Embodiment
The utility model is described in further detail with example below in conjunction with the accompanying drawings：
Retrievable type Multipurpose standing valve for oil-well pump, as Figure 1-Figure 4, retrievable type Multipurpose standing valve for oil-well pump, including：
Top connection 1, lower contact 15 and fixed valve assembly.Fixed valve assembly includes fishing head 2, ejector sleeve 3, fixture block pipe 4, spring 5, valve card
Block 6, pin 7, support spring 8, valve bonnet 9, valve ball 10, valve seat 11, pressure cap 12, O-ring 13, O-ring 14.The retrievable type multipurpose
Standing valve for oil-well pump and fishing tool assembly are used cooperatively, and fishing tool assembly includes salvaging pipe 16, spring 17, salvages fixture block
18th, pin 19.
Seal with screwed joint between top connection 1 and lower contact 15, the inside of top connection 1 type ring groove with teeth, inside lower contact 15
There is a boss；It is threadedly coupled between fishing head 2 and fixture block pipe 4, is threadedly coupled between valve bonnet 9 and fixture block pipe 4, O-ring 13 seals,
Valve seat 11 is connected on valve bonnet 9 by the threaded connection between pressure cap 12 and valve bonnet 9；O-ring 14 between valve bonnet 9 and lower contact 15
Sealing；Connected between valve fixture block 6 and fixture block pipe 4 by pin 7, valve fixture block 6 can rotate around pin 7, valve fixture block 6 and ejector sleeve 4 it
Between have spring 5；Support spring 8 is between ejector sleeve 3 and valve bonnet 9.Valve ball 10 is in valve bonnet 9, above valve seat 12, fishing head
There is a boss 2 upper ends；Fishing tool assembly is connected in below oil pump plunger piston, is salvaged and is passed through pin between fixture block 18 and salvaging pipe 16
The connection of nail 19, salvaging fixture block 18 can rotate around pin 19, and salvaging between fixture block 18 and salvaging pipe 16 has spring 17.
Above-mentioned retrievable type Multipurpose standing valve for oil-well pump operation principle is as follows：
During work, top connection 1 and lower contact 15 link together and are connected to oil pump sleeve lower end.Fixed valve assembly
(as shown in Figure 2) not G.I.H in lower pump barrel.So, it is connection after complete under pump barrel, inside and outside whole tubing string, can be real
Now lead to the function of operation through tubing, such as steam injection, water filling, wash kill-job and sand washing.When needing oil-well pump to produce, in oil
It will be fixed in pipe in valve assembly launching trap, and well liquid is injected to oil pipe, in weight of standing valve assembly itself and well action of hydraulic force
Under, fixed valve assembly enters the cylindrical empty intracavitary that lower contact 15 and top connection 1 form, as shown in figure 1, passing through fixture block pipe 4
The internal boss of lower end and lower contact 15 realizes the lower limit of fixed valve assembly, by valve fixture block 6 in the presence of the elastic force of spring 5
Ejection, into the flute profile annular groove of top connection 1 in realize fixed valve assembly upper limit, the lower end of valve bonnet 9 is stretched into lower contact 15, passed through
Between O-ring 14 realize sealing, then tripping in sucker rod, oil pump plunger piston can realize normal production, fishing tool assembly
It is lowered into together with being connected with oil pump plunger piston in oil pipe.
After lower sucker rod, oil pump plunger piston are pumped, if there is fixed defective valve, or oil pipe well-flushing need to be carried out, oil
Pipe steam injection, it is necessary to which standing valve is salvaged to come during water filling in oil pipe.Now, polished rod is transferred, makes the salvaging of oil pump plunger piston lower end
(as shown in Figure 3) is advanced into fishing head 2 under instrument assembly, during fishing tool assembly is descending, pipe 16 is salvaged and pushes away
Pipe 3 is descending, in acting on for ejector sleeve 3, the compression spring 5 of valve fixture block 6, is rotated around pin 7, from the flute profile annular groove transfer of top connection 1
Go out, into fixture block pipe 4.Fixture block 18 is salvaged when by the upper end boss of fishing head 2 on fishing tool assembly, is compressed before this
Spring 17, which enters, to be salvaged in pipe 16, is then stretched out, is stuck at the boss of fishing head 2 in the case where being acted on by the elastic force of spring 17, will
When sucker rod, oil pump plunger piston propose oil pipe, fixed valve assembly is suggested in well (as shown in Figure 4) together therewith.It is now whole
It is connection when in oil pipe, if fixed defective valve, can put into new standing valve., also can be direct to carry out oil pipe operation tubing
Carry out, without carrying out lower oil tube operation again, not only reduce operating cost, and pumping production efficiency can be improved.
