Abstract
The utility model discloses a pump well backwater mechanical type uniflow valve, which comprises an upper connector, a lower connector, an outer pipe, a valve sleeve, a plunger, and a spring, wherein the outer pipe is provided between the upper connector and the lower connector, the valve sleeve is provided in the outer pipe, the upper end of which is connected with the upper connector, the valve sleeve is provided with the plunger, and the upper portion of the plunger is provided with the spring. The utility model has wide utilization, and the seal performance which is not influenced by assembling modes, which is widely applicable in oil production or gathering process of oil exploitation.
Description
One, technical field
The utility model relates to valve, relates in particular to the anti-mechanical type ball-and-seat that pours in down a chimney of a kind of pumpingh well.
Two, background technology
In the oil exploitation process, in mechanical pumpingh well manufacturing process,, pipe network crude oil can occur producing when serious and pour in down a chimney backflow stratum phenomenon especially, cause serious economy loss from pit shaft because the wearing and tearing of the in debt or oil pumping facility on stratum often produce leakage.Though existing ball-valve type ball-and-seat also can play the effect of anti-backflow, there is following shortcoming or deficiency:
1, service condition is limited, must be installed on the person in charge, otherwise be difficult for sealing, does not have the anti-effect of pouring in down a chimney;
2, in the manufacturing process, if sand production, ball seat easily produces long-pending sand, causes to be not closed completely;
3, valve ball and valve seat easily produce the bad or corrosion and damage of thorn, cause and close difficulty.
Three, summary of the invention
The purpose of this utility model provides the anti-mechanical type ball-and-seat that pours in down a chimney of a kind of improved pumpingh well.Shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art prevent that effectively the stratum from pouring in down a chimney, and improve exploitation effect, increase economic efficiency.
The anti-mechanical type ball-and-seat that pours in down a chimney of pumpingh well described in the utility model, comprise upper and lower joint, outer tube, valve cylinder, piston and spring, described outer tube is installed between upper and lower joint, described valve cylinder is installed in outer tube, its upper end is connected with top connection, be installed on piston in the valve cylinder, piston top is installed on spring.
Wherein, offer flowing hole on described valve cylinder lower end and the perisporium.Described piston is a hollow structure, installs in valve cylinder, and top is located mutually by the spring of installing on it, and the lower end is a blind hole, offers the flowing hole that is connected with hollow on the perisporium.
The utility model has following advantage compared with prior art:
1, applied range can be used on being responsible for, and also can use on outer tube;
2, simple and reasonable for structure, effective, prevent that effectively the stratum from pouring in down a chimney the generation of phenomenon, improved oil well production efficient.
Four, description of drawings
Accompanying drawing is the utility model structural representation.
Five, the specific embodiment
Referring to accompanying drawing, the anti-mechanical type ball-and-seat that pours in down a chimney of a kind of pumpingh well, comprise upper and lower joint, outer tube, valve cylinder, piston and spring, outer tube 5 is installed between upper and lower joint 1,6, valve cylinder 4 is installed in outer tube, its upper end is connected with top connection 1, is installed on piston 3 in the valve cylinder 4, and piston top is installed on spring 2.Offer flowing hole on valve cylinder 4 lower ends and the perisporium.Piston 3 is a hollow structure, installs in valve cylinder 4, and top is located mutually by the spring of installing on it 2, and the lower end is a blind hole, offers the flowing hole that is connected with hollow on the perisporium.
Claims (3)
