style="text-indent:25px">減溫減壓裝置可將閥前管路較高的水壓減少至閥后管路所需的水平。減溫減壓裝置普遍用于高層建筑、城市給水管網(wǎng)水壓過高的區(qū)域、礦井及其他場(chǎng)合，以保證給水系統(tǒng)中各用水點(diǎn)獲得適當(dāng)?shù)姆?wù)水壓和流量。鑒于水的漏失率和浪費(fèi)程度幾乎同給水系統(tǒng)的水壓大小成正比，因此減溫減壓裝置具有改善系統(tǒng)運(yùn)行工況和潛在節(jié)水作用，據(jù)統(tǒng)計(jì)其節(jié)水效果約為30％。減溫減壓裝置是氣動(dòng)調(diào)節(jié)的一個(gè)必備配件，主要作用是將氣源的壓力減壓并穩(wěn)定到一個(gè)定值，以便于調(diào)節(jié)閥能夠獲得穩(wěn)定的氣源動(dòng)力用于調(diào)節(jié)控制?；茨蠝p溫減壓裝置定制減溫減壓裝置應(yīng)先測(cè)量閥門扭矩，并且扭矩不得超過要求的扭矩。</p><div

style="text-indent:25px">減溫減壓裝置的作用：(1)調(diào)整汽溫，使鍋爐送出的蒸汽溫度在規(guī)定的范圍內(nèi)。汽輪機(jī)對(duì)蒸汽溫度要求很嚴(yán)格，一般要求比額定汽溫正負(fù)不超過5℃，即汽溫只能允許在10℃范圍內(nèi)波動(dòng)。汽溫超過規(guī)定值，會(huì)使過熱器、蒸汽管道、汽輪機(jī)及閥門等設(shè)備壽命降低，嚴(yán)重時(shí)可使上述設(shè)備損壞。汽溫低于規(guī)定值，會(huì)降低機(jī)組的經(jīng)濟(jì)性。汽溫降低10℃，機(jī)組的經(jīng)濟(jì)性降低0.6%～0.8%。由于影響汽溫的因素很多，為了保持蒸汽溫度在規(guī)定范圍內(nèi)，必須對(duì)蒸汽溫度進(jìn)行調(diào)整。調(diào)整汽溫的方法很多，減溫減壓裝置調(diào)整汽溫是普遍采用的方法。</p><p style="text-indent:25px">減溫減壓裝置主要特點(diǎn)如下： 1）、采用減溫、減壓分體閥結(jié)構(gòu)，使蒸汽先減壓；然后單獨(dú)減溫，分別在不同系統(tǒng)內(nèi)完成，該裝置的長(zhǎng)度提高了運(yùn)行的可靠性，便于壓力、溫度的**調(diào)節(jié)。 2）、減壓系統(tǒng)：采用三種不同結(jié)構(gòu)形式的減壓閥⑴采用直行程籠式減壓閥結(jié)構(gòu)，多用于t≤400℃,P≤2.5MPa，介質(zhì)經(jīng)多個(gè)小孔節(jié)流減壓，閥內(nèi)可設(shè)多級(jí)節(jié)流降壓，增加閥體使用壽命，保護(hù)了閥座及閥體免受沖擊，延長(zhǎng)了閥門的使用壽命，同時(shí)也降低了裝置的噪音 ⑵雙座減壓閥多用于t≤450℃,P≤4.3MPa的常規(guī)減溫減壓裝置。減溫減壓裝置減溫水充分霧化，以達(dá)到較好的減溫效果。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="減溫減壓裝置哪家比較便宜,減溫減壓裝置"
