Exist in stifled ball removal process is adjusted, avoid flushing fluid that seepage, hoop component 4 and closeouts 6 occur with body 1
Junction seals.Specifically, outer wall of the hoop component 4 close to the first openend 41, and/or, chamber resettling 10 opens close to first
The inwall of mouth is provided with the first groove 44, and first seal 45 is provided with the first groove 44.Correspondingly, closeouts 6 are close to
The outer wall of two openends 42, and/or, chamber resettling 10 is provided with the second groove 62, the second groove close to the inwall of the second opening
Second seal 63 is provided with 62.
First groove 44 and the second groove 62 can be annular groove, and first seal 45 and second seal 63 specifically may be used
Think sealing ring made of the materials such as silica gel, rubber, plastics, the application is not construed as limiting to this.
Unidirectional flow-limiting mechanism 5 is used to limit the stifled ball of the tune having been introduced into chamber resettling 10 and flushing fluid backflow, tool
Body, Unidirectional flow-limiting mechanism 5 can have can be carried in hollow channel 46 opened under the flushing fluid effect for adjusting stifled ball so that
The first working condition that hollow channel 46 connects with chamber resettling 10, and can be in the presence of the flushing fluid in chamber resettling 10
The first openend 41 is closed to completely cut off the second working condition of hollow channel 46 and chamber resettling 10.
As shown in figure 1, when Unidirectional flow-limiting mechanism 5 is in the first working condition, its carrying in hollow channel 46
Opened in the presence of the flushing fluid of the stifled ball of tune, adjust the flushing fluid of stifled ball to flow to appearance by hollow channel 46 so as to allow to carry
Put chamber 10.
As shown in Fig. 2 when Unidirectional flow-limiting mechanism 5 is in the second working condition, it can have been introduced into accommodating cavity
Tune in room 10 is closed in the presence of blocking up ball and/or flushing fluid, so as to completely cut off the company between chamber resettling 10 and hollow channel 46
It is logical, prevent from adjusting stifled ball and flushing fluid to flow back.
In one embodiment, the Unidirectional flow-limiting mechanism 5 for meeting above-mentioned requirements can be including section with hollow channel 46
The baffle plate 51 that face shape is adapted, baffle plate 51 are pivotably attached on the first openend 41.The stifled ball of tune is carried in hollow channel 46
Flushing fluid can impose active force to baffle plate 51 so that it rotates, open the first openend 41, realize hollow channel
46 with the connection of chamber resettling 10.
Further, Unidirectional flow-limiting mechanism 5 can also include the connector 52 being connected with baffle plate 51, and connector 52 is substantially
Can be square block shape, and its quantity can be two, and two connectors 52 are oppositely arranged and are fixedly connected on baffle plate 51, two
The edge of baffle plate 51 is stretched out in one end of connector 52, and pin can be provided with the end at the edge of baffle plate 51 of the stretching
Hole.
A support member 7 can be had by being set on first openend 41, and support member 7 substantially can also be square block shape, set thereon
It is also equipped with pin-and-hole.Connector 52 is connected with support member 7 by bearing pin 8, is specifically as follows, and support member 7 is set relatively positioned at two
Between the connector 52 put, and the pin-and-hole alignment set on the pin-and-hole and support member 7 for making to set on two connectors 52, then
Bearing pin 8 is plugged in three pin-and-holes, you can realize the connection of connector 52 and support member 7.In this way, baffle plate 51 is rotatably connected on
On first openend 41, so that baffle plate 51 can be that pivotal point is rotated with bearing pin 8.
In addition, in order to avoid baffle plate 51 from being interfered in rotation process with the first openend 41 as far as possible, make baffle plate 51
Rotation has larger free space, and the first openend 41 forms ring-shaped step 9, support close to the portion concave of hollow channel 46
Part 7 is arranged on ring-shaped step 9.
Retaining piece 3 is used to filter to entering flushing fluid in chamber resettling 10, carrying the stifled ball of tune, prevents from adjusting
Stifled ball blocks the recovery approach of flushing fluid.In one embodiment, retaining piece 3 can curved tabular, retaining piece 3 can
To be fixedly connected on by supporting parts on the inwall of chamber resettling 10.Specifically, the retaining piece 3 of curved tabular is with relative
Both ends (left end and right-hand member anticipated as depicted in figs. 1 and 2), supporting parts are specifically as follows plate body, and its quantity can be two, two
One end of supporting parts is respectively fixedly connected with the both ends of retaining piece 3, and the other end is fixedly connected on the inwall of chamber resettling 10, so as to
Realize the fixation of retaining piece 3.
The sieve aperture 30 set on retaining piece 3 is used to supply flushing fluid fluid, and it is specifically as follows elongate holes, and quantity is more
Individual, multiple sieve apertures 30 can be evenly provided on retaining piece 3.
The inlet of the barrier flushing fluid recovery tube 2 at least in part of retaining piece 3, so adjust stop of the stifled ball in retaining piece 3
Remained under effect in chamber resettling 10, flushing fluid eventually flows to flushing fluid recovery tube 2 through sieve aperture 30, realizes recovery.
Preferably, retaining piece 3 forms complete barrier to the inlet of flushing fluid recovery tube 2.It is specifically as follows, along flushing fluid
The axial direction of recovery tube 2, the projection of flushing fluid recovery tube 2 are in the range of retaining piece 3.So, can be to greatest extent
Avoid adjusting stifled ball to enter flushing fluid recovery tube 2.
The specific work process of the stifled ball retracting device of tune of the application is as follows：
In use, hoop component 4 is connected with the test valve of well head, now baffle plate 51 is closed, i.e., single
The second working condition (as shown in Figure 2) is in current-limiting apparatus.Start anti-flushing well, carry and adjust the flushing fluid of stifled ball to push baffle plate open
51, i.e. Unidirectional flow-limiting device is in the first working condition (as shown in Figure 1), carries and adjusts the flushing fluid for blocking up ball through hoop component 4
Hollow channel 46 enter in the chamber resettling 10 of body 1.At this moment, stifled ball is adjusted due to the impulse force meeting of self gravitation and flushing fluid
Sink near the position of closeouts 6, flushing fluid flows out via retaining piece 3 and flushing fluid recovery tube 2.Due to retaining piece 3 and baffle plate
51 iris action, the tune in chamber resettling 10, which blocks up ball, to be entered in flushing fluid recovery tube 2, can not also return to hoop component
In 4 hollow channel 46.After backwash is completed, termination of pumping pressure release, closeouts 6 are unloaded, you can take out and all adjust stifled ball.
