Abstract
The utility model discloses the inventory control system with pump valve linkage function, comprise overall control device, valve and pump, wherein overall control device connects valve and the control of opening valve or cutting out by relay, described valve is provided with position limit switch, described position limit switch connects relay, and connects by a road signal of relay the feedback that overall control device carries out valve state, and another road signal connects the start stop switch of described pump.The utility model provides the inventory control system with pump valve linkage function; not only valve and pump are controlled separately; but valve and pump are carried out coordinated signals; can by the state of valve state control pump; thus avoid in conveyance conduit and occur, into having more few phenomenon, protecting conveyance conduit.
Description
Technical field
The utility model relates to a kind of sewage inventory control system, particularly relates to a kind of inventory control system with pump valve linkage function.
Background technique
Along with the development of society, the process of people's environmental pollution is more and more paid attention to, as sewage first to be transported to sewage treatment works carry out process up to standard after could discharge, waste gas could discharge after also having to pass through process, before effluent discharge, blowdown factory needs the sewage transport of oneself being discharged to special sewage treatment works, this just makes to have a very long conveyance conduit between the two, by pump sewage to be smoked at this end of blowdown factory and deliver to sewage treatment works by conveyance conduit, a valve can be increased control to control quantity delivered on conveyance conduit simultaneously.
But existing control system is, inventory control system directly connects valve, when receiving order and needing throttle down, inventory control system control valve is closed, but now pump does not cut out, need manually to close, the expansion of the conveyance conduit between pump and valve will be caused even to burst if pump forgets to cut out, which results in the sewage do not processed and be directly discharged into ectocine environment.
For this situation, the control gear of control valve and pump while of occurring a kind of, it is not only connected with valve, also be connected with pump, the opening and closing of control pump while valve being opened or closes, although this structure can effectively control pump, but there is certain hidden danger, malfunction of the electric relay as connected pump cannot control effectively to pump, just cause the generation of above-mentioned situation, or although valve unlatching is not but opened completely, and the lacking of pump having more of opening that this just makes sewage enter completely, thus cause sewage expansion damage pipeline in conveyance conduit.
For above-mentioned situation, we need one can either simultaneously control valve and pump, both can also be carried out the inventory control system linked.
Model utility content
In order to overcome the defect in above-mentioned background technology, the utility model provides the inventory control system with pump valve linkage function, connects valve and controls, detect the state of state with control pump of valve simultaneously by inventory control system.
For achieving the above object, the utility model proposes following technological scheme: the inventory control system with pump valve linkage function, comprise overall control device, valve and pump, wherein overall control device connects valve and the control of opening valve or cutting out by relay, and described valve is provided with position limit switch, and described position limit switch connects relay, and connecting by a road signal of relay the feedback that overall control device carries out valve state, another road signal connects the start stop switch of described pump.
Described position limit switch triggers when valve is opened completely.
Compared with prior art; the inventory control system of what the utility model disclosed have pump valve linkage function; there is following usefulness: inventory control system is connected valve; the effective control to valve can be realized; on the complete opening point of valve, increase position limit switch and be connected to pump by relay simultaneously, make valve open rear trigger relay completely thus open pump, pump being only had and just can open when valve is opened completely; otherwise be in closed condition, thus protect conveyance conduit.
Accompanying drawing explanation
Fig. 1 is block schematic illustration of the present utility model.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, clear, complete description is carried out to the technological scheme of the utility model embodiment.
As shown in Figure 1, the inventory control system of what the utility model disclosed have pump valve linkage function, comprises the valve 1 be arranged on conveyance conduit, connects the overall control device 2 of valve 1 and be positioned at the pump 3 of blowdown factory.
Particularly, described overall control device 2 connects valve 1 for the unlatching of control valve or cut out by relay 5, described valve 1 is provided with position limit switch 4, to only have when valve 1 is opened completely and just trigger position limit switch 4 and close, described position limit switch 4 connects relay 5, and connect overall control device 2 by a road of relay 5, the opening state of valve is fed back to overall control device 2 thus realizes the detection to valve state, another road of described relay 5 connects the start stop switch 6 of pump 3, after valve 1 is opened completely, trigger position limit switch 4 to close, thus trigger enable switch startup, open pump 3.
Inventory control system described in the utility model; not only valve and pump are controlled separately, but valve and pump are carried out coordinated signals, can by the state of valve state control pump; thus avoid in conveyance conduit and occur, into having more few phenomenon, protecting conveyance conduit.
Technology contents of the present utility model and technical characteristics have disclosed as above; but those of ordinary skill in the art still may do all replacement and the modification that do not deviate from the utility model spirit based on announcement of the present utility model; therefore; the utility model protection domain should be not limited to the content that embodiment discloses; and various do not deviate from replacement of the present utility model and modification should be comprised, and contained by present patent application claim.
Claims (2)
1. there is the inventory control system of pump valve linkage function, it is characterized in that: comprise overall control device, valve and pump, wherein overall control device connects valve and the control of opening valve or cutting out by relay, described valve is provided with position limit switch, described position limit switch connects relay, and connects by a road signal of relay the feedback that overall control device carries out valve state, and another road signal connects the start stop switch of described pump.
2. the inventory control system with pump valve linkage function according to claim 1, is characterized in that: described position limit switch triggers when valve is opened completely.
