Imininingwane yomgomo wokusebenza kwe-valve yebhola: ikuvumela ukuthi uqonde kabanzi nge-valve yebhola

I-valve yebhola iwuhlobo oluvamile lwe-valve, esetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni. Ukuqonda isimiso sokusebenza se-valve yebhola kusisiza ukuba siqonde kangcono izici zayo zokusebenza futhi sinikeze isiqondiso sezinhlelo zokusebenza ezingokoqobo. Lesi sihloko sizokunikeza incazelo eningiliziwe yesimiso sokusebenza se-valve yebhola, ukuze ube nokuqonda okujulile kwe-valve yebhola. Okokuqala, izici zesakhiwo se-valve yebhola I-valve yebhola ikakhulukazi yakhiwa umzimba we-valve, ibhola, isiqu se-valve, indandatho yokuvala uphawu nezinye izakhi. Phakathi kwabo, ibhola liyingxenye eyinhloko ye-valve yebhola, futhi isimo sayo sokusebenza sinquma ukuvulwa nokuvalwa kwe-valve. I-valve yebhola inesakhiwo esilula, ukusebenza okulula nokusebenza kahle kokuvala uphawu, okuyisizathu esiyinhloko sokusetshenziswa kwayo okubanzi. Okwesibili, isimiso sokusebenza se-valve yebhola 1. Qala inqubo (1) U-opharetha ushayela isiqu se-valve ukuze sijikeleze ngesiqu se-valve ukuze intambo esiqwini se-valve ixhumeke noma inqanyulwe entanjeni yebhola. (2) Lapho isiqu se-valve siphenduka, ibhola liphenduka ngokufanele. Lapho ibhola lizungeziswa endaweni okuxhunywe kuyo i-valve yokungena kanye neziteshi zokuphuma, okuphakathi kungageleza ngokukhululekile. (3) Lapho ibhola lizungeziswa liyiswe endaweni ehlukanisiwe ne-valve yokungena kanye nemigudu yokuphuma, i-medium ayikwazi ukugeleza ukuze ifinyelele ukuvala i-valve. 2. Vala inqubo Ngokuphambene nenqubo yokuvula, u-opharetha ushayela ukuzungezisa kwesiqu se-valve ngesiqu se-valve ukuze imicu esiqwini se-valve ixhumeke noma inqanyulwe emicu ye-sphere, futhi i-sphere ijikeleze ngokufanele. Lapho ibhola lizungezwa endaweni ehlukanisiwe ne-valve yokungena kanye neziteshi zokuphuma, i-medium ayikwazi ukugeleza ukuze ifinyelele ukuvalwa kwe-valve. Okwesithathu, ukusebenza kokuvalwa kwe-valve yebhola Ukusebenza kokuvala kwe-valve yebhola kuncike kakhulu esakhiweni sayo sokuvala kanye nempahla yokuvala. Isakhiwo se-Ball valve seal sihlukaniswe saba uphawu oluthambile kanye nensimbi yensimbi izinhlobo ezimbili. 1. Uphawu oluthambile: Indandatho yokuvala ye-valve yebhola elithambile ngokuvamile yenziwe ngerabha ye-fluorine, i-polytetrafluoroethylene nezinye izinto ezinokumelana nokugqwala okuhle nokumelana nokugqoka. Lapho i-valve ivaliwe, kwakhiwa isixhumi esibonakalayo sokuvala phakathi kwebhola nendandatho yokuvala ukuvimbela ukuvuza kwendawo. 2. I-Metal seal: Ukusebenza kokuvalwa kwe-valve yebhola evalwe ngensimbi ikakhulukazi kuncike ekulinganeni okuqinile phakathi kwebhola nesihlalo. Lapho i-valve ivaliwe, kwakheka isikhombimsebenzisi sokuvala esingenagebe phakathi kwebhola nesihlalo ukuze kuzuzwe uphawu. Ukusebenza kokuvala kwe-valve yebhola evalwe ngensimbi kungcono, kodwa ukumelana nokugqwala kubi kakhulu. Okwesine, ukusebenza kwe-valve yebhola Imodi yokusebenza ye-valve yebhola iyimanuwali, kagesi, i-pneumatic njalonjalo. Ukukhethwa kwemodi yokusebenza kufanele kusekelwe ezimweni zangempela zokusebenza kanye nezidingo zokusebenza. 1. Ukusebenza mathupha: Ukusebenza mathupha kwe-valve yebhola kudinga u-opharetha ukuthi ajikelezise ngokuqondile isiqu se-valve, ashayele ibhola ukuze ajikeleze, futhi abone ukuvulwa nokuvalwa kwe-valve. I-valve yebhola eqhutshwa ngesandla ifanele izikhathi lapho ukugeleza okuphakathi kukuncane futhi imvamisa yokusebenza iphansi. 2. Ukusebenza kukagesi: I-valve yebhola yokusebenza kagesi ishayela isiqu se-valve ukuthi ijikeleze ku-actuator kagesi ukuze ibone ukuzungezisa kwebhola, ukuze ibone ukuvuleka nokuvalwa kwevalvu. I-valve yebhola esebenza ngogesi ifanele isilawuli kude kanye nezinga eliphakeme lokuzenzakalelayo. 3. Ukusebenza kwe-pneumatic: i-pneumatic operation ball valve ngokusebenzisa i-actuator yomoya ukushayela ukujikeleza kwe-valve stem, ukufeza ukujikeleza kwebhola, ukuze kuzuzwe ukuvulwa nokuvalwa kwe-valve. I-pneumatic ball valve ifanele izinga lokushisa eliphakathi nendawo ephezulu, izikhathi eziyingozi kakhulu. V. Isiphetho Isimiso sokusebenza kanye nokusebenza kokuvala ama-valve ebhola kuwenza asetshenziswe kabanzi emikhakheni yezimboni. Ukuqonda isimiso sokusebenza se-valve yebhola kusisiza ukuba siqonde kangcono izici zayo zokusebenza futhi sinikeze isiqondiso sezinhlelo zokusebenza ezingokoqobo. Ngithemba ukuthi lesi sihloko singakusiza ukuthi uqonde i-valve yebhola ngokujulile.
