Kuiswa kwebhora vharafu

Ball valvekuiswa:

1. Inoda kusimbiswa kuti pombi uye kushanda kwevharuvhu kwacheneswa.

2. the actuator of thebhora vharafukushanda zvinoenderana nehukuru hwechiratidzo chekuisa kutyaira stem kutenderera: kutenderera kumberi 1/4 (90 °), iyobhora vharafuyakavharwa.Thebhora vharafuinovhurwa kana reverse kutenderera kuri 1/4 kutendeuka (90°).

3.Apo museve unoratidza nzira ye actuator inofananidzwa nepipeline, valve inovhurwa;Vhuru yakavharwa kana museve uri perpendicular to line.

Ball valvekuchengetedza:

Kuve nehupenyu hurefu hwesevhisi uye nguva yekuchengeta-yemahara zvinoenderana nezvakati wandei zvinhu: zvakajairwa kushanda mamiriro, kuchengetedza inowirirana tembiricha / kudzvanywa reshiyo, uye inonzwisisika corrosion data.

Cherechedza: apo iyobhora vharafuyakavharwa, kumanikidzwa kwemvura kuchiripo mumuviri wevharuvhu

Usati washanda, bvisa mutsara wekumanikidza uye nzvimbo yevhavha panzvimbo yakashama

Bvisa simba remagetsi kana mhepo isati yagadzirisa

Bvisa iyo actuator kubva mutsigiro usati wagadzirisa

1. Packing lock

Kana kurongedza culvert kuri mudiki kudonha, inofanira kukiya stem nati.

Ongorora: Usakiya, kazhinji kukiya 1/4 mhete kune 1 mhete, kuvuza kunomira.

2. Dzorera chigaro uye zvisimbiso

A. Bvisa

Siya vharafu iri pahafu-yakavhurika nzvimbo yekuvhenekesa mukati nekunze kwevharuvhu kune zvinogona kuve nengozi zvinhu.

Closebhora vharafu, bvisa mabhaudhi uye nzungu kubva kune ese maflange uye bvisa vharafu zvachose kubva papombi.

Bvisa drive - actuator, kubatanidza bracket, anti-loose washer, stem nut, butterfly shrapnel, Gernan, pfeka disc, stem kurongedza munhevedzano.

Bvisa mabhaudhi ekubatanidza mabhaudhi uye nzungu, paradzanisa chivharo kubva mumuviri, uye bvisa chivharo gasket.

Iva nechokwadi chokuti bhora riri mu "off" nzvimbo kuti ribvise nyore kubva mumuviri uye kubvisa chigaro.

Sunda dzinde zvinyoro nyoro pasi nepaburi repakati pemuviri kusvika ranyatsobviswa, wobva wabvisa O-ring uye mhete yekurongedza.

Ongorora: Chenjerera kudzivirira kukwenya hunde pamusoro uye kurongedza chisimbiso chevharuvhu.

B. Unganidzazve

Chenesa uye ongorora zvikamu pasi pekuongororwa.Kutsiviwa kwechigaro uye bonnet gaskets uye zvisimbiso zvine spare parts kit zvinokurudzirwa zvakanyanya.

Unganidza mune reverse kurongeka kwe disassembly.

Muchinjikwa - kiya mabhaudhi eflange ane torque yakataurwa.

Simbisa nzungu ne torque yakatarwa.

Mushure mekuisa actuator, tenderedza hunde yevharuvhu kuti utyaire spool kuti utenderere inopindirana yekuisa chiratidzo kuti uvhure nekuvhara vharuvhu.

Kana zvichibvira, chisimbiso chekumanikidza bvunzo uye performance test valve zvinoenderana neyakajairwa mushure mekuiswa kwepombi.
