Description
Technical field:
The present invention relates to a kind of water pipe to leak and automatically shut down protective gear, be particularly useful for that Household tap water pipe ruptures, tap damages or automatic shutoff protection under unmanned state during the long-time flowing water of tap water.
Background technique:
At present, the tap water used in life is all supplied water by water tower water-feeding or electric pump respectively, it is all generally control water source by an artificial total valve that this water facilities enters every family, if often there is the long-time overflow of tap water in these situations such as water pipe fracture, water tap damage occurring when nobody, forgets closed tap, chamber pot leaks, not only cause the waste of great water resources, also cause unnecessary economic loss to family simultaneously.
Summary of the invention:
In order to overcome above-mentioned deficiency; the invention provides a kind of water pipe to leak and automatically shut down protective gear; when unmanned at home; when long-time overflow appears in tap water, this protective gear can automatically shut down water source; employing the present invention is easy for installation; save water resources, eliminate the trouble and worry in life, safe and reliable.
The technical solution adopted for the present invention to solve the technical problems is: a kind of water pipe leaks and automatically shuts down protective gear, comprise electromagnetic water valve, water switch, manual aqueduct valve, it is characterized in that: also comprise electric control system, described electric-controlled system is arranged in a chamber, by very first time relay, second time relay, alarm, resume water supply button, closedown water supply button forms, the conducting contact of water switch is serially connected with in the field circuit of described very first time relay, be serially connected with in the field circuit of the second described time relay resume water supply button and very first time relay pick up front contact and second time relay in parallel with its front contact two ends pick up front contact, be connected with the light of alarm and acoustics circuit while of after two contacts, the front contact of very first time relay energized is serially connected with in acoustics circuit, The electric-controlled system is connected with power supply by wire, the contact of described water switch is connected with electric-controlled system by electric wire, the control electric wire that electric lead and the electric-controlled system of described electromagnetic water valve are drawn is connected, control the contact and the shutoff water supply button that are serially connected with second time relay in the circuit of electric wire, described electromagnetic water valve one end is connected with water switch, described manual aqueduct valve connects the two ends be installed in parallel at electromagnetic water valve and water switch by water pipe.
Reasonable in design of the present invention, rupture at water pipe, tap damages or people forgets to close when water tap occurs that tap water leaks for a long time all can automatically shut down water source, very first time relay in control system is worked hard in glove with time delay through the conducting contact of water switch and is picked up circuit, the time delay that the front contact that very first time relay picks up through time delay has connected second time relay picks up circuit, the circuit simultaneously having connected again alarm makes it send light and audible alarm, the contact that second time relay picks up through time delay or the field circuit disconnecting electromagnetic water valve make it pick up or fall to control to close water source, after water pipe is protected automatically, very first time relay loss of excitation falls cut-out audible alarm, when resume water supply field circuit that namely button cut off second time relay of pressing makes it fall to cut off or connected the field circuit of electromagnetic water valve, electromagnetic water valve is picked up or falls again to open water source, manual aqueduct valve leaks to automatically shut down to open protective gear breaks down at this water pipe and can ensure just commonly using water, when waterpipe facility maintenance and installation needs to close water valve, can press closedown water supply button can make electromagnetic water valve pick up or fall closedown water valve.The present invention is applied widely, the power supply of electromagnetic water valve and the time relay all can adopt the different size such as ac380v, ac220v or dc220v, dc24v, dc12v, under water pump or the different water supply standard of two kinds, water tower, can by change the time relay pick up or bottom contact control electromagnetic water valve pick up or fall open and close water valve, to meet usage requirement.
The two kinds of different modes that pick up or fall of electromagnetic water valve are why adopted to open or turn off aqueduct valve, consider when electric pump water supply standard is to provide water source by voltage driven water pump, if there is no electricity just without water source, therefore the full state of electromagnetic water valve is adopted to fetch boiling water tube valve, the state that picks up turns off aqueduct valve, no during electricity, water pipe is not in guard mode naturally, and key does not consume the energy when normal use, only after water pipe is protected automatically, just consumes the energy; When by water tower water-feeding; have a power failure and not necessarily cut off the water, therefore adopt the state that picks up of electromagnetic water valve to fetch boiling water tube valve, full state turns off aqueduct valve; just automatically shut down aqueduct valve once power failure, guarantee nobody automatic shutoff protective gear can be safe and reliable when leaking use of tap water.
Beneficial effect of the present invention is:
The present invention has the following advantages compared with existing technology:
1, when unmanned, tap water occurs leaking for a long time to have and can automatically shut down water source, saves water resources, eliminates the trouble and worry in life, safe and reliable.
2 the present invention are easy for installation, and protective gear has before cutting off the water supply reports to the police and forecasts prompt facility in advance, and having the situation of people can close water-stop valve earlier, reducing water resource waste, audible alarm is at once closed after automatic safety device cuts out water source, reduces the consumption of power supply.
3, the present invention in case of a fault, just can ensure normal water supply by the manual water tube valve opened on water pipe for subsequent use.
4, the present invention just can be resumed water supply fast by the pressing button that resumes water supply, and pressing is closed water supply button and just can conveniently be cut off the water supply, and is convenient to waterpipe erection of equipment and keeps in repair.
5, reasonable in design of the present invention, is convenient to processing and fabricating, and protective gear consume electric power is low, for the not consume electric power substantially in normal state of the protective gear in electric pump water supply standard.
