Description
The utility model relates to ball valve and the moushroom valve connecting pipe type oil well pump that a kind of oil field machinery oil is used.
In the prior art, the oil field machinery oil pump that is used for petroleum production generally adopts three valve tubing pumps, and its structure comprises working barrel, working barrel liner steel bushing, and they constitute pumping pipelines.The piston that moves about that is complementary with the steel bushing internal diameter is arranged in the pipeline, and the piston top side that moves about has oil outlet, and oil outlet and pumping pipelines communicate.Move about piston head and sucker rod joins.The lift on sucker rod and ground links to each other.Moving about has upper and lower two steel balls in the piston, and respectively there is the ring-type ball seat two steel balls belows.Move about the below of piston by the valve of being made up of the steel ball of ring-type ball seat and ball seat top, above the steel ball fixed disc is arranged, oil through is arranged on the disk.When the oil suction of oil well pump piston down stroke, crude oil adds the flowing pressure of rod weight greater than crude oil in the oil reservoir in the pipeline, and the steel ball of fixed disc below is located on thereunder the ring-type ball seat by the surface pressure effect, and following valve is closed.The former oil pressure that moves about between piston and the following valve rises, and upwards backs down two steel balls of two ring-type ball seat tops in the piston that moves about, and crude oil upwards pours in the pumping pipelines.When moving about the piston upstroke, moving about, two steel balls are located on the annular ball seat downwards respectively in the piston, the piston that moves about is closed, shape local space between piston and the following valve moves about, pressure is less than the pressure of in-place oil between them, in-place oil backs down down the steel ball on the valve retaining ring shape ball seat, and following valve is opened, and in-place oil enters in the pump.So continuous working in reciprocating mode forms oil pumping process.
The following valve of three valve formula oil well pumps is single ball sealing, causes crude oil leakage easily.Generally speaking, in two steel balls in the piston that moves about, last ball seals, and following ball is inoperative.Have only when last ball seal leakage is big, following ball just seals, so in fact, still single ball sealing in the piston that moves about, sealability is relatively poor, easily causes crude oil leakage, so pump efficiency is not high.
The purpose of this utility model provides a kind of good seal performance, the pumping efficiency height, in the upper and lower piston ball valve and plate valve at work bivalve with open and bivalve with the ball valve and the moushroom valve connecting pipe type oil well pump that close.
The utility model is to realize like this, ball valve that this oil field machinery oil is used and moushroom valve connecting pipe type oil well pump comprise working barrel, working barrel liner steel bushing, constitute pumping pipelines, the piston that moves about that is complementary with the steel bushing internal diameter is arranged in the pipeline, the piston top side that moves about has oil outlet, move about piston head and sucker rod joins, sucker rod links to each other with the ground rise or fall machine, be characterized in: the cylindrical valve cover of going up is arranged at the piston top of moving about, on the last disk of last valve cover oil through is arranged, oil through communicates with the pumping pipelines on the piston top of moving about, in the inner chamber of last valve cover steel ball is arranged, on the lower disc of last valve cover circular hole is arranged, be embedded with in the circular hole and can go up, mobile down cylindrical small piston, circular oil pipe is arranged in the middle of the small piston, the small piston top end is a ball valve seat, there is the cylindrical limited step of projection at the small piston middle part, the other oil inlet hole that has in the small piston cylinder side of limited step below, it communicates with oil pipe, the small piston below is a plate valve, its below is the ring-type lower valve base, the fixed piston that is fixed on the pumping pipelines tube wall is being arranged below the piston that moves about, the structure of fixed piston is similar with the above-mentioned structure of piston of moving about, its composition comprises the valve cover, on the last disk of last valve cover oil through is arranged, its pumping pipelines with last valve cover top communicates, in the inner chamber of last valve cover steel ball is arranged, on the lower disc of last valve cover circular hole is arranged, be embedded with cylindrical small piston moving up and down in the circular hole, circular oil pipe is arranged in the middle of the small piston, the small piston top end is a ball valve seat, there is the cylindrical limited step of projection at the small piston middle part, the other oil inlet hole that has in the small piston cylinder side of limited step below, it communicates with oil pipe, the below of small piston is a plate valve, its below is the ring-type lower valve base, and lower valve base and valve bonnet are as a whole, valve seat below union tail.Its working principle is: when moving about during the oil suction of piston down stroke of ball valve and moushroom valve connecting pipe type oil well pump, the piston that moves about moves down, crude oil adds the flowing pressure of rod weight greater than crude oil in the oil reservoir in the pipeline, and the upper steel ball seat in the fixed piston is enclosed on the ball valve seat of small piston oil pipe outlet.Simultaneously, small piston is descending, makes small piston bottom plate-like valve seat seal ring shape lower valve base, and two valves cut out simultaneously in the fixed piston.At this moment the former oil pressure that moves about between piston and the fixed piston rises, back down the plate valve on the annular lower valve base of the piston that moves about, small piston moves up, because limited step is stuck in valve cover lower end surface, small piston stops to move, crude oil backs down steel ball on the mouth of pipe ball valve seat through the small piston oil pipe, and two valves are opened simultaneously in the piston that moves about, and the oil outlet of crude oil on last valve cover pours in the pumping pipelines.Otherwise, when oil well pump moved about the piston upstroke, the last steel ball in the piston that moves about was enclosed in the outlet of small piston oil pipe by the interior former oil pressure effect seat of oil pipe, and small piston is descending, small piston bottom plate-like valve seat is encapsulated on the ring-type lower valve base, and two valves cut out simultaneously in the piston that moves about.Move about and form the space between piston and the fixed piston, pressure between them is less than in-place oil pressure, the formation oil tail pipe of flowing through backs down plate valve on the fixed piston annular lower valve base, make on the small piston of fixed piston and move, limited step is stuck in valve cover lower end surface, and oil stream backs down the top steel ball from the small piston import through the small piston oil pipe, and two valves of fixed piston are opened simultaneously, in-place oil enters in the pump, fills up the space of moving about between piston and the fixed piston.Like this, constantly working in reciprocating mode forms oil pumping process.Two valves are two in two valves in the piston and the fixed piston owing to move about opens two closing, and switch is rapid, and sealability doubles than three valve oil well pumps, the pumping efficiency raising 10%-20% of oil well pump.
The cylinder side of the limited step below of the small piston in mobile piston of the present utility model and the fixed piston is other to have 2-6 oil inlet hole, and the best is 4 oil inlet holes.The other uniform oil inlet hole in small piston cylinder side, when plate valve and when opening, oil stream enters oil pipe fast from 4 uniform oil inlet holes, improves pumping efficiency.
