柱塞截止閥是由閥體、閥蓋、閥桿，柱塞，導(dǎo)向、密封環(huán)、手輪等零件組成（如圖）。當(dāng)手輪旋轉(zhuǎn)時(shí)，通過閥桿帶動(dòng)柱塞在導(dǎo)向套中上、下往復(fù)運(yùn)動(dòng)，使柱塞端部斜錐面與閥座錐面完成閥門的開啟與關(guān)閉功能。柱塞截止閥中柱塞與密封環(huán)間采用過盈配合，通過調(diào)節(jié)中法蘭螺栓預(yù)緊力，使密封環(huán)壓縮所產(chǎn)生的側(cè)向力與閥體中孔面柱塞外圓密封，從而保證了閥門的密封性，杜絕了內(nèi)泄漏。由于密封環(huán)采用回彈性強(qiáng)，耐磨性高的新型密封材料，所以密封可靠，經(jīng)久耐用。從而提高了柱塞截止閥的使用壽命。柱塞截止閥結(jié)合柱塞閥的無泄漏有點(diǎn)和截止閥啟閉快的特點(diǎn)，成為一種結(jié)構(gòu)新穎，用途廣泛的新產(chǎn)品。 柱塞截止閥結(jié)構(gòu)規(guī)范 ? tttttttttttttttttttttttttttt
