Yintoni ivalve yebhola yentsimbi?
1. Umgaqo osebenzayo wevalve yebhola yensimbi engenasici
Ivalve yebhola yentsimbi luhlobo olutsha lwevalve esetyenziswa ngokubanzi. Umgaqo osebenzayo we-valve yensimbi engenasici kukujikeleza i-valve core ukwenza i-valve ingathinteli okanye ivalwe. Iivalve zebhola zensimbi ezingenasici zilula ukutshintsha, zincinci ngobukhulu, zingenziwa zibe ngamadamitha amakhulu, zinokutywinwa okuthembekileyo, isakhiwo esilula kunye nokugcinwa lula. Umphezulu wokutywina kunye nomphezulu we-spherical uhlala ukwimeko evaliweyo kwaye ayikhukulwa lula yi-medium. Zisetyenziswa kakhulu kumashishini ahlukeneyo.
I-valve yebhola yensimbi engenasici idinga kuphela ukujikeleza i-90 degrees kunye ne-torque encinci yokujikeleza ukuvala ngokuqinileyo. Umgodi womzimba wevalve olingana ngokupheleleyo ubonelela ngendlela yokuhamba ethe tye enokumelana okuncinci kumbindi. Into ephambili yevalve yebhola kukuba inesakhiwo esincinci kwaye kulula ukuyisebenzisa nokugcina. Iivalvu zebhola zensimbi engenastainless zingasetyenziselwa ukulawula ukuhamba kweentlobo ezahlukeneyo zolwelo olunjengomoya, amanzi, umphunga, imithombo yeendaba eyonakalisayo, udaka, ioyile, isinyithi esilulwelo kunye nemithombo yeendaba yeradioactive. Umzimba wevalve yebhola unokudityaniswa okanye udityaniswe.
2. Ukuhlelwa kweevalve zebhola zensimbi engenasici
Ukuhlelwa ngokwamandla:
Ivalve yebhola ye-pneumatic steel stainless steel, ivalve yebhola yombane yentsimbi, ivalve yebhola yentsimbi engenastainless.
Ukuhlelwa ngokwemathiriyeli:
I-valve yebhola ye-304 yensimbi engenasici, i-316L i-valve ye-stainless steel stainless, i-321 i-valve yebhola yensimbi engenasici, njl.
Zihlelwe ngokwesakhiwo:
(1) Ivalve yebhola edadayo - ibhola yevalve yebhola iyadada. Ngaphantsi kwesenzo soxinzelelo oluphakathi, ibhola inokuvelisa i-displacement ethile kwaye icinezele malunga nokutywinwa kwendawo yokuphuma ukuze kuqinisekiswe ukutywinwa kokuphela kokuphuma. Ivalve yebhola edadayo inesakhiwo esilula kunye nokusebenza kakuhle kokutywinwa, kodwa wonke umthwalo womsebenzi ophakathi kwibhola udluliselwa kwindandatho yokutywina yokuphuma. Ngoko ke, kuyimfuneko ukuqwalasela ukuba izinto zokutywina ziyakwazi ukumelana nomthwalo osebenzayo webhola lebhola. Esi sakhiwo sisetyenziswa ngokubanzi kwiivalvu zebhola eziphakathi kunye neziphantsi.
(2) Ivalve yebhola esisigxina: Ibhola yevalve yebhola izinzile kwaye ayishukumi emva kokuba icinezelwe. Ibhola esisigxina kunye neevalvu zebhola zonke zinezihlalo zeevalvu ezidadayo. Emva kokuba phantsi koxinzelelo oluphakathi, isihlalo sevalve siyahamba, sibangela ukuba umsesane wokutywina ucinezele ngokuqinileyo kwibhola ukuqinisekisa ukutywinwa. Iibherethi zivame ukufakwa kwi-shafts ephezulu kunye nesezantsi yebhola, kunye ne-torque encinci yokusebenza, kwaye ifanelekile kwi-high-pressure kunye ne-diameter-diameter valves. Ukuze kuncitshiswe i-torque yokusebenza ye-valve yebhola kunye nokwandisa ukuthembeka kwesitywina, i-valve yebhola etywinwe ngeoli iye yavela. Ioli ekhethekileyo yokuthambisa ijojowe phakathi kweendawo zokutywina ukuze zenze ifilimu yeoli, engagcini nje ukunyusa ukutywinwa, kodwa iyancipha i-torque yokusebenza kwaye ifanelekile. Uxinzelelo oluphezulu ivelufa yebhola edayamitha enkulu.
(3) Ivalve yebhola enwebekayo: Ibhola yevalve yebhola ilastiki. Umsesane wokutywina wesihlalo sebhola kunye nevalve zombini zenziwe ngezinto zetsimbi, kwaye uxinzelelo oluthile lokutywina lukhulu kakhulu. Uxinzelelo oluphakathi ngokwalo alukwazi ukuhlangabezana neemfuno zokutywinwa, kwaye kufuneka kusetyenziswe amandla angaphandle. Olu hlobo lwevalve lufanelekile kubushushu obuphezulu kunye noxinzelelo oluphezulu lwemidiya. I-elastic sphere ifumana ukunwebeka ngokuvula i-elastic groove kwisiphelo esisezantsi sodonga lwangaphakathi lwe-sphere. Xa uvala itshaneli, sebenzisa intloko emise okwentsimbi yesikhondo sevalve ukwandisa ibhola kwaye ucinezele isihlalo sevalve ukufezekisa itywina. Khulula intloko emise okwe wedge phambi kokuba ujike ibhola, kwaye ibhola iya kubuyela kwimo yayo yokuqala, ishiya isithuba esincinci phakathi kwebhola kunye nesihlalo sevalve, enokunciphisa ukukhuhlana kwindawo yokutywina kunye netorque yokusebenza.
Ukuhlelwa ngokwendawo yesitishi:
Iivalvu zebhola zinokwahlulwa zibe zivalve zebhola zentsimbi ethe tye, ezinendlela ezintathu zentsimbi engenastainless kunye ne-right-angle stainless steel valves ngokweendawo zazo. Phakathi kwazo, i-valve yebhola ye-stainless steel stainless stainless-shaped T-shaped three-shaped stainless steel stainless steel valve kunye ne-L-shaped three-shaped stainless steel stainless. Ivalve yebhola yentsimbi eneendlela ezintathu ezimilise okwe-T inokudibanisa imibhobho emithathu ye-orthogonal enye kwenye kwaye inqumle ijelo lesithathu ukuphambukisa kunye nokudibanisa ukuhamba. Ivalve yebhola yentsimbi enemilo emithathu enemilo engu-L inokudibanisa kuphela imibhobho emibini ye-orthogonal, kwaye ayikwazi ukugcina ukudityaniswa kombhobho wesithathu ngexesha elinye. Idlala kuphela indima yokusabalalisa.
Ihlelwa ngokokwakheka:
Ivalve yebhola yentsimbi engenaziqwenga ezibini, ivalve yentsimbi engenaziqwenga ezibini, ivalve yentsimbi engenasici.
