Impazamo yokuvuza kunye nendlela yokuphelisa emva kokufakelwa kwevalve yebhabhathane ethambileyo kumgca ophakathi

Ukutywinwa kwangaphakathi kweumgca concentric ethambileyo uphawu butterfly valveI-D341X-CL150ithembele kuqhagamshelwano olungenamthungo phakathi kwesihlalo serabha kunye neipleyiti butterfly YD7Z1X-10ZB1, kwaye ivalve inomsebenzi wokutywina weendlela ezimbini. Ukutywinwa kwesiqu sevalvu kuxhomekeke kumphezulu wokutywina we-convex yesitulo serabha kunye ne-O-ring yerabha ukuphelisa unxibelelwano oluthe ngqo phakathi kwendawo ephakathi kunye nesiqu somzimba wevalvu, ukuze kwandiswe ubomi bevalve ngesiseko sokuqinisekisa ukusebenza kokutywinwa.
Yonkeivalve yebhabhathane ethambileyoimveliso eshiya umzi-mveliso wethu iye yavavanywa ukuze kuqinisekiswe ukuba ifanelekile ukuba iwushiye umzi-mveliso.
Kwinkqubo yokuthengisa yokwenyani, ukuvuza kwefektri-ifanelekileivalve yebhabhathane ethambileyo MD371X3-10QBiimveliso emva kokufakwa kumbhobho ngamanye amaxesha kwenzeka, kwaye izizathu zokuvuza kunye nendlela yokuphelisa zishwankathelwa ngolu hlobo lulandelayo:

Okokuqala, itywina langaphakathi liyavuza.
Ezona zizathu ziphambili:
1. Umbhobho awuzange ucocwe phambi kokuba kufakwe isivalo sebhabhathane, nasemva kokufakwa kwevalve yebhabhathane, ukungcola okushiyekileyo kumbhobho kwaguga okanye kwavala iringi yokutywina yebhabhathane kunye nepleyiti yebhabhathane, nto leyo ebangele ukuba kuvuzeke.
2. Ngenxa yokuba umphezulu woqhagamshelwano wokutywina wevalve yebhabhathane ethambileyo umxinwa kakhulu, xa isixhobo sombungu singalungiswanga endaweni, ipleyiti yebhabhathane kunye nendawo yokuvala itywina yevalve yebhabhathane ayikho endaweni, kwaye kukho ukutenxa kancinane. Xa uvavanyo loxinzelelo lwefektri lufanelekile, ukuvuza okuncinci kunokwenzeka xa kufakwe kumbhobho.
3. Emva kokuvuza kwevalve yebhabhathane, indawo yexhwayelo ayithathi manyathelo ophando achanekileyo ukuze kuphendulwe iimeko zikaxakeka, ezikhokelela kumonakalo okanye ukuminxeka kweendawo zevalvu.
Isisombululo(izi)
1. Umbhobho awuhlambulukanga: i-valve ivuleke ngokupheleleyo, ipayipi ihlanjululwe, kwaye i-valve butterfly ivuliwe kwaye ivalwe kathathu ukuya kahlanu ngexesha lokucoca, kwaye ayivalwanga ngokupheleleyo ngeli xesha. Emva kokucoca, i-valve ye-butterfly ivalwe ngokupheleleyo ukuvavanya kunye nokuxazulula iingxaki, ezinokuthi ziphelise iphutha.
2. Ukuba ipleyiti yebhabhathane kunye nendawo yokuvala itywina ayikho kwimeko entle: phinda ulungise igiya yeentshulube kwaye ulungelelanise isikrufu somda weswitshi yegiya yeentshulube ukufikelela kwindawo echanekileyo yokuvala yevalve.
3. Ukuba iinxalenye zonakalisiwe: buyisela iindawo ezisecaleni okanye ubuyele kumzi-mveliso ukuze ulungiswe.
Okwesibini, ubuso be-flange okanye ukuvuza kwetywina eliphezulu.

Ezona zizathu ziphambili:
1. Ukusilela okanye ukuguga komsesane wokutywina werabha wetywina eliphezulu kukhokelela ekuvuzeni kwetywina eliphezulu.
2. Uxinzelelo lombhobho lungaphezulu komda woxinzelelo lokutywinwa kwevalve, okukhokelela ekuvuzeni kwesitywina esingaphezulu.
3. Xa iivelufa butterflyifakelwe, iziko li-asymmetrical, kwaye eliphakathi lingena kwindawo yokudibanisa phakathi komzimba wevalve kunye nesihlalo sevalve, okukhokelela ekuvuzeni kwicala le-flange.
4. I-flange ayikhethwanga ngokufanelekileyo okanye ifakwe, okubangela ukuvuza kwe-flange surface.
Isisombululo(izi)
1. Ukungaphumeleli okanye ukuguga kwamakhonkco okutywina irabha: Imikhono yevalve ye-polymer inokongezwa ngokudibanisa okanye ukubuyisela amakhonkco okutywina.
2. Uxinzelelo ludlula uxinzelelo oluqhelekileyo lweivelufa butterfly: nciphisa uxinzelelo lombhobho okanye utshintshe uhlobo lwevalve enokumelana noxinzelelo.
3. Indawo ephakathi ingena kumphezulu woqhagamshelwano phakathi komzimba wevalve kunye nesihlalo sevalvu: Lungisa i-symmetryembindini wevalve yebhabhathanekwaye utshixe ngokulinganayo ibholithi.
4. Kucetyiswa ukuba usebenzise i-flange ekhethekileyo yevalve yebhabhathane yevalve yebhabhathane ethambileyo, kwaye akukho gasket yentsimbi yeflange efunekayo.
