Ukuthengiswa okuhle kwe-ductile iron halar coating enekhwalithi ephezulu ye-double flange concentric butterfly valve

Ivalvu ye-Butterfly ye-flange ephindwe kabili: amavalvu we-butterfly ahlangeneko athatha indawo eqakathekileko ngebanga lokusebenza kwawo ngendlela ehlukileko. I-atikili le ihlose ukukhanyisela ukuqakatheka nobujamo bevalvu engakajayeleki, khulukhulu emkhakheni wokuhlanza amanzi. Phezu kwalokho, sizokucoca ngokuthi ukuthengiswa okunqophileko kwefemu kwamavalvu amakhulu we-flanged concentric butterfly kunikela njani iinzuzo ezingalinganiswako ngeendleko nekhwalithi. Eyaziwa ngomklamo wayo olula kodwana osebenzako, ivalvu le inediski ebekwe hlangana namaphethelo amabili we-flange. Ukuvala okuqinileko hlangana nediski nomzimba kuqinisekisa ukuvuza okuncani, okwenza bona kube kuhle ekusetjenzisweni okutlhoga ukuvalwa okupheleleko. Phezu kwalokho, ukuklanywa kwayo okuncani nobunzima obulula kwenza bona kube lula ukufakwa nokutlhogonyelwa.

Nakuziwa ekuhlanzeni amanzi, amavalvu we-butterfly ahlangeneko abonakala ayigugu embonini. Njengoba isidingo sokulawulwa kwamanzi ngendlela ephumelelako siragela phambili nokwanda, ivalvu le sele iyisisombululo esithembekileko. Isetjenziswa khulu ekuphakeleni amanzi, ekuhlanzeni indle, eendaweni zokususa itswayi neminye imikhakha. Ikhono layo lokulawula ngokunembileko ukugeleza kwamanzi ngesikhathi iqinisekisa ukwehla komfutho ophasi kwenza bona ibe yingcenye eqakathekileko eendaweni zokuhlwengisa amanzi.
