Brief description of the drawings
Fig. 1 is the half-sectional structural representation of polished rod sealer of the embodiment of the present invention.
Embodiment
As illustrated, a kind of polished rod sealer, including housing, casing center have for oil production equipment polished rod pass through it is interior
Chamber, housing is connected through a screw thread and constituted by upper shell 6, lower house 11, and the inner chamber top of upper shell 6, the inner chamber bottom of lower house 11 are set
It is equipped with the upper gas-tight silo inside limited step composition gas-tight silo, upper shell 6 and is mounted with inside seal 2, lower house 11
Lower seal 10 is mounted with lower gas-tight silo；It is upper in gas-tight silo that elastic expansion pad is provided between seal 2, lower seal 10；
The top of upper shell 6 is provided with conical oil storage pool 1；Elastic expansion pad can clamp pressure between plate upper pressure pad, lower pressure pad
Contracting spring 5 is constituted, it can also be provided that the cylindrical structure constituted that is nested by upper pressure pad 4, lower pressure pad 7, compression spring 5 is disposed
In upper pressure pad 4, the inner chamber of lower pressure pad 7, the upper upper end of pressure pad 4, lower pressure pad 7 push down compression spring 5 inside lower end by limited step；On
The upper surface of pressure pad 4, the lower surface of lower pressure pad 7 all include one section of inner conical surface, one section of male cone (strobilus masculinus)；Upper shell 6, lower house 11 are threadedly coupled
Position is provided with locking nut 9；Rotary handle 3 is provided with outside upper shell 6；The lower end of lower house 11 is provided with mounting flange.
The polished rod sealer of the embodiment of the present invention, upper shell 6, lower house 11 is connected through a screw thread composition center has inner chamber
Housing, the true polished rod of oil production equipment passes through housing cavity, and housing is fixedly mounted by the flange plate structure of the bottom of lower house 11, shell
Body need to only be installed when assembling with two sections, and simple in construction, installation procedure is simple；The inner chamber top of upper shell 6, the inner chamber of lower house 11
Bottom, which is set, is filled with encapsulant composition sealing in the gas-tight silo that the housing cavity between limited step, limited step is constituted
Body, encapsulant is easy for installation, sealed reliable.
It is for lower seal in upper gas-tight silo inside upper shell 6 in the lower gas-tight silo inside upper seal 2, lower house 11
10；Upper in gas-tight silo that elastic expansion pad is provided between seal 2, lower seal 10, upper seal 2, lower seal 10 are close
Push down elastic expansion pad；Elastic expansion pad is be nested by upper pressure pad 4, lower pressure pad 7 cylindrical structure constituted, compression spring 5
Pressure pad 4, the inner chamber of lower pressure pad 7 are placed in, the upper upper end of pressure pad 4, the lower end of lower pressure pad 7 are internally provided with spring retainer step, compressed
Spring Card is mounted between limited step；When upper seal 2, lower seal 10 are worn as oil production equipment is continuously run, compression
Spring 5 can stretch therewith, and promote upper pressure pad 4, lower pressure pad 7 to be closely pressed against upper seal 2, lower sealing by limited step
Seal 2, the wear extent of lower seal 10, upper pressure pad 4, the continuous close of lower pressure pad 7 on body 10, the energy continued compensation of compression spring 5
Seal 2, lower seal 10 are pressed against, sealing effectiveness continues constant；The upper upper surface of pressure pad 4, the lower surface of lower pressure pad 7 all include
One section of inner conical surface, one section of male cone (strobilus masculinus), the cone-apex angle that upper pressure pad 4, lower pressure pad 7 are made up of two sections of conical surfaces be pressed against upper seal 2,
Lower seal 10, further improves sealing property；The upper male cone (strobilus masculinus) of pressure pad 4 is nested with the lower inner conical surface of pressure pad 7 mutual cooperation to be installed,
So that compression spring stress equalization, stretches steady, sealing property is stable.
Upper shell 6, the screw connection point of lower house 11 set and are provided with rotary handle 3 outside locking nut 9, upper shell 6,
The lower end of lower house 11 is fixedly mounted by mounting flange and oil production equipment；Lower seal 10 inserts lower gas-tight silo in lower house 11
Afterwards, then successively lower pressure pad 7, compression spring 5, upper pressure pad 4, upper seal 2 are laid, last operation rotary handle 3 leads to upper shell 4
Threaded connection and the close installation of lower house 11 are crossed, compression spring 5 is tightly compressed minimum dimension, easy for installation, sealing is steady
Reliably；Few remaining crude oil in part runs the conical oil storage pool 1 that the top of upper shell 6 is accumulated in after supreme case top with polished rod
In, will not leakage pollution environment, the crude oil of the balling-up of oil storage pool 1 can be with recycling.
The polished rod sealer of the present invention, installation constitutes main body with upper shell, lower house two-stage structure, simple in construction,
It is convenient for installation and maintenance, by the spring swell increment of elastic expansion pad come the wear extent of compensation sealing body, good sealing effect, Bu Huifa
