Ukuhlukaniswa Okusemqoka kanye Nezimo Zesevisi Yezinto Zokubopha I-Valve

Ukubekwa uphawu kwe-valve kuyingxenye ebalulekile ye-valve yonke, inhloso yayo eyinhloko ukuvikela ukuvuza,I-valveIsihlalo sokufaka uphawu sibizwa nangokuthi indandatho yokuvala uphawu, yinhlangano exhumana ngqo ne-medium epayipini futhi ivimbele okuphakathi kokugeleza. Lapho i-valve isetshenziswa, kunemidiya ehlukahlukene epayipini, njenge-liquid, igesi, uwoyela, imithombo yezindaba eqinile, njll., Kanye nezimpawu zama-valve ahlukene zisetshenziswa ezindaweni ezahlukahlukene futhi zingazivumelanisa nezimo ezahlukahlukene.

I-TWSVvalaUkukhumbuza ukuthi izinto zokwenziwa kwezimpawu ze-valve zingahlukaniswa izigaba ezimbili, okungukuthi izinto zensimbi nezinto ezingezona zensimbi. Izilongeli ezingezona zensimbi zivame ukusetshenziswa kumapayipi okushisa okujwayelekile kanye nengcindezi, kanti izilondolozi zensimbi zinobubanzi bezicelo ezibanzi futhi zingasetshenziswa emazingeni okushisa aphezulu. ingcindezi ephezulu.

1. Zokwenziwa irabha

Irabha yokwenziwa lingcono kunerabha yemvelo ngokuya ngokumelana kawoyela, ukumelana nokushisa kanye nokuphikiswa kokugqwala. Ngokuvamile, izinga lokushisa elisebenzayo lerabha yokwenziwa≤I-150°C, irabha lemvelo t≤60°C, futhi irabha isetshenziselwa ukubekwa uphawu kwama-valves omhlaba, ama-valves wesango, ama-valves we-diaphragm, ama-butterfly ama-valves, hlola ama-valves, i-pinve valves namanye ama-valves anengcindezi yokuqothuka≤I-1MPA.

2. I-Nylon

I-Nylon inezimpawu zokuphikiswa okuncane kwezingxabano kanye nokuphikiswa okuhle kokugqwala. I-nylon isetshenziselwa kakhulu ama-valves webhola kanye nama-valves emhlabathini anokushisa t≤90°C kanye nengcindezi yokuqothuka PN≤32MPA.

3. Polytetrafluoroethylelene

I-PTFE isetshenziselwa kakhulu ama-globe valves, ama-valves e-Gate, ama-valves e-njll. Ngokushisa T≤232°C kanye nengcindezi yokuqothuka pn≤I-6.4MPA.

4.

I-Cast Iron isetshenziselwa ama-valves ama-Gate, ama-valves we-Globe, ama-plex valves, njll. Ukushisa T≤100°C, ingcindezi yokuphakama pn≤I-1.6MPA, igesi newoyela.

5. I-Babbitt Alloy

I-Bablitt Alloy isetshenziselwa i-ammonia hlaba i-valve ngokushisa T-70 ~ 150℃kanye nengcindezi yokuzithiba≤I-2.5MPA.

6. I-Copper Alloy

Izinto ezisetshenziswayo ezisetshenziswayo zama-alloys zethusi zingama-6-6 kaTin Bronze kanye ne-58- 2 Manganese yethusi. I-Copper Alloy inokumelana okuhle kokuvimbela futhi ilungele amanzi nomusi ngokushisa T≤-Mashumi℃kanye nengcindezi yokuzithiba≤1.6MPA. Imvamisa isetshenziswa kuma-valves wesango, ama-valves we-Globe, hlola ama-valves, ama-plex valves, njll.

7. Insimbi ye-Chrome engenasici

Amamaki asetshenziswa kakhulu wensimbi ye-chromium engagqwali ayi-2CR13 ne-3CR13, ecinyiwe futhi eshubile, futhi ibe nokuphikiswa okuhle kokugqwala. Imvamisa isetshenziswa kuma-valves amanzi, umusi kanye nophethiloli ngokushisa t≤I-450℃kanye nengcindezi yokuzithiba≤32MPA.

8. I-Chrome-Nickel-Tickel-Titanium Engagqwali

Ibanga elisetshenziswa kaningi le-chromium-nickel-titanium-titanium esingenacala yi-1CR18NI9TI, enokumelana kahle nokuphikiswa, ukumelana nokuguguleka kanye nokuphikiswa kokushisa. Ilungele umusi nakweminye imidiya nge-trampete t≤I-600°C kanye nengcindezi yokuqothuka pn≤I-6.4MPA, futhi isetshenziselwa ama-valves e-Globe valves, ama-valve ebhola, njll.

9. Insimbi Enriding

Ibanga elisetshenziswa kakhulu lensimbi ye-nitriding yi-38crmoala, elinokumelana kahle nokugqwala nokumelana kokulwa ngemuva kokulashwa. Ivame ukusetshenziswa emavalomu esiteshini sesiteshi samandla ngokushisa t≤540℃kanye nengcindezi yokuzithiba≤10MPA.

10. UCoroning

Ukubopha ngokuqondile kucubungula indawo yokubopha uphawu kusuka ezintweni zomzimba we-valve noma umzimba we-disc, bese wenza ukwelashwa okukhohlisayo. Indawo yokubopha uphawu inokuvimbela okuhle. Ukuze uthole i-valve ye-Power Slowdown.

Lapho i-valve isetshenziswa, izindaba okufanele zinakeke kakhulu ezikulandelayo:

1. Ukusebenza kokubekwa uphawu kwe-valve kufanele kuhlolwe ukuze kuqinisekiswe ukusebenza kwawo.
