Fixed Ball Valve

Isu tiri nyanzvi yekugadzira valve yakabata ISO, API uye CE certification. Isu pachedu midziyo yekugadzira yepamusoro uye yakazara seti yemhando yekudzora masisitimu. Isu tinogashirawo maOEM neODM maodha, ane inochinjika yakaderera odha huwandu. Zvigadzirwa zvedu zvakavimbika zvinotengeswa kunze kwenyika uye zvinokunda kuzivikanwa kwakakura kubva kune vatengi.

Chii chinonzi trunnion chakaiswa fixed bhora vharafu?

Trunnion yakagadzikwa bhora mavharuvhu akagadzirirwa kumanikidza yakakwira uye hombe dhayamita mapaipi. Kuenzaniswa nemavharuvhu ebhora anoyangarara, bhora rinovharirwa panzvimbo kuburikidza nepamusoro pevharuvhu hunde uye rezasi trunnion shaft. Inongotenderera pakuvhura nekuvhara pasina kukukurwa kana dzvinyiriro ichishanda. Iyo trunnion chimiro inotora yakawanda fluid pressure load, inonyatso kudzikisa friction pachigaro chekuisa chisimbiso. Iyi dhizaini inoita yakagadziriswa bhora mavharuvhu akanyanya kugadzikana uye anogara kwenguva refu inoenderera mberi maindasitiri kushanda.

Ndeupi musiyano uripo pakati peyakagadziriswa bhora vharafu uye inoyangarara bhora vharafu?

Uyu ndiwo mubvunzo unowanzo bvunzwa nevatengi vepasirese. Musiyano wepakati uri mune bhora rinotsigira chimiro uye kumanikidza kubereka maitiro.

Mavharuvhu ebhora anoyangarara haana yakaderera trunnion rutsigiro. Kana simba repombi rakwira, yepakati inosaidzira bhora zvakasimba kuchigaro chezasi. Izvi zvinogadzira kukwesha kukuru, torque yakakwira yekushandisa uye kupfeka nekukurumidza kwechigaro. Marudzi anoyangarara akakodzera chete saizi diki uye yakaderera kusvika yepakati kumanikidza kushanda mamiriro.

Fixed trunnion ball valves inogadzirisa bhora panzvimbo. Kuremerwa mutoro kunoitwa ne trunnion shaft uye kutakura kwemuviri, kwete chigaro chekuisa chisimbiso. Iyo inoratidzira yakaderera inoshanda torque, zvishoma chigaro abrasion, yakagadzikana yekuisa chisimbiso uye hupenyu hurefu hwesevhisi. Kune DN100 / NPS4 uye pamusoro pemapaipi makuru-akabereka kana akanyanya-kudzvanywa, mavharuvhu ebhora anogara ari sarudzo yekutanga muinjiniya yemaindasitiri.

Hunhu Hunokosha

Ndekupi kunogadziriswa mavharuvhu ebhora anowanzoshandiswa?

Trunnion fixed bhora mavharuvhu anoshandiswa zvakanyanya mune inorema-basa maindasitiri mamiriro anoda yakagadzikana chisimbiso uye refu sevhisi hupenyu. Maindasitiri akajairika anosanganisira mapaipi ekufambisa emafuta negasi, zvidyarwa zvepetrochemical, zviteshi zvemagetsi zvinopisa, mapurojekiti ekurapa mvura, zviteshi zvegasi rechisikigo uye masisitimu ekurebesa emvura mumaindasitiri. Inonyanya kukodzera mamiriro ekushanda ane high pressure, yakakura kuyerera, kuchinja nguva dzose uye zvakasimba zero-leakage zvinodiwa.

Ndezvipi zvinhu zvaunotsigira zvakagadziriswa bhora valve miviri uye zvikamu zvemukati?

Isu tinopa huwandu hwemuviri uye zvinhu zvemukati kuti zvienderane nemamiriro akasiyana ekushanda. WCB kabhoni simbi ndiyo sarudzo yedu yakajairika yemapaipi epaipi maindasitiri, kuendesa kusimba kwakavimbika pamutengo wemakwikwi. Nemasevhisi ane corrosive liquid kana gasi, tinosarudza CF8 (304) uye CF8M (316) simbi isina tsvina yekuvimbika ngura kuramba.

Isu tinokwanisawo kutora zvinhu zvakakosha zvakadai sesimbi yakadzika-tembiricha uye alloy simbi yehasha, inoda mapurojekiti.Kune zvikamu zvemukati zvakaita sebhora nezvigaro zvevharuvhu, isu tinokwanisa kugadzira misanganiswa yakasiyana zvichienderana nezvinodiwa zvako zvekushanda.Metal hard seal parts anowanikwa kune yakaoma kushanda mamiriro, ukuwo classic PTFE uye RPTFE zvinyoro zvisimbiso zvinopihwa kuti zvienderane zvinoenderana nezvinodiwa zveprojekiti.

Ndeapi zviyero uye zvitupa izvo mavharuvhu ako akagadzika ebhora anotevedzera?

Yese trunnion yedu yakaiswa yakagadziriswa bhora mavharuvhu anogadzirwa zvakanyatsoenderana neAPI 6D uye ASME B16.34 yepasirese zviyero. Fekitori yedu ine yakazara API, ISO uye CE certification. Yese yapera vharafu inopasa nyanzvi shell pressure test, seat tightness test uye air tightness test isati yasununguka. Yese mishumo yebvunzo uye magwaro etifiketi anogona kupihwa kutsigira vatengi kuongororwa kweprojekiti uye kubvumidzwa kwetsika.

Ndinofanira kusarudza chisimbiso chakapfava kana simbi chisimbiso yakagadziriswa bhora vharafu?

Zvinoenderana nepombi yako yepakati uye tembiricha yekushanda. Mavharuvhu ebhora akapfava-akagadzika anotora PTFE kana RPTFE yekuisa chisimbiso, kuwana bubble-tight zero leakage. Iwo akanakira mvura yakachena, gasi uye yakajairwa-tembiricha oiri yepakati ine yakasimba yekuisa chisimbiso zvinodiwa.

Metal yakaoma-yakavharwa yakagadziriswa bhora mavharuvhu anogona kuchinjika kune yakakwira tembiricha, yakakwira kudzvanywa uye yepakati ine diki diki diki. Iyo simbi-kune-simbi yekuisa chisimbiso chimiro inopfeka-inodzivirira uye yakakwirira-yekushisa inoshingirira, inoshandiswa zvakanyanya mukuomarara petrochemical uye yakakwirira-tembiricha pombi mamiriro.

Ko mavharuvhu ebhora akagadzika anogona kuve nemagetsi kana pneumatic actuators?

Hongu, zvizere customizable. Mavharuvhu edu akagadziriswa anogona kufananidzwa negiya rekushandisa, pneumatic actuators, magetsi emagetsi uye hydraulic actuators. Nekuda kweiyo trunnion rutsigiro chimiro, iyo torque yekushandisa yakadzikira zvakanyanya pane inoyangarara mavharuvhu ebhora. Iyo inogona kunyatso kudzikisa mutengo wekumisikidza weanoita uye kuve nechokwadi chakanyanya kugadzikana otomatiki kuvhura uye kuvhara kushanda.

Ndeipi yako yemhando vimbiso uye mushure mekutengesa mutemo?

Yese trunnion yedu yakaiswa yakagadziriswa bhora mavharuvhu anonakidzwa kwenguva refu yemhando waranti. Isu tinopa yakakwana tekinoroji rutsigiro, yekuisa kutungamira uye mushure mekutengesa kubvunza. Isu tinotarisa pahukama hwehukama hwenguva refu nevatengi vepasirese, kwete madhiri enguva imwe chete.
