Description
Technical field
The present invention relates to heating and ventilating equipment detection fields, more particularly, to a kind of temperature sensitization apparatus performance test machine.
Background technique
HVAC is a component part of building.Full name in discipline classification is heat supply for combustion gas ventilation and air-conditioning man
Journey, comprising: these three aspects of heating, ventilation and air conditioning, functionally and the indispensable a part of future home.
Heating (Heating) --- it also known as heats, supplies load to building as needed, guarantee that room temperature is wanted by people
It asks and is persistently higher than external environment.It is usually combined with components such as caliduct, radiators and achievees the purpose that heating.
The caliduct in winter, nobody, when not needing radiator, can not shut completely indoors, be easy because it is cold
Caliduct is freezing, so having a minimum heating flow automatic by caliduct is right.In order to reach this purpose, simultaneously
A large amount of heating is avoided to waste, it will usually install TRV thermostat valve additional on caliduct, the quality of TRV thermostat valve affects entirely
The service life of HVAC system.It before TRV thermostat valve is typically mounted at radiator, is usually made of temperature-sensitive part and valve body, core
Center portion part is the temperature sensor unit of temperature-sensitive part --- temperature sensitization apparatus, and temperature sensitization apparatus can incude the change of ambient temperature
Change and generate volume change, regulation valve core is driven to generate displacement, and then flow automatic regulation, realizes the room temperature that resident needs.
Currently, generally TRV thermostat valve the whole series are tested in HVAC industry, it, often can only be to TRV when testing out abnormal
Thermostat valve product carries out whole preliminary judgement, and can not accurately understand the core component of this product --- temperature sensitization apparatus whether work
Make that performance is normal, since the performance of temperature sensitization apparatus directly affects and decide the quality of TRV thermostat valve, if it is possible to specifically for
Temperature sensitization apparatus is tested, and the qualification rate of TRV thermostat valve product can be greatly improved, and the matter of TRV thermostat valve is judged for user
Amount quality and maintenance orientation problem provide reliable guidance.
Summary of the invention
The present invention is to overcome above situation insufficient, it is desirable to provide one kind can be specifically for the temperature sensitization apparatus of TRV thermostat valve
The test machine tested.
A kind of temperature sensitization apparatus performance test machine, for detecting the performance of the temperature sensitization apparatus in thermostat valve, including
Test machine main body, thermostatic water bath, testing jig, feeler lever, size sensor, counterweight, display screen and operation button.
The temperature sensitization apparatus include temperature sensitization apparatus shell, bellows, adjustment pressing tongs, seal steel ball, lead warm medium, bottom cover and
Inner hole；The temperature sensitization apparatus shell is in the convex of bottom end opening, inside bellows is installed, and in temperature sensitization apparatus shell
Opening is welded with bottom cover by scolding tin, and the inner hole of face and diaphragm for passageway is offered on the bottom cover, leads warm media filler
Between the temperature sensitization apparatus shell and the bellows, the temperature sensitization apparatus carries out adjustment by adjustment pressing tongs；
The test machine main body is equipped with the thermostatic water bath, is fixedly installed with the test above the thermostatic water bath
The temperature sensitization apparatus to be tested is placed in frame, the lower section of the testing jig, described in the water level in the thermostatic water bath at least covers
The half height of temperature sensitization apparatus, the inner hole that one end of the feeler lever passes through the temperature sensitization apparatus extend to bellows interior, so that
The end of feeler lever is at least contacted with a part of bellows, after the other end of feeler lever passes vertically through testing jig, in being somebody's turn to do for feeler lever
The other end places the counterweight, and feeler lever is located at the part at counterweight and binds with the size sensor, the size sensor and
The host computer for serving as control device is connected and is communicated；The temperature change and Yin Re of program record thermostatic water bath in host computer
The stroke of feeler lever caused by the height change of bellows in sensor changes, and according to formula, i.e., every degree lift=total kilometres become
Every degree lift of the temperature sensitization apparatus is calculated in change/temperature difference, draws every degree lifting curve figure automatically and by the display
It is compared display with every degree lift theory curve by screen, and the feeler lever recorded according to program water temperature in thermostatic water bath
The difference for rising 20 DEG C of stroke and the stroke of 20 DEG C of decline, is calculated the lagged value of the temperature sensitization apparatus.
During testing temperature sensitization apparatus performance, external power supply is supplied to host computer and thermostatted water by test machine main body
Slot, then out of, size sensor provides a signal to host computer program, computer program record thermostatic water bath temperature change and
Feeler lever height change caused by bellows height change inside temperature sensitization apparatus, wherein 5-30 DEG C of thermostatic water bath persistently overheating or
Cool down 30-5 DEG C, change of the size sensor in 0.2 DEG C every liter of thermostatic water bath or drop feeler lever of 0.2 DEG C of record during alternating temperature
Change, can obtain every degree lift, i.e., every degree lift=total kilometres variation/temperature difference (such as 25 DEG C), total kilometres variation in the process
Height change as between feeler lever original state and terminal state；The stagnant of temperature sensitization apparatus during alternating temperature twice is then calculated again
After be worth, i.e., record feeler lever rises 20 DEG C to 20 DEG C of strokes of decline in thermostatic water bath, and it is lagged value, heat that the two, which subtracts each other the difference obtained,
The lagged value of sensor is qualification no more than 0.25mm.
As a further solution of the present invention: there are three the adjustment pressing tongs is total, in adjustment pressing tongs adjustment temperature sensitization apparatus,
Adjustment pressing tongs must not orientation where face sealing steel ball.
As a further solution of the present invention: the diameter of the sealing steel ball is 2mm.
As a further solution of the present invention: the diameter of the inner hole is 9.3mm.
As a further solution of the present invention: the reaction speed of the temperature sensitization apparatus, that is, every degree lift meets 0.22 ±
When 0.01mm (EN215 standard), temperature sensitization apparatus is qualified products.
As a further solution of the present invention: opened on the testing jig there are two aperture, aperture and feeler lever clearance fit, led to
The limit for crossing two apertures makes feeler lever displacement.
As a further solution of the present invention: the quality of the counterweight is 5kg.
Compared with prior art, the beneficial effects of the present invention are:
The present invention is solved to be formerly only available and be tested TRV thermostat valve the whole series, cannot get information about temperature sensitization apparatus spy
Property deficiency can be apparent from the correlation properties of temperature sensitization apparatus, and present invention behaviour by detecting every degree lift and lagged value
Make simple, automatic test and record and can obtain a result.
