Given the wide variety of steam traps and their varying operating characteristics. Therefore, users often encounter difficulties when selecting steam traps. How to choose the correct steam trap to smoothly discharge condensate from the steam pipeline has become a challenge. The key considerations for selecting a steam trap include temperature and pressure range, drainage capacity, industrial valve...

General Requirements 1. The industrial valve should be located in a place that is easy to operate, install, and maintain. The valves on rows of pipelines (such as those entering and exiting the device) should be centrally arranged to facilitate the installation of operating platforms and ladders. 2. Some valve positions have process operation requirements and locking requirements, and should be ar...

The sealing damage of the steam trap valve is the main cause of internal leakage of the valve. There are many reasons for valve sealing failure, among which the failure of the sealing pair composed of the valve core and valve seat is the main reason. There are many reasons that affect the damage of the valve sealing surface, including mechanical wear caused by incorrect selection, high-speed erosi...

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...

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 ...

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...

Metal valves can be said to be the most susceptible key component structure to corrosion failure in engineering equipment. Usually, the sealing surfaces, valve stems, diaphragms, small springs, and other valve components of metal valves are made of first-class materials. The valve body, valve cover, etc. are made of secondary or tertiary materials. Valves used for high-pressure, highly toxic, flam...

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...

(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...

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...
