Description
Technical field
This utility model relates to the inorganic core Pressure gauge of a kind of damp type.
Background technology
Pressure gauge refers to flexible member as sensing element, measures and indicates the instrument higher than ambient pressure, applying extremely widespread, and it is almost throughout all of industrial flow and scientific research field.It is seen everywhere in fields such as heat distribution pipe network, oil gas transmission, water and air supply system, vehicle maintenance maintenance factory shops.Especially during industrial stokehold and commercial measurement, owing to the elastic sensing element of mechanical compression table has the highest mechanical strength and the characteristic such as convenient for production so that mechanical compression table is increasingly widely applied.
Existing Pressure gauge is typically with movement, the assembly of movement is more, and structure is complicated, and manometric working environment is the most severe, the manometric original paper of conventional belt movement is easily subject to damage or deformation, thus stability declines, and affects measurement effect, and conventional pressure table assembles trouble, with high costs.
Summary of the invention
In order to overcome existing manometric above-mentioned deficiency, this utility model provides the inorganic core Pressure gauge of the damp type of a kind of good stability.
The technical scheme in the invention for solving the technical problem is: the inorganic core Pressure gauge of a kind of damp type, including joint, it is provided with gas channel in described joint, the side of described joint is provided with a c-type bourdon tube, the front end of described c-type bourdon tube is provided with one silently, the upper surface of described joint offers groove, the first through hole is offered in described groove, it is equipped with central shaft in the first described through hole, U-shaped crank also it is arranged with on described central shaft, described silently and between described U-shaped crank, be provided with a drive link, the front-end and back-end of described drive link are equipped with crotch, described is silently equipped with connecting hole with U-shaped crank, described crotch hooks into described connecting hole, the bottom of described gas channel is additionally provided with a damp screw.
Further, also including that gag lever post, described gag lever post are provided with the second through hole, described the second through hole described in central shaft insertion, the front end of described gag lever post is provided with boss, and the diameter of described boss is more than the diameter of described first through hole.
Further, described U-shaped crank is welded as a whole with described gag lever post, and described central shaft is welded as a whole with described U-shaped crank.
Further, one end of described c-type bourdon tube is integrated with described weld, and the other end of described c-type bourdon tube is silently welded as a whole with described.
The beneficial effects of the utility model are: 1. this utility model uses between inorganic core structure, and crotch design and each assembly on drive link by being welded and fixed so that overall structure is simple, and stability is greatly improved；2., by being arranged on the damp screw bottom gas channel, reduce impulsive force during air-flow entrance passage, thus preferably protect pressure gauge component, increase the service life.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial sectional view of the present utility model.
Fig. 3 is the structural representation of drive link.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
With reference to Fig. 1, a kind of inorganic core Pressure gauge of damp type, including joint 1, it is provided with gas channel 2 in described joint 1, the side of described joint 1 is provided with a c-type bourdon tube 3, the front end of described c-type bourdon tube 3 is provided with one silently 4, the upper surface of described joint 1 offers groove 5, the first through hole is offered in described groove 5, it is equipped with central shaft 6 in the first described through hole, U-shaped crank 7 also it is arranged with on described central shaft 6, described is silently provided with a drive link 8 between 4 and described U-shaped crank 7, the front-end and back-end of described drive link 8 are equipped with crotch 9, described silently 4 and U-shaped crank 7 be equipped with connecting hole 10, described crotch 9 hooks into described connecting hole 10.The bottom of described gas channel 2 is additionally provided with a damp screw 11, can reduce impulsive force during air-flow entrance passage, thus preferably protect pressure gauge component, increase the service life.
This utility model is owing to using inorganic core structure, and by being welded and fixed between crotch design and each assembly on drive link, so that overall structure is simple, under rugged environment, shock resistance is strong, and stability is also greatly improved.
In the present embodiment, also including that gag lever post 12, described gag lever post 12 are provided with the second through hole, described central shaft 6 inserts the second described through hole, and the front end of described gag lever post 12 is provided with boss 13, and the diameter of described boss 13 is more than the diameter of described first through hole.Described U-shaped crank 7 is welded as a whole with described gag lever post 12, and described central shaft 6 is welded as a whole with described U-shaped crank 7.By boss 13, central shaft 6 is carried out the most spacing, more spacing to central shaft 6 by welding so that relative displacement will not occur, so that the data measuring gained are more accurate between central shaft 6 and U-shaped crank.
In this utility model, one end of described c-type bourdon tube 3 is welded as a whole with described joint 1, and the other end of described c-type bourdon tube 3 silently 4 is welded as a whole with described.Air-flow will not be leaked outside, it is ensured that the accuracy of the data that Pressure gauge is measured.
