Valve Gasket Basa & Chikumbiro Chekushandisa

Mavharuvhu gaskets akagadzirirwa kudzivirira kuvuza kunokonzerwa nekumanikidzwa, ngura, uye kuwedzera kwemafuta / kuputika pakati pezvikamu. Nepo dzinenge dzese flangedkubatana's mavharuvhu anoda gaskets, kushandiswa kwavo chaiko uye kukosha kunosiyana nerudzi rwevharuvhu uye magadzirirwo. Muchikamu chino,TWSichatsanangura nzvimbo dzekuisa valve uye kusarudzwa kwezvinhu zvegasket.

I. Iko kushandiswa kwekutanga kwegaskets kuri pajojo yeflange yekubatanidza mavharuvhu.

Inonyanya kushandiswa valve

1. Gedhi Vavhavha
2. Globe Valve
3. Butterfly valve(kunyanya iyo concentric uye kaviri eccentric flanged butterfly valve)
4. Tarisa vharafu

Mune mavharuvhu aya, iyo gasket haishandiswe pakuyerera kwekuyerera kana kuvhara mukati mevhavha pachayo, asi yakaiswa pakati pemaflange maviri (pakati peiyo flange yevhavha pachayo uye pombi flange). Nekuomesa mabhaudhi, simba rekusunga rakakwana rinogadzirwa kugadzira chisimbiso chakamira, kudzivirira kubuda kwepakati pakubatanidza. Basa rayo nderekuzadza madiki asina kuenzana pakati pemasimbi maviri esimbi flange, kuve nechokwadi che100% chisimbiso pakubatanidzwa.

II.Kushandiswa kweGasket muValve "Valve Cover"

Mavharuvhu mazhinji akagadzirwa aine miviri yevharuvhu yakaparadzana uye anovhara kuitira nyore kugadzirisa mukati (semuenzaniso, kutsiva zvigaro zvevharuvhu, mavharuvhu edhisiki, kana marara ekubvisa), ayo anobva asungwa pamwechete. Gasket inodiwawo pakubatanidza uku kuti ive nechokwadi chekusimbisa chisimbiso.

1. Kubatana pakati pevhavha yevhavha uye muviri wevhavha yevhavha yegedhi nevhavha yeglobe inowanzoda kushandiswa kwegasket kana O-ring.
2. Iyo gasket iri pachinzvimbo ichi inoshandawo sechisimbiso chakamira kudzivirira yepakati kubva pakudonha kubva kumuviri wevharuvhu kuenda mumhepo.

III. Special gasket yemhando dzevharuvhu chaiyo

Mamwe mavharuvhu anosanganisira gasket sechikamu chepakati yavo yekuisa chisimbiso musangano, yakagadzirirwa kubatanidzwa mukati meiyo valve chimiro.

1. Butterfly valve-vhavha chigaro gasket

• Chigaro chevhavhavhavhavha chinenge chiri chindori gasket, chinotsikirirwa mukati memadziro evharuvhu muviri kana kuiswa kutenderedza butterfly disc.
• Kana shavishavidiscinovhara, inodzvanya chigaro chevhavha gasket kuti iite chisimbiso chine simba (seshavishavidiscinotenderera).
• Izvo zvinhu zvinowanzoita rabha (semuenzaniso, EPDM, NBR, Viton) kana PTFE, yakagadzirirwa kugarisa akasiyana midhiya uye tembiricha mamiriro.

2. Bharavhavha-Valve Seat Gasket

• Chigaro chevhavha yevhavhavha yebhora zvakare imhando yegasket, inowanzogadzirwa kubva kune zvinhu zvakaita sePTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), kana mapurasitiki akasimbiswa.
• Inopa chisimbiso pakati pebhora nemuviri wevhavha, kushanda zvose sechisimbiso chakasimba (chinoenderana nemuviri wevhavha) uye chisimbiso chine simba (chinoenderana nebhora rinotenderera).

IV. Ndeapi mavharuvhu asingawanzo kushandiswa negaskets?

1. Welded mavharuvhu: Muviri wevharuvhu wakasungirirwa zvakananga kune pombi, kubvisa kudiwa kwemaflange uye gaskets.
2. Mavharuvhu ane tambo dzekubatanidza: Ivo vanowanzo shandisa chisimbiso chine shinda (senge mbishi tepi kana sealant), kazhinji kubvisa kudiwa kwemagaskets.
3. Monolithic mavharuvhu: Mamwe mavharuvhu anodhura-akaderera kana mavharuvhu akasarudzika ane muviri wakakosha wevharuvhu usingagone kuparadzaniswa, nekudaro kushaya chivharo chevhavha gasket.
4. Mavharuvhu ane O-mhete kana simbi-yakaputirwa gaskets: Mupamusoro-kudzvanywa, yakakwirira-tembiricha, kana yakakosha-yepakati maapplication, epamberi yekuisa chisimbiso mhinduro dzinogona kutsiva dzakajairwa dzisiri-metallic gaskets.

V. Pfupiso:

Valve gasket imhando yeyakajairwa yekucheka kiyi yekuisa chisimbiso chinhu, inoshandiswa zvakanyanya mukubatanidza pombi yeakasiyana mavharuvhu eflange, uye inoshandiswawo muvhavhavhavha yekuvharira chisimbiso chevhavha zhinji. Mukusarudza, zvinodikanwa kusarudza iyo yakakodzera gasket zvinhu uye fomu zvinoenderana nerudzi rwevhavha, yekubatanidza modhi, yepakati, tembiricha uye kumanikidza.
