Valve Gasket hnathawh dan leh hman dan tur kaihhruaina

Valve gasket hi pressure, corrosion, leh component hrang hrangte inkara thermal expansion/contraction avanga leak awm lo tura siam a ni. Chutih laiin, a zawng zawng deuhthaw chu flanged an niconnection a ni' .s valve te hian gasket an mamawh a, an hmanna bik leh pawimawhna chu valve chi leh design a zirin a inang lo. Hemi \henah hian, .TWSvalve dahna tur hmun leh gasket material thlan dan tur a sawifiah ang.

I. Gasket hmanna ber chu valve connection flange joint-ah a ni.

Valve hman tlanglawn ber

1. Gate Valve a ni
2. Globe Valve hmanga siam a ni
3. Butterfly valve a ni(a bik takin concentric leh double eccentric flanged butterfly valve te chu)
4. Valve enfiah rawh

Heng valve-ah hian gasket hi flow regulation emaw valve chhunga sealing emaw atan hman a ni lo va, flange pahnih inkar (valve ngei flange leh pipe flange inkar) inkarah dah a ni. Bolt te kha tihkhauh a nih chuan clamping force tling tak siamin static seal siam a ni a, chu chuan connection-a medium leakage a veng thei a ni. A hnathawh chu metal flange surface pahnih inkara gap te te, inthlau lo tak takte chu a luah khat a, connection-ah 100% sealing a awm theih nan.

II.Valve “Valve Cover”-a Gasket hman dan.

Valve tam tak chu a chhunga enkawl awlsam zawk nan valve body leh cover hrang hrang neia siam an ni (eg, valve seat thlak, disc valve, emaw, bawlhhlawh paih te), chu chu bolt-in an inzawm khawm a ni. He connection-ah hian gasket pawh a ngai a, chu chu seal tight tak a nih theih nan a ni.

1. Valve cover leh gate valve leh globe valve valve body inzawmna atan hian gasket emaw O-ring emaw hman a ngai tlangpui.
2. Hetiang hmuna gasket hian static seal hna a thawk bawk a, chu chuan valve body atanga boruak chhunga medium a leak loh nan a pui bawk.

III. Valve chi hrang hrang tan gasket bik

Valve thenkhat chuan gasket hi an core sealing assembly-ah an dah tel a, valve structure chhunga inzawmkhawm tura duan an ni.

1. Butterfly valve a ni-valve thutna gasket a awm

• Butterfly valve seat hi a takah chuan ring gasket a ni a, chu chu valve body chhung lam bang chhungah press emaw, butterfly disc vel ah dah emaw a ni.
• Chutih lai chuan butterflydisc a nia khar a, valve seat gasket chu a press a, dynamic seal (butterfly angin) a siam a nidisc a nia inher chhuak).
• Material hi a tlangpuiin rubber (eg, EPDM, NBR, Viton) emaw PTFE emaw a ni a, media hrang hrang leh temperature condition hrang hranga siam a ni.

2. Ball Valve hmanga siam a ni-Valve Seat Gasket a awm bawk

• Ball valve valve seat pawh hi gasket chi khat a ni a, a tlangpuiin PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), emaw reinforced plastic ang chi thil atanga siam a ni.
• Ball leh valve body inkarah seal a siam a, static seal (valve body nena inzawm) leh dynamic seal (rotating ball nena inzawm) angin a thawk ve ve a ni.

IV. Eng valve nge gasket nena hman loh tlangpui?

1. Welded valve: Valve body chu pipeline-ah direct-in weld a ni a, flange leh gasket hman a ngai tawh lo.
2. Threaded connection nei valve: Threaded sealing (raw material tape emaw sealant ang chi) an hmang tlangpui a, a tlangpuiin gasket hman a ngai tawh lo.
3. Monolithic valve: Ball valve man tlawm tak tak emaw, specialized valve thenkhatah chuan integral valve body a awm a, chu chu tihchhiat theih a ni lo va, chuvangin valve cover gasket a tlachham a ni.
4. O-ring emaw metal-a khuh gasket nei valve: Pressure sang, temperature sang emaw special-medium emaw hmannaah chuan sealing solution hmasawn tak takte chuan non-metallic gasket hmanlai chu a thlak thei a ni.

V. Thupui tawi: 1.1.

Valve gasket hi general cutting key sealing element chi khat a ni a, flange valve hrang hrang pipeline connection-ah hman a ni nasa hle a, valve tam tak valve cover sealing-ah pawh hman a ni bawk. Selection-ah hian valve chi, connection mode, medium, temperature leh pressure a zirin gasket material leh form dik tak thlan a ngai a ni.
