Description
Technical field
This utility model relates to Pull breaking ualve technical field, specifically a kind of low-temperature breakaway valve.
Background technology
In fluid foods cargo handling process, often run into the situation that the position of fluid reservoir changes, such as
Unload fluid foods during boats and ships landing pier, be that harbour is motionless, boats and ships rock, the groove tank car handling fluid foods of highway or railway
Time, groove tank car can move, and fluid reservoir is for fixing or mobile.Above-mentioned in the case of these, the pipeline of conveyance fluid material
It is unexpected that situation about rupturing will occur, cause leakage accident.
Pull breaking ualve is also referred to as emergency separating device, can prevent from occurring fluid foods to leak because of pipeline break, mainly break
Valve can disconnect under certain External Force Acting automatically, and the two parts after disconnection are respectively provided with self-sealing function.Existing Pull breaking ualve makes
During with, there are the following problems: existing Pull breaking ualve range of application is narrower, often can only be used alone on hard tube or flexible pipe,
The pipeline of unlike material needs different Pull breaking ualves；The easy stress of existing Pull breaking ualve is unstable uniformly, be susceptible to separate by mistake and
Cause the accident, make safety equipment become potential safety hazard on the contrary；The recycling operation of existing Pull breaking ualve is relatively complicated, and work is strong
Degree is big, wastes time and energy.
Utility model content
This utility model technical issues that need to address are to provide a kind of low-temperature breakaway valve, improve the sealing of Pull breaking ualve
Can, reduce flow resistance, make breakaway value stabilization, be swift in motion, and after disconnection, restructuring is convenient.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
A kind of low-temperature breakaway valve, is made up of half valve body docking of two symmetrical configuration, and described half valve body includes that one end is arranged
The half valve body overcoat that abutted flange, the other end are connected by steel ball retaining mechanism and half valve body inner sleeve, described half valve body inner sleeve
Arranging flap with in the body cavity of half valve body overcoat composition by support, described flap seals with one end of body cavity and coordinates
And spring is set between support and the other end of body cavity, said two half valve body is by abutted flange and runs through two docking
The end phase apical grafting of two flaps when the disconnected pin of cause of flange is connected and docks.
Further improvement is that of technical solutions of the utility model: arrange corresponding on the contact surface of said two flange
Seal groove, arranges spring energy-storage sealing ring I in described seal groove.
Further improvement is that of technical solutions of the utility model: described flap is spindle-type α-Fe2O3 and at flap and valve body
Spring energy-storage sealing ring II is set on the contact surface between inner chamber.
Further improvement is that of technical solutions of the utility model: arrange on described support and the contact surface of body cavity and lead
To sealing shroud.
Further improvement is that of technical solutions of the utility model: described half valve body inner sleeve and the contact jaw of half valve body overcoat
Portion arranges spring energy-storage sealing ring III.
Further improvement is that of technical solutions of the utility model: the quantity causing disconnected pin on described abutted flange is 3.
Owing to have employed technique scheme, the technological progress that this utility model obtains is:
Low-temperature breakaway valve of the present utility model has that good seal performance, flow resistance be little, breakaway value stabilization, be swift in motion and
Recombinating after disconnection the feature such as convenience, safe and reliable easy-maintaining, low-temperature breakaway valve of the present utility model can be used for the low temperature of-196 DEG C
Situation.
Low-temperature breakaway valve of the present utility model is made up of half valve body that two structures are identical.The abutted flange of two and half valve bodies
Caused disconnected pin by 3 to connect, by changing the pull-off force that the shape causing disconnected pin obtains varying in size, when Pull breaking ualve is by disconnected more than causing
When pin presets the outer active force of pull-off force, Pull breaking ualve can automatically disconnect and half valve body at two ends under the effect of spring and flap from
Dynamic closing.The interface of half valve body overcoat and half valve body inner sleeve uses steel ball retaining mechanism to connect, and rotates flexibly, can effectively eliminate because of
The cut-out power that valve is produced by pipeline distortion.Flap uses spindle design, can reduce turbulent flow when pumped (conveying) medium, improves valve
Flow-reduction flow resistance.Valve uses spring energy-storage sealing ring I, spring energy-storage sealing ring II, the sealing of spring energy-storage sealing ring III
Relevant position is sealed by structure, can effectively prevent from sealing because the temperature difference is deformed impact.The pilot seal set of support uses
Elastomeric material, can prevent because the temperature difference is deformed flap action is produced impact.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further details:
A kind of low-temperature breakaway valve of the present utility model, is made up of, for each portion half valve body docking of two symmetrical configuration
Dividing single half valve body, structure is as it is shown in figure 1, particularly as follows: half valve body includes half valve body inner sleeve 3 and half valve body overcoat 4, half valve body
One end of overcoat 4 arranges abutted flange 1, and the other end of half valve body overcoat 4 connects half valve body inner sleeve 3, half valve body inner sleeve 3 and half valve
Being connected by steel ball retaining mechanism 2 between external set 4, steel ball retaining mechanism 2 rotates flexibly, can effectively eliminate because pipeline distorts
The cut-out power that valve is produced.
The body cavity that half valve body inner sleeve 3 of the present utility model and half valve body overcoat 4 are constituted, body cavity is the stream of medium
Circulation passage, arranges flap 6 by support 5 in body cavity, and flap 6 seals with one end of body cavity and coordinates, support 5 and valve
Arranging spring 7 between the other end of intracoelomic cavity, when Pull breaking ualve disconnects, under the effect of spring 7, flap 6 withstands on body cavity
End, prevent liquid outflow, two and half valve bodies are by abutted flange 1 and run through the cause of two abutted flanges 1 pin 11 that breaks and be connected
Connecing, the end phase apical grafting of two flaps 6 during docking, such spring 7 is compressed, and flap 6 will leave the end of body cavity, valve
Just leave gap between lobe 6 and body cavity, be available for liquid medium flow.
Flap 6 of the present utility model is spindle-type α-Fe2O3, can reduce turbulent flow when pumped (conveying) medium, improves valve flow and reduces
Flow resistance.Corresponding seal groove is set on the contact surface of two flanges 1, spring energy-storage sealing ring I 8 is set in seal groove.At valve
Spring energy-storage sealing ring II 9 is set on the contact surface between lobe 6 and body cavity.Connecing of half valve body inner sleeve 3 and half valve body overcoat 4
Contacting end portion arranges spring energy-storage sealing ring III 10.Can effectively prevent from sealing because the temperature difference is deformed impact.Support 5 and body cavity
Contact surface on arrange pilot seal set 5-1.Can prevent because the temperature difference is deformed flap action is produced impact.Abutted flange 1
The break quantity of pin 2 of upper cause is 3.
