It includes outer barrel, inner cylinder, adjust fuse, bridge-type pipe nipple, the inner cylinder upper semisection is stretched into outer barrel to be connected with outer barrel, installation inside inner cylinder
Adjust fuse, the inner cylinder and adjust fuse be attached by bridge-type pipe nipple, the inner cylinder, adjust fuse open up and meanwhile with
The radial hole of bridge-type pipe nipple connection.
The inner tank theca is socketed anti-stab piston, and the inner cylinder also opens up the pressure transmission hole for being connected to anti-stab piston cavity, prevents
The lower spring of piston connection is pierced, there is annular space between the inner cylinder and outer barrel, which connects with the radial hole that inner cylinder opens up,
And the pressure transmission hole of the annular space lower end as outer barrel blocks pressure transmission hole under the anti-stab piston normality.
The adjusting outside core installs spring, and upper spring upper and lower side installs pressure ring and baffle ring respectively.
The adjusting fuse is sealed with bridge-type pipe nipple using cone structure.
The outer barrel upper end connects top connection, and inner cylinder lower end connects lower contact, the adjusting fuse lower end by connector sleeve
Connect anti-rotation fuse, the connection lower contact of anti-rotation fuse lower end.
Compared to the prior art, the invention has the advantages that：
1st, set and survey the matched bridge type mechanism of conditioning technology with collecting type, realize the small single-layer direct-reading type under the conditions of fluence
It surveys and adjusts；
2nd, the conical surface seal adjusting mechanism that PEK materials-Steel material is combined heightens sealing and the verticity of injection well downhole flow regulator；
Adjustment hole uses " diamond shape+circle " combined shaped simultaneously, realizes that water distribution quantity is effectively adjusted；
The 3rd, anti-stab mechanism is set, reduce the erosion of injection well downhole flow regulator apopore, extends injection well downhole flow regulator service life.
Description of the drawings
Fig. 1 is the structure diagram of the long-acting injection well downhole flow regulator of the small flow of bridge type mechanism of the present invention；
Fig. 2 is the partial enlarged view of Fig. 1.
In figure：Top connection 1, outer barrel 2 adjust fuse 3, are pressure ring 4, upper spring 5, inner cylinder 6, baffle ring 7, bridge-type pipe nipple 8, anti-stab
Piston 9, lower spring 10, anti-rotation fuse 11, connector sleeve 12, lower contact 13, pressure transmission hole 14.
Specific embodiment
Detailed description for the present invention and technology contents, cooperation description of the drawings it is as follows, however attached drawing only provide reference with
Purposes of discussion is not used for being any limitation as the present invention.
According to Fig. 1-2, the long-acting injection well downhole flow regulator of the small flow of bridge type mechanism including outer barrel 2, inner cylinder 6, adjusts fuse 3, bridge-type pipe nipple
8, the inner cylinder upper semisection is stretched into outer barrel to be connected with outer barrel, installation and adjustment fuse inside inner cylinder, the inner cylinder and adjusting fuse
It is attached by bridge-type pipe nipple, the inner cylinder adjusts the radial hole that fuse is opened up while connected with bridge-type pipe nipple.In described
Drum outer wall is socketed anti-stab piston 9, and the inner cylinder also opens up the pressure transmission hole 14 for being connected to anti-stab piston cavity, and anti-stab piston connects
Connect lower spring, 10, there is annular space, which connects with the radial hole that inner cylinder opens up, and the ring between the inner cylinder and outer barrel
Pressure transmission hole of the empty lower end as outer barrel blocks pressure transmission hole under the anti-stab piston normality.The adjusting outside core installs bullet
Spring 5, upper spring upper and lower side install pressure ring 4 and baffle ring 7 respectively.The adjusting fuse is carried out close with bridge-type pipe nipple using cone structure
Envelope.The outer barrel upper end connects top connection 1, and inner cylinder lower end connects lower contact 13, the adjusting fuse lower end by connector sleeve 12
