- I-ARAN yenza i-Trunnion Ball Valves ifumaneka kuluhlu olubanzi loyilo, izixhobo, ubungakanani kunye neeklasi zoxinzelelo kwaye zihambelana ngokupheleleyo nemigangatho yemveliso yamazwe ngamazwe ANSI, ASME B16.34, API 6D, ISO17292, GOST, DIN/EN iinkcukacha njl.
- I-valve yebhola ye-Trunnion inomlinganiselo omkhulu wokuvelisa i-Class 150 ~ Class 2500, PN16 ~ PN420, izinto ezahlukeneyo zisetyenziselwa ukuthutha amanzi / umphunga / i-oyile kunye namashishini egesi, ingaba nobushushu obuphantsi kunye neemeko zesicelo soxinzelelo oluphezulu, iimveliso ezifanelekileyo ezifana ne-nitric acid, i-acetic acid, i-oxidizing media, urea, njl.
- Iivalve zebhola ze-trunnion zisetyenziswa ngokubanzi ekucoceni i-petroleum, imibhobho emide, ishishini lemichiza, ukwenza iphepha, amayeza, ukugcinwa kwamanzi, amandla ombane, ulawulo lukamasipala, intsimbi kunye nezinye iindawo njl.
Ithini ingcaciso yevalvu yebhola yeTrunnion?
- Ivalve yebhola yetrunnion yivalve ejika ikota kwaye uyilo lwetrunnion luthetha ukuba ukudityaniswa kwebhola kuxhaswa yitrunion yenkxaso esezantsi kunye nesikhondo esiphezulu esiphezulu kwigumbi levalve yebhola.Olu yilo lubizwa ngokuba yi-trunnion valve yebhola efakwe kwi-trunnion okanye ivalve yebhola ye-trunnion.
- Ivalve yebhola ye-trunnion idla ngokusetyenziselwa ubungakanani obukhulu kunye nokusebenza kwevalve ephezulu yoxinzelelo, kunye nokunciphisa itorque yevalve ukuze isebenze lula.
- Isiqu esifakwe kwi-trunnion sithatha i-thrust ukusuka kuxinzelelo lomgca, ukuthintela ukukhuhlana okugqithisileyo phakathi kwebhola kunye nezihlalo, ngoko ke i-torque esebenzayo yevalve ihlala iphantsi kuxinzelelo olulinganisiweyo olupheleleyo.
- Ingaba isihlalo sevalve yebhola yetrunnion sitywinwa njani?
- Ukutywinwa kufumaneka ngezihlalo zohlobo lwepiston elayishiweyo ezivalela ukuphuma kwamanzi xa uxinzelelo lomgca lusebenza kwisitulo esinyukayo.Ukukhululeka okuzenzekelayo komngxuma phezu koxinzelelo kuqinisekiswa ngenxa yoyilo lwe-trunnion kwimeko yezihlalo zokuzikhulula.Ibhola iqhutywa yintambo yokusonta etywiniweyo apho umqhubi ancanyathiselwe.Iivalvu zebhola zenzelwe ukuba zisetyenziswe njengezixhobo zokulawula ukuqukuqela kokuvula/ukuvala kwaye akufunekanga zisetyenziselwe ukucudisa ukuqukuqela kolwelo.Iivalvu kufuneka zihlale zivuliwe okanye zivaliwe ngokupheleleyo.
- Uyilo lwezihlalo zevalve yebhola yeTrunnion zineempawu zoyilo ezibalulekileyo kwiimfuno ezahlukeneyo zesicelo:
- ● IZIHLALO EZIZIKHULULELAYO / IZIHLALO EZINYE (SPE) kunye ne-DOUBLE PISTON EFFECT SEATS (DEP)
- ● Uyilo lwezihlalo ze-DBB kunye ne-DIB
- Ibhola yevalve yetrunnion ilungisiwe kodwa izihlalo ziyabhetyebhetye.Isihlalo sine-SELF RELIEVING SEATES/SINGLE RELIEF SEATS (SPE) kunye noyilo lwe-DOUBLE PISTON EFFECT SEATS (DEP).Uyilo lwe-SPE yindlela enye yokutywinwa kwe-uni-directional kunye ne-DEP kukutywinwa kwe-bi-direction, nge-API 6D / ISO 14313 ichaza.
- I-ARAN isebenzisa ivalve yebhola ye-trunnion eyenzelwe izihlalo zesitulo esinye soncedo SPE-SPE kunye nebhloko ephindwe kabini kunye ne-DBB yokopha njengemveliso eqhelekileyo.Kodwa ezinye iintlobo zezihlalo zoyilo nazo ziyafumaneka ngesicelo esithile.
- Iimpawu zeSitulo esinye sePiston Effect Seat
- Izihlalo zeevalvu zebhola zicinezelwe ebholeni ngomthwalo wentwasahlobo.
- Njengoko uxinzelelo lomzimba womzimba lukhula ngaphezu komthwalo wasentwasahlobo, izihlalo zityhalwa ngasemva kwaye uxinzelelo lukhutshwa kumgca.Oku kubizwa ngokuba yi-single-piston effect (uxinzelelo kwi-cavity yomzimba yiyona parameter esebenzayo kuphela) .Ukukhululeka kwe-Cavity ukuya kwicala elisezantsi, ukuba zombini izihlalo zevalve yebhola ziyi-single-piston effect design.Isitulo ngasinye sizikhulula ngokwaso umngxuma womzimba phezu koxinzelelo kumgca.
- Umzobo: Uyilo lweSitulo esinye sePiston
- Iimpawu zoYilo lweSitulo sePiston ephindwe kabini
- Kolu yilo lwesitulo, uxinzelelo oluphakathi, kunye noxinzelelo lwecango yomzimba, ludala ukutyhala okutyhala amakhonkco esitulo kwibhola.Oku kubizwa ngokuba yi-double piston effect (uxinzelelo kumbhobho kunye nokuba kumgodi womzimba zombini iiparameters ezisebenzayo) .IiValve zeBhola ezinolu yilo zifuna isixhobo sokunciphisa uxinzelelo lomgodi ukunciphisa uxinzelelo lomzimba womzimba.
- Umzobo: Ukuyilwa kweSitulo sePiston Effect kabini
- Ivalve ye-Trunnion Ball DBB kunye ne-DIB izihlalo zenkcazo yoyilo
- ● Ivalve yebhola ye-DBB (ibhloko ephindwe kabini kunye nevalve yebhola eyophayo)
- Iivalvu zebhola ze-DBB zibe ivelufa enye enezihlalo ezimbini ezichaseneyo.Le block kabini kunye nevalve ivelufa itywina ngokuchasene noxinzelelo oluvela kumacala omabini evalve.Le valve ayiboneleli ngokwahlula kabini okulungileyo xa icala elinye kuphela liphantsi koxinzelelo.
- Ivalve yebhola yeDBB inokuqwalaselwa njengevalve enezihlalo ezimbini zepiston enesiphumo esisodwa (SPE).
- ● Ivalve yebhola yeDIB (ukwahlulwa kabini kunye nevalve yebhola eyophayo)
- Ivalve yebhola ye-DIB yivalve enye enezihlalo eziphindwe kabini.Le valve yokwahlula kabini kunye neyokopha ibonelela ngetywina elongezelelweyo ngokuchasene noxinzelelo oluvela kwicala elinye kuphela.Olu phawu lweDIB lunokubonelelwa kwicala elinye okanye macala omabini.Ivalve ibonelela ngokwahlulwa kabini kuxinzelelo kuzo zozibini iziphelo zevalvu kodwa ayinako ukukhulula uxinzelelo lomzimba oludlula izihlalo.
- Umsebenzi weDIB unokubonelelwa kwicala elinye okanye omabini amacala.
- Ivalve ene-double piston effect (DPE) izihlalo zine-double isolation kunye ne-bleed (DIB-1) uyilo.Ivalve enesihlalo esinye se-SPE kunye nesinye isihlalo se-DPE yivalve yoyilo ye-DIB-2.Ivalve ye-DIB-2 iya kuba nesikhokelo sokufakela esikhethiweyo.
