Kaw-off valve rau dej thiab kua nruab nrab

Kaw-off valve yog ib tug valve uas nws lub hom phiaj yog ceev dawm taw yeeb nkab nyob rau hauv tag nrho los yog nyob rau hauv ib feem nyob rau hauv kev siv technology tshiab uas yuav tsum tau los yog nyob rau hauv cov ntaub ntawv ntawm thaum muaj xwm ceev. Nws lub ntsiab kom zoo dua yog ceev, raws li thaum lub caij nplooj ntoos hlav ntaus ntawv yog txhais sai li sai tau. Cocking caij nplooj ntoos hlav nqa los ntawm ib tug hluav taws xob los yog pneumatic Actuator.

Kaw-off valve: hom

Qhov no hom ntawm valve tej zaum yuav ua tau ib tug piston los yog diaphragm Actuator. Tsis tas li ntawd, lub kaw-off valve yuav mus rau ib qho ntawm cov hom: sib txuas lus, yuag, ib los yog ob lub rooj. Los ntawm txoj kev ntawm kaw no hom ntawm qhov cuab lub zog yog: caij nplooj ntoos hlav, pneumatically, los yog electromagnetically lockable load.

Scope

Kaw-off valve nrog ib tug propulsive lub cev siv los thauj cov sis plawv hniav-abrasive los yog kab mob kev kawm. Nyob rau hauv no ntaus ntawv tsis muaj teev aav. Steel nrog shutoff valve angular hydraulic piston muaj ib tug ob sab sib dho nyhuv, yog siv tau nyob rau ib kub siab ib puag ncig.

Tam sim no, qhov no hom ntawm qhov cuab lub zog muaj xws constructional nta nyob rau hauv uas cov kev tswj nruab nrab nyob rau ntawd officers feem ntau nquag siv. Xws li ib tug valve tshuab txais rau 1.5-10 vib nas this. Nws lub tog raj kheej thiab tsev nyob ib gasket, muab kauv mob, ua los ntawm steel, ib tug corrosion-resistant, nrog ib tug txheej ntawm asbestos. Yog hais tias peb los sib piv nrog rau lwm cov ib puag ncig, lub ceev ceev ntawm no hom ntawm valve yog heev siab heev, uas muaj txhawb mus rau lawv tsis muaj cov ntsaws ruaj ruaj. Tag nrho cov no yuav ho ua rau kom lawv muaj kev cia siab nyob rau hauv lub lag luam thiab ua rau kom efficiency.

Kaw-off valve nyob rau hauv dej: Tsis zoo li tshiab kev hloov kho ntawm cov laus

Tus tsim ntawm no hom ntawm qhov cuab lub zog ho hloov, ces koj yuav taug qab ob peb tseem ceeb sib txawv. Qhov tseem ceeb tshaj nta ntawm tus tshiab hloov yog:

• nce kuj mus paug;
• ib tug nce qib ntawm kev ncaj ncees;
• Kev ntseeg tau yog nce raws li ntau li ntau tau;
• teb ceev tshaj qub kev hloov kho;
• kab tej zaum yuav sib tshooj nyob rau hauv ob cov lus qhia: rau pem hauv ntej thiab rov qab.

Qhov no hom ntawm valve feem ntau siv rau hauv hwj chim tiam, sis plawv hniav thiab cov ntawv thiab cov zaub mov industries, raws li zoo li dej kev kho mob thiab nws cov kev npaj.

Yuav tsum muaj rau cov kaw-off fittings

Lub ntsiab yuav tsum tau nyob rau hauv cov ntaub ntawv no yog cov kev ceev ntawm cov lus teb. Raws li qhov no yog tiav los ntawm equipping cov valve caij nplooj ntoos hlav los yog ntau tshaj. Feem ntau nyob rau hauv xws designs, siv kauj springs los yog Belleville. Thaum uas siv cov hluav taws xob Actuator valve tsim presupposes lub hav zoov ntawm latches uas tuav lub caij nplooj ntoos hlav nyob rau hauv ib tug cocked mob, thiab lawv yog tswj los ntawm electromagnets. Tsis Siv Neeg kaw-off valve yog txhais instantly thiab cia li sai sai mus rau hauv standby hom yog tias tsim nyog.

Tag nrho cov ntau ntau yam ntawm no hom ntawm qhov cuab lub zog muaj peev xwm yuav ua los ntawm ntaub ntawv sib txawv: steel, yas, cam khwb cia hlau los yog stainless hlau.
