Abstract
The utility model provides an improved generation valve cover that moves about, includes that the upper shield connects (1), the valve casing body (2), the valve ball 3, disk seat (4), goes out oil chamber (5), valve ball chamber (6), its characterized in that: the upper cover connects (1) and is connected with the valve bonnet body (2), the valve bonnet body (2) is connected with disk seat (4), be equipped with in the valve bonnet body (2) and have valve ball chamber (6), it is connected with valve ball chamber (6) to go out oil chamber (5), install valve ball (3) in valve ball chamber (6), the wall thickness of going out oil groove valve cover lacing wire has been increased, the bearing capacity of lacing wire has been improved, the grinding of valve ball to valve cover lacing wire has been stopped simultaneously, fatigue fracture has been reduced, the life of extension valve cover.
Description
Technical field
The utility model relates to the last travelling valve cover in the oil recovery well tubing pump, specifically, is a kind of modified model travelling valve cover.
Background technique
The valve ball chamber of conventional travelling valve cover with go out oil pocket one each other, at first in structural design with add the influence that is subjected to factor aspect two man-hour, objectively having caused the travelling valve cover is one of position of the easy-rupturing of sucker rod string; The one, the external diameter of valve cover must not be necessary for valve ball simultaneously again and reserve enough take-off spaces greater than the external diameter of plunger, so the valve bonnet wall thickness is thinner than plunger wall thickness (7.75mm), only is 5.5mm; The 2nd, the valve cover must set out oilhole, and for oily stream provides unimpeded passage, so valve is covered with and imitates loaded area and reduce, and bearing capacity descends, and causes stress to be concentrated easily and causes fracture.When secondly conventional travelling valve covers on the deep-well pump operation, the moment that valve ball is opened, under the liquid flow impact of high speed and high pressure, the impact valve cover that valve ball makes progress violent continuously go out oil pocket, make cylindrically to go out oil pocket and become rugby shape, it is big that internal diameter becomes, the wall thickness attenuation of flowing hole section, produce degradation failure, caused the fracture of valve cover.
Summary of the invention
The purpose of this utility model is to provide a kind of modified model travelling valve cover, it is at going out the easily broken problem of oil groove lacing wire wearing and tearing in conventional travelling valve cover structure design deficiency and the running, increased the wall thickness that the lacing wire of oil groove valve cover, improved the bearing capacity of lacing wire, stopped the grinding of valve ball simultaneously to the lacing wire of valve cover, reduce fatigue fracture, prolonged the working life of valve cover.
The utility model is achieved in that and comprises shield joint 1, valve bonnet body 2, valve ball 3, valve seat 4, goes out oil pocket 5, valve ball chamber 6, last shield joint 1 is connected with valve bonnet body 2, valve bonnet body 2 is connected with valve seat 4, be provided with valve ball chamber 6 in the valve bonnet body 2, go out oil pocket 5 and be connected, valve ball 3 is installed in the valve ball chamber 6 with valve ball chamber 6.
Separate by isolating plate 7 with going out between the oil pocket 5 in valve ball chamber 6.
Advantage of the present utility model is:
1., valve ball chamber and the development that goes out oil pocket separated type travelling valve cover; By Field Research and desk research, with the valve ball chamber of former travelling valve cover with go out oil pocket and make split type, utilize screwed connection, be separated by quincunx isolating plate, do not enter the oil pocket that of valve cover when making the valve ball take-off, solved frequent impact and the grinding loss of valve ball going out the oil groove lacing wire.
2., the oil outlet end that strengthens the valve cover faces the wall and meditates thickly, improves valve cover self-bearing capacity, reduces valve cover fracture probability.
3., select high-tensile and corrosion resistant material for use, further improve the corrosion resistance and the tensile strength of valve cover.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, comprise shield joint 1, valve bonnet body 2, valve ball 3, valve seat 4, go out oil pocket 5, valve ball chamber 6, last shield joint 1 is connected with valve bonnet body 2, valve bonnet body 2 is connected with valve seat 4, be provided with valve ball chamber 6 in the valve bonnet body 2, go out oil pocket 5 and be connected, valve ball 3 is installed in the valve ball chamber 6 with valve ball chamber 6.
Modified model travelling valve cover is by constituting with valve ball chamber two-part, goes out oil pocket and by screwed connection, wherein the valve ball chamber comprises valve ball, valve seat, plum blossom baffle plate; Go out oil pocket by last shield joint, go out oil groove and lacing wire is formed.
By Field Research and desk research, do not influencing valve ball 3 commencing heights (15mm) and going out under the oil condition, former travelling valve cover is lengthened to 195mm by 115mm, simultaneously with the valve ball chamber 6 of travelling valve cover with go out oil pocket 5 and make split type, utilize screwed connection, be separated by quincunx isolating plate 7, what do not enter the valve cover when making valve ball 3 take-offs goes out oil pocket 5, directly do not contact with the fuel-displaced end face of valve cover, solved 3 pairs of valve balls and gone out the frequent impact of oil groove lacing wire and grind loss.
Strengthening the oil outlet end of valve cover faces the wall and meditates thick
The fuel-displaced end face cell wall of Ф 38 valve covers after improving is increased to 7mm by 5.5mm, and valve cover self-bearing capacity improves 27%, reduces valve cover fracture probability.
Claims (3)
1, a kind of modified model travelling valve cover, comprise shield joint (1), valve bonnet body (2), valve ball 3), valve seat (4), go out oil pocket (5), valve ball chamber (6), it is characterized in that: go up shield joint (1) and be connected with valve bonnet body (2), valve bonnet body (2) is connected with valve seat (4), be provided with valve ball chamber (6) in the valve bonnet body (2), go out oil pocket (5) and be connected, valve ball (3) is installed in valve ball chamber (6) with valve ball chamber (6).
