Womabili amavalvu ebhola lesihlalo senyama kanye namavalve ebhola athambile ajwayeleke kakhulu, futhi kunomehluko omningi phakathi kwawo.

1.Isakhiwo

I-valve yebhola lesihlalo senyama isho uphawu phakathi kwensimbi nensimbi, kanti ibhola lokuvala nesihlalo kokubili kuyinsimbi.Isihlalo se-valve yebhola ehlezi kahle asiyona eyensimbi.

2.Izinto zokuvala

Ngaphansi kwezimo ezijwayelekile, i-valve yebhola lesihlalo senyama yenziwa ngokunembile yimpahla yesihlalo ukuze kuqinisekiswe ukunemba okuhambisanayo ne-valve core (ibhola), ngokuvamile insimbi engagqwali nethusi, kuyilapho uphawu oluthambile lusho ukuthi impahla yokuvala eshunyekwe esihlalweni izinto ezingezona ezensimbi , Ngenxa yokuthi izinto ezithambile zokufaka uphawu zinokunwebeka okuthile, izidingo zokunemba kokucubungula zizoba ngaphansi kunalezo zokuvalwa kwensimbi.

3.Ukusebenzisa

Ngokwemibandela yokusetshenziswa, ngokuvamile izimpawu ezithambile zingafinyelela emazingeni aphezulu, kuyilapho izimpawu zensimbi zingaba phezulu noma eziphansi ngokuvumelana nezidingo;izimpawu eziqinile ngokuvamile zingakhiqizwa ngomfutho ophezulu, kodwa izimvu zamanzi ezithambile azikwazi;izimpawu ezithambile zidinga ukuvikelwa komlilo, ngoba Ngaphansi kwezinga lokushisa eliphezulu, impahla yophawu oluthambile izovuza, kodwa uphawu lwensimbi alunayo le nkinga;uphawu oluthambile alukwazi ukusetshenziswa kwezinye izikhathi ngenxa yenkinga yendawo egelezayo (njengemithombo yezindaba egqwalayo);ivalve yensimbi yophawu ngokuvamile ibiza kakhulu kunophawu oluthambile.

4.Amazinga Okukhiqiza

Ngokombono wesimiso, i-valve yebhola evalwe ngensimbi kanye ne-valve yebhola evalwe ngokuthambile iyafana, kodwa ngenxa yokuthi iyisigxivizo phakathi kwezinsimbi, Ngakho-ke i-valve yesihlalo sensimbi kufanele icabangele ubulukhuni, kanye nezimo zokusebenza. , iyiphi indlela yokusebenza, njll. Ukwelashwa kokuqina ngokuvamile kudingwa i-valve yebhola lesihlalo sensimbi, futhi ukugaya okuqhubekayo phakathi kwebhola nesihlalo se-valve kuyadingeka ukuze kuzuzwe ukuvala.Umjikelezo wokukhiqiza wama-valve esihlalo sensimbi yinde, futhi ukucubungula kuyinkimbinkimbi, futhi akulula ukwenza ama-valve esihlalo sensimbi kahle.

5.Ukukhethwa Kwezisetshenziswa
