Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
As shown in figure 1, a kind of washing machine sewer pipe air-tightness detection device, including workbench 1, source of the gas 2, first fluid valve
3rd, second fluid valve 4, vacuum generator 5, pressure sensor 6, two-port valve 61, flexible tube base 7, plug seat 8 and indicator lamp 9；
The source of the gas 2 is connected together with three linked piece, forms a two-way source of the gas；The first fluid valve 3 and described
Two fluid valves 4 are two-way valve body；The vacuum generator 5 is three-way device；
The first fluid valve 3 and the second fluid valve 4 are arranged at the both sides of the vacuum generator 5, the vacuum
Generator 5 connects with the first fluid valve 3, the second fluid valve 4 and the pressure sensor 6 respectively；It is described first-class
Body valve 3 and the second fluid valve 4 connect with the source of the gas 2 respectively；The vacuum generator 5 and the pressure sensor 6
Junction is provided with two-port valve 61, and another valve port of the two-port valve 61 connects with the flexible tube base 7；The plug seat 8 and described
Flexible tube base 7 is placed in parallel；
Described in the described 4, vacuum generators 5 of second fluid valve of one 3, one, first fluid valve and one
Pressure sensor 6 forms one group of vacuum group；Be provided with multiple interfaces 71 on the flexible tube base 7, multigroup vacuum group respectively with
The interface 71 connects；Multigroup vacuum group is parallel on the source of the gas 2；Multiple plugs 81 are provided with the plug seat 8,
The plug 81 is corresponding with the interface 71；
The pressure sensor 6 is connected with the indicator lamp 9.
Vacuum generator 5 is vacuumized, passed by pressure in the case where first fluid valve 3 and second fluid valve 4 regulate and control respectively
Sensor 6 is by monitoring the pressure differential in source of the gas 2 and in washing machine sewer pipe, to judge whether the air-tightness of washing machine sewer pipe is complete
It is good.Cracky at the folding of washing machine sewer pipe, causes air-tightness to be deteriorated, and the mode of negative pressure monitors, and washing machine can be arranged
Water pipe has certain protective effect, avoids it from bursting apart.Multi-group vacuum group in parallel can be entered to multiple washing machine sewer pipes simultaneously
Row detection, improve the speed of detection.
Further description, the both sides of the workbench 1 are symmetrically arranged with equally distributed screw, the plug seat 8
It is fixed on by screw on the workbench 1.
For the washing machine sewer pipe of different batches, its length can difference.Plug seat 8 is overall can be in workbench 1
Upper translation, the washing machine sewer pipe for being adapted to different length adjust, and enable devices to test the washing machine of different length
Drainpipe.
Further description, the plug 81 use flexible material, can be rubber, plastics or flexible composite.
The main function of plug 81 is the one end for filling in washing machine sewer pipe, and it is sealed, and washing machine sewer pipe is
Flexible material, plug also use flexible material, and both laminating degrees can be more preferable, sealing effectiveness, and will not be to laundry
Machine drainpipe causes to damage.
Further description, the source of the gas 2, first fluid valve 3, second fluid valve 4, vacuum generator 5 and pressure pass
Connection between sensor 6 uses flexible pipe.
Internal connecting pipe also requires that air-tightness is good, and is easily changed.Because the first fluid valve 3, second of connection
Fluid valve 4 and the quantity of vacuum generator 5 are relatively more, and flexible pipe is more flexible, contribute to the arrangement of pipeline.
Further description, the indicator lamp 9 include red light 91 and green light 92, the switch of the red light 91 and green light 92
By the feedback control of pressure sensor 6.
The lamp of two kinds of colors represents different testing results respectively, and red light represents that air-leakage test is unqualified, and green light represents
Air-leakage test is qualified.Two kinds of lamps can substantially feed back testing result, be easy to pick out the substandard product in washing machine sewer pipe.
Further description, is provided with the truncated cone-shaped of through hole centered on the interface 71, and the interface 71 with it is described soft
The face that base 7 contacts is face larger in two bottom surfaces of round platform.
The design of truncated cone-shaped can make the port of washing machine sewer pipe and interface 71 be brought into close contact, and ensure interface 71 and laundry
The junction air-tightness of machine drainpipe is good, avoids detection error caused by when vacuumizing.
Further description, the plug 81 is truncated cone-shaped, and the plug 81 is with the face that the plug seat 8 contacts
Larger face in two bottom surfaces of round platform.
To ensure that the air-tightness of junction is good when vacuumizing, the design of truncated cone-shaped can make the end of washing machine sewer pipe
Mouth and plug 81 are brought into close contact, and are ensured that the junction air-tightness of plug 81 and washing machine sewer pipe is good, are avoided when vacuumizing
Caused by detection error.
Further description, the washing machine sewer pipe that the washing machine sewer pipe air-tightness detection device one detects simultaneously
Quantity is not more than 10.
The effect that disposably detecting excessive washing machine sewer pipe can cause to vacuumize is deteriorated, and may cause washing machine sewer pipe
Interior too little pressure, it is not easy to detect the pressure change of each washing machine sewer pipe.It can also increase vacuum generator 5 simultaneously
Work load.
Further description, the interface 71 is horizontally disposed, and the plug 81 is vertically arranged.
So setting can allow washing machine sewer pipe to have the bending of an angle, be advantageous to each of washing machine sewer pipe
Extension is opened at folding, makes air-leakage test tighter.
Further description, the material of interface 71 are metal material.
Because it is bigger that pressure is vacuumized at interface 71, more preferable from metal material durability, device is extended
Service life.
Above content is only presently preferred embodiments of the present invention, for one of ordinary skill in the art, according to the present invention's
Thought, there will be changes, this specification content should not be construed as to the present invention in specific embodiments and applications
Limitation.
