Giya ed Uusaren tan Pangusar na Valve Gasket

Saray gasket na balbula et adesinyo pian ag-onleak lapud pressure, corrosion, tan thermal expansion/contraction ed baetan na saray kabiangan. Bangta ngalngalin amin et walay flangekoneksyon's saray balbula et mankaukolan na gasket, say espisipikon aplikasyon tan kaimportantian da et manduruma depende ed klase tan desinyo na balbula. Diad sayan seksion,TWSipaliwawa to ray posisyon na pangipuesto na balbula tan say pampili na materyales na gasket.

I. Say manunan uusaren na saray gasket et diad flange joint na saray koneksyon na balbula.

Say kaslakan ya uusaren ya balbula

1. Gate Valve
2. Globe Valve
3. Balbula na kulibangbang(lalo la ed concentric tan double eccentric flanged butterfly valve)
4. Check valve

Diad sarayan balbula, say gasket et ag-uusaren parad regulasyon na agos odino panag-seal ed loob na mismon balbula, noagta iiyan ed baetan na duaran flange (diad baetan na flange na mismon balbula tan say flange na tubo). No ipeket iray bolt, nawalaan na magenap a puersa na panag-ipit pian makagawa na ag-onkukurang a seal, ya ag-onleak so medium diad koneksion. Say gagala to et panoen iray angkekelag ya ag-apantay ya gap ed baetan na duaran metal ya tapew na flange, pian naseguro so 100% ya inkaseal ed koneksion.

II.Pangusar na Gasket ed Valve "Valve Cover"

Dakel a balbula so adesinyo a walaan na nanduruman laman na balbula tan sakbong pian mas mainomay so panmintina ed loob (alimbawa, pangisaliwan na yurongan na balbula, balbula na disc, odino pangekal na saray debris), ya insan ira i-bolt. Kaukolan met so gasket ed sayan koneksyon pian naseguro ya malet so seal to.

1. Say koneksion na sakbong na balbula tan say laman na balbula na gate valve tan say globe valve et kaslakan ya mankaukolan na gasket odino O-ring.
2. Say gasket ed sayan posisyon et manseserbi met ya static seal pian ag-onlelereg so medium manlapud laman na balbula ya onloob ed atmospera.

III. Espisyal ya gasket parad espisipikon klase na balbula

Wala ray balbula ya mangilaktip na gasket bilang kabiangan na core sealing assembly da, ya adesinyo pian niiyan ed loob na istruktura na balbula.

1. Balbula na kulibangbang-valve seat gasket

• Say yurongan na butterfly valve et sakey a ring gasket, ya akapeket ed loob na dingding na laman na balbula odino akapeket ed kaliberliber na butterfly disc.
• Nen say kulibangbangdiscmansara, pindoten to so gasket na yurongan na balbula pian nawalaan na dinamikon selyo (singa say kulibangbangdiscmanpapawilpawil).
• Say materyales et kaslakan ya goma (alimbawa, EPDM, NBR, Viton) odino PTFE, ya adesinyo pian naakomodar so nanduruman kondisyon na media tan temperatura.

2. Ball Valve-Valve Seat Gasket

• Say valve seat na ball valve et sakey met a klase na gasket, ya kaslakan et gawad materyales a singa say PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), odino pinabiskeg iran plastik.
• Saya so mangiiter na seal ed baetan na bola tan say laman na balbula, ya manseserbin parehon static seal (no ikompara ed laman na balbula) tan dynamic seal (no ikompara ed manbabaroy a bola).

IV. Anto ran balbula so ag tanton uusaren ed saray gasket?

1. Welded valves: Say laman na balbula et direktan i-weld ed pipeline, kanian agla kaukolan so flanges tan gaskets.
2. Saray balbula ya walay threaded connections: Kaslakan et manguusar ira na threaded sealing (singa say raw material tape odino sealant), ya kaslakan et agla kaukolan so gasket.
3. Monolithic valves: Wala ray abeban presyo ya ball valves odino specialized valves ya walay integral valve body ya ag nayarin i-disassemble, kanian anggapoy valve cover gasket.
4. Saray balbula ya walay O-ring odino metal-wrapped gaskets: Diad high-pressure, high-temperature, odino special-medium ya aplikasyon, saray advanced sealing solutions et nayarin onsalat ed saray kombensional ya aliwan metal ya gasket.

V. Sumaryo:

Say valve gasket et sakey a klase na general cutting key sealing element, saya so malaknab ya uusaren ed pipeline connection na nanduruman flange valves, tan uusaren met ed valve cover sealing na dakel a balbula. Diad panagpili, kaukolan ya pilien so manepeg ya materyales na gasket tan porma unong ed klase na balbula, paraan na koneksyon, medium, temperatura tan presyon.
