Abstract
The utility model relates to a ring type sealing packing, consisting of an inner and an outer ring elastic body. One side sections of the inner and the outer ring elastic bodies(1, 2) are straight trapeziform, after buckling, one side section of the inner and the outer ring elastic bodies(1, 2) are rectangle; when in installation, a plurality of inner and outer ring elastic bodies(1, 2) is formed into a barrel-shaped elastic body. The multiple ring type sealing packing component provided by the utility model is combined with a plurality of pairs of ring sealing packing component which consists of an inner ring sealing body and an outer ring sealing body, and the cone surface of the inner ring sealing body and the cone surface of the outer ring sealing body are closely matched, the sealing performance is good and the service period is prolonged.
Description
(1) technical field:
The utility model relates to the ring formula sealed packing of rod member sealing place of valve rod, piston rod, rod-pumped well polished rod etc. and so on.
(2) background technology:
Sealing ring (packing) is all adorned in rod member sealing place of valve, piston rod and sucker rod motor-pumped well polished rod etc. and so on, especially the round-the-clock work of oilfield pumping well, the centering of the polished rod of rod-pumped well and well head packing box is generally relatively poor, along with polished rod increases finish decline service life, so the packing_seal difficulty is very big.The rod-pumped well Polish rod packing generally adopts artificial disc around rubber nylon rope method at present, and install and take a lot of trouble, the cost height, operative skill requires high, and the set-up time is long, and success rate is low, and application life is short.Particularly winter cold, the workman can not wear gloves during operation, hand freeze unusual pain.
(3) utility model content:
Technical problem to be solved in the utility model is at the problem that exists in the background technology, and provides a kind of combined labyrinth and carbon gland performance good ring formula sealed packing.
The invention for solving the technical problem can reach by following technical solution: it is become by inside and outside annular elastomer group, and the elastomeric lateral section of its inside and outside annular is a right-angled trapezium, and it is rectangle that inside and outside annular elastic body assembling fastens one lateral section, back; Form the tubular elastic body by how internal, outer ring elastic body during installation.
In such scheme, each annular solid ramp and horizontal plane angle are 40 °-70 °.The inside of interior annular elastomeric highly is less than or equal to the elastomeric outside of outer ring height.During installation, counterpart mutual dislocation on every pair of annular solid.Because how right install, seal between the monomer tightly, the sealing dislocation can reach purpose of design.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: the utility model is by polycycle sealed packing assembly, remedy above-mentioned deficiency, the formula of ring more than this kind packing_seal assembly, it is by interior ring seal and two of the external toroidal ring seals ring formula seal that partners, by many ring seal is made up again, constitute many rings formula sealed packing assembly.Its structure becomes to be characterised in that, interior ring seal is middle cone and the cylindrical shape that has cylindrical hole, external toroidal ring seal inside is the conical and cylindrical through hole of forming by one, is formed by the trochoidal surface of interior ring seal and external toroidal ring trochoidal surface to closely cooperate.
(4) description of drawings:
Accompanying drawing 1 is the utility model assembly drawing;
Accompanying drawing 2 is A-A sectional views on Fig. 1.
(5) specific embodiment:
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
Shown in accompanying drawing 1, it is fastened by inside and outside annular elastic body (1,2) and is a pair of packing, and a lateral section of its inside and outside annular elastic body (1,2) is a right-angled trapezium, and it is rectangle that inside and outside annular elastic body (1,2) assembling fastens one lateral section, back; Many internal, outer ring elastic body (1,2) composition tubular elastic bodys are arranged during installation.
In such scheme, each annular solid ramp 5 is 40 °-70 ° with horizontal plane angle.The inside of interior annular elastomeric 1 highly is less than or equal to the outside height of outer ring elastic body 2.During installation, counterpart on every pair of annular solid (3,4) mutual dislocation.
Claims (4)
1, a kind of ring formula sealed packing that relates to contains inside and outside annular elastic body (1,2), it is characterized in that:
One lateral section of a, inside and outside annular elastic body (1,2) is a right-angled trapezium, and it is rectangle that inside and outside annular elastic body (1,2) assembling fastens one lateral section, back;
Many internal, outer ring elastic body (1,2) composition tubular elastic bodys are arranged when b, installation.
2, packing according to claim 1 is characterized in that: 40 °-70 ° of each annular solid ramp and horizontal plane angles.
3, packing according to claim 1 is characterized in that: the inside of interior annular elastomeric (1) highly is less than or equal to the outside height of outer ring elastic body (2).
4, packing according to claim 1 is characterized in that: during installation, and counterpart on every pair of annular solid (3,4) mutual dislocation.
