Detailed description of the invention
Now the utility model is further described by reference to the accompanying drawings.
See Fig. 1 to Figure 11; what Fig. 1 to Figure 11 showed is an embodiment of the present utility model; comprise top connection 1, sheath 2, spring 5, sealing shroud 11 and lower contact 12; wherein top connection 1, mandrel 4, spacer shell 6, sealing shroud 11 are connected successively with lower contact 12; sheath 2 is arranged on outside protection said structure; be provided with spring 5 between mandrel 4 and spacer shell 6, sealing shroud 11, lower contact 12 be respectively equipped with four liquid pass holes connected.
Comprise rail groove in addition and four be uniformly distributed track pin 10; Wherein, mandrel 4 is provided with the rail groove around its outer wall; One end of four track pin 10 is connected to the inwall of sealing shroud 11, and the other end inserts in rail groove respectively.In addition the rotation of bearing 8 auxiliary central spindle 4 is also had.The end of track pin 10 also has back-up ring 9.
See Fig. 8, the downside of described rail groove is limiting side, and described limiting side is provided with equally distributed stopper slot and lower guiding groove; The upside of described rail groove is oriented side, and described oriented side is provided with locating slot and upper guiding groove.
See Figure 11, described stopper slot is arc-shaped, and described lower guiding groove is linear; Locating slot is arc-shaped, and upper guiding groove is linear; In the present embodiment, the central angle from the bottom of a locating slot to the bottom of adjacent locating slot is 45 °; Be provided with guiding groove therebetween.Central angle from the bottom of a stopper slot to the bottom of adjacent stopper slot is 45 °, is provided with lower guiding groove therebetween.Wherein, lower guiding groove is just to locating slot, and upper guiding groove, just to stopper slot, result in formation of the structure of " dislocation ", can reach technical purpose in rotary course.
See Fig. 4, described mandrel 4 sidewall is provided with four and is uniformly distributed, can connects the through hole of liquid pass hole along with mandrel 4 rotates.
Be the present embodiment original state see Fig. 1, Fig. 1, track pin 10 is positioned at a locating slot of rail groove.The through hole for fluid on mandrel is just also closed by it the inwall of sealing shroud, achieves " face sealing ", has effectively intercepted the output of oil gas.
In use, upwards withstand mandrel 4 by the opener of manual control, described mandrel 4 can push up (and spring 5 extrudes spacer shell 6) to upside after stressed.In the process that mandrel 4 moves upward as straight line, track pin 10 can leave the locating slot in original state, when arriving the lower guiding groove just to the locating slot of original state, track pin 10 can drive mandrel 4 be rotated counterclockwise (upward direction is seen) by this rectilinear lower guiding groove, track pin 10 enter adjacent, on clockwise direction in first locating slot.Now, mandrel have rotated 45 °, and through hole has rotated to the position can connecting liquid pass hole, and now high-temperature oil gas upwards exports ground to and exploits.
After completing exploitation, remove opener, namely spring 5 starts to reset.Now mandrel 4 carries out rectilinear motion downwards, and track pin 10 leaves stopper slot simultaneously.When track pin 10 withstands guiding groove, under the effect of upper guiding groove, guide mandrel 4 to try again 45 ° be rotated counterclockwise (upward direction is seen).After rotation completes, the relation of through hole and liquid pass hole gets back to original state (mandrel 4 has been rotated counterclockwise 90 °).
Reciprocal successively, can go round and begin again aforesaid operations.
See Fig. 6, Figure 10, also comprise bellows component 3.Because outside exists high pressure, high pressure can transfer to sealing shroud 11 along liquid pass hole; Easily cause the problems such as dislocation, so the preferred bellows component 3 of the present embodiment withstands sealing shroud 11 by stock, between stock and sealing shroud 11, be also provided with cushion cover 7 carry out auxiliary completing technology effect.
See Fig. 5, be provided with four at the equally distributed keyway pin 13 of its sidewall as the preferred sidewall in lower contact 12, described keyway pin 13 stretches out the sidewall of lower contact 12 respectively; Rotary stopper groove is provided with at the correspondence position of mandrel 4; Keyway pin 13 inserts in rotary stopper groove and can be fixed to avoid it to rotate to mandrel 4.
Above by reference to the accompanying drawings and embodiment describe embodiment of the present utility model; the structure that embodiment provides does not form restriction of the present utility model; in this area, those skilled in the art can adjust according to needs, make various distortion within the scope of the appended claims or revise all in protection domain.
