Isimiso Esisebenzayo Nezinzuzo ze-Taike Valve Plug Valve

I-valve yokuxhuma, i-valve esebenzisa umzimba wepulaki onembobo ephumela njengelungu elivulayo nelivalayo. Umzimba wepulaki uzungezisa ngentonga yevalvu ukuze kuzuzwe isenzo sokuvula nokuvala, I-valve yepulaki encane ngaphandle kokupakisha yaziwa nangokuthi “iqhude”. Umzimba wepulaki we-valve yepulaki ngokuvamile uwumzimba oyi-conical (owaziwa nangokuthi isilinda), osebenzisana nembobo ewugqinsi yomzimba we-valve ukwenza ipheya evalayo. I-valve yokuxhuma iwuhlobo lokuqala lwe-valve eyasetshenziswa, enesakhiwo esilula, ukuvuleka nokuvala ngokushesha, nokumelana noketshezi oluphansi.Ama-valve epulaki avamile ancike ekuxhumaneni okuqondile phakathi kwepulaki yensimbi eqediwe kanye nomzimba we-valve ukuze kuvaleke, okuholela ekusebenzeni kabi kokuvala. , amandla okuvula nokuvala okuphezulu, nokuguga kalula. Ngokuvamile zisetshenziswa kuphela ezinhlelweni eziphansi (hhayi ngaphezulu kuka-1 MPa) kanye nobubanzi obuncane (ngaphansi kuka-100 mm). Ukuze kwandiswe uhla lokusebenzisa ama-valve epulaki, kwakhiwe izakhiwo eziningi ezintsha. I-valve yepulaki egcotshwe ngamafutha iwuhlobo olubaluleke kakhulu. Amafutha okuthambisa akhethekile ajovwa kusukela phezulu emzimbeni wepulaki phakathi kwembobo ecijile yomzimba we-valve kanye nomzimba wepulaki ukuze kwakheke ifilimu kawoyela ukuze kuncishiswe itorque yokuvula nokuvala, ukuthuthukisa ukusebenza kokuvala nempilo yesevisi. Ingcindezi yokusebenza kwayo ingafinyelela ku-64 MPa, izinga lokushisa eliphakeme lokusebenza lingafinyelela ku-325 ℃, futhi ububanzi obukhulu bungafinyelela ku-600 mm. Kunezindlela ezahlukahlukene zokudlula ama-valve amapulaki. I-straight through type ejwayelekile isetshenziswa ikakhulukazi ukunqamula uketshezi. Ama-valve amapulaki ezindlela ezintathu nanezindlela ezine afanele amapulaki ahlehlisa uketshezi. Ilungu lokuvula nokuvala le-valve yepulaki iyisilinda ene-perforated ejikelezayo mayelana ne-axis perpendicular esiteshini, ngaleyo ndlela ifinyelele injongo yokuvula nokuvala isiteshi. Ama-valve okuxhuma asetshenziswa kakhulu ukuvula nokuvala amapayipi kanye nemidiya yemishini.

Izinzuzo eziyinhloko zama-plug valves zimi kanje:

1. Ifanele ukusebenza njalo, ukuvulwa nokuvala okusheshayo nokulula.

2. Ukumelana noketshezi oluphansi.

3. Isakhiwo esilula, usayizi omncane uma kuqhathaniswa, isisindo esilula, nokugcinwa kalula.

4. Ukusebenza kahle kokubekwa uphawu.

5. Isiqondiso sokugeleza se-medium singaba ngokunganaki, kungakhathaliseki isiqondiso sokufaka.

6. Akukho ukudlidliza, umsindo ophansi.

7. Ama-valve epulaki angahlukaniswa abe yizinhlobo ezine ngokuya ngesakhiwo sawo: ama-valve epulaki aqinile, ama-self sealing plug valve, amapulaki okupakisha, nama-valve epulaki yomjovo kawoyela. Ngokohlobo lwesiteshi, singahlukaniswa ngezinhlobo ezintathu: iqonde ngohlobo, uhlobo lwezindlela ezintathu, kanye nohlobo lwezindlela ezine.
