  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 type, valve body material, and other related factors. At first glance, it may seem cumbersome, but the process can be understood as four simple steps: 1: Determine the drainage requirements required for the operation of the drain valve (such as hot or subcooled discharge) and determine the type of drain valve . 2: Select the valve model based on pressure, temperature, installation direction, and other factors. 3: Calculate the condensation water amount of the process load and multiply it by the manufacturer's recommended safety factor. 4: Select the most suitable drain valve based on t

  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 arranged and marked according to the PID instructions. 3. Valves on the bottom pipelines of equipment such as towers, reactors, and vertical vessels should not be arranged within the cluster. 4. Manual ball valves that need to be operated according to the instructions of the local instrument should be located close to the local instrument. 5. The regulating valve and safety valve should be arranged on the ground or platform in a place convenient for maintenance and debugging. 6. Fire hydrants or valves for fire protection should be located in a location that can be safely accessed in the ev

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 erosion, medium cavitation, various corrosion, blockage of impurities, improper selection of valve core and seat materials, deformation of the sealing pair caused by heat treatment process and water hammer, etc. 1. Electrochemical erosion. Due to factors such as mutual contact between sealing surfaces, contact between sealing surfaces and the sealing body and valve body, as well as differences in medium concentration and oxygen concentration, potential differences can occur, leading to electrochemical erosion and erosion of the sealing surface on the anode side. 2. Erosion and cavitation of the m
