The working principle of the forged steel ball valve is to make the valve unblocked or blocked by rotating the valve stem. The ball valve is easy to switch, small in size, can be made into a large diameter, reliable in sealing, simple in structure, convenient in maintenance, and the sealing surface and spherical surface are often in a closed state, which is not easy to be eroded by the medium, and...

Overview Ultra-low temperature butterfly valves are mainly used in pipeline systems of liquefied natural gas and liquid nitrogen to control the opening and closing or adjustment of the pipeline equipment. The product adopts a double offset structure and an elastic metal sealing structure. The double offset structure can greatly eliminate unnecessary overloading and scraping of the disc and sealing...

Working principle of globe valves Assuming there is a water supply pipeline with a cover, water is injected from the bottom of the pipeline and discharged towards the direction of the pipe mouth, and the cover of the outlet pipe mouth is equivalent to the closing part of the globe valve. If you lift the pipe cover up with your hand, the water will be discharged outward. If you cover the pipe cover...

(1) Selection principle of valves for water supply pipelines 1. When the diameter of the pipeline is less than 50mm, a globe valve should be used; When the pipeline diameter is greater than 50mm, gate or butterfly valves should be used; 2. When it is necessary to adjust the flow and water pressure, regulating valves and globe valves should be used; 3. For parts with low water flow resistance (such...

304 austenitic stainless steel (new standard 06Cr19Ni10 steel, old standard 0Cr18Ni9 steel) is widely used in industries such as petrochemical, metallurgical machinery, aerospace, food processing, instruments, household appliances, and hardware manufacturing due to its good toughness, plasticity, weld-ability, corrosion resistance, and non-magnetism at room and low temperatures. The reason why 304...

There are many types of structures for ball valves, mainly composed of valve seats, balls, sealing rings, valve stems, and other driving devices. It is used on pipelines to shut off, distribute, adjust flow rates, and change the flow direction of the medium. O-type Ball Valves The body of the O-ring ball valve is equipped with a ball with an intermediate through hole inside, and there is a through...
