通過控制盤管的過流時間控制末端空間的溫度。開關(guān)式，分常開、常關(guān)兩種。**大口徑為DN25，電壓為220V。采用螺紋連接。應(yīng)設(shè)置Y型過濾器和檢修截止閥。應(yīng)設(shè)置橡膠軟接或金屬軟管。應(yīng)有手動開關(guān)操作裝置。電動兩通動態(tài)平衡閥（一體閥）由動態(tài)平衡閥和電動兩通調(diào)節(jié)閥兩個功能，通過一個閥體實現(xiàn)。優(yōu)點是適用壓差范圍大，調(diào)節(jié)精度較高，體積小。缺點是造價較高。目前鑒于上述問題，很多用戶采取了用自力式平衡閥串連電動兩通調(diào)節(jié)閥的方式來實現(xiàn)一體閥的功能，效果很好，造價降低一半。風(fēng)盤用一體閥意義不大，且由于流量損失大，不經(jīng)濟。電動三通閥分為分流與合流兩種。調(diào)節(jié)性電動三通閥采用AC24V電源，接受并反饋0～10V或4～20mA控制信號，線性調(diào)節(jié)。開關(guān)型驅(qū)動電源為220V?？照{(diào)水系統(tǒng)輔助類閥門倒流防止器用于空調(diào)水補水部分。可以嚴(yán)格防止倒流污染。安裝于飲用水和非飲用水之間。DN50以下采用全銅、不銹鋼螺紋連接，DN65及以上采用球墨鑄鐵閥體，法蘭連接。水錘吸納器由于系統(tǒng)壓力較高或流速較高，因此開閥水錘和停泵水錘都較嚴(yán)重的場合，因此應(yīng)采用活塞式水錘吸納器。水錘吸納器一般安裝于水泵出口止回閥的下游。自動脫氣機采用循環(huán)形式主動去處掉絕大部分溶解在水中的空氣。</p><p> 不宜選用截止閥和閘閥，因為它們的密封面容易被析晶和沉淀物磨損。因此，應(yīng)選用球閥或旋塞閥較合適；也可選平板閘閥，但**好采用夾管閥。在閘閥的選型上，明桿單閘板比暗桿雙閘板適應(yīng)腐蝕性介質(zhì)；單閘板適于粘度大的介質(zhì)；楔式雙閘板對高溫和對密封面變形的適應(yīng)性比楔式單閘板要好，不會出現(xiàn)因溫度變化產(chǎn)生卡現(xiàn)象，特別是比不帶彈性的單閘板優(yōu)越。需要準(zhǔn)確的調(diào)節(jié)小流量時，不宜需要截止閥，應(yīng)采用針型閥或節(jié)流閥。在需要保持閥后的壓力穩(wěn)定時，應(yīng)采用減壓閥。對高壓和超高壓介質(zhì)，常采用直角式截止閥，因為直角式截止閥通常是鍛鋼制作的，鍛鋼的耐壓能力相對比鑄鋼強。2.經(jīng)濟合理性對腐蝕性介質(zhì)，如果溫度和壓力不高，應(yīng)盡量采用非金屬閥門；如果溫度和壓力較高，可用襯里閥門，以節(jié)約貴重金屬。在選擇非金屬閥門時，仍應(yīng)考慮經(jīng)濟合理性。例如，在能夠用聚氯乙烯的情況下，就不用聚四氟乙烯，因為聚四氟乙烯比聚氯乙烯的價格要高。對溫度較高、壓力較大的場合，應(yīng)根據(jù)溫壓表，若普通碳素鋼閥門能滿足使用要求，就不宜采用合金鋼閥門，因為合金鋼閥門價格要高得多。對于粘度較大的介質(zhì)，要求有較小的流阻，應(yīng)采用Y型直流式截止閥、閘閥、球閥、旋塞閥等流阻小的閥門。克拉瑪依電動球閥閥門生產(chǎn)商。</p><div
