斯派莎克BRV73直接作用式減壓閥,用于蒸汽,壓縮空氣或其它氣體系統(tǒng)。在負(fù)載穩(wěn)定時(shí),可以準(zhǔn)確的控制下游壓力。*的制造工藝及技術(shù)保證其可靠耐用;不銹鋼內(nèi)部組件使其能應(yīng)用于大多數(shù)的工業(yè)設(shè)備中。BRV2減壓閥結(jié)構(gòu)緊湊,重量輕,安裝簡便,易于調(diào)試和設(shè)定,維修方便。斯派莎克BRV71和BRV73為球墨鑄鐵直接作用式減壓閥,BRV71為螺紋連接,BRV73為法蘭連接,主要用于蒸汽系統(tǒng)。結(jié)構(gòu)緊湊,設(shè)計(jì)簡單,表面高質(zhì)量的無電極涂鎳處理。與BRV2系列減壓閥相比,BRV71和BRV73內(nèi)有壓力平衡波紋管,可以平衡主閥頭上的壓差。主閥為平面密封,具有自清潔功能。斯派莎克SRV2直接作用式減壓閥,用于蒸汽,壓縮空氣或其它氣體系統(tǒng)。在負(fù)載穩(wěn)定時(shí),可以準(zhǔn)確的控制下游壓力。SRV2閥體材質(zhì)為316L奧氏體不銹鋼,因而主要應(yīng)用于潔凈蒸汽系統(tǒng)的壓力控制,同時(shí)也可用于其它傳統(tǒng)工業(yè)的蒸汽系統(tǒng)。
Spirax-Sarco valve mechanism for B4 series 15lb.inverted bucket steam trap.
Spirax-Sarco valve mechanism less bucket is the device that allows the condensate and air to drain from the trap. The mechanism is a lever and seat operation, it is held in place by screwing the seat into the outlet port within the trap. With the inverted bucket attached to this mechanism, the steam pressure within the bucket keeps the lever up in turn keeping the seat closed when steam is present. When the steam cools and turns to a liquid state (condensate), the trap fills with condensate causing the bucket to drop and this opens the seat to allow the condensate and air to drain.
斯派莎克直接作用式減壓閥BRV73閥門機(jī)制B4系列15lb.inverted吊桶式疏水閥。
斯派莎克直接作用式減壓閥BRV73機(jī)構(gòu)少鏟斗裝置,使冷凝水和空氣從陷阱排出。該機(jī)構(gòu)是一個(gè)杠桿和座椅的操作,它在適當(dāng)?shù)奈恢猛ㄟ^螺紋連接在座椅進(jìn)入出口端口陷阱內(nèi)舉行。與連接到這個(gè)機(jī)制倒斗,斗內(nèi)的蒸汽壓力保持桿,反過來保持座位關(guān)閉時(shí)蒸汽存在。當(dāng)蒸汽冷卻并變成液體狀態(tài)(冷凝),陷阱充滿冷凝水造成杯水車薪,這將打開座椅,讓冷凝水和空氣排出。
