YDF-10 jonga ivalve core of excavator accessory cylinder

Ivalve yendlela enye ithetha ukuba ulwelo lunokuhamba kuphela kwindawo yokungena amanzi, kodwa indawo ephakathi kwindawo yokuphuma amanzi ayinakubuyela umva, eyaziwa ngokuba yivalve yendlela enye. Ivalve yokutshekisha ikwabizwa ngokuba ivelufa yokutshekisha okanye ivalve yokukhangela. Isetyenziswa kwisixokelelwano se-hydraulic ukuthintela ukuhamba okubuyela umva kokuhamba kweoyile, okanye isetyenziswe kwisistim yomoya ukuthintela ukujikeleza komoya ocinezelweyo. Kukho iintlobo ezimbini zeevalvu zokutshekisha: uhlobo oluthe ngqo kunye nohlobo lwe-angle ekunene. Ivalve yokujonga ngokuthe ngqo ifakwe kumbhobho ngoqhagamshelo olunentambo. Ivalve yendlela enye-engile ineendlela ezintathu: udibaniso oludityanisiweyo, uqhagamshelo lwepleyiti kunye noqhagamshelo lweflange.

Ivalve yokutshekisha ikwabizwa ngokuba ivelufa yokutshekisha okanye ivalve yokukhangela. Isetyenziswa kwisixokelelwano se-hydraulic ukuthintela ukuhamba okubuyela umva kokuhamba kweoyile, okanye isetyenziswe kwisistim yomoya ukuthintela ukujikeleza komoya ocinezelweyo.

Kukho iindidi ezimbini zeevalvu zokutshekisha: uhlobo oluthe tye kunye nohlobo lwe-angle ekunene. Ivalve yokujonga ngokuthe ngqo ifakwe kumbhobho ngoqhagamshelo olunentambo. Ivalve yendlela enye-engile ineendlela ezintathu: udibaniso oludityanisiweyo, uqhagamshelo lwepleyiti kunye noqhagamshelo lweflange. Ivalve yendlela enye yokulawula iHydraulic, ekwaziwa ngokuba ivelufa yokutshixa okanye ivalve yogcino loxinzelelo, iyafana nevalve yendlela enye ukunqanda ukubuya umva kweoyile. Nangona kunjalo, xa i-oyile ifuna ukuhamba ngokuphindaphindiweyo kwisiphaluka se-hydraulic, i-oyile yokulawula uxinzelelo ingasetyenziselwa ukuvula i-valve yendlela enye, ukwenzela ukuba i-oyile ihambe ngeendlela zombini. Ulawulo lwe-hydraulic ivalve yendlela enye ithatha i-conical valve core, ngoko inokusebenza kakuhle kokutywina. Xa i-oyile yesiphaluka kufuneka ivalwe, le valve ingasetyenziselwa njengendlela enye yokutshixa i-oyile yesiphaluka ukugcina uxinzelelo. Kukho iindlela ezimbini zokulawula ukuvuza kweoli: ukuvuza kwangaphakathi kunye nokuvuza kwangaphandle. Uhlobo lwangaphakathi lokuvuza lunokusetyenziswa kwisekethe yeoli ngaphandle koxinzelelo lwangasemva kwi-reverse outlet of oil flow; Ngaphandle koko, uhlobo lokuvuza luyafuneka ukunciphisa uxinzelelo lweoyile yokulawula.
