Ivalufa yeButterfly yepneumatic, iValve yoLawulo oluzenzekelayo

Iimpawu zeMveliso

Izinto eziluncedo zevalve yebhabhathane yokutywina ethambileyo yomoya:

1. Isakhiwo silula, i-coefficient yokumelana nokuhamba incinci, iimpawu zokuhamba zivame ukuba zithe tye, kwaye akukho nkunkuma iya kugcinwa.
2. Uqhagamshelo phakathi kwepleyiti yebhabhathane kunye nesiqu sevalve yamkela i-pin-free structure, eyoyisa indawo yokuvuza yangaphakathi enokwenzeka.
3. Yahlulwe yaba yivalve yebhabhathane evalekileyo yokutywina ethambileyo kunye ne-pneumatic flange ethambileyo yokutywina ivalve yebhabhathane ukuhlangabezana nemibhobho eyahlukeneyo.
4. Izitywina zinokutshintshwa, kwaye ukusebenza kokutywinwa kunokwethenjelwa kwaye kunokufikelela kwi-zero ukuvuza kokutywinwa kwe-bidirectional.
5. Izinto zokutywina zichasene nokuguga, ukubola kunye nobomi benkonzo ende.

Inkcazo yepharamitha yeparamitha yebhabhathane yokutywina ethambileyo yomoya:

1.Idayimitha yeNominal: DN50～DN1200(mm).
2.Iklasi yoxinzelelo: PN1.0, 1.6, 2.5MPa.
3.Indlela yokudibanisa: Uqhagamshelo lwe-Wafer okanye i-flange.
Ifom ye-4.Spool: uhlobo lwediski.
Imowudi ye-5.Drive: Umthombo womoya wokuqhuba, umoya ocinezelweyo 5～7bar (ngevili lesandla).
6.Uluhlu lwesenzo: 0～90°.
7.Izinto zokutywina: zonke iintlobo zerabha, PTFE.
I-8.Isiganeko sokuSebenza: Imithombo eyahlukeneyo ye-corrosive, njl. (ubushushu obuqhelekileyo kunye noxinzelelo, ukushisa okuphantsi kunye nezihlandlo eziphantsi zoxinzelelo).
I-9.Okukhethwa kukho okufakelweyo: i-positioner, i-valve ye-solenoid, i-filter yokunciphisa uxinzelelo lomoya, i-valve yokugcina, i-switch switch, i-valve position transmitter, i-handwheel mechanism, njl.
I-10.Imodi yokulawula: tshintsha ulawulo lweendawo ezimbini, i-air-open, i-air-close, i-spring return, uhlobo lohlengahlengiso oluhlakaniphile (i-4-20mA uphawu lwe-analog).

Iimpawu zevalve yebhabhathane etywiniweyo eqinileyo yepneumatic:

1. Ukwamkela umgaqo-siseko we-eccentric kathathu, isihlalo sevalve kunye ne-disc plate ayinakho ukukhuhlana xa uvula kwaye uvala, okuphucula ubomi benkonzo.
2. Isakhiwo esiyingqayizivele, ukusebenza okuguquguqukayo, ukugcinwa kwabasebenzi, ukulungeleka, akuchatshazelwa nguxinzelelo oluphezulu okanye oluphantsi lwe-medium, kunye nokusebenza okuthembekileyo kokutywinwa.
3. Inokwahlulwa ibe yivalve yebhabhathane yomoya yotywino oluqinileyo kunye nevalve yepneumatic flange eqinileyo yokutywina ibhabhathane, ezilungele iindlela ezahlukeneyo zoqhagamshelo kwaye kulula ukuzifaka kumbhobho.
3. Ukutywinwa kuqulethwe ngamashiti ensimbi athambileyo kwaye aqinile, aneenzuzo ezimbini zokutywinwa kwentsimbi kunye nokutywinwa kwe-elastic, kwaye ineempawu ezibalaseleyo zokutywinwa kumaqondo aphantsi kunye aphezulu.
5. Ivalve yebhabhathane ixhotyiswe ngesixhobo sohlengahlengiso lokutywina.Ukuba ukusebenza kokutywinwa kuyancipha emva kokusetyenziswa kwexesha elide, ukusebenza kokutywinwa kwasekuqaleni kunokubuyiselwa ngokulungelelanisa i-disc yokutywina ikhonkco ukuya kwisihlalo sevalve, ephucula kakhulu ubomi benkonzo.

Iiparamitha zobuchwephesha zevalve yebhabhathane yokutywina elukhuni yomoya:

1.Idayimitha yesiqhelo: DN50～DN1200(mm)
2.Iklasi yoxinzelelo: PN1.0, 1.6, 2.5, 4.0MPa
3.Indlela yokudibanisa: uhlobo lwe-wafer, uxhumano lwe-flange
Ifom ye-4.Seal: isitywina esiqinileyo sesinyithi
Imowudi ye-5.Drive: umthombo womoya wokuqhuba, umoya ocinezelweyo 5 ~ 7bar (ngevili lesandla)
6.Uluhlu lwesenzo: 0～90°
I-7.Izinto eziphathekayo: i-carbon steel, i-stainless steel 304, i-stainless steel 316
8.Iimeko zokusebenza: amanzi, umphunga, i-oyile, i-acid corrosive, njl.
9.Uluhlu lobushushu: Intsimbi yeCarbon: -29℃～450℃ Intsimbi engatyiwa: -40℃～450℃
I-10.Imodi yokulawula: imodi yokutshintsha (i-switch-position control control, i-air-open, i-air-close), uhlobo lohlengahlengiso oluhlakaniphile (i-4-20mA uphawu lwe-analog), ukubuya kwentwasahlobo.
