结合图2和图3所示，根据本申请的实施例，提供了一种压缩机。
具体地，如图2所示，压缩机包括气缸座10、气缸盖20、定位组件和阀板组件30。气缸盖20通过连接件与气缸座10相连接。定位组件包括第一定位件和与第一定位件相配合的第二定位件，第一定位件和第二定位件中的一个设置于气缸座10上，第一定位件和第二定位件中的另一个设置于气缸盖20上。阀板组件30可通过定位组件预装至气缸座10上并位于气缸盖20与气缸座10之间。
在本实施例中，通过设置定位组件以将阀板组件预装在气缸座和气缸盖之间，这样设置能够方便实现阀板组件的安装和拆卸，有效地降低了阀板组件的安装难度，提高了压缩机的装配效率。
其中，第一定位件为定位柱41，定位柱41设置于气缸盖20上，第二定位件为定位孔42，定位孔42开设于气缸座10上。这样设置使得定位组件的结构简单，装配起来可靠。
为了使得定位柱41能够起到防止阀板组件中的各个部件装反，可以在定位柱41的表面设置有直面411。其中，定位柱41的横截面可以是正方形、矩形、椭圆形或三角形。当然，定位柱41的直径也可以设置呈渐变的方式。
具体地，阀板组件30包括阀板31。阀板31的中部设置有阀板排气孔311，位于阀板排气孔311的一侧设置有供定位组件穿过的阀板限位孔312。这样设置能够方便阀板31的安装。位于阀板限位孔312的相对侧设置有阀板吸气口313，位于阀板吸气口313的一侧设置有阀板排气通孔314。采用该结构的阀板结构能够避免在阀板上开设凹槽安装升程限位器，有效地降低了阀板的加工难度。
进一步地，阀板31的至少部分外边缘的型线设置成弧线。这样设置能够避免将阀板设置成现有技术中的方形结构，采用本实施的阀板结构，能够有效地减小阀板的加工材料，从而有效地减小了压缩机的生产成本。其中，弧线的长度为C，弧线的曲率半径为R，C≥3πR/4。
阀板组件30还包括排气阀片32。排气阀片32位于阀板31与气缸盖20之间，排气阀片32的中部设置有排气阀片吸气口321，位于排气阀片吸气口321的一侧设置有供定位组件穿过的排气阀片限位孔322。这样设置能够方便排气阀片32安装，同时增加了该阀板组件的可靠性。
排气阀片32的位于排气阀片限位孔322与排气阀片吸气口321之间开设有第一镂空结构，阀板排气通孔314与第一镂空结构相连通，位于第一镂空结构的侧壁设置有第一舌形阀片323，第一舌形阀片323用于打开或关闭阀板排气孔311。这样设置能够进一步地提高阀板组件的可靠性。当第一舌形阀片323位于打开位置时，第一舌形阀片323与气缸盖20相抵接。当第一舌形阀片323位于关闭位置时，第一舌形阀片323与气缸盖20具有距离地设置。
其中，气缸盖20的朝向排气阀片32一侧设置有与第一舌形阀片323相配合的限位台阶21。限位台阶21的台面的高度从第一舌形阀片323的头部至第一舌形阀片323的尾部逐渐升高。这样设置使得当第一舌形阀片323位于打开位置时，第一舌形阀片323贴合在限位台阶21，这样能够使得第一舌形阀片323受到平衡的排气压力应力的作用，有效地防止了第一舌形阀片323断裂，提高了第一舌形阀片323的适用寿命。
阀板组件30还包括气缸盖垫片33。气缸盖垫片33位于排气阀片32与气缸盖20之间，气缸盖垫片33的中部设置有气缸盖垫片吸气口331，位于气缸盖垫片吸气口331一侧设置有气缸盖垫片限位孔332，气缸盖垫片33上设置有与第一镂空结构相连通的第二镂空结构，第 二镂空结构位于气缸盖垫片限位孔332与气缸盖垫片吸气口331之间。这样设置能够方便气缸盖垫片33安装在气缸座上，同时提高了压缩机的密封性。
进一步地，气缸盖垫片吸气口331的面积大于或等于排气阀片吸气口321的面积，排气阀片吸气口321的面积大于或等于阀板31的阀板吸气口313的面积。这样设置能够使得压缩机进气顺畅。
进一步地，气缸盖垫片33的外边缘的型线、排气阀片32的外边缘的型线均与阀板31的外边缘的型线相同。这样设置能够有效地减小整个阀板组件的加工材料，继而有效地节约了压缩机的生产成本。
阀板组件30还包括吸气阀片34。吸气阀片34位于阀板31与气缸座10之间，吸气阀片34的中部设置有第二舌形阀片341，第二舌形阀片341用于打开或关闭阀板吸气口313，吸气阀片34上设置有供定位组件穿过的吸气阀片限位孔342。这样设置能够有效地提高压缩机的可靠性。
其中，吸气阀片限位孔342位于第二舌形阀片341的尾部处，第二舌形阀片341的腰部设置有吸气阀片排气孔343，吸气阀片34的位于第二舌形阀片341的一侧设置有与阀板排气通孔314相连通的吸气阀片排气通道344。
进一步地，阀板组件30还包括吸气阀片垫片35。吸气阀片垫片35位于吸气阀片34与气缸座10之间，吸气阀片垫片35的中部设置有吸气阀片通孔351，吸气阀片通孔351的边缘处设置有供定位组件穿过的吸气阀片垫片限位孔352，位于吸气阀片垫片限位孔352的一侧设置有与吸气阀片排气通道344相连通的吸气阀片垫片排气通孔353。这样设置能够进一步地提高阀板组件的密封性。
吸气阀片垫片排气通孔353的直径大于或等于吸气阀片排气通道344的直径，吸气阀片排气通道344的直径大于或等于阀板排气通孔314的直径。这样设置能够使得压缩机排气更加顺畅。
优选地，阀板31的厚度为L，其中，1.5mm≤L≤2.5mm。这样设置能够有效地减小了阀板组件的厚度，继而有效地减小了压缩机整体减小余隙容积，提高了压缩机的实用性。
如图3所示，气缸座10具有活塞室11，朝向气缸盖20一侧的活塞室11的端部的至少部分的外轮廓型线设置成弧线。这样设置能够使得阀板组件的外轮廓型线与气缸的外轮廓型线相一致，有效地减小了气缸座的加工材料，继而有效地减小了压缩机的生产成本和占用的安装空间。
优选地，第一定位件和第二定位件中的一个设置于活塞室11的端面上。如图3所示，定位孔42和排气通孔14开设在活塞室11的端面上。连接件的连接孔13开设在气缸座上。优选地，连接件为螺钉12，螺钉12为多个。
上述实施例中的压缩机还可以用于制冷设备技术领域，即根据本申请的另一方面，提供了一种制冷装置，包括压缩机，压缩机为上述实施例中的压缩机。
具体地，通过采用近似圆形阀组，有效地解决阀组材料浪费问题，通过在阀组上开设限位孔，有效地解决阀组安装时串动的问题。采用本申请中的阀板组件，省去了一个升程限位器，与方形缸头阀组配合相比，吸气阀片与排气阀片完全与缸孔配合，材料使用率比较高，节省阀组零件的生产加工成本，提高整机的经济性。由于阀组上开设有限位孔，靠气缸盖上的定位柱进行安装限位，阀板组件上省去螺钉孔，提高了阀组加工经济性与安装的便利性。
采用该阀板组件，不用再铆压升程限位器来固定排气阀片，而是在气缸盖上铸一个倾斜的限位台阶来替代升程限位器，进而提高了阀组组件安装的便利性。
图2为本申请阀组组件与缸头爆炸结构示意图，阀组组件与缸头包括气缸座、气缸盖、吸气阀片垫片、吸气阀片、阀板、排气阀片、气缸盖垫片，其中气缸座包含有排气通孔、定位孔、螺钉孔，活塞压缩机泵体由曲轴(图未示出)、活塞(图未示出)、连杆(图未示出)、气缸座与阀组组件组成，曲轴在电机的带动下带动连杆与活塞在气缸座腔体中依靠阀组组件进行吸气、压缩、排气、膨胀过程。
图3为压缩机的实施例的爆炸结构示意图，阀板组件开始正常工作时，是由压缩机的电机拖动曲轴转动，曲轴经连杆带动活塞在气缸活塞室中对冷媒进行工作，当吸气，低温低压的冷媒经吸气消音器出口经由气缸盖垫片吸气口、阀板吸气口，使得吸气阀片打开，冷媒吸入到气缸座的活塞室中，并在气缸座的活塞室中进行压缩，当排气时，吸气阀片压紧阀板吸气口，高温高压的气体从经吸气阀片排气孔、阀板排气孔，使得排气阀片打开，气缸盖中的限位台阶替代升程限位器，气体进入到气缸盖中，然后经阀板排气通孔、吸气阀片通孔、吸气阀片垫片通孔进入到气缸座中的排气通孔，经由排气通孔进入到排气消音腔中，然后从排气消音腔中沿着内排气管排出。通过采用圆形阀组通过采用圆形阀板组件结构，与传统的方形阀板组件结构相比，省去了升程限位器，同时阀板组件与圆形气缸的缸孔(活塞室的端部)完全配合，材料使用率比较高，极大的提高了零件加工的经济性。其中吸气阀片垫片排气通孔的直径要稍大于吸气阀片排气通孔的直径，吸气阀片排气通孔的直径要再稍大于阀板排气通孔的直径，吸气阀片排气孔的直径要稍大于阀板排气孔的直径，以保证排气更加的流畅；气缸盖垫片吸气口的面积稍大于或等于排气阀片吸气口的面积，排气阀片吸气口的面积要稍大于阀板吸气口的面积以保证吸气更加的顺畅，阀板的厚度为1.5mm～2.5mm，与传统的方形厚阀板相比，余隙容积更小，从而能够提升压缩机的性能。此外排气阀片与限位台阶之间还未接触时也要保证合理的间隙，以保证排气阀片的寿命与排气效率。
通过在阀组组件上开设限位孔，依靠气缸盖上的定位柱进行安装定位，而不用在阀组组件上打螺钉孔，提高了阀组加工的经济性，由于省去了升程限位器，不用再铆压升程限位器来固定排气阀片，而是在气缸盖上铸一个倾斜的台阶来替代升程限位器，进而提高了阀组组件安装的便利性。此外定位柱还具有防反的功能，定位柱的形状可以是方形、锥形只要能够起到防止阀板组件装反的作用即可。
除上述以外，还需要说明的是在本说明书中所谈到的“一个实施例”、“另一个实施例”、“实施例”等，指的是结合该实施例描述的具体特征、结构或者特点包括在本申请概括性描述的至少一个实施例中。在说明书中多个地方出现同种表述不是一定指的是同一个实施例。进一步来说，结合任一实施例描述一个具体特征、结构或者特点时，所要主张的是结合其他实施例来实现这种特征、结构或者特点也落在本申请的范围内。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
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。
