Problems solved by technology
[0004] The present invention mainly provides a connection device between a lead plug and a cable sleeve, which is used to solve the problems in the above-mentioned background technology that with the increase of the service life of the equipment and the wear and tear caused by the vibration during the operation of the steam turbine, the connection part of the aviation lead plug often becomes loose. And the phenomenon of damage to the control cable, in severe cases, it may even cause the internal welding part of the aviation plug to break, the lead wire connection is interrupted, and the technical problem of the valve closing accident occurs instantaneously.

The invention provides a connecting device for a lead plug and a cable sleeve, which comprises a valve body, one side of the valve body is detachably connected with a lead aviation plug, a cable is inserted in the middle of the lead aviation plug, and the cable is detachably connected with the valve body; the other end of the cable penetrates through a cable sleeve, and the cable sleeve is detachably connected with the lead aviation plug through a connecting assembly. According to the invention, by arranging the connecting assembly, the spiral connection of the cable sleeve and the lead aviation plug is effectively prevented by using the connecting assembly, so that the abnormal phenomena of falling, cable collision and abrasion and the like in the use process are prevented.
Description
technical field [0001] The invention relates to the field of digital electro-hydraulic control of steam turbines in industrial production, in particular to a connection device for a lead plug and a cable casing. Background technique [0002] At present, the main function of the electro-hydraulic converter control (DEH) valve in industrial production is that it receives the output power and speed signal of the turbogenerator from the distributed control system (DCS) to change the opening of the speed regulating valve, thereby closed-loop control The speed and output power of the turbogenerator are the load. The lead wire method of the steam turbine electro-hydraulic converter control valve is that the lead wire is welded on the pin to connect with the special socket inside the aviation plug, and there is usually no protective sleeve or protection and locking device on the outside. [0003] With the increase of the service life of the equipment and the wear and tear caused by...
