Abstract
The utility model relates to an automatically counter-flow resisting device. A shell is a three-way conjoined pipe; a drain plug is a cylinder the diameter of which is matched with the inner diameter of a straight pipe of the shell; the drain plug blocks the pipe end of the shell; one side wall of the inner end of a drain plug pipe is provided with a convex plate having a ring groove; one end of a connecting flower sleeve with holes on the wall is stuck in the groove of the convex plate; the port is blocked by the convex plate; the holes on the wall are aligned with a branch pipe hole; the other end of the connecting flower sleeve is positioned on the other end of the branch pipe hole; the diameter of the inner wall is matched with the diameter of the outer wall of one end of a flower sleeve; the outer wall of the other end of the flower sleeve is connected with the inner wall of a valve seat sleeve; the diameter of the outer wall of the valve seat sleeve is matched with the inner diameter of the straight pipe and the valve seat sleeve is arranged on the water inlet end of the straight pipe; the outer wall and the inner wall of the straight pipe are sealed by a seal ring; the valve seat is a circular ring, is embedded on the valve seat sleeve and is provided with a spherical valve core seat which is positioned in a space formed by the connecting flower sleeve, the flower sleeve, the valve seat and the valve seat sleeve. The automatically burst-resisting device can prevent counter flow of the working medium and is suitable for preventing working medium such as liquid, gas and the like from counter flow.
Description
Technical field
The utility model relates to the automatic counnter attack of unidirectional transportation work medium in the injecting process of a kind of water injection well in oil fields and tells device.
Background technology
In the oil-field flooding process, during because of a variety of causes termination of pumping, it is moving to the low well stream of strata pressure by the high well of strata pressure to inject water, causes that the stratum is counter tells or shake out.When normal water filling,, malfunctioning in the time of need closing because pressure oscillation causes the sealing unit of common (spring ball formula, trap formula) ball-and-seat to damage greatly because of vibrations.
The utility model content
The purpose of this utility model provides a kind of when the working media forward flow, spool is moving on by jack-up under the pressure medium effect, realize opening, when the working media reverse flow, spool falls under the effect of pressure medium and spool gravity, realization is closed, and makes the automatic counnter attack that working media can not reverse flow tell device.
It is to be made of housing, plug, connection flower cover, flower cover, spool, valve seat, valve seat cover that device is told in the automatic counnter attack of water injection well described in the utility model; Housing is one to constitute the disjunctor pipe of threeway by arm and straight tube, one end of straight tube has internal thread, plug be a diameter and housing straight tube internal diameter be complementary above have externally threaded cylinder, plug precession pipe end blocks the housing pipe end, plug outer wall and inner walls are sealed by sealing ring, there is the diameter that has a circle groove on the sidewall plug pipe the inner less than the boss of plug diameter, connection flower cover one end that has the hole on the wall is stuck in the boss groove, port is blocked by boss, tap is aimed in the hole that has on the wall, the other end that connects the flower cover is positioned at the other end of tap, outer diameter and straight tube internal diameter are complementary, inner diameter is complementary with flower cover one end outer diameter, flower cover other end outer wall is connected with valve seat cover inwall, valve seat cover outer diameter and straight tube internal diameter are complementary, be positioned at the water inlet end of straight tube, outer wall and straight tube inwall are sealed by sealing ring, valve seat is an annulus, being embedded in valve seat puts, spherical valve core is sitting on the valve seat, is positioned at by connecting the flower cover, the flower cover, valve seat, in the space that the valve seat cover forms.
When the working media forward flow, spool is moving on by jack-up under the pressure medium effect, realizes opening, and when the working media reverse flow, spool falls under the effect of pressure medium and spool gravity, realizes closing, and makes the working media can not reverse flow.Thereby realize the way flow function.
The described automatic counnter attack of present embodiment is told device and is had following having a few:
1, the pressure loss is little: the entrance and exit area of passage is identical, does not produce throttling, and the pressure loss of convection cell is little.
2, sand control, abrasion resistance can be good: key positions such as spool adopt super wear-resisting, high strength, resistant to elevated temperatures material manufacturing, long service life.
3, stable working is shockproof: spool is spent under the guiding of cover inner surface in the effect lower edge of pressure medium, steadily rises or descends, the phenomenons such as steady and vibrations of having avoided working, and change easy.
4, open and close automatically:, need not to get final product opening and closing by elements such as other facilities or electrical equipment,
Compact conformation, easy to maintenance.
5, connected mode is various: can adopt connections such as welding, screw thread, flange.
Description of drawings
The apparatus structure schematic diagram is told in the automatic counnter attack of Fig. 1.
Wherein: 1, plug 2, housing 3, sealing ring 4, connection flower cover 5, spool 6, flower cover 7, valve seat 8, valve seat cover
The specific embodiment
With reference to the accompanying drawings the detailed in addition explanation of apparatus structure is told in automatic counnter attack described in the utility model below.
The automatic counnter attack of water injection well described in the utility model is told device and is by housing 2, plug 1, connects and spend cover 4, flower cover 6, spool 5, valve seat 7, valve seat cover 8 to constitute; Housing is one to constitute the disjunctor pipe of threeway by arm and straight tube, one end of straight tube has internal thread, plug 1 be a diameter and housing straight tube internal diameter be complementary above have externally threaded cylinder, plug precession pipe end blocks the housing pipe end, plug 1 outer wall and housing 2 inwalls are by sealing ring 3 sealings, plug 1 pipe is inner the diameter that has a circle groove on the sidewall boss less than the plug diameter, connection flower cover 4 one ends that have the hole on the wall are stuck in the boss groove, port is blocked by boss, tap is aimed in the hole that has on the wall, the other end that connects flower cover 4 is positioned at the other end of tap, outer diameter and straight tube internal diameter are complementary, inner diameter is complementary with flower cover 6 one end outer diameters, flower cover 6 other end outer walls are connected with valve seat cover inwall, valve seat overlaps 8 outer diameters and the straight tube internal diameter is complementary, be positioned at the water inlet end of straight tube, outer wall and straight tube inwall are sealed by sealing ring, valve seat 7 is an annulus, be embedded on the valve seat cover 8, spherical valve core 5 is sitting on the valve seat 7, is positioned at by connecting flower cover 4, flower cover 6, valve seat 7, in the space that valve seat cover 8 forms.
