Wherein, reference title is as follows: 1-outer wall, 2-inwall, 3-sealing gasket, 4-screw hole.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1 and 2, a kind of leakage detector of relief valve, including the female joint being arranged on relief valve, with the detecting system for the leakage of relief valve is detected, described detecting system includes male joint, stop valve, pressure transducer, signal processor and display screen, described male joint is connected with stop valve, and described stop valve is connected with pressure transducer by pipeline, and signal is fed back to display screen by signal processor by described pressure transducer.
Described signal processor includes chip, alarm, electric signal amplifier, analog-to-digital conversion module and level switch module, described chip is connected to pressure transducer, alarm, electric signal amplifier, described electric signal amplifier connects analog-to-digital conversion module, and described analog-to-digital conversion module connects display screen.
Above-mentioned male joint can agree with female joint structure so that male joint and female joint can supporting connect use.
Described female joint includes inwall 2 and outer wall 1, leaves space between the inner and outer wall of described female joint, and the space between described female joint inner and outer wall is annular.Described inwall also includes the sealing gasket 3 that the structure with inner wall outside that inner wall outside is provided with is agreed with；Described outer wall also includes the sealing gasket agreed with inside outer wall structure that inside outer wall is provided with.
Described male joint is that inside is provided with passage column structure, and the cylindrical wall of described male joint may be inserted in the annular space that female joint inner and outer wall is formed, and the structure of size and annular space is agreed with.
Have on the cylindrical wall of described male joint two corresponding can be with screw hole 4, the most all it is provided with two corresponding cylindrical walls with male joint on the inner and outer wall of described female joint to tighten up a screw the identical screw hole of hole dimension, after making male joint can be inserted into annular space, by passing screw rod in male joint and female joint, fix with nut again, so that male joint and the fixing connection of female joint.
