Description
Technical field
A kind of back-flushing filtering device of the utility model suitable for petroleum production engineering field, is specifically that a kind of water injection well is anti-
Washing and filtering device.
Background technology
Filter used by oil field water injection wellhead at present, when cleaning filter screen, it is necessary to which vent line is time-consuming, laborious,
So the replacement cycle is long, the effect of water filling filtering is influenced sometimes；A kind of water injection well backwash of the utility model design
Filtration apparatus, pipeline emptying is not required in cleaning, need to only close feed water stop valve, connects well-washing truck, opens emptying gate profit
With bottom pressure back flush filter screen, impurity screening is directly flushed in well-washing truck, i.e., convenient and safety is laborsaving, time saving
And environmental protection.
The content of the invention
In order to overcome above the deficiencies in the prior art, the utility model proposes a kind of water injection well back-flushing filtering device.
The technical scheme in the invention for solving the technical problem is：A kind of water injection well back-flushing filtering device bag
Include back with water inlet line, shell body, upper cover, filter screen, water outlet pipeline, blowdown valve body, valve body mudhole, blowdown valve valve pocket, valve pocket
Mudhole, valve inner ring blowdown space, blowdown valve valve rod, mudhole, outer jointing clip head composition；The filter screen is tiltedly placed on
In shell body, blowdown valve body ectosome is directly welded in shell body lower end, and outer jointing clip head is welded in blowdown valve body ectosome front end,
Valve body mudhole is provided with blowdown valve body, valve pocket mudhole is provided with blowdown valve valve pocket.
The beneficial effects of the utility model：The utility model proposes a kind of water injection well back-flushing filtering device, in cleaning,
Feed water stop valve need to be only closed, connects well-washing truck, emptying gate is opened and utilizes bottom pressure back flush filter screen, will filter miscellaneous
Upright connect is flushed in well-washing truck, i.e., convenient and safety, laborsaving, time saving and environmentally friendly.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
The sectional view at A-A is shown in Fig. 1 in Fig. 2.
In figure, 1- back with water inlet line, 2- shell bodies, 3- upper covers, 4- filter screens, 5- water outlets pipeline, 6- blowdowns valve body, 601-
Valve body mudhole, 7- blowdown valves valve pocket, 701- valve pockets mudhole, 8- valve inner ring blowdowns space, 9- blowdown valves valve rod, 10- blowdowns
Hole, the outer jointing clip heads of 11-.
Embodiment
The embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Fig. 1~2, a kind of water injection well back-flushing filtering device, including back with water inlet line 1, shell body 2, upper cover 3, mistake
Strainer 4, water outlet pipeline 5, blowdown valve body 6, valve body mudhole 601, blowdown valve valve pocket 7, valve pocket mudhole 701, valve inner ring row
Dirty space 8, blowdown valve valve rod 9, mudhole 10, outer jointing clip first 11 form；Described 2 one end of shell body and back with water inlet line 1
Be welded to connect, the other end is welded to connect with water outlet pipeline 5, and filter screen 4 is tiltedly placed in shell body 2,1 other end of back with water inlet line with
Shut-off valve is welded to connect, and 6 ectosome of blowdown valve body is directly welded in 2 lower end of shell body, and the welding of 6 ectosome front end of blowdown valve body is outer to be connected
Hoop 11 is connect, valve body mudhole 601 is provided with blowdown valve body 6, valve pocket mudhole 701 is provided with blowdown valve valve pocket 7.
Inject water and shell body 2 is entered by back with water inlet line 1, the injection of water outlet pipeline 5 ground is being entered by the filtering of filter screen 4
Under, backwash process is to close upper end water filling shut-off valve, and well-washing truck connects outer jointing clip first 11, opens blowdown valve valve rod 9, profit
It is with bottom pressure that impurity screening in shell body 2 is empty by the blowdown of valve inner ring by valve body mudhole 601, valve pocket mudhole 701
Between 8, mudhole 10 pour in well-washing truck, complete well-flushing function.After well-flushing, blowdown valve valve rod 9 is closed, opens upper end water filling
Shut-off valve, you can normal production.When needing replacing filter screen, water filling shut-off valve, well head production gate are closed, opens exhaust-valve
Valve rod 9 is vented the pressure in shell body 2, then opens upper cover 3 and replaces filter screen 4.
During installing and using, feed water stop valve need to be only closed, connects well-washing truck, emptying gate valve bar 9 is opened and utilizes shaft bottom
Pressure reversal washing filter screen, impurity screening is directly flushed in well-washing truck, i.e., convenient and safe, laborsaving, time saving and ring
Protect.
