Abstract
The utility model relates to an automatic anti-pollution device by releasing a polished rod, particularly an automatic anti-pollution device by releasing a polished rod used for a well mouth of an oil-extracting well for the oil-producing work of oil industry, which comprises a main body 1, an orienting pin bolt 2, an abrasion-resistant pad 3, a spring jia 5, a sheath 6, a sliding sleeve 7, a spring yi 8, a sealing ball 9, a split ring 10 and a ball seat 11, wherein the ball seat 11 is in screw connection with the inner cavity of the main body 1; the right end of the main body 1 is in screw connection with the sheath 6; the orienting pin bolt 2 is arranged at the lower part of the right side of the main body 1; the sliding sleeve 7 is connected by screw nails with the abrasion-resistant pad 3; the spring jia 5, the sealing ball 9 and the spring yi 8 are arranged in the sliding sleeve 7; the split ring 10 is arranged at the mouth of the sheath 6. The automatic anti-pollution device by releasing the polished rod has reliable performance and after the polished rod releases, the sealing ball is pushed upward towards the ball seat under the combined action of the pushing forces of the spring jia and the spring yi and automatically prevents oil and gas flow from overflowing from a blowout-preventing box. The abrasion-resistant pad made of high-strength nonmetallic abrasion-resistant material has the advantages of long service life and convenient installation and replacement. The automatic anti-pollution device by releasing the polished rod has the advantages of reasonable design, simple and compact integral structure, beautiful appearance, less investment and convenient installation, disassembly, process and assembly.
Description
Technical field
The polished rod that the utility model provides a kind of petroleum industry oil producing operation rod-pumped well well head to use breaks and takes off automatic environmental control system.
Background technology
At present, the rod-pumped well well head generally all adopts common wellhead polish rod sealer on the oil field, because its structural defective, prevents after not having that polished rod is disconnected and taking off that crude stream from losing and pollute function.In the oil recovery manufacturing process, polished rod is disconnected to be taken off phenomenon and happens occasionally, if polished rod is in case disconnected taking off, disconnected taking off a little extracted out polished rod sealer with the top polished rod by horse head, disconnected taking off a little with lower part polished rod and rod string whereabouts, the gas stream that oil well is interior and measuring station ground main line is poured out just comes up from the ejection of blowout prevention box or the race of polished rod sealer, cause a large amount of losses of crude oil and well site surrounding environment to pollute, make troubles for oil field field control and the work of removing contamination, increase cost investment and polluted damages, directly affected the raising of oil field oil recovery economic benefit.
Summary of the invention
The purpose of this utility model is to provide a kind of rod-pumped well in process of production, polished rod is in case after disconnected the taking off, can either prevent effectively automatically that crude oil runs off and environment pollution, can break with the matching used polished rod of common wellhead polish rod sealer again and take off automatic environmental control system.
The purpose of this utility model is achieved in that
Comprise main body 1, directed pin 2, wear-resistant pad 3, spring first 5, sheath 6, sliding sleeve 7, spring second 8, ball sealer 9, split ring 10, ball seat 11, ball seat 11 is connected with main body 1 thread in inner cavity, main body 1 right-hand member is threaded with sheath 6, main body 1 lower right side is provided with directed pin 2, sliding sleeve 7 and wear-resistant pad 3 are connected by screw, establish spring first 5, ball sealer 9, spring second 8 in the sliding sleeve 7, split ring 10 is located at the oral area of sheath 6.
The utility model also adopts following technical scheme:
Main body 1 is the cylindrical structure that communicates up and down, and upper/lower terminal is provided with box screw thread and pin thread screw thread.
The left part of main body 1 is dead stifled.
Sliding sleeve 7 bottoms are provided with guide slot.
The left side of sliding sleeve 7 is a tubular construction vertically upward, and the right side is a level tubular construction to the right.
Advantage of the present utility model is: 1. automatic environmental control system dependable performance, polished rod is disconnected take off after, ball sealer is upwards pushed ball seat under the acting in conjunction of spring first, second thrust, prevent from automatically that gas stream from running from the blowout prevention box to come up.2. wear-resistant pad adopts the high strength nonmetallic wear-resistant material, and the life-span is long, and it is convenient to install and change.3. disconnected to take off automatic environmental control system reasonable in design for polished rod, and overall structure is simply compact, good looking appearance, and small investment, installing/dismounting is easy to assembly with processing.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, main body 1 is the cylindrical structure that communicates up and down, on, following two ends are provided with box screw thread and pin thread screw thread, so that link with blowout prevention box and rubber gate, the box screw thread is connected with the main body thread in inner cavity to have the ball seat 11 that Open Side Down, main body 1 left end is threaded with main body 1 for dead blocking up, right-hand member is threaded with sheath 6, and lower right side is provided with directed pin 2, and sliding sleeve 7 bottoms are provided with guide slot, sliding sleeve 7 and wear-resistant pad 3 are connected by screw, the left side of sliding sleeve 7 is a tubular construction vertically upward, in establish spring first 5 and ball sealer 9, the right side is a level tubular construction to the right, in establish spring second 8, split ring 10 is located at sheath 6 oral areas.
Take off in the middle of the blowout prevention box and rubber gate that automatic environmental control system is installed in polished rod sealer polished rod is disconnected, polished rod passes from automatic environmental control system mesopore, during the pumping of oil well ordinary production, ball sealer under the effect of spring first near main body inner wall, wear-resistant pad under the effect of spring second near polished rod, keep relative equilibrium, polished rod is disconnected to be taken off automatic environmental control system and is in the unlatching duty.After unexpected disconnected the taking off of polished rod, disconnected take off a little above polished rod and extracted out automatic environmental control system by horse head, break and take off a little under action of gravity, to fall with lower part polished rod and rod string, the wear-resistant pad disequilibrium and under spring second thrust to moving away from the sheath direction, along with sliding sleeve to moving away from the sheath direction, ball sealer is upwards pushed ball seat and sealed ball seat under spring first thrust, avoid crude oil from ejection of blowout prevention box and loss, realize automatic antipollution purpose.
