按閥門類別分為：閘閥：是作為截止介質(zhì)使用，優(yōu)點(diǎn)是閥芯可以全部打開，此時(shí)介質(zhì)運(yùn)行的壓力損失**小。閘閥通常適用于不需要經(jīng)常啟閉，適用保持閘板全開或全閉的工況。不適用于作為調(diào)節(jié)或節(jié)流使用。常用閘閥類型如：楔式閘閥、平行式閘閥、平行雙閘板閘閥、楔式雙閘板閘等。**常用的形式是楔式閘閥和平行式。連接方式為絲扣連接和法蘭連接；用于采暖、工藝管道系統(tǒng)，連接方式隨管道連接方式；≥dn50給水、煤氣管道上采用法蘭閘閥，截止閥：截止閥的閥桿軸線與閥座密封面垂直。閥桿開啟或關(guān)閉行程相對較短，并具有非?？煽康那袛鄤幼鳎沟眠@種閥門非常適合作為介質(zhì)的切斷或調(diào)節(jié)及節(jié)流使用；介質(zhì)通過此類閥門時(shí)的流動方向發(fā)生了變化，因此截止閥的流動阻力較高于其它閥門。常用的截止閥有以下幾種：角式截止閥，常用于衛(wèi)生器具控制閥。直通式截止閥，常用于給水系統(tǒng)柱塞式截止閥：主要用于要求快速“開”或“關(guān)”系統(tǒng)連接方式為絲扣連接，法蘭連接；用于蒸汽系統(tǒng)，連接方式隨管道連接方式；≤DN50給水系統(tǒng)采用絲接，大于≥采用法蘭連接。截止閥的優(yōu)點(diǎn)，云南光學(xué)暖通設(shè)備安裝服務(wù)提供，云南光學(xué)暖通設(shè)備安裝服務(wù)提供，密閉性好。球閥：球閥是由旋塞閥演變而來。它具有相同的旋轉(zhuǎn)90度提動作，云南光學(xué)暖通設(shè)備安裝服務(wù)提供，不同的是旋塞體是球體。醫(yī)院潔凈區(qū)壓差調(diào)節(jié)。云南光學(xué)暖通設(shè)備安裝服務(wù)提供</p><div

消火栓箱體安裝時(shí)要考慮裝飾層的厚度；應(yīng)保證箱體安裝高度正確，一般箱底安裝高度為；若帶自救式卷盤，箱底為；（3）設(shè)于磚墻上的暗裝消火栓箱體上部應(yīng)采取承重措施，以防止箱體受壓變形而影響箱門的開啟；（4）按照消防要求，應(yīng)將栓口接管與箱底留孔間隙處進(jìn)行防火封堵；箱體背板不得外露于墻面，如箱體所在的墻面厚度小于箱體厚度，應(yīng)采用防火材料對箱體背板后面進(jìn)行處理，且處理后不應(yīng)低于同房間耐火等級；（5）消火栓箱內(nèi)的栓、水槍、水龍帶及快速接扣必須按設(shè)計(jì)規(guī)格配置齊全，其產(chǎn)品必須符合消防部門批準(zhǔn)生產(chǎn)、銷售、使用的合格品。水龍帶與快遞接扣一般采用16號銅絲（）纏繞2～3道，每道纏緊3～4圈，扎緊后將水龍帶和水槍掛于箱內(nèi)掛架或卷盤上。：（1）栓口應(yīng)朝外，并不應(yīng)安裝在門軸側(cè)；（2）栓口中心距地面為，允許偏差€mm；（3）閥門中心距箱體側(cè)面為140mm，距箱后內(nèi)表面為100mm，允許偏差€；（4）消火栓箱體安裝的垂直度允許偏差3mm。，坡向合理，不得倒坡。（1）安裝前先按照確定的衛(wèi)生器具安裝尺寸修整孔洞。根據(jù)圖紙要求并結(jié)合實(shí)際情況，按修整后孔洞位置測量尺寸，繪制加工草圖，根據(jù)草圖量好管道尺寸，進(jìn)行裁管、預(yù)制，排水橫管變徑時(shí)應(yīng)保證管頂平接；。</p><p> 3）開口分布不合理或是開口沒有隨著與主管道的距離增大而增大，從而引起局部排煙不通暢；4）集氣（煙）罩上面的集煙管道截面積太小，導(dǎo)致出煙不通暢。5排煙管道廚房排煙管道的水平段不宜太長，一般水平**遠(yuǎn)距離不應(yīng)超過15m并且要有2%以上的坡度，水平末端設(shè)活接頭，以方便清理油垢。排風(fēng)速度按規(guī)范不得低于10m/s，以防風(fēng)速過低使油附著于煙道上，接排風(fēng)罩的支管應(yīng)設(shè)風(fēng)量調(diào)節(jié)閥。排煙管道的設(shè)計(jì)和安裝不合理，往往會造成廚房排煙不通暢，直接影響油煙凈化器的使用。其主要原因有以下幾種：（1）主排煙管道通風(fēng)面積不夠，氣體流速過大。根據(jù)工程經(jīng)驗(yàn)，排煙主管道內(nèi)風(fēng)速不能超過15m/s。否則在運(yùn)行一個(gè)時(shí)期以后（如一年以后）很容易造成排煙系統(tǒng)不通暢。在油煙凈化器的運(yùn)行實(shí)踐中，大部分案例都是因排煙管道通風(fēng)面積不足引起的不通暢，管道內(nèi)氣體的流速都在15m/s以上。（2）排煙管道由于要穿過建筑梁而使管道通風(fēng)截面積變小，截面上阻力增加，造成氣流不通暢。（3）排煙管道在穿過建筑梁或躲避其它設(shè)備管道時(shí)，排煙管道中的一段會低于整體排煙管道平面。在使用一段時(shí)間后，由于油水混合物會積聚在較低的那段排煙管道中，直接影響排煙通暢。。實(shí)驗(yàn)室暖通設(shè)備安裝工程。</p><div
