Two -position three way directional control valve's mounting structure

The utility model relates to a two -position three way directional control valve's mounting structure, including switching -over valve body (5), valve plate (7), valve plate connecting rod (4) and cylinder body (1), valve plate (7) set up at switching -over valve body (5) inner chamber, the outside at switching -over valve body (5) is supported through bracing piece (8) in cylinder body (1), the abutting end of valve plate connecting rod (4) and piston rod (2) stretches out in switching -over valve body (5), is connected and realizes the switching of valve plate (7) with piston rod (2) of cylinder. At this external increase bracing piece of switching -over valve, the component form that makes piston rod and switching -over valve body becomes externally by built -in, avoids under the pistonrod is in coal gas A corrosive environment for a long time the life of improvement piston rod. 本实用新型涉及种二位三通换向阀的安装结构，包括换向阀体(5)、阀板(7)、阀板连杆(4)和气缸本体(1)，阀板(7)设置在换向阀体(5)内腔；气缸本体(1)通过支撑杆(8)支撑在换向阀体(5)的外部，所述阀板连杆(4)与活塞杆(2)的对接端从换向阀体(5)内
