Isishwankathelo sevalve yesango lokutywina elithambileyo

Itywina elithambileyoivalve yesango, kwaziwa njengeivalve yesango elilastiki lesihlalo, yincwadana yemigaqoivalveesetyenziselwa ukudibanisa imibhobho yosasazo kunye nokutshintsha kubunjineli bolondolozo lwamanzi. Ubume betywina elithambileyoivalve yesangosinesihlalo, aivalveisigqubuthelo, ipleyiti yesango, isigqubuthelo soxinzelelo, isiqu, ivili lesandla, igasket, kunye neebholiti zangaphakathi ezinehexagonal. Umjelo wevalvu utshizwe ngomgubo we-electrostatic ngaphakathi nangaphandle. Emva kokubhaka kwiziko lobushushu obuphezulu, iqinisekisa ukugudiseka kwayo yonke imbaleki kunye ne-wedge groove ngaphakathi.ivalve yesango, kwaye ikwanika abantu imvakalelo yokujonga umbala ngenkangeleko. Iivalvu zesango lokutywina ezithambileyo zidla ngokuba ziimbalasane eziblowu-blowu zokonga amanzi ngokubanzi. Ukuba kusetyenziswe amagqabantshintshi aBomvu-bomvu asetyenziswa kwimibhobho yomlilo. Kwaye ithandwa kakhulu ngabasebenzisi.Kunokuthiwa itywina elithambileyoivalve yesangosisivalo esenzelwe ukonga amanzi.

Iintlobo kunye nokusetyenziswa kwetywina elithambileyoiivalve zesango:

Njengevalufa eqhelekileyo yokutshintsha kwimibhobho, iivalvu zesango elithambileyo zisetyenziswa ikakhulu kumsebenzi wamanzi, imibhobho yogutyulo, ubunjineli bokuhambisa amanzi kamasipala, ubunjineli bemibhobho yomlilo, kunye nolwelo olungadleki kancinane kunye neegesi kwimibhobho yoshishino. Kwaye inokwenziwa ngokwemeko yokusetyenziswa kwentsimi, njengevalve yesango elithambileyo, intonga emnyama ethambileyo.ivalve yesango, intonga eyandisiweyo ethambileyo itywinaivalve yesango, engcwatywe itywina elithambileyoivalv yesangoe, itywina elithambileyo lombaneivalve yesango, ivalve yesango yokutywina ethambileyo yepneumatic, njl.

Ziziphi iingenelo zetywina elithambileyoiivalve zesango:

1. Uncedo lwetywina elithambileyoiivalve zesangokufuneka kuqala ibe ngokwexabiso layo. Ngokubanzi, uninzi lweendlela ezithambileyo zevalve yesango zisebenzisa i-ductile iron QT450 iyonke.Iindleko zalo mzimba we-valve ziya kuba zifikeleleke kakhulu kunezo zentsimbi kunye nensimbi engenasici.Xa kuthelekiswa nokuthengwa okukhulu kweprojekthi, oku kuyafikeleleka, kwaye umgangatho uqinisekisiwe.

2. Emva koko, ngokombono weempawu zokusebenza kwevalve yesango lokutywina elithambileyo, ipleyiti yesango yevalve yesitywina esithambileyo ifakwe irabha elastiki, kwaye ingaphakathi lithatha ubume be-wedge. Ukusebenzisa ukhetho lwesandla esiphezulu-Indlela yevili, isikrufu siyehla ukuze siqhube isango elilastiki ukucinezela ezantsi, elivaleleke kumjelo wangaphakathi weweji.Ngenxa yokuba isango lerabha elastiki linokolulwa kwaye likhutshwe, lifikelela kwisiphumo esihle sokutywinwa.Ke ngoko, isiphumo sokutywinwa kwevalve yesango lokutywina elithambileyo kugcino lwamanzi kunye nemithombo yeendaba engonakalisiyo iyabonakala.

3. Okwesithathu, ngokubhekiselele kugcino lwamva lwevalve yesango lokutywina elithambileyo, uyilo lolwakhiwo lwevalve yesango lokutywina oluthambileyo lulula kwaye lucacile, kulula ukuqhawuka nokulufaka. Xa ivalve isetyenziswa ixesha elide, isango elastiki kwiivalve yesangoiya kutshintshwa rhoqo, kwaye irabha iya kulahlekelwa u-elasticity ekuhambeni kwexesha, okukhokelela ekuvaleni okucolile kunye nokuvuza kwevalve. Ngeli xesha, iingenelo zoyilo lwesakhiwo sevalve yesango elithambileyo liyabonakaliswa.Abasebenzi besondlo banokuvula ngokuthe ngqo kwaye babuyisele ipleyiti yesango ngaphandle kokususa yonkeivalve, egcina ixesha kunye nomsebenzi kwaye igcina izixhobo zabantu kunye nezinto eziphathekayo kwisiza.

Zeziphi izinto ezingeloncedo ngetywina elithambileyoiivalve zesango:

1. Ukuthetha ngeentsilelo zetywina elithambileyoivalve yesango, masiyijonge ngokwembono enenjongo. Eyona ndawo ingundoqo yevalve yesango elithambileyo kukuba isango elilastiki elitywiniweyo elithambileyo linokubuyiselwa kwaye lizaliswe ngokuzenzekelayo. Kulunge ngenene ukusebenzisa ivalve yesango elithambileyo lokutywina kunye nokungangeni komoya kwiigesi ezingadlekiyo kunye nolwelo.

2. Kakade ke, ekubeni kukho izinto eziluncedo nezingeloncedo zokungaphelelanga, ngokwendalo kukho nezinto ezingeloncedo. Ukungalungi kwevalve yesango lokutywina elithambileyo kukuba isango lerabha elastiki alinakusetyenziswa ngokuqhubekayo ngaphezu kwe-80 ° C ubushushu okanye ngamasuntswana aqinileyo kunye nomhlwa, kungenjalo iya kubangela amasango erabha elastiki, ukuguqulwa, umonakalo kunye nokuhlwa, okukhokelela ekuvuzeni kwemibhobho. .Ngoko ke, i-valve yesango elithambileyo ilungele ukusetyenziswa kuphela kwi-non-corrosive, i-particle-free and wear-free media.

Isiphelo:

Ibali letywina elithambileyoivalve yesangoikwalapha. Ngokubhekiselele kwizinto eziluncedo kunye nokungalunganga kwevalve yesango elithambileyo, kubaluleke kakhulu ukuqonda iimpawu, ubushushu, uxinzelelo, kunye nokusetyenziswa kwebala eliphakathi xa ukhetha uhlobo. Ukongeza, iingenelo kunye nokungalunganga kwevalve yesango elithambileyo elikhankanywe kwinqaku lidityaniswe novavanyo olubanzi, kunye nokukhetha okunzulu ngakumbi, ukwenzela ukuba ugweme iinkcukacha ezininzi ezingahoywayo ngexesha lokukhetha, ukwenzela ukuba i-valve Akukho nkxalabo. malunga nokuyisebenzisa.
