Abstract
The invention belongs to a fixing valve, comprising a strip-shaped nut, a fixing valve shield and a U-shaped combined joint; a first round hole is formed in the top of the fixing valve shield; a second round hole is formed in the bottom of the fixing valve shield; the strip-shaped nut is arranged in the second round hole; the U-shaped joint is arranged in the first round hole; a scale settling device is arranged below the strip-shaped nut. The mode of jointing the U-shaped combined joint and the scale settling device is adopted by the fixing valve, the sundry, sand and scales are blocked in the annular space formed by the U-shaped combined joint and the fixing valve shield, sands and scales are prevented from being accumulated in the inner cavity of the scale settling device, and the fixing valve is prevented from being blocked, so the use period is prolonged and the production efficiency o f an oil field is improved.
Description
Technical field
The present invention relates to a kind of standing valve.
Background technology
Standing valve in traditional oil production technology, owing to being subject to pumping pipe string inwall foreign material fall well and formation sand production, the factor impacts such as fouling, the sand, dirt and the pipe string internal wall foreign material that are entrained in liquid stream are easy to deposit at standing valve cover place, have a strong impact on the normal opening and closing of standing valve, thereby cause standing valve to be blocked.
Summary of the invention
The technical problem to be solved in the present invention is just to provide and a kind ofly prevents that sand, dirt deposition are in the standing valve at standing valve cover place.
For addressing the above problem, the present invention adopts following technical scheme: a kind of standing valve, comprise bar shaped nut, standing valve cover and U-shaped built-up joint, described standing valve cover top is provided with the first circular hole, described standing valve cover bottom is provided with the second circular hole, described bar shaped nut is arranged in the second circular hole, and described U-shaped built-up joint is arranged in the first circular hole, and the below of described bar shaped nut is provided with heavy dirty device.
As preferably, described U-shaped built-up joint is divided into three parts compositions, is made up of two L-type bonding jumpers and a short bonding jumper.
As preferably, in described standing valve cover, be provided with a v-notch.
As preferably, on described heavy dirty device, be provided with screw thread.
The invention has the beneficial effects as follows: the form that this standing valve adopts U-shaped built-up joint to dock with heavy dirty device, foreign material, sand, dirt are got lodged in U-shaped built-up joint and standing valve cover annular space, avoid heavy dirty device inner chamber sand setting, incrustation, prevent that standing valve from being blocked, thereby extend life cycle, improved production efficiency of oilfields.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of standing valve of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
Consult shown in Fig. 1, a kind of standing valve, comprise bar shaped nut 1, standing valve cover 2 and U-shaped built-up joint 3, described standing valve cover 2 tops are provided with the first circular hole 4, described standing valve cover 2 bottoms are provided with the second circular hole 5, described bar shaped nut 1 is arranged in the second circular hole 5, and described U-shaped built-up joint 3 is arranged in the first circular hole 4, and the below of described bar shaped nut 1 is provided with heavy dirty device 6.
Described U-shaped built-up joint 3 is divided into three part compositions, is made up of two L-type bonding jumpers and a short bonding jumper.In described standing valve cover 2, be provided with a v-notch 7.On described heavy dirty device 6, be provided with screw thread (not shown).
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
