When install, first the two ellipse oval flange on positive - negative pressure measuring container of transmitter would be take off, then take three valve units install on transmitter, turn tighten four screws, final take ellipse oval flange solidly install on three valve units
安裝時選將變送器正負壓測量容室上的兩只橢圓形法蘭取下，然後將三閥組安裝于在變送器上，旋緊四個螺釘，最後將橢圓形法蘭牢固安裝在三閥組上。Ball valve design includes reinforced / enhanced ptfe seats and electroless nickel plated brass ball, blow - out proof pressure retaining stem, and low profile oval handle
球閥結構包括強化聚四氟乙烯（ ptfe ）閥座和非電解鎳鍍層黃銅球體，防吹出壓力保持閥桿，以及低矮型橢圓手柄。The paper analyzed the struture of the tri - eccentric butterfly vavle at length, defined the tri - eccentric butterfly valve, educed the geometry function and its characteristic about the section of the butterfly disc. the results indicate : the parallel contour line across butterfly disc thickness is normal ellipse, thereby eslablished function relations between its geometry parameters ( long axis and short axis ) of three primary sections of the butterfly disc and the tri - eccentricity ; in order to avoid interference between the butterfly disc and the valve seat as well as the valve body, combining the torque, we obtained the feasible range about the rotation center of the tri - eccentric butterfly vavle
本文主要分析了三偏心蝶閥的結構，給出了三偏心的定義，推導出了蝶板截面的幾何方程及其性質，結果表明，沿蝶板厚度的平行截面輪廓線為標準的橢圓形，進而推導出了蝶板幾個主要截面的幾何參數（長軸、短軸）與三個偏心之間的函數關系；考慮到蝶板啟閉過程中避免與閥體及閥座發生干涉，結合蝶板的啟閉扭矩，確立了三偏心蝶閥回轉中心的適宜區域。This advanced design features three - way eccentricity and unique elliptical seat geometry ensuring compressive sealing around entire seat and a “ tight ” bubble free valve
先進的結構特徵包括三向偏心率和獨特的橢圓形閥座，這些特徵確保整個閥座周圍具有壓縮力的密封，確保閥門實現無氣泡「氣密性」密封。分享友人
