Umehluko phakathi kwezimpawu ezithambile neziqinile zama-valve:

Okokuqala, kungakhathaliseki ukuthi i-ball valve noma i-ivalvu yebhabhathane, njll., kunezimbobo ezithambile neziqinile, thatha ivalvu yebhola njengesibonelo, ukusetshenziswa kwezimbobo ezithambile neziqinile zamavalvu ebhola kuhlukile, ikakhulukazi ngesakhiwo, futhi amazinga okukhiqiza amavalvu awahambisani.

Okokuqala, indlela yokwakha

I-seal eqinile ye-ball valve iyi-seal yensimbi ibe yinsimbi, futhi kokubili ibhola lokuvala kanye nesihlalo kuyinsimbi. Ukunemba kwemishini kanye nenqubo kunzima kakhulu, futhi ngokuvamile isetshenziswa ekucindezelweni okuphezulu, ngokuvamile okungaphezu kuka-35MPa. I-seal ethambile iyi-seal phakathi kwezinsimbi nezingezona izinsimbi, njenge-nylon\PTFE, futhi amazinga okukhiqiza ayafana.

Okwesibili, izinto zokuvala

I-seal ethambile neqinile iyinto yokuvala yesihlalo se-valve, futhi i-seal eqinile ihlanganiswe ngokunemba ngezinto zesihlalo se-valve ukuqinisekisa ukunemba okufana ne-valve core (ibhola), ngokuvamile insimbi engagqwali kanye nethusi. I-seal ethambile isho ukuthi izinto zokuvala ezifakwe esihlalweni se-valve ziyinto engeyona eyensimbi, ngoba izinto zokuvala ezithambile zinokunwebeka okuthile, ngakho-ke izidingo zokunemba kokucubungula zizoba ngaphansi kunezo zokuvala eziqinile.

Okwesithathu, inqubo yokukhiqiza

Ngenxa yezimboni eziningi zamakhemikhali, indawo yokusebenza yemboni yemishini iyinkimbinkimbi kakhulu, eminingi yayo inokushisa okuphezulu kanye nokucindezela okuphezulu, ukumelana kokungqubuzana kwento ephakathi nendawo kukhulu, futhi ukugqwala kunamandla, manje ubuchwepheshe buthuthukile, ukusetshenziswa kwezinto ezahlukahlukene kungcono, futhi ukucubungula nezinye izici kungaqhubeka, ukuze i-valve yebhola enophawu oluqinile ikhuthazwe kabanzi.

Eqinisweni, isimiso se-hard seal ball valve sifana neso seal ethambile, kodwa ngoba siyisivalo phakathi kwezinsimbi, kubalulekile ukucabangela ubudlelwano bobulukhuni phakathi kwezinsimbi, kanye nezimo zokusebenza, ukuthi iyiphi indlela okufanele isetshenziswe, njll. Ngokuvamile, ukuqina kuyadingeka, futhi ibhola nesihlalo kuhlala kugaywa ukuze kufezwe isivalo. Umjikelezo wokukhiqiza we-hard seal ball valve mude, ukucubungula kuyinkimbinkimbi kakhulu, futhi akulula ukwenza umsebenzi omuhle we-hard seal ball valve.

Okwesine, izimo zokusebenzisa

Izivalo ezithambile ngokuvamile zingafinyelela izivalo eziphakeme, kuyilapho izivalo eziqinile zingaba phezulu noma phansi ngokwezidingo; Izivalo ezithambile kudingeka zingashi, ngoba emazingeni okushisa aphezulu, izinto zokuvala ezithambile zizovuza, kuyilapho uphawu oluqinile lungenalo le nkinga; Izivalo eziqinile ngokuvamile zingenziwa ngokucindezela okuphezulu, kodwa izivalo ezithambile azikwazi; Ngenxa yenkinga yokugeleza okuphakathi, uphawu oluthambile alukwazi ukusetshenziswa kwezinye izikhathi (njengezinye izinto ezilimazayo); Ivalvu yokugcina yokuvala eqinile ngokuvamile ibiza kakhulu kunevalvu yokuvala ethambile. Ngokuphathelene nokukhiqiza, akukho mehluko omkhulu phakathi kwalokhu okubili, into eyinhloko umehluko phakathi kwezihlalo zevalvu, uphawu oluthambile aluyona insimbi, kanti uphawu oluqinile luyinsimbi.

Okwesihlanu, ekukhetheni imishini

Ukukhethwa kwama-valve ebhola okuvala athambile naqinile kusekelwe kakhulu ku-medium yenqubo, izinga lokushisa kanye nengcindezi, i-medium ejwayelekile iqukethe izinhlayiya eziqinile noma igugile noma izinga lokushisa liphakeme kunama-degrees angu-200, kuhle ukukhetha ama-hard seal, ububanzi bukhulu kuno-50, umehluko wokucindezela kwe-valve mkhulu, kanye ne-torque ye-valve yokuvula nayo iyacatshangelwa, futhi i-valve yebhola yokuvala eqinile ehleliwe kufanele ikhethwe lapho i-torque inkulu, kungakhathaliseki ukuthi ama-soft seal athambile naqinile, izinga lokuvala lingafinyelela ezingeni lesi-6.

Uma unesifiso sokuthola isihlalo esiqinileivalvu yebhabhathane, ivalvu yesango,Isihluzo se-Y, ivalvu yokulinganisela,ivalvu yokuhlola, ungaxhumana nathi nge-whatsapp noma nge-imeyili.
