Description
Technical field
This utility model relates to Pull breaking ualve technical field, specifically a kind of disconnected urgent Pull breaking ualve of formula of cause.
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 the disconnected urgent Pull breaking ualve of formula of a kind of cause, improve the close of Pull breaking ualve
Sealing property, reduces flow resistance, makes breakaway value stabilization, is swift in motion, and after disconnection, restructuring is convenient.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
The disconnected urgent Pull breaking ualve of formula of a kind of cause, is made up of half valve body docking of two symmetrical configuration, and described half valve body includes one
End arranges abutted flange, half valve body leading portion that the other end is connected by bolt and half valve body back segment, described half valve body back segment with
Arranging flap by support in the body cavity that half valve body leading portion is constituted, one end of described flap seals with one end of body cavity
Coordinate and the other end of flap arranges the guide post matched with the pilot hole on support, the guiding between described flap and support
Arranging spring on bar, said two half valve body is by abutted flange and runs through the cause of two abutted flanges pin that breaks and is connected and docks
Time two flaps end phase apical grafting.
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 support is three width formula designs.
Further improvement is that of technical solutions of the utility model: described flap is spindle-type α-Fe2O3 and at flap and valve body
On contact surface between inner chamber, polytetrafluoroethylene sealing gasket is set.
Further improvement is that of technical solutions of the utility model: described half valve body back segment and the contact surface of half valve body leading portion
On corresponding seal groove is set, spring energy-storage sealing ring II is set in described seal groove.
Further improvement is that of technical solutions of the utility model: the afterbody of described half valve body back segment arranges bump joint.
Further improvement is that of technical solutions of the utility model: the quantity causing disconnected pin on described abutted flange is 3 ~ 6.
Owing to have employed technique scheme, the technological progress that this utility model obtains is:
Cause of the present utility model break the urgent Pull breaking ualve of formula have that good seal performance, flow resistance be little, breakaway value stabilization, action fast
Speed and the feature such as convenience, safe and reliable easy-maintaining of recombinating after disconnecting.
The cause of the present utility model urgent Pull breaking ualve of formula that breaks is made up of half valve body that two structures are identical.Two and half valve bodies right
Acting flange is caused disconnected pin by 3 ~ 6 and connects, by changing the pull-off force that the shape causing disconnected pin obtains varying in size, when Pull breaking ualve is subject to
More than when causing outer active force that disconnected pin presets pull-off force, Pull breaking ualve can disconnect automatically and half valve body at two ends is at spring and flap
The lower self-closed of effect.The interface of half valve body back segment and half valve body leading portion uses split-type design, facilitates the processing of whole valve body
And assemble.Flap uses spindle design, can reduce turbulent flow when pumped (conveying) medium, improves valve flow and reduces flow resistance.Valve is adopted
By polytetrafluoroethylene sealing gasket, spring energy-storage sealing ring I, the sealing structure of spring energy-storage sealing ring II, relevant position is carried out close
Envelope, can effectively prevent from sealing because the temperature difference is deformed impact.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further details:
The disconnected urgent Pull breaking ualve of formula of a kind of cause of the present utility model, is made up of half valve body docking of two symmetrical configuration, for
Every a part of single half valve body, particularly as follows: half valve body includes half valve body back segment 3 and half valve body leading portion 4, half valve body leading portion 4
One end arranges abutted flange 1, and the other end of half valve body leading portion 4 connects half valve body back segment 3, half valve body back segment 3 and half valve body leading portion 4
Between be connected by bolt 2.
The body cavity that half valve body back segment 3 of the present utility model and half valve body leading portion 4 are constituted, body cavity is the stream of medium
