Abstract
A siphon pressure gage comprises a copper seat and a bourdon tube connected with the copper seat. A gas chamber is formed in the copper seat, a damping plug is arranged at the gas inlet end of the gas chamber, and a damping hole is obliquely formed in the damping plug. A necking section is arranged at the gas outlet end of the gas chamber, an outlet of the necking section is connected with a capillary tube, and the other end of the capillary tube is connected to the copper seat. According to the technical scheme, the instant pressure impact of a water hammer due to steam cooling can be effectively prevented through the siphon action of the damping hole and the capillary tube at the two ends of the gas chamber. After improvement, the non-return-to-zero defect ratio of pressure is reduced to zero from the original 30%.
Description
Technical field
The present invention relates to a kind of tensimeter, specifically relate to a kind of U trap tensimeter preventing water hammer from occurring.
Background technology
As shown in Figure 1 and Figure 2, the bourdon tube 2 that common tensimeter comprises copper seat 1 and is connected with copper seat 1, arrange air flue 3, and air flue 3 is isometrical in the inside of copper seat 1.
Therefore, when tensimeter uses, due to the impact of site environment, in air flue 3, can water vapour be entered, after too much water vapour cooling, can water hammer be produced.When again leading to steam, the compression shock power meeting surge pressure table that water hammer produces instantaneously, thus bourdon tube is washed out, thus greatly reduce manometric accuracy and serviceable life.
Summary of the invention
The object of this invention is to provide a kind of U trap tensimeter preventing water hammer from occurring.
For achieving the above object, the present invention is by the following technical solutions:
A kind of U trap tensimeter, the bourdon tube that it comprises copper seat and is connected with copper seat, in described copper seat, arrange air chamber, the inlet end of air chamber arranges damping plug, and damping plug surface thereof arranges a damping hole; The outlet side of air chamber arranges necking segment, and the outlet of necking segment connects kapillary, and the other end of kapillary is connected on copper seat.
The diameter of described damping hole is 0.6-1mm, and the diameter of kapillary is 0.2-0.5mm.
The angle of inclination of described damping hole is 100-135 °.
Described necking segment is tapered channel.
Adopt the present invention of technique scheme, by the damping hole at air chamber two ends and the syphonic effect of kapillary, can effectively stop because steam cools the water hammer compression shock instantaneously caused.After improvement, the non return to zero fraction defective of pressure is reduced to zero by original 30%.

Embodiment
As shown in Figure 3, Figure 4, a kind of U trap tensimeter, the bourdon tube 2 that it comprises copper seat 1 and is connected with copper seat 1, in copper seat 1, arrange air chamber 4, the inlet end of air chamber 4 arranges damping plug 5, and damping plug 5 surface thereof arranges a damping hole 6; The outlet side of air chamber 4 arranges necking segment 7, and the outlet of necking segment 7 connects kapillary 8, and the other end of kapillary 8 is connected on copper seat 1.
The diameter of above-mentioned damping hole 6 is 0.6-1mm, can think the arbitrary value in 0.6mm, 0.7mm, 0.8mm, 1mm; The diameter of kapillary 8 is 0.2-0.5mm, can think the arbitrary value in 0.2mm, 0.3mm, 0.4mm, 0.5mm.When the diameter of damping hole 6 is 0.8mm, be preferred forms when the diameter of kapillary 8 is 0.4mm.
The angle of inclination of above-mentioned damping hole 6 is 100-135 °, can think the arbitrary value in 100 °, 110 °, 120 °, 130 ° or 135 °.
Necking segment 7 is tapered channel.
Principle of work of the present invention is: water vapour enters from inlet end, because damping hole 6 is for being obliquely installed, so a small amount of water vapour can not enter in air chamber 4.If there is a large amount of water vapour impact and enter, so water vapour enters after in air chamber 4, because the diameter of air chamber 4 is much larger than the diameter of damping hole, so water vapour can condensation in air chamber 4, can not enter gauge outfit inside.Finally, air chamber 4 connects the less kapillary of a diameter again, thus more effectively ensure that the water hammer that water vapour cooling is formed can not enter gauge outfit inside.Like this, by the damping hole 6 at air chamber 4 two ends and the syphonic effect of kapillary 8, can effectively stop because steam cools the water hammer compression shock instantaneously caused.After improvement, the non return to zero fraction defective of pressure is reduced to zero by original 30%.
