Description

一种直流变频压缩机组用气阀 技术领域
本发明涉及压缩机技术领域，具体为一种直流变频压缩机组用气阀。
背景技术
直流变频压缩机是随着直流无刷电动机的发展而迅速成熟起来的种新型机电一体化产品，出色的节能效果使它迅速占领了欧洲市场，直流变频空调其关键在于采用了无刷直流电机作为压缩机，其控制电路与交流变频控制器基本一样，我们把采用无刷直流电机作为压缩机的空调器称为“直流变频空调”，无刷直流电机与普通的交流电机或有刷直流电机的最大区别在于其转子是由稀土材料的永久磁钢构成，定子采用整距集中绕组，简单地说来，就是把普通直流电机由永久磁铁组成的定子变成转子，把普通直流电机需要换向器和电刷提供电源的线圈绕组转子变成定子，这样，就可以省掉普通直流电机所必须的电刷，而且其调速性能与普通的直流电动机相似，压缩机气阀是压缩机中用来控制气体及时吸入和排出气缸的重要部件，其性能直接影响压缩机的经济性与可靠性。
但是，现有的压缩机气阀阀片易断裂；因此，不满足现有的需求，对此我们提出了一种直流变频压缩机组用气阀。

优选的，所述气阀主体与气腔焊接连接。
与现有技术相比，本发明的有益效果是：
1、本发明通过固定环将气阀主体与阀座进行螺纹连接，连接方式简单，安装与拆卸方便快速；
2、本发明通过在进气腔和出气腔的两侧均设置有多个进气口与出气口，增加了单位时间内的进气量与出气量，工作效率更高，进气时气体先经第一主气孔的进气孔进入气腔的内部，再经第一进气口进入进气腔的内部，气体对连接板施加一个压力，连接板推动阀杆移动，当阀杆接触限位块时停止，此时被阀杆堵住的通孔打开，气体经通孔与第一出气口进入阀座的内部，最终经第二主气孔的进气孔完成压缩机的吸气，当压缩机排气时，气体经第二主气孔的排气孔进入，同理，气体最终经第二出气口进入气腔的内部，最终经第一主气孔的排气孔排出，通过阀杆代替阀片，相对于阀片拥有更高的机械强度，避免了长期工作下阀片的断裂，延长了整体的使用寿命。
