Description
Technical field
The present invention relates to the annex on floating roof tank, and in particular to a kind of automatic ventilation valve of height-adjustable.
Background technology
Storage tank is the visual plant in oil-gas gathering and transportation and storing and transporting system, with national crude oil strategic reserves and energy security
Need, the positive maximization development of crude oil storage tank, its capacity is up to 15 × 104m3.Storage tank be generally used for storage such as crude oil,
Gasoline or kerosene etc. have volatile oil product, can be divided into the characteristics of by oil tank residual oil in tank：Fixed roof tank, floating roof storage
Tank, three kinds of patterns of spherical storage tank, and floating roof tank is divided into External floating roof tank, internal floating roof tank.Because the maximization of storage tank is (high
Volume) requirement higher is proposed to tank designs, manufacture, installation, floating roof is made up of metal material, floats over liquid surface
On closure.Floating roof can float with the floating of liquid surface, when liquid level is down to certain altitude, the column contacts in floating roof
Tank bottom, so as to support floating roof to prevent to decline.Automatic ventilation valve is equipped with outer floating roof, when floating roof is in holding state, from
Dynamic breather valve is automatically turned on, and air is into enabling oil product in tank to be extracted in floating plate.Conversely, when floating roof is in floating state,
Automatic ventilation valve is automatically switched off.
Existing automatic ventilation valve is general as shown in figure 3, mainly including valve body, valve rod, bonnet.Bonnet is located at valve body top
Portion, valve stem sleeve located at valve body and be connected with bonnet, floating roof in holding state, valve rod by bonnet jack-up, this spline structure it is automatic
There is following defect in breather valve：After bonnet jack-up, the position of valve rod is fixed, and now the height of automatic ventilation valve is higher than floating
The height on top, i.e. oil product surface upper end cannot be sealed, if storage tank still needs to keep the state within a period of time, it will cause easily to wave
Hair oil product evaporating loss, waste of resource.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides a kind of automatic ventilation valve of height-adjustable, and this is automatic logical
Air valve is provided with the sleeve for offering location hole, by the height of regulating valve stem, change automatic ventilation valve and storage tank bottom plate away from
From on the one hand effectively reducing the evaporating loss of oil product, on the other hand also without prejudice to maintenance and inspection.
In order to achieve the above object, the technical scheme that the present invention takes：
The automatic ventilation valve of height-adjustable, including valve body, the bonnet located at top end of the valve body and the valve that is sheathed in valve body
Bar, sleeve is provided with above the bonnet, and vertically direction is provided with several location holes to the sleeve pipe, and the valve rod runs through bonnet
Extend to afterwards outside sleeve pipe and be tightly connected with the upper end of sleeve pipe by sealing shroud, one is further opened with the valve rod fixed with described
The pin-and-hole that position Kong Junke is connected.
As optimal technical scheme, in order to be effectively reduced oil product evaporating loss, while operating space without prejudice to can be provided
Storage tank maintenance and inspection, the location hole is provided with 4, and the setting height(from bottom) in lowest positioned hole is 1.2m.
As optimal technical scheme, in order that automatic ventilation valve is easily installed and transports, it is to avoid a dead lift, work is reduced
Power, improves practicality, and a cover plate is provided with above the valve rod, and the cover plate is provided with a hanger.
Compared with prior art, the device have the advantages that：
1st, the sleeve pipe for opening up location hole is provided with bonnet, is realized by the position of regulating valve stem and sleeve pipe connection certainly
Dynamic breather valve and the change of storage tank bottom plate, on the one hand effectively reduce the evaporating loss of oil product, it is to avoid the wasting of resources, on the other hand
Also without prejudice to maintenance and inspection.
2nd, location hole is provided with 4, and the setting height(from bottom) in lowest positioned hole is 1.2m, further reduces oil evaporation and damages
Consumption, while sufficient operating space can be provided, without prejudice to storage tank maintenance and inspection.
3rd, a cover plate is provided with above valve rod, and the cover plate is provided with a hanger, make automatic ventilation valve be easily installed and
Transport, it is to avoid a dead lift, reduces labour, and practicality is good.
Brief description of the drawings
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the invention；
Fig. 2 is valve rod and sleeve pipe connection schematic diagram；
Fig. 3 is the structural representation of existing automatic ventilation valve；
Drawing reference numeral：1st, valve body, 2, bonnet, 3, valve rod, 4, sleeve pipe, 5, location hole, 6, sealing shroud, 7, cover plate, 8, hanger,
9th, split pin, 10, bearing pin.
Specific embodiment
A kind of specific embodiment of the invention, the automatic ventilation valve of height-adjustable, including weldering are proposed as depicted in figs. 1 and 2
The valve body 1 that is connected in floating roof, the bonnet 2 located at the top of valve body 1 and the valve rod 3 being sheathed in valve body 1, the top of the bonnet 2
A vertically arranged sleeve pipe 4 is provided with, vertically direction is provided with several location holes 5 to the sleeve pipe 4, and the valve rod 3 is after bonnet 1
Extend to sleeve pipe 4 outer and be tightly connected with the upper end of sleeve pipe 4 by sealing shroud 6, be further opened with the valve rod 1 one with it is described
The pin-and-hole that location hole 5 can be connected, pin-and-hole is fixedly connected with the location hole 5 by split pin 9, bearing pin 10.
The location hole 5 is provided with 4, and the setting height(from bottom) in lowest positioned hole 5 is 1.2m, between adjacent positioned hole 5
Distance combines oil product storage situation and frequency of maintenance is rationally set, and the general setting height(from bottom) of pillar in floating roof is not less than 1.8m,
In order to reduce oil product evaporating loss as far as possible, the setting height(from bottom) in lowest positioned hole 5 is 1.2m, while it is empty to provide sufficient operation
Between, the maintenance and inspection of without prejudice to storage tank.
The top of the valve rod 3 is provided with a cover plate 7, and the cover plate 7 is provided with a hanger 8, and the present embodiment sets described
Valve rod 3 is that, by being welded to connect, the hanger 8 can hang on lifting with the hanger 8 with the cover plate 7, the cover plate 7
In equipment, automatic ventilation valve is easily installed and is transported, it is to avoid a dead lift, reduce labour, practicality is high.
When the present invention is used：This automatic ventilation valve is arranged in the floating roof of External floating roof tank, when floating roof is in floating shape
During state, this automatic ventilation valve is closed, artificial regulating valve stem 3 up and down, when floating roof is in holding state, the meeting of valve rod 3
By the jack-up of bonnet 2, if pin-and-hole on valve rod 3 is connected with the location hole 5 on top on sleeve pipe 4, automatic ventilation valve and storage tank
The distance of base plate is maximum, is easy to maintenance and inspection；If the pin-and-hole on valve rod 3 is connected with the location hole 5 of bottom on sleeve pipe 4,
The distance of automatic ventilation valve and storage tank bottom plate is minimum, so that the very big evaporating loss of oil product.
Certainly, the preferred embodiments of the disclosure is described in detail with reference to accompanying drawing simply above, not with this
Practical range of the invention is limited, the equivalence changes that all principles under this invention, construction and structure are made all should be covered by this
In the protection domain of invention.
