Abstract
The utility model relates to a high-pressure adjustable waterflooding valve for oil field layering, which comprises a casing, a water inlet and a water outlet. The utility model is characterized in that a valve seat is arranged in the casing, two water passing holes are arranged on the valve seat, and through holes are arranged at the middle of the valve seat; a regulating rod is arranged in the holes, the lower part of the adjusting rod is connected with a hole on a movable valve, and two water passing holes are arranged on the movable valve; the regulating rod which is extended out of the lower end of the movable valve is provided with a pressing spring, the two water passing holes on the valve seat and the two water passing holes on the movable valve are waist-shaped holes, and the position of the two water passing holes on the valve seat and the position of the two water passing holes on the movable valve are corresponding to each other. The utility model has the advantages that the flow quantity of the high-pressure waterflooding valve can be conveniently controlled at the deep of the oil well, and the requirement of the high-pressure waterflooding of the oil field layering can be satisfied.
Description
Technical field
The utility model relates to a kind of water injection valve, the adjustable water injection valve of particularly a kind of oil field layering high pressure.
Background technology
When in the layering high pressure water injection of oil field, needing to regulate the underground water-injection flow at present, the high pressure water injection valve can only be proposed from the down-hole, change the water nozzle of suitable bore then, because it is dark that the high pressure water injection valve is positioned at down-hole hundreds of rice, therefore regulate the underground water-injection flow with the mode of changing the high pressure water injection valve and can increase labour intensity greatly, and it is very loaded down with trivial details to change operation.
Summary of the invention
The purpose of this utility model is to solve when needing to regulate the underground water-injection flow in the layering high pressure water injection of oil field in the prior art, the high pressure water injection valve can only be proposed from the down-hole, change the water nozzle of suitable bore then, because it is dark that the high pressure water injection valve is positioned at down-hole hundreds of rice, therefore regulate the underground water-injection flow with the mode of changing the high pressure water injection valve and can increase labour intensity greatly, change the very loaded down with trivial details problem of operation.The adjustable water injection valve of the utility model design oil field layering high pressure, comprise housing, water inlet, delivery port, it is characterized in that: valve seat is arranged in the housing, two water holes are arranged on the valve seat, there is through hole the centre of valve seat, adjusting rod is arranged in the hole, the bottom of adjusting rod connects the hole on the moving valve, on the moving valve two water holes is arranged, and stretching out on the adjusting rod that moves the valve lower end has holddown spring, two water holes on valve seat and the moving valve are mounting hole, and the position of two water holes on valve seat and the moving valve is corresponding mutually.The utility model has the advantages that and easily the flow of high pressure water injection valve to be controlled in the oil well depths, satisfy the requirement of oil field layering high pressure water injection.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated, accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is a valve seat construction vertical view of the present utility model, and accompanying drawing 3 is a moving valve arrangement vertical view of the present utility model,
Comprise housing 1 among the specific embodiment figure, water inlet 2, delivery port 3, it is characterized in that: valve seat 4 is arranged in the housing 1, two water holes 5 are arranged on the valve seat 4, there is through hole 7 centre of valve seat 4, adjusting rod 6 is arranged in the hole 7, the bottom of adjusting rod 6 connects the hole 9 on the moving valve 8, on the moving valve 8 two water holes 10 are arranged, stretch out on the adjusting rod 6 that moves valve 8 lower ends holddown spring 11 is arranged, two water holes 5 on valve seat 4 and the moving valve 8,10 is mounting hole, two water holes 5 on valve seat 4 and the moving valve 8,10 position is corresponding mutually, when needs change the discharge of high pressure water injection valve, and rotary regulating lever 6, adjusting rod 6 drives moving valve 8 and rotates, because two water holes 5 on valve seat 4 and the moving valve 8, therefore 10 is mounting hole, when valve seat 4 and moving valve two water holes 5 about in the of 8,10 pairs punctual, the flow maximum, and turn an angle, valve seat 4 and moving valve two water holes 5 about in the of 8,10 partially overlap, and have then reduced flow, and this can regulate the discharge of high pressure water injection valve easily again.
Claims (3)
