1.0 tung tung ikum OS&Y Gate Valves ku NRS Gate Valves

Pol kare juneno i gate valves utiye rising stem gate valve man non-rising stem gate valve, ma gi rom rom, niwacu:

(1) Gate valves seal through contact kind valve seat ku valve disc.

(2) Kit gate valves ario zoo gitiye ku disc calu piny ma yabo man ma cego, man wotho pa disc utiye ma rwate ku yo ma pii ucidho i iye.

(3) Gate valves copo bedu kende kende ma oyabe nyo cego, man ecopu bedu ngo pi yub nyo throttling.

Dong, tung tung ango ma utiye ikind gi?TWSbi gonyo tung tung mi rising stem gate valves ku non-rising stem gate valves.

OS&Y Gate Valve

Roting handwheel miyo threaded valve stem malo kata piny, ma miyo gate mondo oyab kata cego valve.

NRS Gate Valve

Non-Rising Stem (NRS) gate valve, ma julwonge bende ni rotating stem gate valve nyo non-rising stem wedge gate valve, utiye ku stem nut ma juketho iwi disc. Ka iloko handwheel loko valve stem, ma tingo nyo dwoko piny disc. Pol kare, thwol ma calu trapezoid juyike i thenge ma piny pa lum. Thread eni, ma tiyo ku guide channel iwi disc, loko rotational motion ni linear motion, man eloko torque mi tic ni thrust force.

Poro pa NRS ku OS&Y Gate Valves i tic:

1. Nen pa yen: stem pa OS&Y gate valve nen woko man nen, ento pa NRS gate valve utiye i iye man nen ungo.
2. Yore mi tic: OS&Y gate valve tiyo ku threaded engagement ikind stem ku handwheel, ma tingo nyo dwoko piny stem ku disc assembly. I NRS valve, handwheel loko stem, ma lokore idisc, man thwol pare mako ku nut iwi disc mi tingo malo nyo piny.
3. Kabedo: The drive threads pa NRS gate valve utiye iiye. I kare mi tic, stem ne lokore kende, ma weko neno pa valve ubedo tek. Ku lapor, thwol pa OS&Y gate valve utiye woko, ma weko kabedo pa disc nen maleng man maleng.
4. Kabedo ma mitere: NRS gate valves utiye ku kit ma yot ku bor ma rom, ma mitu kabedo manok mi kethu. OS&Y gate valves utiye ku bor madit ka oyabere, ma mitu kabedo madwong.
5. Gwoko man tic: Theng ma woko pa OS&Y gate valve konyo gwoko man lwoko yot. Threads ma iye pa NRS gate valve tek ni tiyo kudu man gibedo yot ni rwinyo piny, ma weko valve bedo yot ni nyothre. Kumeno, OS&Y gate valves utiye ku tic madwong.

Kit ma juyubu kudu OS&Y gate valve man NRS gate valves jupoko gi ni:

1. OS&Y Gate Valve:Valve stem nut utiye iwi valve cover nyo bracket. Ka ibe yabo nyo cego valve disc, tingo nyo dwoko piny pa valve stem jutimo ku loko valve stem nut. Kit gedo eni ber pi lwoko valve stem man eketho kabedo mi yabo man mi cego nen maleng, eno re m'uketho jutiyo kudu lee.
2. NRS Gate Valve:Valve stem nut utiye i iye pa valve man utiye i cing piny ma iye. Ka ibe yabo nyo i cego valve disc, valve stem ju loko pi timo eni. Ber pa gedo eni utiye nia bor pa gate valve ubedo marom, ci emito kabedo manok mi ketho, ma weko etiye ber pi valve madongo nyo valve ma kabedo manok mi ketho. Kit valve eni umaku obed ku lanyuth ma nyutho kama valve utiye iye. Peko pa kit gedo eni utiye nia valve stem threads copo bedu ngo ku moo man gibedo iwi piny ma iye, ma weko gibedo yot ni nyayu ret.

Ajiki

I lembe mayot, bero pa rising stem gate valves utiye i bedo yot migi mi nenu, bedo yot mi gwoko, man tic maber, ma weko gibedo piny ma pol kare tiyu kudu. Icing ling acel, bero pa non-rising stem gate valves utiye kit ma gi nen kudu man gi gwoko kabedo, ento eni bino ku bey pa bedo yot man yot pa gwoko, pieno pol kare jutiyo kudu i kare ma kabedo nok. Ka ibe yero, umitu ing'ei kit gate valve ma ibi tiyo kudu malubiri ku kabedu mi ketho, kite mi gwoko, man kabedu mi tic. Mi medo iwi rwom pare ma malu i thenge mi gate valves, TWS de unyutho diru pare ma tek i kabedo madwong calubutterfly valves, nen valves, manvalves mi rwom. Wacopu konyi ni yero kit piny maber pi tic peri man wa jolo kare mi yiko piny peri nimakere ku yeny peri. Wabi miyo gony matuc ikum tung tung mi rising stem ku non-rising stem gate valves i dul mwa mukende. Bed moth.
