Ngimiphi imibandela yokukhetha ivalvu yevemvane kagesi kanye nevalvu yevemvane yomoya?

Iinzuzo nokusetjenziswa kwegeziamavalvu wevithamini

Igeziivalvu yevivanesisisetjenziswa esijayelekileko sokulawula ukugeleza kwepayipi, esineendlela ezinengi zokusetjenziswa begodu sifaka hlangana imikhakha eminengi, njengokulawula ukugeleza kwamanzi edamu ledamu lesikhungo samandla kagesi wamanzi, ukulawulwa kokugeleza kwamanzi webubulo efemini, njll., begodu okulandelako kuzokuthatha bona uzwisise ubujamo, ubuhle nokusetjenziswa kwevalvu kagesi.

1. Ukuvala okuhle

Phela, indima kagesiivalvu yevivaneisetjenziselwa ukulungisa ukugeleza kwe-fluid ngesikhathi, begodu iqalene namazinga womtjhiso aphezulu kanye nokugandeleleka okuphezulu lokha nayisebenzako, ngalokho nangabe ukuvala akukalungi, kuzokurholela ekuvuzeni kwe-fluid, begodu akukghonakali ukuqinisekisa ukulungiswa okunembileko kokugeleza. Ivalvu yevemvane kagesi inehlelo elikhethekileko lokuvala, njeke inokuvala okuhle hlangana namazinga womtjhiso aphasi khulu ukuya emazingeni womtjhiso aphezulu, okutjho bona, ukuvalwa kwevalvu yevemvane kagesi akuthintwa mazinga womtjhiso, begodu iswitjhi yevalvu yokulungisa igezi ilula khulu.

2. Akukho ukuvuza

Okuncomeka khulu kukuqina kweivalvu yevithamini kagesi, isivalo sobubanzi be-shaft sesiqu sevalvu samukela indandatho evaliweko khulu, indandatho yokuvala igandelelwe yi-graphite, indandatho yokuvala kanye nepuleti yevivane yevalvu yevemvane kagesi angeze yanamathela, ngalokho ukuvala kuhle khulu, ivalvu yevemvane kagesi yokuvikeleka emlilweni yinto ekhethwa bathengi abanengi.

3. Ukulungiswa okulula nokulawula

Igeziivalvu yevivaneyinto esetjenziselwa ukulawula ukugeleza kwe-fluid, ngaphezu kokuthutha nokulawula uketshezi, udaka nezinye izinto ezine-viscosity ethileko nazo zingathuthwa, begodu uketshezi olubuthelele epayipini luncani, begodu ukuvulwa nokuvalwa kwegezi kukhawuleza begodu kulula.

Kunemihlobo eminengiamavalvuisetjenziswa emabubulweni, kodwana kuthatha umzamo omkhulu ukuthenga ivalvu eyanelisako kwamambala, ivalvu ye-butterfly kagesi ineendlela ezinengi zokusetjenziswa, ukusebenza okuqinileko nokuvala okuhle khulu, begodu mhlobo wevalvu kagesi yebubulo esetjenziswa khulu.

Iinzuzo nokusetjenziswa kwe-pneumaticamavalvu wevithamini

Ivalvu ye-pneumatic butterfly yakhiwe yi-pneumatic actuator kanye ne-ivalvu yevivane. Ivalvu yevithamini ye-pneumaticyivalvu yomoya esebenzisa ipuleti eliyindilinga elijikelezako nesiqu sevalvu ukuvula nokuvala ukufezekisa isenzo sokukghonakalisa, esisetjenziswa khulu njengevalvu yokuvala, begodu ingaklanyelwa bona ibe nomsebenzi wokulungisa nofana ivalvu yokuhlukanisa nokulungisa, begodu ivalvu yevivane isetjenziswa khulu emapayipini amakhulu anamamitha aphasi naphakathi nendawo. Ukuhlukaniswa kwevalvu ye-pneumatic butterfly: i-stainless steel ye-pneumatic butterfly valve, i-hard seal pneumatic butterfly valve, i-soft seal pneumatic butterfly valve, i-carbon steel pneumaticivalvu yevivane. Iinzuzo ezikulu ze-pneumatic butterfly valve, isakhiwo esilula, ubukhulu obuncani, ubudisi obulula, iindleko eziphasi, i-pneumatic butterfly valve iqakatheke khulu, ifakwe emzileni omnyama ophakemeko, kulula ukuyisebenzisa ngokulawula i-valve ye-solenoid eneendlela ezinhlanu ezinendawo ezimbili, begodu ingalungisa nendlela yokugeleza.

Kunezinye izinto ezitlhoga ukuqalwa erherhweni lepuyere levalvu ye-pneumatic butterfly, ezifana: izinto angeze zaphuthunyiswa ngqo epuletini ye-valve ye-valve lokha nazifakwa ngaphakathi kwetroli ukusuka phezulu (amandla wokuthinteka la azokwenza bona i-valve ingakghoni ukuvala ngokuqinileko), begodu umfutho we-static wezinto akukafaneli udlule umfutho we-pneumatic umklamo wevalvu, njll.

Umehluko phakathi kwevalvu yokulawula nevalvu ejwayelekileko yesandla kukobana angeze yathathwa njengengcenye ehlukileko, kodwana kufanele ithathwe njengengcenye yohlelo lokulawula oluzenzakalelayo, imiraro eminengi ekusetjenzisweni kwevalvu yokulawula akusiwo umraro wokukhetha nokuhlela, kodwana ngombana ukuzwisisa komsebenzisi ngevalvu yokulawula akwanele, ivalvu yokulawula ayikaqedwa begodu ihlanganiswe nehlelo lokulawula. Inqobo nje nangabe sizwisisa ikhiye yomraro, sikhethe kuhle ivalvu, begodu silungise iphutha levalvu yokulawula esigabeni sokulungisa iphutha lehlelo, singakghona ukwehlisa khulu izinga lokubhalelwa begodu senze ihlelo lokulawula elizenzakalelayo lisebenze kuhle isikhathi eside.
