1. Uyilo lweZitulo eziKhethekileyo

Ivalve yebhola edadayo yamkela uyilo lwesakhiwo seringi esiguquguqukayo. Xa uxinzelelo oluphakathi lusezantsi, indawo yoqhagamshelwano yomsesane wokutywina kunye nebhola incinci. ngoko ke umlinganiselo wokutywinwa ophezulu wenziwa kwindawo apho umsesane wokutywina kunye noqhagamshelwano lwebhola ukuqinisekisa ukutywinwa okuthembekileyo. Xa uxinzelelo oluphakathi luphezulu, indawo yoqhagamshelwano yetywina kunye nebhola iba nkulu kunye ne-elastic deformation yomsesane wokutywina, ngoko ke umsesane wokutywina unokunyamezela ukutyhala okuphakathi ngaphandle kokonakala.

2. Uyilo lweSakhiwo esingangenwa ngumlilo

Kwimeko yomlilo ngexesha lokusetyenziswa kwevalve, isihlalo sokuhlala esenziwe nge-PTFE okanye ezinye izinto ezingezizo zetsimbi ziya kuchithwa okanye zonakaliswe phantsi kobushushu obuphezulu kwaye kubangele ukuvuza okuphezulu. Umsesane wokutywina ongangeni umlilo usetwe phakathi kwebhola kunye nesihlalo ukuze emva kokuba isitulo sevalve sitshisiwe, indawo ephakathi iya kutyhala ibhola ngokukhawuleza ukuya kumsesane wokutywina wesinyithi osezantsi ukwenza intsimbi encedisayo kwisakhiwo sokutywina sesinyithi, esinokulawula ngokufanelekileyo ukuvuza kwevalve. Ukongeza, i-gasket yokutywina ye-flange ephakathi yenziwe ngentsimbi yenxeba yentsimbi, enokuqinisekisa ukutywinwa naphantsi kobushushu obuphezulu. Uyilo lwesakhiwo somlilo wevalve yebhola edadayo ihambelana neemfuno ze-API 607, spi 6FA, BS 6755 kunye neminye imigangatho.

3. Ukutywinwa okuthembekileyo kweSikhondo seValve

Isiqu sinikwa igxalaba emazantsi alo ukuze lingavuthelwa liphakathi naphantsi kweemeko ezinzima ezifana nokunyuka koxinzelelo olungaqhelekanga ngaphakathi kumngxuma wevalve, ukungaphumeleli kwepleyiti yedlala kunye njl njl. Ukongeza, ukuphepha ukuvuza emva kokuvuza. ukupakishwa kwesiqu kutshiswe xa kuthe kwatsha, i-thrust bearing ibekwe kwindawo apho igxalaba lesiqu kunye nokudibana nomzimba ukwenza isitulo sokutywina esibuyela umva. Amandla okutywinwa kwetywina elibuyela umva aya kwanda ngokonyuka koxinzelelo oluphakathi, ukuze kuqinisekiswe ukutywinwa kwesiqu esithembekileyo phantsi koxinzelelo olwahlukeneyo, ukuthintela ukuvuza kunye nokuphepha ukusasazeka kwengozi.

Isiqu samkela isakhiwo sokutywina sohlobo lwe-V. Ukupakishwa kohlobo lwe-V kunokutshintsha ngokufanelekileyo amandla ocinezelo kunye namandla aphakathi kwegland kumandla okutywinwa kwesiqu.

Ngokweemfuno zomsebenzisi, idisc spring elayishiweyo yokupakisha indlela yokucofa inokwamkelwa ukwenza ukutywinwa kokupakishwa kwesikhondo kuthembeke ngakumbi.

4. Ulwakhiwo lwe-Anti-static

Ivalve yebhola ibonelelwe ngesakhiwo esichasene ne-static kwaye yamkele isixhobo sokukhupha umbane ongatshintshiyo ukwenza ngokuthe ngqo ijelo engatshintshiyo phakathi kwebhola kunye nomzimba okanye yenze umjelo omileyo phakathi kwebhola kunye nomzimba ngesiqu, ukukhupha umbane ongatshintshiyo ovelisiweyo. ngenxa yokukhuhlana ngexesha lokuvulwa nokuvalwa kwebhola kunye nesitulo ngombhobho, ukuthintela umlilo okanye ugqabhuko-dubulo olunokuthi lubangelwe yintlantsi engatshintshiyo kunye nokuqinisekisa ukhuseleko lwenkqubo.

5. Isitshixo kunye noThintelo lokuSebenzisa kakubi

Ivalve yebhola yemanuwali inokutshixwa ngesitshixo xa ikwindawo evulekileyo epheleleyo okanye evaliweyo. Iqhekeza le-90 ° elivulekileyo nelivaliweyo elinomngxunya wokutshixa lenzelwe ukuphepha i-valve misoperation ebangelwa ngenxa yokusingatha ukusebenza ngabangasebenziyo, kwaye inokuthintela ukuvulwa okanye ukuvalwa kwevalve, okanye ezinye iingozi ezibangelwa kukungcangcazela kwemibhobho okanye izinto ezingalindelekanga. Isebenza kakhulu ngokukodwa kwizinto ezinokutsha. Isebenza kakhulu ngakumbi kwi-oyile etshayo kunye neqhumayo, imibhobho esebenzayo yekhemikhali kunye nezonyango okanye iityhubhu yasendle. Inxalenye esentlokweni yesikhondo efakwe ngesiphatho ithatha uyilo olucaba. Xa i-valve ivuliwe, isibambo sihambelana nombhobho, ukwenzela ukuba izibonakaliso zokuvula kunye nokuvala i-valve ziqinisekiswe ukuba akukho mpazamo.

Izixhobo ze-Newsway Valves

Umzimba wevalve ye-NSW kunye nemathiriyeli ye-trim inokubonelelwa ngohlobo lwe-Forged kunye nohlobo lokuCasa. Ecaleni kwezinto ezingenasici kunye ne-carbon steel, senza kwakhona iivalve kwizinto ezikhethekileyo ezifana ne-titanium, i-nickel alloys, i-HASTELLOY®*, i-INCOLOY®, i-MONEL®, i-Alloy 20, i-super-duplex, i-corrosion resistant alloys kunye ne-urea grade grade.
