零泄漏，15年免維護：密封環采用25%的碳纖維PTFE25%的碳纖維材質及碟形彈簧加載閥座結構設計，對溫度壓力變化適應能力強。當球閥啟閉次數增加密封面造成磨損或管道壓力不穩定時，閥座后的碟簧機構進行自由補償，保證密封面與球體的緊密配合，確保零泄漏。

可直(zhi)埋(mai)：直(zhi)埋(mai)式焊接球閥可以直(zhi)埋(mai)地下(xia)，不用建高(gao)大的地井(jing)，只需在地面上設(she)(she)置(zhi)淺井(jing)，根據(ju)管道的設(she)(she)計要(yao)求，可以調整閥桿的長短，節省了大量(liang)的工(gong)程時間和(he)施工(gong)成本。

電(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)電(dian)(dian)(dian)(dian)(dian)(dian)壓與電(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)長度(du)(du)(du)成正比。在相同(tong)的電(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)電(dian)(dian)(dian)(dian)(dian)(dian)壓和焊(han)(han)接電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)時，如果選用的焊(han)(han)劑不同(tong)，電(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)空間電(dian)(dian)(dian)(dian)(dian)(dian)場強度(du)(du)(du)不同(tong)，則(ze)電(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)長度(du)(du)(du)不同(tong)。當其他(ta)條件(jian)不變時，電(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)電(dian)(dian)(dian)(dian)(dian)(dian)壓低，熔深大，焊(han)(han)縫(feng)寬(kuan)度(du)(du)(du)窄，易產生熱(re)裂(lie)紋(wen)。電(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)電(dian)(dian)(dian)(dian)(dian)(dian)壓高時，焊(han)(han)縫(feng)寬(kuan)度(du)(du)(du)增加，余高不夠。埋弧(hu)(hu)焊(han)(han)的電(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)電(dian)(dian)(dian)(dian)(dian)(dian)壓是依(yi)據焊(han)(han)接電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)調整(zheng)的，軟密封焊(han)(han)接球閥報價，即一(yi)定焊(han)(han)接電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)要保持一(yi)定的弧(hu)(hu)長才可能保證焊(han)(han)接電(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)的穩定燃燒，所以電(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)電(dian)(dian)(dian)(dian)(dian)(dian)壓一(yi)般為30～33V。

可以通(tong)過(guo)測(ce)(ce)試(shi)埋地式(shi)全(quan)焊(han)接(jie)(jie)(jie)球(qiu)閥(fa)的嚴密(mi)性，來檢驗其質量(liang)，具體(ti)操作如(ru)下(xia)：首先，蘇州軟密(mi)封焊(han)接(jie)(jie)(jie)球(qiu)閥(fa)，將球(qiu)體(ti)關閉(bi)，然后從袖管(guan)(guan)上試(shi)壓閥(fa)門向球(qiu)閥(fa)內(nei)(nei)注入氮氣(qi)，直到壓力升至(zhi)球(qiu)閥(fa)公稱壓力的1.1倍，緊接(jie)(jie)(jie)著中(zhong)腔放壓閥(fa)接(jie)(jie)(jie)軟管(guan)(guan)通(tong)人盛(sheng)水容器進行檢測(ce)(ce)，軟密(mi)封焊(han)接(jie)(jie)(jie)球(qiu)閥(fa)品(pin)牌，插入深度為1cm，如(ru)果五分鐘內(nei)(nei)沒(mei)有氣(qi)泡產(chan)生(sheng)，軟密(mi)封焊(han)接(jie)(jie)(jie)球(qiu)閥(fa)批發，那么產(chan)品(pin)是合格(ge)的。
