Pneumatic Butterfly Valve, Automatic Control Valve

Makhalidwe Azinthu

Ubwino wa valavu yagulugufe yofewa ya pneumatic:

1. Mapangidwewa ndi ophweka, koyenera yotsutsana ndi kutuluka ndi yaying'ono, mawonekedwe othamanga amakhala owongoka, ndipo palibe zinyalala zomwe zidzasungidwa.
2. Kulumikizana pakati pa mbale yagulugufe ndi tsinde la valve kumatenga kachipangizo kopanda pini, komwe kumathetsa kutayikira kwamkati komwe kungatheke.
3. Agawanika kukhala pneumatic wafer mtundu ofewa kusindikiza gulugufe valavu ndi pneumatic flange zofewa kusindikiza gulugufe valavu kukumana mapaipi osiyana.
4. Zisindikizo zimatha kusinthidwa, ndipo ntchito yosindikiza ndiyodalirika ndipo imatha kukwaniritsa zero kutayikira kwa kusindikiza kwa bidirectional.
5. Zida zosindikizira zimagonjetsedwa ndi ukalamba, dzimbiri komanso moyo wautali wautumiki.

Kufotokozera za parameter ya gulugufe wofewa wa pneumatic:

1.Dyating'ono mwadzina: DN50～DN1200(mm).
2.Pressure class: PN1.0, 1.6, 2.5MPa.
3.Kulumikizana njira: Wafer kapena flange kulumikizana.
4.Spool mawonekedwe: chimbale mtundu.
5.Drive mode: Air source drive, wothinikizidwa mpweya 5～7bar (ndi gudumu lamanja).
6.Zochita zosiyanasiyana: 0～90°.
7.Sealing zakuthupi: mitundu yonse ya labala, PTFE.
8.Ntchito yogwira ntchito: Zofalitsa zosiyanasiyana zowononga, etc. (kutentha kwanthawi zonse ndi kupanikizika, kutentha kochepa komanso nthawi yochepa).
9.Accessory options: positioner, solenoid valve, air filter pressure reducer, retainer valve, switch switch, valve position transmitter, handwheel mechanism, etc.
10.Control mode: kusintha mawonekedwe awiri, kutseguka kwa mpweya, kutseka kwa mpweya, kubwerera kwa masika, mtundu wosinthika wanzeru (4-20mA chizindikiro cha analogi).

Pneumatic hard sealing valve performance performance:

1. Kutengera kapangidwe ka katatu ka eccentric mfundo, mpando wa valve ndi mbale ya disc imakhala yopanda phokoso potsegula ndi kutseka, zomwe zimapangitsa moyo wautumiki.
2. Mapangidwe apadera, ntchito yosinthika, yopulumutsa ntchito, yabwino, yosakhudzidwa ndi kupanikizika kwakukulu kapena kochepa kwapakati, ndi ntchito yodalirika yosindikiza.
3. Ikhoza kugawidwa mu pneumatic wafer mtundu molimbika kusindikiza gulugufe valavu ndi pneumatic flange molimba kusindikiza gulugufe valavu, amene ali oyenera njira zosiyanasiyana kugwirizana ndi zosavuta kukhazikitsa mu payipi.
3. Kusindikiza kumapangidwa ndi mapepala a laminated ofewa ndi olimba, omwe ali ndi ubwino wapawiri wa kusindikiza zitsulo ndi kusindikiza zotanuka, ndipo ali ndi makhalidwe abwino kwambiri osindikizira pa kutentha kochepa komanso kotentha.
5. Vavu yagulugufe ili ndi chipangizo chosindikizira chosindikizira.Ngati ntchito yosindikiza ikucheperachepera pambuyo pa kugwiritsidwa ntchito kwa nthawi yayitali, ntchito yosindikiza yoyambirira ikhoza kubwezeretsedwanso mwa kusintha mphete yosindikizira ya disc kuti ifike ku mpando wa valve, zomwe zimathandizira kwambiri moyo wautumiki.

Magawo aukadaulo a valavu yagulugufe yolimba ya pneumatic:

1.Dyace wadzina: DN50～DN1200(mm)
2.Pressure class: PN1.0, 1.6, 2.5, 4.0MPa
3. Njira yolumikizira: mtundu wawafer, kulumikizana kwa flange
4.Seal mawonekedwe: chitsulo cholimba chisindikizo
5.Drive mode: mpweya gwero galimoto, wothinikizidwa mpweya 5 ~ 7bar (ndi dzanja gudumu)
6.Zochita zosiyanasiyana: 0～90°
7. Thupi lakuthupi: chitsulo cha carbon, chitsulo chosapanga dzimbiri 304, chitsulo chosapanga dzimbiri 316
8.Makhalidwe ogwirira ntchito: madzi, nthunzi, mafuta, acid corrosive, etc. (angagwiritsidwe ntchito pa kuthamanga kwambiri ndi ntchito kutentha kwambiri)
9.Kutentha osiyanasiyana: Carbon zitsulo: -29℃～450℃ Stainless Chitsulo: -40℃～450℃
10.Control mode: kusintha mode (awiri-position switch control, air-open, air-close), wanzeru kusintha mtundu (4-20mA analogi chizindikiro), masika kubwerera.
