Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described in detail.
By reference to the accompanying drawings shown in 1, a kind of sucker rod pump valve type helps takes out erection device, and comprising valve rod 1 and the valve pocket 2 being enclosed within valve rod 1 outside, is thin neck 13 in the middle of described valve rod 1, and it is outside that valve pocket 2 is set in thin neck 13, and described valve pocket 2 forms with valve rod 1 cavity 3 of pumping; The two ends up and down of described valve rod are respectively equipped with upper limit structure and lower limit structure, the below of described upper limit structure is provided with positioning guiding structure 12, described upper limit structure and valve rod 1 removably connect, and described valve pocket 2 is placed between positioning guiding structure 12 and lower limit structure; Described valve pocket 2 upper end ring surface is evenly provided with multiple stream oil groove 21.
Described upper limit structure is cylinder type hollow joint 4, and described joint 4 is connected on above valve rod 1 by thread bush; Described lower limit structure is annulus boss 11, and facilitating valve pocket 2 to be socketed on valve rod 1 like this, overall structure is simple.
Described joint 4 and the external diameter of positioning guiding structure 12 contact jaw are greater than the external diameter of positioning guiding structure 12; The external diameter of described annulus boss 11 is greater than the diameter of valve pocket 2 and annulus boss 11 contact jaw, described valve pocket 2 is placed between round boss 11 and directed guide frame 12, slide along positioning guiding structure 12, joint 4 and round boss 11 all play spacing effect to valve pocket 2.
Described valve rod is overall structure, by valve rod 1 is designed to overall structure, there is not the de-mouth problem that split connects, middle noose valve pocket 2 can mate with valve rod 1, thus make that valve pocket 2 thickens, intensity increases, and decreases the possibility falling block in the oil well course of work.
Described valve pocket 2 is made up of high-abrasive material, and its valve pocket 2 external diameter is greater than the maximum outside diameter of valve rod 1.
Described stream oil groove 21 is 2-4, and the quantity of this practical routine prioritizing selection stream oil groove 22 is 2.
For avoiding valve pocket 2 to occur scratching in forming process, the two ends of described valve rod 1 are equipped with transition arc, and the two ends of described valve pocket 2 are arc transition structure.The pipe aperture that its external diameter is sealed by correspondence determines.
Specific works process: as shown in Figure 1, is inserted in valve rod 1 by valve pocket 2 from one end of valve rod 1, is then threaded connection in the upper end of valve rod 1 by joint 4, by joint 4, realizes the upper limit of valve pocket 2 on valve rod 1; Round boss 11 on valve rod 1 realizes the lower limit to valve pocket 2, valve pocket 2 can to slidably reciprocate one end stroke at valve rod about 1, during up stroke, valve rod 1 moves down, valve pocket 2 moves, sealing surface at this moment on valve pocket 2 21 and round boss 11 away from, the endoporus between valve rod 1 with valve pocket 2 is opened and is communicated with, valve pocket 2 and valve rod 1 open mode, fluid enters cavity 3; During down stroke, valve rod 1 moves, valve pocket 2 moves down, and the sealing surface 21 at this moment on valve pocket 2 contacts with round boss 11, and the interior annular space realized between valve pocket 2 and valve rod 1 is closed, and fluid flows out from stream oil groove 22; By the movement of valve pocket 2 on valve rod 1, and the displacement being subject to round boss 11 and joint 4 limits, and realizes the open and close of the endoporus between valve pocket 2 and valve rod 1, completes whole oil pumping process.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
