Description
Technical field
It the utility model is related 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 store such as crude oil,
Gasoline or kerosene etc. have volatile oil product, can be divided into by the characteristics of oil tank residual oil in tank：Fixed roof tank, floating roof storage
Three kinds of tank, spherical storage tank patterns, and floating roof tank is divided into External floating roof tank, internal floating roof tank.Because the maximization of storage tank is (high
Volume) higher requirement is proposed to tank designs, manufacture, installation, floating roof is made of metal material, floats over liquid table
Closure on face.Floating roof can float with the floating of liquid surface, and when liquid level is down to certain altitude, the pillar in floating roof connects
Tank bottom is touched, 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,
Automatic ventilation valve automatically turns on, and air, which enters in floating plate, enables oil product in tank to be extracted.Conversely, when floating roof is in floating state
When, automatic ventilation valve is closed automatically.
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 with bonnet located at valve body and being connected, and floating roof is in holding state, and valve rod jacks up bonnet, this spline structure it is automatic
Following defect be present in breather valve：After bonnet jacks 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 can not seal, if storage tank still needs to keep the state within a period of time, it will cause easily to wave
Send out oil product evaporating loss, waste of resource.
Utility model content
In view of the deficienciess of the prior art, the utility model provides a kind of automatic ventilation valve of height-adjustable, this is certainly
Dynamic breather valve is provided with the sleeve for offering positioning hole, by the height of regulating valve stem, changes automatic ventilation valve and storage tank bottom plate
Distance, the evaporating loss of oil product is on the one hand effectively reduced, on the other hand also without prejudice to maintenance and inspection.
In order to achieve the above object, the technical scheme that the utility model is taken：
The automatic ventilation valve of height-adjustable, including valve body, the bonnet located at top end of the valve body and the valve being sheathed in valve body
Bar, the top of the bonnet are provided with sleeve, and vertically direction is provided with several positioning holes to the sleeve pipe, and the valve rod runs through bonnet
It is outer and be tightly connected by the upper end of sealing shroud and sleeve pipe to extend to sleeve pipe afterwards, be further opened with the valve rod one with it is described fixed
The pin-and-hole that position Kong Junke is connected.
As optimal technical scheme, in order to effectively reduce oil product evaporating loss, while can provide operating space without prejudice to
Storage tank maintenance and inspection, the positioning 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 transported, avoid manually carrying, reduce work
Power, practicality is improved, the top of the valve rod is provided with a cover plate, and the cover plate is provided with a hanger.
Compared with prior art, the utility model has the advantage that：
1st, the sleeve pipe for opening up positioning hole is provided with bonnet, by regulating valve stem and the position of sleeve pipe connection, to realize certainly
The change of dynamic breather valve and storage tank bottom plate, on the one hand effectively reduces the evaporating loss of oil product, avoids the wasting of resources, on the other hand
Also without prejudice to maintenance and inspection.
2nd, positioning hole is provided with 4, and the setting height(from bottom) in lowest positioned hole is 1.2m, further reduces oil evaporation damage
Consumption, while sufficient operating space can be provided, without prejudice to storage tank maintenance and inspection.
3rd, the top of valve rod is provided with a cover plate, and the cover plate is provided with a hanger, make automatic ventilation valve be easily installed and
Transport, avoids manually carrying, and reduces labour, and practicality is good.

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
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, positioning hole, 6, sealing shroud, 7, cover plate, 8, hanger,
9th, split pin, 10, bearing pin.
Embodiment
A kind of specific embodiment of the utility model, the automatic ventilation valve of height-adjustable, bag are proposed as depicted in figs. 1 and 2
The valve body 1 being welded 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 are included, the bonnet 2
Top is provided with a vertically arranged sleeve pipe 4, and vertically direction is provided with several positioning holes 5 to the sleeve pipe 4, and the valve rod 3 runs through valve
It is outer and be tightly connected by the upper end of sealing shroud 6 and sleeve pipe 4 that sleeve pipe 4 is extended to after lid 1, be further opened with the valve rod 3 one with
