And a kind of water injection well stable current regulator is provided.The water injection well stable current regulator, it is corrosion-resistant high pressure resistant, reduce water attack, operation letter
It is single, adjust water injection rate accurate.
The present invention solves its problem can be reached by following technical solution：The water injection well stable current regulator, including main body,
Connection high-pressure water pipe in the horizontal through hole of the main body lower end, main center's inner chamber is connected to valve pocket, valve pocket built with valve cylinder, on valve cylinder
Seat has water regulating valve, and water regulating valve connection runoff investigation bar, runoff investigation bar emits connection torque arm by lock.
The valve cylinder and water regulating valve prepare the component and proportioning of material：Titanate fiber 15%, ceramics
Powder 18%, high-carbon comminuted steel shot 55%, high molecular weight ptfe 5%, resin 7%.
Wherein titanate fiber has strengthens tensile strength, toughness, corrosion resistant effect, and ceramic powder has wear-resisting, corrosion resistant
Erosion, the effect for increasing hardness；High-carbon comminuted steel shot can strengthen intensity；High molecular weight ptfe is wear-resisting；Resin is used as above-mentioned material
Compound synthetics.
The water regulating valve 5 plays three kinds of effects and 1. precisely finely tunes the water yield；2. the discharge capacity of water injection well well-flushing water is controlled；3. when
When valve cylinder 6 and water regulating valve 5 are closed, closing structure adopts conical surface linear sealing, is not impacted by the water yield at ordinary times, it is ensured that sealing effect
Really.
It is of the invention to have the advantages that compared with above-mentioned background technology：The water injection well stable current regulator, one
Runoff investigation valve rod plays three kinds of operation effects, simple to operate, corrosion-resistant high pressure resistant, reduces water attack, and water injection rate precisely, reduces maintenance
Workload, reduces cost.
