✧ Kev piav qhia
BS 1868 yog ib tug qauv Askiv uas qhia txog cov kev cai rau cov hlau check valves lossis cov non-return valves nrog cov rooj zaum hlau rau kev siv hauv kev lag luam xws li roj av, petrochemical, thiab lwm yam kev lag luam. Cov qauv no suav nrog qhov loj me, qhov ntsuas siab-kub, cov ntaub ntawv, thiab cov kev cai kuaj rau swing check valves. Hauv cov ntsiab lus ntawm swing check valve tsim raws li BS 1868, nws yuav raug tsim los ua kom tau raws li cov qauv kev ntsuas thiab kev ua tau zoo uas tau teev tseg hauv tus qauv. Qhov no ua kom ntseeg tau tias lub valve tuaj yeem tiv thaiv kev ntws rov qab thiab ua tau raws li cov qauv kev nyab xeeb thiab zoo rau nws daim ntawv thov. Qee qhov tseem ceeb ntawm swing check valve tsim raws li BS 1868 cov qauv yuav suav nrog lub hau bolted, lub nplhaib rov ua dua tshiab, thiab lub disc swing-type. Cov valves no feem ntau siv rau hauv kev siv siab thiab kub siab uas tiv thaiv kev ntws rov qab yog qhov tseem ceeb. Yog tias koj muaj lus nug tshwj xeeb txog swing check valve tsim raws li BS 1868 cov qauv lossis xav tau cov ntsiab lus ntxiv txog nws cov lus qhia, cov ntaub ntawv, lossis cov kev cai kuaj, thov qhia rau kuv paub, thiab kuv yuav zoo siab los pab ntxiv.
✧ Cov yam ntxwv ntawm BS 1868 Viav Vias Kos Valve
1. Daim ntawv txuas lub cev valve thiab lub hau valve: Class150 ~ Class600 siv lub hau ntsaws valve; Class900 txog Class2500 siv lub hau kaw valve uas muaj lub siab nias rau nws tus kheej.
2. Qhov qhib thiab kaw qhov chaw (lub valve disc): lub valve disc yog tsim los ua hom viav vias, nrog lub zog txaus thiab kev tawv, thiab qhov chaw kaw ntawm lub valve disc tuaj yeem ua los ntawm cov khoom kub vuam lossis cov khoom tsis yog hlau raws li tus neeg siv xav tau.
3. Lub hau npog nruab nrab gasket daim ntawv ib txwm muaj: Class150 check valve siv stainless hlau graphite composite gasket; C|ass300 check valve nrog stainless hlau graphite qhov txhab gasket; Class600 check valve siv tau stainless hlau pob zeb 4. Ink winding gasket kuj siv tau hlau nplhaib gasket; Cov Class900 txog Class2500 check valves siv tus kheej-pressure sealing hlau nplhaib.
5. Daim ntawv ua haujlwm: Kos lub valve cia li qhib lossis kaw raws li qhov xwm txheej nruab nrab.
6. Kev tsim qauv rocker: Lub rocker muaj lub zog txaus, txaus kev ywj pheej los kaw lub valve disc, thiab muaj lub cuab yeej txwv tsis pub qhib qhov chaw siab dhau los kaw.
7. Tsim lub nplhaib nqa: Lub qhov ntsuas loj-caliber yog tsim los nrog lub nplhaib nqa thiab lub thav duab txhawb nqa, uas yooj yim rau kev nqa.
✧ Cov txiaj ntsig ntawm BS 1868 Swing Check Valve
Thaum lub sijhawm qhib thiab kaw ntawm lub forged steel globe valve, vim tias qhov kev sib txhuam ntawm lub disc thiab qhov chaw sealing ntawm lub cev valve me dua li ntawm lub rooj vag valve, nws yog hnav-resistant.
Qhov qhib lossis kaw ntawm lub valve qia luv luv, thiab nws muaj kev txiav tawm zoo heev, thiab vim tias qhov kev hloov pauv ntawm lub rooj zaum valve yog proportional rau qhov stroke ntawm lub valve disc, nws yog qhov tsim nyog heev rau kev hloov kho qhov ntws. Yog li ntawd, hom valve no yog qhov tsim nyog heev rau kev txiav lossis kev tswj hwm thiab kev tswj hwm.
