Problems solved by technology
[0002] Traditional responders use contact micro switches to generate signals. When the elastic metal sheets of micro switches are used for too long, they are prone to deformation, fatigue and no signal; therefore, contact micro switches often have a short service life and Difficult to maintain, when a part of the traditional echoer fails, the entire echoer can only be replaced; and the contact micro switch is point-to-point contact, the detection range is small, and the signal feedback is not comprehensive

The invention belongs to the technical field of position monitoring switches, and relates to a memory type valve position monitoring switch and a valve. The memory type valve position monitoring switch comprises a shell, an executor arranged on the shell and at least one induction switch. The induction switch is arranged on the shell in a manner of surrounding the executor. A trigger part is arranged on the side wall of the executor and is used for triggering the induction switch. The vertical connecting line between the trigger part and the axis of the executor and the output direction of theexecutor form a certain angle which ranges from 1 to 60 degrees. Through the trigger part and the trigger switch, the valve is controlled to be on and off, the motion state of the valve is stably andcontinuously indicated, meanwhile, an indication lamp and an indication mark are arranged, the on and off state of the executor and the valve can be conveniently checked, in addition, the service life of the position monitoring switch can be prolonged, assemblies can be independently replaced, and cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of echo devices, and relates to a memory type valve echo device and a valve. Background technique [0002] Traditional responders use contact micro switches to generate signals. When the elastic metal sheets of micro switches are used for too long, they are prone to deformation, fatigue and no signal; therefore, contact micro switches often have a short service life and Difficult to maintain, when a part of the traditional echoer fails, the entire echoer can only be replaced; and the contact micro switch is point-to-point contact, the detection range is small, and the signal feedback is not comprehensive. Contents of the invention [0003] The object of the present invention is to provide a memory-type valve feedback device and a valve to prolong the service life of the feedback device. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005]...
