Ulwazi lwevalvu: amasimi amaninzi aqhelekileyo okusetyenziswa kwevalvu

Kungathiwa iivalvu zinokubonwa kuyo yonke indawo ebomini, nokuba yindlu okanye ngumzi-mveliso, nasiphi na isakhiwo asinakwahlulwa kwivalvu. Okulandelayo,I-Newsway Valve CO.,LTDNdiza kukwazisa amasimi amaninzi aqhelekileyo okusetyenziswa kwevalvu:

1. Iivalvu zokufakelwa kwepetroliyam

①. Isityalo sokucokisa, uninzi lweevalvu ezifunekayo kwisityalo sokucokisa ioyile ziivalvu zepayipi, ikakhulu ivalvu yesango, ivalvu yeglobhu, ivalvu yokujonga, ivalvu yokhuseleko, ivalvu yebhola, ivalvu yebhabhathane, umgibe womphunga, phakathi kwazo, imfuno yevalvu yesango ibandakanya malunga ne-80% yenani lilonke leevalvu, (Ivalvu ibandakanya i-3% ukuya kwi-5% yotyalo-mali lulonke lwesixhobo); ②. Izixhobo zefayibha yekhemikhali, iimveliso zefayibha yekhemikhali ziquka ikakhulu iindidi ezintathu: i-polyester, i-acrylic, kunye ne-vinylon. Ivalvu yebhola kunye nevalvu yejakethi (ivalvu yebhola ejakethiweyo, ivalvu yesango ejakethiweyo, ivalvu yeglobhu ejakethiweyo) yevalvu efunekayo; ③. Isixhobo se-Acrylonitrile. Isixhobo ngokubanzi kufuneka sisebenzise iivalvu eziveliswe ngokwesiqhelo, ikakhulu iivalvu zesango, iivalvu zeglobhu, iivalvu zokujonga, iivalvu zebhola, iitraphu zomphunga, iivalvu zeglobhu yenaliti, kunye neevalvu zeplagi. Phakathi kwazo, iivalvu zesango zimalunga ne-75% yeevalvu zizonke; ④. Isityalo se-ammonia esenziweyo. Ngenxa yokuba ukwenziwa komthombo we-ammonia kunye neendlela zokucoca zahlukile, ukuhamba kwenkqubo kwahlukile, kwaye imisebenzi yobugcisa yeevalvu ezifunekayo nayo yahlukile. Okwangoku, isityalo se-ammonia sasekhaya sidinga kakhuluivalvu yesango, ivalvu yeglobhu, ivalvu yokujonga, umgibe womphunga,ivalvu yebhabhathane, ivalvu yebhola, ivalvu yediaphragm, ivalvu yokulawula, ivalvu yenaliti, ivalvu yokhuseleko, ivalvu yobushushu obuphezulu kunye nevalvu yobushushu obuphantsi;

2. Iivalvu ezisetyenziswa kwizikhululo zamanzi

Ukwakhiwa kwezitishi zamandla kwilizwe lam kuphuhlisa uphuhliso olukhulu, ngoko ke iivalvu zokhuseleko ezinkulu kunye noxinzelelo oluphezulu, iivalvu zokunciphisa uxinzelelo,iivalvu zeglobhu, iivalvu zesango, iivalvu zebhabhathane, iivalvu zokuvala ezingxamisekileyo, iivalvu zokulawula ukuhamba kwamanzi, kunye nezixhobo zokutywina ezingqukuva ziyafuneka. Ivalvu yeglobe, (ngokwe "Isicwangciso seMinyaka emihlanu seshumi" sikazwelonke, ukongeza kumaphondo ase-Inner Mongolia naseGuizhou anokwakha iiyunithi ezingaphezu kwama-200,000 ee-kilowatts, amanye amaphondo kunye nezixeko anokwakha iiyunithi ezingaphezu kwama-300,000 ee-kilowatts);

3. Ivalvu yesicelo seMetallurgical

Kwishishini lesinyithi, ukuziphatha kwe-alumina ngokuyintloko kufuna ivalvu yodaka engagugiyo (ivalvu yokumisa ngaphakathi) kunye nomgibe olawulayo. Ishishini lokwenza intsimbi ngokuyintloko lifuna iivalvu zebhola ezitywiniweyo zesinyithi, iivalvu zebhabhathane kunye neevalvu zebhola ye-oxide, i-stop flash kunye neevalvu ezineendlela ezine;

4. Iivalvu zokusetyenziswa kolwandle

Ngophuhliso lokusetyenziswa kweendawo zeoyile ezikude nolwandle, inani leevalvu ezifunekayo kuphuhliso lweendawo ezithe tyaba zaselwandle liye landa kancinci kancinci. Amaqonga akude nolwandle kufuneka asebenzise iivalvu zebhola ezivaliweyo, iivalvu zokujonga kunye neevalvu ezineendlela ezininzi;

5. Iivalvu zokutya kunye nokusetyenziswa kwamayeza

Iivalvu zebhola zentsimbi engagqwaliyo, iivalvu zebhola zeplastiki ezingeyotyhefu kunye neevalvu zebhabhathane zisetyenziswa kakhulu kweli shishini. Phakathi kweendidi ezili-10 zeemveliso zeevalvu ezingentla, imfuno yeevalvu zenjongo ngokubanzi iphezulu, ezifana neevalvu zezixhobo, iivalvu zeenaliti, iivalvu zeglobhu yeenaliti, iivalvu zesango, iivalvu zeglobhu, iivalvu zokujonga, iivalvu zebhola, kunye neevalvu zebhabhathane;

6. Iivalvu ezisetyenziswa kwizakhiwo zasemaphandleni nasezidolophini

Iivalvu ezinoxinzelelo oluphantsi zihlala zisetyenziswa kwiinkqubo zokwakha ezidolophini, kwaye okwangoku ziphuhliswa kwicala lokukhusela okusingqongileyo nokonga amandla. Iivalvu zerabha ezinobuhlobo nokusingqongileyo, iivalvu zokulinganisela, iivalvu zebhabhathane eziphakathi, kunye neevalvu zebhabhathane ezitywiniweyo ngesinyithi zithatha indawo yeevalvu zesango lesinyithi ezinoxinzelelo oluphantsi kancinci kancinci. Uninzi lweevalvu ezisetyenziswa kwizakhiwo zasezidolophini zasekhaya ziivalvu zokulinganisela, iivalvu zesango ezitywiniweyo ezithambileyo, iivalvu zebhabhathane, njl.njl.;

7. Iivalvu zokufudumeza zasemaphandleni nasezidolophini

Kwinkqubo yokufudumeza yasezidolophini, kufuneka inani elikhulu leevalvu zebhabhathane ezitywiniweyo ngentsimbi, iivalvu zebhalansi ethe tye kunye neevalvu zebhola ezingcwatywe ngqo. Ezi valve zisombulula ingxaki yokungalingani kwe-hydraulic ethe nkqo nethe tye kumbhobho, kwaye zifezekisa ukonga kunye nokuvelisa amandla. Injongo yebhalansi yobushushu.

8. Iivalvu zezicelo zokukhusela okusingqongileyo

Kwiinkqubo zokukhusela okusingqongileyo zasekhaya, inkqubo yokubonelela ngamanzi ifuna kakhulu iivalvu zebhabhathane eziphakathi, iivalvu zesango ezitywiniweyo ezithambileyo, iivalvu zebhola, kunye neevalvu zokukhupha umoya (ezisetyenziselwa ukususa umoya kwipayipi). Inkqubo yokucoca amanzi amdaka ifuna kakhulu ivalvu yesango etywiniweyo ethambileyo kunye nevalvu yebhabhathane;

9. Iivalvu zegesi

Igesi yesixeko ibandakanya i-22% yemarike yendalo yonke, kwaye inani leevalvu likhulu kwaye kukho iintlobo ezininzi. Ngokuyintloko kufuneka ivalvu yebhola, ivalvu yeplagi, ivalvu yokunciphisa uxinzelelo, ivalvu yokhuseleko;

10. Iivalvu zokufaka umbhobho

Iipayipi ezikude ikakhulu zii-oyile eluhlaza, iimveliso ezigqityiweyo kunye neepayipi zendalo. Ezona valve zisetyenziswa kakhulu kwiipayipi ezinjalo ziivalvu zentsimbi ezibunjiweyo ezineenxalenye ezintathu zebhola egcweleyo, iivalvu zesango elisicaba elichasene nesulfur, iivalvu zokhuseleko, kunye neevalvu zokujonga.
