Abstract

The utility model relates to a water leakage protective device for a water purifier. The water leakage protective device comprises a normally-open solenoid valve, a buzzer, a pressure switch, a tee joint and a reducing joint, and is characterized in that the normally-open solenoid valve is arranged between a water inlet of the water purifier and a tap water pipe; a water outlet of the water purifier is connected with a faucet by using the tee joint and the pressure switch; the normally-open solenoid valve is connected in series with a power supply at one end of the pressure switch, and the other end of the pressure switch is connected in series with a 220V power supply; the buzzer is arranged between the normally-open solenoid valve and the pressure switch; one end of the buzzer is connected with the normally-open solenoid valve and the pressure switch, and the other end of the buzzer is connected in series with the 220V power supply; and the reducing joint is arranged between the faucet and the tee joint, so that water flow is reduced by the reducing joint to ensure the pressure of the pressure switch. The water leakage protective device has the advantages that when water in the water purifier leaks, the pressure switch turns on the solenoid valve while cutting off a water source, sends a signal and is communicated with the buzzer to give an alarm, so that property loss and the waste of water resources are avoided to the maximum limit.

Description

The water purifier protector that leaks

Technical field

The utility model relates to a kind of water purifier protector that leaks, and belongs to the texture improvement technology of water purifier.

Background technology

Water purifier in the market comprises two kinds of filer element type water purifier and RO membrane reverse osmosis water purification machines.These two kinds of machines all are directly to be connected with tap water, and pressure is excessive to cause filter core cylinder seepage, pipe connecting in the machine to be easy to come off, leak because the tap water hydraulic instability can occur; Particularly the topping-up pump of RO membrane reverse osmosis water purification machine will be got to 7kg pressure usually and just can make the RO film extrude pure water, but the pipe connecting of water purification machine also is easy to come off, leak under the state of high pressure.When machine occurring and leaking, find when not having urgency and close that the water source will cause any property loss and the waste of water resources.

The principle of work of PS is that when system's internal pressure was lower than the nominal standard atmosphere pressure, video disc is instantaneous in the inductor block was moved; Through connecting guide rod pull switch contacting or disconnection, when the nominal value is reduced to or risen to pressure, the video disc instant reset; Switch automatically resets; Perhaps briefly be when by the measuring pressure overrate, the free end of elastic element produces displacement, directly the pull switch element; Change the on off state of switching element, reach the purpose of control through the variation of pressure.

If PS is combined with water purifier; Pressure when water purifier leaks in the PS is lower than the nominal safe pressure; The interior video disc of inductor block this moment sinks, and PS is connected the water purifier entering water electromagnetic valve is closed, and just can avoid the waste of property damage and water resources to greatest extent.

Summary of the invention

The purpose of the utility model is to provide a kind of water purifier protector that leaks.This water purifier protector that leaks has dependable performance, stable and sensitive characteristics.

The utility model is to realize through following technical proposals: a kind of water purifier protector that leaks, and it comprises normally open solenoid valve, hummer, PS, threeway and reducer union; It is characterized in that; Between water purifier water-in and tap water water pipe, normally open solenoid valve is set, is connected with PS with threeway between water purifier discharge water mouth and the water tap, with normally open solenoid valve and the PS power series of an end wherein; The other end serial connection 220V power supply; And hummer is set in the middle of normally open solenoid valve and PS, an end of hummer connects normally open solenoid valve and PS, the other end and 220V power series; Between water tap and the threeway reducer union is set, current is reduced to guarantee the pressure of PS through reducer union.

The advantage of the utility model is that PS connection SV is cut off the water supply simultaneously when water purifier leaks, and sends the signal communication buzzer and report to the police, and has avoided the waste of property damage and water resources to greatest extent.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: 1 is that water purifier 2 is water tap for PS 6 for hummer 7 for reducer union 5 for threeway 4 for normally open solenoid valve 3

Fig. 2 is the utility model PS sectional view

8 is that PS loam cake 9 is that retainer spring 12 is that dynamic contactor segment 13 is PS water-in for Static Contact sheet contact 16 receipts pressures promote sealing-ring 17 for PS lower cover 18 for Static Contact sheet 15 for dynamic contactor segment contact 14 for retaining screw 10 for adjustable backstay 11

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

The normally open solenoid valve model of the utility model is: HR1, the hummer model is: BPC30R, PS designs for independent research.

The water purifier of said structure leaks and protects the use of dress to be: the dynamic contactor segment 12 when normally using in the PS is in float state; Fetch boiling water leading 7; Tap water gets into water purifier 1 through normally open solenoid valve 2 and filters; Water after the filtration gets into PS 5 through an end of threeway 3, and the other end flows to water tap 7 through reducer union 4.But when leaking appears in water purifier; Water spills in water purifier 1, and hydraulic pressure are not enough in the PS 5, and dynamically the contactor segment 12 dynamic contactor segment contact 13 that sinks contacts with Static Contact sheet contact 15 on the Static Contact sheet 14; PS 5 is sent signal to hummer 6; Hummer 6 sends chimes of doom, and normally open solenoid valve 2 cuts out simultaneously, cuts off the water supply.

Claims

1. water purifier protector that leaks, it comprises normally open solenoid valve, hummer, PS, threeway and reducer union; It is characterized in that; Between water purifier water-in and tap water water pipe, normally open solenoid valve is set, is connected with PS with threeway between water purifier discharge water mouth and the water tap, with normally open solenoid valve and the PS power series of an end wherein; The other end serial connection 220V power supply; And hummer is set in the middle of normally open solenoid valve and PS, an end of hummer connects normally open solenoid valve and PS, the other end and 220V power series; Between water tap and the threeway reducer union is set, current is reduced to guarantee the pressure of PS through reducer union.
