style="text-indent:25px">暖通是建筑的一個(gè)組成部分。包括：采暖、通風(fēng)、空氣調(diào)節(jié)這三個(gè)方面，從功能上說也是未來家庭必不可缺的一部分。采暖又稱供暖，按需要給建筑物供給負(fù)荷，保證室內(nèi)溫度按人們要求持續(xù)高于外界環(huán)境。通常用散熱器等。通風(fēng)：向房間送入，或由房間排出空氣的過程。利用室外空氣(稱新鮮空氣或新風(fēng))來置換建筑物內(nèi)的空氣(稱室內(nèi)空氣)，通常分自然通風(fēng)和機(jī)械通風(fēng)?？諝庹{(diào)節(jié)：簡(jiǎn)稱空調(diào)，用來對(duì)房間或空間內(nèi)的溫度、濕度、潔凈度和空氣流動(dòng)速度進(jìn)行調(diào)節(jié)，并提供足夠量的新鮮空氣的建筑環(huán)境控制系統(tǒng)。</p><p> 閥的接口包括入口、出口和排氣口，但不包括控制口。常見的閥有兩通、三通、四通、五通。（1）、二位二通換向閥原理：它是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理，當(dāng)入口與出口沒有壓差時(shí)，通電后，電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起，閥門打開。當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí)，通電后，電磁力先導(dǎo)小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開；斷電時(shí)，先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件，向下移動(dòng)，使閥門關(guān)閉。（2）二位四通換向閥二位四通換向閥是一種采用直流電機(jī)驅(qū)動(dòng)閥芯移動(dòng)，以開閉供油管道或轉(zhuǎn)換供油方向的一種集成化的換向控制裝置；即使在惡劣的工作條件下（如低溫或高粘度油脂），動(dòng)作仍相當(dāng)可靠。該閥適用于公稱壓力為40MPa以下的干、稀油集中潤(rùn)滑系統(tǒng)以及液壓系統(tǒng)的主支管路中，同時(shí)也可作二位四通，二位三通和二位二通三種型式使用。（3）三位四通換向閥三位四通換向閥：是指閥有三個(gè)工作位狀態(tài)，有四個(gè)油口（一般兩進(jìn)兩出），分別用P、T、A、B表示，P為進(jìn)油口，T為回油口、A\B分別接執(zhí)行元件的上下兩腔，閥自然位置時(shí)在中位。閥的結(jié)構(gòu)可見示意圖根據(jù)換向方式分不同可分為：電磁式、電液式、手動(dòng)式三種。工作原理如下：。整體包膠：閘門采用整體包膠，其良好的覆蓋性能與精確的幾何尺寸，保證密封可靠，壽命長(zhǎng)。</p><div
