Ivalve yesango lemela

Ivalve yesango lemela, ekwaziwa njengevalve yesango lemela, ivelufa eludaka lwemela. Amacandelo ayo okuvula kunye nokuvala ngamasango, ahambayo ahamba nge-perpendicular ukuya kwi-fluid direction direction, kwaye i-medium inqunyulwe ngesango le-knife-edge elingakwazi ukusika izinto zefiber. Isango linemigangatho emibini yokutywina. Imiphezulu emibini yokutywina yevalve yesango yendlela esetyenziswa kakhulu imile okwe wedge, kwaye i-engile yewedge iyahluka ngokweparameters zevalve, idla ngokuba ngama-50. . Ukuze wenze isango elinokuvelisa i-deformation encinci yokuphucula ubuchwephesha bayo kwaye yenze ukutenxa okubangelwa yi-angle yokutywinwa komhlaba kwinkqubo yokucubungula, olu hlobo lwesango lubizwa ngokuba yi-elastic gate. Enyanisweni, akukho gumbi kumzimba wevalvu. Isango liyanyuka kwaye liwele kwi-groove yesikhokelo esisecaleni, kwaye icinezelwe kwisihlalo nge-lug ephantsi. Ukuba ukutywina okuphakathi kuyafuneka, isihlalo sokutywina esimile okwe-O singasetyenziselwa ukufezekisa ukutywinwa kwe-bidirectional. I-valve yesango le-Knife inendawo encinci yokufakela, uxinzelelo oluphantsi lokusebenza, akulula ukuqokelela i-debris, ixabiso eliphantsi. Xa ivalve yesango lomese ivala, indawo yokutywina inokutywinwa kuphela ngoxinzelelo oluphakathi, oko kukuthi, indawo yokutywina yeplate yesango icinezelwe kwisihlalo kwelinye icala ukuze kuqinisekiswe indawo yokutywina, eyi-self-self. ukutywina. Uninzi lwee-valve zesango lomese zinyanzeliswa ukuba zitywinwe, oko kukuthi, xa i-valve ivala, i-plate yesango iphoqelelwe esihlalweni ngamandla angaphandle ukuze kuqinisekiswe indawo yokutywina. Iivalvu zolu hlobo ziya kufakwa ngokubanzi ngokuthe tye kwimibhobho. Iimpawu zeMveliso 1. Olu luhlu lweenkcukacha kunye neevalvu zifanelekile ukucocwa kwamanzi amdaka, ishishini lemichiza, ishishini lokucoca iphepha kunye noshishino lokuhlamba amalahle. Badlala indima yokusika kunye nokuvula kwimibhobho efana neebhola ezixhonyiweyo kunye nodaka oluphakathi kolwelo. 2. Iivalve zitywinwe ngamandla ahlangeneyo, angathembekanga kuphela, kodwa anokuphelisa iidiphozithi ukuhlangabezana neemfuno zokutywinwa. Umzimba wevalve unokwenziwa ngentsimbi yentsimbi, intsimbi yekhabhoni, insimbi engenasici kunye ne-polytetrafluoroethylene ukuhlangabezana neemfuno ezahlukeneyo zokuxhathisa ukubola kunye nokumelana nokunxiba. 3. Isakhiwo sifutshane ngobude kwaye silula ngobunzima. Ukufakela kunye nokugcinwa kulula kakhulu. 4. Ubushushu obusebenzayo: -10 ~ 120 5. Uxinzelelo lwegama (0.25MPa), 0.6MPa, 1.0MPa Imizobo yoyilo Ubungakanani obukhulu kunye nobunzima PN(MPa) DN(mm) LD D1 D2 D0 n-Th d H1 H2 重量 1.0 重量 1.0 1.6 50 48 165 125 99 180 4-M16 18 290 350 10 65 48 185 145 118 200 4-M16 18 310 375 11 80 51 28 201 201 430 13.5 100 51 220 180 156 240 8-M16 18 405 505 15.5 125 57 250 210 184 260 8-M16 18 450 575 23.5 150 57 285 240 212 280 8-M20 23 51007 62 62 62 0 8-M20/12-M20 23 610 810 43/43.5 250 70 395/405 350/355 319 340 12-M20/12-M24 23/27 765 1015 67.5/68 300 76 445/460 400/410 370 380 4/12-12M2-12-12 00.5/101 350 76 505/520 460/470 430 400 16-M20/16-M24 23/27 970 1320 126/127 400 89 565/580 515/525 480 450 70 12-12-4 176.2/177 450 89 615/640 565/585 530/548 530 20-M24/20-M27 27/30 1235 1685 289/290 500 114 670/715 620/650 582/302M 1286 1786 380 / 382 600 114 780/840 725/770 682/720 600 20-M27/20-M33 30/36 1486 2086 498.6/500 Isiqinisekiso sokufaneleka uMboniso Iivalvu zethu zifumene ingqwalasela eninzi eDubai.
