Description
Technical field
The utility model belongs to petroleum recovering technical field, relates under a kind of producing well in order to prevent tube corrosion fouling administration instillator under the producing well of long-term discontinuity administration in oil pick-up tube bottom adopts.
Background technology
The current down-hole at mechanical type producing well, in order to prevent tube corrosion and fouling, all to adopt to pre-install anticorrosion liquid in oil pick-up tube bottom, utilize wriggling the oozing in the water under pool liquid interruption of oil pick-up tube, but the amount of liquid medicine that the instillator of quite a few instils is unstable, and time little when large, even just liquid is not dripped off to the expected time of arrival, cause corrosion to equipment, cause well casing to damage ring.
Summary of the invention
Provide administration instillator under a kind of producing well in order to solve the problems of the technologies described above the utility model, object be accurate quantitative analysis instil, guarantee administration steady in a long-term.
For reaching administration instillator under above-mentioned purpose the utility model producing well, comprise valve body, in valve body, be provided with medicine hole, a side at valve body is provided with cavity, be provided with reciprocating push rod on the top of cavity, middle part at cavity is provided with connector, the bottom of cavity is provided with cock, the bottom of push rod is fixedly connected with connector, the top of straight pin is fixed in connector base apertures, between connector and cock, be provided with Compress Spring, connector bottom and straight pin are located in Compress Spring, in the shoulder hole of cock inside, be provided with inner sleeve, in the shoulder hole of inner sleeve top, be provided with sealing ring, be provided with down funnel shaped dripping hole at the center of inner sleeve, bottom at dripping hole is provided with steel ball, it below steel ball, is one end of flat spring, medicine hole is communicated with middle cavities, dripping hole communicates with middle cavities.
In the cavity of described connector top, be fixed with internal circlip, internal circlip top is fixed with the first Y shape rubber seal, and internal circlip and the first Y shape rubber seal are enclosed within on push rod.
Described connector and push rod are fixed by elastic cylindrical pin.
The bottom of described straight pin is spherical.
Described sealing ring is Y shape rubber seal.
The other end of described flat spring is fixed on the bottom of valve body.
The utility model has the advantages of: utilize plunger spherical head and Y type rubber seal and steel ball composition drip chamber, meet low discharge and instil.Utilize the fore-set of a Y type rubber seal and stainless bohler low roughness to coordinate, to guarantee to meet the sealing of long-term a large amount of axially reciprocating.Because the reciprocating frequency of push rod is constant, make straight pin be inserted into the frequency of Y type rubber seal constant, the frequency of backing down like this steel ball is constant, finally reaches accurate quantitative analysis and instils, and has guaranteed administration steady in a long-term.Simple in structure, working stability is reliable, easy to maintenance, can reuse for a long time.
