Description
Technical field
The utility model relates to technical field of electromechanical control, more particularly to a kind of air-valve and blower chain control module.
Background technique
By taking office building as an example, fresh air system must be arranged in setting central air-conditioning.Fresh air handling units will be outdoor new by air hose
Wind is sent into indoor, guarantee room air circulation.At northern frore area, winter, when Fresh air handling units are closed, outdoor cold air
Can with the wind pipe enter the room, reduce indoor heating effect, and can by the frost crack pipe of neighbouring aqueous medium, cause interior decoration,
Public utility damage, property loss.
Therefore in current engineering design, new air-valve often is set in air hose and outdoor connectivity part, it, will be new in the starting of new blower
Air-valve open, guarantee send fresh air duct unimpeded, when fresh air organ closes, new air-valve need to be closed, prevent cool ambient air not into
Enter interior, guarantee indoor heating effect, it is freezing by severe cold to be also prevented from indoor water medium pipeline.
Utility model content
The purpose of this utility model is and to provide a kind of air-valve and blower connects for technological deficiency existing in the prior art

Motor operation limit switch includes rotating in the forward direction circuit normally-closed contact and reversely rotating circuit normally-closed contact, and the forward direction is revolved
Go back to road normally-closed contact and reversely rotate circuit normally-closed contact respectively with the normally opened contact of intermediate relay, normally-closed contact be connected
It connects, the normally opened contact of intermediate relay, is connected after normally-closed contact is in parallel with breaker, the Electric air valve motor operation limit
The earthing switch of bit switch is connect with zero curve.
The breaker connects fastp-acting fuse, and the fastp-acting fuse is connect with firewire.
Compared with prior art, the utility model has the beneficial effects that
The content of the utility model, is with easy-to-use mode, realize new air-valve and blower with open, with closing, both
Room ventilation effect when ensure that fan operation, but adverse circumstances when can prevent blower from closing outside room influence room temperature.
Detailed description of the invention
Fig. 1 show the air-valve of the utility model and the structural schematic diagram of blower chain control module.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
As shown in Figure 1, the air-valve of the utility model includes: with blower chain control module
The electric current inductive switch K being mounted on blower current supply circuit, Electric air valve motor operation limit switch QS1 ', centre
Relay KA and circuit breaker Q A1, the breaker are connect with electric current inductive switch, the electric current inductive switch and intermediate relay
In parallel with Electric air valve motor operation limit switch after the series connection of device coil, the Electric air valve motor operation limit switch includes just
To Rotary Loop normally-closed contact and circuit normally-closed contact is reversely rotated, the described circuit normally-closed contact and reversed of rotating in the forward direction
Respectively with the normally opened contact of intermediate relay, normally-closed contact is connected Rotary Loop normally-closed contact, the normally opened touching of intermediate relay
Point, normally-closed contact are connected with breaker, the ground terminal (N-terminal) and zero of the Electric air valve motor operation limit switch
Line N connection, the breaker connect fastp-acting fuse FU, and the fastp-acting fuse FU is connect with firewire L1.
It should be noted that the Electric air valve motor operation limit switch is the composition portion of Electric air valve in the present invention
Point, it is directly connect with Electric air valve, by the connection in positive and negative rotation circuit, control air-valve motor positive and inverse is realized, to drive institute
The air-valve stated executes closing motion.
In the utility model, the electric current inductive switch is installed on the distribution major loop of blower, when Fresh air handling units are run,
The electric current for necessarily leading to a certain size in distribution major loop, by deliberate action current value, when detecting that loop current reaches
After this current value, inductive switch normally opened contact closure, the input signal that this contact is controlled as air-valve.
It is shown in Figure 1, when Fresh air handling units operation, electric current inductive switch normally opened contact K closure, intermediate relay KA line
Circle is powered, so that intermediate relay normally opened contact is closed, normally-closed contact closure, Electric air valve rotates in the forward direction circuit and powers on,
Air-valve motor rotates forward, and driving air-valve executes breakdown action.
Conversely, electric current inductive switch detects major loop no current, that is, judge that Fresh air handling units have stopped working, electric current induction
Switch output normally opened contact K closure, intermediate relay KA normally opened contact disconnect, and normally-closed contact closure, Electric air valve reversely rotates
Circuit is connected, and air-valve motor reversion, driving air-valve executes closing motion.
The working principle of the utility model is as follows:
Distribution main circuit current is detected, it is whether in running order that unit is judged by main circuit current, then pass through centre
Relay logic realizes the action control to air-valve.
The utility model does not pass through manual intervention, with simple, effective control mode, realization to air-valve it is same open,
With connection lock control, it ensure that central ventilation system works normally, when in turn avoiding fresh air system closing, external environment is to interior
Caused by baneful influence.
Inductive switch is arranged by installing electric current inductive switch in distribution box Fresh air handling units main distribution circuit in the utility model
The current value of movement, works as fan operation, and main circuit current reaches setting value, electric current inductive switch output control signal.Pass through sense
The control signal of the output of inductive switch realizes the judgement of fan operation, halted state, then real with intermediate relay control logic
Now the unlatching of Electric air valve, closing are controlled.
The utility model is characterized in that the input signal by detection main circuit current as Fresh air handling units operating status,
It realizes that unlatching, closing to Electric air valve control by the conversion of intermediate relay contact again, solves Electric air valve and new blower
The same of group opens, with connection lock control problem.
The utility model solves the problems, such as the chain control of new air-valve and blower, is realized by current signal to the chain of air-valve
Control, had both avoided complicated control circuit, had reduced costs, and realized and open, the same of air-valve with connection lock control.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
