定義：
Y型密封圈的截面呈Y形，是一種典型的唇形密封圈。廣泛應用于往復動密封裝置中，其使用壽命高于O型密封圈。Y型密封圈的適用工作壓力不大于40MPa，工作溫度為-30～80℃。
分類：
Y型密封圈按照截面的長寬比例不同，可以分為寬型Y型密封圈、窄型Y型密封圈和Yx型密封圈等。寬截面的Y型密封圈的耐壓力略小于窄型Y型密封圈，只能適用于P<20MPa的工作環境，而窄型Y型密封圈可用于工作壓力P<32MPa的場合。
Y型密封圈按照兩唇的高度是否一致，又可以分為軸用的不等高唇Y型密封圈、孔用的不等高唇Y型密封圈和軸孔通用的等高唇Y型密封圈。Y型密封圈的制造材質不同，還能將其分為丁腈橡膠Y型密封圈、氟橡膠Y型密封圈、聚氨酯橡膠Y型密封圈等。
工作速度范圍：采用丁睛橡膠制作時為 0. 01～0. 6m/s；采用氟橡膠制作時，為0.05～0.3m/s；采用聚氨酯橡膠制作時，則為 0.01～lm/s。Y型密封圈的密封性能、使用壽命及不同擋圈時的工作壓力極限，都以聚氨酯橡膠材質為佳。
產品特點：

VITON氟素橡膠Y型圈——耐高溫性優于硅橡膠，有極佳的耐候性、耐臭氧性和耐化學性，耐寒性則不良。對于大部份油品及溶劑都具有抵抗能力，尤其是酸類、脂族烴、芳香烴及動植物油。適用于柴油發動機、燃料系統及化工廠的密封需求。不建議使用于酮類、低分子量的酯類及含硝的混合物。一般使用溫度范圍為 -20~250 ℃。
FLS氟硅橡膠Y型圈——其性能兼有氟素橡膠及硅橡膠的優點，耐油、耐溶劑、耐燃料油及耐高低溫性均佳。能抵抗含氧的化合物、含芳香烴的溶劑及含氯的溶劑的侵蝕。一般用于航空、航天及軍事用途。不建議暴露于酮類及剎車油中。一般使用溫度范圍為 -50~200 ℃。
Definition:
The cross section of Y-shaped seal ring is Y-shaped, which is a typical lip-shaped seal ring. It is widely used in reciprocating sealing devices, and its service life is higher than that of O-ring. The applicable working pressure of Y-shaped sealing ring is not more than 40MPa, and the working temperature is - 30~80 ℃.
Classification:
The Y-shaped seal ring can be divided into wide Y-shaped seal ring, narrow Y-shaped seal ring and Yx-shaped seal ring according to the ratio of length to width of the section. The pressure resistance of the wide cross-section Y-shaped seal ring is slightly less than that of the narrow Y-shaped seal ring, which can only be used in the working environment with P<20MPa, while the narrow Y-shaped seal ring can be used in the situation with working pressure P<32MPa.
According to whether the height of the two lips is the same, the Y-shaped sealing ring can be divided into the unequal height lip Y-shaped sealing ring for the shaft, the unequal height lip Y-shaped sealing ring for the hole and the universal equal height lip Y-shaped sealing ring for the shaft hole. The Y-shaped sealing ring can be divided into nitrile rubber Y-shaped sealing ring, fluororubber Y-shaped sealing ring, polyurethane rubber Y-shaped sealing ring and so on due to its different manufacturing materials.
Working speed range: 0 01～0. 6m/s； 0.05~0.3m/s when fluororubber is used; When polyurethane rubber is used, it is 0.01~lm/s. Polyurethane rubber is the best material for the sealing performance, service life and working pressure limit of Y-shaped sealing ring under different retaining rings.
Product features:
Reliable sealing performance;
Low friction resistance and smooth movement;
Good pressure resistance, wide applicable pressure range;
Simple structure and low price;
Easy installation.
Purpose:
NBR nitrile Y-ring - suitable for use in petroleum hydraulic oil, glycol hydraulic oil, diester lubricating oil, gasoline, water, silicone grease, silicone oil and other media. It is the most widely used and lowest cost rubber seal. It is not applicable to polar solvents, such as ketones, ozone, nitrohydrocarbons, MEK and chloroform. The general operating temperature range is - 40~120 ℃.
HNBR hydrogenated nitrile Y-ring - has excellent corrosion resistance, tear resistance and compression deformation resistance, and good ozone resistance, sunlight resistance and weather resistance. It has better abrasion resistance than nitrile rubber. It is applicable to washing machinery, automobile engine system and refrigeration system using new environment-friendly refrigerant R134a. It is not recommended to use in alcohol, ester or aromatic solutions. The general operating temperature range is - 40~150 ℃.
SIL silicone rubber Y-ring has excellent heat resistance, cold resistance, ozone resistance and atmospheric aging resistance. It has good insulation performance. However, the tensile strength is worse than that of ordinary rubber and does not have oil resistance. Suitable for household appliances such as electric water heaters, electric irons, microwave ovens, etc. It is also applicable to all kinds of articles in contact with human body, such as water bottles, drinking fountains, etc. It is not recommended to use in most concentrated solvents, oils, concentrated acids and sodium hydroxide. The general operating temperature range is - 55~250 ℃.
VITON fluororubber Y-ring - superior to silicone rubber in high temperature resistance, excellent weather resistance, ozone resistance and chemical resistance, but poor in cold resistance. It is resistant to most oils and solvents, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons and animal and vegetable oils. It is applicable to the sealing requirements of diesel engines, fuel systems and chemical plants. It is not recommended to use in ketones, low molecular weight esters and mixtures containing nitrate. The general operating temperature range is - 20~250 ℃.
FLS fluorosilicone rubber Y-ring - its performance combines the advantages of fluorosilicone rubber and silicone rubber, and it has excellent oil resistance, solvent resistance, fuel oil resistance and high and low temperature resistance. It can resist the attack of oxygen-containing compounds, solvents containing aromatic hydrocarbons and solvents containing chlorine. It is generally used for aviation, aerospace and military purposes. Exposure to ketones and brake oil is not recommended. The general operating temperature range is - 50~200 ℃.
