1. Non rising stem gate valve: The stem nut is located inside the valve body and in direct contact with the medium. When opening and closing the gate, rotate the valve stem to achieve this. The advantage of this structure is that the height of the gate valve remains constant, so the installation space is small, making it suitable for gate valves with large diameters or limited installation space. ...

Structurally Gate valves can rely on medium pressure to tightly close the sealing surface, thereby achieving the effect of no leakage. When opening and closing, the sealing surface of the valve core and valve seat always come into contact and rub against each other, so the sealing surface is prone to wear. When the gate valve is close, the pressure difference between the front and back of the pipe...

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...
