Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1 to Fig. 5, a kind of embodiment provided by the utility model：A kind of Leakproof safety manometer, including
Watchcase 1, pressure valve main body 5, anti-leak frame body 14 and flexible member 18,1 inside front of watchcase are provided with dial plate 2, dial plate
Show pressure scale on 2, the installation of the 1 inside back side of watchcase has elastic component 18, and indicator 9, indicator 9 are provided with flexible member 18
On dial plate 2, flexible member 18 connects connecting rod 20, is provided with Bourdon tube 21 on connecting rod 20, when fluid flows through Bourdon tube 21,
Bourdon tube 21 can produce corresponding deformation, it is driven connecting rod 20, so as to drive flexible member 18 to rotate, finally so that indicator 9
Corresponding scale is turned to, 1 external upper face of watchcase is provided with implementation of port 10, and implementation of port 10 is supporting to be provided with sealing cover, filling
It may be such that the effective antidetonation of pressure gauge after liquid, watchcase 1 is provided with meter connector 19 immediately below outside, and 1 back side of watchcase is provided with table
