Description

The side door preventer that band air damping buffer solution compresses switch
Technical field
The utility model relates to ram preventer, is specifically related to a kind of side door preventer that compresses switch with the air damping buffer solution.
Background technology
At present, in the natural petroleum gas field process, ram preventer is one of indispensable safety means in the drilling process, usually need change the flashboard in different apertures according to different drilling rods, sleeve pipe, oil pipe.The installation of side door is opened and is taked hydraulic way, in opening the side door process, in the open and close small oil tank annular space on the side door hydraulic oil is arranged all; In pressure process, open and close small oil tank annular space all receives hydraulic coupling, and opening process speed is fast, and is not steady, has potential safety hazard.Open side door fast, cause the mutual collision between small oil tank bar, the change-over panel etc. easily, cause the damage of component, increase operating cost.
Summary of the invention
The purpose of the utility model is: a kind of side door preventer that compresses switch with the air damping buffer solution is provided, and this hydraulic selector is opened slowly, steadily side door, guarantees that small oil tank bar, change-over panel do not have impact, guarantees operating personnel's life safety.
The technical solution that the utility model adopts is: this hydraulic selector comprises housing, cuts out the small oil tank bar, change-over panel, side door, close small oil tank, open small oil tank, piston rod, side door oil cylinder and open the small oil tank bar; Change-over panel is between housing and side door; Change-over panel is connected fixedly on the side door by soket head cap screw, closes small oil tank and is placed on respectively in the small oil tank installing hole of side door with the unlatching small oil tank, closes small oil tank bar one end and is connected in the housing; The other end of closing the small oil tank bar passes change-over panel and is connected and closes in the small oil tank; Piston on the piston rod is installed in and forms hydraulic cylinder in the side door oil cylinder, and piston rod connects flashboard, opens small oil tank bar one end and is connected in the housing; The unlatching small oil tank bar other end passes change-over panel and is connected in the unlatching small oil tank, whole formation hydraulic selector; Wherein, close the small oil tank bar, close that small oil tank, side door are closed the small oil tank hole and hydraulic cylinder forms the side door open oil channel; Wherein, open small oil tank, unlatching small oil tank bar and side door and open small oil tank hole formation air damping.
In the side door opening process, be full of hydraulic oil in the side door open oil channel, hydraulic coupling promotes side door and moves right together with change-over panel, opens side door; Open small oil tank, open the obstructed hydraulic oil of annular space of small oil tank bar and the hole formation of side door unlatching small oil tank, along with the unlatching of side door, annular volume increases, and forms vacuum, generates negative pressure, slows down the speed that side door is opened.
The utility model is simple in structure, and is easy to operate, and the side door opening speed is steady, prevents that component such as small oil tank bar, change-over panel and small oil tank from bumping, and avoids damage of components, guarantees operating personnel's life safety.
Description of drawings
Fig. 1 opens back structure sectional view for the utility model side door.
Fig. 2 opens the pre-structure sectional view for the utility model side door.
Among the figure: 1 housing, 2 close the small oil tank bar, 3 change-over panels, 4 side doors, 5 close small oil tank, and 6 open small oil tank, 7 piston rods, 8 side door oil cylinders, 9 open the small oil tank bar.
The specific embodiment
Like Fig. 1, shown in 2; This hydraulic selector comprises housing 1, cuts out small oil tank bar 2, change-over panel 3, side door 4, close small oil tank 5, open small oil tank 6, piston rod 7, side door oil cylinder 8 and open small oil tank bar 9, change-over panel 3 is between housing 1 and side door 4, change-over panel 3 is by the soket head cap screw connection fixedly on the side door 4; Closing small oil tank 5 is placed on respectively in the small oil tank installing hole of side door 4 with unlatching small oil tank 6; Close small oil tank bar 2 one ends and be connected in the housing 1, the other end of closing small oil tank bar 2 passes change-over panel 3 and is connected and closes in the small oil tank 5, and the piston on the piston rod 7 is installed in and forms hydraulic cylinders in the side door oil cylinder 8; Piston rod 7 connects flashboard; Open small oil tank bar 9 one ends and be connected in the housing 1, unlatching small oil tank bar 9 other ends pass change-over panel 3 and are connected in the unlatching small oil tank 6, whole formation hydraulic selector; Wherein, close small oil tank bar 2, close that small oil tank 5, side door are closed the small oil tank hole and hydraulic cylinder forms the side door open oil channel; Wherein, open small oil tank 6, unlatching small oil tank bar 9 and side door unlatching small oil tank hole formation air damping.
After flashboard cuts out, be full of hydraulic oil in the oil circuit of before side door is opened, close small oil tank bar 2, close small oil tank 5, side door being closed the small oil tank hole and hydraulic cylinder forms; Open no hydraulic oil in the annular space of small oil tank hole formation and open small oil tank 6, unlatching small oil tank bar 9 and side door, have only a spot of air; Increase along with pressure; Side door 4 is opened, and in the process that side door 4 is opened, the annular volume of opening small oil tank 6, unlatching small oil tank bar 9 and the hole formation of side door unlatching small oil tank increases gradually; A spot of air is pumped into vacuum; Form negative pressure, thereby hinder the unlatching of side door 4, slow down the opening speed of side door 4.
