Abstract
Disclosed is a closer for an oil field wellhead valve. The closer for the oil field wellhead valve mainly solves the problem the oil field wellhead valve is difficult to operate by oil extraction workers, hard to rotate and incapable of being opened or closed at critical moments. The closer is characterized in that two jack catches (2) are horizontally and fixedly connected at the left end of a hinge rod (1), and the two jack catches (2) are spaced at a certain distance; the bottom of the middle portion of the hinge rod (1) is provided with a semicircular centering block (4); a force exerting pipe (3) is arranged at the right end of the hinge rod (1) and connected with the hinge rod (1) through a pin hole and a pin roll; the right end of the force exerting pipe (3) is horizontally connected with a rocker handle (5). The closer for the oil field wellhead valve has the advantages of opening and closing the valve conveniently and easily and being capable of thoroughly opening or tightly closing the valve.
Description
Technical field:
The utility model relates to oil field shaft mouth instrument used, the derailing switch that especially oil field shaft mouth valve is used.
Background technology:
In oil extraction in oil field field, oil recovery work is mainly responsible for the work such as well head and the adjustment of metering room well liquid.The adjustment of well liquid just needs continuous controlled valve, and due to the larger oil recovery work of oil field shaft mouth valve operating difficulties, rotates motionlessly, wastes time and energy, and does not open crucial moment or close not deadly, affects oil recovery efficiency.
Utility model content:
In order to solve oil field shaft mouth valve oil recovery work operating difficulties, rotate motionlessly, waste time and energy, and do not open crucial moment or close not dead problem.The derailing switch that the utility model provides a kind of oil field shaft mouth valve to use.It is convenient easily that the derailing switch that this oil field shaft mouth valve is used has controlled valve, beats to such an extent that open or close extremely feature.
The technical solution of the utility model is: the derailing switch that this oil field shaft mouth valve is used comprises toggle, claw and boosting pipe.Two claws are laterally fixedly connected on toggle left end, between two claws, have distance, and in toggle, subordinate has semicircle center bridge, and boosting pipe is placed in toggle right-hand member, and are connected with bearing pin by pin-and-hole, and boosting pipe right-hand member is horizontally connected with crank.
The utlity model has following beneficial effect: derailing switch two claws that this oil field shaft mouth valve is used are laterally fixedly connected on toggle left end, between two claws, there is distance, semicircle bluff piece is longitudinally fixedly connected on two claw outer ends, in toggle, subordinate has semicircle center bridge, boosting pipe is placed in the another right-hand member of toggle, and be connected with bearing pin by pin-and-hole, boosting pipe right-hand member is horizontally connected with crank structure.Utilize toggle, claw and boosting pipe to increase valve handle radius, according to lever principle, make valve handle rotation easily, oil recovery work processing ease, time saving and energy saving, beat crucial moment to such an extent that open or close extremely, and also simple in structure, low cost of manufacture.It is convenient easily that the derailing switch that this oil field shaft mouth valve is used thus has controlled valve, beats to such an extent that open or close extremely feature.
Accompanying drawing explanation:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is Fig. 1 top views.
1-toggle in figure, 2-claw, 3-boosting pipe, 4-center bridge, 5-crank.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in drawings, the derailing switch that this oil field shaft mouth valve is used comprises toggle 1, claw 2 and boosting pipe 3.Two claws 2 are laterally fixedly connected on toggle 1 left end, between two claws 2, have distance, and distance is slightly larger than head valve handwheel wheel rim width, are conveniently connected with the wheel rim of head valve handwheel.In toggle 1, subordinate has semicircle center bridge 4, center bridge 4 is sitting on the screw mandrel of head valve, and center bridge 4 plays a part to stablize the derailing switch that this oil field shaft mouth valve is used, and makes safer.Boosting pipe 3 is placed in toggle 1 right-hand member, and be connected with bearing pin by pin-and-hole, boosting pipe 3 right-hand members are horizontally connected with crank 5, according to lever principle, the derailing switch toggle 1 that this oil field shaft mouth valve is used is connected longer switch oil field head valve with boosting pipe 3 more laborsaving, when normal switch oil field shaft mouth valve, utilize crank 5 rotations easily convenient.
Operating principle:
First according to the size of head valve, adjust boosting pipe 3 length, head valve just elongates boosting pipe 3 to the right greatly, head valve is little just to be shortened boosting pipe 3 left, derailing switch two claws 2 of again this oil field shaft mouth valve being used are enclosed within on the wheel rim of head valve handwheel, again center bridge 4 is sitting on the screw mandrel of head valve, gets final product light switch oil field head valve, and beat to such an extent that switch obtains extremely, time saving and energy saving, convenient and swift.
Claims (1)
1. the derailing switch that oil field shaft mouth valve is used, comprise toggle (1), claw (2) and boosting pipe (3), it is characterized in that: two claws (2) are laterally fixedly connected on toggle (1) left end, two claws have distance between (2), in toggle (1), subordinate has semicircle center bridge (4), boosting pipe (3) is placed in toggle (1) right-hand member, and is connected with bearing pin by pin-and-hole, and boosting pipe (3) right-hand member is horizontally connected with crank (5).
