Ingasetshenziswa uma kwenzeka ukugeleza kwe-medium okunezindlela ezimbili. Akukho ukuqondiswa.
Indawo yokuvala akulula ukuyiguguleka uma ivuliwe ngokuphelele. Ubude besakhiwo bufushane. Akufanele kuphela ama-valve amancane, kodwa futhi kufanelekile ama-valve amakhulu. . Elinye uhlobo lwenduku eveziwe, kanti i-valve yesango ihlukaniswe izinhlobo ezimbili ngokwentambo yesiqu. Elesibili uhlobo lwenduku emnyama. Ngokwesakhiwo se-ram, ihlukaniswe futhi ngezigaba ezimbili, esinye sihambisana, kanti esinye siyindlela yokusebenza.

Iyini i-valve yesango lesihlalo senjoloba?

I-valve yesango lesihlalo senjoloba,isimiso sokuklama esibaluleke kakhulu uma kukhethwa ukusetshenziswa ezinhlelweni zokusabalalisa.

II-valve yesango lesihlalo senjolobaiqukethe i-wedge ehlanganiswe ngokuphelele nerabha ye-EPDM eboshwe unomphela ku-wedge futhi ihlangana ne-ASTM D249. Umzimba we-valve, i-bonnet, kanye ne-stuffing plate kugqokwe nge-fusion bonded epoxy (FBE), ukubukeka okuhle kanye nokuvikelwa okuhle kakhulu. Ukulungiswa okukhethwa kukho kufaka phakathi i-Non-Rising Stem (NRS) noma i-Outside Screw & Yoke (OS&Y).

I-valve yesango lesihlalo senjolobafuthi ingasebenza nge-Spur noma i-Bevel Gear, kanye ne-actuator kagesi.

Izici eziyinhloko ze-NORTECHI-valve yesango lesihlalo seRubber

Umzimba yenziwe ngensimbi ethambile ngokubumba ngokunemba,Yaklanywa yisofthiwe ye-3D, enokuhlaziywa kwezinto ezilinganiselwe zesakhiwo. I-coefficient yokuphepha ingaphezu kuka-2.5. Isiteshi esiphansi esibushelelezi saklanywa, ukugwema ukuqongelela kokungcola nokuqinisekisa ukumelana okuncane kokugeleza.

IsiquYenziwe ngensimbi engagqwali ngokugingqa. Uhlobo oluhlanganisiwe, igwema ukusebenzisa izindandatho zethusi eziyingxenye ukunciphisa ububanzi besiqu. Isikulufu sohlobo lweladi esiguquliwe esibushelelezi sikhishwe. I-global mirror polish, ifanelana kahle nezindandatho ze-O, ukuqinisekisa ukuthi ukujikeleza okubushelelezi kanye ne-torque encane.

Uhlaka lweigejaYenziwe ngensimbi ethambile ngokubumba isihlabathi esimbozwe kusengaphambili, i-wedge imbozwe yi-EPDM ngokuphelele. Idizayini yesivalo esiphindwe kabili, umugqa ngamunye wesivalo ungasebenza ngokuzimela

Amabhawodi ebanga lesi-8.8 axhumanisaibhonethikanye nomzimba, amabhawodi ayembozwe nge-wax encibilikayo evikela amabhawodi ekugqwaleni. I-gasket ephakathi kwebhonethi nomzimba yenziwe nge-EPDM. Isembozo se-valve sifakwe umsele wokugcina, qiniseka ukuthi i-gasket yerabha ngeke ikhishwe ngaphansi komfutho wamanzi aphezulu.

Ukukhiqiza okuhambisana nemvelo

Ubuso bangaphakathi nangaphandle bevalvu bumbozwe nge-epoxy powder ehlanzekile yi-fusion bonded epoxy (FBE), ubukhulu obujwayelekile bungaphezu kuka-250um. Ukunamathela kwengubo kuqinile, ngeke kubhujiswe ngaphansi kokuhlolwa kwamandla okushaya kwe-3J. Izingxenye zangaphakathi zingahlangabezana nezidingo zokuvikela imvelo, futhi zingasetshenziswa ngqo emanzini aphuzwayo, ukudla kanye nendawo yemithi. Inqubo yokumboza ngempuphu kagesi ingathembisa amandla aphezulu okunamathela kanye nokumelana nokugqwala okunamandla.

Ukufakwa okulula nokusebenza

Sinikeza izinhlobo ezahlukene zesikhombikubona njengokuxhumeka kwe-flange, isokhethi lepayipi le-PVC, isokhethi lepayipi lensimbi elithambile, ukunciphisa njll. Umklamo wokuxhumeka okhethekile ungenziwa ngokwezifiso ngokwezicelo.

yabasebenzisi.

Ivalvu ingavalwa ngokuphelele futhi ifinyelele lapho ivuza khona nge-torque encane. I-torque yangempela yokusebenza ingu-80% kuphela wobubanzi, futhi amavalvu esango angathwala i-MST ye-3 * DN NM. Imikhiqizo idlule ukuhlolwa kokuphila izikhathi ezingu-5000. Kumavalvu anobubanzi obukhulu, singanikeza amadivayisi okonga abasebenzi, ukuqinisekisa ukuthi wonke amavalvu angavulwa futhi avalwe ngumuntu oyedwa. Isondo lesandla liqinile, linobukhulu obunembile, lihambisana kahle nesiqu sevalvu, ukuma kwalo kuhambisana nobuchwepheshe bomuntu, ukuqinisekisa ukusebenza okulula.

ukusebenza - Amavalvu esango ahlala phansi aqinile

Ukulungiswa okulula

Indandatho yokuvala ingashintshwa ngaphandle kokunqamula amanzi, kulula ukuyilungisa futhi kunciphisa isikhathi sokulungisa ngangokunokwenzeka. Ukungqubuzana okuncane kakhulu phakathi kwe-brass bushing kanye ne-"O" seal, kuzoqinisekisa ukuthi indandatho yokuvala ihlala isikhathi eside. I-torque ephezulu yokusebenza ilawulwa.
