Background technique
Underwell anti-injection tool kind is more at present, such as turnover plate type valve, float-type valve etc., but all there are some problems,
For example the spring in turnover plate type valve cover board is easy to produce fatigue and leads to failure mechanisms, cannot achieve secondary blowout prevention, when lift pipe string
Overflow can be generated；Float-type valve is more demanding to the cleannes of sealing surface, and underground adaptability is poor, when being unable to ensure lift pipe string
Without overflow.Tripping in test equipment is needed to carry out survey tune in addition, rod-pumped well is subsequent, accordingly, it is desirable to provide a kind of novel anti-spray work
Tool, can provide TCH test channel and be able to achieve effective blowout prevention again.
Summary of the invention
The object of the present invention is to provide annulus logging can be thus achieved to be able to achieve again during lower tubular column without overflow
A kind of inclined cover board valve for pumping unit monitoring well.
The present invention is achieved by the following technical solutions: it by upper guide head, top connection, upper center tube, anti-rotation pin,
Pressure cap, upper connecting cylinder, spring, fixed ring, guide rail pin, lower connecting cylinder, lower center tube, sealing drum, connecting tube, pushing cylinder, cover board
Seat, fixing pin, italic, pre-tightens pin, position-limitting pin, guide pin, cap hinge axle composition at cover board；Wherein upper center tube with
Guide head is threadedly coupled, and upper connecting cylinder is threadedly coupled with top connection and is fixed by anti-rotation pin, pressure cap and upper center tube screw thread
Connection, spring are placed between upper center tube and upper connecting cylinder, and Fixing shrink ring is fixed on upper center tube and through guide rail pin, under

Connection, connecting tube lower end are threadedly coupled with cover board seat, and sealing drum is threadedly coupled with pushing cylinder and is fixed by anti-rotation pin, and cover board is set
Between cover board seat and italic, cover board is held out against by pre-tightening pin, and italic and pushing cylinder are connected and fixed by fixing pin, spacer pin
Nail is screwed on pushing cylinder, and lower center tube is connect with pushing cylinder by guide pin, and cap hinge axle is placed in the top of cover board.
Lower center tube lower end is designed as inclined-plane；Deck design is oblique angle 40-50 degree.
Compared with the prior art the present invention has the advantages that
The configuration of the present invention is simple is reasonable, cover board can be completed without spring mechanism, long service life suitable for pumping unit monitoring well
The control for crossing annulus logging with overflow in well during lower tubular column in pumping unit monitoring well production process.Lower center tube lower end
It is designed as inclined-plane, increases the contact area with cover board；Deck design is oblique angle 40-50 degree, is conducive to cover board opening and closing.
