The embodiment of the invention relates to the technical field of valve assemblies, and particularly discloses a valve assembly, a pneumatic massage system and a seat, the valve assembly comprises a valve body, a valve core and an actuator, the valve body comprises a circuit board, the valve body is provided with a valve cavity, and the valve body is provided with a first medium opening, a second medium opening and a third medium opening which are communicated with the valve cavity; the valve element comprises a sliding sleeve, a first valve rod, a second valve rod and a first elastic piece, the sliding sleeve is arranged in the valve cavity, the first valve rod is located at one end of the sliding sleeve, the second valve rod is located at the other end of the sliding sleeve, the first elastic piece is connected to the first valve rod and the second valve rod, and the actuator is connected with the circuit board. The actuator is used for actuating the sliding sleeve to move among the first position, the second position and the third position. By means of the mode, the state that the first valve rod opens the first medium opening and the second valve rod opens the second medium opening at the same time can be avoided, the supply pressure of the air pump to other air bags is guaranteed, and therefore the air supply efficiency of the other air bags cannot be affected.
本发明实施例涉及阀组件技术领域,尤其公开了一种阀组件、气动按摩系统及座椅,包括阀体、阀芯和致动器,阀体包括电路板,阀体具有阀腔,阀体开设有与阀腔连通的第一介质开口、第二介质开口和第三介质开口,阀芯包括滑套、第一阀杆、第二阀杆和第一弹性件,滑套设置于阀腔,第一阀杆位于滑套的一端,第二阀杆位于滑套的另一端,第一弹性件连接于第一阀杆和第二阀杆,致动器与电路板连接,致动器用于致动滑套在第一位置、第二位置和第三位置之间移动。通过上述方式,本发明实施例能够避免同时出现第一阀杆打开第一介质开口和第二阀杆打开第二介质开口的状态,保证气泵对其它气袋的供应压力,从而不会影响其它气袋的供气效率。
