Abstract
The invention provides an ultralow temperature vacuum metal hose dedicated to the petrochemical industry, relating to the field of petrochemical equipment, in particular to an ultralow temperature vacuum metal hose dedicated to the petrochemical industry. The vacuum metal hose comprises an outer layer protective stainless steel soft net layer (1), an outer layer metal hose layer (2), a support bracket (3), a stainless steel soft net layer (4) for inner layer pressure-bearing, an inner layer metal hose layer (5), a vacuum packed layer (6), a vacuum extractor (7), a valve switch (8), a permanent secondary seal (9), a connecting flange (10). In the invention, a vacuum layer is formed by pumping out air between an outer pipe wall and inner pipe wall of the metal pipe, filler is added to the vacuum layer, stainless steel metal soft nets are respectively arranged at the inner layer and outer layer of the metal pipe, thus ensuring safety of petrochemical products in the process of pipeline transportation.
Description
Technical field:
The present invention relates to field of petrochemical industrial, especially relate to a kind of ultra low temperature vacuum metal hose special for petrifaction.
Background technique:
Present society more and more be unable to do without the energy, rely on the energy, professional conveyance conduit as petrochemical industry, pipeline in the past is when carrying transfusion nitrogen, because the temperature of liquid nitrogen is very low, as the conveyance conduit of metal, at every moment bearing low temperature, metallic conduit is gone wrong, also shortened the life-span of metal delivering pipe, thus covert increase cost.
Summary of the invention:
The purpose of this invention is to provide a kind of ultra low temperature vacuum metal hose special for petrifaction, it can effectively solve the existing problem of background technique, its evacuate air between the internal and external layer tube wall of metallic conduit forms vacuum layer, in vacuum layer, add packing, the soft net of stainless steel metal all is installed on the internal and external layer of metallic conduit, utilize the vacuum layer isolated temperature, prolonged the working life of pipeline by packing and the soft net of stainless steel metal, cut down the consumption of energy, guaranteed that petroleum chemicals are in the pipeline transport process safe.
Be achieved by the following technical programs in order to solve the existing problem the present invention of background technique, it comprises outer layer protection stainless steel soft stratum reticulare 1, outer layer metal hose layer 2, supporting frame 3, internal layer pressure-bearing stainless steel soft stratum reticulare 4, inner layer metal hose layer 5, vacuum packed layer 6, vacuum pumping device 7, valve switch 8, permanent secondary seal 9, adpting flange 10, outer layer protection stainless steel soft stratum reticulare 1 is installed in outside the outer layer metal hose layer 2, the internal layer pressure-bearing is installed in outside the inner layer metal hose layer 5 with stainless steel soft stratum reticulare 4, supporting frame 3 is installed in the vacuum packed layer 6, radius of turn according to pipeline evenly is interrupted distribution, and install firm, vacuum pumping device 7 is installed on the end pipe of outer layer metal hose layer 2, design has valve switch 8 on the vacuum pumping device 7, valve switch 8 is provided with permanent secondary seal 9, and the two ends that adpting flange 10 is installed in metallic hose link to each other with equipment; The present invention utilizes evacuate air formation vacuum layer between the internal and external layer tube wall of metallic conduit, in vacuum layer, add packing, the soft net of stainless steel metal all is installed on the internal and external layer of metallic conduit, utilize the vacuum layer isolated temperature, prolonged the working life of pipeline by packing and the soft net of stainless steel metal, cut down the consumption of energy, guaranteed that petroleum chemicals are in the pipeline transport process safe.
Description of drawings:
Fig. 1 is a structural representation of the present invention; Fig. 2 A-A sectional view of the present invention.
Embodiment:
As Fig. 1, shown in 2, it comprises outer layer protection stainless steel soft stratum reticulare 1, outer layer metal hose layer 2, supporting frame 3, internal layer pressure-bearing stainless steel soft stratum reticulare 4, inner layer metal hose layer 5, vacuum packed layer 6, vacuum pumping device 7, valve switch 8, permanent secondary seal 9, adpting flange 10, outer layer protection stainless steel soft stratum reticulare 1 is installed in outside the outer layer metal hose layer 2, the internal layer pressure-bearing is installed in outside the inner layer metal hose layer 5 with stainless steel soft stratum reticulare 4, supporting frame 3 is installed in the vacuum packed layer 6, radius of turn according to pipeline evenly is interrupted distribution, and install firm, vacuum pumping device 7 is installed on the end pipe of outer layer metal hose layer 2, design has valve switch 8 on the vacuum pumping device 7, valve switch 8 is provided with permanent secondary seal 9, and the two ends that adpting flange 10 is installed in metallic hose link to each other with equipment; This embodiment is utilized evacuate air formation vacuum layer between the internal and external layer tube wall of metallic conduit, in vacuum layer, add packing, the soft net of stainless steel metal all is installed on the internal and external layer of metallic conduit, utilize the vacuum layer isolated temperature, prolonged the working life of pipeline by packing and the soft net of stainless steel metal, cut down the consumption of energy, guaranteed that petroleum chemicals are in the pipeline transport process safe.
In this embodiment by on internal and external layer metallic hose layer, having increased the stainless steel soft stratum reticulare; metallic hose is played the effect of protection and pressure-bearing; between internal and external layer metallic hose layer, utilize the switch of valve to find time to make it to form vacuum between the inner and outer pipes layer; guaranteed the obstruct of temperature; and for relative fixed inner layer metal hose layer; used at the vacuum packed layer and set up supporting frame; fixing inner layer metal hose layer so just; add aluminium foil layer and asbestos layer etc. at the vacuum packed layer in addition and fill out fair thing, further intercept the transmission and the protection inner layer metal hose layer of temperature.
In use, at first the air of inside and outside metallic hose layer is found time to form vacuum, then valve switch is shut by valve, between metallic hose and equipment, connect in addition, be beneficial to the installation of metallic hose by flange, also be beneficial to transportation, simplify the construction formality, increase work efficiency.
