Umgaqo wokutywina kunye neempawu zesakhiwo sevalve yebhola edadayo

1. Umgaqo wokutywinwa weTaikeivalve yebhola edadayo

Indawo yokuvula neyokuvala yeTaike Floating Ball Valve yingqukuva enomngxuma ophumela kwidayamitha yombhobho embindini. Isihlalo sokutywina esenziwe nge-PTFE sibekwe kwisiphelo sokungena kunye nesiphelo sokuphuma, eziqulethwe kwivalve yentsimbi. Emzimbeni, xa umngxuma ophumela kwingqukuva udibana nomjelo wombhobho, ivalve ikwimo evulekileyo; xa umngxuma ophumela kwi-sphere i-perpendicular kumjelo wombhobho, ivalve ikwimeko evaliweyo. Ivalve ijika isuke ivuleke iye kuvalwe, okanye isuke ivale ivuleke, ibhola ijike i90°.

Xa ivalve yebhola ikwimeko evaliweyo, uxinzelelo oluphakathi kwisiphelo sokungena lusebenza ebholeni, luvelisa amandla okutyhala ibhola, ukuze ibhola icinezele ngokuqinileyo isihlalo sokutywina ekupheleni kokuphuma, kwaye kuveliswe uxinzelelo loqhagamshelwano. kumphezulu weconical wesihlalo sokutywina ukwenza indawo yoqhagamshelwano Amandla kwindawo nganye yeyunithi yendawo yoqhagamshelwano ibizwa ngokuba luxinzelelo oluthile lokusebenza q lwevalve yesitywina. Xa olu xinzelelo oluthile lukhulu kunoxinzelelo oluthile oluyimfuneko kwisitywina, i-valve ifumana isitywina esisebenzayo. Olu hlobo lwendlela yokutywina olungathembeli kumandla angaphandle, lutywinwe ngoxinzelelo oluphakathi, lubizwa ngokuba yi-medium self-sealing.

Kufuneka kucaciswe ukuba iivalvu zemveli ezifanaiivalvu zeglowubhu, iivalve zesango, umgca osembindiniiivalve butterfly, kunye neevalve zeplagi zixhomekeke kumandla angaphandle ukuba asebenze kwisitulo sevalve ukufumana isitywina esithembekileyo. Itywina elifunyenwe ngamandla angaphandle libizwa ngokuba litywina elinyanzelweyo. Amandla okutywinwa okunyanzeliswayo asetyenziswe ngaphandle ayinto engaqhelekanga kwaye ayiqinisekanga, engafanelekanga ekusebenziseni ixesha elide levalve. Umgaqo wokutywinwa we-valve yebhola ye-Taike ngamandla asebenza kwisihlalo sokutywina, esiveliswa ngoxinzelelo lwe-medium. La mandla azinzile, anokulawulwa, kwaye amiselwe ngoyilo.

2. Iimpawu zesakhiwo sevalve yebhola edadayo

(1) Ukuqinisekisa ukuba ingqukuva inokuvelisa amandla omthombo xa ingqukuva ikwimo evaliweyo, ingqukuva kufuneka ibe kufutshane nesihlalo sokutywina xa isivalo sidityaniswe kwangaphambili, kwaye uphazamiseko luyafuneka ukuvelisa isivalo sokutywina. Uxinzelelo lwe-pre-tightening ratio, olu xinzelelo lwangaphambi kokuqiniswa komlinganiselo I-0.1 amaxesha oxinzelelo lokusebenza kwaye ingabi ngaphantsi kwe-2MPa. Ukufumana lo mlinganiselo wokulayisha kwangaphambili uqinisekiswa ngokupheleleyo yimilinganiselo yejometri yoyilo. Ukuba ukuphakama okukhululekileyo emva kokudityaniswa kwe-sphere kunye ne-inlet kunye ne-outlet yokutywina izihlalo ngu-A; emva kokuba imizimba yevalve yasekhohlo kunye nekunene zidityanisiwe, umgodi wangaphakathi uqulethe i-sphere kwaye ububanzi besihlalo sokutywina ngu-B, ngoko ke uxinzelelo oluyimfuneko oluyimfuneko luyenziwa emva kokuhlanganisana. Ukuba inzuzo ngu-C, kufuneka yanelise: AB=C. Eli xabiso le-C kufuneka liqinisekiswe yimilinganiselo yejometri yamalungu acutshungulwayo. Kungacingelwa ukuba olu kuphazamiseka C kunzima ukumisela kunye nokuqinisekisa. Ubungakanani bexabiso lokuphazamiseka luchaza ngokuthe ngqo ukusebenza kokutywinwa kunye ne-torque yokusebenza yevalve.

(2) Kufuneka kucaciswe ngokukodwa ukuba ivalve yebhola edadayo yasekuqaleni kwakunzima ukuyilawula ngenxa yexabiso lokuphazamiseka ngexesha lokuhlanganisa, kwaye yayisoloko ihlengahlengiswa ngeegaskiti. Abavelisi abaninzi bade babhekisele kule gasket njenge-gasket yokulungelelanisa kwi-manual. Ngale ndlela, kukho i-gap ethile phakathi kweenqwelo-moya ezidibanisayo kunye nemizimba ye-valve encedisayo ngexesha lokuhlanganisa. Ubukho balo msantsa othile buya kubangela ukuba iibholithi zikhululeke ngenxa yokuguquguquka okuphakathi koxinzelelo kunye nokuguquguquka kobushushu obusebenzayo, kunye nomthwalo wombhobho wangaphandle, kwaye kubangele ukuba isivalo sibe ngaphandle. ukuvuza.

(3) Xa ivelufa ikwimo evaliweyo, amandla aphakathi kwisiphelo sokungena asebenza kwingqukuva, nto leyo eya kubangela ukushukuma okuncinci kumbindi wejiyometri wengqukuva, eya kuthi idibane ngokusondeleyo nesitulo sevalve kwindawo yengqukuva. ukuphela kokuphuma kunye nokwandisa uxinzelelo loqhagamshelwano kwibhendi yokutywina, ngaloo ndlela ufumana ukuthembeka. Itywina; kwaye amandla okuqinisa kwangaphambili kwesihlalo sevalve kwisiphelo sokungena ekudibaneni nebhola kuya kuncitshiswa, okuya kuchaphazela ukusebenza kokutywinwa kwesitulo sokutywina sokungena. Olu hlobo lwesakhiwo sevalve yebhola yivalve yebhola enokufuduswa kancinci kumbindi wejometri wengqukuva phantsi kweemeko zokusebenza, ebizwa ngokuba yivalve yebhola edadayo. Ivalve yebhola edadayo ivalwe ngesitulo sokutywina ekupheleni kokuphuma, kwaye akuqinisekanga ukuba isitulo sevalve kwindawo yokungena sinomsebenzi wokutywina.

(4) Ulwakhiwo lwevalvu yebhola edadayo yi-bi-direction, oko kukuthi, amacala amabini aphakathi angatywinwa.

(5) Isihlalo sokutywina apho ama-spheres adityanisiweyo senziwe ngezinto zepolymer. Xa iingqukuva zijikeleza, umbane ongatshintshiyo unokuveliswa. Ukuba akukho uyilo olukhethekileyo lwesakhiwo-i-anti-static uyilo, umbane ongatshintshiyo unokuqokelelwa kwiinkalo.

(6) Kwivalve eyenziwe zizihlalo ezibini zokutywina, umngxuma wevalvu unokuqokelelana okuphakathi. Enye i-medium inokunyusa ngokungaqhelekanga ngenxa yokutshintsha kweqondo lokushisa kunye neemeko zokusebenza, ezibangela umonakalo kumda woxinzelelo lwevalve. Ingqalelo kufuneka ihlawulwe.
