Technical solution adopted in the utility model is: a kind of combustion in situ electric ignition Long-distance Control preventer device, formed by seal assembly, standby assembly and blowout prevention assembly; Seal assembly comprises pressure cap, cylinder body flange, packing unit and piston, pressure cap is connected with cylinder body flange upper end, cylinder body flange inner chamber is equipped with wiper block, packing unit, following wiper block and piston from top to bottom, and armored cable passes in the middle of last wiper block, packing unit, following wiper block and piston; Standby assembly by square cylinder body, partly seal integrated, clamping is integrated and blind flange is formed, standby assembly top is connected with the cylinder body flange bolt and seals by steel ring, standby assembly bottom is connected with the clip flange bolt and seals by steel ring, partly seal the integrated square cylinder body top that is positioned at, bilateral symmetry is provided with double packing of cylinder, push-pull screw, piston rod and seal combination in square cylinder body, clamping is integrated to be positioned at square inferior part of the cylinder block, and bilateral symmetry is provided with cylinder and half-and-half blocks tooth, push-pull screw, piston rod and seal combination in square cylinder body; The blowout prevention assembly is made up of a cover flap formula safety valve and clip flange, and flap formula safety valve is made up of valve plate seat, pivot pin, torsion spring and valve plate, and pivot pin passes from the clip flange inner wall.
Packing unit and partly seal double packing of integrated cylinder and adopt fluorubber to make.
The beneficial effects of the utility model are: the utility model has been owing to adopted standby assembly, thereby has the advantage of changing sealing component safe ready, can the positiver sealing armored cable; Owing to adopted the blowout prevention assembly, thereby can guarantee that armored cable trips out or disconnected moment of taking off is played automatic blowout prevention effect.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of combustion in situ electric ignition Long-distance Control preventer device is made up of seal assembly 3, standby assembly 2 and blowout prevention assembly 1; Seal assembly 3 comprises pressure cap 5, cylinder body flange 6, packing unit 7 and piston 8, pressure cap 5 is connected with cylinder body flange 6 upper ends, 2 hydraulic pressure hole connectors are arranged on cylinder body flange 6 housings, cylinder body flange 6 inner chambers are equipped with wiper block, packing unit 7, following wiper block and piston 8 from top to bottom, and armored cable 4 passes in the middle of last wiper block, packing unit 7, following wiper block and piston 8; Piston 8 forms hydraulic cavities with cylinder body flange 6 inner chambers, this hydraulic cavities is communicated with 2 hydraulic pressure holes on cylinder body flange 6 housings, the hydraulic pressure hole connector links to each other with the long-range hydraulic system of outside up and down, when the hydraulic oil supercharging is advanced in the hydraulic pressure hole instantly, the hole discharge opeing of last hydraulic pressure, form pressure reduction, it is up to promote piston 8 during the hydraulic oil supercharging, compression seal glue core 7, packing unit 7 hugs armored cable 4, forms contact closely with it, isolates the pressure between pit shaft inside and the atmosphere, thereby realize sealing, sealing effectiveness depends on and applies the pressure of operator's control on the blowout prevention box.The minimum hydraulic pressure that is applied on the blowout prevention box is in order to prevent that air from leaking.Remaining pressure is compression elastic element then, causes flexible member that deformation takes place rapidly, and the minimum axial direction load that armored cable 4 moves is kept in increase in seal assembly 3; Standby assembly 2 is by square cylinder body 9, partly seal integrated 10, clamping integrated 12 and blind flange 11 are formed, standby assembly 2 tops are connected with cylinder body flange 6 bolts and seal by steel ring, standby assembly 2 bottoms are connected with clip flange 14 bolts and seal by steel ring, partly seal integrated 10 and be positioned at square cylinder body 9 tops, bilateral symmetry is provided with double packing of cylinder in square cylinder body 9, push-pull screw, piston rod and seal combination, its effect is when needing to change the packing unit 7 of seal assembly 3, the hydraulic pressure hole connector that partly seals integrated 10 correspondences is linked to each other with the long-range hydraulic system of outside, hydraulic oil from long-range hydraulic system acts on the piston rod, piston drives push-pull screw and moves to center armored cable 4 directions, make double packing of cylinder tightly embrace armored cable 4, play sealing function, unload pressure cap 5 this moment, and pressurizeing by the long-range hydraulic system of outside ejects the packing units 7 in the seal assembly 3 namely replaceable; Clamping integrated 12 is positioned at square cylinder body 9 bottoms, bilateral symmetry is provided with cylinder and half-and-half blocks tooth, push-pull screw, piston rod and seal combination in square cylinder body 9, its effect is to block armored cable 4, prevent that it from moving up and down, play the suspension effect, it is identical that integrated 10 methods are partly sealed in its hydraulic operation method and operation; Blowout prevention assembly 1 is made up of a cover flap formula safety valve 13 and clip flange 14, flap formula safety valve 13 is by the valve plate seat, pivot pin, torsion spring and valve plate are formed, pivot pin passes from clip flange 14 inwalls, valve plate is that axle opens closure up and down with the valve plate seat with the pivot pin, seal with the valve plate seat when closed, opening needs armored cable 4 to back down valve plate, be in open mode, within it the time, valve plate does not reset under spring action armored cable 4, and valve plate is in closed condition, its effect is that flap is closed automatically when proposing armored cable 4, prevent the generation of blowout, can close well head by automatic emergency in the time of in the unexpected disconnected well that comes off of cable, prevent that unexpected blowout from taking place.Clip flange 14 bottom shapes can require to be made into buckle-like or flange-like is supporting with it according to wellhead assembly, packing unit 7 and partly seal double packing of integrated 10 cylinder and adopt fluorubber to make, the cylinder of clamping integrated 12 half-and-half blocks tooth and adopts stainless steel 1Cr18Ni9Ti material Quenching Treatment.
Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
