Abstract
The utility model relates to a bellows type pressure gauge comprising a gauge outfit and a gauge joint arranged at the lower end of the gauge outfit, wherein a connecting flange is arranged on the gauge joint, a silica-gel corrugated liquid storage tube is arranged below the connecting flange, and a protective tube with a lower opening is sleeved outside the silica-gel corrugated liquid storage tube. Because the protective tube with the lower opening is sleeved outside the silica-gel corrugated liquid storage tube, the protective tube can reduce the impact force of pressure fluid, thereby acting as a protective action to the silica-gel corrugated liquid storage tube. A bellows can extend into a pressure pipeline, which is not easy to damage and prolongs the service life.
Description
(1) technical field
The utility model relates to a kind of bellows manometer.
(2) background technology
Existing bellows manometer, the meter connector that comprises gauge outfit and be located at this gauge outfit lower end, this meter connector is provided with joint flange, the below of this joint flange is provided with silica gel corrugated liquid storage pipe, be provided with pressure conduction filling liquid in this silica gel corrugated liquid storage pipe, by the pressure of silica gel corrugated liquid storage pipe induction fluid.But existing this bellows manometer is difficult to accomplish corrugated tube is stretched in the pressure pipeline, because pressure fluid directly contacts with silica gel corrugated liquid storage pipe, if the pressure of pressure fluid is too big, can directly collide silica gel corrugated liquid storage pipe, thereby damage silica gel corrugated liquid storage pipe easily.Will not exert an influence to measuring accuracy but corrugated tube is not extend in the pressure pipeline.
(3) summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides a kind of bellows manometer that corrugated tube can be extend in the pressure pipeline.
The technical scheme in the invention for solving the technical problem is: a kind of bellows manometer; the meter connector that comprises gauge outfit and be located at this gauge outfit lower end; this meter connector is provided with joint flange; the below of this joint flange is provided with silica gel corrugated liquid storage pipe, and described silica gel corrugated liquid storage pipe is arranged with the protection tube with under shed outward.
Be filled with pressure conduction filling liquid in the silica gel corrugated liquid storage pipe; in use; silica gel corrugated liquid storage pipe is stretched in the pressure pipeline; joint flange and pressure pipeline fix; pressure fluid contacts with the outer wall of protection tube earlier in flow process; walking around protection tube then enters in the protection tube from the lower opening of protection tube and contacts with the outer wall of silica gel corrugated liquid storage pipe; by the pressure of silica gel corrugated liquid storage pipe induction fluid, enter the indirect measurement that realizes pressure in the gauge outfit then thereby make the interior pressure of silica gel corrugated liquid storage pipe conduct filling liquid.
The beneficial effects of the utility model are: because silica gel corrugated liquid storage pipe is arranged with the protection tube with under shed outward; protection tube can reduce the impulsive contact force of pressure fluid; thereby silica gel corrugated liquid storage pipe is shielded; corrugated tube can be extend in the pressure pipeline; not fragile, prolonged serviceable life.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
A kind of bellows manometer; the meter connector that comprises gauge outfit 1 and be located at this gauge outfit 1 lower end; this meter connector is provided with joint flange 2, and the below of this joint flange 2 is provided with silica gel corrugated liquid storage pipe 3, these silica gel corrugated liquid storage pipe 3 outer protection tubes 4 with under shed that are arranged with.
Be filled with pressure conduction filling liquid 5 in the silica gel corrugated liquid storage pipe 3; in use; silica gel corrugated liquid storage pipe 3 is stretched in the pressure pipeline 6; joint flange 2 fixes with pressure pipeline 6; pressure fluid 7 contacts with the outer wall of protection tube 4 earlier in flow process; walking around protection tube 4 then enters in the protection tube 4 from the lower opening of protection tube 4 and contacts with the outer wall of silica gel corrugated liquid storage pipe 3; protection tube 4 can reduce the impulsive contact force of pressure fluid 7; thereby silica gel corrugated liquid storage pipe 3 is shielded; by the pressure of silica gel corrugated liquid storage pipe 3 induction fluids, enter the indirect measurement that realizes pressure in the gauge outfit 1 then thereby make silica gel corrugated liquid storage pipe 3 interior pressure conduct filling liquid 5.
Claims (1)
1. bellows manometer; the meter connector that comprises gauge outfit and be located at this gauge outfit lower end; this meter connector is provided with joint flange, and the below of this joint flange is provided with silica gel corrugated liquid storage pipe, it is characterized in that: described silica gel corrugated liquid storage pipe is arranged with the protection tube with under shed outward.
