Waalka waxaa loo isticmaalaa in lagu furo oo la xiro dhuumaha, xakamaynta jihada socodka, hagaajinta iyo xakamaynta xuduudaha dhexdhexaadiyaha gudbinta (heerarka, cadaadiska iyo socodka) qalabka dhuumaha.Marka loo eego shaqadiisa, waxa loo qaybin karaa valve shutoff, valve check, valve regulating, iwm.

Walafku waa qaybta kontoroolka ee nidaamka gudbinta dareeraha, kaas oo leh hawlaha jarista, nidaaminta, leexinta, ka-hortagga ka-hortagga, xasilinta cadaadiska, leexinta ama gargaarka qulqulka, iwm. kuwa loo isticmaalo nidaamyada iswada ee ugu adag.

Valves waxaa loo isticmaali karaa in lagu xakameeyo socodka hawada, biyaha, uumiga, warbaahinta daxalaysa, dhoobada, saliidda, birta dareeraha ah iyo warbaahinta shucaaca iyo noocyada kale ee dareeraha.Valves marka loo eego maaddada waxa kale oo loo qaybiyaa birta birta ah ee shubka ah, birta birta ah ee la tuuray, birta birta ah (201, 304, 316, iwm). , alwaaxyada gaarka ah ee aan caadiga ahayn.

Valve wuxuu ku jiraa nidaamka dareeraha, loo isticmaalo in lagu xakameeyo jihada dareeraha, cadaadiska, socodka qalabka, waa in la sameeyo tuubada iyo qalabka dhexdhexaadka ah (dareere, gaas, budada) ama joogsada oo xakameeyo socodka qalabka .

Waalka waa qaybta kontoroolka ee habka gudbinta dareeraha dhuumaha, loo isticmaalo in lagu beddelo qaybta marinka iyo jihada socodka dhexdhexaadka ah, iyada oo la leexinayo, gooyn, ceejinta, hubinta, leexinta ama hawlaha gargaarka cadaadiska qulqulka.Valve loo isticmaalo xakamaynta dareeraha, laga bilaabo kan ugu fudud globe valve ilaa nidaamka xakamaynta tooska ah ee aad u adag ee loo isticmaalo noocyada kala duwan ee valves, kala duwanaanshihiisa iyo tilmaamihiisa, cabbirka magaca magaca ee waalka laga bilaabo qalabka aadka u yar ilaa xajmiga dhuumaha warshadaha. valve ilaa 10m.Waxaa loo isticmaali karaa in lagu xakameeyo biyaha, uumiga, saliidda, gaaska, dhoobada, noocyo kala duwan oo warbaahin ah, biraha dareeraha ah iyo dareeraha shucaaca iyo noocyada kale ee socodka dareeraha, cadaadiska shaqada ee waalka wuxuu noqon karaa 0.0013MPa ilaa 1000MPa oo ah ultra-sare cadaadiska, heerkulka shaqada wuxuu noqon karaa C-270 ℃ heerkulka ultra-hoose ilaa 1430 ℃ heerkul sare.

Waalka waxaa lagu xakameyn karaa noocyo kala duwan oo ah hababka gudbinta, sida buug-gacmeedka, koronto, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic, electro-hydraulic, electro-hydraulic, gaas-hydraulic, spur gear, bevel gear drive;Cadaadiska, heerkulka ama qaab kale oo hoos yimaada ficilka calaamadaha dareemayaasha, ficil, marka loo eego shuruudaha boos celinta ama kuma xirna calaamadaha dareemayaasha si fudud u furan ama xiran, ku tiirsan darawalka ama habka otomaatiga ah ayaa ka dhigaya furitaanka iyo xiritaanka valve kor u qaadis, simbiriirixan, meel ama dhaqdhaqaaq wareeg ah, si loo beddelo cabbirka dekedda si loo xaqiijiyo shaqada xakamaynta.
