Flange Gerbang klep mangrupakeun klep Gerbang kalawan sambungan flange, metoda sambungan ieu paling umum. Klep gerbang flange stabil sareng dipercaya nalika dianggo dina saluran pipa, janten klep gerbang flange sering dianggo dina pipa tekanan tinggi.
Nalika klep gerbang flange ditutup, permukaan sealing ngan ukur tiasa ngandelkeun tekanan sedeng pikeun ngégél, nyaéta, ngandelkeun tekanan sedeng pikeun pencét permukaan sealing gerbang ka korsi klep di sisi séjén pikeun mastikeun sealing tina. permukaan sealing, nu timer sealing. Kalolobaan valves Gerbang ngagunakeun sealing kapaksa, nyaeta, nalika klep ditutup, gerbang kudu dipaksa ngalawan korsi ku kakuatan éksternal pikeun mastikeun sealing tina beungeut sealing.
Gerbang klep Gerbang ngalir sacara linier sareng batang klep, anu disebut klep gerbang batang angkat (disebut ogé klep gerbang batang angkat). Biasana aya benang trapezoidal dina rod angkat. Ngaliwatan nut dina luhureun klep jeung alur pituduh dina awak klep, gerak Rotary dirobah jadi gerak linier, nyaeta, torsi operasi robah jadi dorong operasi.
Nalika klep dibuka, nalika jangkungna ngangkat gerbang sarua jeung 1: 1 kali diaméter klep, petikan cairan sagemblengna unblocked, tapi posisi ieu teu bisa diawaskeun salila operasi. Dina pamakéan sabenerna, apex tina batang klep dipaké salaku tanda, nyaeta, posisi dimana eta teu bisa dibuka, salaku posisi pinuh kabuka na. Dina raraga tumut kana akun fenomena ngonci alatan parobahan suhu, klep biasana dibuka ka posisi Apex lajeng rewinded ku 1/2 ka 1 péngkolan salaku posisi klep pinuh kabuka. Ku alatan éta, posisi kabuka pinuh tina klep ditangtukeun ku posisi gerbang (ie stroke>.
Dina sababaraha valves Gerbang, nut bobot disetel dina gerbang, sarta rotasi handwheel drive rotasi batang klep pikeun ngangkat gerbang. Jenis klep ieu disebut klep gerbang bobot puteran atanapi klep gerbang bobot poék.
Pamasangan flange gate valve:
1. Pariksa jero rohangan klep jeung beungeut sealing saméméh instalasi, sarta euweuh kokotor atawa keusik partikel anu diwenangkeun taat;
2. The bolts unggal bagian sambungan bakal merata tightened;
3. Pariksa bagian packing bisa dipencet pageuh, teu ngan pikeun mastikeun tightness of packing, tapi ogé pikeun mastikeun lawang fléksibel tina gerbang;
4. Sateuacan masang klep, pamaké kudu pariksa model klep, ukuran sambungan na nengetan arah aliran tina sedeng pikeun mastikeun konsistensi jeung sarat klep;
5. Nalika masang klep, pamaké kudu cagar spasi diperlukeun pikeun klep drive;
6. The wiring sahiji alat drive kudu dilaksanakeun nurutkeun diagram wiring;
7. The klep Gerbang kudu dijaga rutin, sarta henteu tabrakan atawa squeeze diwenangkeun ulah mangaruhan segel.
Bahan klep Newsway
Awak klep NSW sareng bahan motong tiasa ditawarkeun dina jinis Forged sareng jinis Casting. Gigireun bahan stainless steel sarta karbon, urang ogé rancang valves dina bahan husus kayaning titanium, alloy nikel, HASTELLOY® *, INCOLOY®, MONEL®, Alloy 20, super-duplex, alloy tahan korosi jeung bahan kelas uréa.
