Abstract
The invention discloses a water leakage detector, mainly comprising a shell, a signal collecting device and a switch valve. In the invention, a piston of the water leakage detector is provided with a magnet, and a solenoid valve is arranged outside a water inlet horizontal pipe cavity of the shell and is opposite to the magnet sheathed in the piston, so the solenoid valve can sensitively detect the position change of the magnet in the piston and make a sensitive response to small change of water flow; and once the water pressure in a water pipe changes, the piston can move so as to drive the magnet to move, so the solenoid valve can transmit the change of an electrical signal caused by movement of the magnet to a warning device to give out the alarm. In addition, the water leakage detector is provided with the switch valve composed of a piston post, a waterway nut, a reset handle and the like; and a pathway of the water leakage pipe can be turned on or cut off so as to turn on or block up water flow by means of combination or separation of the solenoid valve and the reset handle on the switch valve,, thereby effectively avoiding further water leakage phenomenon.
Description
Technical field
The present invention relates to a kind of current checkout equipment, particularly relate to a kind of water leak detectors.
Background technology
In water lines, if leak or during the spilling water phenomenon,, possibly cause indoor serious ponding or the equipment can't normal operation if can't in time find or detect, so that device damage, the apprentice increases because of disturbing.And in the modern times of paying much attention to each item resource, the serious problems of waste water resource beyond doubt of leaking.Cause the two kinds of forms of having leaked of house and property loss, a kind of is small or a large amount of the leaking that causes because of reasons such as water pipe are aging, and another kind is that the people is leaking of causing, as forgets and close water swivel or water works fault or misoperation etc.No matter any leaking is the destruction that prevents that it from causing, and it is necessary that the timely detection of leaking and reporting to the police starts.There are several kinds in the prior art as the method for leaking that often detects in the buildings.For example, can leak through the sound wave shock detection of measuring the water pipe conduction.Also have, the utilization ultrasound examination is leaked.Yet said method all needs main equipment, and can only detect a large amount of leaking, and sensitivity is lower.
Summary of the invention
But the object of the present invention is to provide a kind of detection at any time water pipe simple in structure leak situation, can cut off the water leak detectors of current automatically.
For realizing above-mentioned purpose, technical solution of the present invention is:
A kind of water leak detectors mainly is made up of housing and signal pickup assembly; This housing is a tee pipe fitting; Described signal pickup assembly comprises piston, magnet and solenoid valve; Described piston is movably set in the water inlet end tube chamber of housing; This piston and intraluminal gap constitute the water channel of circulation; Magnet is located on the piston, and described solenoid valve is installed in the housing water inlet tube chamber outside and relative with magnet in the piston, so that survey the variation of magnet positions.
Described signal pickup assembly comprises back-moving spring, piston, magnet, water supply connector, solenoid valve; Described back-moving spring, piston are nested with in regular turn in the horizontal tube chamber of the water inlet of housing; The two ends of back-moving spring lean on the intraluminal next door of the level of housing the inner face with piston respectively, and water supply connector is screwed onto the port of the horizontal tube chamber of this water inlet; Described piston is that the middle part is the member that right cylinder, periphery have a plurality of flanks; Gap between a plurality of flanks of piston constitutes the water channel of circulation; The middle part inner at right cylinder offers a counterbore; The magnet activity is nested with in the counterbore of piston, the activity of right cylinder outer end be located on the water supply connector necking segment and with the little clearance fit of this necking segment inner chamber.
It also comprises a switch valve, and this switch valve mainly is made up of pad, piston boit, spring, water channel nut, the handle that resets; Described pad, piston boit, spring are nested with in regular turn in the vertical tube chamber of housing; The water channel nut is screwed onto the port of vertical tube chamber; Described piston boit is the ladder right cylinder, and small cylinder is a pulling shaft, and it is hinged with the handle that resets that this pulling shaft upwards passes the water channel nut; Spring housing is connected on the pulling shaft; The two ends of spring lean on the cascaded surface of piston boit the inner top surface with the water channel nut respectively, form the pressure of a downward roof pressure, press to the mouth that combines of the vertical tube chamber of housing and horizontal tube chamber with being nested with pad in the piston boit lower end.
It also comprises water out adapter, and this water out adapter is screwed onto the port of water outlet tube chamber.
It also comprises a warning device, and this warning device mainly is made up of shell, electromagnetic inductor; Described shell is wrapped in the outside of housing, and solenoid valve and electromagnetic inductor are installed in the enclosure, on shell, are provided with cell containing cavity.
After adopting such scheme; Because the present invention is designed with signal pickup assembly; In the piston of this signal pickup assembly magnet is installed; And solenoid valve is installed in the horizontal tube chamber of the housing water inlet outside and relative with the magnet that is nested with in piston, the variation of the detection piston internal magnet position that solenoid valve can be sensitive can be made sensitive reaction to the discharge subtle change.In case the hydraulic pressure in the water pipe changes, piston will move, and drives magnet and moves, and solenoid valve just can move the change in electric of being brought with magnet and send warning device to, gives the alarm.Therefore, no matter be because water pipe aging cause leak naturally or the people is leaking of causing, as forget turn off the tap, heating equipment fault, misoperation, he warning device all can sends alerting signal.In addition; The present invention is provided with the switch valve of being made up of piston boit, water channel nut, the handle that resets etc., can be through the adhesive or the disengaging of the handle that resets on solenoid valve and the switch valve, but conducting or the cut-out water pipe channel that leaks just; Conducting or blocking-up current can effectively prevent the further generation of drainage.
Below in conjunction with accompanying drawing and specific embodiment the present invention is further described.
