Abstract
An anti-freezing pressure indicating device mainly comprises a pressure gauge and a gauge valve under the pressure gauge. The anti-freezing pressure indicating device is characterized in that a helix tube is arranged between the gauge valve and a pipe or equipment; a relief valve is arranged on the helix tube near the pipe or the equipment. The pressure gauge and the helix tube of the anti-freezing pressure indicating device are vertically or parallelly arranged on the pipe or the equipement. The anti-freezing pressure indicating device has the advantages that the pressure gauge is connected with the pipe or the equipment through the helix tube, and thus the pressure gauge can be prevented from being frozen in winter; the relief valve is arranged on the helix tube near the pipe or the equipment, the accumulating water in the gauge and the gauge tube is discharged from the relief gauge valve regularly, and the gauge and the helix tube can be simultaneously prevented from being frozen; the safe and normal operation of the pressure gauge in winter can be ensured.
Description
Technical field
The utility model belongs to the pressure indicator, relates to a kind of antifreeze pressure indication mechanism that is installed on pipeline or the equipment, relates to a kind of antifreeze pressure-indication means specifically.
Background technology
In Chemical Manufacture, tensimeter is widely used in various pressure vessels and the pipeline.It reflects current pressure value intuitively, makes producers observe production status smoothly, guarantees safety in production.
Yet in northern China winter open-air device of producing, though the tensimeter of use has certain cold-proof heat insulation measure, some tensimeter parts that still are damaged by frost lose function.As, the table pipe bursting by freezing that has, the table indication is malfunctioning; The valve of the table that has can not normal switch etc., and the safety that has a strong impact on production is sometimes carried out.Because it is automatic continuous production that modern chemical industry is produced majority, it is bigger to stop, open a train loss, will face the operation and the operation of many dangerous operations sometimes.Clean, replace, dismantle, completely cut off, analyze, get angry, install or the like, many danger and loaded down with trivial details work will be done, and take a lot of work, waste and dangerous, and whole device all will move one time.It is the state of " moving and affect whole body "!
Past is in the middle of tensimeter is installed, in order to prevent that tensimeter is subjected to bigger compression shock suddenly, and the table pipe of having taked to connect tensimeter and equipment room is curled into 360 degree circular arc sides, resistance to flow is set impact is slowed down, thereby the restriction fluid impacts the damage that the his-and-hers watches body causes suddenly.
But new problem has occurred again.We know that tensimeter and parts all are vertically mounted on pipeline or the equipment.The shortcoming of 360 degree circular arc table pipes, come out northerly winter.Because media water-bearing part of many productions, being vertically mounted in the degree of 360 on pipeline or the equipment circular arc table pipe just has condensate water to gather, and can't discharge automatically.Water swollen the rising of will freezing when subzero temperature, bursting by freezing table pipe makes the tensimeter indication malfunctioning.If patrol and examine untimelyly or not in place, probably can have an accident.
At present, can see a kind of pressure release table valve on the market, can often discharge ponding tensimeter in by the pressure release of pressure release table valve winter, can prevent that just tensimeter is freezing winter.Yet water row does not go out in the existence table pipe, still can freezing table pipe.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of antifreeze pressure-indication means is provided, and is freezing winter to prevent tensimeter.
Another purpose of the utility model is freezing winter in order to prevent tensimeter and table pipe, and a kind of antifreeze pressure-indication means is provided.
The purpose of this utility model realizes by the following technical solutions:
A kind of antifreeze pressure-indication means, mainly contain tensimeter and under the table valve, it is characterized in that: between described table valve and pipeline or equipment, spiral pipe is installed.
A kind of antifreeze pressure-indication means, mainly contain tensimeter and under the table valve, it is characterized in that: between described table valve and pipeline or equipment, a spiral pipe is installed, near the spiral pipe of pipeline or equipment, a pressure release table valve is installed.
Above-mentioned a kind of antifreeze pressure-indication means, its described tensimeter, spiral pipe is perpendicular or parallel is installed on pipeline or the equipment.
The utility model is compared with prior art compared and is had the following advantages:
The direction that the tensimeter connecting pipe is installed changes, with original vertically arranged connection table pipe, be transformed into the spiral level and install, form is just as a vertical spring of placing, the condensate water that production run is produced flows back in equipment or pipeline or the container endlessly certainly along spiral table pipe.Guarantee that connection table pipe is not damaged by frost, bursting by freezing, tensimeter safety is normally worked accurately.
Be noted that under special circumstances as under the also freezing situation of equipment or trunk line, condensed fluid can't reflux let out clean, also might freezing table pipe and table.The utility model adopts the table valve that has the pressure release function often to get rid of tensimeter and the interior water of spiral pipe, and tensimeter and spiral pipe all are not damaged by frost, and guarantees open-air production safety operation in winter.
Description of drawings
Fig. 1 is the utility model structural representation (tensimeter and spiral pipe are installed in parallel on pipeline or the equipment);
Fig. 2 is the utility model structural representation (tensimeter and spiral pipe are vertically mounted on pipeline or the equipment);
Among the figure,
1-tensimeter 2-table valve 3-spiral pipe 4-blowdown valve 5-pipeline or equipment.
Embodiment
Now, the utility model is further described as follows by the drawings and specific embodiments:
Embodiment
From Fig. 1 and Fig. 2 as seen, a kind of antifreeze pressure-indication means of the utility model, mainly contain tensimeter 1 and under table valve 2, it is characterized in that: between described table valve 2 and pipeline or equipment 5, a spiral pipe 3 is installed.Freezing to prevent the winter tensimeter.
A kind of antifreeze pressure-indication means, mainly contain tensimeter 1 and under table valve 2, it is characterized in that: a spiral pipe 3 is installed between described table valve 2 and pipeline or equipment, near the spiral pipe 3 of pipeline or equipment 5, a pressure release table valve 4 is installed.Can prevent simultaneously that tensimeter and spiral pipe are freezing.
