The invention discloses an electronic expansion valve, refrigeration equipment and an automobile. The electronic expansion valve comprises a valve body, a valve rod, a valve element and a sealing assembly, the valve body is provided with a valve port, and a sealing groove is formed in the inner circumferential wall of the valve body in the circumferential direction; the valve rod is arranged in the valve body and is rotatably connected with the valve body; the valve element is movably arranged in the valve body between an opening position and a closing position, one end of the valve rod is in threaded connection with the valve element, when the valve element is located at the closing position, the valve port is closed, when the valve element is located at the opening position, the valve port is opened, and the valve element divides the valve body into a first valve cavity and a second valve cavity; the sealing assembly is arranged in the sealing groove and arranged on the valve element in a sleeving mode, the sealing assembly divides a cavity formed by the sealing groove and the valve element into a first sealing cavity and a second sealing cavity which are not communicated with each other, and the valve body is provided with a first communicating hole communicating the first sealing cavity with the first valve cavity. And a second communicating hole for communicating the second sealing cavity with the second valve cavity is formed in the valve body. The electronic expansion valve can prevent the sealing assembly from being impacted.

    本发明公开一种电子膨胀阀、制冷设备及汽车。电子膨胀阀包括阀体、阀杆、阀芯以及密封组件,阀体具有阀口,阀体的内周壁沿周向设有密封槽;阀杆设于阀体内,并与阀体可转动连接;阀芯在打开位置和关闭位置之间可移动的设于阀体内,阀杆的一端与阀芯螺纹连接,阀芯处于关闭位置时,关闭阀口,阀芯处于打开位置时,打开阀口,阀芯将阀体分隔为第一阀腔和第二阀腔;密封组件设于密封槽内,并套设于阀芯上,密封组件将密封槽与阀芯形成的腔体分隔为互不连通的第一密封腔和第二密封腔,所阀体上设置有连通第一密封腔与第一阀腔的第一连通孔,阀体上设置有连通第二密封腔与第二阀腔的第二连通孔。本发明的电子膨胀阀能够避免密封组件受到冲击。
