7、。High pressure gaskets or seals encounter numerous difficulties in insuring a sealable relation between the seal and the pressure vessel during operations of varying pressures. For example, if a high pressure gasket or seal is used on a rough sealing surface, the seal must accordingly be pliable or

However, gaskets that are typically pliable are not suitable for high temperature operations inasmuch as they are typically limited to temperatures of approxi

10、, irrespective of the significant increase in costs encountered in producing such mirror-like surfaces. 然而，通常柔软的垫片不适合高温操作情况，因为它们通常限制在约为450°华氏度的温度下。另一方面，由于温度条件超过了这种柔韧垫片和常见金属垫片承载能力。这种金属垫片却需要非常好的表面接触面，这是难以实现的，甚至更加难以维护和服务，更不论在生产这种镜面表面会显著增加成本。As a compromise, metal gaskets sealing on metal surfaces

Such coatings are sufficiently plastic and pliable to fill in the irregularities of the sealing surface where a seal must necessar

Since such coatings are expensive, only small amounts of such coating materials may be used in order to minimize costs. 作为一种折衷办法，当涂有

The pressure vessel seal S is for sealing a pressure vessel joint J of a pressure vessel P to preven

27、t fluid migration therebetween the pressure vessel seal S and the pressure vessel P. The pressure vessel seal S includes generally an annular seal ring R, coating means C with the annular seal ring R, and coating reservoir means M formed with the annular seal ring R. 在图纸中，字母S一般地指本发明压力容器密封S。压力容器密封S是密

28、封一个压力容器P的压力容器接头J，以防止压力容器密封S和压力容器P之间的液体流动。压力容器密封S通常包括一个环形密封环R，环形密封环R带有涂层工具C，和涂层储藏手段M形成环形密封环R。本发明的压力容器密封S是适合被用于一个压力容器P内。这种压力容器P是典型地由一种压力容器接头J以最好出现在图1的方式制成。压力容器P的压力容器接头J可能包括压力容器10,12部分，这部分通常是圆筒形状。压力容器的10部分可能包括接头齿距的10a,10b,10c,同时压力容器部分12包括接头齿距的12a,12b。最好的接头齿距10a,10b,10c,12a,12b在相交部分是本质兼用的结构和是装配了接头齿距12a适

29、合在接头齿距10a，10b两者中。接头齿距12b适合在接头齿距10b,10c两者中。最好接头齿距12a,12b有一个轻微的锥度，这样压力容器10，12部分就可拉伸在一起，接合点齿距被挤成一个又一个。适当的固定销如14,16，被用于压力容器的10,12部分内的适当形成的开口里，确保压力容器10,12部分连接在一起。那固定销14,16也有轻微的锥度结构，这结构能增强图纸中容器10,12部分的紧固。The pressure vessel seal S of the present invention is adapted to be used within a pressure vessel P.

30、Such pressure vessels P are typically made up in such a fashion that there is a pressure vessel joint J as best seen in FIG. 1. The pressure vessel joint J of the pressure vessel P may include the pressure vessel sections 10, 12 which are of a generally cylindrical shape. Pressure vessel section 10

31、may include joint fingers 10a, 10b, 10c while pressure vessel section 12 includes joint fingers 12a, 12b. Preferably joint fingers 10a, 10b, 10c, 12a, 12b are of a substantially compatible configuration in cross section and are configured such that the joint finger 12a fits between joint fingers 10a

32、, 10b and joint finger 12b fits between joint finger 10b, 10c. Preferably, joint fingers 12a, 12b are of a slight taper such that as the pressure vessel sections 10, 12 are drawn together, the joint fingers are wedged into one another. Appropriate vessel pins such as 14, 16 are disposed within a sui

33、tably formed openings in the pressure vessel sections 10, 12 to secure the pressure vessel sections 10, 12 together. The vessel pins 14, 16 are also of a slight, tapered configuration which enhances the drawing together of the vessel sections 10, 12. For example, vessel pin 14 may be placed through

34、opening 10d in joint finger 10a, opening 12c in joint finger 12a, opening 10e in joint finger 10b, into opening 12d formed in joint finger 12b, thereinto opening 10f formed within joint finger 10c of the pressure vessel P for securing the pressure vessel joint J together. The pressure vessel section

35、 12 includes an interior wall 12e which may include a protective layer 12f mounted adjacent thereto with such protective layer 12f adapted to protect the interior wall 12e of pressure vessel section 12 from the effects of the contents within the pressure vessel P. Pressure vessel section 10 is prefe

36、rably formed having an interior surface 10 g as best seen in FIG. 2 disposed between annular surfaces 10h, 10i, with abutting surface 10j formed adjacent to annular surface 10h and adapted to be in close proximity to interior wall 12e. 例如，固定销14可能被放置于穿过接缝齿距10a中的10b的孔，接缝齿距12a中的12c的孔，接缝齿距10b中的10e的孔，穿过接

37、缝齿距12b中的12d的孔，其中穿过10f形成的孔，这孔在压力容器P的接缝齿距10c内，是为了使压力容器接头J的紧固性更安全。压力容器12部分包括内壁12e,可能还包括一个保护层12f安装在相邻地方，这样的保护层12f适用于保护压力容器12部分的内壁12e不受压力容器P内物料的影响。压力容器10部分有更好地形成的一个内表面10g，如在图2所示。被用于圆环表面10h,10i和相邻表面10j形成的相邻的圆环表面10h两者上，和被用于相邻的内壁12e上。本发明的压力容器密封元件S包括一个环形密封环R。环形密封环R包括环18.环18更好地形成有一个第一环形外表面18a,适用于处理相邻压力容器12部分的

38、压力容器接缝J的内壁12e和一个第二环形外表面18b与第一环形外表面18a形成毗邻，18b被用于连接压力容器接缝J的内表面10g。凹腔18c形成在第一环形外表面18a与外端18d里和凹腔18e形成在第二环形外表面18b与外端18f里。形成在第一环形外表面18a的侧向部分18g是在凹腔18c和第一环形外表面18a的外端18d之间.The pressure vessel seal S of the present invention includes an annular seal ring R. The annular seal ring R includes ring 18. The ring

39、 18 is preferably formed having a first outer annular surface 18a adapted to be disposed adjacent the interior wall 12e of pressure vessel section 12 of the pressure vessel joint J and a second outer annular surface 18b formed adjoining the first outer annular surface 18a and adapted to be disposed

40、adjacent the interior surface 10g of the pressure vessel joint J. A first cavity 18c is formed in the first outer annular surface 18a adjacent outer extremity 18d and a second cavity 18e is formed in the second outer annular surface 18b adjacent the outer extremity 18f. A first undercut portion 18g

41、is formed in the first outer annular surface 18a between the first cavity 18c and the outer extremity 18d of the first outer annular surface 18a. A second undercut portion 18h is formed from the second outer annular surface 18b between the second cavity 18e and outer extremity 18f of the second oute

42、r annular surface 18b. A first inner annular surface 18i is preferably formed adjacent outer extremity 18d with second inner annular surface 18j formed between the first inner annular surface 18i and outer extremity 18f. As a consequence, the annular seal ring R of the present invention is of a subs

43、tantially quadrilateral configuration having two truncated end portions at the outer extremities 18d, 18f, with such quadrilateral configuration being substantially of that of a parallelogram. 形成在第二环形外表面18b的侧向部分18h是在第二凹腔18e和第二环形外表面18h的外端18f之间。第一环形内表面18i更好形成相邻的外端18d和第二环形内表面18j形成在第一环形内表面18i和外端18f之间。因此

44、，本发明的环形密封环R本质上是一个四边形结构，外端18d，18f里有两个斜截头的末端，这种四边形结构大体上是一个平行四边形。环18能由任何适合的高强度材料，如不锈钢，如任何适合的合金，或类似的，是最好的。这取决于本发明压力容器密封元件S受到压力容器P的环境里的影响。这一设想选择的材料必须耐腐蚀，耐高温，以及禁得住随着情况要求的高压。然而，材料应该在稍高的压力下是能够收缩的，却没有显示任何金属疲劳，开裂或类似的。如下文更详细的讨论。压力容器密封S的环形密封环R是由这些形成的，其中当压力容器P在较低压力条件下，第一环形外表面18a与压力容器接缝J的内壁12e有一个角度关系，以及环形密封环R的第二环

45、形外表面18b，当压力容器P在较低压力条件下，18b与压力容器接缝J的内壁10g有一个角度关系。这在环形密封环R和对应的密封表面10g两者间的配对角度，使压力容器接缝J的内壁12e与环形密封环R最少的一部分开始先接触，因此在高压时，只需要一个较低的预紧力。It is preferable that the ring 18 be formed of any suitable high strength material such as stainless steel, any suitable alloy, or the like, dependent upon the environment

46、to which the pressure vessel seal S of the present invention is subjected to within the pressure vessel P. This contemplates selecting materials that must withstand corrosive effects, high temperatures, as well as high pressures as the situation demands. However, the material should be able to flex

47、slightly under high pressures without demonstrating any metal fatigue, cracking or the like, as discussed more fully hereinbelow. The annular seal ring R of the pressure vessel seal S is formed such that the first outer annular surface 18a is at an angle with respect to the interior wall 12e of the

48、pressure vessel joint J when the pressure vessel P is under minimal pressure conditions and that the second outer annular surface 18b of the annular seal ring R is at an angle with respect to the interior surface 10g of the pressure vessel joint J when the pressure vessel P is under minimal pressure conditions.
