I-valve yebhola luhlobo oluqhelekileyo lwevalve, kwaye uyilo lwayo lwesakhiwo luchaphazela ngokuthe ngqo ukusebenza kwayo kunye nesiphumo sesicelo. Eli nqaku liza kuhlalutya uyilo lwesakhiwo sevalve yebhola kuwe, ukuze ukwazi ukuqonda ngokunzulu iinkcukacha zevalve yebhola.
Amacandelo aphambili kunye nemisebenzi yevalve yebhola
Ivalve yebhola yenziwe ikakhulu ngumzimba wevalvu, ibhola, isiqu sevalve, umsesane wokutywina kunye namanye amacandelo. Icandelo ngalinye lidlala indima ebalulekileyo kwinkqubo yokusebenza ye-valve yebhola, kwaye ngokudibeneyo iqinisekisa ukusebenza kokutywinwa kunye nokusebenza komsebenzi we-valve yebhola.
1. Umzimba wevalvu: Umzimba wevalvu sesona sakhiwo sixhasayo sevalve yebhola, enoxanduva lokudibanisa umbhobho kunye nokuthwala ibhola, isiqu sevalvu kunye namanye amalungu. Izinto eziphathekayo kunye nodonga lomzimba we-valve zikhethwa ngokweemeko zokusebenza kunye neemfuno zesicelo.
2. Ibhola: Ibhola yinxalenye ephambili yevalve yebhola, enoxanduva lokuvula nokuvalwa kwevalve. Umphezulu webhola udla ngokugudiswa ukunciphisa ukukhuhlana kunye nokuphucula ukusebenza kokutywinwa. Izinto eziphathekayo kunye nobukhulu be-sphere zikhethwa ngokweemfuno zemeko yokusebenza.
3. I-valve stem: I-valve stem idibanisa ibhola kunye neendawo zokusebenza, ezijongene nokudlulisa amandla okusebenza. Izinto eziphathekayo kunye neemfuno zamandla ze-valve stem ziphezulu ukumelana noxinzelelo oluhlukeneyo ngexesha lokusebenza.
4. Umsesane wokutywina: Umsesane wokutywina yeyona nto iphambili ekusebenzeni kokutywinwa kwevalve yebhola. Izinto eziphathekayo kunye nohlobo lwendandatho yokutywina zikhethwa ngokweempawu zendlela ephakathi kunye neemfuno zokutywinwa ukuqinisekisa ukusebenza kokutywinwa kwevalve.
Ezimbini, iingongoma zoyilo lwesakhiwo sevalvu yebhola
1. Tshatisa ibhola kunye nesitulo
Ukusebenza kokutywinwa kwevalve yebhola ikakhulu kuxhomekeke kumdlalo webhola kunye nesihlalo. Kuyilo, kufuneka kuqinisekiswe ukuba indawo yoqhagamshelwano phakathi kwebhola kunye nesihlalo ihamba kakuhle kwaye ayinxibi ukuphucula ukusebenza kokutywinwa. Ngexesha elifanayo, ukucocwa phakathi kwebhola kunye nesihlalo kufuneka kulawulwe phakathi koluhlu oluthile lokunciphisa ukuvuza kunye nokuqinisekisa ukuzinza kokusebenza.
2. Uyilo lwesiqu sevalvu
Uyilo lwesiqu sevalve luya kuhlangabezana neemfuno zamandla kunye nokumelana nokunxiba. Izinto eziphathekayo ze-valve stem zingakhethwa kwinsimbi engenasici, i-carbon steel, njl., ngokweemeko zokusebenza zangempela kunye neemfuno zesicelo. Isakhiwo se-valve stem sinentonga ejikelezayo, intonga yesikwere, njl., enokuthi ikhethwe ngokwendlela yokusebenza kunye nendawo yokufaka.
3. Uyilo lweringi yokutywina
Uyilo lwendandatho yokutywina kufuneka luqwalasele izinto zalo, ifom kunye nendlela yokufakela. Izinto eziphathekayo zendandatho yokutywina zinokukhetha irabha ye-fluorine, i-polytetrafluoroethylene kunye nezinye izinto ezinokumelana nokugqwesa okulungileyo kunye nokuxhatshazwa kokugqoka. Ifom yekhonkco yokutywina yi-O-ring, i-V-ring, njl., enokuthi ikhethwe ngokweempawu ze-medium kunye neemfuno zokutywinwa.
Okwesithathu, ukulungiswa kwesakhiwo sevalve yebhola
Ukuze kuphuculwe ukusebenza kwe-valve yebhola, isakhiwo se-valve yebhola sinokulungiswa ngexesha loyilo. Ngokomzekelo, isakhiwo sebhola edadayo sisetyenziselwa ukuba ibhola ihlale igcina unxibelelwano oluhle kunye nesihlalo ngexesha lokusebenza; Isakhiwo sokutywinwa se-bidirectional samkelwa ukuphucula ukusebenza kokutywinwa kunye nobomi benkonzo yevalve; Isakhiwo sokutywinwa kwe-wedge samkelwe ukuphucula ukusebenza kokutywinwa kunye nekhono lokuchasa ukunxiba kwevalve.
Iv. Ukuqukumbela
Uyilo lwesakhiwo sevalve yebhola yinto ephambili echaphazela ukusebenza kwayo kunye nesiphumo sokusetyenziswa. Ukuqonda amanqaku oyilo lwesakhiwo kunye nezicwangciso zokuphucula ii-valve zebhola kusinceda ukuba siqonde kakuhle iimpawu zokusebenza kweevalve zebhola kunye nokubonelela ngesikhokelo sokusetyenziswa okusebenzayo. Ndiyathemba ukuba eli nqaku linokukunceda ukuba uqonde iinkcukacha zevalve yebhola.
