Lub lug hom npauj npaim valve muaj ob lub lugs los yog pob ntseg uas protrude los ntawm lub valve lub cev. Cov lugs no yog siv los tiv thaiv lub valve rau cov kav dej flanges siv bolts thiab ceev. Lub valve yog ntsia nruab nrab ntawm ob lub flanges, thiab cov lugs yog bolted rau ntawm flanges. Qhov kev tsim no tso cai rau lub valve tuaj yeem ntsia tau yooj yim thiab tshem tawm ntawm cov kav dej tsis muaj kev cuam tshuam cov kav dej uas nyob ib sab.
Lug hom npauj npaim li qub tau siv dav hauv ntau yam lag luam xws li kev kho dej, kev ua tshuaj, khoom noj thiab dej haus, tshuaj, thiab HVAC. Lawv nyiam rau lawv lub teeb yuag, compact tsim, tsis tshua muaj nqi, thiab yooj yim ntawm installation thiab txij nkawm.
Loj: DN 40-1200
2. Lub cev: cam khwb cia hlau / Ductile hlau / cam khwb cia hlau / Stainless hlau
3. Disc: Plated Ductile hlau / Stainless hlau / Aluminium Bronze / Carbon steel
4. Rooj: NBR / EPDM / PTFE / Neoprene / VITON / Natural roj hmab
NBR: Cov roj ua haujlwm zoo heev, hnav tsis kam, ua haujlwm kub zoo, muaj zog adhesion.
EPDM: (1) Tus nqi qis thiab kev ua haujlwm siab
(2) Kev laus zoo heev. Thaum siv ua ke nrog lwm cov roj hmab uas tsis muaj roj hmab xws li NR, SBR, BR, NBR, thiab CR, EPDM tuaj yeem ua raws li cov tshuaj tiv thaiv polymer los yog cov tshuaj tiv thaiv kev laus.
(3) Cov tshuaj tiv thaiv zoo heev, kua qaub, alkali, xab npum, thiab lwm yam; polar roj kuj.
(4) Dav daim ntawv thov kub ntau yam
PTFE: Zoo heev tshuaj stability, corrosion kuj, sealing, siab lubricity thiab tsis-stickiness thiab zoo kuj rau aging. Kub kub kuj, tsis kub tsis kam.
5. Muaj cov tes tuav, phau ntawv qhia iav thiab hluav taws xob / pneumatic / hydraulic actuators.
