Description
Technical field：
It is especially a kind of high to heavy crude heat extraction and high temperature the present invention relates to the engineerings device such as electric heating and oil field gas injection exploitation
The special valve that pressure steam is controlled.
Background technology：
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 flap type
Exactly specially manufacture and design for this operating mode situation of heavy crude heat extraction and the defeated vapour oil recovery pipeline of high temperature and pressure.
The deficiency of traditional product：It is 70.0MPa, flow resistance that the steam pipework of traditional viscous crude, which uses shut-off valve, general pressure,
Greatly, operating force is away from big, inconvenient for operation, inefficiency.Entire pipeline is very long, extremely inconvenient, while equipment cost becomes larger.Flashboard
Due to not can solve the compensation that sealing ring is resistance to high and is used for a long time after abrasion.Service life is extremely short, just less than 10 months
Influence and a large amount of manpower of needs stopped work when needing replacing new valve, cause greatly to waste, and replacing to production.It is right
It cannot be sealed in the well head more than 105.0MPar, newly-designed super-pressure well head flat gate valve resistance to can arrive 150.0MPa.
Invention content：
Purpose of the present invention is to propose a kind of superhigh-pressure high-temp well head flap type, can be sealed when well head conveys, newly set
The super-pressure well head flat gate valve of meter resistance to can arrive 150.0MPa.
The technical scheme is that superhigh-pressure high-temp well head flap type, including valve body, butterfly spring, valve seat, enhancing are soft
Property carbon seal ring, flashboard, valve deck, combination sealing filler, metallic packing ring, valve rod；Valve body center valve seat is equipped with communicating valve
The lower part in the hole of door inlet and outlet, the through-hole of cut-out cock when flashboard covers downwards valve seat, the hole imported and exported on valve seat is equipped with flashboard
The gap extended downwardly into, valve seat are equipped with a pair of of butterfly spring, and the butterfly spring is the butterfly spring of central openings, in described
Entreat the hole that trepanning is imported and exported with valve on an axis, the gap between a pair of of butterfly spring is matched with flashboard, and flashboard is downward
It is fitted close with the first plane of butterfly spring when cut-out cock when covering valve seat, the second plane fitting enhancing of butterfly spring is soft
Property carbon seal ring be fixed on valve seat, enhancing flexible graphite sealing ring be and the circle shape of butterfly spring same shape seal
Circle, flashboard top connect valve rod, fix valve deck above valve seat, metallic packing ring is equipped between valve seat and valve deck；Valve rod is in valve deck
Inside, valve rod are equipped with combination sealing filler and filler gasket, and the gap that flashboard extends downwardly into is by the tail end and flashboard of flashboard
The valve rod in portion supports valve plate together, can be resistant to the oil and the possible pressure of power industry of 150M.
The bearing of socket valve rod is equipped with above the combination sealing filler and Packing seat piece of valve rod so that the movement of valve rod is more
Flexibly, handwheel and the screw thread of valve rod outer rim match, and valve is unlatched and closed so as to relatively labor-saving.
As shown, when valve rod moves upwards, valve rod drives flashboard to be lifted up, and opens entire channel, injects
The steam of high temperature and pressure and oil recovery.When valve rod moves downward, and reaches rest position, entire channel is closed, terminates high temperature
The steam of high pressure is injected and is recovered the oil.
Advantageous effect：Flashboard uses slab construction, no flow resistance that can carry out recovering the oil or injecting high temperature and pressure steaming
Vapour.Valve switch and laborsaving is facilitated using bearing driving device.Flashboard is using tablet butterfly spring and ram seal using resistance to super
High pressure novel enhanced soft graphite special construction has good sealing effect, using straight through flow channel type structure, no flow resistance.It adopts
With bearing driving device.Filler uses resistance to super-pressure composite structure；Valve body and valve deck use Integral die-forged structure, and valve seat is not using
Prepared by congener carbide reactor welding technology, keep sealing surface corrosion-resistant, impact resistance ensures the service life of valve.Flashboard is adopted
With slab construction, no flow resistance can carry out recovering the oil or injecting superhigh-pressure high-temp steam.
Valve switch and laborsaving is facilitated using bearing driving device.Ram seal uses resistance to super-pressure novel enhanced flexibility stone
Black special construction, the breakable problem of the soft graphite of solving over, ensures the leakproofness under superhigh-pressure high-temp working condition
Energy.Filler uses resistance to super-pressure composite structure, ensures the reliability of sealing.
