            固定凸緣法—應用于F型和FC型膜片

            陷型唇緣— 陷型唇緣不僅可以提高制造的數量并降低成本,在設計上類似于束線帶,但其唇緣是 汽缸 或是 閥帽的一部分。唇緣應盡量輕薄與靈活,以確保凸緣的固定。F型膜片 | FC型膜片

            Swaged Lip

            束線圈— T這種方法有助于提高制造的數量并降低成本。它是一個與整體分離,由特殊壓縮工具安裝的束線圈,這些束線圈由輕薄,柔韌的材質做成,所以模塑凸緣所需的力就不會過度擠壓到膜片與法蘭。

            Crimped Ring

            固定凸緣法—應用于D型和DC型膜片

            樞軸擺動桿— 這可以提供快速的安裝和分拆。樞軸擺動桿連接至法蘭外緣,而其中心的螺絲有確保了閥帽和法蘭的相連。 D型膜片 | DC型膜片

            Pivoted Rocking Bracket

            環鉗—V型環鉗能通過移開夾緊把手很快地分拆。旋轉護圈板90度可以將其移除,兩翼與固定螺絲將掉入鎖眼。

            Ring Clamp

            斜緣護圈板 —無需法蘭螺栓作為斜邊環進入到擴展的汽缸外緣凹槽里。這加載到交配珠罩裝配,普遍產生低鎖模力。

            Beveled Edge Retainer Plate

            固定凸緣法—應用于O型和OA型膜片

            環鉗— 這種方法能用于高體積,低成本的應用,并能消除典型凸緣構造和凸緣螺栓。O型膜片 | OA型膜片

            Crimped Ring

            罩圈 — 這種常見的方法使外殼外圓徑部分間隙最小,陽螺紋通過使用拉制金屬氣缸殼做出,減少成本。

            Bezel Ring

            榫槽式閥帽 — 這種方法需要足夠的圓周夾緊螺栓,從而凸緣螺栓中不會發生變形。建議你為在鑄件或模壓閥帽中的珠形槽做準備。
