DZ41W低溫閘閥
|
產(chǎn)品型號(hào):DZ41W/DZ41Y
|
公稱壓力:PN10-160MPa/Class150LB-1500LB
|
適用溫度:-196℃~200℃
|
適用介質(zhì):液化天然氣、液化石油氣、液氮、液氨
|
產(chǎn)品簡(jiǎn)介
----------------------------------------------------------------------
DZ41W低溫閘閥適用于甲烷、液態(tài)天然氣、已烯、二氧化碳、液氨、液氧、液氮、液氫等低溫介質(zhì),低溫閘閥有二種閥蓋設(shè)計(jì)形式。第一種是螺栓式閥蓋,按這種設(shè)計(jì)的閥門,其閥體與閥蓋用螺栓螺母連接,纏繞式墊片(316夾柔性石墨制造)。客戶有特殊要求時(shí)也可采用金屬環(huán)連接。第二種設(shè)計(jì)形式是焊接式閥蓋,按這種設(shè)計(jì)形式的閘閥,其閥體與閥蓋用螺紋連接,全焊密封??蛻粲刑厥庖髸r(shí)也可采用透焊連接。低溫閘閥特點(diǎn)
1、為防止中腔異常升壓,在閘板的進(jìn)口側(cè)設(shè)置了泄壓孔2、根據(jù)閥門的工作溫度確定閥蓋的頂部長(zhǎng)度,確保閥桿填料的可靠密封
3、根據(jù)工作溫度合理選用填料,墊片等零件的材料
4、低溫閘閥嚴(yán)格控制材料的化學(xué)成份及低溫沖擊韌性等力學(xué)性能指標(biāo)
5、低溫閘閥采用多種配管法蘭標(biāo)準(zhǔn)及密封面型式,適用于各種工程需要
