Description
Technical field:
The utility model is suitable for the engineerings such as electric heating and oil field gas injection exploitation, and especially a kind of pair of heavy crude heat extraction and high temperature are high
The high temperature and pressure well head thermal recovery valve special valve that pressure steam is controlled.
Background technique:
With the high speed development of the national economy in China.The electric power needed and the growth of crude oil at double, for controlling steam
The valve of pipeline is more and more, while increasingly more viscous crude fields is by development & construction, since viscous crude density is big and hardened,
The steam of high temperature and pressure need to be injected to dissolve viscous crude, while the corrosive substances such as sulfide in crude oil content is high.In well head
Valve just plays key effect.The steam of valve injection high temperature and pressure is first passed through to dissolve viscous crude.High temperature and pressure well head thermal recovery valve
Exactly specially manufacture and design for this operating condition situation of heavy crude heat extraction and the defeated vapour oil recovery pipeline of high temperature and pressure.
The steam pipework of traditional viscous crude uses shut-off valve, and flow resistance is big, and operating force is away from big, inconvenient for operation, inefficiency.
Entire pipeline is very long, extremely inconvenient, while equipment cost becomes larger.Flashboard is resistance to high and long-term due to not can solve sealing ring
Use the compensation after abrasion.Service life is extremely short, and new valve was just needed replacing less than 10 months, causes greatly to waste, with
And influence and a large amount of manpower of needs stopped work when replacement to production.
Utility model content:
The utility model aim is to propose a kind of high temperature and pressure well head thermal recovery valve special valve, has good airproof performance, flashboard
Lubricating condition is good, and open and close is light, and solves the compensation after the resistance to high abrasion with long-time service of sealing ring.
Technical solutions of the utility model are that a kind of high temperature and pressure well head thermal recovery valve, including valve body, flashboard, valve body lower portion are (interior
Portion) fluid channel and the enterprising outlet of valve body, valve inner fluid channel be equipped with a pair of parallel sealing ring insertion valve body 1 and
Perpendicular to fluid channel；Flashboard is embedded in this pair of parallel sealing ring, and flashboard is in valve body fluid passage, that is, a pair of seal rings
It moves up and down, ram movement is controlled by the valve rod and handwheel fixed with flashboard；The upper and lower movement position of valve plate corresponds to the conducting of valve
With cut-off (part cut-off is until whole cut-offs)；The top of flashboard and valve rod are equipped with sealing element on valve body；Every sealing ring
First plane be bonded with valve plate, the inlet and outlet center line on sealing ring and valve body is on the same line.
Second plane of sealing ring posts enhancing soft graphite ring in the installation site of valve body.
The combination sealing filler and gland of package valve rod are equipped in valve rod upper position installation connector sleeve, connector sleeve.
It is additionally provided with bracket, bearing above connector sleeve, valve rod rotates in the bearing of package, and is located at combination sealing filler
Top.
The course of work: as shown, when valve rod moves upwards, valve rod drives flashboard to be lifted up, and opens entire
Steam and the oil recovery of high temperature and pressure are injected in channel.When valve rod moves downward, and reaches rest position, entire channel is closed,
Terminate the steam injection of high temperature and pressure and recovers the oil.
The utility model has the advantages that the flashboard of the utility model uses slab construction, no flow resistance both can be recovered the oil or be can be injected
High temperature and high pressure steam.Valve switch and laborsaving is facilitated using bearing driving device.Ram seal is special using enhancing soft graphite
Structure, the breakable problem of the soft graphite of solving over, guarantees sealing performance under the conditions of high temperature and high pressure condition.Filler is adopted
With composite structure, guarantee the reliability of sealing.Keep sealing surface corrosion-resistant using different types of carbide reactor welding technology, resistance to punching
It hits, guarantees the service life of valve.
Detailed description of the invention
Fig. 1 is the utility model cross section structure schematic diagram.
Specific embodiment
As shown, valve body 1, flashboard 2, sealing ring 3, the special soft graphite 4 of enhancing, positioning screw 5, gasket seal 6, company
Female connector 7, combination sealing filler 8 mark closely screw 9, gland 10, bracket 11, bearing 12, lubricating cup 13, mark closely screw 14, positioning
Screw 15, valve stem nut 16, handwheel 17, valve rod 18, valve bonnet 19.
As shown, high temperature and pressure well head thermal recovery valve, 10 section of valve inner valve body fluid passage is equipped with a pair of of gold
The sealing ring 3 of category is connected in valve body, with the inlet and outlet of valve, and spool 3 is in valve body fluid passage, that is, spool chamber fortune up and down
Dynamic, flashboard 2, which is cut in this pair of parallel sealing ring 3, can be truncated runner i.e. for valve cut-off or conducting, and flashboard is in valve body
Fluid channel, that is, a pair of seal rings moves up and down, and controls ram movement by the valve rod and handwheel fixed with flashboard；Valve plate is transported above and below
Dynamic position corresponds to the conducting and cut-off of valve (part cut-off is until whole cut-offs)；A plane and valve plate for every sealing ring is pasted
It closes, on the same line, and another plane of sealing ring is in the installation of valve body for the inlet and outlet center line on sealing ring and valve body
Post enhancing soft graphite ring 4 in position.Top valve rod upper position installation connector sleeve 7, the connector sleeve of flashboard are interior to be equipped with package valve
The combination sealing filler 8 and gland 10 of bar.
It goes back that valve body is additionally provided with bearing 12, bearing 12 also wraps up valve rod above connector sleeve, and is located at the upper of combination sealing filler
Side.Filler uses composite structure, guarantees the reliability of sealing.
Flashboard uses the hardened structure of plate seal, between the sealing ring 3 of a pair of parallel metal.The sealing of parallel metal
The center line of ring and the inlet and outlet of valve use straight through flow channel type structure, substantially without flow resistance on a center line.Using axis
Bearing apparatus facilitates valve switch and laborsaving using bearing driving device.Ram seal is using enhancing flexible graphite structure.It solves
The breakable problem of past soft graphite, guarantees sealing performance under the conditions of high temperature and high pressure condition.
Flashboard uses Integral die-forged structure；Different types of carbide reactor welding technology is used in valve body.Flashboard is using flat
High temperature and high pressure steam both can be recovered the oil or be can be injected to hardened structure, no flow resistance.
The foregoing is merely an embodiment of the present invention, are not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc. within the spirit and principle of utility model, to be included in the utility model
Protection scope within.
