Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
As shown in Figure 1 to 4.A kind of oil field double valve plates lift ball-and-seat, including valve body 1, bonnet 2, valve board assembly
3, the bonnet 2 is arranged on the top of valve body 1, and valve board assembly is arranged on the lower section of bonnet 2, the valve seat of face valve body 1；The valve plate group
Part 3 includes fixed column 5, big mounting disc 6, small sheet-pile 7, positioning tube 8, small valve plate 9, little spring 10, big spring 11, big valve plate 12；
Fixed column 5 is arranged at the lower section of bonnet 2, and its bottom is provided with big mounting disc 6, and the big middle part of mounting disc 6 is provided with small sheet-pile 7, cylindrical
It is provided with 4-6 big spring 11 week, the lower end of big spring 11 connects big valve plate 12, and it is with the level that the big middle part of valve plate 12 is provided with top
Through hole；The middle part of small sheet-pile 7 is provided with little spring 10, and outside is provided with a circle positioning tube 8, and positioning tube 8 is tubular structure, parcel
The firmly root of little spring 10；The bottom of little spring 10 is connected with small valve plate 9, the through hole at the small big center of valve plate 12 of the face of valve plate 9,
And the external diameter of small valve plate 9 is identical with the step internal diameter of the big central through-hole of valve plate 12, the valve seat upper end of the valve body 1 is provided with valve seat
Step 4, the internal diameter of valve seat step 4 is identical with the external diameter of big valve plate 12, and the big lower surface of valve plate 12 is provided with round boss, boss
Outside is provided with a circle seal washer 14, and the external diameter of seal washer 14 is identical with the internal diameter of valve seat step 4, and the big inside of valve plate 12 is provided with
Multiple bayonet locks 13, axle center of the bayonet lock 13 along the big through hole step of valve plate 12 is in axial array, and the small valve plate 9 is surrounded by small
Hole, the position of aperture are corresponding with bayonet lock 13.The end of bayonet lock 13 is provided with spring and steel wire, when needing to block small valve plate 9,
Steel wire loosens, and spring recovers shape and releases bayonet lock 13, protrudes into aperture and is fixed, and when needing to release fixed, pulls back
Steel wire, the micromachine being arranged in big valve plate 12 that loosens and be pulled through of steel wire are completed, micromachine and its and steel
Silk, the structure and annexation of bayonet lock 13, common chuck structure is identical on the market at present.
The little spring 10, its anti-pressure ability are less than big spring 11, and fluid can keep pushing open when pressure is enough
Big spring 11 and little spring 10, it when pressure oscillation diminishes, can ensure that little spring 10 is open, be unlikely to stop completely.
The type of little spring 10 and big spring 11 and the elastic force provided, can be selected, to adapt it to different service conditions as needed
Demand.It is greatly to be threadedly coupled between mounting disc 6 and fixed column 5, in that context it may be convenient to dismantle.
Application method of the present utility model is as follows：
When fluid media (medium) is the larger fluid of the viscosity such as oil, the bayonet lock 13 of valve plate is not-connected status, now, if
Pressure is larger and continual and steady, can push big valve plate 12 and small valve plate 9 open upwards, and small valve plate 9 is pushed up on positioning tube 8, simultaneously
Big valve plate 12 is withstood by small valve plate 9, whole runner is opened completely, facilitate fluid it is continual and steady to the port of export stream of valve body 1
It is dynamic.
When Fluid pressure produces fluctuation, when the elasticity of big spring 11 is more than fluid to the thrust of big valve plate 12, big valve plate 12
It is downwardly against on valve seat step 4, now, if the pressure of fluid is less than little spring 10, little spring 10 also drives small valve plate 9 to press
On the step of the big through hole of valve plate 12, integral sealing is realized, prevents liquid from flowing back,
When the pressure of fluid is more than little spring 10 less than big spring 11, now small valve plate 9 still remains on,
Fluid still can be from the runner between small valve plate 9 and greatly valve plate 12 to Outlet-side flow.
When fluid media (medium) be clear water etc. almost without viscosity liquid when but after little spring 10 is washed open, because fluid can be fast
Speed outflow, without squeezing the big valve body 1 of the support of big spring 11, can also realize that runner is unimpeded.But if for protection little spring
10, its purpose individually done work is reduced, positioning tube 8 is set, can avoid being overly compressed and producing destruction.
, can be with when fluid can provide sufficiently stable pressure, and when needing the big runner to prevent that liquid from excessively washing away small valve plate 9
Bayonet lock 13 is discharged, it is connected big valve plate 12 and small valve plate 9, so as to which the valve plate as an entirety uses.
It ball-and-seat provided by the utility model, disclosure satisfy that the runner in the case of different pressures is unimpeded, while also can
As the ball-and-seat of traditional mode, and it is simple in construction, it is easy to overhaul maintenance.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
