"Maitiro Ekusarudza Globe Valve Zvakanaka: Gwaro reMarudzi uye Mamiriro Ekushandisa"
1,Overview
Globe valve imhando inowanzoshandiswa yevharuvhu, inonyanya kushandiswa kucheka mvura mumapaipi. Sarudzo chaiyo yekuvhara-vharavhavha ndiyo kiyi yekuve nechokwadi chekushanda kwakajairwa kwepombi masisitimu. Iri gwara richakuzivisa iwe nzira yekusarudza nemazvo vharafu yekuvhara, kusanganisira iyo mhando uye mamiriro ekushandisa.
2,Mhando yevhavha yekuvhara
1. Yakarongedzerwa nemagadzirirwo evharuvhu:
a) Yakatwasuka kuburikidza neglobe valve: Iyo fluid chiteshi yakatwasuka, ine yakapusa chimiro uye yakaderera kuyerera kuramba, ichiita kuti ishandiswe zvakanyanya.
b) Angle globe valve: Iyo fluid chiteshi iri pa 90 degree angle, inotora nzvimbo diki uye inokodzera mamiriro ane nzvimbo shoma.
c) Yakananga yazvino globe valve: Iyo fluid chiteshi yakatwasuka uye ine yakakwirira kuyerera kuramba, ichiita kuti ive yakakodzera kune mamiriro ane yakaderera kuvhura uye kuvhara ma frequency.
2. Yakarongedzwa nevharuvhu zvinhu:
a) Carbon simbi yeglobe vharafu: yakakodzera kune zvakajairwa maindasitiri mashandisirwo ane midhiya senge mvura, oiri, chiutsi, nezvimwe.
b) Stainless simbi yeglobe vharafu: inokodzera nharaunda dzine hutsanana hwakanyanya zvinodiwa, senge zvinoora zvinwiwa, magasi, makemikari, nezvimwe.
c) Fluorine lined globe valve: inokodzera nharaunda dzine makemikari anoparadza, maasidhi akasimba, alkali akasimba, uye mamwe midhiya.
3. Inorongwa nenzira yekutyaira:
a) Manual shut-off valve: Chengetedza kuvhura kwevhavha nekuvhara nemaoko kutenderera tsinde yevhavha, iri nyore uye iri nyore kushanda, yakakodzera kune yakaderera kudzvinyirira uye madiki madhiyamita maapplication.
b) Electric globe valve: Kudzora otomatiki kunowanikwa nekutyaira tsinde yevharuvhu kuti itenderere kuburikidza nemota yemagetsi, yakakodzera pakati nepakati kudzvanywa, yakakura dhayamita maapplication.
c) Pneumatic globe valve: Inotungamirirwa nemhepo yemhepo kuti itenderedze tsinde yevharuvhu, inobudirira kudzora otomatiki, yakakodzera pakati nepakati kumanikidza, yakakura dhayamita mamiriro.
3,Mamiriro ekushandisa eglobe mavharuvhu
1. Mvura yekugovera sisitimu: inoshandiswa kucheka zvitubu zvemvura, kuwana hurongwa hwekutanga, kudzima, uye kugadzirisa.
2. Petrochemical industry: inoshandiswa kucheka midhiya yakasiyana-siyana, yakadai semafuta, gasi, mvura, nezvimwewo, kuve nechokwadi chekuchengetedzwa kwekugadzirwa.
3. Thermal power generation industry: inoshandiswa kucheka midhiya yakadai semvura inopisa uye steam, kuve nechokwadi chekushanda kwakachengeteka kwemabhoilers nemidziyo inopisa.
4. Chikafu uye chinwiwa indasitiri: yakashandiswa kugura midhiya senge chikafu uye zvinwiwa, kuve nechokwadi chehutsanana hwenzvimbo yekugadzira.
5. Indasitiri yemishonga: inoshandiswa kucheka mishonga yemishonga, mishonga, uye mamwe ma media kuti asangane nezvinodiwa zvekugadzira.
6. Indasitiri yekudzivirira kwezvakatipoteredza: inoshandiswa kucheka midhiya yakadai setsvina uye sludge, uye kuzadzisa kushanda kwakajairika kwenzvimbo dzekuchengetedza nharaunda.
4,Kuchengetedza pakusarudza mavharuvhu ekuvhara
1. Sarudza zvakakodzera valve zvinhu maererano nehupfumi hwepakati (zvakadai sekuora, tembiricha, kudzvanywa, nezvimwewo).
2. Sarudza yakakodzera valve modhi zvinoenderana nedhizaini yekumanikidza, tembiricha yekugadzira, uye dhayamita yepombi.
3. Funga nzira yekufambisa yevhavha uye sarudza mavharuvhu emagetsi, emagetsi, kana pneumatic anovhara zvichienderana nemamiriro ezvinhu uye zvinodiwa.
4. Funga nzvimbo yekuisa uye kutungamirirwa kwevhavha kuti ive nechokwadi chekushanda kwayo.
5. Sarudza mavharuvhu anogadzirwa nevagadziri vanoremekedzwa kuti vave nechokwadi chehutano uye mushure mekutengesa-basa revhavha.
Muchidimbu, kusarudzwa kwakarurama kwemavhavhavha ekuvhara kunoda kunyatsotariswa kwezvinhu zvepakati, magadzirirwo emagetsi epombi, uye mamiriro ekushandiswa. Ndinovimba gwaro iri rinobatsira kwauri.
