Kuiswa kweBall Valve:
1. Inofanira kusimbiswa kuti mapaipi nemavhavha akacheneswa asati ashanda.
2. Kushanda kweactuator yevhavha inotyaira tsinde kuti itenderere maererano nehukuru hwechiratidzo chekupinza. Kana vharuvhu ichitenderera 1/4 nguva (900) munzira yekumberi, vharuvhu inovhara. Kana iyo reverse kutenderera iri 1/4 kutendeuka (900), vharuvhu inovhura.
3. Kana kutungamira kweactuator kunoratidza kuti museve unofanana nepombi, valve inovhura; apo museve uri perpendicular kune pipeline, valve inovhara.
Ball Valve Maintenance:
Hupenyu hurefu hwesevhisi uye nguva yekusagadzirisa-yemahara inotsamira pane zvakati wandei zvinhu: kuchengetedza inowirirana tembiricha/kudzvanywa reshiyo pasi pemamiriro ekushanda akajairwa, uye data ine corrosion data.
Ongorora: Kana vharuvhu yebhora yakavharwa, kudzvanywa kwemvura mumutumbi wevharuvhu kuchiripo.
Usati wagadzirisa, bvisa kudzvanywa kwemutsara uye chengeta vharafu munzvimbo yakashama
Usati wagadzirisa, bvisa simba kana gasi sosi
Kuparadzanisa actuator kubva kubhuraketi usati wagadzirisa
1. Kurongedza kukiya
Kana iyo culvert yekuzadza ichidonha zvishoma, stem nut inofanira kuvharwa.
Ongorora: Usakiya, kazhinji kukiya 1/4 mhete kune 1 mhete, kuvuza kunomira.
2. Kutsiviwa Kwezvigaro uye Zvisimbiso
A. Disassembly
Siya vharafu iri pahafu-yakavhurika nzvimbo uye bvisa zvinhu zvine njodzi zvinogona kunge zviripo mukati nekunze kwevharuvhu.
Vhara vharuvhu yebhora, bvisa mabhaudhi uye nzungu dzeflange pamativi ese, uye bvisa vharafu zvachose kubva papombi.
Dimbura mudziyo wekutyaira munhevedzano - actuator, kubatanidza bracket, anti-loosening washer, stem nut, butterfly spring, Gnan, kupfeka-resistant plate, stem packing.
Bvisa chivharo chemuviri chekubatanidza mabhaudhi nenzungu, paradzanisa chivharo kubva mumuviri, uye bvisa chivharo gasket.
Simbisa kuti bhora riri mu "off" position, izvo zvinoita kuti zvive nyore kuibvisa kubva mumuviri uye wozobvisa chigaro.
Dzinde rinosundirwa pasi neburi remuviri wevharuvhu kusvika rabviswa zvachose, uye ipapo O-ring uye mhete yekurongedza zvinobviswa.
Ongorora: Ndokumbira ushande nekuchenjerera kuti usakwenya hunde pamusoro uye kurongedza chisimbiso chevhavha.
B. Reassembly
Chenesa uye ongorora zvikamu zvakaongororwa. Kutsiviwa kwechigaro uye kuvhara gaskets uye zvisimbiso zvine spare parts package zvinokurudzirwa zvakasimba.
Unganidza mune reverse kurongeka kwe disassembly uye kuungana.
Cross-lock flange mabhaudhi ane torque yakatarwa.
Kiya nzungu ne torque yakatarwa.
Mushure mekuisa actuator, spool yevharuvhu inofambiswa kutenderedza inopindirana chiratidzo chekuisa nekutenderedza hunde kuita kuti vharafu rivhure uye rivhare.
Kana zvichibvira, edza kuvharisa chisimbiso uye kushanda kwevhavha maererano nechiyero mushure mekuiswa kwepombi.
