Gate valve insanbalbula na kulibangbang parehon walay papel da ya man-switch tan man-regulate na agos ed panguusar na pipeline. Siempre, wala ni so paraan ed panagpili na butterfly valve tan gate valve. Pian nabawasan so kaaralem na dalin ya akasakbong ed tubo ed suplay na danum, kaslakan et saray mas angkakabaleg a diametro na tubo et walaan na butterfly valves, ya anggapoy epekto to ed kaaralem na dalin, tan mansasagpot iran manpili na gate valves.
Antoy pandumaan na butterfly valve tan gate valve?
Base ed kimey tan usar na gate valve tan butterfly valve, say gate valve et walaan na melag ya flow resistance tan maong ya sealing performance. Lapud say direksion na agos na gate valve plate tan say medium et walad vertical ya anggulo, no say gate valve et ag-aka-switch ed pasen to ed valve plate, say pan-scour ed medium ed valve plate et mamayegyeg ed valve plate. , Mainomay ya naderal so seal na gate valve. Say butterfly valve, ya tatawagen met ya flap valve, et sakey a klase na regulating valve ya simpli so istruktura to. Say butterfly valve ya nayarin usaren parad on-off control na low-pressure pipeline medium et mankabaliksan ya say mansara ya membro (disc o butterfly plate) et sakey a disc, ya onliliber ed valve shaft pian nalukasan tan nasaraan. Sakey a balbula ya nayarin usaren pian nakontrol so iyaagus na nanduruman klase na pluido a singa say dagem, danum, singaw, nanduruman makaderal a media, pitek, larak, likidon metal tan radioactive media. Saya so manunan manggagawa na betang na panagputot tan panag-throttle ed tubo. Say parte na panlukas tan pansara na butterfly valve et singa disc ya butterfly plate, ya manpapaliber ed mismon axis to ed laman na balbula pian nadampot so gagala na panlukas tan pansara odino pangi-adjust. Say butterfly plate et ipapaarap na valve stem. No man-90 la°, sarag ton sumpalen so sakey a panlukas tan pansara. Diad panguman ed deflection angle na disc, nakontrol so agos na medium.
Kondisyon tan medium na pantratrabaho: Say butterfly valve et matukoy parad pangiyakar na nanduruman makaderal tan agmakaderal iran pluido ed saray sistema na engineering a singa say producer, coal gas, natural gas, liquefied petroleum gas, city gas, ambetel tan ambetel ya dagem, chemical smelting tan power generation environmental protection, suplay na danum ed bilding tan drainage, tan arum nira. i-adjust tan putoten so agos na medium.
Say gate valve et walay lukas tan pansara ton member gate, say direksion na galaw na gate et perpendikular ed direksion na pluido, tan say gate valve et nayarin nalukasan tan nasara labat. Pian napaaligwas so panaggawa toor abilidad tan manggawa na deviation na sealing surface angle legan na panagproseso, sayan gate et tatawagen ya elastic gate.
No akasara so gate valve, say sealing surface et makapanmatalek labat ed medium pressure pian naseal, salanti, manmatalek labat ed medium pressure pian na-press so sealing surface na gate ed valve seat ed biek a dapag pian naseguro so sealing surface, ya self-sealing. Maslak ed saray gate valve et mapilit ya akasara, salanti, no say balbula et akasara, say gate et kaukolan ya ipuersa ed valve seat panamegley na puersa na paway pian naseguro so inka-seal na tapew.
Movement mode: Say gate na gate valve et onkukurang ed diretso a linya ed valve stem, ya tatawagen met yaOS&Y gate valve. Kaslakan et wala ray trapezoidal ya sinulid lift rod. Diad panamegley na nut ed tagey na balbula tan say guide groove ed laman na balbula, say rotary motion et manguman ed linear motion, salanti, say operating torque et manguman ed operating thrust. No nalukasan so balbula, no say lift height na gate et mipara ed 1:1 a danay na diametro na balbula, say fluid channel et sigpot ya anggapoy makaamper, balet sayan posisyon et ag nayarin bantayan legan na operasyon. Diad aktual ya pangusar, say toktok na valve stem et uusaren bilang tanda, salanti, say posisyon ya ag nayarin lukasan, bilang posisyon ton sigpot ya lukas. Pian nakonsidera so lock-up phenomenon lapud panguuman na temperatura, kaslakan ya lukasan itan ed tagey a posisyon, insan ompawil ed 1/2-1 turn, bilang posisyon na sigpot ya lukas a balbula. Kanian, say sigpot ya lukas a posisyon na balbula et nadetermina unong ed posisyon na gate (salanti, stroke). Wala ray gate valve stem nuts ya akapuesto ed gate, tan say pangipawil na handwheel so mamakiwas ed valve stem pian man-rotate, kanian ontagey so gate. Sayan klase na balbula et tatawagen ya Rotary stem gate valve oNRS gate valve.
