Chamber is equipped with the valve cover 7 for limiting to valve seat 8, and valve cover 7, will be all through being threadedly connected to the upper lumen of lower contact 9
Your seat 8 is limited to the inner cavity of lower contact 9, after the utility model is converted into common fixed valve, does not reduce fixed valve performance, described all
You cover the 7 a certain number of longitudinal grooves of top Milling Machining, so that it can radially be opened and closed under certain condition, to change top
Interior latus rectum, the inner cavity of the top connection 2 are equipped with push rod 1, and push rod 1 penetrates from bottom to top from the inner cavity of top connection 2, and is above connect
First 2 interior step limit, is additionally provided in the inner cavity of top connection 2 for push rod 1 between the push rod 1 and valve cover 7
The spring 5 of support is provided with valve ball 6 above 1 lower lumen of push rod and valve cover 7, and valve ball 6 can be in 1 lower part of push rod
Inner cavity and 7 enclosed space of valve cover in activity.
In the present embodiment, the push rod 1 is provided with longitudinal groove, and its underpart is supported by spring 5, upwards by inside top connection 2
Step limit；1 lower lumen lower section internal diameter of push rod is isometrical in the 7 free outer diameter in top of valve cover, and it is radial to limit 7 top of valve cover
Expansion；1 lower lumen upper section internal diameter of push rod is significantly greater than the 7 free outer diameter in top of valve cover, allows 7 top radial dilatation of valve cover
To change latus rectum in 7 top of valve cover.
In the present embodiment, the top connection 2 is fixed with draining pin 3 laterally through 4 detent of C-shaped clamp spring, and draining pin 3 is worn
The longitudinal groove for crossing push rod 1 extends in 1 central passage of push rod, and stress slot is provided on draining pin 3, and be impacted Shi Kecong stress
Fracture realizes that oil pipe aerial drainage, draining pin 3 are connect with 2 flank threads of top connection at slot, and outside is limited by C-shaped clamp spring 4.
In the present embodiment, the top of the top connection 2 is externally provided with the external screw thread for connecting oil well pump, the lower contact 9
Lower part in be equipped with internal screw thread for connecting lower part oil pipe.
In the present embodiment, as shown in Figure 1, being located on 7 top of valve cover under 6 armed state of the valve ball, under push rod 1
The inner cavity in portion, the outer diameter of valve ball 6 is slightly larger than the free internal diameter at the top of valve cover 7, and valve ball 6 is supported by valve cover 7, Bu Nengjie
Valve seat 8 is touched, liquid can cross valve ball 6 through the top longitudinal groove of valve cover 7, flow downward realization across valve seat 8
Pump pressure transmission is crossed, lower part fluid power packer is set.
In the present embodiment, as shown in Figure 2 and Figure 3, after crossing pump pressure transmission operation, lower sucker rod and oil pump piston, oil pumping
Hit the top of push rod 1 under pump piston, 1 downlink compressed spring 5 of push rod, when 1 downward storke of push rod is enough, 1 lower lumen upper section of push rod
When reaching 7 top of valve cover, 1 lower lumen upper section internal diameter of push rod is substantially greater than the 7 free outer diameter in top of valve cover, 1 lower part of push rod

Oil pipe largely flows out well head, i.e. the aerial drainage principle of the utility model.
It should be understood that crossing the shape and dimensioned mode of the rubber seal of pump transmitting pressure tool, draining pin 3, no
In the protection scope of this patent, it will not go into details.
Relational language: 1) it sets: conversion process of the packing mouthpart class tool from armed state to working condition；2) pump is crossed to pass
Pressure: it is hydraulic to the lower transmitting of pump that high-pressure fluid crosses oil well pump；3) fluid power packer: the packing set using hydraulic strength as power
Device.
The utility model replaces the fixed valve of former oil well pump, when pumping packer fluid power being needed to set, from well mouth oil pipe plus
Internal pressure, pressure can cross the packer that oil well pump is passed down under pump, be allowed to normal fluid power and set, after setting, under
Sucker rod hits the utility model with oil pump piston, and the utility model is converted into common fixed valve auxiliary oil well pump and completes to recover the oil
Function after proposing sucker rod and piston, can throw the draining pin 3 that bar hits the utility model, realize pipe column oil drainage function.
This crosses pump transmitting pressure tool, has the following prominent advantages:
1) standard ball seat is used, is converted to after common ball seat equivalent with original pump fixed valve；
2) hanging steel ball is squeezed into ball seat and needs certain stroke and thrust, bores at the fast speed and when percussion drill is not vulnerable；
3) oil draining function is integrated, oil pipe can reduce tubing string complexity with pressure release when playing pump；
4) structure is simple, is easy to repair or restore its function.
The above are merely preferred embodiments of the present invention, it is noted that for those skilled in the art,
Without departing from the concept of the premise utility, several modifications and improvements can also be made, these also should be considered as practical
Novel protection scope, these all will not influence the effect and patent practicability of the utility model implementation.
