產(chǎn)品特點(diǎn)Features:
的閥桿防竄出設(shè)計(jì),即方便拆卸維護(hù),又保證了使用的安全性。Non blowout stem design(Patent design by HITEK valve) for ease of assembly and safe operation.
采用優(yōu)質(zhì)的INCONEL718波形彈簧,相對(duì)于普通彈簧,體積小,彈力大。High quality INCONEL718 wave spring design with the features of compact profile and high ball to seat loading force.
采用浮動(dòng)球設(shè)計(jì),入口閥座前的波形彈簧提供一個(gè)初始的密封推力,并使球體與閥座緊緊貼合,工作狀態(tài)時(shí),管線壓力推動(dòng)球體提供主要密封力。With the floating ball design, the waveform spring in front of the inlet seat provides the initial sealing thrust from the ball to the seat. During operation, system pressure provides the main sealing force.
球體與閥座密封面都為同一種材質(zhì),確保有相同的熱膨脹系數(shù),能夠抵抗溫度突變而產(chǎn)生的熱沖擊。The ball and seat cover are made of the same material to ensure the same thermal expansion coefficient and to withstand thermal shock caused by temperature mutation.
ISO標(biāo)準(zhǔn)化支架盤預(yù)留了多種規(guī)格的法蘭孔,為自動(dòng)化連接提供方便。ISO mounting flange as standard to suit all main types of actuator。
限位塊可以防止閥門的過開或者過關(guān),確保閥門行程的精確性。Travel stop to ensure accurate open and close position
兩件式閥蓋,閥蓋與壓套接觸面為球形面,保證壓套的對(duì)中,和對(duì)填料壓緊力的均勻性。The packing gland is designed to ensure even loading of the packing
采用楔式石墨環(huán)加蝶形彈簧的填料組合,對(duì)填料的預(yù)緊提供動(dòng)態(tài)補(bǔ)償,避免填料失效。High quality graphite packing with Belleville spring provide continuous and stable sealing force.
