Abstract
A kind of siphon Pressure gauge, it includes copper seat and the bourdon tube being connected with copper seat, arranges air chamber in described copper seat, and 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 capillary tube, and the other end of capillary tube is connected on copper seat.Adopt the present invention of technique scheme, by the siphonage of the damping hole at air chamber two ends and capillary tube, can effectively stop owing to steam cools down the compression shock of the water hammer moment caused.After improvement, the non return to zero fraction defective of pressure is reduced to zero by original 30%.
Description
Technical field
The present invention relates to a kind of Pressure gauge, concretely relate to a kind of siphon Pressure gauge preventing water hammer from occurring.
Background technology
As shown in Figure 1 and Figure 2, common Pressure gauge includes copper seat 1 and the bourdon tube 2 being connected with copper seat 1, arranges air flue 3 in the inside of copper seat 1, and air flue 3 is isometrical.
Therefore, when Pressure gauge uses, due to the impact of site environment, air flue 3 can enter water vapour, after too much water vapour cooling, water hammer can be produced.When logical steam again, the compression shock power meeting surge table that water hammer moment produces, thus washing out bourdon tube, thus greatly reducing manometric accuracy and service life.
Summary of the invention
It is an object of the invention to provide a kind of siphon Pressure gauge preventing water hammer from occurring.
For achieving the above object, the present invention is by the following technical solutions:
A kind of siphon Pressure gauge, it includes copper seat and the bourdon tube being connected with copper seat, arranges air chamber in described copper seat, and 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 capillary tube, and the other end of capillary tube is connected on copper seat.
The diameter of described damping hole is 0.6 1mm, and the diameter of capillary tube 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 siphonage of the damping hole at air chamber two ends and capillary tube, can effectively stop owing to steam cools down the compression shock of the water hammer moment caused.After improvement, the non return to zero fraction defective of pressure is reduced to zero by original 30%.

Detailed description of the invention
As shown in Figure 3, Figure 4, a kind of siphon Pressure gauge, it includes copper seat 1 and the bourdon tube 2 being connected with copper seat 1, arranges air chamber 4 in copper seat 1, and 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 capillary tube 8, and the other end of capillary tube 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 capillary tube 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, it is preferred forms when the diameter of capillary tube 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.
The operation principle of the present invention is: water vapour enters from inlet end, owing to damping hole 6 is for being obliquely installed, so a small amount of water vapour can not enter in air chamber 4.If there being substantial amounts of water vapour to impact and enter, then water vapour enters after in air chamber 4, owing to the diameter of air chamber 4 is much larger than the diameter of damping hole, so water vapour can condense in air chamber 4, will not enter inside gauge outfit.Finally, air chamber 4 connects a less capillary tube of diameter again, thus more efficiently ensure that the water hammer that water vapour is cooled into will not enter inside gauge outfit.So, by the siphonage of the damping hole 6 at air chamber 4 two ends and capillary tube 8, can effectively stop owing to steam cools down the compression shock of the water hammer moment caused.After improvement, the non return to zero fraction defective of pressure is reduced to zero by original 30%.
