具体地，密封块10包括刚性密封面11，刚性密封面11能够抵靠阀芯201，以对密封块10与阀芯201进行装配密封；密封圈30包括柔性密封面31，柔性密封面31能够抵靠阀体202，以对密封圈30与阀体202进行装配密封。也就是说，密封结构装配于阀芯201与阀体202之间时，能够对阀芯201进行硬密封，对阀体202进行软密封，以此实现对阀芯201与阀体202之间软硬结合的有效密封，分别实现动态侧和静态侧两侧的密封。需要说明的是，密封结构装配至阀芯201与阀体202之间的位置，密封块10部分伸入至阀体202内，且密封圈30的柔性密封面31能够抵靠在阀体202的管口边沿2021上。
可以理解，密封结构在密封圈30与密封块10之间设置有弹性件20，以此确保该密封结构对阀芯201与阀体202之间装配的密封性，避免阀芯201与阀体202之间发生泄漏；另外，利用弹性件20的结构设置，使得该密封结构上用于密封阀芯201与阀体202的刚性密封面11与柔性密封面31之间的距离可大幅度的调整，进而便于将该密封结构装配至阀芯201与阀体202之间。
如图3、图5所示，刚性密封面11设置为匹配于阀芯201上球面2011的圆弧面111，以此具体实现该刚性密封面11的结构设置，实现增加刚性密封面11抵靠在阀芯201上时两者之间的贴合度的效果，从而确保该刚性密封面11抵靠在阀芯201上时实现两者密封的效果。当然，刚性密封面11不局限为图示所示，对本领域技术人员来说，可将刚性密封面11设置为平面，在此就不展开阐述。
如图1、图2，密封圈30上柔性密封面31包括多个环形凸面311，多个环形凸面311依次间隔地设置于密封圈30上朝向阀体202的一端部上，以此具体实现该柔性密封面的结构设置，从而确保该柔性密封面31抵靠在阀体202上时实现两者密封的效果并且提供弹性余量补充以增强密封效果。在一些实施例中，密封圈30可采用X型密封圈。当然，需要说明的是，柔性密封面31不局限为图示所示，对本领域技术人员来说，可将柔性密封面31设置为平面、弧面、或者其它形状。
如图1所示，弹性件20以预压缩的方式安装于密封块10与密封圈30之间，且弹性件20能够朝相反的方向分别推顶密封块10及密封圈30，以将该弹性件20装配在密封块10与密封圈30之间，从而使得该密封块10上刚性密封面11能够紧靠在阀芯201，同时密封圈30上柔性密封面31能够挤压阀体202并发生变形，以此确保该密封结构对阀芯201与阀体202的装配密封性。
具体地，该弹性件20包括多个波形弹簧210，多个波形弹簧210层叠设置，以此具体实现该弹性件20的结构设置，利用波形弹簧210的结构特性，能够延长弹性件20使用寿命的作用。该弹性件20也可设置为单个波形弹簧。当然，弹性件20也不局限为图示所述的波形弹簧210，对本领域技术人员来 说，可将弹性件20设置为压缩弹簧等其它弹簧。
如图1、图2所示，该密封结构还包括隔垫40，隔垫40设置于密封圈30与弹性件20之间的位置，且弹性件20能够通过隔垫40抵推密封圈30，以使密封圈30的柔性密封面31抵靠在阀体202上，以此提高该密封圈30受力的稳定性。
具体地，该隔垫40设置为平垫410，以此具体实现该隔垫40的结构设置。
如图3所示，该密封块10包括挡块部110及套筒部120，刚性密封面11设置于挡块部110上远离套筒部120的一端部上，套筒部120朝阀体202的方向部分插入至阀体202内，以此具体实现该密封块10的结构。
其中，该挡块部110上设置有凸台1110，刚性密封面11设置于凸台1110上远离挡块部110的一端面上，以此具体实现刚性密封面11在该挡块部110上的结构设置，使得该密封结构在阀芯201与阀体202之间装配时，可用压缩该密封结构的工装压板203在挡块部110上的贴靠进行限位，以便于将该密封结构装配至阀芯201与阀体202之间的位置。
进一步地，该挡块部110上设置有多个连接凸筋1120，多个连接凸筋1120依次间隔设置并与凸台1110的外周壁1111连接，以进一步提高工装压板203与挡块部110贴靠时接触的稳定性。需要说明的是，该工装压板203上开设有匹配于连接凸筋1120的凹槽2031。
如图4所示，密封结构装配至阀体202与阀芯201时，可先将弹性件20、隔垫40及密封圈30依次套接在密封块10的套筒部120上，然后将密封块10上套筒部120对准阀体202插入直至密封圈30上柔性密封面31抵靠阀体202的管口边沿2021，以此实现该密封结构在阀体202上的装配，然后再用工装压板203抵压密封块10的挡块部110并压缩弹性件20，最后再将阀芯201放 入至阀体202内，以此实现将密封结构装配至阀芯201与阀体202之间的位置，从而便于装配。
另外，本申请的密封块10及密封圈30上分别设置有防腐涂层，以满足该密封结构应用于阀芯201与阀体202之间工作时的使用需求。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
