Fig. 2 is the rack and its relevant portion structural schematic diagram of instantaneous water heater's security appliance test device.
Specific embodiment
A kind of instantaneous water heater's security appliance test device, such as Fig. 1, including for the confession to water supply of water heater and draining
Water system provides the power supply system of power supply to water heater, and the monitoring system and controller for monitoring water heater operating status supply water
System and the controller 1 of power supply system work.
The water system, water inlet pipe 11 and outlet pipe 12 including being separately connected the inlet and outlet of water heater,
The solenoid valve that solenoid valve 14 controls the on-off of water flow is respectively provided on water inlet pipe and outlet pipe.
The power supply system, including power supply, transformer 21 and the relay 22 for controlling its on-off of power supply.
The monitoring system, such as Fig. 1, including, for measuring the temperature sensor 31 of water heater temperature, for measuring hot water
The pressure sensor 32 of device inside water pressure.
Temperature sensor 31 and pressure sensor 32 can be installed only on the water inlet pipe or outlet pipe of water heater, can also be with
Inlet tube and outlet tube is all installed simultaneously.
The temperature sensor, pressure sensor pass through analog-digital commutator and are connected to control device, by monitoring signals
Input to controller, monitoring signals by pre-set programs issue control instruction to controller based on the received, control power supply system after
The on-off of two solenoid valves of on-off and water system of electric appliance, to control power supply system and water system work.
The test device controls the open and close control water system of the solenoid valve on inlet pipeline by controller, realizes
Control to water heater water supply and draining；By controller control power supply system transformer and relay work, it can be achieved that
Control to supply voltage size and on-off；The parameters control that controller is fed back by preset test procedure and monitoring system
The work of water system, power supply system processed, and the parameters of record monitoring system feedback, can automatically control every security appliance
The progress of performance test, and whole data are recorded in real time.It realizes entire instantaneous water heater's security appliance test device
Automatic to carry out, test process does not depend on artificial on duty, and test operation is simple and convenient, is significantly reducing artificial workload, is mentioning
The high safety and accuracy of test.
In the safety feature test of instantaneous water heater, airtightness is an important index, at present water heater airtightness
Test, mainly by hydraulic pressure certain in keeping water-heater water tank in the case where, observe by the naked eye with the presence or absence of leakage
The phenomenon that judge.It is inconvenient that it is observed, and when leaking smaller, there is the case where not observing, there are errors for measurement.
In order to improve the accuracy of measurement, the also settable water inlet pipe and outlet pipe for being mounted on water heater of the monitoring system
Flow measurement device 33, the flow measurement device measures the flow of water inlet pipe and outlet pipe respectively, and passes through analog-to-digital conversion
Device is connected to controller, and monitoring signals are transferred to controller.The difference in flow that controller passes through comparison outlet pipe and water inlet pipe
It is different, therefore, it is determined that the airtightness of cabinet.It is convenient that it is not only measured, and can accurately still monitor when leaking minimum, and can give
Numerical evaluation out, monitoring is intuitive, accuracy is high.
Its power of instantaneous water heater is very high, usually 5kW or more, is very easy to occur in water flow test on fire existing
As.Test device of the invention supplies water, for electrically separated, is individually carried out by power supply system and water system respectively；Respectively by not
With solenoid valve and relay controlled by controller, when judge that sample is unqualified, such as leak, control power supply system with
The controller of water system work, can control power supply system and is powered off, and stop sample power supply；And control water system continuation
Work is supplied water without stopping, and normal-temperature water is made still normally to flow through sample pipeline after water heater stops powered operation, to rise
To cooling effect, sample is avoided to smolder because on fire after test failure, jeopardizes testing staff or damage experimental facilities facility,
It ensure that the safety of test device well.
Instantaneous water heater needs to carry out the water pressure test, and the water pressure test needs the specified hydraulic pressure for making water heater at 1.5 to 2 times
It works under state and water-tight and generation is permanently deformed.Instantaneous water heater's security appliance test device of the present invention,
Pressure sensor can easily monitor the hydraulic pressure inside water heater, and the flow measurement device of water inlet pipe and outlet pipe can be examined
Survey the flow of water inlet pipe and outlet pipe；It is boosted by Control experiment hydraulic pressure, reaches water heater pressure by pressure sensor monitoring
To test demand, then by the flow of monitoring Inlet and outlet water water pipe, the size and variation of observed volume can be quick and precisely convenient
Identify measured sample whether leak.To judge whether to meet standard requirements.The test device, can be very easily real
The existing water pressure test.
In addition, water heater also needs to carry out water flow test, need water heater that can establish stable work under low discharge
Make state.During the test, the temperature controller of water heater requires to disconnect at 98 degrees Celsius, realizes protection.This experiment, due to
The high-power reason of fast water heater, there are biggish difficulty and risk.Firstly, its flow is difficult to control；Once secondly, temperature
Be failure to actuate when device high temperature, occur it is unqualified, continue power supply tested in be just easy to it is on fire, to jeopardize testing staff or damage
Bad experimental facilities, in some instances it may even be possible to develop as fire.
In order to overcome the problems referred above, instantaneous water heater's security appliance test device of the present invention, inlet pipeline are set
The adjustable battery valve of aperture can be used in the solenoid valve set, and controls its aperture by controller, can easily control water heater
Water flow.Meanwhile test device of the invention, controller can when sample water flow test is unqualified, control water system into
The solenoid valve of outlet pipe still stays open, and still supplies water to water heater；And the relay of control of power supply system on/off is then
It disconnects, does not power to water heater, avoid further heating.It can be realized when protection act does not occur for temperature controller at high temperature
To the water supply of water heater without powering, so as to cool down to water heater, avoid because on fire caused by after failed sample
Phenomenon further improves safety.
