Abstract
The utility model relates to a bottom valve of an oil drilling fluid solid control system, and particularly relates to the bottom valve of the oil drilling fluid solid control system. The bottom valve of the oil drilling fluid solid control system comprises a shell (1) and a valve core (2), wherein the valve core (2) is arranged inside the shell (1) in a sliding manner; a valve rod (3) is arranged on the valve core (2); a thread is arranged on the valve rod (3); and the valve rod (3) is connected with a first sleeve (4) via the thread. The bottom valve of the oil drilling fluid solid control system is characterized in that the thread opposite to the turning direction of the thread of the valve rod (3) is arranged at the wall of an outer drum of the first sleeve (4); a second sleeve (5) is connected with the first sleeve (4) through the thread at the wall of the outer drum; the second sleeve (5) is fixedly arranged on the shell (1); and the fluctuation speed of the valve core (2) is twice that of the bottom valve driven by a traditional single screw. Thus, the time of opening and closing the bottom valve is one half of the bottom valve of the traditional single screw within the same switching path; the labor intensity is reduced; and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of petroleum drilling fluid solid controlling system equipment, particularly a kind of petroleum drilling fluid solid controlling system bottom valve.
Background technology
In petroleum drilling operation, bottom valve is widely used in trial boring operation drilling fluid low pressure recycle system, in the drillng operation circulation of drilling fluid, the gauge tap of the suction line that bottom valve is slush pump, concrete pump and shear pump, so, in current low-pressure drilling fluid circulation, all there is a fairly large number of bottom valve.
Existing bottom valve is for adopting single screw drive to realize moving up and down of bottom valve spool, realize the switch of bottom valve, the screw driven bottom valve of this list is simple in structure, in order to make screw drive, can realize auto-lock function, so need to single screw drive be set to fine pitch.When adopting the fine pitch screw drive, because pitch is little, described screw drive is slow, thereby caused need to be longer time could realize the switch motion of switch bottom valve, in actual use, affected greatly the efficiency of drillng operation, while especially processing the underground emergency accident, because the bottom valve switch motion is slow, easily cause security incident; In addition, the single screw drive of this fine pitch, because pitch is little, when handwheel rotates a circle, less height can only be mentioned or reduce to spool, so operation labour intensity is large when the operation bottom valve.
So need badly at present and a kind ofly can realize quick opening and closing and operation labour intensity little bottom valve.
The utility model content
Goal of the invention of the present utility model is: the switch motion existed for existing petroleum drilling fluid solid controlling system bottom valve is slow and operate the large problem of labour intensity, provides a kind of and can realize quick opening and closing and the little petroleum drilling fluid solid controlling system bottom valve of operation labour intensity.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of petroleum drilling fluid solid controlling system bottom valve, comprise housing 1 and be slidably arranged in the spool 2 in described housing 1, be provided with valve rod 3 on described spool 2, be provided with screw thread on described valve rod 3, described valve rod 3 first sleeve 4 that has been threaded, be provided with the screw thread contrary with the thread rotary orientation of described valve rod 3 on described the first sleeve 4 outer tube walls, the screw thread of described the first sleeve 4 by its outer tube wall second sleeve 5 that has been threaded, described the second sleeve 5 is fixedly installed on described housing 1.When rotation the first sleeve 4, the first sleeve 4 rises or descends together with the second sleeve 5 with valve rod 3, simultaneously, valve rod 3 relatively rises or descends with the first sleeve 4,2 one liftings of valve rod 3 band movable valve plug, the twice that the rising or falling speed of spool 2 be the single screw driven bottom valve of tradition, so in identical switch over travel the switch bottom valve time be half of traditional single screw rod bottom valve, reduce labour intensity, improved operating efficiency.
As preferred version of the present utility model, described the first sleeve 4 tops are provided with handwheel 6.By handwheel 6 rotation the first sleeves 4, further reduced labour intensity.
As preferred version of the present utility model, described the second sleeve 5 is fixed on described housing 1 by support 7.More solid and reliable second sleeve 5 of fixing by support 7.
As preferred version of the present utility model, in described housing 1, be provided with limiting plate 8.By arrange limiting plate 8 prevent spool 2 be raised too high cause between the second sleeve 5 and the first sleeve 4 be threaded or the first sleeve 4 and valve rod 3 between be threaded and come off.
Petroleum drilling fluid solid controlling system bottom valve of the present utility model comprises housing 1 and is slidably arranged in the spool 2 in described housing 1, be provided with valve rod 3 on described spool 2, be provided with screw thread on described valve rod 3, described valve rod 3 first sleeve 4 that has been threaded, be provided with the screw thread contrary with the thread rotary orientation of described valve rod 3 on described the first sleeve 4 outer tube walls, the screw thread of described the first sleeve 4 by its outer tube wall second sleeve 5 that has been threaded, described the second sleeve 5 is fixedly installed on described housing 1, described the first sleeve 4 tops are provided with handwheel 6, described the second sleeve 5 is fixed on described housing 1 by support 7, be provided with limiting plate 8 in described housing 1.When by handwheel 6 rotation the first sleeve 4, the first sleeve 4 rises or descends together with the second sleeve 5 with valve rod 3, simultaneously, valve rod 3 relatively rises or descends with the first sleeve 4,2 one liftings of valve rod 3 band movable valve plug, the twice that the rising or falling speed of spool 2 be the single screw driven bottom valve of tradition, so in identical switch over travel the switch bottom valve time be half of traditional single screw rod bottom valve, reduce labour intensity, improved operating efficiency.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, the twice that the rising or falling speed of spool 2 is the single screw driven bottom valve of tradition, therefore in identical switch over travel, the switch bottom valve time is half of traditional single screw rod bottom valve, has reduced labour intensity, has improved operating efficiency.
