The examination special air gauge of water
This utility model relates to a kind of device for testing mould sealing, particularly relates to a kind of examination vapour pressure table.
Mould after finishing assembly, needs to detect its sealing.Common in the art is to enter with water testing machine
Row detection.This traditional water testing machine detection is once the longest, operation more difficulty, and one group of water route needs complete for 8 minutes,
5 groups of water routes need just can complete for 40 minutes, and work efficiency is more low, and this detection mode effect is limited: mould is slight
The situation water testing machine with infiltration cannot detect.
Utility model content
In order to solve problem above present in background technology, this utility model one examination special air gauge of water, this air pressure
The sealing of mould can be detected by table fast and effectively.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of examination special air gauge of water, including main body tube, it is characterised in that the middle part of described main body tube is provided with air pressure
Table, one end connection of main body tube has pullover, and the other end of main body tube connects air inlet pipe, and the end of air inlet pipe is provided with air pressure
Table air inlet, air gauge air inlet is communicated with main body tube by air inlet pipe, air inlet pipe is provided with for closing air inlet pipe pipeline
Air pressure valve.
Described air inlet pipe is taper.
Described main body tube is flat tube.
Described pullover pullover for outer-hexagonal Stud connection.
The handle of described air pressure valve is arranged on the upper surface of air inlet pipe.
Described main body tube is copper pipe.
Described air gauge is aneroid barometer.
The beneficial effects of the utility model are:
1, Detection results is good, as long as the die waterway through air gauge test ensures that its sealing is up to standard；
2, quickness and high efficiency, average one group of water route has only to 2-3 minute, be tradition water testing machine time-consuming 1/5, and can ensure that examination
Water effect disposably puts in place, reaches the most quick but also practical purpose.
Accompanying drawing explanation
Fig. 1 is the special barometric structural representation of examination water described in the utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of examination special air gauge of water, including main body tube 1, the middle part of main body tube 1 is provided with air gauge 2,
Air gauge 2 is for detecting the air pressure within main body tube 1, and one end of main body tube 1 connects has pullover 3, pullover 3 for connecting mold
Water inlet 4, the most pullover 3 preferably outer-hexagonal Stud connections are pullover, and the other end of main body tube 1 connects taper
Air inlet pipe 6, the end of air inlet pipe 6 is provided with air gauge air inlet 7, and air gauge air inlet 7 is by air inlet pipe 6 and main body tube 1
Communicate, air inlet pipe 6 is provided with the air pressure valve 5 for closing air inlet pipe 6 pipeline.The handle of air pressure valve 5 is arranged on air inlet pipe 6
On upper surface, main body tube 1 and air inlet pipe 3 are all copper pipe, and air gauge 2 is aneroid barometer.
When needs carry out sealing detection to mould, one end of die waterway is accessed air inlet, other end and this examination
The special air gauge of water is connected, and opens air pressure valve 5, when closing gas check valve 5 after gassy in mould.Air gauge 2 is observed after 1-2 minute
Whether pointer situation changes, and represents that mould leaks when air gauge 2 pointer falls after rise, represents when air gauge 2 is slack
Mould is good.
