The utility model can be used for only providing the temperature controller of valve opening signal output, realizes driving valve, close valve control electric-controlled ball valve.Therefore, the electric-controlled ball valve that provides of the utility model has use value widely.Simultaneously, because the minimizing of connecting line can reduce wiring cost.
Description of drawings
Fig. 1 is the control circuit figure of electric-controlled ball valve in the prior art;
Fig. 2 is the utility model first embodiment's electric-controlled ball valve control circuit figure.
Embodiment
Please, be the utility model first embodiment's electric-controlled ball valve control circuit figure referring to Fig. 2.
In this control circuit, comprise temperature controller 3 and electric-controlled ball valve 4.
What described temperature controller 3 adopted is the temperature controller that has only valve opening signal output, the output line of this temperature controller comprises live wire 31, valve opening signal line 32, zero line 33, described live wire 31 connects the live wire L of civil power 220V, and described zero line 33 connects civil power zero line N.
Described electric-controlled ball valve 4 is different with electric-controlled ball valve of the prior art, and this electric-controlled ball valve 4 also has relay J except that having final controlling element and valve body (figure do not show), also illustrates among the figure on the control wiring of this electric-controlled ball valve and is in series with position limit switch S1 and position limit switch S2.Described final controlling element is motor M ', and having just changes line 41, reversed line 42, zero line 43, the described terminal that line 41 connects position limit switch S1, the terminal of described reversed line 42 connection position limit switch S2, the zero line N of described zero line 43 connection civil power 220V of just changeing.Rotating cam (figure does not show) is installed on the main shaft of this motor M ', and this rotating cam is used for pressing position limit switch S1 and position limit switch S2, realizes the control to the angle of swing of motor M '.
Described relay J comprises coil JS, normally-closed contact K1, normally opened contact K2, common port K.Described coil JS one end connects the zero line N of civil power 220V, and the other end connects the valve opening signal line 32 of temperature controller as control end.Described common port K connects the live wire L of electric main 220V, and described normally-closed contact K1 connects with the terminal that is not connected with the reverse signal line of motor M ' of position limit switch S2; Described normally-closed contact K2 connects with the terminal that is not connected with the positive rotaring signal line of motor M ' of position limit switch S1.When described position limit switch S1 does not open as yet fully at electric-controlled ball valve, be in closed state, after electric-controlled ball valve was opened fully, the trip switch was subjected to described rotating cam pressing and disconnects; Described position limit switch S2 is in closed state when electric-controlled ball valve is not closed fully as yet, after the complete closure of electric-controlled ball valve, the trip switch is subjected to described rotating cam pressing and disconnects.
During work, when temperature controller 3 according to temperature detection result, judge when needing the current circulation, conducting between the live wire 31 of temperature controller 3 and the valve opening signal line 32, described valve opening signal line 32 obtains the 220V civil power, temperature controller 3 output valve opening signals, the relay coil JS of described electric-controlled ball valve 4 gets electronic work, the normally opened contact K2 of relay is communicated with the common port K of relay, at this moment, if motor M ' does not rotate to out valve position as yet, then position limit switch S1 is in closed state, therefore, the just commentaries on classics line 41 of described motor M ' gets electric, and this motor M ' just changes.When motor M ' was just forwarding valve body to and opens fully, the described position limit switch S1 of the rotating cam pressing on the motor main shaft disconnected position limit switch S1, and described motor M ' outage is stopped the rotation.On the contrary, when temperature controller 3 according to temperature detection result, when judge to need disconnecting current, described valve opening signal line 32 must not electricity, therefore, relay coil JS also must not electricity, relay is failure to actuate, described relay normally-closed contact K1 is communicated with relay common port K.At this moment, if when motor does not rotate to the fully closed position of valve body as yet, described position limit switch S2 will be in closed state, the reversed line 42 of motor M ' electric, motor M ' counterrotating, closed valve body; When motor rotated to the state of the complete closure of valve body, described position limit switch S2 was installed in the rotating cam pressing on the motor main shaft and disconnects, reversed line 42 outages of described motor M ', and motor M ' stops the rotation.Above-mentioned working procedure makes described electric-controlled ball valve only need temperature controller output valve opening signal, the action of driving valve, pass valve that just can be correct.
The foregoing description is preferred embodiment of the present utility model.Core concept of the present utility model is, by the expansion of gate-controlled switch, makes the temperature controller that only sends a valve opening signal can realize the control that electric-controlled ball valve is realized driving valve, closed the valve two states.In fact, can also adopt the element of some other forms to realize technique scheme in this electric-controlled ball valve.For example, described motor can adopt stepping motor.Because the problem of stall heating can not take place stepping motor, therefore, when using stepping motor, can not use position limit switch to detect motor and whether be rotated in place, and the mechanical resistance that produces when being rotated in place by valve body stops stepping motor to continue rotation.Same, the relay in the present embodiment also can adopt the gate-controlled switch of forms such as solid-state relay, controllable silicon to replace, and at the gate-controlled switch form of concrete employing, the physical circuit in the described electric-controlled ball valve is different.But its final purpose all is the form by normally opened contact, normally-closed contact, realizes utilizing a valve opening signal of temperature controller, realizes the control to the two kinds of working staties of just changeing, reverse of motor.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
