I-Valve ye-Ball ye-Welded ngokupheleleyo ye-Forged Steel

Umzimba wena unye welded udityaniswe zii-hemispherical ezimbini, iinxalenye valve kunye umzimba spherical compact ngokugqibeleleyo kwiseti enye, ngaxeshanye inemandla aphezulu kunye nobunzima obuncinci, kunye nokukwazi ukumelana aphezulu uxinzelelo pipeline kunye noxinzelelo, uyilo umzimba valve spherical compact uphepha umzimba udityaniswe nge flange, ngaloo ndlela ukunciphisa valve ubume ubukhulu kunye nokupheliswa ukuvuza amajelo, kuphepha ubutyhefu kunye nokutshuka ulwelo ukusuka ukuvuza ngaphandle valve ibhola kwaye iba Ubomi bunokuba neminyaka engama-20.

Iimpawu zemveliso:

1. Umsebenzi womzimba wentsimbi egqwesileyo, qinisekisa ukuba akukho ngxunya, iinqheka njl iingxaki zomgangatho.

2. Ukumelana okulungileyo nokugqwala.

3. Ibhloko ephindwe kabini kunye nomsebenzi wokukhupha igazi, icala elingaphezulu nelisezantsi lesihlalo yenza ibhloko yemanzi, umzimba ugcina ukukhutshwa ngevalve yokukhupha.

4. Ukwakhiwa okukhuselekileyo komlilo.

5. Vula ngokukhawuleza nangokulula.

6. Isakhiwo esicocekileyo, ubunzima obulula, indlela encinci yokuphakama.

7. Inxalenye yokuvala ye-spherical inokufumana ngokuzenzekelayo kwindawo yomda, kwaye inokumelana umahluko oxinzelelo oluphezulu xa uvala.

8. Xa uvulekile ngokupheleleyo kwaye uvaliwe ngokupheleleyo, uvala ubuso bebhola nesihlalo esihlukileyo kwindawo ephakathi.

9. Ukuba nentshukumo ejikelezayo ye-90 degrees, ibhola inembongo ejikelezayo nge-axis, umgodi webhola ogcweleyo unciphisa ukumelana okuphakathi, wandise isijelo sokuhamba.

10. Iziphelo zevalve zinokongeza imibhobho.

11. Kunokusetyenziswa okungcwatyweyo, isithongo sinokongeza ngokweemfuno zeprojekthi, ibeke igarithi ehambelanayo, amanzi amdaka kunye nesixhobo sokuphefumla siquka ityhubhu elandiswe emhlabeni.

Isicelo:

Isebenza kwi: iikhemikhali, ipetroliyo, igesi yendalo, i-metallurgy, kunye namanye amashishini kunye neendaba eziqulathe i-hydrogen sulfide, izinto ezingcolileyo, imibhobho yegesi yomgangatho omde.
