Differential pressure controller

The invention relates to the technical field of differential pressure switches, in particular to a differential pressure controller which comprises a shell and a cover, a slot is formed in one side, close to the cover, of the shell wall of the shell, a square plug board is integrally arranged on one side, close to the shell, of the cover, and the plug board is matched with the slot. Clamping assemblies are arranged on the outer walls of the two sides of the shell and used for clamping and fixing the inserting plate so that the cover body can be fixedly installed on the shell. The device can be conveniently assembled and disassembled, and can be conveniently and rapidly disassembled and overhauled when the internal structure goes wrong. 本发明涉及压差开关技术领域，尤其为一种压差控制器，包括壳体和盖体，壳体的壳壁靠近盖体的一面开设有插槽，盖体靠近壳体的一面连一体式设有方形的插板，插板与插槽相匹配，壳体的两侧外壁均设有卡接组件对插板进行卡接固定使盖体固定安装在壳体上。本发明可以方便装拆，便于在内部结构出现问题时，快速拆卸检修。
