Uthotho lwevalvu yeBhola edadayo
- I-ARAN inoluhlu lweevalvu zebhola ezidadayo kwiindidi ezahlukeneyo, izixhobo kunye nokubekwa okusemgangathweni olungileyo kunye neendleko ezisebenzayo zokuvalwa kwemibhobho ngokubanzi.Uyilo lohlobo lwebhola edadayo lusebenza kubungakanani obuncinci okanye kwiivalvu zebhola eziphantsi koxinzelelo oluphantsi, inefom yentsimbi ekhuselweyo okanye ephoswe ngentsimbi, ukwakheka komzimba wevalve yee-2 iipcs okanye ezi-3pcs.Xa kuthelekiswa nevalve yebhola yetrunnion, ivalve yebhola edadayo ihlala incinci ivalufa engekho nkulu kune-intshi ezi-6.
- Ukuphela kweFlangeUxinzelelo lwevalve yebhola edadayo ubungakanani obukhoyo:
- 150LBS ubukhulu 1/2IN~8IN,300LBS ubukhulu1/2”~6IN
- 600LBS ubukhulu1/2 IN~3IN,900~1500LBS ubukhulu1/2IN~2IN.
- SW/NPT/BW/NIPPLE isipheloUxinzelelo lwevalve yebhola edadayo ubungakanani obukhoyo
- 150LB ~ 800LBS ubukhulu 1/2IN~2IN.
- 900 ~ 2500LBS ubukhulu 1/2IN~11/2IN.
- Yintoni ivalve yebhola edadayo?
- Ivalve yebhola edadayo ithetha ukuba ibhola idada kuyilo lwegumbi levalvu, isihlalo sizinzileyo emzimbeni, kwaye ibhola ixhaswa sisikhondo.Ukudityaniswa kwesikhondo ngebhola kwintshukumo yekota.Ibhola edadayo phakathi kwezihlalo zevalve kwaye usebenzise umgca woxinzelelo oluphakathi ophakathi ukutyhala ibhola ezantsi komlambo ukuze kuvaleke okuqinisekileyo kunye nevalve itywinwe.Ivalve inokudityaniswa ngendlela ephindwe kabini, kodwa itywina kuphela ezantsi komsinga.
- Yintoni ivalve yebhola edadayo?
- Ibhola edadayo yivalve exineneyo yobungakanani obuncinci kunye nevalve yetorque ephantsi.
- Isixhobo somzimba ivelufa sinentsimbi ekhandiweyo kunye nefom yemathiriyeli yentsimbi, umzimba wevalvu uya kuba ngamaqhekeza amabini okanye amathathu uyilo kunye nomzimba womanyano.
- ● Uyilo oluthembekileyo lwetywina lesihlalo
- Ivalve yebhola edadayo ngokubanzi ithatha isihlalo esithambileyo sokutywina.Xa uxinzelelo oluphakathi lusezantsi, indawo yoqhagamshelwano yomsesane wokutywina kunye nebhola incinci, kodwa isihlalo kunye nomphezulu woqhagamshelwano webhola ufumene umlinganiselo wokutywinwa womgangatho ophezulu wokuqinisekisa ukutywinwa okuqinileyo.Xa uxinzelelo oluphakathi luphezulu, indawo yoqhagamshelwano yetywina kunye nebhola iba ngaphezulu, kwaye umsesane wokutywina wesitulo unokunyamezela ukutyhala okuphakathi ngaphandle kokonakala.
- ●Uyilo lweSakhiwo esingenamlilo kwisitulo, iflange ephakathi kunye nesiqu
- Kwimeko yomlilo, i-ring seat eyenziwe nge-PTFE okanye ezinye izinto ezingezizo zetsimbi ziya kuchithwa okanye zonakaliswe phantsi kobushushu obuphezulu kwaye kubangele ukuvuza okuphezulu.Umsesane wokutywina ongenamlilo ufakwa phakathi kwebhola kunye nesihlalo ukuze emva kokuba isitulo esithambileyo sevalve sitshise, isiphakathi siya kutyhala ibhola ngokukhawuleza ukuya kumsesane wokutywina wesinyithi osezantsi ukwenza intsimbi encedisayo kwisakhiwo sokutywina sesinyithi, esinokulawula ngokufanelekileyo ukuvuza kwevalvu.Ukongeza, i-gasket yokutywina ye-flange ephakathi yenziwe ngentsimbi yenxeba yentsimbi, enokuqinisekisa ukutywinwa naphantsi kobushushu obuphezulu.Uyilo lwesakhiwo somlilo wevalve yebhola edadayo ihambelana neemfuno ze-API 607, API 6FA, BS 6755 kunye ne-JB/T6899 njl.
- Umzobo. Uyilo oluthembekileyo lwesitywina soyilo kunye noyilo lweSakhiwo esingangenwa ngumlilo esitulweni, i-flange ephakathi kunye nesiqu
- ●ISithi seSithi esithembekileyo seValve
- Isiqu sisimo se-T esiyilo lokuchasa ukuvuthela ngaphandle, naxa igumbi levalve phantsi koxinzelelo olungaqhelekanga linyuka kunye nedlala lokupakisha elikhululekileyo, isikhondo sevalvu siyakuchasa ukuvuthela.
- Xa kutshisiwe isikhondo sokupakishwa kwe-thrust, indawo apho igxalaba lesiqu kunye nokudibana nomzimba kwenze isitulo sokuvala umva.Amandla okutywinwa kwetywina elibuyela umva aya kwanda ngokonyuka koxinzelelo oluphakathi, ukuze kuqinisekiswe ukutywinwa kwesiqu esithembekileyo phantsi koxinzelelo olwahlukeneyo, ukuthintela ukuvuza kunye nokuphepha ukusasazeka kwengozi.
- Isiqu samkela uhlobo lwe-V lokupakisha isakhiwo sokutywina, ukupakisha okunjalo kunokutshintsha ngokufanelekileyo uxinzelelo kunye namandla aphakathi kwedlala kumandla okutywinwa kwesiqu.
- Ngokweemfuno zomsebenzisi, i-disc spring elayishwe ukupakisha indlela yokucofa inokwamkelwa ukwenza ukutywinwa kokupakishwa kwesikhondo kuthembeke ngakumbi.
- ●Ulwakhiwo lwe-Anti-static
- Ivalve yebhola ibonelelwa nge-anti-static structure.Kubukhulu obungaphantsi kwe-DN25 nangaphezulu kwe-DN25 sebenzisa uyilo olwahlukileyo lwe-anti-static spring phakathi kwesiqu, umzimba kunye nebhola ukhulula umbane ongashukumiyo uthintela umlilo okanye ugqabhuko-dubulo.
- ● Isixhobo sokutshixa ivalvu
- Isixhobo sokutshixa ivalve siyafuneka kwiziza ezikhethekileyo ezibalulekileyo apho kuthintelwa ukusebenza kwempazamo yevalve yokukhusela umbhobho.
- Umzobo. IBhola iSakhiwo esiAnti-static kunye neFig. isixhobo sokutshixa ivalvu
