低溫及高溫場(chǎng)合的動(dòng)態(tài)密封作業(yè)要求，這類密封注劑多制成棒狀固體或雙組分的膩狀材料，將其裝在高壓注***后，在一定的壓力下具有良好的注射工藝性及填充性，且不失去閥門開關(guān)功能。下面介紹兩種常用方法：(1)對(duì)于閥門填料函的壁厚大于8mm左右時(shí)，在動(dòng)態(tài)條件下采用注式帶壓堵漏消除缺點(diǎn)時(shí)，可以直接在閥門的填料函壁面上開設(shè)注劑孔的方式作業(yè)，密封腔就是閥門的填料函自身，注入到閥門填料函內(nèi)的密封注劑的作用與填料所起的作用相同。首先在閥門填料函外壁的適當(dāng)位置用直徑，孔不能鉆透，大約留1--3mm左右，撤出鉆頭，用M12或M10的絲錐攻絲，攻絲結(jié)束后，把注劑專用旋塞閥擰上，并使之處于開的位置，用直徑3mm的長(zhǎng)桿鉆頭把余下的閥門填料函壁鉆透，這時(shí)泄漏介質(zhì)會(huì)沿著鉆頭排削去方向噴出，為了防止鉆孔時(shí)高溫，高壓，0或腐蝕性強(qiáng)的介質(zhì)噴出傷人，鉆小孔前可采用一擋板，先在擋板上用鉆頭鉆一個(gè)直徑5mm的孔，使之能套過(guò)長(zhǎng)鉆頭上，加上擋板鉆余下的壁厚則不會(huì)有危險(xiǎn)。鉆透小孔后取出鉆頭，把注劑專用旋塞閥擰到關(guān)的位置，切斷介質(zhì)連接高壓注劑***進(jìn)行注射密封注劑的操作。如果閥門填料函內(nèi)介質(zhì)壓力低，也可以用直徑3mm的長(zhǎng)鉆頭直接鉆透小孔，再進(jìn)行密封注劑操作作業(yè)?；瓷蠀^(qū)分流閥門廠家溝槽軟密封閘閥重量輕，本體采用_球墨鑄鐵制成，重量較傳統(tǒng)閘閥重量減輕約20%-30%，安裝維修方便。</p><div

(一)關(guān)斷閥這類閥門是起開閉作用的。常設(shè)于冷、熱源進(jìn)、出口，設(shè)備進(jìn)、出口，管路分支線(包括立管)上，也可用作放水閥和放氣閥。常見(jiàn)的關(guān)斷閥有閘閥、截止閥、球閥和蝶閥等。閘閥可分為明桿和暗桿、單閘板與雙閘板、楔形閘板與平行閘板等。閘閥關(guān)閉嚴(yán)密性不好，大直徑閘閥開啟困難;沿水流方向閥體尺寸小，流動(dòng)阻力小，閘閥公稱直徑跨度大。截止閥按介質(zhì)流向分直通式、直角式和直流式三種，有明桿和暗桿之分。截止閥的關(guān)閉嚴(yán)密性較閘閥好，閥體長(zhǎng)，流動(dòng)阻力大，比較大公稱直徑為DN200。球閥的閥芯為開孔的圓球。板動(dòng)閥桿使球體開孔正對(duì)管道軸線時(shí)為全開，轉(zhuǎn)90°為全閉。球閥有一定的調(diào)節(jié)性能，關(guān)閉較嚴(yán)密。蝶閥的閥芯為圓形閥板，它可沿垂直管道軸線的立軸轉(zhuǎn)動(dòng)。當(dāng)閥板平面與管子軸線一致時(shí)，為全開;閘板平面與管子軸線垂直時(shí)，為全閉。蝶閥閥體長(zhǎng)度小，流動(dòng)阻力小，比閘閥和截止閥價(jià)格高</p><p>
