Description
Technical field
The utility model belongs to oil drilling technical field, and in particular to a kind of sand control lock of two way seal.
Background technology
In oil and gas wellhead device, sand control Flat Sluice is that one kind is commonly used in drilling well manifold, the device on fracture manifold, mainly
Conflux logical for oil field pressure break, well casing and close, its closing principle is：Two way seal (descends greasing hole to tear open in off position
Except pressure testing ne-leakage) rotated by a valve rod, another is relative between the up and down motion conversion gate valve of valve rod and valve seat
The open and close of valve are realized in position.Flashboard profile is cuboid, and cuboid is provided with the twice metallic sealing section being parallel to each other,
Upper end is provided with the T-slot of connection valve rod, and lower end is provided with the circular hole perpendicular to two sealing surfaces, and valve rod and valve plate Position Design have down
Angle.It is the standard-sized sheet of valve when the through hole on the descending closed valve seat of the entity part on flashboard top overlaps.Such structure is in work
Make to be practicable in principle, but there is following drawback in actual use：Because the closure of gate valve is by the descending of flashboard
Come what is realized, therefore, valve body inner bottom part must leave the space for making flashboard descending, and actually this space but becomes mud and leads to
The deposition ground crossed in gate valve, when gate valve interruption is not used, this part mud will be dried and is hardened, and directly influence valve plate just
It is often descending, valve is not had the effect of normal switching-off unlatching.
Utility model content
The purpose of this utility model is to provide a kind of two way seal valve lock, with solve mud into valve body to cause sealing
Lock cannot normal work problem.
The utility model provides following technical scheme：A kind of two way seal gate valve, includes valve body, valve rod, bonnet
And flashboard, the valve rod is connected with flashboard, and the bonnet is bolted to connection with valve body, and receiving is provided with the valve body
The valve pocket of flashboard, valve body is provided with the fluid passage vertical with valve pocket and is connected with valve pocket；On the flashboard apart from flashboard bottom 10 to
20 centimeters are provided with the through hole with the fluid passage equal diameters on valve body；The valve body fluid passage be provided with outer seat and
Inner seat, the outer seat and inner seat are in valve pocket inside and are close to the both sides of flashboard, are formed between valve body and flashboard
Sealing surface.
Preferably, the valve pocket cross section in the valve body for circle, and valve pocket cross section diameter be slightly less than valve plate and
The diameter of the cross section sum of inside and outside valve seat.
Preferably, the outer seat is respectively equipped with sealing ring with inner seat, and the material of the sealing ring is polytetrafluoroethylene (PTFE).
Preferably, the flashboard is stainless steel, extends the service life of flashboard.
Preferably, the two way seal lock also treasure-house handwheel, handle is provided with the marginal position of handwheel.
The beneficial effects of the utility model are：The utility model provides a kind of two way seal lock, when rotary handle makes valve
When being shown in a fully open operation, the through hole that mud enters on flashboard from the fluid channel inlet of valve is again from the outlet stream of fluid passage
Go out, now interior outer seat can launch simultaneously, and realize sealing by pressure, therefore mud will not enter into the descending sky of flashboard
Between in, will not more produce accumulation of mud phenomenon and cause sealing lock cannot normal work.
Brief description of the drawings
Accompanying drawing is used for providing being further understood to of the present utility model, and constitutes a part for specification, with this practicality
New embodiment is used to explain the utility model together, does not constitute to limitation of the present utility model.In the accompanying drawings：
Fig. 1 is the structural representation of the utility model two way seal lock；
Fig. 2 is to seal the schematic diagram that outer seat launches simultaneously in both sides under lock open mode；
Fig. 3 is the schematic diagram of unilateral inside and outside valve seat expansion under sealing lock closed mode.
Specific embodiment
As Figure 1-3, a kind of two way seal gate valve, includes valve body 1, valve rod 5, bonnet 6 and flashboard 4, valve rod 5 and lock
Plate 4 is fixedly connected, and bonnet 6 is bolted to connection with valve body 1, and the valve pocket 11 for accommodating flashboard 4, valve body 1 are provided with valve body 1
It is provided with the fluid passage 12 vertical with valve pocket 11 and fluid passage connects with valve pocket 11；On flashboard 4 apart from the bottom 10 of flashboard 4 to
The position of 20 centimeters, is provided with the through hole 41 with the equal diameters of fluid passage 12 on valve body, and flashboard 4 can be cuboid,
Can also be cylinder；The fluid passage 12 of valve body 1 is provided with outer seat 2 and inner seat 3, and outer seat 3 and inner seat 3 are in valve pocket
11 inside are simultaneously close to the both sides of flashboard 4, form the sealing surface between valve body 1 and flashboard 4.The cross section of valve pocket 11 in valve body 1
It is circle, valve pocket 11 is cylindrical cavity, uniform force, and the diameter of the cross section of valve pocket 11 is slightly less than flashboard 4 and inside and outside valve seat 3,2
Cross section sum diameter, i.e., the ultimate range between the neighboring of outer seat 3 slightly larger than valve pocket 11 diameter.
In the present embodiment, outer seat 3 is respectively equipped with sealing ring 9 with inner seat 2, it is ensured that sealing property, the sealing ring 9
Material elects polytetrafluoroethylene (PTFE) as.Flashboard 4 is stainless steel, so extends the service life of flashboard.The two way seal lock also includes hand
Wheel 7, handwheel 7 is threaded on bonnet 6, and handle 8 is provided with the edge optional position of handwheel 7, and the diameter of handwheel 7 is enough big.
