Iimpawu zevalvu yebhola ziyaziswa

Njengoko isetyenziswa kakhulu kwiivalvu, iivalvu zebhola zineempawu ezibalulekileyo ezenza ukuba zisetyenziswe kakhulu kumashishini nakwizicelo ezahlukeneyo. Ezi zilandelayo zezona mpawu ziphambili zevalvu yebhola:

1. Ukumelana nolwelo oluphantsi:

- Umjelo webhola wevalvu yebhola ungqukuva, kwaye ububanzi bomjelo bulingana nobubanzi bangaphakathi bombhobho xa uvuliwe ngokupheleleyo, ngoko ke ukumelana kolwelo oludlulayo kuncinci kakhulu.

2. Ukuvula nokuvala ngokukhawuleza nangokulula:

- Ukuvulwa nokuvalwa kwevalvu yebhola kungenziwa kuphela ngokujikeleza ama-90 degrees, kwaye umsebenzi ukhawuleza kwaye ulula, kulula ukuwunqumla.

3. Ukusebenza kakuhle kokutywina:

- Ivalvu yebhola ngexesha lokuvulwa nokuvalwa, ibhola kunye nesihlalo zenza unxibelelwano olusondeleyo, kunye nokusebenza kakuhle kokutywina, kunokuthintela ukuvuza kwemidiya.

4. Isakhiwo esilula, ubungakanani obuncinci, ubunzima obulula:

Ulwakhiwo lwevalvu yebhola lulula kwaye luneendawo ezimbalwa, ngoko ke luncinci ngobukhulu, lulula ngobunzima kwaye kulula ukuyifaka nokuyilungisa.

5. Uluhlu olubanzi lwesicelo:

Ivalvu yebhola inoluhlu olubanzi lweedayamitha, ukusuka kwiimilimitha ezimbalwa ukuya kwiimitha ezimbalwa, ifanelekile kwiindidi ezahlukeneyo zemidiya kunye neemeko zokusebenza, kubandakanya ubushushu obuphezulu, uxinzelelo oluphezulu, imidiya ebolileyo, njl.

6. Ukuhamba okulungisekayo:

- Ezinye iivalvu zebhola (ezifana neevalvu zebhola ezimile okwe-V) zinomsebenzi wokulawula isantya sokuhamba, kwaye isantya sokuhamba kwesixhobo singalungiswa ngokutshintsha indawo yebhola.

7. Ingangeni thuli kwaye ayitshintshi:

- Kwizicelo ezithile, iivalvu zebhola zingasetyenziselwa ukusasaza izinto kunye nokuthintela amasuntswana esinyithi ukuba angangeni kwigumbi lepompo, ngelixa kususwa umngcipheko womlilo obangelwa ngumbane ongashukumiyo.

8. Iindlela zonxibelelwano ezahlukeneyo:

- Ivalvu yebhola ingakhethwa ngokweemfuno zoqhagamshelo lweflange, uqhagamshelo lwentambo, uqhagamshelo lwe-welding kunye nezinye iindlela zoqhagamshelo ukuze zilungelelaniswe neenkqubo ezahlukeneyo zemibhobho.

9. Iindlela ezahlukeneyo zokuqhuba:

- Ivalvu yebhola inokukhethwa ngokweemfuno zokwenyani zendlela zokuqhuba ngesandla, zombane, zomoya kunye nezinye iindlela zokuqhuba ukuze kufezekiswe ulawulo olukude kunye nokusebenza ngokuzenzekelayo.

Ngamafutshane, ivalvu yebhola enokumelana nolwelo oluphantsi, ukuvulwa nokuvalwa okukhawulezayo nokulula, ukusebenza kakuhle kokutywina, ulwakhiwo olulula noluncinci, uluhlu olubanzi lwezicelo kunye nezinye iimpawu ezibalulekileyo, kwi-petroleum, iikhemikhali, ukutya, amayeza, unyango lwelindle kunye neminye imboni ziye zasetyenziswa kakhulu.
