The signal of the flow switch is received using the integrated programmable controller and the switch-off of the electromagnetic valve is controlled, therefore the structure of the circuit is simple, the circuit is conveniently used and the feasibility is strong.

Description

The anti-intellective protector of metalling run out

Technical field

The utility model relates to feed pipe water supply field, particularly, relates to a kind of anti-intellective protector of metalling run out.

Background technology

In the patent No. is in the patent document of CN200410050519.7; A kind of tap water running prevention intelligent controller is disclosed; Mainly be made up of microprocessor, timing circuit, latch, display circuit, pulse-generating circuit, address decoder, parallel interface, house dog, input keyboard and switching value output circuit, wherein microprocessor is a core devices, is connected with display circuit through latch; Through meter the water moral currency is carried out timing; When solution surpasses certain value in the continuous water of the family time (improper water), close water supply electromagnetic valve automatically, avoid metalling run out.But circuit is very complicated, and feasibility is poor.

The utility model content

The purpose of the utility model is, to the problems referred to above, proposes a kind of anti-intellective protector of metalling run out, with the advantage that realizes that circuit is simple, feasibility is strong.

For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:

A kind of anti-intellective protector of metalling run out; Comprise solenoid valve, flow switch and Programmable Logic Controller; The passage of said solenoid valve passage and flow switch links together; The input end of said flow switch and Programmable Logic Controller is electrically connected, and the output terminal and the solenoid valve of said Programmable Logic Controller are electrically connected.

Further, said solenoid valve is an open type.

Further, said solenoid valve adopts AC coil.

The technical scheme of the utility model adopts the signal of integrated Programmable Logic Controller reception flow switch, the closure of control electromagnetic valve, thus realize that circuit structure is simple, easy to use, the purpose that feasibility is strong.

Further feature of the utility model and advantage will be set forth in instructions subsequently, and, partly from instructions, become obvious, perhaps understand through implementing the utility model.The purpose of the utility model can realize through the structure that in the instructions of being write, claims and accompanying drawing, is particularly pointed out and obtain with other advantages.

Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description below.

Description of drawings

Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of instructions, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:

Fig. 1 is the structural representation of the said anti-intellective protector of metalling run out of the utility model;

Fig. 2 is the electrical connection diagram of the said anti-intellective protector of metalling run out of the utility model;

Fig. 3 is the workflow diagram of the said anti-intellective protector of metalling run out of the utility model.

In conjunction with accompanying drawing, Reference numeral is following among the utility model embodiment:

The 1-water delivering orifice; The 2-water inlet.

Embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.

Like Fig. 1, shown in Figure 2; The anti-intellective protector of metalling run out comprises solenoid valve, flow switch and Programmable Logic Controller; The passage of said solenoid valve passage and flow switch links together; The input end of flow switch and Programmable Logic Controller links together through lead, and the output terminal and the solenoid valve of Programmable Logic Controller link together through lead.Solenoid valve, flow switch, Programmable Logic Controller are installed on the water supply feed pipe successively.Flow switch sends the flow letter information of feed pipe to Programmable Logic Controller, and Programmable Logic Controller is according to the switch of this signal controlling solenoid valve.The water inlet of solenoid valve passage links to each other with user's water supply feed pipe, and the water delivering orifice of solenoid valve passage links to each other with the water inlet of flow switch passage,, the water delivering orifice of flow switch passage is connected with user's water pipe.The contact of flow switch exchanges the contact for often opening; The solenoid valve solenoid is an AC coil; One of which end and zero line (N) join; One output port of its other end and Programmable Logic Controller joins, and an end of the normally opened contact of flow switch and power firestreak (L) join, and the input port of the other end and Programmable Logic Controller joins.

The anti-intellective protector of metalling run out comprises that the solenoid valve engineering of specifically working is as shown in Figure 3:

1) when not having water, water does not flow in the feed pipe, and the normally opened contact of flow switch can be not closed, and Programmable Logic Controller detects the noble potential less than flow switch, does not just give the coil electricity of solenoid valve, and the solenoid valve of often opening is opened.

2) (the water time is less than timing time continuously when the normal water of user; Such as 5 minutes), the flow switch normally opened contact is closed, and Programmable Logic Controller detects " height " current potential that the flow switch closing of contact sends; Programmable Logic Controller gets into time status; Programmable Logic Controller still detects the state of flow switch during the timing, if the user at the appointed time (in 5 minutes) shut tap and stop water, this current potential that makes the detected flow switch of Programmable Logic Controller send again is " low "; Programmable Logic Controller still can not given the coil electricity of solenoid valve, and solenoid valve can not cut out.

3) when metalling run out or during the time overlength (such as above 5 minutes) of the continuous water of user, Programmable Logic Controller can be switched on to electromagnetic valve coil in the time of 5 minutes, and it is closed, and stops to supply water, and prevents the bigger loss of metalling run out.

4) will metal run out after reason finds and rectified and improved as the user, and power up for device again, repeat above process after resetting.

What should explain at last is: the above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
