Abantu abaninzi bayazibuza ukuba yintoni ivalve ezilawulayo. Enyanisweni, ivalve yokulawula ngokwayo ixhomekeke kuxinzelelo lwe-medium ejikelezayo kwivalve ngokwayo, kwaye ubushushu busebenza njengomthombo wamandla.
I-valve isebenza ngokuzenzekelayo ngaphandle kokunikezelwa kwamandla angaphandle kunye nesixhobo sesibini. Ngoko yintoni indlela yokusebenza yevalve yokulawula ezisebenza ngokwayo?
1. Indlela yokusebenza
Iivalvu ezizilawulayo ezisebenza ngokwazo zixhomekeke kwiigeyiji zoxinzelelo lwedijithali ezihamba phakathi kwendawo ngokwayo kuthungelwano. I-Celsius isetyenziswa njengevalve eshukumayo kwindawo yamandla ukuze isebenze ngokuzenzekelayo. Unikezelo lwamandla lwangaphandle kunye nezimbini ziyafuneka.
Isixhobo sesibini. Le valve yokulawula ngokwayo isebenzisa umthombo wesignali umva (i-digital pressure gauge, i-digriical pressure gauge, i-digriius) ekupheleni kwemveliso yevalve ukuhambisa umbutho wokusebenza ngetyhubhu yomthombo womqondiso.
I-disc yokuqhuba itshintsha ukuvulwa kwevalve ukulungelelanisa i-digital pressure gauge, izinga lokuhamba kunye ne-Celsius. Ivalve yokulawula inokwahlulwa ibe yimisebenzi ethe ngqo nengathanga ngqo.
Iintlobo ezimbini.
Umsebenzi othe ngqo wevalve yokulawula esebenza ngokuzimeleyo, eyaziwa ngokuba yi-spring-loaded type, ineenxalenye ezilastiki ezifana nentwasahlobo, i-bellows, i-bellows, iipakethi zobushushu, njl. kwisakhiwo sayo.
Umgaqo wokulinganisa phakathi kwamandla anamandla kunye nomthombo wesignali yempendulo kukuba ukuba i-digital pressure gauge eyeball_type elawula ivalve isetyenzisiwe, umthombo wesignali yengxelo yigeyiji yoxinzelelo lwedijithali ekuphumeni kwevalve.
Imibhobho yomthombo yaziswa kwintlangano yokusebenza. Ukuba ivalve yokulawula ukuhamba isetyenzisiwe, kukho ipleyiti ye-orifice (okanye esinye isixhobo esichasene ne-jamming) kwindawo yokuphuma yevalve ukususa uxinzelelo kuzo zozibini iziphelo zeplate ye-orifice.
Umthombo womqondiso wokwahluka ungeniswa kwintlangano yokusebenza. Ukuba uthungelwano oluzilawulayo luyi-Celsius degree, ukuphuma kwevalve kuya kuba ne-Celsius sensor (okanye igumbi lobushushu) ngokungeniswa kwe-Celsius sensor.
Ukwandiswa kwe-thermal esemgangathweni kunye nombutho wokusebenza kwe-contraction drive.
2.Amanqaku oFakelo
(1) indawo yoxinzelelo kufuneka ibekwe kwindawo efanelekileyo yevalve yokulawula uxinzelelo. Uxinzelelo kufuneka lube lukhulu kunamaxesha ama-2 ububanzi bombhobho phambi kwevalve, kwaye uxinzelelo emva kwevalve kufuneka lube lukhulu kunamaxesha ama-6 ububanzi bombhobho.
(2) Ngokobalo, idiamitha yevalve yebhola yemehlo inokuba ncinane kunelo lombhobho, ngelixa idiamitha yevalve yeglowubhu, ivalve yebhola esikiweyo, ivalve yokudlula kunye nesihluzo azinakuba ncinane kunoko. wombhobho.
Isishwankathelo esingentla solwazi malunga nendlela yokusebenza kwevalve yokulawula ukubona, ndiyakholwa ukuba ufunde ulwazi oluninzi emva kokuyibukela.
Ulwazi luluncedo kakhulu kubantu abaninzi, ngoko makhe silujonge.
