家用減壓閥
1減壓閥工作原理
減壓閥的基本工作原理是靠閥門內(nèi)流道對水流的局部阻力來降低水壓,在連接閥瓣的薄膜兩側(cè)的進(jìn)出口上可以進(jìn)行壓差調(diào)節(jié),這是傳統(tǒng)減壓閥的基本工作原理。此外,還有其他類型的減壓閥,如定比式減壓閥,是利用閥體中的活塞的水壓進(jìn)行控制的,進(jìn)出口端的減壓比和進(jìn)出口側(cè)活塞的面積成一個(gè)反比。這種閥體內(nèi)沒有彈簧,所以不會有彈簧銹蝕的情況,工作時(shí)能保持平穩(wěn),更受消費(fèi)者的青睞。
2減壓閥符號
減壓閥的符號一般有以下幾種表示情況:
P1 —— 進(jìn)口壓力;
P2—— 出口壓力、出口動壓;
ΔP2Q —— 流量特性偏差;
ΔP2Y —— 壓力特性偏差;
P2j —— 出口靜壓;
ΔP2 —— 出口壓力動靜壓升,ΔP2=P2j-P2;
ΔP —— 動態(tài)減壓差,ΔP=P1-P2;
B —— 減壓比,B= P1/ P2;
t ——介質(zhì)溫度,
K —— 動靜壓比。
3減壓閥作用
減壓閥的作用簡單來說就是將一個(gè)較高的壓力減少到所需要的程度的壓力,從而保護(hù)減壓閥后的部件、設(shè)備不被高壓沖擊損壞,并且同時(shí)也保證出口壓力的穩(wěn)定性。這主要是減壓閥依靠對系統(tǒng)的控制和調(diào)節(jié)來對出口壓力進(jìn)行控制的過程。新型減壓閥的控制方式也許和傳統(tǒng)的不同,但主要作用仍然是在保持出口壓力穩(wěn)定的情況下控制并減輕流體或氣體壓力。
4減壓閥型號
減壓閥從發(fā)明到現(xiàn)在已經(jīng)有了許多種不同的規(guī)格和型號,下面就幾種典型的減壓閥型號做出簡要介紹。
1.0232活塞式減壓閥,這是進(jìn)口減壓閥里號稱最輕便小巧并且性價(jià)比最高的一種減壓閥,它是黃銅鍍鎳的,PN16,出口壓力1-5.5bar是可任意調(diào)節(jié)的,常被用于高樓大廈的支管減壓。
2.0234活塞式減壓閥,這是有雙活接頭的一種安裝簡便的減壓閥,也是任意可調(diào)的,黃銅材質(zhì)。應(yīng)用如上。
3.0226膜片式減壓,這種減壓閥是黃銅材質(zhì),可以接上壓力表,是黃銅為主要材質(zhì)。
4.0204膜片式減壓閥也是由黃銅材質(zhì)做成的,PN40,出口壓力1-7bar任意可調(diào)。一般廣泛的用于精密的設(shè)備上,比如說實(shí)驗(yàn)室。

6架空地板保養(yǎng)
架空地板即防靜電架空地板,是防靜電地板的一種。因架空地板使用環(huán)境比較特殊,所以在使用保養(yǎng)過程中應(yīng)注意以下幾點(diǎn):
(1) 禁用尖銳、鋒刃的器具在架空地板的裝飾面上直接施工操作,防止破壞裝飾面的抗靜電性能和美觀程度;
(2) 在使用過程中禁止人員從高處直接跳落到架空地板上,及在移動物品時(shí)野蠻搬運(yùn)、砸傷架空地板;
(3) 在架空地板上搬運(yùn)物品時(shí)。禁止直接在板面上推動物體,使物體與地面間直接摩擦,造成板面劃傷;
(4) 在搬運(yùn)物品時(shí).應(yīng)用帶有膠輪的推車進(jìn)行搬運(yùn)或物體的輪廓與架空地板之間鋪設(shè)隔離墊.防止板面損傷;
(5) 在架空地板面上放置較重物品時(shí),應(yīng)平穩(wěn)擺設(shè),以免砸傷地板;
(6) 對架空地板下部空間的設(shè)備進(jìn)行使用維護(hù)時(shí),應(yīng)用架空地板吸板器進(jìn)行架空地板安裝,拆裝架空地板要輕拿輕,以免損傷架空地板;
(7) 使用中可用千凈的拖布和抹布保特板面的清潔,注意不要把大量的清潔劑液灑在架空地板上,以免液體流到架空地板下面影響下部的線路及設(shè)備的正常運(yùn)行。
7 水晶吊燈價(jià)格
不同牌子的水晶吊燈價(jià)格不同,為了讓大家了解得更清楚,介紹幾個(gè)目前最受歡迎的品牌,看看這類牌子的產(chǎn)品價(jià)格如何。
1. 倫燈燈飾:該品牌產(chǎn)品價(jià)格較實(shí)惠,小型的水晶吊燈價(jià)格在200元左右,而相對高級點(diǎn)的,則在1000元以上。算是真正性價(jià)比很高的品牌了。
2. 華藝燈飾:該品牌一直堅(jiān)持走優(yōu)質(zhì)專業(yè)路線,所生產(chǎn)的產(chǎn)品價(jià)格較實(shí)惠,家用高檔的水晶燈價(jià)格在3000元左右,購買時(shí)可以參考上網(wǎng)的示價(jià)。
3.艾幫燈飾:該品牌產(chǎn)品分有低、高端,價(jià)格自然也存在高低之分,低端的水晶吊燈,價(jià)格大概是300元,而高檔的差不多都是上千元。另外,燈具的體積和造型也會影響價(jià)格的高低。
4. 華森燈飾:該品牌燈飾的價(jià)格可以說非常實(shí)惠,在質(zhì)量相同的情況下,較與其他品牌華森的要便宜很多。一般這個(gè)牌子下的水晶吊燈價(jià)格都在500元以上,高檔的最少也要1000左右。
5. 奧朵燈飾:小型的奧朵水晶吊燈價(jià)格最少也差不多要300元,高檔些的就更不止了,起碼也得上千元。產(chǎn)品的造型和體積,也讓水晶吊燈的價(jià)格有所差異。
