Abstract
The utility model relates to a water injection control valve for a water injection well. The water injection control valve comprises a valve body, wherein the valve body comprises a valve body inlet, a valve body outlet, a valve core and a valve seat, a valve rod is arranged in the valve body, the valve core is in pin joint with the valve rod through a pin, the valve core is a conical valve core, a taper sleeve is arranged above the valve seat, and the taper sleeve is closely matched with the conical valve core. Compared with the prior art, the water injection control valve disclosed by the utility model has the characteristics of simple structure, durability, low manufacture cost and wear resistance, and is suitable for application and popularization.
Description
Technical field
The utility model relates to the valve body technical field, and is particularly a kind of wear-resistant, the water injection well water filling control valve of long service life.
Background technology
In the oil exploitation process, along with the continuous extraction of underground crude oil, stratum energy descends, and liquid level constantly reduces in the oil well, and the well yield of producing well descends obviously, has increased the cost that recovers the oil.In order to slow down the decline of stratum energy, present domestic oil field takes to bore water injection well at the producing well periphery mostly, injects liquid through water injection well to the stratum, improves stratum energy.Because the various places condition is different, and the oil field is in remote districts mostly, and the water treatment condition does not reach the requirement of injection water quality, and this just brings corrosion in various degree to flood pattern, and what wherein have the greatest impact is exactly water injection well water filling control valve.If water quality impurity content exceeding index in the water filling will heavy wear water filling control valve.In the water filling control valve is worn quite serious the time, often causes, leak phenomenon, can't effectively control the water filling injection allocation amount of water injection well, do not reach the purpose of effective water filling.The common water filling control valve that adopts at present often uses just necessary integral replacing of one or two months, otherwise the serious consequence of leaking in can causing, and the water filling control valve that entire body uses antifriction metal (AFM) to process because cost is too high, can not be used widely.For this reason, be badly in need of low, the wear-resisting water filling control valve of a kind of cost on the market.
Therefore, design a kind of wear-resistant, long service life, the water injection well water filling control valve of low cost of manufacture is the technical problem that those skilled in the art need solution badly.
The utility model content
The purpose of the utility model provides a kind of water injection well water filling control valve of simple in structure, easy to use, low cost of manufacture.
The technical scheme of the utility model is:
A kind of water injection well water filling control valve; Comprise valve body, said valve body comprises valve body import, valve outlet, spool and valve seat, it is characterized in that: valve inner is provided with valve rod; Spool is through pin and valve rod pin joint; Said spool is a taper valve core, and said valve seat top is provided with tapered sleeve, and said tapered sleeve and taper valve core closely cooperate.
As optimal technical scheme, the said tapered sleeve of the utility model adopts abrasion-resistant stee or wear resistant cast iron to make.
As optimal technical scheme, the said valve seat of the utility model adopts antifriction metal (AFM) or abrasive rubber to make.
As optimal technical scheme, the said valve body inner spool of the utility model and the inwall of valve seat contact jaw are provided with wear-resistant device.
As optimal technical scheme, the said wear-resistant device of the utility model is processed for the employing abrasive rubber that is fixedly connected with valve interior wall and outer surface has the liner lasso of decorative pattern.
The beneficial effect of the utility model is:
The inwall of the utility model valve body inner spool and valve seat contact jaw is provided with wear-resistant device, has improved its tear strength;
Adopt taper valve core, further, said valve seat top is provided with tapered sleeve, and said tapered sleeve and taper valve core closely cooperate, and like this, spool are pressed on the valve seat tightly, and making between spool and the valve seat does not have the gap.
In addition, said tapered sleeve adopts wear-resisting material to make, as with abrasion-resistant stee or wear resistant cast iron etc.The further like this abrasion resistance of strengthening the utility model prolongs its application life.
Description of drawings
Fig. 1 is the structural representation of the utility model;
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 is the structural representation of the utility model embodiment 1.As shown in Figure 1, a kind of water injection well water filling control valve comprises valve body 1; Said valve body 1 comprises valve body import 2, valve outlet 3, spool 4 and valve seat 5; Valve body 1 inside is provided with valve rod 6, and spool 4 is through pin and valve rod 6 pin joints, and said spool 4 is a taper valve core; Said valve seat 5 tops are provided with tapered sleeve 7, and said tapered sleeve 7 closely cooperates with taper valve core.Said tapered sleeve 7 adopts abrasion-resistant stee or wear resistant cast iron to make.Said valve seat 5 adopts antifriction metal (AFM) or abrasive rubber to make.
In order to improve the abrasion resistance of valve body 1, prolong its application life, said valve body 1 inner spool 4 is provided with wear-resistant device with the inwall of valve seat 5 contact jaws.Further, said wear-resistant device is processed for the employing abrasive rubber that is fixedly connected with valve body 1 inwall and outer surface has the liner lasso 8 of decorative pattern.
During water filling, regulation valve body 1 makes valve rod 6 drive spools 4 and moves up, and makes between spool 4 and the valve seat 5 and forms the gap in water injection well, and current get into from valve body import 2, from valve outlet 3 outflows; After water filling finishes, through the valve body 1 of screwing, spool 4 and valve seat 5 are closely cooperated, stop current.
The above is merely the preferred embodiment of the utility model; Be not therefore and the claim of restriction the utility model; Every equivalent structure transformation that utilizes the utility model manual and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
