Technical field
The present invention relates to a kind of safety-valve of anti-leak, it is dehydrated leakage safety valve particularly to a kind of anti-spherical tank.
Background technology
Oil tank automatic dewatering device has been widely used in petrochemical industry storage tank, instead of artificial dehydration, provides for producing
Very big convenience.But in process of production, a certain amount of moisture in liquefied gas, can be contained.When liquefied petroleum gas is stored in spherical tank
When middle, the water in liquefied gas can be deposited to Spherical Tank it is necessary to discharge in time by automatic or manual dehydration valve.
When dehydration valve failure or out of control when, substantial amounts of liquefied gas can leak in air, leads to environmental pollution, forms safety
Hidden danger, or even cause serious security incident.In recent years, our countries had occurred that many causes were dewatered to the spherical tank liquid leading to
The accident of activating QI leakage, or even there occurs serious blast, cause the dead and wounded and great property loss of many people.
Therefore, no matter whether spherical tank is mounted with automatic dewatering device, and scene does not allow from people, is essentially all manually de-
Water.It is fitted without automatic dewatering device, and during completely using artificial dehydration, in order to ensure safety, the valve of employing is typically all certainly
Dynamic resilience valve: people once looses one's grip, leaves, valve will be automatically switched off, to guarantee safety.Nonetheless, cannot guarantee that definitely
Safety, also waste of manpower.

Specific embodiment
In conjunction with accompanying drawing, the invention will be further described with specific embodiment.
Refering to shown in Fig. 1 and Fig. 2, a kind of anti-spherical tank of the present invention is dehydrated leakage safety valve, comprising:
Main body tank 1, including water inlet, the outlet pipe 12 located at main body tank 1 lower section and the ball float 3 in main body tank 1；Main
Body tank 1 is additionally provided with gas outlet；The drain pipe 6 that water inlet is dehydrated leakage safety valve with anti-spherical tank connects.Outlet pipe 12 for trend is
Down, more past horizontal, more up, more past horizontal, then pipeline down.Water inlet in the middle part of the side wall of main body tank 1, outlet pipe
12 top will be less than the horizontal level of water inlet, and the setting of top is prevented from aqueous reflux；The top of outlet pipe 12
It is higher than the link position of outlet pipe 12 and main body tank 1, prevents water from also not excluding from main body tank 1, ball float 3 is outlet pipe
12 water inlet is blocked.
Escape pipe, escape pipe includes blow-down pipe 111 and the relief tube 112 be responsible for and communicate with supervisor；Set on relief tube 112
There is relief valve 3, the port of export of relief tube 112 is provided with flare line 113；Discharge on blow-down pipe 111 during the external world along gas
Flow direction, is sequentially provided with governor valve 2, atmospheric valve 4 on blow-down pipe 111.
Refering to Fig. 3, governor valve 2 includes the local pipeline section 41 of blow-down pipe 111 and intraluminal located at this local pipeline section 41
Spheroid 42, the caliber of the bottom 411 of local pipeline section 41 big to its upper 412 caliber；The tube chamber of the bottom 411 of local pipeline section 41
Inside it is provided with the filter 43 for spheroid described in support, spheroid 42 is located on filter 43.As shown in Fig. 2 when flow velocity is relatively low, spheroid
Valve element is in the bottom of local pipeline section 41, and when flow velocity is larger, little club rises, and blow-down pipe 111 is blocked.
Governor valve shown in Fig. 3 is a kind of structure for speed limit is described therein, can also be other structures, such as
Little valve on pressure cooker, vapour on one, little valve above just withstands, and just falls down after losing heart.Key is regardless of form
Governor valve, as long as flow one is big, valve just can be shut automatically.
Drain pipe 6 is provided with dehydration valve 5, and dehydration valve 5 is stop valve, anti-spherical tank dehydration leakage safety valve peace of the present invention
After being contained in the dehydration valve of drainage direction.
The application principle of the present invention: when spherical tank 7 is normally dehydrated, water is discharged from dehydration valve 5, after main body tank 1, from outlet pipe
12 discharges.After the water in spherical tank is drained, if dehydration valve failure cannot be closed, water when gas can subsequently be excluded, in main body tank 1
After drained, the effluent pipe mouth of outlet pipe 12 is blocked by ball float.Gas is discharged from governor valve 2.When gas flow rate exceedes setting value,
Governor valve 2 shuts.Certainly, now relief valve 3, atmospheric valve 4 are to close.Gas in spherical tank will not leak in air again.
When needing to be dehydrated again, close dehydration valve 5, open relief valve 3, the gas in main body tank 1 is discharged into flare line.
Pressure drop in main body tank 1, governor valve automatically opens up.Open dehydration valve 5 again, you can to continue to be dehydrated.
Present invention is mainly used for the moisture in liquefied petroleum gas gas storage spherical tank blowdown vessel body.
Using ball float it is ensured that draining not aerofluxuss.After drained water, when gas enters main body tank 1, ball float is automatically stifled by outlet
Live.When the water in main body tank 1 is not also completely exhausted out main body tank 1, water seal lived outlet pipe 12 outlet it is ensured that gas not
Can discharge from outlet pipe.When not having gas to discharge, ball float will not block the effluent pipe mouth of outlet pipe 12 because of deadweight.Gas flow rate surpasses
When crossing setting value, governor valve can be automatically switched off it is ensured that gas does not leak.It is provided with relief valve 3, the gas in main body tank 1 is let out
It is put into low pressure flare pipeline, it is to avoid contaminated air, form potential safety hazard.
The effect of atmospheric valve: the pressure in main body tank must reach normal pressure could normal work.A large amount of when having in main body tank
Liquefied gas when it is impossible to direct emptying is it is necessary to first be discharged into flare line substantial amounts of gas, it is to avoid contaminated air.Only few
Could be vented after amount gas.So when in main body tank, gas is more, except governor valve can cut out blow-down pipe when flow velocity is larger,
Remaining when need the closing of atmospheric valve, realize gas and can not discharge from blow-down pipe, when only gas is less in main body tank, beat
Open atmospheric valve vent gas.
During dehydration, in the event of deflation fault, ball float can be blocked lower outlet, and governor valve can be blocked upper outlet.Need
Dehydration valve 5, atmospheric valve 4 need to first be closed, substantial amounts of gas be released to flare line, the pressure drop in main body tank in dehydration
To the pressure as flare line, about to 0.02-0.03mpa, governor valve 2 can automatically open up, then opens valve atmospheric valve 4,
Residual gas in main body tank is discharged, and pressure returns to normal pressure.Water in outlet pipe 12 is back to main body tank, the ball float in main body tank
Just can float, then just can be normally carried out dewatering work.
The invention is not limited in above-mentioned embodiment, if to the various changes or modification of the present invention without departing from the present invention
Spirit and scope, if these are changed and within the scope of modification belongs to claim and the equivalent technologies of the present invention, then this
Bright it is also intended to comprise these and changes and change.
