Abstract
The utility model relates to a kind of shock cartridge type fixed valve ball opening devices.Mainly solve the problem of that existing oil well pump pump barrel and top crude oil in oil pipe when examining pump can not release.It is characterized by: being equipped with impacting tube (4) inside the outer cylinder (2), fixed valve ball (5) are equipped in impacting tube (4), valve bonnet (3) are connected at the top of impacting tube (4), impacting tube (4) bottom side, which is equipped with, hits pawl (8), hit the contact of incline plane of pawl (8) bottom and outer cylinder (2) inner wall, and the lower section on impacting tube inclined-plane is equipped with fixed valve base (6), fixed valve base (6) bottom is positioned by lower contact (7).Fixed valve ball can be opened by simply launching oil pumping club shaft operation in pump detection and workover, realize that pump barrel and top crude oil in oil pipe all release by the shock cartridge type fixed valve ball opening device.
Description
Technical field
The utility model relates to oil pump field, specifically a kind of shock cartridge type fixed valve ball opening device.
Background technique
Oil well pump is in pump detection and workover, since fixed valve ball is set in standing valve for oil-well pump assembly, pump barrel and top oil pipe
Interior crude oil can not release, and take ground to oil pipe and increase environmental protection construction risk and environmental protection equipment investment, while also reducing work
Industry construction efficiency.
Summary of the invention
In order to overcome existing oil well pump when examining pump, the deficiency that pump barrel and top crude oil in oil pipe can not release, this reality
A kind of shock cartridge type fixed valve ball opening device is provided with novel, the shock cartridge type fixed valve ball opening device is in pump detection and workover
When, fixed valve ball can be opened by shirtsleeve operation, realize that pump barrel and top crude oil in oil pipe all release.
The technical solution of the utility model is: a kind of shock cartridge type fixed valve ball opening device, including top connection, under connect
Head is connected between top connection and lower contact by outer cylinder, and the outer barrel is equipped with impacting tube, is equipped with fixed valve in impacting tube
Ball is connected with valve bonnet at the top of impacting tube, and the impacting tube bottom side, which is equipped with, hits pawl, hits the oblique of pawl bottom and outer tube inner wall
Face contact, while the lower section on impacting tube inclined-plane is equipped with fixed valve base, fixed valve base bottom is positioned by lower contact.
The utility model has the following beneficial effects: 1. cartridge type fixed valve ball opening device is hit in application, oil well pump is increased
Oil draining function is added, becoming can oil drain pump；2. oil well pump is during normal production, fixed valve ball set realized on fixed valve base it is close
The problem of envelope, does not influence pump efficiency, misses there is no bleeder rubber or metal sealing；3. not influencing to suppress the oil well pumps such as pump, well-flushing
Condition is pumped to verify, handle work；4. pump detection and workover needs draining, after sucker rod and plunger rise, launches 3m long 25mm and take out
Beam hanger is shorted, and realizes that fixed valve ball is opened by triggering impacting tube, pump barrel and crude oil in oil pipe can all release, and crude oil does not take to
Ground reduces environmental protection construction risk；5. draining simple process does not increase ground oil-collecting and processing equipment and relevant work amount,
Labor intensity of workers is greatly reduced, improves work efficiency, avoids the wasting of resources.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1- top connection in figure, 2- outer cylinder, 3- valve bonnet, 4- impacting tube, 5- fixed valve ball, 6- fixed valve base, 7- lower contact, 8-
Hit pawl.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, a kind of shock cartridge type fixed valve ball opening device, including top connection 1, lower contact 7, in top connection 1
Portion is connected with pump barrel, is connected between top connection 1 and lower contact 7 by outer cylinder 2, and impacting tube 4 is equipped with inside the outer cylinder 2, is hit
It hits and is equipped with fixed valve ball 5 in cylinder 4, be connected through a screw thread valve bonnet 3 at the top of impacting tube 4.4 bottom side of impacting tube is equipped with and hits
Pawl 8 is hit, pawl 8 is hit and is stretched out by 4 bottom of impacting tube, radially has certain elasticity, and hit in 8 bottom of pawl and outer cylinder 2
The contact of incline plane of wall.The lower section of outer cylinder 2 is equipped with fixed valve base 6, and 6 top of fixed valve base is stuck on the step of outer cylinder 2, and fixed valve
Seat 6 is contacted with fixed valve ball 5, and 6 bottom of fixed valve base is positioned by lower contact 7.
Oil well pump operate normally when, fixed valve ball 5 it is normally-open with set；When needing pump detection and workover, act sucker rod
With assembly for plunger, the 19mm oil pumping club shaft of 3-5m long is launched into pump barrel, oil pumping club shaft passes through 1 foot passage of top connection
Hitting valve bonnet 3 moves down impacting tube 4 by valve bonnet 3 force is transmitted on impacting tube 4, the shock of 4 bottom of impacting tube
Pawl 8 is popped up by the effect of 2 ramp of outer cylinder to center, is hit pawl 8 for fixed valve ball 5 and is pushed away center, to open solid
Determine the central passage of valve seat 6, pump barrel and top crude oil in oil pipe leak into pit shaft, realize draining.
