Ngaba iValve Yaphukile Ukuba Isondo Lesandla LiJika Ngokukhululekileyo?

Kwiimeko zokusetyenziswa kweevalvu zoshishino, i-handwheel yeyona nto isebenzayo, kwaye ukuguquguquka kwayo okujikelezayo kudla ngokungalunganga njengesalathisi kuphela sempilo yevalve. Nangona kunjalo, uphando ngengozi yokhuseleko ebangelwe kukuvuza kwangaphakathi kwevalve kwiplanti yekhemikhali eJiangsu ngo-2024 yabonisa ukuba ukusebenza kwevili lesandla sevalve yengozi akuzange kubonakale kubambekile kuyo yonke le nkqubo, kodwa umphezulu wokutywina wawunxibe ngokungaphindi uguquke. Eli tyala libangele umboniso woshishino kulwazi lwemveli ukuba "ukujikeleza kwevili lesandla=ivelufa eqhelekileyo". Eli nqaku lidibanisa imigaqo yoyilo lwevalvu, imigangatho yovavanyo lweshishini kunye namatyala okusilela okuqhelekileyo ukuhlalutya ngokucokisekileyo ulungelelwaniso phakathi kwemeko yokusebenza kwevili lesandla kunye neemeko zokwenyani zokusebenza kwesivalo.

2. Ukujikeleza kwamahhala ≠ ukungaphumeleli kwe-zero: iimeko ezintandathu ezifihliweyo zomonakalo
3. Inkqubo yokuchonga yobuchwephesha: imilinganiselo yovavanyo ngaphaya kokubonwa kwevili lesandla
4. Iinkcukacha zokugcinwa kweshishini: umthetho wegolide wolondolozo lothintelo

1. Umgaqo womatshini kunye nokubekwa komsebenzi wevalve handwheel
Njengeyunithi yofezekiso lwesiphelo setsheyini losasazo lwevalvu (Umfanekiso 1), imeko yokujikelezaivili lesandlaibonisa kuphela iimeko zokusebenza zendawo zenkqubo yokuhanjiswa kwe-valve stem. Ngokutsho kwe-GB / T 12224-2015 "IiMfuno eziPhambili kwiiValve zeNsimbi", i-torque esebenzayo ye-handwheel kufuneka ilawulwe ngaphakathi kuluhlu lokhuseleko lobunjineli lwe-30-350N · m. Lo mgangatho awuqinisekisi kuphela ukusebenziseka lula, kodwa ugwema umonakalo womatshini obangelwa ngamandla amaninzi.

Uhlalutyo lonxulumano lwamacandelo angundoqo:

Ikhonkco lothumelo:ivili lesandla → isiqu sevalve → isiqu sevalve → idiski yevalve (Umfanekiso 2)

Umda ongundoqo:Xa ukukhuhlana phakathi kwesikhondo sevalve kunye nokupakishwa kungaphezulu kwe-0.3MPa, isondo lesandla liya kuba nombono obalulekileyo wokuvaleka.

Yila indawo engaboniyo:Xa isixhobo somda webhokisi yebhokisi yeentshulube sisilela, ivili lesandla linokwenza idigri engama-360 ngaphandle kokuqhuba idiski yevalve

2. Ukujikeleza kwamahhala ≠ ukungaphumeleli kwe-zero: iimeko ezintandathu ezifihliweyo zomonakalo

Imeko 1: Ukutywina isibini singenzi nto

Kwivalve yesango, xa isithuba phakathi kwesikhondo sevalve yentloko yesikweri kunye nesango T-isithuba sendawo yokukhenkceza singaphezu kwe-0.5mm (Umfanekiso 3), ukujikeleza kwevili lesandla akunakuqhuba ukufuduswa kwesango. Izibalo ezisuka kumzi wokucokisa ngo-2023 zibonisa ukuba olu hlobo lokungaphumeleli "kwe-pseudo{5}}lokuguquguquka" lubalelwa kwi-17% yeziganeko zokusilela kwevalvu unyaka wonke.

Imeko yesi-2: Ukusilela kwenkqubo yokuthwala
Kwisakhiwo sothumelo lwegiya leentshulube, ukuba inaliti yokuzala yaphukile kodwa ikheji ayichithwanga, ivili lesandla lisakwazi ukugcina ngaphezulu kwe-60% yenkululeko ejikelezayo. Ngeli xesha, ukuhanjiswa kwangempela kwe-torque ye-valve stem yehle ukuya kwi-42% yexabiso loyilo.

Imeko yesi-3: Ukuqokelelana kwe-elastic deformation
Xa i-valve yebhola engaphezulu kwe-DN300 iphantsi koxinzelelo lombhobho ixesha elide, umzimba we-valve uya ku-0.02-0.15mm deformation yeplastiki. Olu tshintsho lwe-microscopic aluyi kuthintela ukusebenza kwe-handwheel, kodwa luya kubangela ukungahambi kakuhle kwe-0.03mm phakathi kwebhola kunye nesihlalo se-valve, kwaye umlinganiselo wokutywinwa wokutywinwa uya kuhla nge-76%.

Imeko yesi-4: Uphazamiseko oluphakathi lwecrystallization
Kwiivalvu zenkqubo yeekhemikhali, iikristale ezifana ne-boric acid kunye ne-ammonium sulfate ziqokelelana kwi-valve cavity ukuze zenze umaleko wokuzihlukanisa onzima (Umfanekiso 4). Ngaphantsi kwesi simo, ukuxhathisa ukujikeleza kwe-handwheel kwandisa kuphela nge-12%, kodwa ilahleko ye-valve ye-disc stroke yangempela ifikelela kwi-83%.

Imeko yesi-5: Ukusilela komqolo ophakathi{1}ovalekileyo ophindiweyo
Kuyilo lokutywina oluphindwe kabini lwevalve yebhola edityaniswe ngokupheleleyo, xa isihlalo sevalve esezantsi elayishwe ngaphambili silahlekelwa ngama-30%, iiparamitha zokusebenza kwevili lesandla zisengaphakathi koluhlu oluqhelekileyo, kodwa umsebenzi wokukhulula uxinzelelo lomqolo ophakathi uphulukene ngokupheleleyo.

Imeko yesi-6: Ukutenxa ngamawele edijithali
Xa inkqubo yengxelo yedijithali yevalvu ekrelekrele ekwaziyo ukusebenza isilela, ukutenxa phakathi "kwe-electronic smoothness" kunye "ne-jamming yomatshini" kunokwenzeka. Ngo-2024, isikhululo esithile sokufumana i-LNG kwiPhondo laseZhejiang sabangela ukuba inkqubo ye-ESD igwebe kakubi ngenxa yokusilela okunjalo.

Isishwankathelo
Ukujikeleza kwevili lesandla sisalathisi esingundoqo kuphela sovavanyo lwempilo yevalvu, kwaye "ukuguquguquka" kwayo kunokugubungela ngaphezulu kwe-70% yeengozi zokungaphumeleli ezinokubakho. Ngokukhutshwa koguqulelo olutsha lwe-API 598-2024 inkqubo yokuhlola, ishishini liyatshintsha ukusuka kumgwebo wobungqina ukuya kwidatha{5}}eqhutywa ngokuchanekileyo ukuxilongwa. Kucetyiswa ukuba amashishini aseke inkqubo yovavanyo enemigangatho emithathu ebandakanya uhlalutyo lwetorque, ukubhaqwa kokukhutshwa kwe-acoustic, kunye nokuziva okukrelekrele, kwaye kubhekiselele kumgangatho we-ISO 15848-1 wokuphucula ugcino lwedatha yokusebenza yokutywinwa. Kuphela kungokwaphula "inkolelo yevili lesandla" sinokufezekisa ukhuseleko lwendalo lolawulo lwevalvu kumjikelo wobomi bayo.

1: Ngaba amavili esandla sevalvu angasetyenziswa kwindawo ezirhabaxa?

A: Ewe, ii-handwheels zevalvu zinokuyilwa ukuba zimelane nemekobume erhabaxa ngokusebenzisa izinto ezikwaziyo ukumelana nokubola, i-UV kunye namaqondo obushushu aphezulu.

2: Ndilikhetha njani ivili levalvu ekunene kwisicelo sam?

A: Izinto ekufuneka ziqwalaselwe xa ukhetha ivili levalvu ibandakanya ubungakanani bevalve, indawo yokusebenza, itorque efunekayo kunye nesidingo sazo naziphi na iimpawu ezongezelelweyo (ezifana nezixhobo zokutshixa okanye izalathi zendawo).

3: Yintoni umsebenzi wevalve yesandla sokutshixa isixhobo?

A: Isixhobo sokutshixa isivalo ngesandla sisetyenziselwa ukuthintela ukusebenza okungagunyaziswanga okanye ngengozi kwevalve.

4: Ndiligcina njani ivili lesandla sevalvu yam?

A: Ukucocwa rhoqo kunye nokuthambisa i-valve handwheel kunokunceda ukuqinisekisa ukusebenza kakuhle. Ukongezelela, naziphi na iimpawu zokugqoka okanye umonakalo kufuneka zilungiswe ngokukhawuleza ukuze kuthintelwe imiba eyongezelelweyo.
