Vacuum system, described vacuum system is communicated with described aspirating hole through pipeline, and described pipeline is provided with by-pass valve control and vacuum meter.

As preferably, be provided with the sealing gasket between the shell aperture that is installed in described gland and safety monitoring equipment, to guarantee being tightly connected between gland and the shell aperture.

As preferably, the shape of the shell aperture of described gland and safety monitoring equipment is corresponding, and being more convenient for, both are adjacent to and are tightly connected.The shape here is corresponding to be meant similarly, but the outward flange of gland is bigger than the outward flange of shell aperture, so that compress sealing gasket.

As preferably, between described aspirating hole and described vacuum system, be provided with vacuum buffer tank through pipeline connection, improved the vacuum capability of moment on the one hand, be convenient to stablize vacuum tightness on the other hand.

As preferably, described aspirating hole position has the joint that is used to connect described pipeline, can be connected with pipeline through forms such as screw thread or flanges.

As preferably, be provided with swing arm with power source, this swing arm is hinged on the described gland, can control the gland motion automatically, realizes opening or compressing.Described power source can be motor, cylinder etc. and in addition necessary drive disk assembly, with regard to power source and running part, can adopt prior art.

Described vacuum system can be various types of vacuum pumps or depression generator.

As preferably, be provided with the bearing that is used to place safety monitoring equipment to be detected, the safety monitoring equipment that placement that can be stable is to be detected is avoided rocking.

The bubble-tight device of the utility model fast detecting is tested between the position at gland and test product with sealing gasket; Outwards bleed by the road; Make the inner negative pressure that forms of test product; Whether atmosphere outside pressure can compress gland, has guaranteed the sealing of gland and test product, monitor internal pressure again and change.Realize carrying out the impermeability experiment, product quality is guaranteed by platform.

Description of drawings

Fig. 1 is the bubble-tight apparatus structure synoptic diagram of a kind of fast detecting of the utility model (having comprised safety monitoring equipment to be detected);

Fig. 2 is the structural representation (comprised safety monitoring equipment to be detected and omitted vacuum system and pipeline portions) of the bubble-tight device of fast detecting of the another kind of embodiment of the utility model.

Embodiment

Referring to Fig. 1, the bubble-tight device of a kind of fast detecting of the utility model comprises:

The gland 3 that has aspirating hole, this gland 3 is salable to be connected on the shell aperture of safety monitoring equipment 1, and aspirating hole is communicated with shell aperture; The shell of safety monitoring equipment 1 has two side covers, and one of them is a side cover 2, and another side cover is removed the back and formed shell aperture.

Vacuum system, vacuum system adopt vacuum pump 10 to be communicated with aspirating hole through pipeline, and the aspirating hole position has the joint 5 that is used for connecting line, can be connected with pipeline through thread forms.

Between aspirating hole and vacuum pump 10, be provided with vacuum buffer tank 9 through pipeline connection; Be provided with valve 8 between aspirating hole and the vacuum buffer tank 9; Be provided with valve 11 between vacuum pump 10 and the vacuum buffer tank 9; Be used for the opening and closing of pilot piping, be provided with vacuum meter 6, be provided with vacuum meter 7 near vacuum buffer tank 9 places near the aspirating hole place.
