Kodi kudziwa udindo wa gulugufe valavu?kutsegula kapena kutseka

Mavavu agulugufe ndi zinthu zofunika kwambiri pakugwiritsa ntchito mafakitale osiyanasiyana.Amakhala ndi ntchito yotseka madzimadzi ndikuwongolera kutuluka.Choncho kudziwa mmene ma valve a gulugufe alili pogwira ntchito—kaya ali otsegula kapena otsekedwa—n’kofunika kwambiri kuti muwagwiritse ntchito ndi kuwasamalira bwino.

Kuwona ngati valavu yagulugufe ndi yotseguka kapena yotsekedwa imadalira makamaka pakuwona ndi zizindikiro.Pamene actuator si chogwirira, momwe mbale ya valve imasunthira mmwamba ndi pansi imakhala yosiyana ndi ma valve ena monga ma valve okwera tsinde ndi ma valve a globe (ma valve okwera tsinde amangofunika kuyang'ana kutalika kwa tsinde la valve kuti adziwe malo a mbale ya valve).Ma valve a butterfly ali ndi apadera Ma valve disc amatha kuzungulira 0-90 ° mu thupi la valve kuti asinthe kutuluka kwa madzi.

Umu ndi momwe mungadziwire malo a gulugufe mbale ya gulugufe valavu:

1. Visual inspection-toothed disc:

Mavavu agulugufe ang'onoang'ono, DN ≤ 250, amatha kukhala ndi zogwirira ndi ma disc a mano.Monga momwe dzinalo likusonyezera, disc ya mano nthawi zambiri imakhala ndi masikelo 10, yoyamba imakhala yotsekedwa, ndipo yomaliza imakhala yotseguka.
Tsegulani malo: Mukatsegula kwathunthu, diski ya valve imafanana ndi kayendetsedwe ka kayendetsedwe kake, kulola kuti njira yamadzimadzi ikhale yosasunthika.
Malo otsekedwa: Pamalo otsekedwa, diski ya valve imapanga kutsekeka kwamadzimadzi ndikuyimitsa kayendedwe ka madzi.

2. Chizindikiro cha malo:

Mavavu agulugufe ambiri ali ndi zizindikiro zakunja monga mivi kapena zolembera pamutu wa turbine.Zizindikirozi zimagwirizana ndi zizindikiro zomwe zimasonyeza malo a valve.

3. Chizindikiro cha ndemanga:

M'machitidwe apamwamba, zizindikiro zoyankha kuchokera ku masensa kapena zosinthika zimaphatikizidwa mu makina a valve, kupereka zenizeni zenizeni za momwe valve ilili.

4. Kuyang'anira patali:

Kukhazikitsa kwamakono m'mafakitale kutha kugwiritsa ntchito njira zowunikira patali zomwe zimalola ogwiritsa ntchito kuwona momwe ma valve agulugufe ali patali ndikuwongolera kuwongolera ndi kuyang'anira.
Kuonetsetsa kuti valavu ya gulugufe ili yoyenera ndikofunikira kuti musunge kukhulupirika, kupewa kutayikira komanso kukhathamiritsa magwiridwe antchito.Kuyendera ndi kukonza nthawi zonse kuyenera kuphatikizapo kutsimikizira momwe ma valvewa alili kuti achepetse chiopsezo ndi kusunga machitidwe.

Mwachidule, kudziwa ngati valavu ya gulugufe ndi yotseguka kapena yotsekedwa makamaka zimadalira zizindikiro zosiyanasiyana zowoneka ndi zamakono.Kumvetsetsa zidziwitso izi ndikofunikira pakuwongolera bwino kwa ma valve ndi ntchito zama mafakitale.
