Description
Technical Field
The utility model relates to a linkage technical field, concretely relates to aggregate unit of control fan and motorised valve.
Background
In many buildings, a fan (or an exhaust fan) is arranged in a room for dehumidification and ventilation of the room environment, an electric valve is arranged at the connection between the fan and the outside of the room to realize the effects of fan operation and indoor and outdoor isolation control, and the control of the electric valve generally requires that the electric valve opens the fan to start and stops and the electric valve closes. The control requirements of the low-power blower and the electric valve can be started or stopped simultaneously.
Based on the above requirements, a start/stop control button is generally used to cooperate with a contactor, a thermal relay and other control protection devices to realize linkage control (as shown in fig. 1). Although the control is a common linkage relation in an electrical control system, the power of the exhaust fans arranged in a plurality of rooms with small areas is low, and the exhaust fans are mostly-220V exhaust fans, if the control mode is adopted, the control mode is too complex and inconvenient to use and operate, and a special control box for the fans needs to be additionally arranged, so that the engineering investment is increased.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a linkage of control fan and motorised valve need not additionally to set up the special control box of fan, can realize the same start-stop linkage control of fan and motorised valve.
The technical scheme of the utility model is that: a linkage for controlling a blower and an electrically operated valve, comprising: the double control switch, the fan and the electric valve;
one end of the double-control switch is electrically connected with a power supply live wire end, and the other end of the double-control switch is provided with two contacts which are a normally closed contact and a normally open contact respectively, wherein the normally closed contact of the double-control switch is electrically connected with the live wire end of the fan;
one end of the electric valve is electrically connected with the zero line end of the fan, and the other end of the electric valve is divided into an electric valve opening valve and an electric valve closing valve;
the electric valve opening valve is electrically connected with a fire wire end of the fan;
and the electric valve closing valve is electrically connected with the normally open contact of the double control switch.
Preferably, the linkage is arranged on a power supply circuit of the lamp in the room.
Has the advantages that:
(1) the utility model provides a linkage simple structure need not additionally to set up the special control box of fan, can realize that the fan is with opening with stopping of motorised valve, uses the operation succinct, and the maintenance is convenient, has effectively reduced engineering cost.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings by way of examples.
In this embodiment, an AC220V exhaust fan (hereinafter referred to as a fan) is taken as an example, and the exhaust fan may be the same as the exhaust fan.
The embodiment provides a linkage device for controlling a fan and an electric valve, a special control box for the fan does not need to be additionally arranged, and the linkage control of the fan and the electric valve on the same start and stop can be realized.
As shown in fig. 2 and 3, the single-control switch 1 is used for controlling on/off of lamps in a room, and has the circuit connection relationship: the lamp is respectively connected with the single-control switch 1 and the zero line end of the commercial power supply, and the single-control switch 1 is connected with the fire line end of the commercial power supply to form a power supply loop; the voltage of the mains supply is 220V, when the single-control switch 1 is closed, the path where the lamp is located is switched on, and the lamp is lightened.
The linkage device is arranged on a power supply loop of the lamp and comprises a double-control switch 2, a fan 6 and an electric valve 5; the zero line end of the fan 6 is electrically connected with the zero line end of the lamp power supply loop, one end of the double-control switch 2 is electrically connected with the fire line end of the lamp power supply loop, and the other end of the double-control switch comprises a normally closed contact and a normally open contact which respectively correspond to a '1' position and a '0' position; the normally closed contact of the double-control switch 2 is electrically connected with the fire wire end of the fan 6; the zero line end of the fan 6 is electrically connected with one end of the electric valve 5, the other end of the electric valve 5 is provided with an electric valve opening valve 3 and an electric valve closing valve 4, the electric valve opening valve 3 of the electric valve 5 is electrically connected with the fire line end of the fan 6, the electric valve closing valve 4 is electrically connected with a normally open contact of the double control switch 2, and when the circuit where the electric valve opening valve 3 is located is electrified, the electric valve 5 is in an open state; when the line of the electric valve closing valve 4 is electrified, the electric valve 5 is in a closed state.
Specifically, the method comprises the following steps: when the normally closed contact of the double-control switch 2 is closed, the circuit where the fan 6 is located is communicated, the fan is started, at the moment, the circuit where the electric valve opening valve 3 is located is communicated, and the electric valve 5 is opened; when the normally open contact of the double control switch 2 is closed, the fan 6 is stopped, at this time, the electric circuit of the electric valve closing valve 4 is connected, and the electric valve 5 is closed.
In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
