Be electrically connected the display unit that is used for showing described valve opening or closed condition with described data processing equipment.
As preferably, the system for monitoring the valve switch state of the present utility model also comprises the guard grating that is connected between described approach switch and the described data processing equipment.
As preferably, described approach switch is arranged on the valve flange of described valve.
As preferably, described approach switch is arranged on the valve flange of described valve by support.
As preferably, described data processing equipment is PLC or RTU.
As preferably, the system for monitoring the valve switch state of the present utility model also comprises the explosion-proof wiring box for the described guard grating of accommodating installation.
Compared with prior art, the beneficial effect of the system for monitoring the valve switch state of the present utility model is:
1, it is convenient that the system architecture for monitoring the valve switch state of the present utility model is simple, installation is transformed.
2, the system for monitoring the valve switch state of the present utility model can obtain the status information of valve at any time, patrols and examines and need not the operator scene, has reduced operator's labor intensity, and has improved safety coefficient.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to restriction of the present utility model.
As shown in Figure 1, a kind of system for monitoring the valve switch state of embodiment of the present utility model comprises approach switch 1, data processing equipment 2 and display unit 3: approach switch 1 is arranged near valve 4 mechanical shaft 41 positions that are used for monitoring valve 4; Data processing equipment 2 is electrically connected the electrical signal that is used for receiving and processing approach switch 1 with approach switch 1; Display unit 3 is electrically connected with data processing equipment 2 and be used for shows that valve 4 is opened or closed condition.If think to understand simultaneously unlatching or the closed condition of a plurality of valves 4, approach switch 1 then is set respectively near a plurality of valves 4, a plurality of approach switchs 1 can be connected to simultaneously on the data treatment device 2 and then be electrically connected with display unit 3.Can certainly connect respectively a data treatment device 2 by each approach switch, and then data processing equipment 2 is electrically connected with display unit 3.
System for monitoring the valve switch state of the present utility model can show each valve 4 residing states by display unit 3, with the on off state that the easy-to-operat personnel understand each valve 4, patrols and examines to the scene and need not operator.
As long as the setting position of approach switch 1 can guarantee mechanical shaft 41 and be positioned at its induction region, therefore, approach switch 1 namely can be arranged on the valve 4, also can and valve 4 be arranged near the valve 4 by the support (not shown) without annexation.But for easy for installation and be unlikely to affect miscellaneous part, preferably approach switch 1 is arranged on the valve flange 42 of valve 4 in the present embodiment.Further preferably approach switch 1 is arranged on the valve flange 42 of valve 4 by support, can utilizes the original bolt of valve flange to be connected with described support, then fixing with nut.
When on the equipment that uses to the environment at rock gas for the system applies that monitors the valve switch state of the present utility model, all on-site electrical equipments must adopt technological processing for explosion protection feature, therefore need to install guard grating 5 additional, guard grating 5 can be between safety zone and hazardous area two-way transmission electrical signal, and can limit safety zone that barrier for some reason causes to hazardous area and energy transmission.Approach switch 1 is connected with data processing equipment 2 by guard grating 5.After the change in location of mechanical shaft 41 changes the on off state of valve, trigger the change in electric of approach switch 1, by guard grating 5 switching value of one 24 volts of electrical signal outputs is changed, judge the state of valve 4 by the voltage change of 0 volt and 24 volts.
A kind of preferred version as present embodiment, system for monitoring the valve switch state of the present utility model also comprises the explosion-proof wiring box 6 for accommodating installation guard grating 5, guard grating 5 is placed in the inside of explosion-proof wiring box 6, and then the signal cable 51 of guard grating 5 is connected to data processing equipment 2 from explosion-proof wiring box 6 inside by Coating Steel Pipe.
As the another kind of preferred version of present embodiment, data processing equipment 2 can adopt PLC(programmable logic controller (PLC) Programmable Logic Controller) or RTU(Remote Terminal Unit remote terminal control device).Display unit 3 adopts computer display 8.Computer display 8 is arranged in the station control monitoring night shift room 7, and the staff only need watch computer display just can know the opening state of valve 4.As shown in Figure 2, closing or opening state by computer display 8 remote reviewing valves 4.
