Two cams, the screens with both direction；
The screens of the both direction is stuck in injection well downhole flow regulator eccentric orfice for blanking plug and provides double insurance.
Preferably, the cam is connected to by clamp spring and axis pin in the blanking plug main body；
The clamp spring, for popping up or retracting the cam out of described blanking plug main body.
Preferably, the cam mechanism further includes：
Gland；
The fishing rod is passed through from the gland center；
The lower end of the gland is connect with the upper end of the blanking plug main body；
There is spring between the gland and the cam；
The spring pocket is outside the fishing rod.
Preferably, the lower part of the fishing rod has boss structure；
The boss structure, the lower end for undertaking the spring.
Preferably, the lower end attaching nut of the fishing rod；
The nut, thereon end face be used to undertake the lower end of the spring.
Preferably, two cams are disc cam.
Preferably, two cam coaxials are fixed in the blanking plug main body.
Preferably, the cam has groove structure；
The groove structure can only be moved for controlling the fishing rod along a direction of the cam contour.
Preferably, the rotation direction of two cams is opposite.
The beneficial effects of the utility model：The blanking plug of the application is due to using two cams, in the corruption of long-term injected media
It loses and using under abrasion condition, bidirectional cam realizes clamping functions from two different directions, increase blanking plug and be stuck in injection well downhole flow regulator
The success rate of eccentric orfice is capable of the service life of prolonged jam device；In addition, using the contraction of spring, smoothly by bidirectional cam
It is retracted in blanking plug main body, makes salvaging blanking plug easy and flexible.So the bidirectional clamping cam blanking plug delivers blanking plug
When, blanking plug is stuck in injection well downhole flow regulator eccentric orfice more insurance and secured, guarantee seperated layer water injection effect and testing efficiency.
Description of the drawings
