Abstract
A novel polished rod sealer is composed of three parts: a sealing device, a universal adjusting device and a rod breakage anti-spraying device. The novel polished rod sealer is characterized in that: the sealing device comprises a nut, a straightening block, a material filling chamber and a block; the straightening block is equipped in the nut; the nut is screwed above the material filling chamber; the block is equipped below the material filling chamber; the universal adjusting device comprises an universal joint, an universal joint upper gland and a universal joint base; the universal joint is equipped on the universal joint base; the rod breakage anti-spraying device comprises an anti-spraying device, an anti-spraying ball gland and an anti-spraying ball; the sealing device is equipped above the universal adjusting device; the rod breakage anti-spraying device is equipped below the universal adjusting device; the anti-spraying ball and the anti-spraying gland are equipped in the rod breakage anti-spraying device. According to the novel polished rod sealer, the novel sealing material is adopted for sealing the polished rod. The universal adjusting device can better adjust mounting error between a well head and an oil extraction bunch for preventing eccentric wear. The rod breakage anti-spraying device can automatically seal the well head at first time for effectively preventing crude oil leakage.
Description
Technical field
The application's utility model relates to the corollary apparatus field of petroleum industry pumping unit, is to be used to be installed in have the sealing of the sealing material of employing, universal adjustment function, a kind of new type of rod sealing unit of disconnected bar blowout prevention function on the oil pumper well head.
Background technology
In the technology, the employed pumpingh well polish rod seal device in oil field generally all adopts packing_seal at present, and promptly packing gland with its compacting, is tightened then in rubber ring or waste and old V-belt, and this polish rod seal device is referred to as " packing box "; Just can prevent the crude oil leakage because packing need compress, then exist the degree of wear, the increase that strengthen polished rod and produce shortcomings such as power consumption, and then the production run cost of whole oil recovery is increased.
The utility model content
The application's utility model provides a kind of new type of rod sealing unit; This device is that innovation researched and developed and have that project organization is reasonable, the staff is easy to operate, adopt the sealing material sealing; The universal adjustment function, the new type of rod sealing unit of characteristics such as anti-disconnected bar function.
The application's utility model solves the technical scheme that its technical problem adopted: a kind of new type of rod sealing unit; Form by sealing device, universal adjusting device and disconnected bar blowout hookup three parts; It is characterized in that: said sealing device comprises nut, wiper block, filler storehouse and block; Wiper block is contained in the nut, and nut is screwed in top, filler storehouse, and block is installed in the below in filler storehouse; Said universal adjusting device comprises universal joint, universal joint upper press cover and gimbal base, and universal joint is installed on the gimbal base; Disconnected bar blowout hookup comprises blowout hookup, spray-proof ball gland and spray-proof ball; Sealing device is installed in the universal adjusting device top, and disconnected bar blowout hookup is installed in the universal adjusting device below, and spray-proof ball and blowout prevention gland are installed in the disconnected bar blowout hookup.
The utility model has adopted a kind of sealing material sealing, and this material is the mud shape, and it adopts injection gun to press in the injection polished rod sealer, and polished rod is sealed; Its universal adjustment function can better be regulated the installation deviation between well head and the oil recovery bundle, prevents the generation of eccentric wear; Its disconnected bar blowout prevention function can be sealed well head in the very first time of disconnected bar automatically, effectively prevents the crude oil leakage.
The application's utility model compared with prior art has the following advantages: it is unique, novel that this device has its design; And whole processing technology is easy; The user is easy to operate, and is easy to maintenance, and the polished rod wear rate is dropped to minimum; Also reduced simultaneously power consumption in the production run.
