進口自由浮球式疏水閥,德國TOK疏水閥,進口蒸汽疏水閥
進口自由浮球式疏水閥利用高精度研磨不銹鋼空心浮球在閥腔內(nèi)隨著凝結(jié)水的液位變化開啟或關(guān)閉閥門。該疏水閥的結(jié)構(gòu)比較簡單,主要由浮球和自動排空裝置組成。閥腔內(nèi)*的動作元件——不銹鋼空心浮球,采用高精度研磨工藝制造,整個球面均可做密封面,工作時無集中磨損,使用壽命長 ; 閥腔內(nèi)無易損件,可靠性高。浮球能根據(jù)水位變化而自由調(diào)節(jié)閥孔的開度,能連續(xù)排放凝結(jié)水,過冷度≈0℃,工作效率高,自動排空裝置分為兩種 :(低壓PN25以內(nèi))液囊熱敏元件組成和(過熱蒸汽系統(tǒng))雙金屬片組成。
特征
1、自由浮球式蒸汽疏水閥能拓飽和凝結(jié)水,回執(zhí)設(shè)備內(nèi)不含有水先積聚,從而獲得zui高的加熱效率
2、自由浮球式蒸汽疏水閥蒸汽壓力變化時,不受影響,能連續(xù)工作性能穩(wěn)定
3、自由浮球式蒸汽疏水閥漏汽變幻無常小,采用*研磨工藝制造,浮球精度高,密封性能好
4、自由浮球式蒸汽疏水閥自動排空氣性能好
5、自由浮球式蒸汽疏水閥壽命長,浮球的整個球面都可以做密封面,無集中磨損。
利用浮力原理,浮球根據(jù)凝結(jié)水量的多少,隨水位的變化而作升降,自動調(diào)節(jié)閥座孔的開度,連續(xù)排放凝結(jié)水,當(dāng)凝結(jié)水停止進入時,浮球降的底部,回到關(guān)閉位置,排水停止,由于排水閥座孔總是在凝結(jié)水位以下,形成水封、水、氣自然分離,達到無蒸汽泄漏。
德國托克TOK品牌:進口自由浮球式蒸汽疏水閥結(jié)構(gòu)特點及工作原理:
疏水閥未開始工作時,自由半浮球沉落在發(fā)射管上,當(dāng)疏水處于排水狀態(tài)時,蒸汽經(jīng)過過濾網(wǎng)和發(fā)射管進入閥體,當(dāng)蒸汽體積增加到一定程度時,浮力使半浮球上浮,在蒸汽壓力作用下,半浮球靠向疏水噴咀將其封閉,阻止了蒸汽外逸。當(dāng)大量凝結(jié)水進入閥體時,半浮球內(nèi)蒸汽體積減少,此半浮球在自身重力作用下落,半浮球脫離疏水噴咀,完成了一個工作循環(huán)。繼而周而復(fù)始運動,起動自動排水阻汽的目的。Free semi-ball float steam trap structural characteristics and working principle of:
Trap did not start working, semi-float free in the launch tube on the sink, drain when the drainage in the state, the steam through the filter and the launch tube into the body, when the steam volume to a certain extent, the buoyancy of the semi-float floating in the steam under pressure, semi-hydrophobic nozzle to float their eyes closed, to prevent the steam to escape. When a large number of condensate into the body, the volume of steam within half reduced float, float in this semi-self-gravity drop, semi-float out of the hydrophobic nozzle, to complete a cycle of work. Then the cycle exercise, start automatically drain resistance steam purposes.
