On, the upper surface of oil inlet valve seat keeps sealing after being compacted with the inner circular bead face of oil inlet valve bonnet, and the diameter of oil inlet valve ball is more than
The aperture of oil inlet valve seat, the upper end valve port fitted seal of oil inlet valve ball and oil inlet valve seat, linked hole, well are arranged at the top of oil inlet valve bonnet
Liquid energy is flowed upwards out from the top linked hole of the inside of oil inlet valve base joint, oil inlet valve seat through oil inlet valve bonnet, further includes level pressure pin
Nail, bott stick, bott stick pass through oil inlet valve base joint, oil inlet valve seat, the lower part of bott stick to block inlet valve seated connection from bottom to top
The lower inlet of head, prevents well liquid from being flowed by oil inlet valve base joint, the clogging oil inlet valve base joint in lower part of bott stick
When lower inlet, the upper end of bott stick jacks up oil inlet valve ball, prevents oil inlet valve ball from being located on oil inlet valve seat, and bott stick is by fixed
Pressing in pins is fixed on oil inlet valve base joint.
Sealing ring is installed, sealing ring is on level pressure pin, makes oil inlet valve seat between bott stick and oil inlet valve base joint
The well liquid of connector exterior cannot be flowed by the gap between bott stick and oil inlet valve base joint in oil inlet valve base joint.
The utility model has the beneficial effects that:The utility model be mounted on oil well pump pump barrel lower part, substitution it is existing into
Fuel tap, bott stick can block the lower inlet of oil inlet valve base joint, prevent well liquid from being flowed by oil inlet valve base joint, can be with
Prevent lower pump and when sucker rod well liquid by being sprayed in oil well pump, the utility model with arrived under oil pipe design position and under complete oil pumping
It after bar, is suppressed into oil pipe on ground, hydraulic coupling cuts level pressure pin, and bott stick, which is fallen into the reception device of lower part, can make pumping
Oil pump normal work oil pumping, the utility model is compared with prior art, simple in structure, and suppressing makes to fall behind formation under bott stick
Oil-well pump oil inlet valve is identical as existing oil-well pump oil inlet valve, can guarantee the reliability of oil well pump.
Description of the drawings
Fig. 1 is the assembly half sectional view of the utility model embodiment.
Specific implementation mode
First the embodiments of the present invention are illustrated in conjunction with Fig. 1 below.
As seen from the figure, the embodiments of the present invention include oil inlet valve ball 1, oil inlet valve bonnet 2, oil inlet valve seat 3, oil inlet valve seat
Connector 4, level pressure pin 6, bott stick 7, oil inlet valve ball 1 are placed in the valve chamber of oil inlet valve bonnet 2, and oil inlet valve seat 3 is mounted on oil inlet
In the valve seat orifice of valve bonnet 2, the top of oil inlet valve base joint 4 is connect with the lower thread of oil inlet valve bonnet 2, makes the upper of oil inlet valve seat 3
End face is withstood in the inner circular bead of oil inlet valve bonnet 2, and the upper surface of oil inlet valve seat 3 is compacted with the inner circular bead face of oil inlet valve bonnet 2
Sealing, the diameter of oil inlet valve ball 1 is kept to be more than the aperture of oil inlet valve seat 3, the upper end valve port of oil inlet valve ball 1 and oil inlet valve seat 3 afterwards
The top of fitted seal, oil inlet valve bonnet 2 has linked hole, well liquid can be from the inside of oil inlet valve base joint 4, oil inlet valve seat 3 through oil inlet
The top linked hole of valve bonnet 2 flows upwards out, and bott stick 7 passes through oil inlet valve base joint 4, oil inlet valve seat 3, bott stick 7 from bottom to top
Lower part block the lower inlet of oil inlet valve base joint 4, prevent well liquid from being flowed by oil inlet valve base joint 4, under bott stick 7
When the lower inlet of the clogging oil inlet valve base joint in portion 4, the upper end of bott stick 7 jacks up oil inlet valve ball 1, prevent oil inlet valve ball 1 from
It is located on oil inlet valve seat 3, it is ensured that in the pressure transmission on oil inlet valve bonnet 2 to bott stick 7, bott stick 7 is by level pressure
Pin 6 is fixed on oil inlet valve base joint 4.
The lower part of bott stick 7 is limited by the inner circular bead of oil inlet valve base joint 4, when bott stick 7 is by the upward pressure in lower part
When power, level pressure pin 6 is not forced, and well liquid pressure when going into the well outside oil inlet valve base joint 4 will not be such that level pressure pin 6 is cut
It is disconnected.
The further measure of the utility model is that sealing ring 5, sealing ring are installed between bott stick 7 and oil inlet valve base joint 4
5 on the level pressure pin 6, prevent well liquid oil inlet valve base joint 4 outside from by bott stick 7 and oil inlet valve base joint 4 it
Between gap flow into oil inlet valve base joint 4, when preventing from going into the well inside have high pressure.
The utility model is mounted on the pump barrel lower part of oil well pump, replaces existing inlet valve, bott stick 7 that can block oil inlet
The lower inlet of valve base joint 4 prevents well liquid from being flowed by oil inlet valve base joint, can prevent lower pump and well liquid when sucker rod
By being sprayed in oil well pump, the utility model with arrived under oil pipe design position and under after complete sucker rod, beaten into oil pipe on ground
Pressure, hydraulic coupling cut level pressure pin 6, and bott stick 7, which is fallen into the reception device of lower part, can make oil well pump normal work oil pumping, beat
Pressure keeps 7 times oil-well pump oil inlet valves for falling behind formation of bott stick identical as existing oil-well pump oil inlet valve.
