          概述柱塞式閘閥UZ41H UZ41SM是由閥體、閥蓋、閥桿、柱塞、導向套、密封環、手輪等零件組成 (如圖)。當手輪旋轉時,通過閥桿帶動柱塞在導向套中上、下往復運動,使柱塞端部斜錐面與閥座面完成閥門的開啟與關閉功能。 在閥門中柱塞與密封環采用過盈配合,通過調節中法蘭螺栓預緊力,使密封環壓縮所產生的側向力與閥體中孔面及柱塞外圓密封從而耐磨 性高的無毒新型密封材料,所以密封可靠、經久耐用,從而提高閥門的使用壽命。 柱塞閘閥是根據原有的閘閥連接尺寸設計制造的,由于閘閥在使用過程中出現外漏,密封環帶復性較差,使用壽命短等缺點,本柱塞閘閥結合了柱塞閥的無泄漏優點和閘閥啟閉快又耐高溫高壓的特點,成為一種結構新穎的無泄漏柱塞閘閥。適用范圍當前柱塞閥被廣泛用于石油化工、化工、煤氣、天然氣、液化石油氣、暖通行業以及一般工業中。結構示意圖主要連接、結構尺寸DN(mm)            尺寸(mm)UZ41SM-16Y、P、R1520253240506580100125150200250300350400L130150160180200250265280300325350400450500550600H1701902102502703003403804204505406407408509701100W100100120140160180200240270310340400520640760900D95105115135145160180195215245280335405460520580K657585100110125145160180210240295355410470525D14555657885100120135155185210265320375435485t14141416161618202022242630303436n-φ4-144-144-144-184-184-184-188-188-188-188-2312-2312-2512-2516-2516-30 DN(mm)            尺寸(mm)UZ41H-25C(Y、P、R)1520253240506580100125150200250300350400L130150160180240250265280300325350400450500550600W100100120140160180200240280310340400520640760900D95105115135145160180195230270300360425485550610K657585100110125145160190220250310370430490550D14555657885100120135160188218278332390448505t16161618182022222428303436404448n-φ4-144-144-144-184-184-188-188-188-238-258-2512-2512-3016-3016-3416-34 DN(mm)            尺寸(mm)UZ41SM-25C、P、R1520253240506580100125150200250300350400L130150160180200250265280300325350400450500550600H1701902102502703003403804204605406407408509801100W100100120140160180200240280310340400520640760900D95105115135145160180195230270300360425485550610K657585100110125145160190220250310370640490550D14555657885100120135160188218278332485448505t161616181820222224283034364304448n-φ4-144-144-144-184-184-188-188-238-238-258-2512-2512-3039016-3416-34 DN(mm)            尺寸(mm)UZ41SM-40C、P、R1520253240506580100125150200250300350400L130150160180200265270280300325350400450500550600H1802002202602803103503804304705506507508609901110W100100120140160180200240280310340400520640760900D95105115135145160180195230270300375445510570655K657585100110125145160190220250320385450510585D14555657885100120135160188218282345408465535t16161618182022222428303840424652n-φ4-144-144-144-184-184-188-188-188-238-258-2512-3012-3416-3416-3416-41
