The content of the invention
The purpose of this utility model is to provide a kind of leak tightness test device, to solve what is proposed in above-mentioned background technology Problem.
To achieve the above object, the utility model provides following technical scheme:A kind of leak tightness test device, including examine Groove and pipeline valve, the pipeline valve is positioned at the bottom of the inspection groove, and the inspection groove is built with water, the pipeline valve Below the liquid level of water, the both ends of the pipeline valve are fixedly connected with the first connector and second by adpting flange respectively Connector, first connector are sealed set, and one end of second connector is connected with rubber hose, the inspection groove Side be fixedly installed inflator, be cylindrical cavity, the bottom of the inflator and the rubber inside the inflator Flexible pipe communicates, and the inflator internal-internal is movably set with sealing gasket, and piston rod is fixedly installed at the top of the sealing gasket, The top of the piston rod is located at the outside of inflator, and is fixedly installed pressing plate at the top of the piston rod.
Preferably, the bottom side of the inflator is provided with liquid test agent inlet, the liquid test agent injection Mouth communicates with the inflator.
Preferably, it is installed with stop valve on the liquid test agent inlet.
Preferably, the sealing gasket is connected with the inwall of the inflator using dynamic sealing.
Preferably, the inspection groove is clear glass groove.
Compared with prior art, the beneficial effects of the utility model are:
1st, the both ends of pipeline valve are connected by the utility model with first respectively when carrying out pipeline valve Leakage Test Part and the second connector, pipeline valve can be turned on or off, and be respectively used to examine diverse location, when carrying out air tight test Piston rod is stretched to peak, closes stop valve, presses down on pressing plate, observation examines in groove whether have bubble generation.
2nd, the utility model is when carrying out hydraulic seal inspection, injects colored liquid to inflator, other steps with it is airtight Property examine it is identical, when press pressing plate observation inspection groove in water whether be colored.
