船用液压舵机是操纵舵叶转动的动力来源，舵叶转动使船舶的航向发生变化。液压舵机的动作决定了船舶的航向和安全，所以是船舶上最重要的设备之一。转叶式舵机与舵的匹配性能优于摆缸式舵机和拨叉式舵机，因此被越来越多地应用于多类船舶中。转叶式舵机的阀组设置为控制转叶式舵机的执行机构进行转动，为保证阀组工作状态稳定，需要添加多种阀协同作业，阀的数量越多势必阀组的体积越大，阀组占用的空间过大，给转叶式舵机的设计带来困难。因此，本实施例提供了一种适用于转叶式舵机的阀组，以解决上述问题。
如图1-图3所示，该阀组包括阀板1和设置在阀板1上的液动换向阀2、电磁阀3、液压锁组、顺序阀4和第一溢流阀7。阀板1包括两两相邻的第一面101、第二面102和第三面103。液动换向阀2、电磁阀3和液压锁组设置在第一面101上，液动换向阀2设置在电磁阀3和液压锁组之间，电磁阀3相较于液动换向阀2和液 压锁组更靠近第一面101、第二面102和第三面103相交的顶角。顺序阀4设置在第二面102上，第一溢流阀7设置在第三面103上。该阀组的多个阀设置在阀板1的不同侧面上，可有效利用立体空间，保证相连通的阀之间的距离最短，以实现多个阀的空间布置合理，从而能够减小阀组的体积，提高阀组集成化的程度，使阀组占用空间更小。
在一实施例中，该阀组还包括第一定位件12，液动换向阀2通过第一定位件12与阀板1的第一面101可拆卸连接，可拆卸连接能够降低电磁阀3或阀板1的维修难度，提高维修效率，且有利于阀组上的阀体的再回收。在一实施例中，第一定位件12设置有多个，以保证液动换向阀2与阀板1之间连接牢固。
在一实施例中，该阀组还包括第二定位件13，电磁阀3通过第二定位件13与阀板1可拆卸连接，可拆卸连接能够降低电磁阀3或阀板1的维修难度，提高维修效率，且有利于阀组上的阀体的再回收。在一实施例中，第二定位件13设置有多个，以保证电磁阀3与阀板1之间连接牢固。
为了使顺序阀4、第一溢流阀7和液压锁组的安装更加便捷，在一实施例中，所述液压锁组包括第一液压锁5和第二液压锁6，顺序阀4插接于第二面102上，第一溢流阀7螺纹连接于第三面103，第一液压锁5和第二液压锁6螺纹连接于第一面101。第一溢流阀7上设置有螺纹，第三面103上的通孔的内壁设置有螺纹，第三面103上的通孔的内壁上的螺纹与第一溢流阀7上的螺纹对应设置，即可实现第一溢流阀7与第三面103的螺纹连接。在一实施例中，第一液压锁5和第二液压锁6的外壁上分别设置有螺纹，第一面101上的两个通孔的内壁也分别设置有螺纹，第一面101上的两个通孔的内壁的螺纹与第一液压锁5和第二液压锁6上的螺纹对应，实现了第一液压锁5和第二液压锁6分别螺纹连接在第一面101上。螺纹连接可有效保证第一溢流阀7、第一液压锁5和第二液压锁6与阀板1连接的牢固性。
在一实施例中，电磁阀3的第一控制阀口与液动换向阀2的第一端连通，电磁阀3的第二控制阀口与液动换向阀2的第二端连通，以实现电磁阀3对液动换向阀2的控制。液压锁组包括第一液压锁5和第二液压锁6，第一液压锁5和第二液压锁6分别与液动换向阀2的第一输出阀口和第二输出阀口连通。由于第一输出阀口和第二输出阀口分别与执行机构高的两个腔室连通，并借助压差推动执行机构转动，所以液压锁组的设置保证了负载过大时阀组的正常工作。顺序阀4的第一出油阀口和第一溢流阀7的第一上游阀口连通，第一出油阀口还和电磁阀3 的第二入油阀口连通，顺序阀4与第一溢流阀7的设置能够有效保证通过电磁阀3流入液动换向阀2两端的液压油的油压稳定，从而保证了液动换向阀2的正常工作。
当舵受到波浪、海流及其它漂浮物等特大外负载作用时，舵的扭矩超出转叶式舵机的设定输出扭矩，就需要对阀组进行及时的卸载，防止阀组损坏。因此，在一实施例中，该阀组还包括第二溢流阀8，阀板1包括第四面104，第四面104与第二面102相对设置，第二溢流阀8设置在第四面104上，第二溢流阀8与第一液压锁5连通。在一实施例中，第二溢流阀8设置的位置靠近第一液压锁5所在的位置，以减少二者的连接通路的长度，保证整体结构尺寸最小。在一实施例中，第二溢流阀8螺纹连接于第四面104上，即第二溢流阀8上设置有螺纹，设置有螺纹，第二溢流阀8上的螺纹与第四面104上的通孔的内壁上的螺纹对应，即可实现第二溢流阀8与第四面104的螺纹连接。
在一实施例中，该阀组还包括第三溢流阀9，第三溢流阀9同样设置在第四面104上，第三溢流阀9与第二液压锁6连通。在一实施例中，第三溢流阀9设置的位置靠近第二液压锁6所在的位置，以减少二者的连接通路的长度，保证整体结构尺寸最小。在一实施例中，第三溢流阀9螺纹连接于第四面104上，即第三溢流阀9上设置有螺纹，第四面104上的通孔的内壁设置有与之相应的螺纹，即可实现第三溢流阀9与第四面104的螺纹连接。
由于液动换向阀2的第一入油阀口流入的液压油的油压能够一定程度上表征流入执行机构的腔室内的油压，即执行机构内的高压区的油压，该油压影响执行机构的转动角度和转动速度。因此，为了实时监测液动换向阀2的第一入油阀口的油压，在一实施例中，该阀组还包括第一压力表10，第一压力表10设置在第三面103处，第一压力表10能够与液动换向阀2的第一入油阀口连通。
在一实施例中，该阀组还包括第一测压通路和第一压力表开关14，第一测压通路的第一端连通于第一入油阀口，第一测压通路的第二端依次连通于第一压力表开关14和第一压力表10。在一实施例中，第一压力表开关14与第一压力表10通过二者自身的螺纹实现螺纹连接，以保证连接处的密封性。
由于液动换向阀2的第一回油阀口流出的液压油的油压能够一定程度上表征流出执行机构的腔室内的油压，即执行机构内的低压区的油压，该油压同样会影响到执行机构的转动角度和转动速度。因此，为了实时检测液动换向阀2的第一回油阀口的油压，在一实施例中，该阀组还包括第二压力表11，第二压力 表11同样设置在第三面103处，第二压力表11能够与液动换向阀2的第一回油阀口连通。第一压力表10和第二压力表11设置在同一面上，可便于工作人员的观测。
在一实施例中，该阀组还包括第二测压通路和第二压力表开关15，第二测压通路的第一端连通于第一回油阀口，第二测压通路的第二端依次连通于第二压力表开关15和第二压力表11。在一实施例中，第二压力表开关15与第二压力表10通过二者自身的螺纹实现螺纹连接，以保证连接处的密封性。
