Umfanekiso oBonisiweyo weValvu yeSango leWellhead Slab ye-API 6A

Ivalvu yeSango leSlab yeWellhead ye-API 6A

Inkcazo emfutshane:

Iimbonakalo
1. Uyilo olupheleleyo lususa ngempumelelo ukuhla koxinzelelo kunye nemisinga ye-eddy kwaye lucothisa amasuntswana aqinileyo kulwelo
ukuhlanjwa kweevalvu;
2. Uyilo olulodwa lokutywina, ukuze i-torque yokutshintsha inciphe kakhulu;
3. Kwenziwa izitywino zesinyithi phakathi kwebhonethi kunye nomzimba wevalvu, ipleyiti yevalvu kunye neringi yesihlalo sevalvu;
4. I-welding ye-carbide eqinisiweyo nge-metal sealing spray (overlay), enokumelana nokuguguleka okuhle, ukumelana nokugqwala;
5. Indandatho yesihlalo iqiniswe yipleyiti esisigxina ukugcina uzinzo oluhle;
6. Isiqu sixhotyiswe ngendlela yokutywina eguqulweyo ukuze kube lula ukutshintsha iringi yokutywina isiqu ngoxinzelelo.

Iithegi zeMveliso

I-FC Slab Gate Valve

Ivalvu yeSango leSlab ye-FL

Iimbonakalo
1. Ingaphakathi lomzimba wevalvu alisebenzisi ngerabha njengento yokutywina;
2. Umzimba wevalvu wenziwa yinkqubo yokwenza i-die forging compression kube kanye;
3. Umzimba wevalvu, isihlalo sevalvu kunye nepleyiti yevalvu zonke ziitywina zesinyithi ukuya kwisinyithi,
4.Isebenza kakuhle ngokutywina kwaye iphila ixesha elide;
5. Isiqu sevalvu sinesitywina sangasemva, kwaye ukupakisha isitywina sevalvu kunokutshintshwa ngoxinzelelo;
6. I-torque yeswitshi yokusebenza kwevalvu ilula. Ingasetyenziswa ngumntu omnye phantsi koxinzelelo;
7. Iphini yokhuseleko yesiqu esingasetyenziswanga ikhusela isiqu ekuchetyweni.

Ivalvu yeSango leSlab yePFF

Iimbonakalo
1.Ngesiqu somsila esilinganayo ukulinganisela umthwalo wesiqu kunye nokunciphisa umsonto wentonga yevalvu kunye nomthwalo wokuthwala, kunciphisa i-torque yokusebenza;
2.Isakhiwo sentonga evulekileyo, esinokubonisa imeko yokuvulwa nokuvalwa kwevalvu;
3. Isiqu sevalvu sixhotyiswe ngendlela yokutywina eguqulweyo ukuze kube lula ukuyitshintsha ngee-stem seals zoxinzelelo;
4. Ivalvu yokufaka igrisi yokutywina inikwe kwicala elinye lebhonethi ukuze kube lula ukuyizalisa kwakhona
Ukuthambisa igrisi ukuphucula ukusebenza kokuthambisa kunye nokusebenza kokuthambisa kwepleyiti yevalvu kunye nesihlalo sevalvu. Iimpawu zokuthambisa
