1.603100 Commercial Space Concept
Chuanyi Corporation (603100) added the concept of "commercial space" on March 14, 2025, which is closely related to the successful guarantee of the first mission of the Hainan Commercial Space Launch Site No.1 Launch Station.
1. Product Application Support: Multiple products independently developed by Chuanyi Corporation played a key role in the commercial space launch.
. PDS intelligent pressure transmitter: used for accurate pressure monitoring of fuel injection pipelines, with an accuracy of 0.04% FS and a maximum of 0.025% FS, ensuring precise and error free pressure control during rocket fuel injection process. Ultra low temperature butterfly valve: maintains zero leakage sealing performance in liquid nitrogen environment at -196 ℃, providing key guarantee for rocket fuel ultra-low temperature delivery system and avoiding leakage risks caused by low temperature. DFPH series porous orifice flowmeter: It can accurately measure the flow data of hydrogen oxygen turbopump in the harsh environment of high temperature, high salt, and high humidity in coastal launch sites, ensuring stable fuel supply for rocket engines. High pressure resistant and high-precision temperature instrument: It continuously withstands high-pressure impacts in the rocket launch gas injection system, providing precise temperature monitoring state blind cavity to ensure the safety and reliability of the launch process.Secondly, a professional service team ensures customer needs. Chuanyi Corporation not only provides high-performance products, but also has a professional service team that can respond to customer needs in a timely manner and provide comprehensive technical support and serv
Third, the accumulation of honors in the aerospace field is not the first time that Chuanyi Corporation has accumulated technical skills in the aerospace field.
. In 2005, the company was awarded the title of "Contribution Enterprise to the Shenzhou VI Manned Technology Space Flight Mission and Launch Vehicle Development" by China Aerospace Science and Technology Corporation for overcoming the manufacturing difficulties of carrier rocket components for manned spacecraft, reflecting its technical strength and long-term contributions in the aerospace field. The addition of the concept of "commercial aerospace" marks a further expansion of Chuanyi Corporation in the field of commercial aerospace, and its products and services are expected to play a greater role in future commercial aerospace launch missions.2. The difference between orifice flowmeter and balance flowmeter
Both orifice flowmeter and balance flowmeter belong to differential pressure flowmeter, and their core differences cover four dimensions: principle, structure, performance, and installation. Balance flowmeter has stronger comprehensive adaptability, but orifice flowmeter has lower cost and simpler structure.
. 1. Principle difference: Both are based on differential pressure measurement logic that generates pressure difference through fluid throttling, relying on Bernoulli equation to calculate flow rate: the orifice flowmeter relies on a single thin plate with a central circular hole to achieve throttling, and a pressure difference is formed on both sides when the fluid flows through the orifice plate; The balanced flow meter adopts a porous symmetrical throttling struct
