Fig. 2 be the utility model proposes a kind of valve mechanism locking system logical circuitry.
In figure:1 handcart track, 2 times valve mechanisms, valve mechanism on 3,4 times valve mechanism locking holes, valve mechanism on 5 Locking hole, 6 roller switches.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.
Reference picture 1-2, a kind of valve mechanism locking system, including handcart track 1, lower valve mechanism 2, upper valve mechanism 3, Lower valve mechanism locking hole 4, upper valve mechanism locking hole 5 and roller switch 6, the side of the handcart track 1 is provided with roller Switch 6, the side of the handcart track 1 is provided with lower valve mechanism 2 and upper valve mechanism 3, and lower valve mechanism 2 is located at upper work The top of door mechanism 3, the upper valve mechanism 3 is provided with upper valve mechanism locking hole 5, and the lower valve mechanism 2 is provided with down Locking electricity is mounted in the hole of valve mechanism locking hole 4, the upper valve mechanism locking hole 5 and lower valve mechanism locking hole 4 Magnet DST, the rolling switch 6 is provided with rolling switch auxiliary contact H1, the other end of the rolling switch auxiliary contact H1 It is electrically connected with bus and circuit charged display device H2, the other end of bus and circuit charged display device the H2 auxiliary contacts Being electrically connected with latching electromagnet DST, the latching electromagnet DST includes magnet exciting coil and latching electromagnet locking bar, the lower work The side of door mechanism 2 and upper valve mechanism 3 is provided with safety warning or safety alarming and identifying.
In the utility model, one latching electromagnet DST is respectively installed in the outside of valve mechanism up and down, its locking bar and work is utilized The cooperation of door drive mechanism, realizes the mechanical locking of valve mechanism, and the track side surfaces in switch gear room install one with auxiliary contact Roller switch 6, coordinates with the chassis vehicle of wheelbarrow switch, controls cut-offfing for its auxiliary contact, electrical control:By bus and circuit band Electric display device H2 normally opened auxiliary contact is respectively connected to corresponding latching electromagnet wire loop, while being controlled back accordingly The normally closed auxiliary contact of roller switch 6 is accessed on road, to control latching electromagnet coil DST break-make, in order to not influence to switch hand The normal operating of car and prevent latching electromagnet coil it is long-term it is powered burn out, when wheelbarrow switch is exited to maintenance position, utilize The normally closed auxiliary contact connection electric loop of roller switch 6, locking valve mechanism, when wheelbarrow switch is pushed into testing position, Electric loop is disconnected using the normally closed auxiliary contact of roller switch, the locking to valve mechanism is released.Set at lockable mechanism Obvious safety warning, alarming sign, above and below switch gear room on valve baffle plate spraying " bus is powered, forbids opening!", " circuit It is powered, forbid opening!" and " powered " and " forbidding " icon, improve security.
