Description
Technical field
Not only there is simple in structure, compact, easy for installation, operational safety the utility model is related to a kind of, but also can select not
Isostructural switching valve carries out the inner pressurd vessel safety device of the large-scale low-temperature atmospheric storage tank of reasonable typesetting design, is set with reaching guarantee
The purpose of standby safe and reliable operation.
Background technology
Space division project scene, liquefied natural gas relevant enterprise, or it is related to the occasion of cryogenic liquid purposes, large-scale low-temperature
Storage tank is often its indispensable important composition equipment, is mainly used to store space division product --- cryogenic liquid, such as liquid oxygen, liquid
The products such as nitrogen, liquid argon.Due to the property of cryogenic liquid, the requirement to bunkerage is also relatively high, has both required cold insulation adiabatic,
Loss of refrigeration capacity is prevented, is overcome again due to the variation of environmental factor and the effumability of cryogenic liquid itself and leads to container internal pressure
Power constantly changes, so just seeming increasingly important to the safe design of storage tank, what is especially directly contacted with cryogenic liquid is interior
Container.Previous design is often that structure not enough optimizes, and typesetting is less reasonable, and occupies limited operable sky at the top of equipment
Between.
Invention content
Purpose of design：The shortcoming in background technology is avoided, design is a kind of both to have simple in structure, compact, installation side
Just, operational safety, but can select the switching valve of different structure carry out reasonable typesetting design large-scale low-temperature atmospheric storage tank it is interior
Vessel safety device, to achieve the purpose that ensure equipment safety reliability service.
Design scheme：In order to realize above-mentioned purpose of design.The utility model will take in structure design from inner pressurd vessel top
Portion is drawn, and is connected by flange, fastener and three-way switch valve, while being used and being welded to connect with automatic evacuation component, standard pipe
By welding or flange, fastener, to connect, composition is a set of to be cut by threeway between part, demolition set, breather valve and blow-down pipe
Double breather valves, double demolition sets and a set of automatic emptying device for changing valve to control are in the inner pressurd vessel safety device of one.
Technical solution：A kind of inner pressurd vessel safety device of large-scale low-temperature atmospheric storage tank, including breather valve, demolition set, three
Direction changeover valve Standard fittings, flange, bolt and nut fastener, is taken over, blow-down pipe, automatic evacuation component, takes over from inner pressurd vessel top
Portion is drawn through flange, fastener and three-way switch valve connection and is connect simultaneously with automatic evacuation components welding, Standard fittings, explosion
Between device, breather valve and blow-down pipe by welding or flange, fastener come connect composition it is a set of can by three-way switch valve come
Double breather valves, double demolition sets and a set of automatic emptying device of control are in the inner pressurd vessel safety device of one.
The utility model compared with the background art, when it is compact-sized, integrated level is high；Second is that easy to operate, operational safety
Reliably, the safety and economic operation of storage tank is played and its important role.
Description of the drawings
Fig. 1 is the structural schematic diagram of the inner pressurd vessel safety device of large-scale low-temperature atmospheric storage tank.

Part 9, it is characterized in that：Take over 7 connect from inner pressurd vessel Base top contact with three-way switch valve 3 by flange 5, fastener 6 simultaneously with from
Dynamic emptying component 9 is welded to connect, between Standard fittings 4, demolition set 2, breather valve 1 and blow-down pipe 8 by welding or flange 5,
Fastener 6 connects a set of double breather valves that can be controlled by three-way switch valve 3 of composition, double demolition sets and a set of puts automatically
Sky is installed on integrated inner pressurd vessel safety device.That is, two threeway one end are connected to breather valve 1 respectively, two threeway other ends
Lead to respectively in U-shaped threeway two and connect, in U-shaped threeway in lead to be connected to take over 7, four blow-down pipes 8 respectively with breathing
Valve 1 and demolition set 2 are connected to, and take over 7 is connect by flange 5, fastener 6 with three-way switch valve 3 from inner pressurd vessel Base top contact,
Passed through between Standard fittings 4, demolition set 2, breather valve 1 and blow-down pipe 8 using being welded to connect with automatic evacuation component 9 simultaneously
Welding or flange 5, fastener 6 connect, and form a set of double breather valves that can be controlled by three-way switch valve 3, double explosions fill
It sets with a set of automatic emptying device in the inner pressurd vessel safety device of one.It makes and the mounting process system prior art, herein not
It is described herein.
It is to be understood that：Although above-described embodiment contrasts detailed word to the mentality of designing of the utility model
Description, but these verbal descriptions only describe the simple text of the utility model mentality of designing, rather than new to this practicality
It is new to each fall within this practicality for the limitation of type mentality of designing, any combination, increase or modification without departing from the utility model mentality of designing
