(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...

1. Surface condition of sealing surface The shape and surface roughness of the valve sealing surface have a certain impact on sealing performance, and a smooth surface is beneficial for sealing. Soft gaskets are prone to deformation and are not sensitive to surface conditions. For hard gaskets, the surface condition has a significant impact. 2. Contact width of sealing surface The larger the conta...

Just as sound can have a negative impact on the human body, certain frequencies can also cause serious damage to industrial equipment. High noise levels usually cause vibration and may damage equipment such as pipelines and instruments. With the passage of time, valve components deteriorate, and the cavitation generated by the valve is prone to serious damage. This type of damage is mostly caused ...

In steam and condensate systems, garbage and debris in pipelines often cause damage to equipment, such as scale, rust, welding slag, and other solid particles, which may enter the pipeline system. Strainers can filter out solid particles in liquids or gases, not only protecting equipment from damage, but also reducing equipment downtime and maintenance time. Strainers are generally installed upstr...
