一、執(zhí)行標(biāo)準(zhǔn)：
1、設(shè)計(jì)和制作：GB/122371989； API1608
2、檢驗(yàn)和試驗(yàn)：GB/T13927-1992； API1608
3、法蘭連接：JB/T79.1-2 -1994； ASME/ANSIB16.5
4、結(jié)構(gòu)長度：GB/T12221-1989； ASME/ANSIB16.10
二、設(shè)計(jì)特點(diǎn)：
1、鍛鋼設(shè)計(jì)：
閥體與球芯全部采用鍛鋼材料，保證閥門在各種工作壓力等級壓力下都具有很好的強(qiáng)度和金屬致密性。也可按用戶要求采用鑄件。
2、雙重阻塞和排泄
當(dāng)閥門處于關(guān)閉位置時(shí)，進(jìn)出口側(cè)的閥座將閥體中腔和管線壓力阻斷，閥體中腔的滯留物可以通過泄放閥排泄。排泄裝置具有一下機(jī)能：
A． 通過排泄裝置可以檢查閥座是否發(fā)生泄露，以防止不可見的內(nèi)漏。
B． 管線有工作壓力時(shí)，閥門處于全開或全關(guān)狀態(tài)，可更換閥桿處的填料，
C． 閥門全關(guān)時(shí)，打開泄放閥，可以排泄體腔的積壓和沉積物。
