Tic pa Valve Gasket man yore mi tic kudu

Valve gaskets juyike pi juku pii ma wok kud i pressure, corrosion, man thermal expansion/contraction ikind piny moko. Kadok nwango zo flangedribri's valves mitu gaskets, tic migi man beru migi lokore nimakere ku kit valve man kite ma juyubu kudu. I thenge eni,TWSbi gonyo kabedo mi ketho valve man yero jam tic mi gasket.

I. Tic ma pire tek pa gaskets utiye i flange joint pa valve connections.

Valve ma pol kare jutiyo kudu

1. Gate Valve
2. Globe Valve
3. Butterfly valve(mandha ne concentric man double eccentric flanged butterfly valve)
4. Nen valve

I kind valve eni, gasket tiyu ngo pi jwigo mol pa valve kende, ento juyike ikind flanges aryo (i kind flange pa valve gire ku flange pa pipe). Ka jukubo bolt, tego ma romo mi mako piny juyubu pi yubu seal ma ucungo, ma juku pii ma wok kud i iye. Tic pare utiye mi pongu kabedo ma nok ma rwinyo ngo ikind dul ario mi flange, mi neno ni 100% ucungo kama jucokiri i iye.

II.Tic ku Gasket i Valve "Valve Cover"

Valve madwong juyike ku valve bodies matung tung man umu pi gwoko piny ma iye yot (e.g., loko valve seats, disc valves, nyo wodhu lum), ma juyike karacelu. Gasket de mitere i dhu dhu eni pi bedo tek.

1. Ribu pa valve cover ku valve body pa gate valve man globe valve pol kare mitu tic ku gasket nyo O-ring.
2. Gasket ma ni i kabedu eni de tiyo calu static seal mi juku piny ma wok kud i valve kud i polo.

III. Gasket ma pire tek pi kit valve moko

Valve moko ketho gasket calu thenge mi core sealing assembly migi, ma juyike ni bedu ikind valve structure.

1. Butterfly valve-valve seat gasket

• Kabedo pa butterfly valve ubedo ring gasket, ma juketho i kor ot pa valve nyo juketho i butterfly disc.
• Kinde ma winyodisccego, ediyo valve seat gasket ni yubu dynamic seal (calu butterflydisclokore).
• Piny ma jutiyo kudu ubedo rubber (e.g., EPDM, NBR, Viton) nyo PTFE, ma juyike pi tiyo ku piny matung tung man lyethu.

2. Ball Valve-Valve Seat Gasket

• Kabedo pa valve pa ball valve de utiye kit gasket, ma pol kare juyike ku piny macalo PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), nyo plastics ma juyubu.
• Emiyo cing ikum opira ku kum valve, ma tiyo calu cing ma ucungo (ma rwate ku kum valve) man cing ma ucungo (ma rwate ku opira ma lokore).

IV. Valve makani ma pol kare jutiyo kudu ngo ku gaskets?

1. Valves ma jukubo: Valve kum jukuru ikum pipeline, ma jwigo mitu pa flanges man gaskets.
2. Valves ku threaded connections: Gitiyo ku threaded sealing (macalu raw material tape nyo sealant), ma pol kare giweko mitu pa gaskets.
3. Monolithic valves: Valves moko ma wel migi lapiny nyo valve moko ma pire tek utiye ku valve body ma jucopo poko ngo, ento epe ku valve cover gasket.
4. Valves ku O-rings nyo gaskets ma jukubo ku cuma: I tic ma tek, lyethu ma malo, nyo tic ma pire tek, yore mi juku piny ma malu copo loko gaskets macon.

V. Lembe ma nok:

Valve gasket ubedo kit piny moko ma juku kudu, jutiyo kudu lee i pipeline mi mako valve matung tung, man de jutiyo kudu pi juku valve mapol. I yero, mitire ni yero piny maber pa gasket man ni yubu nimakere ku kit valve, yore mi mako, piny ma iye, lyethu man tegu.
