Description
Technical field
The utility model belongs to oil field pipeline cleaning plant, particularly relates to a kind of oil field single tube block clearing device.
Background technology
The oil field is in the crude oil gatherer process, because undressed crude oil contains various impurity, on the tube wall of these impurity attached to crude oil pipeline, in the course of time, will cause the pipeline circulation area of conveying crude oil constantly to reduce even blocks fully.At this situation, oilfield operations worker will periodically clear up pipeline, and the main at present mode that adopts has modes such as receiving ball tube and pipe cleaning valve to carry out pigging, but these methods all can't reach desirable effect.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of oil field single tube block clearing device is provided.
Single tube block clearing device in oil field of the present utility model, be to connect ball collecting device by ball injector by pipeline to constitute, described ball injector is to be provided with hollow valve ball in the pitching valve body, the top of pitching valve body connects the pitching tube corresponding to the position of hollow valve ball, storage block clearing ball in the pitching tube, shelve counter weight on the block clearing ball, pitching tube suitable for reading has the shutoff nut; Sidewall at the pitching valve body is provided with driving machine, and driving machine is built-in with the PLC controller, and the output shaft of driving machine is connected with the valve rod same axis of hollow valve ball.
As further improvement of the utility model, on the pitching tube, be provided with vent valve, the blowdown bolt arranged in pitching valve body bottom.
As further improvement of the utility model, described ball collecting device is to be provided with hollow valve ball in receiving ball valve body, valve rod and the hollow valve ball received on the ball valve body sidewall are fixedly connected, and the bottom of receiving ball valve body is communicated with ball collecting chamber, the sidewall of ball collecting chamber be provided be with blind plate get the player hole.
Single tube block clearing device in oil field of the present utility model, reasonable in design belongs to the electronic automatic ball-throwing equipment of normal pressure, has realized the automatic ball-throwing of automatics, and the interior crude oil medium of pipeline can not enter in the pitching tube during pitching, and continuing to flow in the pitching process does not build the pressure; Good blocking cleaning effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1 ball injector;
Fig. 3 is the side view of Fig. 1 ball collecting device.
The specific embodiment
Single tube block clearing device in oil field of the present utility model is to connect ball collecting device 3 by ball injector 1 by pipeline 2 to constitute.
Described ball injector 1 is to be provided with hollow valve ball 5 in pitching valve body 4, the top of pitching valve body 4 connects pitching tube 6 corresponding to the position of hollow valve ball 5, storage block clearing ball 7 in the pitching tube 6, shelve counter weight 8 on block clearing ball 7, pitching tube 6 suitable for reading has shutoff nut 9; Sidewall at pitching valve body 4 is provided with driving machine 10, and the output shaft of driving machine 10 is connected with valve rod 11 same axis of hollow valve ball 5.
Driving machine is provided with the PLC controller, when reaching pitching during the time, PLC control electric device is closed the ball core, this moment, medium was continued to flow by the defeated downstream of the built-in channel of ball core, when PLC monitor the ball core close put in place and reach delay time after, control electric device again the ball core is opened, spherical pig is finished automatic ball-throwing once with the pitching valve core rotation to feed-line.
Need
ManuallyWhen adding ball, open vent valve, when confirming that the pitching bucket does not have pressure, open the pitching bung, add spherical pig, screw in the pitching bung, and get final product with display setting spheroid number.
Ball injector employing front and back bar dual-gripper, band preloading spring two way seal mode has sealing reliably, advantages such as keying is rapid, long service life; Ball-throwing apparatus has electrostatic-proof function, can not produce electrostatic spark because of soft seal macromolecular material and metal friction, and this has great benefit to the safety that guarantees petroleum pipeline; In the pitching process, install built-in bypass line and guaranteed that pipeline can not build the pressure.
On pitching tube 6, be provided with vent valve 18, blowdown bolt 19 arranged in pitching valve body 4 bottoms.
Described ball collecting device 3 is to be provided with hollow valve ball 13 in receiving ball valve body 12, the valve rod of receiving on ball valve body 12 sidewalls 14 is fixedly connected with hollow valve ball 13, the bottom of receiving ball valve body 12 is communicated with ball collecting chamber 15, and what the sidewall of ball collecting chamber 15 was provided with band blind plate 16 gets player hole 17.
Ball collecting device is designed to tubular, and during operate as normal, the block clearing ball drops automatically in bucket, and crude oil enters downstream line by receiving system; When needs were collected the block clearing ball, by the conversion of conversion equipment, receiving system and petroleum pipeline were isolated, and crude oil enters the downstream from bypass line, need not cut off sprue and can directly take out spherical pig.
