Abstract
The utility model discloses a kind of without negative pressure flow-control module, comprise input end, output terminal and auxiliary reclay solenoid, metal shell, line bank, described input end is corresponding in turn to output terminal and is communicated with, on the circuit that described auxiliary reclay solenoid is connected to input end, output terminal is communicated with, described line bank is positioned on metal shell.This module electromagnetic relay and there is independent controlling functions accessory combination to a stainless steel box to install more easily and being separated of function.
Description
Technical field
The utility model relates to the application of flow-control module, especially a kind of without negative pressure flow-control module.
Background technology
Existing without negative pressure flow-control module in often there is the placement that one-piece construction is at random, all parts can not be orderly.And negative pressure flow-control module traditionally in use not only inaccurate to flow control, produce larger error, and overall result of use is not good, makes troubles in maintenance, periodic maintenance yet.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of without negative pressure flow-control module.
For realizing this technical purpose, scheme of the present utility model is: a kind of without negative pressure flow-control module, comprise input end, output terminal and auxiliary reclay solenoid, metal shell, line bank, described input end is corresponding in turn to output terminal and is communicated with, on the circuit that described auxiliary reclay solenoid is connected to input end, output terminal is communicated with, described line bank is positioned on metal shell.
As preferably, described metal shell adopts stainless steel to design and produce.
As preferably, described line bank has two, lays respectively at input end and output terminal.
This module electromagnetic relay and there is independent controlling functions accessory combination to a stainless steel box to install more easily and being separated of function.
Accompanying drawing explanation
Fig. 1 is the circuit module figure controlling output without vacuum flow amount controller.
Embodiment
Below in conjunction with accompanying drawing basis and specific embodiment, the utility model is described in further details.
As shown in Figure 1, the one of the utility model embodiment is without negative pressure flow-control module, its structure mainly comprises input end 1,2,3, output terminal 4,5,6 and auxiliary reclay solenoid 7, metal shell 8, line bank 9, described input end 1,2,3 is corresponding in turn to output terminal 4,5,6 and is communicated with, on the circuit that described auxiliary reclay solenoid 7 is connected to input end 3, output terminal 6 is communicated with, described line bank 9 is positioned on metal shell 8.
As preferably, described auxiliary reclay solenoid 7 and there is independent controlling functions accessory combination to the box of a metal shell to install more easily and being separated of function.
As preferably, described metal shell 8 adopts stainless steel to design and produce.
As preferably, described line bank 9 has two, lays respectively at input end and output terminal.
This module in actual applications, one, when PLC does not export electric signal to module, K1 coil is energising no, power supply 1,2 inputs, and it is 5,6 (220V) that equipment exports.Two, when PLC has electric signal to export (220V live wire), entering a 3 and 2 formation loop K1 auxiliary reclay solenoid obtains electric, coil adhesive K1 often make war (a) close, 1 and 4 connect, the normally closed point (b) of KA disconnects, 1 and 6 disconnect, and output point is exactly 4 and 5, complete the output of output point from 5 and 6 to 4 and 5 and transform.Three, when PLC output signal disconnects, equipment recovers again the state of.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
Claims (2)
1. one kind without negative pressure flow-control module, comprise input end, output terminal and auxiliary reclay solenoid, metal shell, line bank, it is characterized in that: described input end is corresponding in turn to output terminal and is communicated with, on the circuit that described auxiliary reclay solenoid is connected to input end, output terminal is communicated with, described line bank is positioned on metal shell.
2. according to claim 1 a kind of without negative pressure flow-control module, it is characterized in that: described line bank has two, lay respectively at input end and output terminal.
