[0009] Preferably, a guide groove is arranged on the position corresponding to the limiting protrusion of the side of the box body, a push block is movably connected in the guide groove, a handle is fixed on the surface of the push block, and the push block can lift the clamping piece.

[0010] Through adopting the technical scheme, the push block is arranged, the push block can embed the clamping piece, the clamping piece is lifted away from the limiting protrusion, and therefore the door frame can be quickly opened.

[0011] Preferably, in order to facilitate the push block to quickly lift the clamping piece, one end of the clamping piece is provided with a turned-up edge, and one end of the push block close to the turned-up edge is provided with an inclined surface.

[0012] Preferably, in order to improve the sealing performance between the door frame and the box body, a groove is arranged on one side of the door frame close to the box body, and a sealing gasket is arranged in the groove.

[0013] The door frame is provided with a lock groove corresponding to the position of the door lock.

[0014] The protection cover is provided with turned-up edges on both sides, and the box body is provided with a plug-in groove corresponding to the position of the turned-up edges.

[0015] In summary, the electric valve control box with the emergency door opening mechanism has at least one beneficial technical effect: the electric valve control box with the emergency door opening mechanism is provided with the emergency door opening mechanism, in an emergency, the operator can lift the protection cover upward to separate the protection cover from the box body, and then push the clamping piece away from the limiting protrusion, so that the door frame can be quickly opened as a whole for operation, emergency treatment can be quickly performed, and risks can be avoided.
