Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in figure 1, valve gas leak detection device, including supporting construction and detection structure.
Supporting construction includes base 1, and support 2 is provided with base 1, and electric cylinders 3, the end court of electric cylinders 3 are provided with support 2
To the top surface of base 1.
Detection structure includes the lid 6 that can be connected with the open-top screw thread of valve body 4, when lid 6 is screwed in the opening of valve body 4, lid 6
Sealing ring is provided between being open with valve body 4, first through hole, the second through hole, third through-hole and fourth hole are provided with lid 6,
First through hole be with the center of cover plate, first through hole is embedded with matched push rod 7, and scale, push rod are provided with push rod 7
7 top is fixed with the end of electric cylinders 3, and the bottom of push rod 7 is provided with gas cell 9, and fifth hole, the 6th through hole are provided with gas cell 9
With the 7th through hole, the cross section of gas cell 9 after expansion matches with the cross section of the inner chamber of valve body 4, is cylinder after the expansion of gas cell 9
Structure, the second through hole are embedded with air inlet pipe 8, the top connection charger of air inlet pipe 8, and the bottom insertion the 5th of air inlet pipe 8 is led to
Hole, the outer wall of air inlet pipe 8 are fixedly connected with the inwall of fifth hole, and the bottom of air inlet pipe 8 is additionally provided with to be connected with the inner chamber of gas cell 9
Opening, third through-hole is embedded with escape pipe 10, and the top of escape pipe 10 is provided with stop valve 11, the bottom insertion of escape pipe 10
6th through hole, the outer wall of escape pipe 10 are fixedly connected with the inwall of the 6th through hole, and the bottom of escape pipe 10 is additionally provided with and gas cell 9
