Abstract
The utility model provides a multichannel vacuum is revealed test and is used water level case belongs to airtight test technical field, including box, a plurality of indicator tube and trachea, its characterized in that, a plurality of the indicator tube is installed inside the box, trachea one end with the indicator tube is connected, and a plurality of is connected with external test mechanism to the other end the indicator tube is equipped with two rows, two rows be fixed with board in a poor light between the indicator tube, observation part has been seted up to the box lateral wall, observation part with the indicator tube corresponds. The utility model provides a multichannel vacuum is revealed test and is used water level case, through the change of water level in the observation part observation indicator tube, the water level surpasses indicating line, judges then that there is the vacuum in the workpiece for measurement and leaks. The advantage that possesses simple structure, reasonable in design, stable performance, long service life.
Description
Technical field
The utility model belongs to airtight technical field of measurement and test, and water level case is used in a kind of especially multichannel vacuum leak test.
Background technology
At present, test for the vacuum-tightness of water heating bathroom workpiece, mainly tested using pressure sensor, but
In test process, often there is sensor and outranges to use in Jing, if being applied above the pressure of rated insulation voltage power again, easily causes pressure
The breakage of force snesor.
Utility model content
The utility model provides a kind of multichannel vacuum leak test and uses water level case, and simple structure, reasonable in design, performance are steady
Fixed, long service life.
The utility model specifically adopts the following technical scheme that realization：
A kind of multichannel vacuum leak test water level case, including casing, several indicate to manage and tracheae, described in several
Indicate that pipe is arranged on the box house, described tracheae one end is connected with the instruction pipe, and the other end connects with external testing mechanism
Connect, several described instruction pipes are provided with two rows, and backlight is fixed between instruction pipe described in two rows, and the wall box is offered
Observation portion, the observation portion is corresponding with the instruction pipe.
Preferably, indicating to connect by current limiting tube between pipe described in two rows.
Preferably, the observation portion side of the wall box is also etched with water level instruction line.
Preferably, the backlight is LED/light source, it is fixed on background board.
The multichannel vacuum leak test that the utility model is provided uses the water level case, its advantage to be：By observation portion
Observation indicates the change of water level in pipe, and water level exceedes instruction line, then judge that workpiece for measurement has vacuum leak.Possesses structure letter
Single, reasonable in design, stable performance, the advantage of long service life.

Specific embodiment
To further illustrate each embodiment, the utility model is provided with accompanying drawing.These accompanying drawings are in the utility model is disclosed
A part for appearance, it is mainly to illustrate embodiment, and the running that the associated description of specification can be coordinated to explain embodiment is former
Reason.Coordinate and refer to these contents, those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantage of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As Figure 1-3, the present embodiment proposes that water level case, including casing 1, water tank are used in a kind of multichannel vacuum leak test
Inside fix several and indicate pipe 2, totally two ten four instruction pipes 2,24 indicate that pipes 2 are divided into two rows in the present embodiment, often arrange
12, two rows indicate to connect by current limiting tube 3 between pipe 2, and two rows indicate to be fixed with backlight 4 between pipe 2, and backlight 4 is pacified
It is mounted on background board 5.Observation portion 6 is offered in one of side wall of casing 1, observation portion 6 offers 12 in the present embodiment
It is individual, indicate that pipe 2 is corresponded with a wherein row, also it is etched with water level instruction line 7 in observation portion side.Near the side of observation portion 6
12 instruction pipes 2, be respectively connected with tracheae 8, the other end of tracheae 8 is connected with outside mechanism for testing.
Water level case is used in the multichannel vacuum leak test that the utility model is provided, when the workpiece for measurement on mechanism for testing is not deposited
In vacuum leak, indicate that the water level in pipe 2 is less than water level instruction line 7, let out when the workpiece for measurement on mechanism for testing has vacuum
During leakage, indicate that the water level in pipe 2 rises, higher than water level instruction line 7.The change of water level in pipe 2 is indicated by observation, you can judge
Workpiece for measurement whether there is vacuum leak, and be installed behind the backlight 4 of LED/light source in instruction pipe 2, more using observation
Water level.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, in the spirit and scope of the present utility model limited without departing from appended claims, in form and details
On the utility model can be made a variety of changes, be protection domain of the present utility model.
