Wɔ ɔfã yi mu no, .TWSbɛkyerɛkyerɛ valve a wɔde besisi gyinabea ne gasket nneɛma a wɔpaw mu.

I. Gaskets a wɔde di dwuma titiriw ne flange joint a ɛwɔ valve nkitahodi ahorow no mu.

Valve a wɔtaa de di dwuma kɛse

1. Gate Valve a ɛwɔ hɔ
2. Globe Valve a Wɔde Yɛ Nneɛma
3. Nwansena valve(titiriw concentric ne double eccentric flanged ntontom valve no)
4. Hwɛ valve no mu

Wɔ saa valve ahorow yi mu no, wɔmfa gasket no nni dwuma mma flow regulation anaasɛ sealing wɔ valve no ankasa mu, na mmom wɔde si flanges abien ntam (wɔ flange a ɛwɔ valve no ankasa ne pipe flange ntam). Ɛdenam nkɔnsɔnkɔnsɔn no a wɔkyekyere no denneennen so no, wɔma ahoɔden a ɛdɔɔso a ɛkyekyere no ba ma ɛyɛ static seal, na ɛmma medium no ntumi nkɔ baabi a ɛka bom no. Ne dwumadie ne sɛ ɛbɛhyɛ nsonsonoeɛ nketenkete a ɛnyɛ pɛpɛɛpɛ a ɛda dadeɛ flange afã mmienu no ntam no ma, ahwɛ ahu sɛ ɛbɛsɔ 100% wɔ nkitahodiɛ no so.

II.Gasket a Wɔde Di Dwuma wɔ Valve “Valve Cover” mu .

Wɔayɛ valve pii a ɛwɔ valve nipadua ne nkataso ahorow a ɛsono emu biara sɛnea ɛbɛyɛ a ɛbɛyɛ mmerɛw sɛ wobesiesie mu (sɛ nhwɛso no, wɔbɛsesa valve nkongua, disc valve, anaasɛ wɔbɛpopa nneɛma a asɛe), a afei wɔde bolt abɔ mu. Ɛsɛ sɛ wɔde gasket nso hyɛ saa nkitahodi yi so na ama wɔahwɛ ahu sɛ wɔde nsɔano a ɛyɛ den ahyɛ mu.

1. Nkitahodi a ɛda valve no kataso ne valve nipadua a ɛwɔ gate valve no ne globe valve no ntam no taa hwehwɛ sɛ wɔde gasket anaa O-ring di dwuma.
2. Gasket a ɛwɔ saa gyinabea yi nso yɛ adwuma sɛ static seal na amma medium no antu mfi valve nipadua no mu akɔ wim.

III. Gasket titiriw ma valve ahorow pɔtee bi

Valve ahorow bi de gasket no ka ho sɛ wɔn core sealing assembly no fã, a wɔayɛ sɛ wɔde bɛka valve nhyehyɛe no ho.

1. Nwansena valve-valve nkongua gasket

• Butterfly valve no nkongua yɛ ring gasket ankasa, a wɔde mia kɔ valve no nipadua no mu ɔfasu mu anaasɛ wɔde si ntontom disc no ho.
• Bere a ɔkɔre nodiscsɛ ɛto mu a, ɛmia valve seat gasket no mu ma ɛyɛ nsɔano a ɛyɛ nnam (sɛ ɔkɔre nodiscdi akɔneaba).
• Adeɛ no taa yɛ rɔba (sɛ nhwɛsoɔ no, EPDM, NBR, Viton) anaa PTFE, a wɔayɛ sɛ ɛbɛfa nsɛm ho amanneɛbɔ ne ɔhyeɛ tebea ahodoɔ.

2. Bɔɔl Valve-Valve Nkongua Gasket

• Valve nkongua a ɛwɔ bɔɔl valve mu nso yɛ gasket bi, a wɔtaa de nneɛma te sɛ PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), anaa plastic a wɔahyɛ no den na ɛyɛ.
• Ɛma nsɔano bi ba bɔɔl no ne valve nipadua no ntam, na ɛyɛ nsɔano a ɛnyɛ hwee (sɛ wɔde toto valve nipadua no ho) ne nsɔano a ɛyɛ nnam (sɛ wɔde toto bɔɔl a ɛkyinkyini no ho).

IV. Valve bɛn na wɔtaa mfa nni dwuma wɔ gasket ho?

1. Valve a wɔde weld ayɛ: Wɔde weld afra valve nipadua no so tẽẽ kɔ nsu afiri no mu, na ɛmma enhia sɛ wɔde flanges ne gaskets di dwuma.
2. Valve a wɔde nhama ayɛ: Wɔtaa de nhama a wɔde hyɛ mu (te sɛ raw material tape anaa sealant) di dwuma, mpɛn pii no ɛmma enhia sɛ wɔde gasket hyehyɛ mu.
3. Monolithic valves: Ball valve ahorow bi a ne bo nyɛ den anaa valve soronko bi wɔ valve nipadua a ɛyɛ biako a wontumi npaapae mu, ma enti enni valve kataso gasket.
4. Valve a O-rings anaa gasket a wɔde dade abɔ ho: Wɔ nhyɛso kɛse, ɔhyew a ɛkɔ soro, anaa soronko-mfinimfini dwumadie mu no, nsɔano ano aduru a ɛkɔ anim betumi asi gasket a ɛnyɛ dade a wɔtaa de di dwuma ananmu.

V. Nsɛm a Wɔaboaboa Ano:

Valve gasket yɛ ɔkwan bi so a general cutting key sealing element, wɔde di dwuma kɛse wɔ pipeline nkitahodi a ɛwɔ flange valves ahorow mu, na wɔde di dwuma nso wɔ valve cover sealing a ɛwɔ valve pii mu. Wɔ paw mu no, ɛho hia sɛ wɔpaw gasket ade a ɛfata ne ɔkwan a wɔfa so yɛ sɛnea valve no su, nkitahodi kwan, mfinimfini, ɔhyew ne nhyɛso te.
