Iintlobo ezisibhozo zokuhlelwa kweemodeli zevalvu yesikhululo samandla

Isixhobo esinokulawula ukuhamba kolwelo kumbhobho ngokutshintsha icandelo lombhobho kuthiwa yivalve okanye ivalve part. Indima ephambili yevalve kumbhobho yile: ikhonkco edibeneyo okanye i-truncated medium; Thintela ukubuya kwemidiya; Lungisa uxinzelelo, ukuhamba kunye nezinye iiparameters ze-medium; Ukwahlula, ukuxuba, okanye ukusasaza imidiya; Ukuthintela uxinzelelo oluphakathi ludlula ixabiso elichaziweyo, ukwenzela ukugcina indlela okanye isitya, ukhuseleko lwezixhobo.
Kunye nophuhliso lwenzululwazi yale mihla kunye nobuchwepheshe, ivalve kushishino, ulwakhiwo, ezolimo, ukhuselo lwesizwe, uphando lwezenzululwazi kunye nobomi babantu kunye neminye imiba yosetyenziso oluxhaphakileyo, iye yaba ngumsebenzi womntu kwindawo nganye yeemveliso zoomatshini zendalo iphela eziyimfuneko. .
Iivalvu zisetyenziswa ngokubanzi kubunjineli bemibhobho. Kukho iintlobo ezininzi zeevalvu ngeenjongo ezahlukeneyo. Ngokukodwa kwiminyaka yakutshanje, izakhiwo ezitsha, izinto ezintsha kunye nokusetyenziswa okutsha kweevalvu ziye zaphuhliswa. Ukuze udibanise imigangatho yokuvelisa, kodwa kunye nokukhetha okuchanekileyo kunye nokuchongwa kwevalve, ukwenzela ukuba kube lula ukuveliswa, ukufakwa kunye nokutshintshwa, imilinganiselo yevalve isemgangathweni, ukulungelelanisa, ukuphuhliswa kolwalathiso lwe-serialization.
Ukuhlelwa kweevalvu:
Ivalve yeshishini yazalwa emva kokuveliswa kwenjini yomphunga, kwiminyaka engamashumi amabini okanye engamashumi amathathu edlulileyo, ngenxa yepetroleum, imichiza, isikhululo samandla, igolide, iinqanawa, amandla enyukliya, i-aerospace kunye neminye imiba yemfuno, yabeka phambili iimfuno eziphezulu ivalve, ukuze abantu uphando kunye nemveliso parameters eliphezulu ivelufa, ubushushu bayo yokusebenza ukusuka ubushushu yokuqala -269℃ ukuya 1200℃, nokuba phezulu 3430℃; Uxinzelelo olusebenzayo lwaluvela kwi-1.33 × 10-8Pa (1 × 10ˉ10mmHg) kwi-supervacuum ukuya kwi-1460MPa kwi-superpressure. Ubungakanani bevalve busuka kwi-1mm ukuya kwi-6000mm ukuya kuthi ga kwi-9750mm. Izixhobo zeValve ezivela kwintsimbi etyhidiweyo, intsimbi yekhabhoni, uphuhliso ukuya kwi-titanium kunye nentsimbi ye-titanium alloy, kunye nentsimbi enganyangekiyo kwi-corrosion, intsimbi ephantsi yobushushu kunye nevalve yensimbi ekwazi ukumelana nobushushu. Indlela yokuqhuba i-valve ukusuka kuphuhliso oluguquguqukayo ukuya kumbane, i-pneumatic, i-hydraulic, de kube yinkqubo yokulawula, umoya, ukulawulwa kude, njl njl.
Ngokwendima yevalve evulekileyo nevaliweyo, iindlela zokuhlela ivalve zininzi, apha ukwazisa ezi zilandelayo ziliqela.
