1.0 Say pandumaan na OS&Y Gate Valves tan NRS Gate Valves

Say kaslakan ya nanengneng ed saray gate valve et say rising stem gate valve tan say non-rising stem gate valve, ya walaan na pigaran pamparehoan, salanti:

(1) Saray gate valve et manseal ed baetan na valve seat tan say valve disc.

(2) Parehon klase na gate valve so walaan na disc bilang panlukas tan pansara ya elemento, tan say galaw na disc et perpendikular ed direksion na pluido.

(3) Saray gate valve et nayarin sigpot labat ya lukasan odino sigpot ya isara, tan ag nayarin usaren parad regulasyon odino panag-throttle.

Kanian, anto ray pandumaan da?TWSmangipaliwawa ed pandumaan na saray ontatagey a stem gate valves tan saray ag-ontatagey a stem gate valves.

OS&Y Gate Valve

Say pangipawil ed handwheel et mamaatagey o mamaabeba ed threaded valve stem, ya onkiwas ed gate pian nalukasan o nasara so balbula.

NRS Gate Valve

Say Non-Rising Stem (NRS) gate valve, ya tatawagen met ya rotating stem gate valve odino non-rising stem wedge gate valve, et walay stem nut ya akapeket ed disc. No ibalikas so handwheel, say valve stem et mamaatagey odino mamaabeba ed disc. Kaslakan, say trapezoidal ya sinulid et gagawaen ed abeban sampot na sanga. Sayan thread, ya mikonektaan ed sakey a giya ed disc, et manguuman ed rotational motion ya magmaliw ya linear motion, kanian say operating torque et magmaliw ya thrust force.

Say Pankompara na NRS tan OS&Y Gate Valves ed Aplikasyon:

1. Say Stem Visibility: Say stem na OS&Y gate valve et akapaway tan nanengneng, bangbalet say NRS gate valve et akasara ed loob na valve body tan ag nanengneng.
2. Mekanismo na Panangusar: Say OS&Y gate valve et mankikimey panamegley na threaded engagement ed baetan na stem tan say handwheel, ya mamaatagey o mamaabeba ed stem tan disc assembly. Diad NRS valve, say handwheel so mamapalikdo ed stem, ya onliliber eddisc, tan saray sinulid to et onsasabi ed sakey a nut ed disc pian ontagey odino onleksab itan.
3. Indikasyon na Posisyon: Saray drive thread na NRS gate valve et walad loob. Legan na operasyon, say sanga et onliliber labat, kanian imposiblin nanengneng so kipapasen na balbula. Diad kasunian, saray thread na OS&Y gate valve et walad paway, kanian malinew tan direktan nanengneng so posisyon na disc.
4. Kaukolan ya espasyo: Saray NRS gate valves et mas masimpit so desinyo da ya agmanguman so katagey da, ya kaukolan ya mas daiset so espasyo parad pangipaalagey. Saray OS&Y gate valves et walaan na mas baleg ya kaatagey no sigpot ya lukas, kanian kaukolan so mas dakel ya espasyo.
5. Panmintina tan Pangusar: Say paway na stem na OS&Y gate valve et mamagaan ed panmintina tan panag-lubricate. Saray loob na sinulid na NRS gate valve et mas mairap ya serbisyoan tan mas mainomay ya naapektoan na direktan media erosion, kanian mas mainomay ya naderal so balbula. Kanian, say OS&Y gate valves et walaan na mas malaknab ya aplikasyon.

Say desinyo na istruktura na OS&Y gate valve tan NRS gate valves et aka-kategorya ed onggendan:

1. OS&Y Gate Valve:Say nut na stem na balbula et walad tapew na balbula o bracket. No lukasan o isara so valve disc, say pangitagey o pangiyabeba ed valve stem et nagawaan diad pangipawil ed valve stem nut. Sayan istruktura et makagunggona ed panag-lubricate na valve stem tan malinew ya nanengneng so posisyon na panlukas tan pansara, kanian malaknab ya uusaren itan.
2. NRS Gate Valve:Say nut na stem na balbula et walad loob na laman na balbula tan direktan akakontak ed medium. No lulukasan o isara so valve disc, say valve stem et ipawil pian nagawaan iya. Say bentaha na sayan istruktura et say inkalapagan ya katagey na gate valve et ag manguman, kanian mas daiset so kaukolan ya espasyo parad pangipaalagey, kanian matukoy itan parad saray balbula ya angkakabaleg so diametro da odino saray balbula ya limitado so espasyo parad pangipaalagey. Sayan klase na balbula et nepeg ya walay indikasyon ya lukas/sara pian nanengneng so posisyon na balbula. Say disbentaha na sayan istruktura et ag nayarin na-lubricate iray valve stem threads tan direktan napapaarap ed medium, kanian mainomay iran naderal.

Konklusyon

Diad simplin panangibaga, saray bentaha na rising stem gate valves et say mainomay dan obserbaan, kombenientin manmintina, tan napanmatalkan ya operasyon, kanian mas kaslakan iratan ed regular ya aplikasyon. Diad biek a dapag, saray bentaha na non-rising stem gate valves et say kompakton istruktura tan desinyo ra ya makatipid na espasyo, balet saya so manresulta ed gastos na intuitive tan mainomay ya manmintina, kanian mabetbet iran uusaren ed saray situasyon ya walay espisipikon limitasyon na espasyo. No manpipili, nepeg mon desidien no dinan a klase na gate valve so usaren base ed espisipikon pasen ya pangipuesto, kondisyon na panmintina, tan kaliberliber na panag-operate. Nilikud ed sankaunaan ya posisyon to ed lawak na gate valves, say TWS et angipatnag met na mabiskeg iran teknikal a abilidad ed dakel a lawak a singa saybalbula na kulibangbang, check valves, insanbalbula na panagbalanse. Sarag mi kan tulongan ya manpili na sankaabigan ya klase parad aplikasyon mo tan awaten mi so pankanawnawan i-adapta itan ed eksakton pankaukolan mo. Mangiter kami na mas detalyadon eksplinasyon ed pandumaan na rising stem tan non-rising stem gate valves diad ontumbok a seksion mi. Mansiansia kayo.
