Kodi Valavu ya SDV ndi chiyani?

Ma Valuvu a SDVndi mtundu wa zida zodzitetezera zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale a petrochemical, mankhwala, chakudya ndi mafakitale ena komanso m'mapulatifomu amafuta akunja, dzina lonse ndivalavu yotseka, ndipo dzina la Chitchaina ndi Valve yodulidwa kapena Tsekani valavu. Izi ndi zomwe zafotokozedwa mwatsatanetsatane za valavu ya SDV:

Kapangidwe ndi kapangidwe ka ma Valves a SDV

Valavu ya SDV imapangidwa makamaka ndi magawo awiri: choyatsira ndi thupi la valavu. Choyatsira chimakhala ndi pisitoni, kasupe ndi dzanja, ndi gawo losinthira lokha. Ndi choyatsira mpweya choyatsira mpweya chofanana ndi chotsegulira mpweya, ndipo chili ndi valavu ya solenoid yotsegulira kapena kutseka njira ya mpweya, yomwe imagwiritsidwa ntchito kuwongolera kutsegula kapena kutseka kwa valavu.

Mfundo yogwirira ntchito ya valve ya SDV

Mfundo yogwiritsira ntchito valavu ya SDV imachokera pa choyatsira mpweya chopondereza mpweya. Pambuyo polandira malangizo a dongosolo la FSC kapena dongosolo lozimitsa mwadzidzidzi (ESDV), valavu imatsegulidwa kapena kutsekedwa yokha mwa kulamulira kuyatsidwa kwa gwero la mpweya wopanikizika kudzera mu valavu ya solenoid.

Ntchito ndi Kugwiritsa Ntchito Ma Valves a SDV

Valavu ya SDV imagwira ntchito ngati chitetezo chadzidzidzi mu dongosolo, ndipo nthawi zambiri imakhala pa payipi yotulukira ya chipangizocho. Zinthu zikavuta, imatha kudula mwachangu chitoliro cha mpweya kuti chilepheretse kuti cholumikiziracho chisapitirire kuyenda, motero kuonetsetsa kuti dongosololo lili lotetezeka.

Mavavu a SDV amagwiritsidwa ntchito kwambiri m'mapulatifomu amafuta am'madzi komanso m'makampani opanga mafuta am'madzi am'madzi. Pamapulatifomu amafuta am'madzi am'madzi, mavavu akuluakulu a SDV (monga kukula kwa valavu ≥16 mainchesi, gulu la mapaundi ≥900LB) nthawi zambiri amapezeka potulukira pa choyatsira mpira wa nkhumba kapena pakhomo la cholandirira mpira wa nkhumba, ndipo ndi zida zofunika kwambiri zotetezera panthawiyi.

Makhalidwe ndi ubwino

Valavu ya SDV ili ndi mawonekedwe otetezeka, odalirika komanso osavuta kusamalira actuator ya pneumatic, makamaka yoyenera madera oopsa.

Mavavu a SDV amatsegulidwa kwathunthu komanso kutsekedwa kwathunthu, kotero amadziwikanso kuti mavavu okhala ndi malo awiri. Kapangidwe kameneka kamathandiza mavavu a SDV kugwira ntchito bwino pamene kuyenda kwapakati kukufunika kudulidwa mwachangu komanso molondola.

Ku Summery

Mavavu a SDVndi chipangizo chofunikira kwambiri chotetezera chomwe chimagwira ntchito yofunika kwambiri m'mafakitale a petrochemical, mankhwala, chakudya ndi ena, komanso m'mapulatifomu amafuta akunyanja. Chimatsegula kapena kutseka chokha kudzera mu actuator ya pneumatic, chili ndi makhalidwe a chitetezo, kudalirika, kukonza kosavuta, ndipo chimatha kudula msanga kuyenda kwapakati pakagwa ngozi kuti chitsimikizire chitetezo cha dongosololi.
