Isicelo: Qhagamshela kwaye unqumle i-medium;thintela umva we-medium;lungisa uxinzelelo kunye nokuhamba kwe-medium;ahlula, axube okanye asasaze isiphakathi;thintela uxinzelelo oluphakathi ekugqithiseni ixabiso elichaziweyo kwaye uqinisekise ukusebenza okukhuselekileyo kombhobho okanye izixhobo.
Imidiya esebenzayo: umphunga, amanzi, ioli;isisombululo sekhemikhali;
Zimbini iindidi zokutywina zevalve yebhola: itywina elithambileyo kunye netywina eliqinileyo;
Iindlela ezintathu zokuxhuma: i-flange;umsontoukuwelda
Ubushushu bokusebenzisa: -196 ukuya kuma-350 degrees
Imo yokusebenza: manual;umoyaumbanehydraulic
Umahluko phakathi kwevalve yebhola eneqhekeza elinye, ivalve yebhola enamacandelo amabini kunye nevalve yebhola enamacandelo amathathu:
Ivalve yebhola ejijwayo enentambo yangaphakathi yohlulwe ibe yivalve yebhola eneqhekeza elinye, ivalve yebhola enamacandelo amabini kunye nevalve yebhola enamacandelo amathathu ngokwesakhiwo sayo.Ukuqonda iimpawu zabo kunye nokungafani kuya kusinceda sikhethe i-valve yebhola efanelekileyo yokusetyenziswa.
Okokuqala, masiqale siqonde ukuba yintoni ivalve yebhola eneqhekeza elinye, ivalve yebhola enamacandelo amabini kunye nevalve yebhola enamacandelo amathathu ngokwenkcazo.
Ivalve yebhola enye ibhekisa kwivalve yebhola edityaniswe ngomsonto omncinci wobubanzi obungaphakathi kwaye yenziwe ngumzimba wevalve yesiqwenga esinye.Umzimba wevalvu edibeneyo uhlala usetyenziselwa iivalvu ezinobungakanani obuncinci.
Ivalve yebhola eneziqwenga ezibini, ekwabizwa ngokuba yivalve yebhola enamacala amabini, ibhekisa kwivalve edityaniswe nentambo yangaphakathi enobubanzi obuncinci, umzimba wevalve wahlulwe ube ngamacandelo amabini, kwaye ifom ye-buckle idla ngokusetyenziswa.
Ivalve yebhola eneziqwenga ezintathu idityaniswe ngomsonto wangaphakathi, kwaye umzimba wevalve unamacandelo amathathu.Ngokuqhelekileyo isetyenziselwa iivalve ezinkulu kunye nezibaluleke ngakumbi.
Umahluko kunye neempawu zabo zinokucazululwa kule miba ilandelayo:
1. Ukwahlula kwisakhiwo
Ivalve yebhola enye yi-piece-piece, eyenziwe ngebhola, i-PTFE ring, kunye ne-lock nut.Ububanzi bebhola buncinci kancinci kunobubanzi bombhobho, bufana nevalve yebhola ebanzi.Iinkcukacha, ukuhamba kuncinci.
Ivalve yebhola enamacandelo amabini yenziwe ngamacandelo amabini, kwaye isiphumo sokutywinwa singcono kuneso siqhekeza esinye sebhola.Idayamitha yebhola iyafana naleyo yombhobho, kwaye kulula ukuyiqhaqha kunevalve yebhola enye.
Ivalve yebhola eneziqwenga ezintathu yenziwe ngamalungu amathathu, isigqubuthelo sevalvu kumacala omabini kunye nomzimba wevalvu ephakathi.Umahluko phakathi kwevalve yebhola enamacandelo amathathu kunye nevalve yebhola enamacandelo amabini kunye nevalve yebhola enye kukuba kulula ukuyiqhaqha kunye nokugcina.Ukumelana noxinzelelo olunamandla.
2. Yahlula kuxinzelelo
Ukunyanzeliswa koxinzelelo lwe-valve yebhola yebhola emithathu kuphezulu kakhulu kunomnye kunye neentsimbi ezimbini zebhola.Icala langaphandle le-valve yebhola yebhola emithathu engundoqo igxininiswe ngeebholiti ezine, ezidlala indima enhle kakhulu yokuqinisa.Umzimba wevalve yokuphosa echanekileyo unokufikelela kuxinzelelo lwe-1000psi≈6.9MPa.Uxinzelelo oluphezulu lufuna imizimba yevalvu eyenziwe ngomgunyathi.
3. Ukwahlula ngokwembono yezoqoqosho
Ngenxa yokuba izinto eziphambili zevalve yebhola enye ingaphantsi kunezinye iindidi ezimbini, ixabiso lihle, kwaye liyafana nevalve yebhola ebanzi.Ixabiso le-valve yebhola ephindwe kabini liphezulu kunelo lohlobo olulodwa.Uhlobo lweziqwenga ezintathu luqulunqwe ngamacandelo amathathu ngenxa yokumelana noxinzelelo oluphezulu.Izinto eziphathekayo ziphezulu kunezinye iindidi ezimbini.Ixabiso liphezulu kuneziqwenga ezimbini kunye neevalve zebhola enye.
