具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型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实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
请参阅图1-4，本实用新型提供的一种实施例：氢气回收装置高压差多级低噪音套筒调节阀，包括阀盖1、主体4、阀芯9和阀座10，主体4的顶端设置有阀盖1，且主体4的底端设置有阀座10，阀盖1的底端设置有密封块13，且阀座10的顶端设置有与密封块13配合的密封槽12，并且密封块13的横截面呈环形，同时密封块13的外侧壁包裹有吸水膨胀橡胶套14；
使用时，由于密封块13嵌入密封槽12的内部，因而增强了装置整体的密封性能，此外，当装置长期使用时密封块13发生磨损，体积减少时，渗透的水体不仅会被吸水膨胀橡胶套14吸收，而且吸水膨胀橡胶套14吸收水体后发生膨胀，体积变大，牢牢地堵住密封槽12，从而进一步提升了装置的密封性能，提升了装置的使用效果；
阀盖1底部的两端皆设置有与阀座10连接的固定螺栓5，且阀盖1内部顶端的中间位置处设置有阀杆3，阀杆3的外侧壁缠绕有弹簧2，且阀杆3底端阀座10的内部设置有阀芯9，阀芯9的内部安装有主套筒8，主套筒8上均匀设置有第一分套筒21，且第一分套筒21上均匀设置有呈同心圆排列的第一节流孔22，并且主套筒8上均匀设置有第二分套筒24，且第二分套筒24上均匀设置有呈同心圆排列的第二节流孔23，同时第一节流孔22的数量等于第二节流孔23的数量，且第一节流孔22的位置和第二节流孔23的位置一一对应呈错位重叠排布；
使用时，流经主套筒8的水体会在第一节流孔22和第二节流孔23的作 用下，依次分散成多股小体积的水体流出，从而减轻了水体产生的压力，提升了装置的使用效果；
阀座10的一端设置有与主套筒8内部相连通的进水口7，且阀座10的另一端设置有与主套筒8内部相连通的出水口11，进水口7和出水口11皆与阀座10之间构成挤压一体成型结构，且进水口7和出水口11远离阀座10的一端皆设置有法兰盘6，使其即优化了装置的结构，又便于装置与相应的水管或设备进行固定安装，从而增强了装置的功能性，主体4的外侧壁和内侧壁皆涂覆有氧化铜耐腐蚀层19，主体4侧壁的内部设置有加强层15，且加强层15的内部均匀设置有呈等间距排列的加强筋16，并且加强筋16的横截面呈工字型，使其增强了装置的结构强度，从而有利于延长装置的使用寿命，加强层15一侧主体4侧壁的内部设置有真空腔20，且真空腔20的内部均匀设置有呈蜂窝状排列的消音孔18，同时消音孔18的内部填塞有吸音矿棉17，使其利用真空环境下声波不能传播的原理，以及吸音矿棉17吸收声波能量的作用，减轻了装置使用过程中所产生的噪音污染，实现了环保的优点，符合时代的发展主题。
工作原理：使用时，工作人员首先将阀盖1底端的密封块13插入阀座10顶端的密封槽12内部，继而利用固定螺栓5将阀盖1和阀座10之间固定牢固，然后利用法兰盘6的作用，将进水口7或者出水口11与氢气回收装置上相应的水管进行连接，经由进水口7进入的大体积水体会通过主套筒8，再通过出水口11排出，而在主套筒8内部，水体会在第一节流孔22和第二节流孔23的作用下，被依次分解为一小股一小股的水体流出，实现了分级降压的作用，提升了装置的使用效果，此外，由于该装置设置有真空腔20、消音孔18和吸音矿棉17，使得装置即利用真空环境下声波不能传播的原理，又利用吸音矿棉17吸收声波能量的作用，减轻了装置使用过程中水体碰撞所产生的噪音污染，实现了环保的优点，符合时代的发展主题。
对于本领域技术人员而言，显然本实用新型不限于上述示范性实施例的细节，而且在不背离本实用新型的精神或基本特征的情况下，能够以其他的具体形式实现本实用新型。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本实用新型的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本实用新型内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
