Abstract
The utility model discloses a 220V electric valve DCS controlling means utilizes DC24V to open the valve relay, DC24V closes the isolation that the valve relay realized direct current control and AC control, DCS control system output DC24V opens the valve relay, DC24V closes the coil of valve relay, auxiliary contact control AC220V electric valve controller realizes that DCS is long-range to the control of valve switching, effectively avoided the interference to other instrument signal, make the system more stable.
Description
Technical Field
The utility model relates to AC220V electric valve control directly relates to a 220V electric valve DCS controlling means.
Background
This type electrically operated valve can not directly realize DCS remote control, and the lug connection can cause the interference to DCS system instrument signal, influences DCS control system's stability.
SUMMERY OF THE UTILITY MODEL
The utility model discloses do not change the electric valve control originally in the operation, realize the DCS control of valve, avoid causing the interference to other instrument signals, practice thrift and reform transform the cost.
The purpose of the utility model is realized like this: a DCS control device of a 220V electric valve is provided with an AC220V electric valve controller, a DC24V valve opening relay, a DC24V valve closing relay and a DCS control system; the AC220V electric valve controller connecting terminal is respectively connected with the DC24V valve opening relay auxiliary contact and the DC24V valve closing relay auxiliary contact; and the DC24V valve opening relay coil and the DC24V valve closing relay coil are respectively connected with the DCS control system.
The utility model has the advantages that: the utility model discloses utilize DC24V to open valve relay, DC24V to close valve relay and realize direct current control and alternating current control's isolation, DCS control system output DC24V opens valve relay, DC24V closes the coil of valve relay, and auxiliary contact control AC220V electric valve controller realizes that DCS is long-range to the control of valve switching, has effectively avoided the interference to other instrument signals, makes the system more stable.
Drawings
Fig. 1 shows a schematic structural diagram of the present invention, and the present invention is further explained with reference to fig. 1.
Detailed Description
A DCS control device of a 220V electric valve comprises an AC220V electric valve controller 1, a DC24V valve opening relay 2, a DC24V valve closing relay 3 and a DCS control system 4; the connecting terminal of the AC220V electric valve controller 1 is respectively connected with the auxiliary contact of the DC24V valve opening relay 2 and the auxiliary contact of the DC24V valve closing relay 3; and a coil of the DC24V valve opening relay 2 and a coil of the DC24V valve closing relay 3 are respectively connected with the DCS control system 4.
The working principle is as follows:
in the production process, when the AC220V electric valve needs to be closed, the coil of the DC24 valve closing relay 3 is controlled to be electrified by the DCS control system 4, the auxiliary contact acts, the AC220V electric valve controller 1 is controlled to execute a valve closing command, and the AC220V electric valve is closed; when the AC220V electric valve needs to be opened, the coil of the DC24 valve opening relay 2 is controlled to be electrified by the DCS control system 4, the auxiliary contact acts, the AC220V electric valve controller 1 is controlled to execute a valve opening command, and the AC220V electric valve is opened. The utility model discloses utilize DC24V to open valve relay 2, DC24V to close valve relay 3 and realize direct current control and alternating current control's isolation, DCS control system 4 output DC24V opens valve relay 2, DC24V closes the coil of valve relay 3, and auxiliary contact control AC220V electrically operated valve controller 1 realizes the long-range control to the valve switching of DCS.
