The invention discloses a control mechanism for an emergency release valve, and belongs to the technical field of hydraulic pressure. The control mechanism comprises a first sequence valve, a second sequence valve, a first flow distributing and collecting valve and a second flow distributing and collecting valve, a swing cylinder comprises a first swing cylinder, a second swing cylinder and a third swing cylinder which are the same in structure, the volume of a rod cavity of the first swing cylinder is as same as that of a rodless cavity of the first swing cylinder, an oil inlet of the first sequence valve is communicated with a rodless cavity of a valve core cylinder, an oil outlet of the first sequence valve is communicated with the rod cavity of the first swing cylinder and a flow collecting port of the first flow distributing and collecting valve, and two flow distributing ports of the first flow distributing and collecting valve are communicated with a rod cavity of the second swing cylinder and a rod cavity of the third swing cylinder. According to the control mechanism, the rod cavities of the first swing cylinder, the second swing cylinder and the third swing cylinder are the same in oil-taking quantity, and synchronous action of the first swing cylinder, the second swing cylinder and the third swing cylinder can be ensured.
