Art steps into field test and industrial applications stage, and underwater remote-control Work robot operating water depth is underwater oily up to 4 000m
Gas field development mode becomes increasingly abundant, using the record fast refresh of the depth of water, subsea fields tieback distance.From several meters of the depth of water to number
Km, from marine large oil and gas fields to marginal field, from the North Sea, the Gulf of Mexico to Brazil so that China's eastern South China Sea all
There are many successful stories.The oil gas field depth of water of current application subsea production system exploitation is recorded as Gulf of Mexico Peidido
Mesh, 2 943m of maximum water depth；The full subsea production system development of fields of application and the seabed multiphase delivery pipe by 143km simultaneously
The direct tieback in road has become a reality in the gas field Norway Si Nuohei to land terminal.Subsea production system is with becoming economical and efficient
Develop one of the important technical in deep water hydrocarbon field and marine marginal field.
Petrol resources exploitation turns to ocean from land.Preceding sea turns to deep-sea and has become inexorable trend, Offshore Engineering equipment
As one of high-end equipment manufacture emphasis.Underwater gate valve is applied to adopt defeated well head and subsea production tree under water.It is used with traditional land
The environment of gate valve difference seawater is special, the corrosion such as seawater and the environmental pressure that generates with sea water advanced increase, right
Load performance, corrosion resistant performance, sealing performance, action performance, service life and maintenance period of deep-sea gate valve etc. have higher
Requirement.
Existing underwater gate valve is processed " guidance tape " on valve body, is processed on valve body to guarantee flashboard vertical shift
The difficulty of guidance tape is higher, and is prone to wear out, and cannot achieve using traditional guiding band structure body cavity and does special corrosion resistant
Or cure process, the service life decline of valve seat is in turn resulted in, long term wear leads to the problem of easily leaking out.
Summary of the invention
The utility model is to solve technical problem present in well-known technique and provide a kind of with flashboard guide function, energy
Enough realize on-bne repair, the underwater flat gate valve flashboard guiding mechanism for improving overhaul efficiency, reducing the cost of overhaul.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique:
A kind of underwater flat gate valve flashboard guiding mechanism, flashboard guiding mechanism are removably mounted at the valve seat of flat gate valve
On, the valve seat is mounted on valve body；It is characterized by: the flashboard guiding mechanism includes two identical in mirror image
Guide plate, the guide plate includes guide plate ontology, the guide plate ontology be equipped with valve seat be equipped with centre bore, leading
Flanging is equipped with to two sides of plate ontology to same direction；Two guide plates in mirror symmetry enclose a guiding and move with valve plate
The dynamic consistent guide space in direction；The flashboard described in guide space and guide plate medial surface body contacts, which are formed, to be sealed.
The utility model can also adopt the following technical scheme that
The center of the centre bore is located at position top in the middle part of guide plate ontology, the guiding of valve seat top guide plate
Stroke is less than the guiding stroke of valve seat lower guide plates.
The guide plate with a thickness of 5~10mm.
The height of the flanging is 5~8mm.
It is clearance fit that the centre bore and valve seat, which are equipped with, and clearance fit amount is H10/d10.
The utility model has the advantages and positive effects of: the utility model by adopting the above technical scheme, flashboard and valve
Be provided with detachable guide plate between seat, can effectively reduce valve body guidance tape processing cumbersome process in this way, it can be achieved that online replacement with
Maintenance prevents flashboard from generating offset deviation in longitudinal movement, guarantees product hermeticity energy.With conventional panel gate valve body
Processing " guidance tape " is compared, this detachable guide board structure can process the difficulty of guidance tape and detachable guide plate to avoid valve body
Replacement easy to disassemble can carry out on-line maintenance, while also avoid the cumbersome process of valve body processing guidance tape, reduce processing cost,
Convenient online dismounting and maintenance, solve that conventional panel gate valve structure such as body cavity need to do special corrosion resistant or cure process band is led
The problem of cannot achieve to band structure.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is guide board structure schematic diagram；
Fig. 3 is the utility model usage state diagram.
In figure: 1, valve seat；2, flashboard guiding mechanism；2-1, guide plate；2-10, guide plate ontology；2-11, centre bore；2-
