閘閥按閥桿的構(gòu)造可分為：1、明桿閘閥：閥桿螺母在閥蓋或支架上，開閉閘板時(shí)，用旋轉(zhuǎn)閥桿螺母來實(shí)現(xiàn)閥桿的升降。這種結(jié)構(gòu)對(duì)閥桿的潤滑有利，開閉程度明顯，因此被采用。2、暗桿閘閥：閥桿螺母在閥體內(nèi)，與介質(zhì)直接接觸。開閉閘板時(shí)，用旋轉(zhuǎn)閥桿來實(shí)現(xiàn)。這種結(jié)構(gòu)的優(yōu)點(diǎn)是：閘閥的高度總保持不變，因此安裝空間小，適用于大口徑或?qū)Π惭b空間受限制的閘閥。此種結(jié)構(gòu)要裝有開閉指示器，以指示開閉程度。這種結(jié)構(gòu)的缺點(diǎn)是：閥桿螺紋不*無法潤滑，而且直接接受介質(zhì)侵蝕，容易損壞。明桿閘閥和暗桿閘閥的主要區(qū)別：1、暗桿法蘭閘閥的提升螺桿是只旋轉(zhuǎn)而無上和下移動(dòng)，外露的只是一根桿，其螺母是固定在閘板上，通過螺桿的旋轉(zhuǎn)來提升閘板，沒有可見的門架;明桿法蘭閘閥的提升螺桿是外露的，螺母緊貼手輪且是固定的（不旋轉(zhuǎn)也不軸向移動(dòng)），通過旋轉(zhuǎn)螺桿來提升閘板，螺桿與閘板只有相對(duì)的旋轉(zhuǎn)運(yùn)動(dòng)而無相對(duì)的軸向位移，外觀為有門形支架。2、暗桿閥門看不見絲杠，而明桿的能看見絲桿。3、暗桿閥門在開關(guān)時(shí)方向盤與閥桿是連接在一起相對(duì)不動(dòng)的，它是通過閥桿在固定點(diǎn)轉(zhuǎn)動(dòng)來帶動(dòng)閥瓣向上提升和下閘來完成啟閉的。明桿閥門則是通過閥桿與方向盤的螺紋傳動(dòng)來提升或者降下閥瓣。一個(gè)好的止回閥，使用方便正確的方法改善！貴陽鑄鋼止回閥壁厚</p><p

不銹鋼閘閥的種類,按密封面的配置可以分為平行閘板式閘閥和楔式閘板式閘閥,楔式閘板式閘閥可分為:單閘極式、彈性閘板式和雙閘板式；平行閘板式閘閥可分為雙閘板式和單閘板式。按閥桿的螺紋的位置可以劃分，暗桿閘閥和明桿閘閥兩種。閘閥關(guān)閉時(shí),密封面可以只靠介質(zhì)產(chǎn)生的壓力來密封,即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強(qiáng)制性密封的,即閥門關(guān)閉時(shí)，要依靠外力強(qiáng)行將閘板壓向閥座,以保證密封面的密封性。優(yōu)點(diǎn)：1、閥內(nèi)流體阻力小,密封面受介質(zhì)的沖刷和侵蝕較小。2、開閉比較省力。3、介質(zhì)的流向不會(huì)受到限制,不擾流、不降低壓力。4、形體簡(jiǎn)單,結(jié)構(gòu)長(zhǎng)度短，制造工藝性好，適用范圍廣。缺點(diǎn)：1、密封面之間易引起沖蝕和局部擦傷，維修比較困難。2、外形尺寸較大，開啟需要較長(zhǎng)空間，開閉時(shí)間長(zhǎng)。3、結(jié)構(gòu)較復(fù)雜。貴陽手動(dòng)對(duì)夾蝶閥怎么樣</p><p
