Gwaro reZvigaro zveVharuvhu Yebhora: Chombo Chakavanzika cheChisimbiso Chako

Gwaro reChigaro cheVharuvhu yeBhora: Mabasa, Zvishandiso (Chigaro chePTFE & Zvimwe) & Matanho eTembiricha | Chisimbiso Chekupedzisira

Munyika yemavharuvhu ebhora, kusimbisa chisimbiso chinoshanda ndicho chinhu chakakosha. Pakati pebasa iri rakakosha pane chinhu chakakosha:Chigaro cheVharuvhu yeBhora, inowanzonzi cheteChigaro cheVharuvhuGamba iri risingaimbwe ndiro "mhare yekusimbisa" yeBall Valve assembly.

Chii chaizvo chinonzi Ball Valve Seat?

IyoChigaro cheVharuvhu yeBhorachinhu chakakosha chekuvhara mukati mevharuvhu yebhorachimiro. Kazhinji yakagadzirwa nesimbi kana zvinhu zvisiri zvesimbi, inoiswa mukati memuviri wevharuvhu. Basa rayo guru nderekugadzira chivharo chakasimba chekuvhara bhora rinotenderera. Nekuchengetedza kubatana uku kwepedyo,Chigaro cheVharuvhuinogonesa vharuvhu kudzima kana kudzora kufamba kwemvura nenzira yakavimbika.

Kutyisidzira Kutatu kweChigaro cheValve: Kupfuura Chisimbiso Chete

Yemazuva anoZvigaro zveVharuvhu yeBhoravane hunyanzvi hunoshamisa kupfuura kusimbisa kwekutanga:

1. Kuvhara Kunochinjika (Shape-Shifter):Kufanana nepiro yefuro rekurangarira rinoenderana nemusoro wako, Chigaro cheValve chemhando yepamusoro chinochengetedza kutwasuka kwechinhu chero chipi zvacho pakupisa kwakanyanya (zvichienderana neASTM D1710 standards, kazhinji -196°C kusvika +260°C). Kutwasuka uku kunoita kuti chikwanise kutsiva otomatiki kusakara kudiki pamusoro pebhora, zvichiita kuti chive chakasimba kwenguva refu.

2. Mutungamiriri weFluid (Mudziviriri):Magadzirirwo akagadzirwa neunyanzvi, akadai seV-port Ball Valve Seats, anotungamira nzira inoyerera. Kuyerera uku kwakanangana kunobatsira kutsvaga nzvimbo dzinovhara, kudzivirira kuungana kwemarara kana tunhu tudiki tunogona kukanganisa chisimbiso.

3. Mubatsiri weNjodzi (Kuchengetedzwa kweMoto):Mamwe magadzirirwo eValve Seat ane zvinhu zvisingadziviriri moto. Kana paine kupisa kwakanyanya (senge moto), zvigaro izvi zvakagadzirwa kuti zvitsve kana kuti zvitsve. Rutivi urwu rwakatsveyamiswa runobva rwagadzira chisimbiso chechipiri, chekukurumidza kubva kusimbi kuenda kusimbi, zvichidzivirira kutadza kushanda zvakanaka.

Sainzi yeKuvhara: Mashandiro Echigaro cheVharuvhu

Kuvhara kunoitika kuburikidza nekudzvanya zvakananga. Kana bhora ratenderera panzvimbo yakavharwa, rinodzvanya zvakasimba paChigaro cheVharuvhu yeBhoraKudzvanywa uku kunochinja chigaro zvishoma, zvichiita kuti pave nechinodzivirira kuti chisadonhe. Mavharuvhu ebhora akajairika anoshandisa Zvigaro zviviri zveValve - chimwe chiri panzvimbo inopinzwa uye chimwe chiri parutivi rwekubuda. Kana zvakavharwa, zvigaro izvi zvinonyatso "gumbatira" bhora, zvichikwanisa kutsungirira kudzvanywa kusvika ku16MPa (paMaitiro eAPI 6DMagadzirirwo akagadziridzwa, akadai sezvigaro zveV-port, anogona kuwedzera kuvandudza kuvharwa kwechidzitiro kuburikidza nemasimba ekuchekerera anodzorwa anoshanda pamichina.

Matembiricha echigaro cheVharuvhu yeBhora: Zvinhu Zvinokosha

Miganhu yekushanda kwekushisa kweChigaro cheVharuvhu yeBhoraZvinoenderana nekugadzirwa kwezvinhu zvacho. Heino kupatsanurwa kwezvinhu zvechigaro chakajairika uye mwero wazvo wekupisa:

Zvigaro zveVharuvhu yeBhora reChisimbiso Chinyoro (Zvakavakirwa paPolymer & Elastomer):

•Chigaro chePTFE (Polytetrafluoroethylene):Sarudzo yekare. Zvigaro zvePTFE zvine simba rekudzivirira ngura uye zvinoshanda zvakanaka pakati pe-25°C kusvika +150°C. Kune mashandisirwo anoda nguva nenguva anoda kutenderera mabhasikoro, PTFE yakagadzirwa nemazvoZvigaro (zvichikwanisa kushivirira ±0.01mm) zvakabatanidzwa nemabhora akapedzwa zvakakwana zvinogona kupa macircuits anopfuura 100,000 pasina kubuda kwemvura - zvichizadzisa ISO 5208 Class VI seal standard yakasimba.

• PCTFE (Polychlorotrifluoroethylene):Yakanakira masevhisi e cryogenic. Inoshanda zvinobudirira kubva-196°C kusvika +100°C.

• RPTFE (PTFE Yakasimbiswa):Yakagadziridzwa kuti igare kwenguva refu uye tembiricha yakakwira. Nzvimbo yakakodzera:-25°C kusvika +195°C, yakanakira kushandiswa kwemagetsi akawanda.

• PPL (Polyphenylene):Inoshanda zvakanaka pakushandisa steam. Shandisa mukati-25°C kusvika +180°C.

• Viton® (FKM Fluoroelastomer):Inozivikanwa nekuda kwekusagona makemikari uye kugona kupisa zvakanyanya (-18°C kusvika +150°CShandisa nokungwarira neutsi/mvura.

• Silicone (VMQ):Inopa kusvika kwepamusoro-soro uye kusashanda kwemakemikari (-100°C kusvika +300°C), kazhinji zvinoda kurapwa mushure mekupora kuti uve nesimba rakakwana.

• Buna-N (Nitrile Rubber – NBR):Sarudzo inoshandiswa zvakasiyana-siyana uye isingadhuri yemvura, mafuta, uye mafuta emoto (-18°C kusvika +100°CKudzivirira kukwenywa zvakanaka.

• EPDM (Ethylene Propylene Diene Monomer):Yakanakira kudzivirira ozone, mamiriro ekunze, uye kushandiswa kweHVAC (-28°C kusvika +120°CDzivisa mahydrocarbon.

• MOC / MOG (Ma PTFE Composites Akazadzwa neCarbon):Inopa kugadzikana kwakawedzerwa uye kuramba kupfeka. MOC/MOG inowanzo kuvepo.-15°C kusvika +195°C.

• MOM (PTFE Yakagadziriswa Yakazadzwa neKabhoni):Yakagadzirirwa kupfeka, dhayagiramu-15°C kusvika +150°C.

• PA6 / PA66 (Nylon):Yakanakira kumanikidzwa uye kupfeka (-25°C kusvika +65°C).

• POM (Acetal):Simba guru uye kuomarara (-45°C kusvika +110°C).

• TARISA (Polyetheretherketone):Polima yepamusoro-soro inoshanda zvakanaka. Tembiricha inoshamisa (-50°C kusvika +260°C), kumanikidzwa, kupera, uye kusashanda nemakemikoro. Inodzivirira zvakanyanya hydrolysis (mvura inopisa/utsi).

Zvigaro zveValve yeBhora reChisimbiso Chakaoma (Chesimbi & Chigadzirwa cheAlloy):

• Simbi Isina Chinovhara + Tungsten Carbide:Mushonga wakasimba wekupisa kwakanyanya (-40°C kusvika +450°C).

• Hard Alloy (semuenzaniso, Stellite) + Ni55/Ni60:Kupfeka kwepamusoro uye kuramba kupisa kwakanyanya (-40°C kusvika +540°C).

• Chishongo chemafuta chinodziya zvakanyanya (semuenzaniso, Inconel, Hastelloy) + STL:Yakagadzirwa kuti ishandiswe zvakanyanya (-40°C kusvika +800°C).

Kufunga Zvakakosha:Zvinhu zvakanyorwa pamusoro apa zvinomiririra sarudzo dzakajairika.Chigaro cheVharuvhu yeBhorakusarudzwa kunofanirwa kuenderana nemamiriro chaiwo ekushanda(tembiricha, kumanikidzwa, pakati nepakati, frequency yekutenderera, nezvimwewo) yekushandiswa kwega kwega. Kune zvimwe zvinhu zvakawanda zvakagadzirwa kuti zvizadzise zvinodiwa zvakasiyana kunze kwetembiricha chete. Nguva dzose bvunza vagadziri vemavharuvhu kuti uwane mazano chaiwo ezvinhu zvakagadzirwa zvinoenderana nesystem yako. Kodzero yacho ndeyekushandisa.Chigaro cheVharuvhuzvakakosha kuvharuvhu yebhoramashandiro uye hurefu hwebasa.
