Valv idwolik valv valv threaded katouch valv lf12 koule kontwòl valv LNV-12

Valv la katouch Threaded se yon Rotary monte katouch valv, ki se vise nan twou a Threaded nan blòk la lwil oliv pa ploge nan ak fil pwòp li yo (jan yo montre) pou ke konpozisyon an nan estrikti nan sistèm idwolik se pi plis kontra enfòmèl ant, volim li yo se pi piti, pi lejè pwa, fil vis sou sele a yo fòme yon sele sere ka asire ke sistèm nan idwolik pa gen fwit. Se poutèt sa, paske nan zero fwit li yo, segondè inite volim dansite, ti espas, fasil demont ak ranplase, pri-efikas, ka dirèkteman konekte ak actionneur a (tankou idwolik silenn, motè) enpòte ak ekspòtasyon pati, fasil enstalasyon ak debogaj ak lòt avantaj, pa domestik la ak etranje atansyon endistri idwolik. Figi 2 montre aplikasyon an tipik nan Vickers vis insert valv nan konkrè ponpe aparèy nan machin konstriksyon sany. Se prensip k ap travay li yo montre nan fig frans. 1.B. When the piston is about to reach the end point and cross port A, due to the damping effect of the damping hole, a pressure difference is formed at both ends of the cartridge valve spool, so that port C provides reversing control oil, and then through the damping of the oil drain valve, the pressure is built to drive the pilot small hydraulic valve of the swing four-way valve, resulting in the reversal of the swing valve and complete konkrè ponpe mwatye yon sik nan commutation idwolik.
 

Since SANY concrete pumping engineering machinery adopts a single loop hydraulic system (that is, the concrete distribution valve cylinder and the pumping cylinder are in the same loop), the key of this system is how to realize the automatic sequential action of the concrete distribution valve cylinder and the pumping master cylinder, so the two main cylinders of the pumping device of Sany drag pump and pump truck are equipped with threaded Valv katouch (Figi 2.). Bay siyal kontwòl presyon, se konsa ke operasyon an konkrè ponpe nan pwosesis la nan egzat ak alè, se sa ki, sistèm nan idwolik tèt li ranpli silenn lan mèt ponp ak silenn nan valv distribisyon nan commutation altènatif la nan sik la konplè idwolik commutation, fèt san pwoblèm nan aspirasyon ak bag operasyon manje.
