1. Uyilo lweSitulo esiKhethekileyo

Ivalvu yebhola edadayo isebenzisa uyilo lwesakhiwo seringi yesitywina esiguquguqukayo. Xa uxinzelelo oluphakathi luphantsi, indawo yoqhagamshelwano lweringi yesitywina kunye nebhola incinci. Ngoko ke umlinganiselo ophezulu wokutywina wenziwa kwindawo apho iringi yesitywina kunye nebhola idibana khona ukuqinisekisa ukutywinwa okuthembekileyo. Xa uxinzelelo oluphakathi luphezulu, indawo yoqhagamshelwano lweringi yesitywina kunye nebhola iba nkulu kunye nokuguquguquka kwe-elastic kweringi yesitywina, ukuze iringi yesitywina ikwazi ukumelana nokutyhalwa okuphezulu okuphakathi ngaphandle kokonakala.

2. Uyilo lweSakhiwo esingatshiyo

Xa kutsha ngexesha lokusetyenziswa kwevalvu, iringi yesihlalo eyenziwe nge-PTFE okanye ezinye izinto ezingezizo ezesinyithi iya kubola okanye yonakale phantsi kobushushu obuphezulu kwaye ibangele ukuvuza okuphezulu. Iringi yesitywina engatshiyo ibekwe phakathi kwebhola nesihlalo ukuze emva kokuba isihlalo sevalvu sitshisiwe, i-medium ityhale ibhola ngokukhawuleza iye kwiringi yesitywina yesinyithi esezantsi ukuze yenze isakhiwo sokuvala isinyithi esincedisayo ukuya kwisinyithi, esinokulawula ngokufanelekileyo ukuvuza kwevalvu. Ukongeza, i-gasket yesitywina se-flange ephakathi yenziwe nge-gasket yesinyithi esinamanxeba, enokuqinisekisa ukutywinwa nokuba kuphantsi kobushushu obuphezulu. Uyilo lwesakhiwo esingatshiyo sevalvu yebhola edadayo luhambelana neemfuno ezikwi-API 607, spi 6FA, BS 6755 kunye neminye imigangatho.

3. Ukutywinwa kweValve Stem okuthembekileyo

Isiqu sinikwe igxalaba ezantsi ukuze lingaphumi yi-medium naphantsi kweemeko ezinzima ezifana nokunyuka koxinzelelo ngaphakathi kwe-valve cavity, ukungaphumeleli kwe-gland plate njl. Ukongeza, ukuze kuthintelwe ukuvuza emva kokuba i-stem packing itshisiwe xa kutsha, i-thrust bearing ibekwa kwindawo apho i-stem shoulder kunye nomzimba zidibana khona ukuze zenze i-reverse seal seal. Amandla okuvala e-reverse seal aya kwanda ngokonyuka koxinzelelo oluphakathi, ukuqinisekisa ukutywinwa kwe-stem okuthembekileyo phantsi koxinzelelo olwahlukeneyo, ukuthintela ukuvuza kunye nokuthintela ukusasazeka kwengozi.

Isiqu samkela isakhiwo sokutywina sohlobo lwe-V. Isixhobo sokutywina sohlobo lwe-V sinokutshintsha ngokufanelekileyo amandla okucinezela kunye namandla aphakathi e-gland abe ngamandla okutywina esiqu.

Ngokweemfuno zomsebenzisi, indlela yokucinezela ukupakisha okulayishwe ngentwasahlobo yediski ingasetyenziswa ukwenza ukutywinwa kokupakisha kwesiqu kuthembeke ngakumbi.

4. Ulwakhiwo oluchasene nokungashukumi

Ivalvu yebhola inesakhiwo esichasene ne-static kwaye isebenzisa isixhobo sokukhupha umbane ongashukumiyo ukwenza ngokuthe ngqo umjelo ongashukumiyo phakathi kwebhola nomzimba okanye ukwenza umjelo ongashukumiyo phakathi kwebhola nomzimba ngesiqu, ukuze ikhuphe umbane ongashukumiyo oveliswa kukungqubana ngexesha lokuvulwa nokuvalwa kwebhola kunye nesihlalo ngepayipi, kuthintelwe umlilo okanye ukuqhuma okunokubangelwa yintlantsi engashukumiyo kunye nokuqinisekisa ukhuseleko lwenkqubo.

5. Ukuthintela ukutshixa nokusetyenziswa gwenxa

Ivalvu yebhola yesandla ingatshixwa ngesitshixo xa ikwindawo evulekileyo okanye evalekileyo ngokupheleleyo. Isixhobo sokubeka esivulekileyo nesivalekileyo esingama-90° esinomngxuma wokutshixa senzelwe ukuthintela ukungasebenzi kakuhle kwevalvu okubangelwa kukusebenza kwesiphatho ngabangasebenziyo, kwaye sinokuthintela nokuvulwa okanye ukuvalwa kwevalvu, okanye ezinye iingozi ezibangelwa kukungcangcazela kwepayipi okanye izinto ezingalindelekanga. Isebenza kakhulu ngakumbi kwizinto ezinokutsha. Isebenza kakhulu ngakumbi kwioyile ezinokutsha neziqhumayo, iikhemikhali kunye nemibhobho yokusebenza yezonyango okanye ityhubhu yasentsimini. Inxalenye esentloko yesiqu efakwe kwisiphatho isebenzisa uyilo oluthe tyaba. Xa ivalvu ivuliwe, isiphatho sihambelana nombhobho, ukuze izibonakaliso zokuvula nokuvala kwevalvu ziqinisekiswe ukuba azinampazamo.
