具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何 限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如附图所示，本申请的实施例提供了一种气液分离器，包括：外筒10；输入管20，输入管20的一部分穿设在外筒10内，输入管20的入口位于外筒10的外部，输入管20的出口位于外筒10的内部；输出管30，输出管30的一部分穿设在外筒10内，输出管30的入口位于外筒10的内部，输出管30的出口位于外筒10的外部，输出管30的入口的设置位置高于输入管20的出口的设置位置；阻挡部40，设置在外筒10内，阻挡部40位于输出管30的入口和输入管20的出口之间，以将输出管30的入口和输入管20的出口间隔开。
应用本申请的技术方案，在气液分离器中设置有外筒10、输入管20、输出管30和阻挡部40，其中，输入管20的一部分穿设在外筒10内，输入管20的入口位于外筒10的外部，输入管20的出口位于外筒10的内部；输出管30的一部分穿设在外筒10内，输出管30的入口位于外筒10的内部，输出管30的出口位于外筒10的外部，输出管30的入口的设置位置高于输入管20的出口的设置位置；阻挡部40设置在外筒10内，阻挡部40位于输出管30的入口和输入管20的出口之间，以将输出管30的入口和输入管20的出口间隔开。这样可通过阻挡部40对输入管20的出口中输出的大颗粒的液态制冷剂或其他液体进行阻挡，避免了大颗粒的液体飞溅到输出管30的入口内，这样进入输出管30的只能是气体，因此该技术方案提高了气液分离器的气液分离效果，进而避免了液击损坏压缩机。
在本实施例中，阻挡部40具有避让孔41，避让孔41将阻挡部40上方的区域和阻挡部40下方的区域连通。这样从气液混合流体中分离出的气体可通过避让孔41从阻挡部40下方的区域进入到阻挡部40上方的区域，从而进入到输出管30内输出。
在本实施例中，阻挡部40为板状结构，阻挡部40的周缘与外筒10的内壁连接；在外筒10的径向方向上，避让孔41的面积小于阻挡部40的实体部分的面积。这样可通过阻挡部40的实体部分对大颗粒的液体进行阻挡，保证阻挡效果。
如图3所示，在本实施例中，输入管20的出口与避让孔41的边沿之间的距离H大于输入管20的外径L。通过上述设置，可保证阻挡部40对输入管20输出的流体的阻挡效果，避免大颗粒液体进入到输出管30内。
在本实施例中，输出管30的入口和输出管30的出口均位于阻挡部40的上方，阻挡部40具有限位孔42，输出管30穿过限位孔42，以通过限位孔42的内壁对输出管30进行限位。这样阻挡部40还能够起到对输出管30进行固定和限位的效果。
在本实施例中，输入管20包括相互连接的竖直段和水平段，其中，输入管20的入口位于竖直段的端部，输入管20的出口位于水平段的端部，输入管20的出口朝向外筒10的内壁。这样从输入管20输出的流体可以冲击到外筒10的内壁上，以将大颗粒液体打散雾化、或气化，提高气液分离效果。
在本实施例中，输出管30为U型结构，气液分离器还包括：过滤组件50，过滤组件50设置在输出管30的底部。这样可通过过滤组件50对流体进行过滤，以防止系统中的杂质封堵回油孔。
在本实施例中，气液分离器还包括：加强板60，设置在外筒10内，输出管30的底部穿过加强板60，以通过加强板60对输出管30进行固定。这样可通过加强板60对输出管30进行固定，提高气液分离器的可靠性。
在本实施例中，外筒10包括顺次连接的上盖、中筒和下盖，输入管20和输出管30均穿过上盖。这样便于各部件的装配并且提高结构强度。
可选地，气液分离器还包括底座，底座设置在外筒10的底部，通过设置底座，便于对气液分离器进行固定以及与其他装置连接。底座可以设置为多个，以提高可靠性。
本申请的另一实施例提供了一种压缩系统，压缩系统包括压缩机和上述提供的气液分离器，气液分离器的出口与压缩机的入口连通。在气液分离器中设置有外筒10、输入管20、输出管30和阻挡部40，其中，输入管20的一部分穿设在外筒10内，输入管20的入口位于外筒10的外部，输入管20的出口位于外筒10的内部；输出管30的一部分穿设在外筒10内，输出管30的入口位于外筒10的内部，输出管30的出口位于外筒10的外部，输出管30的入口的设置位置高于输入管20的出口的设置位置；阻挡部40设置在外筒10内，阻挡部40位于输出管30的入口和输入管20的出口之间，以将输出管30的入口和输入管20的出口间隔开。这样可通过阻挡部40对输入管20的出口中输出的大颗粒的液态制冷剂或其他液体进行阻挡，避免了大颗粒的液体飞溅到输出管30的入口内，这样进入输出管30的只能是气体，因此该技术方案提高了气液分离器的气液分离效果，进而避免了液击损坏压缩机。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
