Abstract
The utility model discloses a pressure measuring device for a high-temperature pressure vessel. The pressure measuring device comprises a strain box (1), a metal tube (2) and a pressure measuring instrument (3), wherein the interior of the strain box (1) is provided with an empty cavity, one end of the metal tube (2) is communicated with the empty cavity inside the strain box (1), the other end of the metal tube (2) is connected with the pressure measuring instrument (3), and the strain box (1) and the metal tube (2) are provided with heat conducting oil in the interior respectively. Compared with the traditional technology, the pressure measuring device can drive the heat conducting oil to generate a certain pressure through the elastic deformation of the strain box, thus a pressure in the high-temperature pressure vessel is indirectly measured through measuring the pressure by using the pressure measuring instrument, and the metal tube can dissipate the heat transferred to the heat conducting oil from the high-temperature pressure vessel, so that the temperature of the metal tube and the heat conducting oil which are in contact with the pressure measuring instrument is within a bearable temperature range of the pressure measuring instrument, thereby avoiding the problem of inaccurate pressure measurement due to damages to the pressure measuring instrument by high temperature.

Background technology
High temperature pressure vessel is widely used in work, agricultural production.In actual production, in order to make the internal pressure of pressure vessel well be monitored or pressure vessel is used within the scope of pressure-bearing, must monitor the pressure of its internal tank, to reach predetermined production effect or to avoid the generation of security incident.Because the carrying temperature of pressure instrumentation is mostly below 100 ℃, if when pressure instrumentation directly detects the pressure in high temperature pressure vessel, be subject to the meeting build-up of pressure that affects of temperature to measure inaccurate problem, also do not have good method to solve the pressure measurement problem of high temperature pressure vessel at present.
Utility model content
The purpose of this utility model is to provide a kind of high temperature pressure vessel pressure tester, this device can be measured the force value of high temperature pressure vessel inside accurately, makes the pressure of high temperature pressure vessel inside obtain accurate detecting/monitoring and avoid the safety problem of bringing because pressure is excessive.
The technical solution of the utility model: a kind of high temperature pressure vessel pressure tester, comprise strain box, metal tube and pressure instrumentation, strain box inside is provided with cavity, metal tube one end is connected with the cavity of strain box inside, the other end of metal tube is connected with pressure instrumentation, in strain box and metal tube, be equipped with conduction oil, strain box adopts high temperature resistant resilient material to make, under the effect of high temperature pressure vessel, can make strain box that certain elastic deformation occurs and make the certain pressure of the inner generation of conduction oil, pressure instrumentation can be determined the pressure in high temperature pressure vessel by measuring this force value.
Aforesaid this high temperature pressure vessel pressure tester, metal tube middle part is helicoidal structure, can increasing heat radiation area by helicoidal structure is set, the heat that makes high temperature pressure vessel pass to conduction oil and metal tube leaves fast, avoids the impact of heat on pressure instrumentation.
Aforesaid this high temperature pressure vessel pressure tester, the helicoidal structure outside at metal tube middle part is provided with cooling device, increases cooling device and also can improve radiating efficiency, and the pressure that pressure instrumentation is measured is more accurate.
Aforesaid this high temperature pressure vessel pressure tester, cooling device is provided with heat eliminating medium entrance and heat eliminating medium outlet, heat eliminating medium can enter cooling device from heat eliminating medium entrance, and the heat eliminating medium in cooling device is discharged from heat eliminating medium outlet after absorbing heat.Described heat eliminating medium is water or cold oil.
Aforesaid this high temperature pressure vessel pressure tester, the material of metal tube is copper or aluminium alloy, copper and aluminium alloy have good thermal conductivity, and the heat in conduction oil is shed fast, have avoided making it measure inaccurate problem because of conduction oil to the damage of pressure instrumentation.
Aforesaid this high temperature pressure vessel pressure tester, pressure instrumentation is condenser type manograph or strain-type manograph.
Compared with conventional art, the utility model can make conduction oil produce certain pressure by the elastic deformation of strain box, measure this pressure by pressure instrumentation and indirectly measure the pressure in high temperature pressure vessel, wherein metal tube can dissipate high temperature pressure vessel and be delivered to the temperature of conduction oil, in carried of the temperature range of the temperature that makes the metal tube that contacts with pressure instrumentation and conduction oil lower than pressure instrumentation, avoid Yin Gaowen to cause the inaccurate problem of pressure measurement to the damage of pressure instrumentation.
High temperature described in the utility model refers to 300 ℃ of following temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of high temperature pressure vessel pressure tester;
Fig. 2 is the front view of high temperature pressure vessel pressure tester.
Being labeled as in accompanying drawing: 1-strain box, 2-metal tube, 3-pressure instrumentation, 4-cooling device, 5-heat eliminating medium entrance, the outlet of 6-heat eliminating medium.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
The utility model principle of work: this high temperature pressure vessel pressure tester is set on the pressure vessel in serviceability temperature below 300 ℃, in the time that the pressure of pressure vessel inside changes, strain box 1 can be along with the variation of pressure certain elastic deformation occurs and produces certain stress, under the effect of this stress, make to produce certain pressure in the conduction oil in metal tube 2, pressure instrumentation 3 can be measured the pressure in high temperature pressure vessel indirectly by gaging pressure.Wherein cooling device 4 can be passed to by heat eliminating medium absorption pressure container the heat of metal tube 2 and conduction oil, avoids causing the inaccurate problem of pressure instrumentation pressure measurement because of excess Temperature.
