Abstract
A kind of emergency cut-off bottom valve, including valve body (10), valve element (3) and valve seat (4), it is characterised in that:Valve body (10) close to valve flange (2) bottom is provided with emergency cut-off groove (8);The body (9) of the termination of valve body (10) interior drive rod (1) and valve element (3) bottom is slidably matched.Emergency cut-off groove is an annular recess being centered around on valve body outer circumference surface.The body of valve element bottom is located at the center of valve element bottom.When something unexpected happened severs bottom valve, valve body will be broken along emergency cut-off groove this weaker link, and valve flange still with valve seat and link together, still in sealing state.It is slidably matched because the body of drive rod and prominent one section of valve element bottom belongs to, so drive rod is easy to from set in vivo deviate from and come off with a part of valve body, valve element can't be prized, so as to ensure that leaking for liquid particularly dangerous material will not be caused because bottom valve damages.
Description
Technical field
The invention belongs to special car and special purpose vehicle technical field, is related to a kind of emergency cut-off bottom valve, particularly one kind
The emergency cut-off bottom valve of liquid transport tank car.
Background technology
With the continuous improvement to canister liquid hazardous materials transportation car and semitrailer safety requirements, road transport liquid goods
Tank vehicle quick action emergency valve turns into indispensable accessory.However, due to many originals such as production batch, price competitions
Cause, the performance for the quick action emergency valve that national 1,800 Duo Jia manufacturing enterprises use are difficult to reach standard requirement, show and work as
When quick action emergency valve is by abnormal external force, sealing between valve and tank car is by destroying, the failures such as leakage, or valve sheet occurs
Body damage, sealing function is lost, in turn result in the liquid leakage in tank vehicle, trigger serious economic loss and environment dirty
Dye, so this area needs a kind of emergency cut-off bottom valve of petroleum transported car badly at present, to reach the new demand of automobile industry.
The content of the invention
The problem of it is an object of the invention to exist to prior art, solves, there is provided one kind is rational in infrastructure, can prevent
Occur surprisingly severing bottom valve and making the emergency cut-off of the liquid hazardous goods tank vehicle of liquid leakage, road transport of good performance
Bottom valve.
The technical solution of the present invention is:
--- it is provided with emergency cut-off groove on the valve body close to valve flange bottom.
--- the body of the termination of drive rod and valve element bottom is slidably matched in valve body.
The further technical solution of the present invention is:
--- described emergency cut-off groove is an annular recess being centered around on valve body outer circumference surface.
--- the body of described valve element bottom is located at the center of valve element bottom.
Upward sliding sleeve is socketed and is slidably matched with newel downward in flow blocking seat in _ _ _ _ described valve element, valve element it is interior
There is a spring between bottom and the interior top of flow blocking seat.
--- described emergency cut-off groove is the ring-type being centered around on a valve body outer circumference surface arc groove or V-shaped groove.
Compared with prior art, beneficial effect possessed by the present invention is：When emergency cut-off bottom valve is by abnormal external force,
Valve body can be broken at prefabricated emergency cut-off groove, because valve element and valve seat are combined closely, can thus avoid valve and tank
The sealing in workshop by destroy, occur leakage etc. failure.When the valve body of fracture and when being embedded in drive rod therein and dropping together,
Drive rod departs from immediately with pit, so valve element will not be prized, thus valve can be avoided to lose sealing function in itself, and then
The liquid leakage in tank vehicle is caused, triggers serious economic loss and environmental pollution.This emergency cut-off bottom valve completely may be used
To reach the new demand that automobile industry particularly transports liquid tank car.
Brief description of the drawings
Accompanying drawing is the structural representation of one embodiment of the invention.
Embodiment
Referring to accompanying drawing, the present invention is by valve body 10, drive rod 1, valve flange 2, valve element 3, valve seat 4, flow blocking seat 5, sealing ring
6th, spring 7 and emergency cut-off groove 8 are formed, wherein, it is threadedly coupled between valve body 10 and flow blocking seat 5, between valve seat 4 and flow blocking seat 5
And threaded connection, and valve seat 4 is located between valve body 10 and the planar annular of flow blocking seat 5.One valve element 3 is assemblied in flow blocking seat
In 5, the outer circumference surface of valve element 3 is fitted close with the inner peripheral surface of flow blocking seat 5, in the outer circumference surface and flow blocking seat 5 of valve element 3
Sealing ring 6 is additionally provided between periphery.Upward sliding sleeve 11 is socketed and slided with newel 12 downward in flow blocking seat 5 in valve element 3
It is dynamic to coordinate, there is a spring 7 between the interior bottom of valve element 3 and the interior top of flow blocking seat 5.The centre bit of the described bottom of valve element 3 installs
The body 9 of a prominent bottom surface is counted, the top of this body 9 and the drive rod 1 in valve body 10 is also to be slidably matched.
The bottom of valve flange 2 is centered around the emergency cut-off groove 8 of a prefabricated ring-type on the outer circumference surface of valve body 10, this emergency cut-off
Groove 8 can be deep-slotted chip breaker or V-shaped groove, its purpose is to the bottom valve of liquid transport tank car when running into accidental impact valve body 10
It will be broken at urgent eager fault trough 8, while the drive rod 1 in valve body 10 will depart from body 9, can't jack up valve
Core 3, so as to avoid the leakage of liquid.
Under normal circumstances, the immense pressure of spring 7 makes valve element 3 be tightly pressed against on valve seat 4 to form sealing state, and liquid is not
It can be flowed out from valve body.When needing to discharge liquid, only by drive device drive rod 1 need to be moved into jack-up valve element 3 upwards could beat
Drive quick action emergency valve.When something unexpected happened severs valve body 10, valve body 10 will this be weaker along emergency cut-off groove 8
Link at be broken, and valve flange 2 still with valve seat 4 and link together, still in sealing state.Because drive rod 1 is with dashing forward
The body 9 for going out one section of 3 bottom of valve element belongs to and is slidably matched, so drive rod 1 is easy to out of body 9 abjection and with a part of valve
Body 10 comes off, and can't prize valve element 3, so as to ensure that the outer of liquid particularly dangerous material will not be caused because bottom valve damages
Let out.
