Problems solved by technology
[0003] At present, the opening and closing of the doors of large passenger cars and buses on the market are controlled by two-position five-way solenoid valves, and the opening and closing of the door is realized by switching different working ports through the two-position five-way solenoid valves. However, the two-position five-way solenoid valves When the electromagnetic valve is switching the working port, if the electromagnetic control part fails, it will cause the switching of the working port to fail, which will easily cause the door to fail to open or close, especially when there are many people getting off the car. cause panic, prone to accidents

Description
technical field [0001] The invention relates to the technical field of valves, in particular to a safety reversing solenoid valve. Background technique [0002] Valve products are widely used in fluid control in various technical fields, and two-position five-way valve is one of them, which is well known to people. The two-position five-way valve can be divided into three types: manual type, electromagnetic type and air control type according to different structures. [0003] At present, the opening and closing of the doors of large passenger cars and buses on the market are controlled by two-position five-way solenoid valves, and the opening and closing of doors are realized by switching different working ports through the two-position five-way solenoid valves. However, two-position five-way solenoid valves When the electromagnetic valve is switching the working port, if the electromagnetic control part fails, it will cause the switching of the working port to fail, which ...
