Spool with high-performance specialty plastics polyether ether ketone resin (PEEK) Manufacturing

In recent years, has become a research hotspot. General distribution of hydrothermal vents on the seafloor volcanic activity active regions, hydrothermal fluids with high  Check valve , high pressure, corrosion, etc., to the study of hydrothermal sampler brings a huge challenge. Deep-sea hydrothermal sampling required to maintain a constant pressure sample and the sample is not contaminated. sampler sampling valve is one of the key components of the system, the use of reliable  Instrument valve manifolds , the maximum working pressure of 70 MPa. according to anti-corrosion, high temperature and sealing requirements , TC4 titanium alloy valve body, valve using high-performance specialty plastics polyether ether ketone resin (PEEK) manufactured, it has a very high stiffness and hardness, as well as unique high tensile strength and fatigue strength, also has excellent high  Valve manifolds , thermal stability and corrosion resistance, continuous use temperature of 260 ℃, short-term temperature up to 300 ℃. trial found spool pressure differential generated by the axial load, due to the structure size unreasonable excessive stress can cause plastic deformation or fracture occurs, it is difficult to maintain pressure on the samples collected.
