This utility model reasonable and compact in structure, it installs the combination of control pipe with pressure additional by former packing box replaces with packing_seal box, can realize the with pressure of polished rod is lifted up, the pressure venting in control pipe with pressure can be will be located in after polished rod has lifted up by setting up relief valve, consequently facilitating the replacing of light pipe, the upper line displacement of polished rod can being limited by limiting component, hoop one-tenth buffering and crashproof effect can being docked by setting up buffer spring, thus extending the service life of polished rod and box cupling and limiting component；Adopting this utility model to carry out polished rod operation of changing with pressure, easy to operate, time saving and energy saving, convenient and swift, simple in construction, production cost is low, and safety coefficient is high, not easily contaminated environment, and stability is high, not easily loses efficacy。
Accompanying drawing explanation
Accompanying drawing 1 is that this utility model most preferred embodiment master in a state of use looks broken section structural representation。
Coding in accompanying drawing is respectively as follows: 1 and controls pipe for pressure, and 2 is relief valve, and 3 is packing_seal box, and 4 go out pipe for side, and 5 is limiting component, and 6 is external screw thread, and 7 is buffer spring, and 8 is polished rod, and 9 is box cupling。
Detailed description of the invention
This utility model, not by the restriction of following embodiment, can determine specific embodiment according to the technical solution of the utility model and practical situation。
In this utility model, for the ease of describing, the Butut mode that the description of the relative position relation of each parts is all according to Figure of description 1 is described, as: the position relationship of forward and backward, upper and lower, left and right etc. is based on what the Butut direction of Figure of description was determined。
Below in conjunction with embodiment and accompanying drawing, this utility model is further described:
As shown in Figure 1, this polished rod well head controller that changes with pressure includes control pipe 1 with pressure, relief valve 2 and can seal the packing_seal box 3 of mobile polished rod 8, the bottom of packing_seal box 3 is installed with control pipe 1 with pressure, the sidewall of control pipe 1 with pressure is provided with the side that endoporus communicates with control pipe 1 inner chamber with pressure and goes out pipe 4, go out in side and pipe 4 is installed with relief valve 2, being provided with in control pipe 1 with pressure and can pass through the limiting component 5 that spacing connecting hoop 9 limits the upper line displacement of polished rod 8, the lower end outside of control pipe 1 with pressure has the external screw thread 6 that can link together with well head。In use, need to first closing the rubber gate that well head carries, then be taken off by the former packing box installed on well head, and be installed on well head by this utility model, now the upper end of polished rod 8 should pass from bottom up of the present utility model；Then the rubber gate of well head can be opened, thus what carry out polished rod 8 lifts up operation, when the box cupling 9 being arranged on polished rod 8 go upward to the bottom being against limiting component 5 by its spacing time, polished rod 8 will go upward to extreme position, now can close the rubber gate of well head, to realizing envelope press operation in well；Finally can first open relief valve 2 and discharge the pressure in control pipe 1 with pressure, after earth pressure release is complete, packing_seal box 3 can be passed through the polished rod 8 lifted up is replaced, relief valve 2 can cut out after having changed, and open the rubber gate of well head, the polished rod 8 newly changed can be transferred to predeterminated position；Afterwards if necessary, this utility model is taken off by the rubber gate that can be again switched off well head, and is changed by former packing box and can carry out subsequent operation；Adopting this utility model to carry out polished rod 8 operation of changing with pressure, easy to operate, time saving and energy saving, convenient and swift, simple in construction, production cost is low, and safety coefficient is high, not easily contaminated environment, and stability is high, not easily loses efficacy。According to demand, relief valve 2 and packing_seal box 3 all can adopt existing known technology。
According to actual needs, above-mentioned polished rod 8 well head controller that changes with pressure can be made further optimization and/or improvements:
As shown in Figure 1, it is provided with, in the control pipe 1 with pressure of corresponding limiting component 5 lower position, the buffer spring 7 being set in outside polished rod 8。In use, lift up in process at polished rod 8, the bottom that the end face of box cupling 9 will first contact with buffer spring 7, and drive buffer spring 7 to go upward to its end face to be against the bottom of limiting component 5, then will start to compress buffer spring 7 to its deformation limit, at this moment the weight indicator load promoting system rises, it is possible to prove that polished rod meets soldier and may certify that polished rod box cupling has been enter into band pressure controller。Now polished rod 8 will go upward to its extreme position；Can play buffering and crashproof effect while the upper line displacement of restriction polished rod 8 by setting up buffer spring 7, effectively reduce the External Force Acting that box cupling 9 is subject to, thus protecting the thread between box cupling 9 and polished rod 8, extending respective service life。
As shown in Figure 1, the bottom of limiting component 5 is fixed in the upper end of buffer spring 7。So can make this utility model when mounted can be convenient laborsaving。
As shown in Figure 1, limiting component 5 is positioned at side and goes out the top of pipe 4。In use, when polished rod 8, box cupling 9 enter band pressure controller, closing the rubber gate of mouth of pumped oil well self, cut-out pressure enters controller。Make the operation changing polished rod 8 more smooth；According to demand, when polished rod 8 goes upward to extreme position, the upper end of box cupling 9 is positioned at side and goes out the top of pipe 4, so can ensure that polished rod 8 can be trapped in fluid in control pipe 1 with pressure without touching when changing。
As shown in Figure 1, limiting component 5 is spacing ring, is provided with spacing ring on the inwall of control pipe 1 with pressure, the internal diameter of the spacing ring external diameter more than polished rod 8 and the external diameter less than box cupling 9。Spacing ring can connect as one with control pipe 1 with pressure, and both are integrated or adopt other existing known fixed form also by being welded and fixed, and thus can meet its spacing demand。
As shown in Figure 1, limiting component 5 is limited block, circumferentially has at least two limited block, the inscribed circle diameter of the medial surface of the institute's restraining position ring block external diameter more than polished rod 8 and the external diameter less than box cupling 9 on the inwall of control pipe 1 with pressure。Limited block can connect as one with control pipe 1 with pressure, and both are integrated or adopt other existing known fixed form also by being welded and fixed, and so can meet spacing demand。According to demand, all limited blocks can be uniformly distributed along the circumference with on the inwall of control pipe 1 with pressure。
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations。
