Description
Technical field:
The utility model relates to the rotary flow type standing valve of a kind of oil well pump, particularly oil well pump.
Background technique:
American Api standard oil well pump list ball valve fixation assembly, is made up of a ball valve, a ball seat, when liquid stream wash open ball valve enter pump chamber time, liquid stream is a kind of sand, gas-liquid mixture of bottom horizontal flow sheet, very easily forms sand card, gas lock.When plunger starts to run downwards to upper dead center, the fluid column instantaneous pressure in pump chamber is very large, and promote sphere and seal to ball seat, now ball may produce secondary bounce, when impact force is eliminated, could carry out nature sealing under the pressure of fluid column.Bounce to the sealing strip existence shock damage of ball seat, its it, sealing strip does not have sealing effect; In addition, seal delayed, some falls back to outside pump to make the stoste in pump chamber, causes pump efficiency to reduce.
Summary of the invention:
The utility model object is to provide a kind of rotary flow type standing valve that a kind of life-span is long and pump efficiency is high.
Realizing the technical solution of the utility model is a kind of rotary flow type standing valve, comprise shell, lower valve base and lower oil-release valve cover, sand anchor and pump joint, it is characterized in that: in the shell above lower oil-release valve cover, be also provided with upper valve base and upper oil-release valve cover, on this, the bottom of oil-release valve cover is provided with tapped hole and nut matches, upper valve base is placed in the step hole of outlet valve on this, upper valve ball is placed in the upper end-hole place of this upper valve base, the axial bore of nut, the axial bore of upper valve base is connected with the oil outlet on upper oil-release valve cover top, the oil outlet on upper oil-release valve cover top is communicated with the oil pocket of pump joint, the two ends rotating oar are rotatably supported in the upper end hole of pump joint and the blind hole at center, upper oil-release valve cover upper-end surface.
The utility model has long service life and the high remarkable advantage of efficiency compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
The utility model has following embodiment, the tapped hole of shell lower end and the outside threaded holes of sand anchor match, the first valve ball 3 is provided with at the first valve seat 2 aperture place of shell 1 lower end, hold on the housing in pump joint 9 hole of connection to be provided with and rotate oar 10, these two ends rotating oar are rotatably supported in the blind hole of pump joint stomidium and upper oil-release valve cover 8 upper end respectively, the outside thread of nut 5 and the step corresponding threaded holes of upper oil-release valve cover lower end, upper valve base is placed in the step hole above oil-release valve cover tapped hole, and upper valve ball 7 is placed in the upper end-hole place in this upper valve base 6 hole.On this, the top of oil-release valve cover is provided with oil outlet and is communicated with pump joint oil pocket, and the upper end of lower oil-release valve cover 4 is also provided with oil outlet.
Working principle of the present utility model is, fluid makes rotation oar rotate in pump chamber flowing, and fluid is by turn, and the sand in fluid, dirt are difficult to assemble, and gas is difficult to condense, and thus avoids sand card, sand buries and gas lock; The rotation rotating oar makes the impact force of liquid stream reduce, and avoids sealing strip and impacts the damage produced, thus improve the life-span, and meanwhile, the first valve seat adopts plastic material, this soft seal, only relies on the weight of ball self can realize sealing, so pump efficiency is higher.
