Abstract
The utility model relates to the antitheft choke valve of a kind of water injection well in oil exploitation water injection well field.Technical scheme: comprise the screw mandrel in valve body, valve body, the flashboard of screw mandrel lower end and valve body delivery port, it is characterized in that: at the outer sheathed large lid of valve body top screw mandrel, cover greatly the sheathed copper sheathing of end, copper sheathing upper end adds rotary body, and rotary body outer wall arranges multiple axial bond, and rotary body upper end is installed with pressure cap, rotary body inwall and screw mandrel screwed connection, at large hd top face welding shield, guard shield top extends above the top of screw mandrel, and key and the bottom keyway taking spanner outward of rotary body outer wall plug rear rotatable engagement.Beneficial effect: this technology rotary body replaces the handwheel on former valve, structure is simple, and volume is little, saves raw material, and rotary body outer wall arranges multiple axial bond and takes spanner outward and coordinate, and guard shield is equipped with again in outside, and common wrench cannot use, good anti-theft effect.
Description
Technical field
The utility model relates to the antitheft choke valve of a kind of water injection well in oil exploitation water injection well field.
Background technology
On-the-spot water injection well valve is generally 250 model high pressure valve, it deposits drawback both ways: 1, gate accessory handwheel, copper sheathing etc. are easily stolen, cause switch gate inconvenient, impact management, can be there is destroyed molecule closedown water filling gate aborning in water injection well on the other hand, cause water injection well voltage rise high, well cannot normally water filling, affects oil well and normally produces; 2, injection pressure is very high, and gate usually occurs that ram seal face thorn is bad in use for some time, the situation such as to fit badly, and frequent switch, easily occur sealing part leakage, need to change, increase cost, workload strengthens.
Utility model content
The purpose of this utility model is for above-mentioned technical deficiency, have studied the antitheft choke valve of water injection well that a kind of antitheft, corrosion-resistant impact resistance is strong.
Technical scheme: comprise the screw mandrel in valve body, valve body, the flashboard of screw mandrel lower end and valve body delivery port, it is characterized in that: at the outer sheathed large lid of valve body top screw mandrel, cover greatly the sheathed copper sheathing of end, copper sheathing upper end adds rotary body, and rotary body outer wall arranges multiple axial bond, and rotary body upper end is installed with pressure cap, rotary body inwall and screw mandrel screwed connection, at large hd top face welding shield, guard shield top extends above the top of screw mandrel, and key and the bottom keyway taking spanner outward of rotary body outer wall plug rear rotatable engagement.
Angle is had to arrange between multiple axial bond that described rotary body outer wall is arranged and rotary body axis.
Described valve body delivery port inwall is threaded connection faucet.
Beneficial effect: this technology rotary body replaces the handwheel on former valve, structure is simple, and volume is little, saves raw material, and rotary body outer wall arranges multiple axial bond and takes spanner outward and coordinate, and guard shield is equipped with again in outside, and common wrench cannot use, good anti-theft effect.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present embodiment.
Detailed description of the invention
With reference to accompanying drawing 1, the present embodiment mainly comprises screw mandrel 3 in valve body 1, valve body 1, the flashboard 4 of screw mandrel 3 lower end and valve body delivery port 2, at the outer sheathed large lid 5 of valve body 1 top screw mandrel, the sheathed copper sheathing 6 in large lid 5 upper end, copper sheathing 6 upper end adds rotary body 7, rotary body 7 outer wall arranges multiple axial bond 8, rotary body 7 upper end is installed with pressure cap 9, rotary body 7 inwall and screw mandrel 3 screwed connection, at large lid 5 end face welding shields 11, guard shield 11 top extends above the top of screw mandrel 3, and key 8 and the bottom keyway taking spanner 10 outward of rotary body 7 outer wall plug rear rotatable engagement; Multiple axial bonds 8 that described rotary body 7 outer wall is arranged with have into 60 degree of angles between rotary body 7 axis and arrange; Described valve body delivery port 2 inwall is threaded connection faucet, the shock proof alloy material water nozzle of faucet anticorrosion, for regulating water injection rate, avoiding and causing lock to pull the bad drawback of thorn with gate adjustment, providing cost savings.
Operating principle illustrates: after being installed by gate clip, different-diameter water nozzle is selected according to different injection amount, load gate, all gate is opened during water filling, because the space before water nozzle is large, water nozzle aperture is little, reach throttling object, the note speed before water nozzle is lower, is increased by flow velocity during water nozzle, the impact force acted on like this on flashboard is just transferred on water nozzle, avoid flashboard perverse bad, if perverse bad after water nozzle Long-Time Service, water nozzle can be changed by screw thread, ensure that the sealing of gate, and save maintenance cost.
Claims (3)
1. the antitheft choke valve of water injection well, comprise the screw mandrel in valve body, valve body, the flashboard of screw mandrel lower end and valve body delivery port, it is characterized in that: at the outer sheathed large lid of valve body top screw mandrel, cover greatly the sheathed copper sheathing of end, copper sheathing upper end adds rotary body, rotary body outer wall arranges multiple axial bond, rotary body upper end is installed with pressure cap, rotary body inwall and screw mandrel screwed connection, at large hd top face welding shield, guard shield top extends above the top of screw mandrel, and key and the bottom keyway taking spanner outward of rotary body outer wall plug rear rotatable engagement.
2. the antitheft choke valve of water injection well according to claim 1, is characterized in that: have angle to arrange between multiple axial bond that described rotary body outer wall is arranged and rotary body axis.
