Manage the lower end in described in the utility model first and be connected with pipe in second by first box cupling, the second interior pipe the other end connects described lower contact by second box cupling, and the described second interior pipe inside is equipped with gas bleeder valve.
Lower contact described in the utility model inside is equipped with center tube, and the sidewall of center tube is provided with a plurality of holes, and is divided into two-part up and down by dividing plate, and a part is provided with the baffle ring of a plurality of buffer functions; Another part is with tubular filter screen outward; Inside is equipped with one-way valve.
Oiling valve described in the utility model comprises fuel inlet fitting, valve seat, valve ball and has the valve cover in a plurality of holes, valve seat is installed in valve cover bottom, fuel inlet fitting is installed in valve cover lower end, valve seat is fixed between valve cover and the fuel inlet fitting, valve ball places on the valve seat, forms secondary sand setting district in the valve cover and first between the pipe.
The beneficial effects of the utility model:
1. fuel-displaced is that the side is fuel-displaced, and the foul that fluid can not carry does not influence pump work;
2. level oil flows and is provided with two sand setting structures, improves sand setting efficient;
3. the employing gas bleeder valve reduces oil flow resistance, has improved branch gas efficient;
4. novel in design, rational in infrastructure, to make simply, supporting use does not produce negative effect, prolongs pumping well effectively and is excused from a college course the phase.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
1 upper connection among the figure, 2 oil outlets, 3 valve balls, 4 first box cuplings, 5 second box cuplings, 6 lower contacts, 7 one-way valves, 8 tubular filter screen, 9 dividing plates, 10 gas bleeder valves, 11 secondary sand setting districts, 12 valve seats, 13 valve covers, 14 first interior pipes, 15 fuel inlet fittings, 16 center tubes, 17 baffle rings.
(5) embodiment
A kind of oil well pump protective gear as shown in Figure 1; comprise be used for the fixedly upper connection that is connected of oiling valve 1 of oil well pump, first in pipe 14, be used for the lower contact 6 that is connected with tail pipe; pipe 14 sides are provided with a plurality of oil outlets 2 in described first, and inside is equipped with oiling valve.
