GOST Standard Cast Iron Gate Valve There are a variety of types of cast iron gate valves on the market, including German standard, national standard, and Russian standard, etc. For example, product information such as German standard Y-type filter, DIN filter, etc., can be obtained through specific suppliers. This shows that GOST standard cast iron gate valves have a wide range of supply and application in the world. In summary, the GOST standard cast iron gate valve, with its excellent performance, diverse specifications, and wide range of application scenarios, has become one of the indispensable important equipment in the industrial field.
