Ndeapi marudzi akasiyana emavharuvhu ebhora?

Unoona mazwi akadai sekuti “full port,” “trunnion,” uye “floating ball” pama spec sheets. Aya mazwi ehunyanzvi anoita kuti zviome kuziva kana uri kuwana mashandiro akakodzera zvaunoda.

Kupfuura chimiro chemuviri, mavharuvhu ebhora anonyorwa zvichienderana nehukuru hwebhore rawo (chiteshi chakazara zvichienzaniswa nechiteshi chakajairwa) uye dhizaini yebhora remukati (rinoyangarara vs. trunnion).

Mhando dzeMavharuvhu Ebhora Pakutarisisa

Ndedzipi mhando dzakasiyana dzekubatanidza mavharuvhu ebhora?

Wawana vharuvhu yakakwana, asi ikozvino wava kuibatanidza. Kusarudza nzira isiriyo yekubatanidza kunogona kukonzera kuiswa kwakaoma, kudonha kwemvura nguva dzose, kana sisitimu yausingakwanise kugadzirisa pasina hacksaw.

Mhando dzekubatanidza dzinonyanya kuzivikanwa dzemavharuvhu ebhora imasoketi ekugadzirisa makemikari kuti pave nechisungo chePVC chinogara chiripo, mativi ane shinda ekubatanidza zvinhu zvakasiyana, magumo ane flange emapaipi makuru, uye kubatanidza kwechokwadi kweyuniyoni kuti pave nekushanda kwakanyanya.

Rudzi rwekubatanidza rwaunosarudza runotsanangura kuti vharuvhu inobatanidzwa sei nemapombi ako.Soketikana kuti "zvinotsvedza" zvinoshandiswa pakugadzira pombi yePVC, zvichigadzira chisungo chisingaperi, chisingadonhedze mvura uchishandisa simende inonyungudutsa.

Kuenzanisa Mhando dzeKubatanidza

Ndeapi marudzi akasiyana emavharuvhu eMOV?

Unoda kuita kuti system yako ishande otomatiki, asi "MOV" inonzwika semichina yakaoma yeindasitiri. Hauzive nezvesimba remagetsi, sarudzo dzekudzora, uye kana zvichinyatsoshanda pabasa rako.

MOV inomiriraValve Inoshanda Nemota, inova chero vharuvhu rinodzorwa neactuator. Mhando mbiri huru iactuator dzemagetsi, dzinoshandisa mota yemagetsi, uye actuator dzepneumatic, dzinoshandisa mweya wakamanikidzwa kushanda vharuvhu.

MOV haisi mhando yevharuvhu chaiyo; ivharuvhu yakajairika ine actuator yakaiswa pairi. Rudzi rweactuator ndirwo runonyanya kukosha.Ma actuator emagetsindiwo anonyanya kushandiswa pamavharuvhu ebhora ePVC mumasisitimu emvura. Anoshandisa mota diki kuvhura kana kuvhara vharuvhu uye anowanikwa mumavoltage akasiyana-siyana (senge 24V DC kana 220V AC) kuti aenderane nemagetsi auri kushandisa.
