Ngokusetshenziswa okubanzi kwegesi yemvelo, igesi ye-petroleum ewuketshezi kanye namanye amandla ezimbonini nasezindaweni zomphakathi, indima ye-valve yokuvala izimo eziphuthumayo yomoya ophansi ekuvikelweni kokuphepha iya ngokuya ibaluleka. Ezimweni zokushisa eziphansi kakhulu, i-valve evamile yokuvala izimo eziphuthumayo ye-pneumatic ngokuvamile ayikwazi ukusebenza kahle, ngakho-ke ukuklama nokwakhiwaizinga lokushisa eliphansi lomoya we-pneumatic wokuvala i-valve yokuvala izimo eziphuthumayo ibhekene nezinselele eziningi. Lesi sihloko sizohlola lezi zinselele futhi sethule ezinye izixazululo zokuqinisekisa ukusebenza okuphephile ezindaweni ezishisayo.
Okokuqala, ukukhethwa kwezinto ezisezingeni eliphansi lokushisa imvelo
Endaweni yokushisa ephansi, izakhiwo ezibonakalayo zezinto ezibonakalayo zizoshintsha, njengamandla, ukuqina, ubulukhuni, njll., zizoncishiswa. Ngakho-ke, kubaluleke kakhulu ukukhetha izinto ezifanele indawo yokushisa ephansi. Ukuze uthole i-valve yokusika izimo eziphuthumayo zomoya ophansi, isidingo esikhulu sokucabangela ukukhethwa kwezinto ezifana nomzimba we-valve, ikhava yevalvu, isiqu se-valve kanye nezinto zokuvala.
Umzimba we-valve kanye nesembozo se-valve sidinga ukumelana nomphumela ohlangene wokucindezela okukhulu nokushisa okuphansi, ngakho-ke kuyadingeka ukukhetha izinto ezinamandla amakhulu, ukuqina okuphezulu nokumelana okuhle kokushisa okuphansi, njengensimbi ephansi ye-carbon, insimbi engagqwali nokunye. Isiqu se-valve sidinga ukuba namandla anele nokumelana nokugqoka, kuyilapho sicubungula ukunemba kokuxhumana kwayo nomzimba we-valve ukuze kuqinisekiswe ukusebenza kokuvala kwe-valve. Izinto zokubeka uphawu zidinga ukumelana nokushisa okuphansi okuhle kakhulu kanye nokuzinza kwamakhemikhali, njengerabha ye-fluorine, irabha ye-silicone nokunye.
2. Ubuchwepheshe bokubeka uphawu endaweni yokushisa ephansi
Endaweni yokushisa ephansi, ubulukhuni nokuqina kwempahla yokuvala kuzoncishiswa, okuholela ekwehleni kokusebenza kokuvala. Ngakho-ke, ekwakhiweni kwe-valve yokuvala izimo eziphuthumayo ze-pneumatic ezisezingeni eliphansi, ubuchwepheshe obukhethekile bokubeka uphawu buyadingeka ukuze kuqinisekiswe ukusebenza kokuvala.
Inqubo evamile yokuvala iwukusebenzisa ukwakheka kophawu olukabili, okungukuthi, indandatho yophawu lwensimbi ibekwe phakathi kwesihlalo nesiqu ukuze kwakhiwe uphawu olukabili. Lesi sakhiwo singavimbela ngokuphumelelayo ukuvuza kwe-medium futhi sithuthukise ukusebenza kokuvala kwe-valve. Ukwengeza, ukuze uvimbele ukuphuka kwesiqu se-valve endaweni ephansi yokushisa, umkhono wokuzivikela we-valve stem kanye nobunye ubuchwepheshe bungasetshenziswa.
Okwesithathu, inqubo yokukhiqiza ngaphansi kwemvelo ephansi yokushisa
Emazingeni okushisa aphansi, izinqubo ezivamile zokukhiqiza zingase zithinteke, ngakho-ke izinqubo ezikhethekile zokukhiqiza ziyadingeka. Isibonelo, ekukhiqizeni ama-valve wokuvala izimo eziphuthumayo ze-pneumatic ezisezingeni eliphansi, izinqubo zokwelashwa ze-cryogenic zingasetshenziswa ukuthuthukisa ukusebenza okuphansi kwezinga lokushisa kwezingxenye. Ngaphezu kwalokho, ngesikhathi sokucubungula izingxenye, amathuluzi akhethekile namathuluzi omshini ayadingeka ukuze kuqinisekiswe ukunemba kokucubungula kanye nekhwalithi ephezulu.
Ukuklama nokukhiqizwa kwe-valve yokuvala izimo eziphuthumayo ze-pneumatic eziphuthumayo kubhekene nezinselele eziningi, kodwa uma nje izinyathelo eziphumelelayo zithathwa ekukhethweni kwezinto ezibonakalayo, ubuchwepheshe bokubeka uphawu, inqubo yokukhiqiza, njll., ingaqinisekisa ukusebenza kwayo kokuphepha endaweni yokushisa ephansi. Esikhathini esizayo, ngokuthuthukiswa okuqhubekayo kwesayensi nobuchwepheshe, kukholakala ukuthi kuzoba nobuchwepheshe obusebenza kangcono, futhi ukusebenza kwe-valve yokusika izimo eziphuthumayo eziphuthumayo zomoya ophansi kuzoba phezulu nangaphezulu.
