The invention relates to a five-opening two-position electromagnetic valve. The five-opening two-position electromagnetic valve comprises a valve body, a coil and a terminal; the valve body is provided with an air inlet, a first outlet, a second outlet, a third outlet and a fourth outlet; the outer end of the coil is locked by a coil fastening nut; the five-opening two-position electromagnetic valve is characterized in that the coil fastening nut comprises a nut body; the inner wall of a center hole of the nut body is provided with an internal thread; a plurality of rows of salient points are arranged on the inner wall of the center hole of the nut body and along the circumferential direction; each row comprises a plurality of salient points; adjacent salient points have a certain distance; the diameter of each salient point is smaller than the thread pitch of the internal thread; the salient points are higher than the thread teeth. By structural improvement of the coil fastening nut on the electromagnetic valve, the five-opening two-position electromagnetic valve provided by the invention is capable of improving the problem that the coil fastening nut is easily slipped on the teeth and is easily loosened during installation and application.
Description
technical field [0001] The invention relates to a solenoid valve, in particular to a five-port two-position solenoid valve used for controlling a pneumatic actuator. Background technique [0002] The five-port two-position solenoid valve adopts a two-position five-way structure. The two positions represent two working positions, that is, only one inlet and one outlet are working in any working state, and the five-way means that there are five connection ports. The common air source solenoid valve consists of one inlet, two outlets (one with power on and one with power off), and two exhaust ports (one with power on and one with power off). [0003] At present, the solenoid valve used in the pneumatic valve control system is generally made of reinforced nylon 66 engineering plastics for the coil fastening nut, and most of them are in the form of thread fastening. In practical applications, there are often phenomenons that the threaded fastening structure will slip and loosen ...
