Umehluko phakathi kweValvu yensimbi epholiweko nevalvu yensimbi ephosiweko

I. Ikambiso yokukhiqiza

I-Forged Steel Check Valve yenza i-China:

Yenziwe ngendlela yokubumba, i-billet yensimbi iyafuthunyelwa bese kufakwa umfutho (okufana nokushaya ngesando, ukukhipha) ukuyenza, bese kwenziwa ukucubungula ngomtjhini.

Ikambiso yokubumba yenza bona iinhlamvu zensimbi zicwengisiswe begodu isakhiwo sibe siqinileko, ngaphandle kokukhubazeka okufana nama-pore kanye nokufakwa kwe-slag.

Ivalvu yensimbi ephosiweko:

Yenziwe ngendlela yokuphosa, insimbi encibilikileko ithululelwa ngaphakathi kwesikhunta ukuze ipholile begodu ibunjwe, bese isetjenzwa.

Ikambiso yokuphosa ingabanga imiraro efana nama-pore, imigodi yokuncipha nofana isakhiwo esingalinganiko, okutlhogeka bona kwenziwe ngcono ngokusetjenziswa okulandelako.

II. Iimpahla zezinto

Ivalvu yensimbi eyenziwe:

Amandla aphezulu: Ukubumba kuqeda ukukhubazeka kwangaphakathi, begodu amandla womtjhini (ukujamelana nokugandeleleka nokujamelana nokutjhayisana) angcono kunalawo wokuphosa.

Ukujamelana nokugandeleleka okungcono: kulungele ukugandeleleka okukhulu, amazinga womtjhiso aphezulu nofana ubujamo bokusebenza obumbi khulu.

Ukuvala okungcono: Insimbi inesisindo esiphezulu begodu akulula ukuvuza.

Ivalvu yensimbi ephosiweko:

Ukuqina okuphasi: Isakhiwo sokuphosa singaba namaphutha amancani, okwenza bona kube sengozini yokuqhekeka ngaphasi kokugandeleleka okukhulu.

Iindleko eziphasi: zilungele ukukhiqiza ngobunengi bamavalvu anesimo esiyinkimbinkimbi nofana amakhulu.

III. Isakhiwo nobunzima

Ivalvu yensimbi eyenziwe:

Isakhiwo silula, kanengi siyalingana nofana sincani ngendlela eyakhiwe ngayo. Ubunzima obulula (obungaba ma-20% ukuya ku-30% obulula ukudlula amavalvu wensimbi anemfanelo efanako).

Abathengisi be-Cast Iron Wafer Butterfly Valve China:

Izakhiwo eziyinkimbinkimbi (ezifana namatjhaneli wokugeleza anesimo esikhethekileko, imizimba enemigodi eminengi) ingenziwa. Ubunzima bukhulu begodu ukujiya kweboda kuvamise ukuba bukhulu ukwenza ukutlhayela kwamandla.

IV. Imibandela yokuSebenza esebenzako

Ivalvu yensimbi eyenziwe:

Iinhlelo ezinomfutho omkhulu kanye namazinga womtjhiso aphezulu: njengeziteshi zamandla, amabubulo we-petrochemical, kanye namapayipi we-steam anomfutho omkhulu.

Indawo enezinga lokutjhisa eliphasi: njengeenhlelo zegesi yemvelo (i-LNG), isimbi eyakhiweko inokuqina okungcono kokutjhisa okuphasi.

Iindaba eziyingozi: izinto ezinobuthi, ezivuthako neziqhumako (ngenxa yokuthembeka okuphezulu).

I-China Cast Iron Swing Check Valve:

Ubujamo bokusebenza obujayelekileko obuphakathi nobuphasi: njengokuhlanzwa kwamanzi, amapayipi wamabubulo jikelele, kanye nomtjhiso onomfutho ophasi.

Imidiya yokugqwala: Ukujamelana nokugqwala kungenziwa ngcono ngokufaka izinto ze-alloy (ezifana namavalvu wensimbi engagqwali).

Amavalvu amakhulu: Lokha ikambiso yokubumba ilinganiselwe, ukuphosa kufanele khulu emizimbeni yamavalvu amakhulu.

V. Iindleko nesikhathi sokudiliva

Amavalvu wensimbi enziweko:Iindleko eziphezulu zezinto ezisetjenziswako, ukutjala imali okukhulu ekufezeni amadayi nemitjhini. Umjikelezo wokukhiqiza omude, ofanele amaqoqo amancani nofana iimfuneko ezisezingeni eliphezulu. Ngokuvamileko amanani weyunithi aphezulu.

Amavalvu wensimbi:Iindleko zesikhunta ziphasi, okwenza bona zilungele ukukhiqizwa ngobunengi. Umjikelezo wokukhiqiza mfitjhani, begodu iindleko zincintisana khulu.

VI. Amazinga ajayelekileko namatshwayo

I-China Forged Check Valve:

Iinqophiso: i-ASTM A105 (insimbi yekhabhoni), i-A182 (insimbi engagqwali), njll. Ukutshwaya kuvamise ukufaka hlangana ibizo elithi "Ebunjiweko".

I-Cast Iron Gate Valve:

Iinqophiso: i-ASTM A216 (insimbi yekhabhoni), i-A351 (insimbi engagqwali), njll. Ukutshwaya kuvamise ukufaka ibizo elithi "Cast".
