Description
Technical field
The utility model relates to a kind of blowout prevention, the anti-energy-saving polished rod sealer of eccentric wear.
Background technology
The blowout preventer (polished rod sealer) that present rod-pumped well is adopted; Most packing-type packing seal structure that adopt must be shut down operation when the packing life cycle weak point of this structure, frequent change, replacing, and especially the eccentric wear well is changed more frequent; Careless slightly then causing emits the wet goods phenomenon to take place; Thereby cause labour intensity big, waste is serious, causes the certain economic loss.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of blowout prevention, the anti-energy-saving polished rod sealer of eccentric wear.
Its technical scheme is: blowout prevention, the anti-energy-saving polished rod sealer of eccentric wear; Weather strip imports overcoat and is connected with clamping cap, and clamping cap is provided with second handle, and clamping cap is through sealed tube and blowout prevention four-way; Anti-pressure cap is set between blowout prevention four-way and the lower prepared cap; The blowout-proof pressure cap both sides all connect handle chassis, plug the 3rd handle in the handle chassis, and lower prepared cap connects lower contact.
Blowout-proof pressure cap is connected with handle chassis through the blowout prevention bolt, and through nut handle chassis is fixed.
Comprise in the blowout prevention four-way that blowout prevention plug, anti-shower nozzle overcoat, spring pad, spring, second sealing ring, blowout prevention are extremely stifled.
Also comprise and set upright main body, set upright and comprise roller pad, roller pin, fixed screw and roller in the main body.
The beneficial effect of the utility model is:
1. compact conformation, rationally
This device is with tuningout base and sealed compartment, secondary seal cabin three big portions and replaced common rubber gate and all functions of packing box.
2. energy-efficient performance is good
The old belt that this device is crossed with used for oil extractor is done airtight and watertight padding, has replaced used in the past packings such as graphite, thereby accomplishes waste and old utilization again, reaches the purpose that reduces cost, and environmental protection and energy saving are played a very good protection.
3. good seal performance
The special abrasion resistance of belt has increased his sealing performance, has improved application life simultaneously.Through in the use in oil field contrast, adopt the packing of original blowout preventer must change twice well weekly, the sealing device of my company is installed after, can extend to 1 year.
4. has the tuningout function
Because this device is equipped with tuningout seat and erection device in the bottom, under the situation of polished rod bending, can carry out tuningout automatically, thereby guarantee the sealing of polished rod and belt, extend working time.
5. has the blowout prevention function
In the time of in polished rod breaks, comes off well, blowout hookup can instantaneous automatic sealing be prevented spray orifice under the suppressing of spring, stop in the well and the ejection of surface line backflow oil gas, thereby reaches the purpose of blowout prevention.
6. simple, convenient
This device can be realized not shutdown operation, after work a period of time, when as if discovery oil leakage phenomenon being arranged, need not the oil pumper that stops, and the belt of both can having screwed easily can reach the purpose of sealing.
7. raising oil recovery efficiency
Owing to accomplished not stop pumping operation certainly will reduce shutdown number of times and downtime, thereby increased crude output, and greatly reduced working strength of workers.

The specific embodiment
Referring to Fig. 1---Fig. 4, blowout prevention, the anti-energy-saving polished rod sealer of eccentric wear, weather strip imports overcoat and is connected with clamping cap; Clamping cap is provided with second handle; Clamping cap is provided with anti-pressure cap through sealed tube and blowout prevention four-way between blowout prevention four-way and the lower prepared cap, the blowout-proof pressure cap both sides all connect handle chassis; Plug the 3rd handle in the handle chassis, lower prepared cap connects lower contact.Blowout-proof pressure cap is connected with handle chassis through the blowout prevention bolt, and through nut handle chassis is fixed.Comprise in the blowout prevention four-way that blowout prevention plug, anti-shower nozzle overcoat, spring pad, spring, second sealing ring, blowout prevention are extremely stifled.Also comprise and set upright main body, set upright and comprise roller pad, roller pin, fixed screw and roller in the main body.
The key technical indexes of sealing device is:
