So the working efficiency is low . ( 3 ) from the structure of the logic valve , as the poppet valve is sealed by a line touching , the service life should be tested ( 3 )从逻辑阀的结构来看,由于逻辑阀芯是靠线接触来实现密封的,长期在快速冲压的条件下,其使用寿命尚待考验。
( 5 ) if the opening of the logic valve is limited , the fast transformation function of the logic valve will be improved , and the returning time of the piston will be reduced ( 5 )限制逻辑阀的开口量,可提高逻辑阀的快速换向性能,从而可缩短活塞的回程时间,提高系统的工作效率。
