Abstract
The utility model relates to an auxiliary device in the field of oil exploitation, in particular to a well mouth gate lead screw protecting device used on an oil well mouth. The technical scheme is that a coaxial sleeve with internal threads is arranged at the axis position of a U-shaped sleeve. The well mouth gate lead screw protecting device has the advantages of being simple in structure and capable of protecting a gate lead screw effectively, preventing water and dust, preventing damage and prolonging lead screw maintaining period and service life effectively.
Description
Technical field
The utility model relates to the servicing unit in field of petroleum exploitation, specifically relates to a kind of shaft collar leading screw protecting device using on well mouth of oil well.
Background technology
At present, the water injection well in oil field is generally used 250 model gate, testing, during the operations such as well-flushing, need repeatedly these gates of opening and closing, but, the damage of gate screw, make normally opening and closing of gate, had a strong impact on the continuously steady production in oil field, when keeping in repair or changing these gates, need to stop noting to water injection well, pressure release, required time is about 5-10 days, not only affect the output in oil field, also greatly increased worker's labour intensity, in order to protect leading screw not to be damaged, the general method adopting of oil recovery unit is to an elastic tape on screw set, although played certain dustproof effect, but be easy to be removed, and cannot protect well leading screw in the situation that of awful weather.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, develop a kind of shaft collar leading screw protecting device, be used for avoiding gate screw to be subject to dust, the erosion of rainwater, guarantee the normal opening and closing of gate, this utility model is simple in structure, easy for installation, time saving and energy saving, be easy to dismounting.
Its technical scheme is: at the axis place of a U-shaped sleeve, coaxial internal thread sleeve pipe is set.
The difference of the axial length of U-shaped sleeve and sleeve pipe is a bit larger tham the axial length of gate copper sheathing.
Beneficial effect: this utility model is simple in structure, can effectively protect gate screw, and waterproof is dustproof, tamper-proof, has effectively extended maintenance cycle and the application life of leading screw.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present embodiment.
The specific embodiment
Below in conjunction with accompanying drawing 1, be further described: at the axis place of a U-shaped sleeve 1, coaxial internal thread sleeve pipe 2 is set, sleeve pipe 2 screws with leading screw 3, rotation U-shaped sleeve 1, makes its openend dock with valve body 4.
In the situation that gate is closed completely, screw mandrel 3 only has end fraction to be exposed to outside, so the difference of the axial length of U-shaped sleeve 1 and sleeve pipe 2 is a bit larger tham the axial length of gate copper sheathing.
Claims (2)
1. a shaft collar leading screw protecting device, is characterized in that: at the axis place of a U-shaped sleeve, coaxial internal thread sleeve pipe is set.
2. shaft collar leading screw protecting device according to claim 1, is characterized in that: the difference of the axial length of U-shaped sleeve and sleeve pipe is a bit larger tham the axial length of gate copper sheathing.
