Abstract
The invention relates to a petroleum drilling fluid solid control system device and particularly relates to a petroleum drilling fluid solid control system bottom valve. The bottom valve comprises a casing (1) and a valve element (2) which is arranged in the casing (1) in a sliding mode, a valve rod (3) is arranged on the valve element (2) and provided with a thread, and the valve rod (3) is in threaded connection with a first sleeve (4). The bottom valve is characterized in that a thread is arranged on the outer sleeve wall of the first sleeve (4), a helix direction of the thread is opposite to that of the thread of the valve rod (3), the first sleeve (4) is in threaded connection with a second sleeve (5) through the thread on the outer sleeve wall of the first sleeve (4), and the second sleeve (5) is fixedly arranged on the casing (1). According to the petroleum drilling fluid solid control system device, the lifting speed of the valve element (2) is two times that of a traditional single screw driven bottom valve, so that under the same switching path, the time for opening and closing the bottom valve is half of that for opening and closing the traditional single screw driven bottom valve, labor intensity is reduced, and work efficiency is improved.
Description
Technical field
The present invention 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 drillng operation circulation of drilling fluid, bottom valve is the gauge tap of the suction line of 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 to adopt 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.In the time adopting 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, affect greatly the efficiency of drillng operation, while especially processing underground emergency accident, because bottom valve switch motion is slow, easily cause security incident; In addition, this fine pitch list screw drive, because pitch is little, when handwheel rotates a circle, less height can only be mentioned or reduce to spool, so it is large to operate labour intensity in the time of 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.
Summary of the invention
Goal of the invention of the present invention is: the switch motion existing for existing petroleum drilling fluid solid controlling system bottom valve slowly and the large problem of operation 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 used in the present invention 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, on described spool 2, be provided with valve rod 3, on described valve rod 3, be provided with screw thread, described valve rod 3 first sleeve 4 that has been threaded, on described the first sleeve 4 outer tube walls, be provided with the screw thread contrary with the thread rotary orientation of described valve rod 3, described the first sleeve 4 is by the screw thread of its outer tube wall second sleeve 5 that has been threaded, and described the second sleeve 5 is fixedly installed on described housing 1.In the time of rotation the first sleeve 4, the first sleeve 4 rises or declines together with the second sleeve 5 with valve rod 3, simultaneously, valve rod 3 relatively rises or declines with the first sleeve 4, valve rod 3 is with movable valve plug 2 one liftings, and the rising or falling speed of spool 2 is the twice of the single screw driven bottom valve of tradition, and therefore in identical switch over travel, the switch bottom valve time is the half of traditional single screw rod bottom valve, reduce labour intensity, improved operating efficiency.
As preferred version of the present invention, described the first sleeve 4 tops are provided with handwheel 6.Rotate the first sleeve 4 by handwheel 6, further reduced labour intensity.
As preferred version of the present invention, described the second sleeve 5 is fixed on described housing 1 by support 7.By support 7 more solid and reliable fix the second sleeve 5.
As preferred version of the present invention, 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 invention comprises housing 1 and is slidably arranged in the spool 2 in described housing 1, on described spool 2, be provided with valve rod 3, on described valve rod 3, be provided with screw thread, described valve rod 3 first sleeve 4 that has been threaded, on described the first sleeve 4 outer tube walls, be provided with the screw thread contrary with the thread rotary orientation of described valve rod 3, described the first sleeve 4 is by the screw thread of 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, in described housing 1, be provided with limiting plate 8.In the time rotating the first sleeve 4 by handwheel 6, the first sleeve 4 rises or declines together with the second sleeve 5 with valve rod 3, simultaneously, valve rod 3 relatively rises or declines with the first sleeve 4, valve rod 3 is with movable valve plug 2 one liftings, and the rising or falling speed of spool 2 is the twice of the single screw driven bottom valve of tradition, and therefore in identical switch over travel, the switch bottom valve time is the half of traditional single screw rod bottom valve, reduce labour intensity, improved operating efficiency.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows:
1, the rising or falling speed of spool 2 is the twice of the single screw driven bottom valve of tradition, and therefore in identical switch over travel, the switch bottom valve time is the half of traditional single screw rod bottom valve, has reduced labour intensity, has improved operating efficiency.
