Description
Technical field
The utility model is related to oil and gas wellhead valve, and in particular to a kind of Dual sealed valve.
Background technology
Existing oil and gas wellhead valve, is sealed between valve body and bonnet using gasket ring, and " O " is used between valve body and valve seat
Type groove rubber seal rings for seal, is influenceed by corrosive gas, gravel etc. in working environment so that sealing position abrasion, corrosion, drop
The integral sealing effect of low valve is, it is necessary to which irregular replacing seal member, increases production cost, and the maintenance for shortening valve is all
Phase, the overall oil recovery efficiency of reduction.
The content of the invention
The purpose of this utility model is：A kind of Dual sealed valve is provided, between valve seat and valve body, valve body and bonnet
Respectively one of water wave linear sealing of increase, is not only greatly enhanced sealing property, moreover it is possible to be effectively protected valve seat rubber ring and gasket ring is close
Envelope position is not influenceed by corrosive gas, gravel etc., improves valve overall sealing performance, extension valve maintenance cycle and the longevity of use
Life.
Technical solution of the present utility model is：The valve include valve rod, bonnet, bolt and nut, locking cap, valve plate,
Valve seat insert, steel ring gasket ring, valve seat and valve body, bonnet are connected with valve body by bolt and nut, and steel ring gasket ring is positioned over valve body
Placed between bonnet, in the valve seat orifice of body cavity and valve seat insert is placed on valve seat, valve seat, valve plate passes through locking with valve rod
Cap is connected, and valve rod is emerged bonnet, it is characterized in that：A water wave sealing surface together is designed on contact surface between valve body and bonnet,
Another No. two water wave sealing surfaces in road are designed on contact surface between valve seat and the valve seat orifice of valve body；A number water wave sealing surface and No. two
Water wave sealing surface structure is identical, is made up of several in the water wave line of concentric circles, and water wave sealing surface occlusion elastic diaphragm
Pad；Under the tightening of bolt and nut, extruded by the valve body and bonnet that arrive so that steel ring gasket ring and a water wave sealing surface
Deformation produces sealing；Valve seat is under the extruding by valve rod so that valve seat insert and No. two water wave sealing surface crimp shapes
Into sealing.
Wherein, spacing is 0.4mm or 0.8mm between two water wave lines.
The utility model has the advantages that：
1st, valve body profile uses square structure, and connecting portion abandons traditional flange connection, is directly connected using bolt
Connect, so that valve body is easy to process, weight is lighter, and volume is smaller.
The 2nd, bonnet is installed on valve body, is tightened by bolt and nut, steel ring gasket ring and water wave between extruding valve body, bonnet
Sealing surface, not only causes the deformation of steel ring gasket ring and seal groove between valve body, bonnet to seal, and also causes valve body, the water on bonnet
The elastic diaphragm pad of line sealing surface occlusion therebetween, produces Light deformation after the occlusion of water wave sealing surface, forces under the effect of the pressure
A rule metallic closed ring is formed at occlusion, each circle becket is all small one sealing, not only plays sealing function, moreover it is possible to
Effectively protect steel ring gasket ring position, it is to avoid influenceed by gravel in external environment condition etc..
3rd, valve seat, valve seat connection valve plate, valve plate extruding valve seat so that valve seat is to valve are installed in the valve seat hole site of body cavity
Body valve seat orifice is extruded, and forces water wave sealing surface to be engaged elastic diaphragm pad, water wave sealing surface is due to also by valve plate after occlusion
Squeezing action so that water wave seals facial disfigurement, is fully sealed closure, the becket that a rule is closed is formed, not only in valve seat
Hole portion position formation double-pole sealing, moreover it is possible to effectively protect valve seat insert position not influenceed by corrosive gas, gravel etc. in operating mode,
Extend the Sealing period of valve seat insert, improve the maintenance period of a whole set of valve.
4th, simple in construction, easy to process, production cost is low, and sealing effectiveness more preferably, extends maintenance period, and raising uses the longevity
Life.
5th, two road water wave sealing surfaces are added again on the basis of original sealing, not only forms dual close with original sealing position
Seal effect, moreover it is possible to which play the original seal member of protection is not influenceed by operating mode fluid, gas and particle, is further lifted original close
The sealing effectiveness at position is sealed, the maintenance period of a whole set of valve is extended, improves the service life of valve.
6th, valve body is directly connected by screw bolts bonnet, it is to avoid the weight of flange connection, the volume for reducing a whole set of valve is empty
Between, this has greatly for those wellhead platforms affected by environment required to volumetric spaces, load-bearing, particularly ocean platform
Ground is acted on, and enables to platform to install more wellhead equipments under effective space, limited carrying, and raising uses efficiency.
