Abstract
The utility mode discloses a pressure self-balancing type rubber gate. The upper end and the lower end of a gate base are provided with an upper pipe connector and a lower pipe connector respectively. The inner circumferential wall of the lower portion of the upper pipe connector is conical, and a driving gear and a centering gear are arranged inside the two sides of the middle of the gate base respectively. A sleeve is vertically arranged in the gate base between the two gears. The two sides of the sleeve are respectively and symmetrically provided with a gear rack structure, and the gear rack structures are meshed with the two gears respectively. Guiding bumps are vertically arranged on the two side walls of the upper portion of the sleeve respectively. Two pull rods are embedded into the guiding bumps respectively. The upper ends of the two pull rods are respectively connected with a conical-cylinder-shaped gate segment body, the cross section of the conical-cylinder-shaped gate segment bodies is semicircular, and the two conical-cylinder-shaped gate segment bodies move up and down in the axial direction of the gate base and enter the lower portion of the upper pipe connector to be matched with the inner conical circumferential wall for tightly extruding a polish rod. A by-pass pipe is arranged outside the gate base to communicate the upper pipe connector with the lower pipe connector.
Description
Technical field
The utility model relates to a kind of pressure self-balancing formula rubber gate.
Background technology
The replacing of the polish rod seal stuffing for pumping well on oil field at present all needs the rubber gate of packing box below to close the rear packing box filler operation of just changing.On oil field, rubber gate used is all that radially rubber core thrust is extrusion type sealed now.Its principle is to rely on symmetrical both sides rotation hand wheel, the rubber stopper that drives gate screw mandrel and screw mandrel front end to connect, oil pumping polish rod is radially pushed and both sides rubber deformation expanded and then play glue core outer fringe seal glue lock inner core, two glue in-core semicircle sealing polished rods, play the effect of sealing polished rod and rubber gate inwall annular space.Because this sealing means is the sealing of flat radial thrust, so will bestow the normal pressure that both sides sealing rubber is very large, therefore need to impose very large torsion to both sides handwheel, when operation, workman requires great effort very much.In addition, thus when operation both sides handwheel be that the polished rod after closing sealing of switch is respectively between two parties difficult, bad while adding packing packing is added in packing box.Because it is by powerful extruding front end rubber, so rubber is very easily squeezed broken, do not have sealing function.
Summary of the invention
The purpose of this utility model is to provide a kind of pressure self-balancing formula rubber gate, can close easily unlatching, is convenient for changing the operation of packing box filler, good sealing effect, and it is time saving and energy saving to use.
The purpose of this utility model is to realize like this, a kind of pressure self-balancing formula rubber gate, comprise gate seat, the two ends up and down of gate seat are being threaded connection respectively goes up lower pipe connection, it is conical that the bottom internal perisporium of upper union is, a driving gear and a righting gear are being set respectively in the both sides, middle part of gate seat, the rotating shaft outboard end of driving gear is arranging driving shaft, a sleeve pipe is vertically being set in the gate seat between two gears, on the two side of sleeve pipe, be symmetrical arranged respectively a rack structure, rack structure is meshed with two gears respectively, with the perpendicular vertical plane of two rack structure place planes in two side, sleeve pipe top on guiding projection is vertically being set respectively, two guiding projections slide up and down along the gathering sill arranging on internal surface of sleeve pipe respectively, in two guiding projections, setting-in a pull bar respectively, the upper end of two pull bars is connecting respectively a cone barrel flashboard body, the cross section semicircular in shape of cone barrel flashboard body, two cone barrel flashboard bodies axially move up and down and enter in said upper union bottom along gate seat and match with said conical internal perisporium, jam-packed polished rod, gate seat outer setting a bypass pipe, and upper lower pipe connection is communicated with.
As further improvement of the utility model, in said cone barrel flashboard body, there is a steel core body, steel core body is connected with said pull bar top, the coated rubber layer that arranging of steel core external body.
When the utility model is used, rotation by driving gear drives the sleeve pipe in gate seat to move up and down, when sleeve pipe upwards operation enter while matching with said conical internal perisporium in said upper union bottom, just jam-packed polished rod, thus be convenient for changing the operation of packing box filler.Because cone barrel flashboard body of the present utility model is the axially operation up and down along gate seat, so good sealing effect, it is time saving and energy saving to use.After packing box replacement, by bypass pipe, connect the liquid in the gate seat of the upper and lower two ends of sleeve pipe, equilibrium pressure, makes sleeve pipe be able to downward operation, thereby can close easily starting gate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view.
The specific embodiment
A pressure self-balancing formula rubber gate, as shown in Figure 1, comprises gate seat 8, and the two ends up and down of gate seat 8 are being threaded connection respectively goes up union 1 and lower pipe connection 5, and it is conical that the bottom internal perisporium of upper union 1 is.A driving gear 7 and a righting gear 3 are being set respectively in the both sides, middle part of gate seat 8, and the rotating shaft outboard end of driving gear 7 is arranging driving shaft.A sleeve pipe 6 is vertically being set in the gate seat between two gears, on the two side of sleeve pipe 6, be symmetrical arranged respectively a rack structure, rack structure is meshed with two gears 7,3 respectively, with the perpendicular vertical plane of two rack structure place planes in two side, sleeve pipe top on guiding projection 9 is vertically being set respectively, two guiding projections 9 slide up and down along the gathering sill arranging on internal surface of sleeve pipe respectively, guarantee that sleeve pipe 6 is along the axial operation of gate seat 8.Two interior setting-ins respectively of guiding projection 9 pull bar 10, the upper end of two pull bars 10 is connecting respectively a cone barrel flashboard body 12, the cross section semicircular in shape of cone barrel flashboard body 12, in said cone barrel flashboard body, there is a steel core body 11, steel core body 11 is connected with said pull bar 10 tops, the outside coated rubber layer that arranging of steel core body 11.Two cone barrel flashboard bodies 12 axially move up and down and enter in said upper union 1 bottom along gate seat and match with said conical internal perisporium, jam-packed polished rod; Gate seat outer setting a bypass pipe 4 with valve 2, upper lower pipe connection 1,5 is communicated with, in order to the pressure of balancing sleeve upper and lower sides.
