具体实施方式 DETAILED DESCRIPTION
按照本发明具有位于塔盘10内的塔盘开口2和阀主体3的塔盘阀1的第一实施例表示在图1和2中。 According to the present invention having a tray located within the opening 10 of the tray 2 and the valve body of the first embodiment of a tray 3 of the valve shown in Figures 1 and 2. 允许蒸汽可变地穿过塔盘开口2的阀主体3与其分开表示。 Allowing steam to pass through the tray variable valve body 3 spaced apart from the opening 2 of Fig. 图2表示穿过具有插入阀主体3的塔盘阀2的纵向截面图。 Figure 2 shows a valve body having an insertion through the tray 3 is a longitudinal sectional view of the valve 2. 制造成与开口的边缘20配合的阀主体3包括顶板4和布置在板3的边缘处并且向下垂直指向的两个引导伸出部分5。 Manufactured to fit with the edge of the opening 20 of the valve body 3 includes a top plate 4 and disposed at the edges of the guide plate 3 and the two vertically directed downwardly protruding portion 5. 开口的边缘20具有矩形形状，该形状具有两个短边21和两个长边22。 Edge of the opening 20 has a rectangular shape which has two short sides 21 and two long sides 22. 顶板4相应地具有位于一个矩形上的四个直的侧边41和42，其中侧边41是弯曲边，并且侧边42静置在塔盘10之上的开口的边缘20外部。 Edge of the opening of the top plate 4 respectively having a rectangle located on the four straight sides 41 and 42, wherein the side edge 41 is bent, the side 42 and allowed to stand at 10 above the tray 20 outside. 引导伸出部分5具有倒钩6，阀主体3通过倒钩锚固在开口边缘20上，使得行程受到限制，并且在最大量蒸汽通过时，阀主体3不能升高到塔盘开口2之外。 5 has a guide portion projecting barbs 6, the valve body 3 by the barbs 20 anchored in the opening rim, so that the stroke is limited, and, when the maximum amount of steam through the valve body 3 can not be raised to the tray opening than 2. 顶板4在长侧边42处具有凹痕状、向下指向的上升部分40(凹痕)，通过凹痕确保阀主体1总是可以允许最小蒸汽通过量。 4 in the long side of the top plate 42 has a dent-like, downwardly directed rising portion 40 (dents), through the dents to ensure that the valve body 1 can always allow the minimum steam throughput. 除了凹痕之外，板边缘位于下面称为板平面的一个平面上。 In addition to the dent, the upper and lower panel edge located in a plane known as the plane of the plate. (除了顶板4处的凹痕40之外，同样在开口边缘20处在塔盘10内具有相应向上指向的凹痕)。 (In addition to the top plate 4 of the dents 40, also in the opening edge 20 is in the tray 10 has a corresponding upwardly directed indentations). 引导伸出部分5的外表面各自包括行程区域50，该区域垂直于板平面。 The outer surface of the guide portion 5 comprises a projecting each stroke region 50, the region perpendicular to the plane of the board. 倒钩6布置在径向相对站立的两个引导伸出部分5处。 6 barbs disposed in diametrically opposed stand two guide projecting portion 5.
按照本发明，相对于插入来说，针对阀主体3使用一种材料并选择一种形状，使得所造成的阀主体3的弹性变形和任选的部分塑性变形大部分局限于顶板4。 According to the present invention, with respect to the insert, the valve body 3 against the use of a material and select a shape, such that the valve body caused by the elastic deformation and optionally 3 parts of plastic deformation was largely restricted to the top plate 4. 由于作为插入阀主体3所需力作用结果的弯曲动能和抵抗动能相互协作，造成最大弯曲应力，出现可看到的向上拱起的变形。 Kinetic energy due to the bending force required to insert the valve body 3 as a result of the role of the kinetic energy of mutual cooperation and resistance, resulting in maximum bending stress, deformation occurs upward arch can be seen. 按照本发明，此位置在塔盘阀1内的阀主体3的顶板4上。 According to the present invention, this location in the tray inside the valve body 1 on the top plate 3 of 4.
如果除了小的残留变形之外，在插入之后出现塑性变形，这种变形可以在被插入的阀主体3处通过将力作用施加在顶板4上来逆转。 If, in addition a small residual deformation, plastic deformation after the insertion, this deformation can 3 is inserted into the valve body by the force exerted onto the top plate 4 reversed. 偏心定位的凹痕40同样允许在相反方向上临时弯曲，从而实际上在没有残留变形痕迹的的情况下实现原来提供的形状。 Eccentrically positioned indentations 40 also allows the temporary bend in the opposite direction, so that in fact in the absence of traces of residual strain originally provided to realize shape. 例如凹槽、细槽和孔口形式的薄弱部分可设置在顶板4内，这些部分减小局部的抵抗动能，并有助于向上拱起的形成(参考图7)。 E.g. weakened portion recess, slots and apertures can be provided in the form of top plate 4, these portions reduce the local resistance to the kinetic energy and contribute to the formation of arch upward (see Fig. 7).
因此，引导伸出部分5的间距与其垂直长度相比相对大，使得阀主体3的所述变形大部分局限于顶板4。 Thus, the length of the guide projecting portion perpendicular thereto spacing is relatively large compared to 5, so that the valve body 3 is deformed largely restricted to the top plate 4. 引导伸出部分5以及倒钩6实际上在插入时保持未变形。 5 and the guide projecting portion 6 remains substantially the barbs during insertion undeformed.
每个倒钩6以突片形式制成。 Each barb is made in the form of 6 tabs. 它具有平行于板平面定位的平面上侧表面61(或者只有直的上边缘610，见图6)。 It has an upper plane positioned parallel to the plane of the plate side surface 61 (or only the straight upper edge 610, see Figure 6). 倒钩6还具有带有伸出倾斜部的外侧表面62。 6 also has a barb extending outer surface 62 with the inclined portion. 对于此侧表面62来说，从上边缘610开始并连续向下，到垂直于板平面(未示出)指向的中心轴线的间距减小。 For this the side surface 62, the upper edge 610 from the start and continuously downward, to a plane perpendicular to the plate (not shown) of the pitch point to the center axis is reduced. 由于在最大蒸汽通过塔盘阀1时，上侧表面61(或者上边缘610)不造成阀主体3的倾斜位置；行程区域50因此向上受到清楚限制。 Since the maximum steam valve 1 through the tray, the upper surface 61 (or the upper edge 610) does not cause the inclined position of the valve body 3; stroke region 50 thus being clearly limits upward. 因此，由于倒钩6的特殊结构，可以重复利用蒸汽通过的最大值。 Thus, due to the special structure of the barbs 6, can be reused by the maximum steam. 从用于限制行程的弯曲表面不允许这种重复性的现有技术中得知了具有倒钩的塔盘阀。 From a curved surface for limiting the stroke of the prior art do not allow this repetitive in that the valve tray having barbs.
阀主体3可由金属片材成形而成。 The valve body 3 may be made of metal sheet forming. 图3表示通过进一步成形来制造图1的阀主体3的片材金属31的成形件。 Figure 3 shows manufactured by further forming the valve body of Figure 1 a metal sheet 3 forming member (31). 顶板4、引导伸出部分5以及倒钩6形成片材金属31的连续部件的各个部分。 The top plate 4, the guide projecting portions 5 and 6 are formed each barb portion of the sheet metal member 31 is continuous. (引导伸出部分5和/或倒钩6还可作为分开部件制造，这些部件一起结合到阀主体3上)。 (The guide projecting portion 5 and / or 6 may barbs manufactured as separate components, a combination of these components together on to the valve body 3). 片材金属的成形通过冲压或切割来进行，并且还包括塑性成形，特别是片材金属件的弯曲或冲压。 Forming the sheet metal by punching or cutting is performed, and further comprising forming, in particular bending or punching of the sheet metal member.
