The invention provides a micro-deformation anti-leakage valve element with a cooling flow channel, and belongs to the technical field of valves. According to the micro-deformation anti-leakage valve element with the cooling flow channel, the cooling flow channel is machined inside the valve element, therefore, the temperature of the surface of a valve body can be locally changed, then in the high-temperature or low-temperature environment of the valve element, inconsistent deformation is generated due to the temperature difference, and then the separated valve element and a sealing element arein close contact again to realize sealing. According to the valve element, the situation of leakage of the valve element can be effectively avoided. 本发明提出一种带有冷却流道的微变形抗泄漏阀芯，属于阀门技术领域。本发明提出在阀芯内部加工出一条冷却流道，可以局部改变阀体表面的温度，使阀芯在高温或低温环境下，因为温差的原因产生不一致的变形，使分离的阀芯和密封件重新紧密接触实现密封。本发明所述阀芯能够有效避免阀芯的泄露问题。
