Abstract
The invention discloses a temperature measuring device for a cryogenic container, belongs to temperature measuring devices, and in particular to the temperature measuring device for measuring the inner temperature of the cryogenic container. The temperature measuring device for the cryogenic container is structurally composed of a liner, a shell and a middle heat insulating layer, wherein a hollow temperature tube with one closed end is welded to the liner, axes of an inner hole of a temperature measuring seat which is fixed on the shell and an inner hole of the temperature tube are in the same straight line, the temperature tube is connected with the temperature measuring seat through a stainless steel expansion joint, and a thermocouple is installed inside a central hole of the temperature measuring seat. The temperature measuring device for the cryogenic container has the advantages of being capable of providing a device for directly measuring the temperature of inner medium inside the cryogenic container, capable of being used in the cryogenic container where the temperature of the inner medium needs measuring and capable of resolving the problem that the inner temperature of the cryogenic container can not be measured.
Description
Technical field
The invention belongs to temperature measuring equipment, especially for the temperature measuring equipment of measuring the deep cooling container inside temperature.
Background technique
Because the insulation heat-insulating property of deep cooling container is excellent, is used for storing the media such as liquid oxygen, liquid nitrogen, liquid argon always.Because medium temperature is usually between-160～-196 ℃, so the direct true temperature of measuring media always.Because the interior medium temperature of inner bag is lower, interlayer is that vacuum state, shell are ambient temperature outward, so deep cooling container never can directly be measured the structure practice of temperature.
Needs with economic development, now a lot of chemical industry producers also store the media such as liquefied carbon dioxide, liquefied ethylene, LNG Liquefied natural gas with the vacuum insulation storage tank, their temperature is generally at-30～-120 ℃, because saturation vapour pressure is larger, so the true temperature in the time of need to a kind ofly installing direct measuring media storage.
Summary of the invention
Can't measure the deficiency of inside temperature in order to solve deep cooling container, the purpose of this invention is to provide a kind of deep cooling container temperature measuring equipment.This device can be measured the temperature of deep cooling container inside easily.
Technological scheme of the present invention is, a kind of deep cooling container temperature measuring equipment, it is characterized in that: the hollow temperature measuring tube that welds end sealing at the inner bag of the deep cooling container that is formed by inner bag, shell and middle heat insulation layer, the axis that is fixed on the endoporus of the endoporus of the thermometric seat on the shell and temperature measuring tube is same straight line, be connected by stainless steel expansion joint between temperature measuring tube and the thermometric seat, the installation of TC is in the center hole of thermometric seat.
Sleeve pipe is followed in the outside weld of described thermometric seat, and sleeve pipe welds together with the stiffening plate that is welded on the shell.
Temperature measuring tube of the present invention passes inner bag and gos deep in the medium, guarantees that temperature that resistance wire measures is as far as possible near the true temperature of medium.Between temperature measuring tube and thermometric seat, installed, according to the temperature difference and the pressure environment of the temperature of medium (about-100 ℃ approximately) and ambient temperature (about 0～50 ℃), as calculated, design, the stainless steel installed expand and can guarantee in thermometric that stablizing of structure do not reveal.And can effectively offset the expansion that the temperature difference causes, avoid the injury of weld.The structures such as sleeve pipe, stiffening plate are adopted in thermometric seat and outer courage joint, reduce step by step the leakage of heat.Thermal resistor can be directly installed on the temperature seat, carries out the measurement of medium temperature in the tank, and measurement result can on-the-spot be indicated, and also can be converted to the resistance signal teletransmission to control centre, so that Real-Time Monitoring.
The invention has the beneficial effects as follows provides a kind of device that can directly measure deep cooling container interior media temperature, can use in needs are measured the deep cooling container of interior media temperature, has solved the difficult problem that deep cooling container can't be measured inside temperature.
