Anti-freezing sampler

The utility model provides an anti-freezing sampler which comprises a shell, an inlet is formed in the shell, and a mounting cavity is formed in the shell; the valve core assembly is movably mounted in the mounting cavity; the control part is connected with the valve element assembly and used for driving the valve element assembly to move so as to control opening and closing of the inlet; the valve element assembly comprises a valve rod and a valve element, the first end of the valve rod is connected with the control part, and the valve element is detachably connected with the second end of the valve rod. When the valve core is pierced by silt, a worker can directly detach the valve core, replace the valve core and put the valve core into use again without replacing the whole anti-freezingsampler, so that the cost is effectively saved. 本实用新型提供了一种防冻取样器，该防冻取样器包括壳体，壳体上设置有入口，壳体内部设置有安装腔；阀芯组件，阀芯组件可移动地安装在安装腔中；控制部，控制部和阀芯组件连接，用于驱动阀芯组件运动，以控制入口的打开和关闭；阀芯组件包括阀杆和阀芯，阀杆的第一端和控制部连接，阀芯和阀杆的第二端可拆卸地连接。当阀芯被泥沙刺坏，工作人员可以直接将阀芯拆卸下来，进行更换
