Ukuvulwa nokuvalwa kweAMAVAVAVU ESANGO  ivinjiwe, ayiguquki noma ayikwazi ukuvula nokuvala ngokujwayelekile, noma ayikwazi ngisho ukuqhubeka nokuvula nokuvala, ikakhulukazi ngenxa ye-jam phakathi kwesiqu se-valve nezinye izingxenye, ikakhulukazi ujamu phakathi kwesiqu se-valve nokupakisha.Ngokuvamile

Indlala yokupakisha iyachezuka futhi ishaye isiqu se-valve

Indlela yokwelapha: faka ngendlela efanele

Ukupakisha kufakwe ngokungalungile noma kuminyene kakhulu

Indlela yokwelapha: qinisa ngaphambili isigcwalisi bese ukhulula isigcwalisi ngendlela efanele.

Isiqu kanye nokupakisha i-gland bite

Indlela yokwelapha: buyisela noma lungisa.

Ukuluma noma ukulunywa phakathi kwezingxenye

Indlela yokwelapha: Gcoba isiqu se-valve ngendlela efanele.

Ukuklwebheka endaweni yokuvala i-valve, ukuklwebheka okuluma kukholamu ekhanyayo yesiqu se-valve kanye nokuklwebheka engxenyeni ecushiwe yesiqu se-valve, njll. Ngemva kokuba indawo yokuvala isigayiwe, kunezinhlamvu ezilumayo ezishunyekwe endaweni yokuvala, kodwa ayihlanzwa, okwenza ukuthi ukuvala uphawu kuklwejwe;ngemva kokusetshenziswa okuthile, izinhlamvu ezihlabayo zikhishwa ngaphansi kokuguguleka kwe-medium futhi zinamathele endaweni yokuvala.I-valve ivuliwe futhi ivaliwe.Ibanga imihuzuko.

Indlela yokwelapha: Sebenzisa ama-abrasives ngokunengqondo, futhi uhlanze indawo yokuvala ngemva kokugaya.

Ukungcola noma i-welding slag phakathi nendawo ayihlanzwa, ibangele imihuzuko.

Indlela yokwelapha: hlanza futhi.

AMAVAVAVU ESANGOisiqu sihlikihla phezu komkhono wokucindezela ukupakisha kanye nephedi yokupakisha.I-medium equkethe i-boron phakathi izocwebezela ukuze yakhe izinhlayiya eziqinile ngemva kokuba isikhishiwe.Lapho ukupakisha kuthinta isiqu se-valve, ingaphezulu le-valve stem lizocindezelwa lapho ushintsha.

Indlela yokwelapha: ukufakwa okulungile, lungisa ukucaciswa kwezingxenye futhi uthuthukise ubulukhuni bobuso besiqu se-valve.Intambo ye-trapezoidal ingcolile futhi isimo sokugcoba sibi;isiqu se-valve nezingxenye ezihlobene nazo zikhubazekile

Indlela yokwelapha: susa izinto ezebiwe, sebenzisa i-lubricant ku-valve yethusi yokushisa ephezulu ngesikhathi;lungisa izingxenye ezikhubazekile.
