Abstract
The utility model provides a side door hydraulic cylinder of a hydraulic flashboard blowout preventer, which comprises a hydraulic cylinder body, a cylinder cover, a rod piston and a locking shaft, wherein the hydraulic cylinder body is provided with a base and is cylindrical; the cylinder cover is arranged on the opening of the hydraulic cylinder body; the rod piston is arranged in the hydraulic cylinder body; the piston rod end of the rod piston passes through the center of the bottom of the hydraulic cylinder body so as to be connected with the flashboard of the blowout preventer; one end of the locking shaft passes through the center of the cylinder cover and is connected with the rod piston; and the periphery of the bottom of the hydraulic cylinder body is provided with outwards protruded flanges so as to make the bottom of the hydraulic cylinder body mutually positioned and connected with the shell of the blowout preventer. In the utility model, due to the fact that the side door in the prior art is designed into an integral structure with the hydraulic cylinder body, the piston and a piston rod, the side door hydraulic cylinder has more reasonable structure, high precision, low cost and strong safety reliability, is easy to process and is convenient to disassemble and assemble and maintain.
Description
Technical field
The utility model belongs to the petroleum machinery technical field, specifically, relates to a kind of side door hydraulic cylinder of the ram preventer that surges.
Background technology
In oil drilling and workover treatment process, for preventing the generation of blowout, well kick accident, must use preventer to seal well head, to guarantee the safety of operating personnel and equipment.The formula preventer that surges that adopt in present oil field, mainly comprise housing, side door, flashboard and hydraulic cylinder, the middle part of housing offers the main channel, the two side of housing offers the flashboard chamber symmetrically, two shoe brake plates are placed in the flashboard chamber, and side door, hydraulic cylinder and cylinder cap are equipped with outside the flashboard chamber successively in the housing both sides; Be provided with piston and piston rod in the hydraulic cylinder, an end of piston rod passes side door and links to each other with flashboard, and the other end links to each other with piston; Lock shaft passes cylinder cap and links to each other with piston; Because the hydraulic cylinder that adopted is a cylindrical shape, side door is as its cylinder bottom, and piston rod also is a minute body structure with piston, therefore, not only processed complex, precision is low, cost is high, and inconvenient dismounting and maintenance, security reliability is low.
The utility model content
For overcoming the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, side door hydraulic cylinder of being easy to process, be convenient to dismounting, the ram preventer that surges that security reliability is strong.
The technical scheme that its technical problem that solves the utility model adopts is: comprise hydraulic cylinder, cylinder cap, piston with rod and lock shaft; Described hydraulic cylinder is the band cylindrical shape at the end, and cylinder cap is loaded on the opening of hydraulic cylinder; Piston with rod places in the hydraulic cylinder, and hydraulic cylinder bottom centre is passed in the piston rod end of piston with rod, to link to each other with the flashboard of preventer; The center that one end of lock shaft passes cylinder cap links to each other with piston with rod.
The bottom periphery of above-mentioned hydraulic cylinder is provided with the flange of outside protrusion, so that be located by connecting mutually with the housing of preventer.
The beneficial effects of the utility model are: because side door of the prior art and hydraulic cylinder, piston and piston rod are designed to integrative-structure, thereby its structure is more reasonable, be easy to processing, and precision height, cost low, be convenient to dismounting and maintenance, security reliability is strong.
Description of drawings
Fig. 1 implements full structural representation for the utility model.
Among the figure: 1 is that hydraulic cylinder, 1-1 are that flange, 2 is that piston with rod, 2-1 are that piston rod, 2-2 are that wedge head, 3 is that cylinder cap, 3-1 are that pipeline, 4 is that lock shaft, 4-1 are that positive stop lug boss, 5 is that handle, 6 is that housing, 7 is that flashboard, 8 is a connecting bolt.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
The side door hydraulic cylinder of the ram preventer that surges described in the utility model comprises hydraulic cylinder 1, cylinder cap 3, piston with rod 2 and lock shaft 4; Described hydraulic cylinder 1 is the band cylindrical shape at the end, and cylinder cap 3 is loaded on the opening of hydraulic cylinder 1, and cylinder cap 3 is provided with the pipeline 3-1 that the hydraulic system with peripheral hardware interlinks; Piston with rod 2 places in the hydraulic cylinder 1, and the piston rod 2-1 end of piston with rod 2 is provided with wedge head 2-2 and passes hydraulic cylinder 1 bottom centre; The center that cylinder cap 4 is passed in the inner of lock shaft 4 and piston with rod 2 are connected by screw thread, and handle 5 is equipped with in the outer end of lock shaft 4, and locate to be provided with positive stop lug boss 4-1 being on the lock shaft 4 between piston with rod 2 and the cylinder cap 3; The bottom periphery of described hydraulic cylinder 1 is provided with the flange 2-2 of outside protrusion.
During work, two these realities of cover there are the novel both sides that are sub-packed in the housing 6 of preventer, promptly at first the wedge head 2-2 of piston rod 2-1 is connected with the flashboard 7 of preventer, the flange 1-1 with hydraulic cylinder 1 is connected with the housing 6 of preventer by connecting bolt 8 again, and pipeline 3-1 and hydraulic system interlink.When contingencies such as generation blowout or well kick, open hydraulic system, make high-pressure medium pass through pipeline 3-1 and promote the piston with rod 2 on both sides and flashboard 7 simultaneously to the main channel of housing 6 central motion, the semicircle oil pipe groove obvolvent Cheng Yuan on the flashboard 7, hold oil pipe tightly, make the well head sealing.And when outage, then the hand control handle 5, and rotational lock bar 4 is realized the sealing of well head.
Claims (2)
1. the surge side door hydraulic cylinder of ram preventer is characterized in that: comprise hydraulic cylinder, cylinder cap, piston with rod and lock shaft; Described hydraulic cylinder is the band cylindrical shape at the end, and cylinder cap is loaded on the opening of hydraulic cylinder; Piston with rod places in the hydraulic cylinder, and hydraulic cylinder bottom centre is passed in the piston rod end of piston with rod; The center that one end of lock shaft passes cylinder cap links to each other with piston with rod.
2. the side door hydraulic cylinder of the ram preventer that surges according to claim 1 is characterized in that: the bottom periphery of above-mentioned hydraulic cylinder is provided with the flange of outside protrusion.
