Umehluko phakathi kwezimpawu ezithambile neziqinile zama-valve:

Okokuqala, kungakhathaliseki ukuthi i-valve yebhola noma i-auvemvane valve, njll., kunezimpawu ezithambile neziqinile, thatha i-valve yebhola njengesibonelo, ukusetshenziswa kwezimpawu ezithambile neziqinile zama-valve ebhola kuhlukile, ikakhulukazi ngesakhiwo, futhi izindinganiso zokukhiqiza ama-valve azihambisani.

Okokuqala, indlela yesakhiwo

Uphawu oluqinile lwe-valve yebhola luwuphawu lwensimbi-kuya-metal, futhi kokubili ibhola lokuvala kanye nesihlalo kuyinsimbi. Ukunemba komshini kanye nenqubo kunzima uma kuqhathaniswa, futhi ngokuvamile kusetshenziswa ukucindezela okukhulu, ngokuvamile okungaphezu kuka-35MPa. Izigxivizo ezithambile ziyizimpawu phakathi kwezinsimbi nezingezona zensimbi, njengenayiloni\PTFE, futhi amazinga okukhiqiza ayafana.

Okwesibili, impahla yokuvala

Isigxivizo esithambile nesiqinile siyinto yokuvala isihlalo se-valve, futhi uphawu oluqinile lwenziwe ngokunemba ngomshini ngempahla yesihlalo se-valve ukuze kuqinisekiswe ukunemba okuhambisanayo ne-valve core (ibhola), ngokuvamile insimbi engagqwali nethusi. Ukuvalwa okuthambile kusho ukuthi impahla yokuvala eshumekwe esihlalweni sevalvu iyimpahla engeyona eyensimbi, ngoba impahla yokuvala ethambile inokunwebeka okuthile, ngakho-ke izidingo zokunemba kokucubungula zizoba phansi kunalezo zokuvala okunzima.

Okwesithathu, inqubo yokukhiqiza

Ngenxa yobuningi bemboni yamakhemikhali, indawo yokusebenza embonini yemishini iyinkimbinkimbi kakhulu, eziningi zinezinga lokushisa eliphezulu nokucindezela okuphezulu, ukumelana nokungqubuzana kwendawo kukhulu, nokugqwala kunamandla, manje ubuchwepheshe buthuthukile, ukusetshenziswa kwezinto ezihlukahlukene kungcono, kanye nokucutshungulwa nezinye izici zingaqhubeka, ukuze i-valve yebhola ene-hard seal ithuthukiswe kabanzi.

Eqinisweni, isimiso se-valve ye-hard seal ball sifana nesophawu oluthambile, kodwa ngenxa yokuthi luwuphawu phakathi kwezinsimbi, kuyadingeka ukucabangela ubuhlobo obuqinile phakathi kwezinsimbi, kanye nezimo zokusebenza, ukuthi iyiphi indlela okufanele uhambe ngayo, njll. Ngokuvamile, ukuqina kuyadingeka, futhi ibhola nesihlalo zihlala ziphansi ukuze kutholakale uphawu. Umjikelezo wokukhiqiza we-valve ye-hard seal ball mude, ukucubungula kuyinkimbinkimbi, futhi akulula ukwenza umsebenzi omuhle we-valve ye-hard seal ball.

Okwesine, izimo zokusetshenziswa

Izigxivizo ezithambile ngokuvamile zingafinyelela izimpawu eziphakeme, kuyilapho izimpawu eziqinile zingaba phezulu noma zibe phansi ngokwezidingo; Izimpawu ezithambile zidinga ukuvikela umlilo, ngoba emazingeni okushisa aphezulu, impahla ye-soft seal izovuza, kuyilapho uphawu oluqinile lungenayo le nkinga; Izigxivizo eziqinile ngokuvamile zingenziwa ngokucindezela okukhulu, kodwa izimpawu ezithambile azikwazi; Ngenxa yenkinga yokugeleza okuphakathi, uphawu oluthambile alukwazi ukusetshenziswa kwezinye izikhathi (njengemithombo yezindaba egqwalayo); I-valve yokugcina eqinile ngokuvamile ibiza kakhulu kune-valve yophawu oluthambile. Ngokuqondene nokukhiqiza, akukho umehluko omkhulu phakathi kokubili, into eyinhloko umehluko phakathi kwezihlalo ze-valve, uphawu oluthambile aluyona insimbi, futhi uphawu oluqinile luyinsimbi.

Okwesihlanu, ekukhethweni kwemishini

Ukukhethwa kwama-valve e-soft and hard seal ball valve ikakhulukazi kusekelwe enkambisweni yenqubo, izinga lokushisa kanye nengcindezi, i-medium ejwayelekile iqukethe izinhlayiya eziqinile noma igugile noma izinga lokushisa lingaphezu kwama-degree angu-200, kuhle ukukhetha izimpawu eziqinile, ububanzi bukhulu kuno-50, umehluko we-valve mkhulu, kanye ne-torque ye-valve yokuvula nayo ibhekwa, futhi i-torque eqinile eqinile lapho ikhethiwe iqinile futhi i-valve ithambile, i-valve kufanele ithambile. izinga lokuvala lingafinyelela ezingeni 6.

Uma unentshisekelo yokuhlala eqinileuvemvane valve, i-valve yesango,I-Y-strainer, i-valve yokulinganisa,hlola i-valve, ungaxhumana nathi nge-whatsapp noma nge-imeyili.
