Nhanganyaya Yekutarisa mavharuvhu

Cheki mavharuvhu mavharuvhu otomatiki anovhura nekuyerera kwemberi uye anovhara nereverse kuyerera.

Kudzvinyirirwa kwemvura inopfuura nepakati pegadziriro inovhura vharuvhu, nepo chero kudzoka kwekuyerera kunovhara valve. Kushanda chaiko kuchasiyana zvichienderana nerudzi rweCheck valve mechanism. Mhando dzakawanda dzeCheck mavharuvhu ndeyekuzunguza, kusimudza (piston uye bhora), shavishavi, mira uye tilting-dhisiki.

Mhando dzeCheck mavharuvhu

Swing Tarisa vharafu
A basic swing Check valve ine muviri wevharuvhu, bhoneti, uye dhisiki rakabatana kune hinge. Iyo dhisiki inozununguka kubva pavharuvhu-seat kubvumira kuyerera munzira yekumberi, uye inodzokera kuvharuvhu-seat kana kuyerera kwemvura kunomiswa, kudzivirira kuyerera.

Iyo dhisiki iri mumhando yekuzunguza Tarisa vharafu haina kutariswa sezvainovhura zvizere kana kuvhara. Kune akawanda dhisiki uye magadzirirwo ezvigaro aripo, kuitira kuti asangane nezvinodiwa zvezvikumbiro zvakasiyana. Ivhavha inobvumira kuyerera kuzere, kusina kuvharwa uye inovhara pakarepo sezvo kudzvinyirira kunoderera. Aya mavharuvhu akavharwa zvakazara kana kuyerera kwasvika zero, kuitira kudzivirira kudzoka shure. Turbulence uye kudonha kwekumanikidza muvharuvhu kwakadzikira.

Simudza Cheka vharafu
Dhizaini yechigaro chekusimudzira-Cheki vharafu yakafanana neGlobe valve. Iyo disc kazhinji iri muchimiro chepiston kana bhora.

Lift Check mavharuvhu anonyanya kukodzera basa repamusoro-soro apo velocity yekuyerera yakakwirira. Mukusimudza Tarisa mavharuvhu, dhisiki rinonyatsotungamirwa uye rinokwana zvakakwana mudhishibhoti. Lift Check mavharuvhu akakodzera kuisirwa mune yakachinjika kana yakatwasuka pombi-mitsetse inoyerera inokwira.

Kuyerera kusimudza Tarisa mavharuvhu anofanira kugara achipinda pazasi pechigaro. Sezvo kuyerera kunopinda, piston kana bhora rinosimudzwa mukati mevatungamiri kubva pachigaro nekumanikidzwa kwekuyerera kwepamusoro. Kana kuyerera kwamira kana kudzoka shure, piston kana bhora rinomanikidzwa pachigaro chevharuvhu nezvose zviri shure uye giravhiti.
