Abstract

The application invention relates to the field of matched devices for petroleum industry pumping equipment. A novel sealing device is arranged on a pumping unit well head, is sealed by using a novel sealing material, and has a universal adjustment function and a broken pole blowout prevention function. The device consists of three parts, namely a sealing device, a universal adjustment device and a broken pole blowout prevention device, and is characterized in that: the novel sealing material is used for sealing, is mud-like and is injected into a polished rod sealer by using an injection gun in a compression mode to seal a polished rod; mounting deviation between the well head and an oil extraction beam can be better adjusted by the universal adjustment function of the device to prevent eccentric wear; and the well head can be automatically sealed at the first time of pole breakage to effectively prevent crude oil leakage by the broken pole blowout prevention function of the device.

Description

A kind of sealing device

Technical field

The application's invention 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 sealing device 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.

Summary of the invention

The application invention provides a kind of new type sealing device, this device to be that innovation researched and developed and have that project organization is reasonable, the staff is easy to operate, adopt sealing material sealing, universal adjustment function, the new type sealing device of characteristics such as anti-disconnected bar function.

The application invents the solution technical scheme that its technical problem adopted: this device has all adopted a kind of brand-new design idea on project organization and operating principle.This device is made up of sealing device, universal adjusting device, disconnected bar blowout hookup three parts, all adopts the pipe thread of oil field standard to connect between three parts, and is easy for installation; It is characterized in that having adopted a kind of sealing material sealing, this material is the mud shape, and it adopts injection gun to press in the injection sealing device, 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 invention 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.
