I-American Standard WeldingIvalve yePlagIngcaciso emfutshane:
I-valve yeplagi inesakhiwo esilula, ukutshintshwa ngokukhawuleza, ukuxhathisa ulwelo oluncinci, kunye nokusebenza ngokukhawuleza kwe-angular stroke.Kwimeko engxamisekileyo njengengozi, umbhobho unokudityaniswa ngokukhawuleza okanye uqhawulwe.Xa kuthelekiswa neevalvu zesango kunye neglowubhu, umsebenzi ubhetyebhetye ngakumbi kwaye iswitshi ikhawuleza.Ivalve yeplagi isebenzisa umzimba weplagi onemingxuma ephumela njengelungu lokuvula nokuvala, kunye nomzimba weplagi ujikeleza ngesiqu sevalve ukuqonda isenzo sokuvula nokuvala.
Uluhlu lwesicelo sevalvu edityanisiweyo yaseMelika esemgangathweni:
Ivalve ye-socket ye-American welding welding ferrule valve ifanelekile kwimibhobho yoxinzelelo oluqhelekileyo CLASS150~CLASS600LB, ubushushu obusebenzayo obuyi -29°C~180°C kwipetroleum, imichiza, amayeza, isichumisi, ishishini lamandla ombane, njl.
Iimpawu zesakhiwo sevalvu yeplagi edityanisiweyo yaseMelika:
1. Imveliso inesakhiwo esifanelekileyo, ukutywinwa okuthembekileyo, ukusebenza kakuhle kunye nokubonakala okuhle.
I-2, ukutywinwa kwe-valve ye-socket welding plug kufezwa ngokutywinwa kwendawo ejikeleze i-ferrule.Eyodwa 360° intsimbi yokukhusela umlomo wentsimbi.
3. Ivalve ayinamngxuma wokuqokelela i medium.
I-4, umlomo wensimbi unika umphumo wokuzihlambulula xa iqhude liguqulwa, lilungele i-viscous kunye nokulula ngokulula.
I-5, ukuhamba ngeendlela ezimbini, kulula ukuyisebenzisa kunye nokuyifaka.
6. Izinto eziphathekayo kunye nobukhulu be-flange bamacandelo anokuthi ahambelane ngokufanelekileyo ngokweemeko zangempela zokusebenza okanye iimfuno zomsebenzisi ukuhlangabezana neemfuno ezahlukeneyo zobunjineli.

Imiyalelo yofakelo lwevalvu yeplagi edityanisiweyo yaseMelika esemgangathweni:
1. Shiya indawo apho isiqu sevalve sijikeleza khona.
2. Ayinakusetyenziselwa ukungqusha.
3. Ivalve yebhola enomatshini wokusasaza kufuneka ifakwe ime nkqo.
