优选地，所述凸起311至少为两个，所述凹槽21至少为两个，每一所述凸起311对应收容于每一所述凹槽21内。多个凸起311的设置和多个凹槽21的形成，使得所述连接管30与第二阀片20的连接更加紧固。
进一步地，所述连接管30包括第一连接管31及第二连接管32，所述凸起311设于所述第一连接管31的背离第二连接管32的一端；所述第二连接管32的外壁设有第一齿轮321，所述贯通旋钮40的内壁设有与所述第一齿轮321啮合的第二齿轮41。这样的设置，使得所述第二连接管32通过其外壁的第一齿轮321与所述贯通旋钮40的第二齿轮41啮合连接，使得所述贯通旋钮40在转动时，能有效带动所述连接管30的转动，保证了所述连接管30与贯通旋钮40连接的紧固性。
需要说明的是，所述第一连接管31的外径大于所述第二连接管32的外径。这样的设置，使得所述第二连接管32与所述贯通旋钮40啮合连接时，其外径较大的第一连接管31与所述贯通旋钮40一端抵接，不会被收容于所述贯通旋钮40管道内，也就使得所述第一连接管31能对所述贯通旋钮40起到抵挡作用，进一步确保了所述连接管30与所述贯通旋钮40连接的稳固性。
进一步地，所述外壳包括阀座50与密封环60，所述密封环60套设于所述贯通旋钮40的连接连接管30的一端外侧，且所述密封环60一端设有外螺纹61，所述阀座50内壁设有与所述密封环60外螺纹61配合的内螺纹（图未示），所述阀座50与所述密封环60的连接形成所述容置腔51。所述密封环60与所述阀座50螺纹连接，同时所述密封环60与所述贯通旋钮40套接，进而通过所述密封环60将所述阀座50与所述贯通旋钮40连接成一个整体。
需要说明的是，所述第二连接管32与所述贯通旋钮40啮合连接并收容于所述密封环60内，所述第一连接管31与所述密封环60一端抵接。具体地，所述密封环60套设于所述贯通旋钮40的与第二连接管32啮合连接的一端的外侧，进而也就是使得所述第二连接管32收容于所述密封环60内，外径较大的第一连接管31与所述密封环60一端抵接，而所述密封环60的远离所述贯通旋钮40的一端外壁设有外螺纹61，并与所述阀座50的内螺纹配合连接，进而也就使得所述第一连接管31、第二阀片20和第一阀片10收容于所述阀座50的容置腔51内，使得所述控制阀的结构更加紧凑。
在本发明的一优选实施方案中，所述控制阀还包括密封圈70，所述密封圈70收容于所述阀座50的容置腔51内，且所述密封圈70与所述第一阀片10的背对第二阀片20的一侧抵接。所述密封圈70的设置，能有效确保所述第一阀片10与所述阀座50连接的紧密性。
所述阀座50的形成容置腔51的内壁设有用以卡合所述密封圈70的台阶部（图未示），进而使得所述密封圈70夹合于所述台阶部与第一阀片10之间，进一步确保所述密封圈70的稳固性。
本发明还提出一种热水器，所述热水器包括排污接口和如上所述的控制阀，所述控制阀与所述排污接口连接。需要说明的是，所述控制阀也可以根据实际情况连接于热水器的其他接口。该控制阀的具体结构参照上述实施例，由于本热水器采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
