Ivalve yokujonga i-Swing yivalve edla ngokuvumela ulwelo (ulwelo okanye igesi) ukuba luqukuqele kuyo kwicala elinye kwaye ithintele ukuhamba kwelinye icala.Zisetyenziswa ngokubanzi kwi-petroleum, iikhemikhali, ukutya, amayeza, i-textile, amandla, iilwandle, i-metallurgy, iinkqubo zamandla, njl.
I-disc yeevalve zokujonga i-swing inobume obungqukuva;yenza iintshukumo ezijikelezayo ecaleni komgca osembindini we-shaft osebenza luxinzelelo lolwelo, ulwelo luqukuqela ukusuka kwicala lokungena ukuya kwicala lokuphuma.Xa uxinzelelo lokungena luphantsi kunoxinzelelo lwe-outlet, i-disc yayo inokuvala ngokuzenzekelayo ngenxa yezinto ezifana nokwahlukana koxinzelelo lwe-fluid kunye ne-deadweight ukukhusela umbane ukuba ungabuyeli umva;
Iimpawu eziphambili zokwakha ze-JLPV Swing check valve zilandelayo:
1.Uyilo lwesakhiwo se-trim eyakhelwe-ngaphakathi
Ivalve ye-JLPV yokukhangela ithatha isakhiwo esakhelwe ngaphakathi.I-disc ye-valve kunye nengalo ye-hinge zombini ngaphakathi kwegumbi layo langaphakathi, ngoko ke ayinayo impembelelo ekuhambeni kwayo kunye nokunciphisa iindawo zayo zokuvuza;
2.Isitulo somzimba esidityanisiweyo okanye esonganyelweyo okanye isihlalo esidityanisiweyo kwaye sogqunywe ngeentlobo zemathiriyeli.
I-Welded overlay ihambelana ngokungqongqo nemigaqo ye-WPS evunyiweyo.Emva kwe-welding kunye nako konke ukunyangwa kobushushu obufunekayo, ubuso be-ring ring bulungiswa ngoomatshini, bucocwe kakuhle kwaye buhlolwe ngaphambi kokuba bahambe baye kwindibano.
3.Ubukhulu obukhulu bubonelelwa ngendandatho yokuphakamisa ukunyusa, ngaloo ndlela kulula ukufakela;Iivalvu zokujonga i-Swing zinokufakwa kwicala elithe tye okanye elithe nkqo.
Uluhlu lwe-JLPV Swing yoyilo lwevalvu yokujonga luhamba ngolu hlobo lulandelayo:
1.Ubukhulu: 2 "ukuya ku-48" DN50 ukuya kwi-DN1200
2.Uxinzelelo: Udidi lwe-150lb ukuya kwi-2500lb PN10-PN420
I-3.Izinto eziphathekayo: Insimbi yeCarbon kunye nensimbi engenasici kunye nezinye izinto ezikhethekileyo.
I-NACE MR 0175 i-anti-sulfur kunye ne-anti-corrosion metal materials
4.Uqhagamshelo luphela: ASME B 16.5 kubuso obuphakanyisiweyo (RF), ubuso beFlat (FF) kunye noLuhlu lweRingi ngokudibeneyo (RTJ)
ASME B 16.25 kwiziphelo ze-butt welding.
5.Imilinganiselo yobuso ngobuso: ihambelana ne-ASME B 16.10.
6.Ubushushu: -29℃ ukuya ku-425 ℃
