介<\/p>??1、用途
??在液壓系統(tǒng)中,工程上常將某一執(zhí)行機(jī)構(gòu)的進(jìn)回油路上相互控制,成對(duì)使用的兩個(gè)液控單向閥組合在同一個(gè)閥體內(nèi),稱之為雙向鎖。其可使執(zhí)行機(jī)構(gòu)在任意位置停止后,加以可靠的鎖定作用,從而避免在各種因素影響下可能發(fā)生的位移。
??2、執(zhí)行標(biāo)準(zhǔn)MT419——1995《液壓支架用閥》
??3、工作原理
   雙向鎖，包括閥體，開設(shè)在所述閥體內(nèi)的閥腔，和開設(shè)在閥體上與閥腔相通的進(jìn)、出液口；所述閥腔為水平貫穿閥體的通腔；在閥腔的中部密封滑動(dòng)設(shè)置有截面為“十”形的雙向頂桿；所述雙向頂桿的左、右頂桿分別延伸到設(shè)置在閥腔內(nèi)的左、右閥套內(nèi)，在所述左、右閥套內(nèi)分別設(shè)置有閥座；在閥腔左、右端口分別螺紋密封連接有開有凹腔的堵塞，在所述堵塞的凹腔內(nèi)分別設(shè)置有閥芯和回位彈簧；所述進(jìn)、出液口分為左進(jìn)、出液口和右進(jìn)、出液口；左、右進(jìn)液口分別通過各自的流道與對(duì)應(yīng)的左、右閥座側(cè)的閥腔相通；本實(shí)用新型優(yōu)點(diǎn)就在于板式閥體更便于閥體的拆裝；將閥芯、閥座分別設(shè)置在所述閥套、堵塞凹腔內(nèi)，板式的結(jié)構(gòu)更加簡(jiǎn)單緊湊。
??4、使用說明
??①本閥實(shí)用于31.5MPA的主管路及支管路的液壓系統(tǒng)中，工作介質(zhì)為含5％乳化液和95％中性水混合而成的乳化液，可在10℃--50℃溫度下正常工作，介質(zhì)需要保持清潔，無雜質(zhì)。采用0.125MM精度的過濾器及磁性過濾裝置過濾
??②本閥在井下如需要檢修時(shí)，應(yīng)整體更換，不可在井下拆檢，以防止贓物進(jìn)入閥腔內(nèi)
