Description
Technical field
The utility model relates to a kind of drilling well igniter, the closed igniter of particularly a kind of drilling well.
Background technology
In the process of drillng operation, often there is fuel gas to be taken out of to ground by drilling fluid, common have hydrogen sulfide, a sulfur dioxide etc.These gases are often poisonous, serious threat personnel's safety and polluting the environment, so these gases are through after separating, must apply a torch burns.This just need install igniter on torch.
Igniter commonly used at present is the open type igniter, comprising: compositions such as shell, spark lever, insulator, protective cover, fire-leading cylinder, locating piece.The open type igniter is mainly used in horizontal torch, adjusts ignition gap by the relative position of regulating locating piece and spark lever.In order to save land resources, to meet the safe construction requirement of exceptional well, vertical torch is used at the scene more and more, but the open type igniter has the following disadvantages when being applied to vertical torch.
The open type igniter does not provide omnibearing protection to spark lever, insulator; when being applied to vertical torch; polluted by rainwater, dew etc. easily and destroy insulation between shell and the spark lever, can't form the condition of electrion, can not reliably working under severe weather conditions.
The locating piece of open type igniter is fixed on the spark lever by holding screw, and under the effect of gravity, ignition gap is adjusted by the relative position of regulating locating piece and spark lever in the location block is realized spark lever on insulator location.So, locating piece should play the effect of location, bears the weight of spark lever again, regulates the comparison difficulty thus.
At existing open type igniter exist to the bad weather bad adaptability, adjust the shortcoming of inconvenience, the purpose of this utility model is to propose a kind of various weather conditions, closed igniter easy to adjust of being applicable to.
Summary of the invention
For achieving the above object, a kind of drilling well that the utility model proposes comprises with closed igniter: spark lever [6], insulator [4] and fire-leading cylinder compositions such as [2].It is characterized in that having increased protection tube [5], supporting insulator [7] and ignition gap adjusting device; supporting insulator [7] is positioned between spark lever [6] and the ignition gap adjusting device; spark lever [6], insulator [4] and supporting insulator [7] are installed on protection tube [5] inside; the top of protection tube [5] is sealed; water retaining brim [1] is equipped with on the top; and have a peep hole; ignition gap adjusting device middle part is horizontally installed with fixed support [11], vertically adjusting leading screw [8] is installed, and hold-down nut [9] and locking nut [10] are installed in the both sides up and down of fixed support [11] respectively.
Owing to adopted the protection tube [5] of top closure, therefore can be under the atrocious weather condition operate as normal.Because adopted the ignition gap adjusting device of screw type, this makes that the adjustment of ignition gap is very convenient.
The purpose of this utility model, feature and advantage will be in conjunction with the embodiments, are further described with reference to accompanying drawing.
Description of drawings
Fig. 1 is a kind of drilling well with closed igniter schematic diagram.1 water retaining brim, 2 fire-leading cylinders, 3 hold-down screws, 4 insulators, 5 protection tubes, 6 spark levers, 7 supporting insulators 8 are regulated leading screw 9 hold-down nuts 10 locking nuts 11 fixed supports 12 torches
The specific embodiment
A most preferred embodiment of the present utility model now is provided in conjunction with the accompanying drawings.
As shown in the figure, protection tube [5] top closure, spark lever [6] is subjected to the support and the location of supporting insulator [7] and insulator [4].When work, keep suitable distance between spark lever [6] top and protection tube [5] top, constitute ignition gap; have peep hole symmetrically at protection tube [5] top; whether suitable, water retaining brim [1] both can stop that rainwater enters from peep hole, can not hinder observation again if can observe ignition gap.Insulator [4] is hollow, and spark lever [6] passes from the centre, and insulator [4] screw [3] that is fixed is fixed on protection tube [5] middle part, plays a part to insulate and spark lever [6] is located.The top of insulator [4] is conical; even having a small amount of drilling fluid, rainwater or dew to enter protection tube [5] also can flow down in very fast space between insulator [4] and protection tube [5]; can on insulator [4], not accumulate the insulation between breakdown point picker bar [6] and the protection tube [5].The ignition gap adjusting device comprises fixed support [11], regulates leading screw [8], hold-down nut [9] and locking nut [10].Fixed support [11] is fixed on the torch [12], and hold-down nut [9] is welded on the fixed support [11], and the position that leading screw [8] just can point of adjustment picker bar [6] is regulated in rotation, thus the adjusting ignition gap.
