Sealing sealing.
The compress cell is gas booster pump, and the outlet of the gas booster pump connects pressurizing duct, and the pressurization is led
A through-hole of the pipe across the pot cover upper surface of pressure cooker to be measured is connected to inside pressure cooker to be measured.Compress cell is set, it can be with mould
Intending pressure cooker to be measured, there is a situation where pressure anomalies due to outlet hole plug.
The gas booster pump is connect with data processing unit.By the output pressure and the air pressure that compare gas booster pump
Air pressure in the pot that sensor measures, it can be deduced that pressure cooker sealing performance to be measured.
The heating unit is gas furnace, and when test, water is filled in the pressure cooker to be measured, gas furnace is arranged, can be with
Simulate the case where pressure cooker to be measured is in normal use.
The data processing unit is computer.The data from baroceptor that computer will receive, with it
For ordinate, the time is abscissa, air pressure change situation in real time monitoring band side pressure cooker.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) by the device, normal holding internal pressure, vent pressure and the sealing performance of pressure cooker, structure letter can be examined
It is single；
(2) air pressure change situation in real time monitoring band side pressure cooker, monitoring data accuracy are good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the testing result figure that computer obtains in embodiment 1.
Wherein, 1 is pressure cooker to be measured, and 2 be gas furnace, and 3 be baroceptor, and 4 be computer, and 5 be gas booster pump, 6
It is water for sealant, 7,8 be relief valve, and 9 be explosion-proof valve, and 10 be pressurizing duct, and 11 be check valve.
Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is unlimited
In following embodiments.
Embodiment 1
A kind of device for pressure cooker performance test, structure is as shown in Figure 1, include for adding to pressure cooker 1 to be measured
Heat gas furnace 2, with inside pressure cooker 1 to be measured by pressurizing duct 10 be connected to for pressurize gas booster pump 5, be arranged to
It surveys inside pressure cooker 1 based on detecting in pressure cooker 1 to be measured the baroceptor 3 of air pressure and being connect with baroceptor 3
Check valve 11 is arranged in calculation machine 4 on pressurizing duct 10.
The pot cover upper surface of pressure cooker 1 to be measured is set there are two through-hole, connects baroceptor 3 and the conducting wire of computer 4 is worn
A through-hole is crossed, pressurizing duct 10 passes through another through-hole and is connected to inside pressure cooker 1 to be measured, and through hole is close by sealant 6
Envelope.
Gas booster pump 5 is connect with computer 4.By the output pressure and baroceptor 3 that compare gas booster pump 5
Air pressure in the pot measured, it can be deduced that 1 sealing performance of pressure cooker to be measured.
Above-mentioned apparatus is used to detect certain brand pressure cooker, steps are as follows:
(1) each component is connected by Fig. 1；
(2) gas furnace 2 is opened, the water 7 in pressure cooker 1 to be measured is heated, makes water heating evaporation, 1 air pressure in pressure cooker to be measured
It gradually rises；5 air pressure change of gas booster pump is checked by computer 4, when vapor is sprayed from relief valve 8, height to be measured
After air pressure tends towards stability in pressure pot 1, stationary value is read, is compared with the operating pressure of pressure cooker 1 to be measured, judges whether it closes
Lattice；
(3) relief valve 8 is blocked, check valve 11 is opened, is pressurized using gas booster pump 5 into pressure cooker 1 to be measured, reaches peace
A certain atmospheric pressure value under total pressure closes check valve 11, at this point, gas booster pump 5 does not continue to be pressurized, observes gas booster pump
Stable gas pressure situation in 5；
(4) check valve 11 is opened, continues to be pressurized into pressure cooker 1 to be measured, until explosion-proof valve 9 ruptures, pressure cooker 1 to be measured is anxious
Acute pressure release observes 1 highest of pressure cooker to be measured and bears pressure.
The barometric information that computer obtains is as shown in Fig. 2, therefrom it will be seen that the operating pressure of the pressure cooker to be measured
In 161KPa or so, leakproofness declines not seriously in 30min, i.e., leakproofness is good, and the safe pressure of the pressure cooker to be measured is
189KPa checks the pot body and lid of the pressure cooker to be measured, does not find obvious cracks after terminating test.
Compared with the factory specification of the pressure cooker to be measured, operating pressure 160KPa, safe pressure 190KPa, card
Bright, the pressure cooker performance to be measured is qualified.
