Kodi Valavu Yotseka Ndi Chiyani?

A valavu yotseka(SDV) ndi chipangizo chodzitetezera chokha chomwe chimapangidwa kuti chizimitse kuyenda kwa madzi mu payipi kapena dongosolo panthawi yadzidzidzi kapena zinthu zachilendo. Chimagwira ntchito ngati "mzere womaliza wodzitetezera" kuti chipewe ngozi, kuwonongeka kwa zida, kapena kuwonongeka kwa chilengedwe mwa kuletsa mwachangu kuyenda kwa madzi, mpweya, kapena mankhwala oopsa.

Ma SDV amagwiritsidwa ntchito kwambiri m'mafuta ndi gasi, mafakitale a mankhwala, kupanga magetsi, ndi mafakitale ena komwe kuyankha mwachangu kutuluka kwa madzi, kupanikizika kwambiri, kapena kulephera kwa makina ndikofunikira kwambiri. Kutha kwawo kugwira ntchito paokha—koyambitsidwa ndi masensa kapena makina owongolera—kumawapangitsa kukhala ofunikira kwambiri pa njira zamakono zotetezera mafakitale.

Kodi Valavu Yotseka Imagwira Ntchito Bwanji?

Ma valve otseka amagwira ntchito motsatira mfundo yosavuta koma yothandiza: **zindikirani, yatsani, ndikupatula**. Nayi njira yodziwira pang'onopang'ono momwe amagwirira ntchito:

1. Kuzindikira Matenda Osazolowereka

- Ma SDV amalumikizidwa ndi masensa kapena amalumikizidwa ku makina owongolera (monga, SCADA, DCS) omwe amawunika magawo monga kuthamanga, kutentha, kuchuluka kwa mpweya, kapena kutuluka kwa mpweya.

– Pamene malire okonzedweratu apitirira (monga kukwera kwa kuthamanga kwa mpweya kapena kuzindikira mpweya wa poizoni), dongosolo limatumiza chizindikiro ku valavu.

2. Kuyambitsa Valavu

– Akalandira chizindikiro, choyatsira magetsi cha valavu (choyatsira mpweya, choyatsira madzi, kapena chamagetsi) chimayamba kutseka nthawi yomweyo.

- Choyatsira magetsi chimasintha mphamvu (mpweya, madzi, kapena magetsi) kukhala kayendedwe ka makina kuti chisunthe chinthu chotseka valavu (monga mpira, chipata, kapena gulugufe).

3. Kupatula kwa Kuyenda

– Chotsekeracho chimatseka payipi, ndikuletsa kuyenda kwa madzi mkati mwa masekondi.

- Dongosolo likakhazikika, valavu ikhoza kubwezeretsedwanso pamanja kapena yokha kuti iyambenso kugwira ntchito mwachizolowezi.

Chofunika Chotengera: Ma valve otseka amaika patsogolo liwiro ndi kudalirika. Kapangidwe kawo kosalephera kulephera kamaonetsetsa kuti amatseka ngakhale magetsi atazimitsidwa kapena makina owongolera atalephera.

Zigawo Zazikulu za Valve Yotseka

Kumvetsetsa kapangidwe ka SDV kumathandiza kumvetsetsa bwino momwe imagwirira ntchito:

1. Thupi la Vavu

- Yopangidwa ndi zinthu zolimba monga chitsulo chosapanga dzimbiri kapena chitsulo cha kaboni kuti ipirire kupsinjika kwakukulu ndi zinthu zowononga.

- Imapezeka m'mapangidwe monga ma valve a mpira, ma valve a chipata, kapena ma valve a gulugufe, kutengera momwe imagwiritsidwira ntchito.

2. Chowunikira

- "Minofu" ya SDV, yomwe imayambitsa kuyenda kwa valve mwachangu.

–Zoyendetsa pneumaticgwiritsani ntchito mpweya wopanikizika,ma actuator a hydraulickudalira kuthamanga kwa madzi, ndipoma actuator amagetsikugwira ntchito pogwiritsa ntchito injini.

3. Chiyankhulo cha Dongosolo Lolamulira

- Imalumikiza valavu ku masensa, ma PLC, kapena makina otsekereza mwadzidzidzi (ESD) kuti iwunikire ndikuyambitsa nthawi yeniyeni.

4. Zosinthira Positioner ndi Limit

- Onetsetsani kuti ma valve ali pamalo oyenera ndipo perekani ndemanga pa momwe zinthu zilili potsegula/kutseka.

5. Kubwerezabwereza pamanja

- Amalola ogwiritsa ntchito kutseka kapena kutsegula valavu pamanja panthawi yokonza kapena kuyesa makina.

Ma Vavulovu Otseka a NSW: Monga wopanga ma valve odalirika otsekedwa, NSW imagwirizanitsa zipangizo zamakono ndi ma actuator osatetezeka kuti ipereke ma valve okhala ndi nthawi yoyankha ya

Ubwino Wogwiritsa Ntchito Ma Valves Otseka

Ma SDV amapereka maubwino angapo omwe amawonjezera chitetezo ndi kudalirika kwa magwiridwe antchito:

1. Kuyankha Mwachangu Mwadzidzidzi

– Ma SDV amatseka pasanathe masekondi ambiri, zomwe zimachepetsa chiopsezo cha kutayikira, kuphulika, kapena kuipitsidwa kwa chilengedwe.

2. Ntchito Yokha

- Kumachepetsa zolakwa za anthu mwa kuchotsa kudalira thandizo la manja panthawi yamavuto.

3. Kulimba M'malo Ovuta

- Zipangizo ndi zokutira zapamwamba kwambiri (monga epoxy, Inconel) zimathandizira kuti zikhale ndi moyo wautali m'malo otentha kwambiri kapena m'malo owonongeka.

4. Kutsatira Miyezo Yachitetezo

- Ma SDV amakwaniritsa miyezo yapadziko lonse lapansi monga API 6D, ISO 10434, ndi ziphaso za SIL 2/3, zofunika kwambiri m'mafakitale monga mafuta ndi gasi.

5. Kusamalira Kochepa

- Kapangidwe kolimba komanso zinthu zodziwonera zokha zimachepetsa nthawi yogwira ntchito komanso ndalama zomwe zimagwiritsidwa ntchito nthawi zonse.

Phunziro la Nkhani: Kampani yoyeretsera mafuta pogwiritsa ntchito ma valve otsekedwa ku NSW yanena kuti yachepetsa ndi 40% kutsekedwa kosakonzekera chifukwa cha kudalirika kwa ma valve pochotsa kutayikira kwa madzi panthawi ya kupanikizika.

Kugwiritsa Ntchito Ma Valves Otseka

Ma SDV ndi ofunikira m'mafakitale omwe chitetezo ndi kulondola sizingakambirane:

1. Mafuta ndi Gasi

- Zimateteza mapaipi ndi zida zoyendetsera ntchito ku mphamvu yochulukirapo, kutayikira, kapena ngozi za moto.

2. Kukonza Mankhwala

- Zimaletsa kutulutsa mwangozi mankhwala oopsa kapena oyaka.

3. Kupanga Mphamvu

- Amateteza ma boiler ndi makina a nthunzi ku kuwonongeka kwakukulu.

4. Mankhwala

- Kuonetsetsa kuti zinthu zodetsedwa sizili zoyera mwa kuzipatula panthawi yopanga.

5. Kukonza Madzi

- Imawongolera kuyenda kwa madzi m'makina opopera mphamvu kwambiri kuti zipangizo zisawonongeke.

N'chifukwa Chiyani Muyenera Kusankha NSW?Mongawopanga ma valve otsekedwa pamwamba, NSW imasintha mavavu kuti agwirizane ndi zinthu zinazake, kupanikizika, ndi kutentha. Mavavu awo amayesedwa maulendo opitilira 100,000, kuonetsetsa kuti amagwira ntchito bwino m'malo ovuta kwambiri.
