Z41H國標(biāo)鋼制閘閥�(chǎn)品應(yīng)用:
國標(biāo)閘閥適用于公稱壓力PN1.6�6.4MPa,工作溫度-29�600℃的石油、化�、制藥、化�、電力行�(yè)等各種工況的管路�,切斷或接通管路介�(zhì),不能作�(diào)節(jié)和節(jié)�。適用介�(zhì)為:�、油品、蒸�、酸性介�(zhì)等�
Z41H國標(biāo)鋼制閘閥�(jié)�(gòu)特點及優(yōu)勢:
閘閥的結(jié)�(gòu)�(shè)計合�,密封可靠,通道流暢,流阻系�(shù)��
閘板、閥座密封面用鐵基合金堆焊或司太立鈷基硬�(zhì)合金堆焊而成,耐磨、耐高�、耐腐蝕、抗擦傷性能�、使用壽命長�
采用楔式彈性閘板或鋼性楔式單閘板�(jié)�(gòu),中大口徑設(shè)置滾動軸�,開�(guān)靈活,啟閉輕��
閥桿�(jīng)�(diào)�(zhì)及表面氮化處�,有良好的抗腐蝕�,抗擦傷性和耐磨��
可采用各種配管法蘭標(biāo)�(zhǔn)及法蘭密封面型式,滿足各種工程需要及用戶要求�
閥體材料品種齊全,填�、墊片可根據(jù)實際工況或用戶要求合理選�,能適用于各種壓力、溫度及介質(zhì)工況�
Z41H國標(biāo)鋼制閘閥安裝使用�
1.安裝前須檢查閥門�(nèi)腔和密封面等部位,不允許有污物或砂粒附著�
2.各連接部位螺栓,要求均勻擰��
3.檢查填料部位要求壓緊,既保證填料的密封�,也要保證閘板開啟靈��
4.用戶在安裝閥門�,必須校對閥門型號,連接尺寸及注意介�(zhì)流向,保證與閥門要求一致��
5.用戶在安裝閥門�,必須預(yù)留閥門�(qū)動的必要空間�
6.�(qū)動裝置的接線須按線路圖�(jìn)��
7.閘閥�(chǎn)品必須定期保�(yǎng),不得隨意碰撞及擠壓,以免影響密��
