Valavu ya chipata chotsetsereka ndi mtundu wa zida zazikulu zowongolera kuyenda kapena kunyamula kwa zinthu za ufa, zinthu za kristalo, zinthu za tinthu tating'onoting'ono ndi zinthu zafumbi. Ikhoza kuyikidwa pansi pa phulusa monga economizer, air preheater, dry fumbi remover ndi flue mu thermal power plant, ndipo ingagwiritsidwenso ntchito ndi magetsi odyetsa. Malinga ndi zipangizo zosiyanasiyana, kukana kutentha nakonso n'kosiyana. Kuthamanga kwa mkati kwa valavu ya chipata chotsetsereka: ≤ 1%; kuthamanga kwa kunja kwa valavu ya chipata chotsetsereka ndi zero.

Valavu ya chipata chotsetsereka ingagawidwe m'magulu awiri: magetsi, mpweya, magetsi ndi madzi. Valavu ya chipata chotsetsereka imagwiritsa ntchito mbale yapadera yoyezera, ndipo pamwamba pa valavu ya chipata chotsetsereka imakonzedwa ndi kutembenuza ndi kupukuta. Mpata wotsekera ndi wochepa ndipo magwiridwe antchito otsekera ndi abwino. Njira yolumikizira pakati pa valavu ya chipata chotsetsereka ndi payipi yamunda ikhoza kukhala kulumikizana kwa flange bolt kapena kulumikizana kwa butt ndi payipi.

1. Valavu yotsekeka ya chipata chotsetsereka imagwiritsa ntchito kapangidwe kake kotsekedwa bwino. Pambuyo poti diski yatsegulidwa, imayikidwa mchipinda chosungiramo zinthu chotsekedwa mbali inayo.

2. Valavu ya chipata chamagetsi imayendetsedwa ndi actuator yamagetsi, screw pair imazungulira kuti ipange kuyenda kwa axial, kenako guide drive screw sleeve imayendetsa plug-in disc kuti isunthe, ndipo plug-in plate imatulutsidwa kapena kukankhidwira mkati kuti amalize kutsegula kapena kutseka kwa plug-in plate, ndipo ntchitoyo ndi yokhazikika komanso yodalirika.

3. Valavu yolowera m'chitseko cha mpweya imayikidwa mu chipolopolo ndi silinda yotsegulira ndi yotseka kuti ikoke kapena kukankhira diski kuti itsegule kapena kutseka.

4. Unyolo wotsetsereka wa mpira umayikidwa mbali ziwiri za chipolopolo kuti uchepetse mbale yotsetsereka kuti iziyenda mu njanji yotsogolera. Ndi kapangidwe kabwino kwambiri, mbale yotsetsereka imayenda bwino komanso mosavuta, ndipo mphamvu yoyendetsera ndi yochepa.

5. Valavu ya chipata chotsetsereka imatha kuyendetsedwa patali kapena kuyendetsedwa ndi pulogalamu, yokhala ndi mawonekedwe owongolera kutali a DCS. Valavu ya chipata chotsetsereka yamagetsi ili ndi chipangizo chamagetsi cha Mechatronics, chomwe chingagwiritsidwe ntchito m'deralo komanso kutali, komanso chokhala ndi makina ogwiritsira ntchito mawilo amanja; valavu ya chipata chotsetsereka cha pneumatic ili ndi silinda ya mpweya ndi bokosi lowongolera, lomwe lingagwiritsidwe ntchito m'deralo komanso kutali.

Mukayitanitsa valavu ya chipata chotsetsereka, ndikofunikira kunena magawo a momwe ntchito ikuyendera motere:

1. Kukula, sing'anga yogwirira ntchito, njira yoyendera madzi apakati

2. Kuthamanga kwakukulu kwa ntchito (P) Pa, kutentha kwakukulu kwa ntchito (T) ℃

3. Kuwongolera kwa payipi (yopingasa / yoyima / yopendekera)

4. Liwiro lofunikira potsegula ndi kutseka

5. Malo oyika (mkati / panja)

6. Njira yogwirira ntchito: yamagetsi / pneumatic kapena yamanja

7. Njira yolumikizira ndi payipi (kulumikiza kwa kuwotcherera / flange)

1. Valavu ya chipata chamagetsi chotsetsereka

2. Valavu yolowera ya pneumatic slide

3. Valavu yolowera pa chipata chotsetsereka ndi manja
