Iperi yokutywina yevalve yokutshekisha ihambele phambili kwaye inengqiqo.Umphezulu wokutywina we-valve clack kunye nesihlalo sevalve yenziwe ngentsimbi esekwe kwintsimbi okanye i-stellite cobalt esekwe kwisamente ye-carbide engaphezulu, enokumelana nokunxiba, ukumelana nobushushu obuphezulu, ukuxhathisa ukubola kunye nokuxhathisa umkrwelo.Ubomi obuhle kunye nobude benkonzo.

3. Ivalve yokutshekisha yenzelwe kwaye yenziwe ngokwemigangatho yesizwe ye-GB/T12235.

4. Ivalve yokutshekisha inokwamkela imigangatho eyahlukeneyo yemibhobho yeflange kunye neentlobo zokutywinwa kweflange ukuhlangabezana neemfuno ezahlukeneyo zobunjineli kunye neemfuno zomsebenzisi.

5. Isixhobo somzimba we-valve ye-valve yokutshekisha igqityiwe, kwaye i-gasket inokukhethwa ngokufanelekileyo ngokweemeko zangempela zokusebenza okanye iimfuno zomsebenzisi, kwaye inokufaneleka kwiingcinezelo ezahlukeneyo, ubushushu kunye neemeko zokusebenza eziphakathi.Ngokweemfuno zomsebenzisi, iivalve zokukhangela ezinezakhiwo ezahlukeneyo kunye noqhagamshelo zinokuyilwa kwaye zenziwe ukuba zisetyenziswe ngezixhobo ezahlukeneyo.

Ivalve yokukhangela ibhekisa kwivalve evula ngokuzenzekelayo kwaye ivale idiski ngokuxhomekeke ekuhambeni kwesixhobo ngokwayo, kwaye isetyenziselwa ukuthintela i-medium ukuba ingabuyeli ngasemva.Ikwabizwa ngokuba ivelufa yokutshekisha, ivalve yendlela enye, ivalve ebuyela umva, kunye nevalve yoxinzelelo lwangasemva.I-valve yokukhangela luhlobo lwe-valve oluzenzekelayo, umsebenzi walo oyintloko kukuthintela ukuhamba ngasemva kwe-medium, ukuthintela impompo kunye ne-motor drive ekubuyiseleni umva, kunye nokukhululwa kwe-container medium.Iivalvu zokutshekisha zingasetyenziselwa ukubonelela ngemibhobho yeenkqubo ezincedisayo apho uxinzelelo lunokwenyuka ngaphezu koxinzelelo lwenkqubo.Iivalvu zokujonga zinokwahlulwa ikakhulu zibe ziivalve zokujonga ujingi kunye neevalvu zokujonga ukuphakamisa.I-valve yokukhangela ifanelekile kwimibhobho yeemeko zokusebenza ezahlukeneyo kwi-petroleum, ikhemikhali, amayeza, isichumisi, kunye namashishini amandla ombane kunye noxinzelelo lwe-PN1.6 ~ 16.0MPa kunye nokushisa okusebenzayo kwe-29 ~ + 550 °.Indlela esebenzayo ngamanzi, i-oyile, umphunga, i-Acidic medium, njl.

Ivalve yokukhangela ivulwa ngokuzenzekelayo kwaye ivalwe ngamandla aveliswa kukuhamba komthombo ngokwawo kumbhobho, kwaye yeyevalve ezenzekelayo.I-valve yokutshekisha isetyenziswe kwinkqubo yokubhobhoza, kwaye umsebenzi wayo oyintloko kukuthintela i-medium ukuba ingabuyeli ngasemva, ukukhusela ipompo kunye ne-motor drive yayo ekubuyiseleni umva, kunye nokukhupha i-medium kwisitya.I-valve yokutshekisha ingasetyenziselwa ukubonelela ngemibhobho apho uxinzelelo lwenkqubo yokuncedisa inokunyuka ngaphezu koxinzelelo lwenkqubo ephambili.Umsebenzi wevalve yokukhangela kukuthintela okuphakathi kumbhobho ukuba ubuye umva.Iivalvu zokukhangela zezodidi lweevalvu ezizenzekelayo, ezivula okanye zivale ngokuzenzekelayo ngamandla omthombo ojikelezayo.Ivalve yokukhangela isetyenziselwa kuphela kwipayipi apho i-medium igeleza kwicala elinye ukukhusela i-medium ekubuyeni ukukhusela iingozi.Indawo esebenzayo yevalve yokutshekisha ngamanzi, ioli, umphunga, i-asidi medium, njl.
