â‘ Hardness:
Due to the scientific synthesis of high-molecular polyurethane elastomer materials using iron rubber, the higher the hardness, the higher the modulus, the smaller the elongation, and the better the wear resistance and heat resistance. Well, in the range of minus 35 degrees Celsius to 100 degrees Celsius, and at a pressure of 60 to 70 MPa, the maximum sealing performance can be guaranteed.
The use of viscoelastic seals made of nitrile rubber is the most complete protection against damage caused by back pressure. In the range of minus 55 degrees Celsius to 100 degrees Celsius, and under a pressure of 21MPa, due to the rubber The seal is often in a compressed state, so the compression performance of the rubber seal must be considered. It not only achieves enhanced anti-climbing performance and low friction resistance, but also has good performance in dealing with special low-temperature oil, and can also be used in combination with Anti-wear Ring double-purpose retaining ring BRL type.
Sealing products made of polytetrafluoroethylene and nitrile rubber/PTFErubber; or seals made of nylon resin and nitrile rubber, which can be used in a wide range of applications with large pressure changes and fast sliding speeds According to the working condition, the input hydraulic pressure cutout is designed on the end face of the polytetrafluoroethylene ring to prevent penetration leakage. The maximum working temperature environment is minus 40 degrees Celsius to 160 degrees Celsius; the maximum working pressure is 50MPa.

Piston main oil seal
Water seal valve for working pressure 1.6 ~ 10.0MPa, operating temperature 0 ~ 425 ℃ thermal power plant backwater condensing system and oil, chemical and atmospheric requirements of the pipeline to cut off or connect the media, the applicable medium: water, oil Products, steam and non-corrosive gases. First, the characteristics and uses 1, S / Z series of opening and closing flexible, rapid, reliable seal, usually with double gate elastic seal; 2, the product structure is simple, compact and reasonable, easy maintenance, long service life; 3, The opening and closing device for the pipeline must be in the fully open or fully closed state and can not be used for regulating the flow rate. 4. There are two ways of connecting the valve: flange and welding. The driving mode is manual and electric, and the structure is complicated. Valve sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate valve single gate type, double gate type and elastic gate type. Parallel gate-type gate valve can be divided into single gate and double gate type. According to the thread position of the stem division, can be divided into Ming rod valve and dark rod gate valve two.
