Description

The hard metallic seal slurry valve of high-pressure well mouth
Technical field:
The utility model relates to a kind of valves, are especially adapted for use in the engineerings such as oilfield exploitation, control oilfield exploitation Special valve.
Background technique:
With the high speed development of the national economy in China.The growth of the crude oil needed at double, the valve for control piper It is more and more, while sulfide etc. of increasingly more oil fields by development & construction, since oil density is big and hardened, in crude oil Corrosive substance content is high.Key effect is just played in the valve of well head.This operating condition situation of high pressure oil recovery pipeline is specially set Meter manufacture.
Deficiency existing for traditional product: traditional mud valve, flow resistance is big, and operating force is away from big, inconvenient for operation, low efficiency Under.Equipment cost becomes larger simultaneously.Flashboard is due to the compensation after not can solve the resistance to high abrasion with long-time service of sealing ring.Make It is extremely short with the service life, new valve was just needed replacing less than 10 months, causes greatly to waste, and was stopped work when replacement to production Influence and need a large amount of manpower.
Utility model content:
The purpose of this utility model is to propose a kind of hard metallic seal slurry valve of high-pressure well mouth, is guaranteed under high pressure working condition Sealing performance.Guarantee reliable sealing at elevated pressures.Keep sealing surface resistance to using different types of carbide reactor welding technology Corrosion, impact resistance guarantee the service life of valve.
The technical solution of the utility model is a kind of hard metallic seal slurry valve of high-pressure well mouth, including valve body, flashboard, valve seat, gold Belong to sealing ring, valve deck, valve rod, composite filling, Packing seat, gland, bracket, lubricating cup, bearing, valve stem nut, handle;By with The fixed valve rod of flashboard and handle control flashboard, that is, spool move up and down in valve seat, and the upper and lower movement position of flashboard corresponds to valve Conducting and cut-off;Valve seat is a pair of parallel alloy annulus insertion valve body, and annulus center is the runner of valve, and the upper end of valve body is valve Lid, valve deck is interior to be equipped with composite filling, Packing seat, gland, bracket, lubricating cup, bearing, valve stem nut, handle;Valve rod is by combining Filler, Packing seat are wrapped up in gland and are connect with the bracket on composite filling top, handle;Valve stem nut, flashboard, valve rod, Lubricating cup, bearing;Bonnet lower is equipped with metallic packing ring, and valve body is isolated with valve deck, and metallic packing ring tight fit wraps up valve rod.It fills out Material uses composite structure.
It is moved up and down by valve rod and handle the control flashboard i.e. spool fixed with flashboard in valve body fluid passage, flashboard Upper and lower movement position corresponds to the conducting and cut-off of valve;Valve deck inner valve stem top, that is, metallic packing ring top is equipped with combination and fills out Material, composite filling top are equipped with bracket, lubricating cup, bearing, valve stem nut;
Flashboard uses heap hard alloy flat plate sealing structure.As shown, using straight through flow channel type structure, no flow resistance.
Using metal sealing ring structure;Valve body uses Integral die-forged structure;Using different types of hard alloy overlay welding skill Art.
The course of work: as shown, when valve rod moves upwards, valve rod drives flashboard to be lifted up, and opens entire Channel guarantees passing through for the impurity such as mud.When valve rod moves downward, and reaches rest position, entire channel is closed, is terminated The exploitation of the impurity such as mud.
The utility model has the advantages that flashboard uses slab construction, no flow resistance.Ram seal uses pile-up welding hard alloy special construction, protects Demonstrate,prove the sealing performance under high pressure working condition.Using metal sealing ring structure, guarantee reliable sealing at elevated pressures.Filler Using composite structure, guarantee the reliability of sealing.Keep sealing surface corrosion-resistant using different types of carbide reactor welding technology, it is resistance to Impact, guarantees the service life of valve.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown, 1, valve body, 2, sealing ring, 3, flashboard, 4, sealing ring, 5, valve seat, 6, sealing ring, 7, metal sealing Ring, 8, valve deck, 9, valve rod, 10, stud, 11, hex nut, 12, composite filling, 13, Packing seat, 14, mark closely screw, 15, gland, 16, bracket, 17, lubricating cup, 18, bearing, 19, valve stem nut, 20, sealing ring, 21, handle.
Point-blank, flashboard with flashboard by fixing for high-pressure well mouth hard metallic seal slurry valve, valve body upper outlet and outlet Valve rod and handle control flashboard, that is, spool move up and down in valve seat, and the upper and lower movement position of flashboard corresponds to the outlet of valve and goes out Conducting and cut-off between mouthful;Valve seat is a pair of parallel alloy annulus, is embedded in valve body, annulus center is the outlet and outlet stream of valve Road, flashboard, which is inserted into parallel alloy annulus, can guarantee good sealing structure;The upper end of valve body is valve deck, is equipped with combination in valve deck Filler, Packing seat, gland, bracket, lubricating cup, bearing, valve stem nut, handle;Valve rod is by composite filling, Packing seat, filler It wraps up in gland and is connect with the bracket on composite filling top, handle;Valve stem nut, flashboard, valve rod, lubricating cup, bearing;Under valve deck Portion is equipped with metallic packing ring, and valve body is isolated with valve deck, and metallic packing ring tight fit wraps up valve rod.Filler is all made of combination knot Structure.
It is moved up and down by valve rod and handle the control flashboard i.e. spool fixed with flashboard in valve body fluid passage, flashboard Upper and lower movement position corresponds to the conducting and cut-off of valve;A pair of parallel alloy annulus rub resistance and machining accuracy height, are embedded in valve Body can become the structure sealed firmly, and annulus center is the outlet and outlet flow of valve.
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.
