Abstract

Strip-shaped compound sealing packing comprises an upper elastic body (1), a fiber rope (2) and a lower elastic body (3). The strip-shaped compound sealing packing is characterized in that the upper elastic body (1) and the lower elastic body (3) are both of a long-strip-shaped banded structure, the cross section of the upper elastic body (1) is of a triangular structure, the cross section of the lower elastic body (3) is of a V-shaped structure, and the upper elastic body (1) and the lower elastic body (3) are matched with the cross sections to form a rectangle. According to the strip-shaped compound sealing packing, the upper strip-shaped elastic body with the triangular cross section and the lower strip-shaped elastic body with the V-shaped cross section form a sealing packing component in a buckling mode, a spiral cylindrical sealing body is formed after the sealing packing component is mounted, after the sealing packing component is abraded, the sealing packing component is pressed through a packing pressing cap to generate extrusion and novel sealing on the buckling face, the sealing property is good, service life is long, time and labor are saved, and normal production of an oil well is guaranteed.

Description

Strip compound seal packing
Technical field
The utility model relates to the strip compound seal packing of rod member sealing place of valve rod, piston rod, oilfield pumping well polished rod etc. and so on.
Background technique
Sealed packing all is equipped with in rod member sealing place of valve rod, piston rod, oilfield pumping well polished rod etc. and so on, oilfield pumping well work under bad environment in the open air particularly, bearing the erosion of dust storm sleet, work without cessation continuously, there are deviation in the polished rod of pumping well and the centering of wellhead packing box, along with the polished rod prolongation surface finishment decline of service life, the packing_seal difficulty is large.Packing is the single ring structure of rubber material at present, during installation, need packing is cut 30-45 ° of otch, and the many poor sealing performances of opening, working life is short, and replacing is wasted time and energy, and affects oil well production.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of strip compound seal packing.
The utility model is realized by following technical proposals:
The utility model comprises: upper elastomer, textile rope, lower elastomer.Upper elastomer, the lower elastomer of its strip compound seal packing are the bar-shape structure, and upper elastomer transverse section is triangular structure, and lower elastomer transverse section is " V " shape structure, and upper elastomer coordinates the transverse section to form rectangular with lower elastomer.
Strip compound seal packing in above-mentioned strip compound seal packing is provided with textile rope in elastomer, lower elastomer on it, to increase antiwear property.
The beneficial effects of the utility model are: be that triangle and two upper and lower involutory strip elastomers of " V " shape form the sealed packing assembly by its cross section, form the spiral tubular seal after installing, wearing and tearing make involutory surface produce extruding by the packing pressure cap pressurization and reseal, good seal performance, long service life, time saving and energy saving, the assurance oil well is normally produced.
Description of drawings
Fig. 1-the utility model cross-sectional configuration schematic diagram.
In figure, 1. go up elastomer, 2. textile rope, 3. descend elastomer.
Embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
Strip compound seal packing is comprised of upper elastomer 1, textile rope 2, lower elastomer 3.On the bar-shape of its strip compound seal packing under elastomer 1 triangular cross-section and bar-shape elastomer 3 " V " shape transverse section to synthesizing the rectangular transverse section, the termination is cut into 30 ° of oblique angles, the up time dials enters in packing box to compress, equally tail end is cut into 30 ° of oblique angles, tighten packing box pressing cap and get final product.

Claims (2)

1. a strip compound seal packing, comprising: upper elastomer (1), textile rope (2), lower elastomer (3); It is characterized in that: the upper elastomer (1) of described strip compound seal packing, lower elastomer (3) are the bar-shape structure, upper elastomer (1) transverse section is triangular structure, lower elastomer (3) transverse section is " V " shape structure, and upper elastomer (1) coordinates the transverse section to form rectangular with lower elastomer (3).
2. strip compound seal packing according to claim 1, is characterized in that: be provided with textile rope (2) in described upper elastomer (1), lower elastomer (3).
