Abstract
The utility model relates to the technical field of oil production, in particular to a multipurpose three-inlet spiral-flow type flow control device. The lower end of an upper valve port cover of the multipurpose three-inlet spiral-flow type flow control device is connected with an outer valve cylinder, a liquid outlet is designed in the lower end of the outer valve cylinder, three inlets are evenly distributed in the circumferential direction of the outer wall of the upper end of the outer valve cylinder, a tapered spiral-flow cylinder is arranged in the outer valve cylinder, and is connected to the lower end of the upper valve port cover, a piston connecting rod penetrates through the upper valve port cover to enter the tapered spiral-flow cylinder, power fastening holes are designed in the upper end of the piston connecting rod, the lower end of the piston connecting rod is connected with a pressure balance type valve plug, the bottom end of the pressure balance type valve plug is open, the pressure balance type valve plug and the tapered spiral-flow cylinder are in sliding seal, and an annular-tapered channel is formed between the outer tapered wall of the lower end of the pressure balance type valve plug and the inner tapered wall of the lower end of the outer valve cylinder. According to the multipurpose three-inlet spiral-flow type flow control device, the purposes that pressure drop caused by impact is reduced, investment cost is reduced, the effect of impact caused by liquid on the side wall of a valve body is reduced, and the service life of the multipurpose three-inlet spiral-flow type flow control device is prolonged are achieved.
Description
Technical field:
The utility model relates to a kind of technical field of petroleum extraction, particularly a kind of multipurpose three the spiral flow at inlet formula flow control devices.
Background technique:
Traditional water injection technology is the technological process that adopts " single pump individual well " of centralized configuration " a pump multistation " at present.This technological process can not meet the requirement of every a bite well targetedly, but adopts unified injection amount, and some wells inject too much, and some wells inject very few.For this problem, domestic existing flow control valve has effectively solved this problem, and still existing flow control valve, because the impact of head causes the loss of fluid pressure to increase, makes to inject cost and improves, and reduces the working life of spool.In use liquid is large to the impact of body wall in the design of single entrance simultaneously, causes the valve body life-span to reduce.
Model utility content:
The technical problems to be solved in the utility model is to provide a kind of multipurpose three the spiral flow at inlet formula flow control devices, this device has been realized and has been reduced the pressure drop causing because impacting, reduce and inject cost, reduce the percussion of liquid to body wall, the working life of extension fixture.Overcome existing flow control valve large because impacting the pressure drop causing, injected cost high, liquid is large to the percussion of body wall, reduces the deficiency in the working life of device.
Technical solution adopted in the utility model is: a kind of multipurpose three the spiral flow at inlet formula flow control devices, comprise piston brace rod, upper Valve mouth cover, outer valve cylinder and liquid outlet, upper Valve mouth cover lower end connects outer valve cylinder, outer valve cylinder lower end design liquid outlet, outer valve cylinder upper end outer wall week is upwards evenly equipped with three entrances, eddy flow conically shaped is placed in outer valve cylinder and is connected to Valve mouth cover lower end, piston brace rod enters eddy flow conically shaped through upper Valve mouth cover, piston brace rod upper end is designed with power and tightens up hole, piston brace rod lower end Bonding pressure balanced type spool, pressure balance type spool bottom end opening, slipper seal between pressure balance type spool and eddy flow conically shaped, between the conical inboard wall of the conical outer wall of pressure balance type spool lower end and outer valve cylinder lower end, form ring tapered channel.
The beneficial effects of the utility model are: the utility model has reduced the pressure drop causing because impacting, and has reduced injection cost, has reduced the percussion of liquid to body wall, have extended the working life of device.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1, a kind of multipurpose three the spiral flow at inlet formula flow control devices, comprise piston brace rod 1, upper Valve mouth cover 2, outer valve cylinder 4 and liquid outlet 6, upper Valve mouth cover 2 lower ends connect outer valve cylinder 4, outer valve cylinder 4 lower end design liquid outlets 6, outer 4 upper end outer wall weeks of valve cylinder are upwards evenly equipped with three entrances 3, eddy flow conically shaped 8 is placed in outer valve cylinder 4 and is connected to Valve mouth cover 2 lower ends, piston brace rod 1 enters eddy flow conically shaped 8 through upper Valve mouth cover 2, piston brace rod 1 upper end is designed with power and tightens up hole 7, piston brace rod 1 lower end Bonding pressure balanced type spool 5, pressure balance type spool 5 bottom end openings, slipper seal between pressure balance type spool 5 and eddy flow conically shaped 8, between the conical inboard wall of the conical outer wall of pressure balance type spool 5 lower ends and outer valve cylinder 4 lower ends, form ring tapered channel.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
