Utility model content
Technical problem to be solved in the utility model is for shortcomings and deficiencies of the prior art, provides a kind of full-automatic and the steam in pipeline can be drained to clean drainage arrangement control circuit, to address the above problem.
The technical matters that the utility model solves can realize by the following technical solutions:
Oil-water separator timing water drainage device control circuit, comprise that one is serially connected on the main line of control circuit in order to control the master switch of this control circuit break-make, it is characterized in that, comprise very first time relay, second time relay and solenoid valve, described very first time relay has an on-delay normally opened contact, described second time relay has normally opened contact and a power cut off delay normally closed contact in a flash, described very first time relay is attempted by described main line two ends after being connected in series with power cut off delay normally closed contact, described second time relay is attempted by described main line two ends after being connected in series with on-delay normally opened contact, described moment, normally opened contact was attempted by described main line two ends after being connected in series with described solenoid valve.
In a kind of preferred embodiment of the present utility model, described moment normally opened contact two ends and be connected to a manual drainage switch of manually controlling solenoid valve draining.
In a kind of preferred embodiment of the present utility model, the on-delay duration of described very first time relay is 30 minutes, and the power cut off delay duration of described second time relay is 20 seconds.
Principle of work of the present utility model is as follows:
In the time of closed master switch, very first time relay obtains on-delay normally opened contact closure after electric and time delay a period of time, this period of time interval is the time interval of solenoid valve draining, when after on-delay normally opened contact closure, second time relay obtain electric rear moment normally opened contact closure and power cut off delay normally closed contact disconnect, now solenoid valve obtains electric work and carries out draining, and closed after power cut off delay normally closed contact time delay a period of time, this period of time interval is the time of solenoid valve draining, when very first time relay after power cut off delay normally closed contact closure obtains electric, on-delay normally opened contact disconnects, the second time relay dead electricity, moment normally opened contact disconnection, now solenoid valve dead electricity stops draining, then repeat above-mentioned steps always, make solenoid valve Auto-drainage a period of time behind interval at set intervals, realize timing drainage function.
Owing to having adopted technical scheme as above, the utility model is by the draining that is used in conjunction with to control solenoid valve of two time relays, very first time relay can be controlled the time interval of solenoid valve draining, second time relay can be controlled the time of solenoid valve draining, realize the Full automatic timing draining of solenoid valve, and when the on-delay duration of very first time relay is 30 minutes, when the power cut off delay duration of second time relay is 20 seconds, drainage effect of the present utility model is better, both saved manual operation resource, steam in pipeline can be drained only again.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the electrical schematic diagram of the utility model oil-water separator timing water drainage device control circuit.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Figure 1, oil-water separator timing water drainage device control circuit comprises master switch SB1, very first time relay 1JS, the second time relay 2JS and solenoid valve YV, master switch SB1 is serially connected on the main line of main line of control circuit, to control the break-make of this control circuit.
Very first time relay 1JS has an on-delay normally opened contact 1JS-1, the second time relay 2JS has normally opened contact 2JS-1 and a power cut off delay normally closed contact 2JS-2 in a flash, two ends after very first time relay 1JS is connected in series with power cut off delay normally closed contact 2JS-2 are attempted by respectively on the live wire L and zero line N of main line, two ends after the second time relay 2JS is connected in series with on-delay normally opened contact on-delay normally opened contact 1JS-1 are attempted by respectively on the live wire L and zero line N of main line, two ends after moment normally opened contact 2JS-1 is connected in series with solenoid valve YV are attempted by respectively on the live wire L and zero line N of main line.
Principle of work of the present utility model is as follows:
In the time of closed master switch SB1, very first time relay 1JS obtains electric and time delay on-delay normally opened contact 1JS-1 closure after 30 minutes, this period of 30 minutes time interval is the time interval of solenoid valve YV draining, when after on-delay normally opened contact 1JS-1 closure, the second time relay 2JS obtain electric rear moment normally opened contact 2JS-1 closure and power cut off delay normally closed contact 2JS-2 disconnect, now solenoid valve YV obtains electric work and carries out draining, and power cut off delay normally closed contact 2JS-2 time delay is closed after 30 seconds, this period of 30 seconds time interval is the time of solenoid valve YV draining, when very first time relay 1JS after power cut off delay normally closed contact 2JS-2 closure obtains electric, on-delay normally opened contact 1JS-1 disconnects, the second time relay 2JS dead electricity, moment normally opened contact 2JS-1 disconnects, now solenoid valve YV dead electricity stops draining, then repeat above-mentioned steps always, make solenoid valve YV Auto-drainage 20 seconds behind 30 minutes intervals, realize timing drainage function, and the on-delay duration of very first time relay 1JS is 30 minutes, the power cut off delay duration of the second time relay 2JS is 20 seconds, this two times can change according to specific needs, just solenoid valve YV Auto-drainage drainage effect of 20 seconds behind 30 minutes intervals is better, realize the Full automatic timing draining of solenoid valve YV, both saved manual operation resource, steam in pipeline can be drained only again.
For handled easily, at the two ends of moment normally opened contact 2JS-1 and be connected to a manual drainage switch S B2 who manually controls solenoid valve draining, only need closed manual drainage switch S B2, can make solenoid valve YV obtain electric work, realize and manually control solenoid valve YV draining.
