Abstract
The utility model discloses a pumping well polished rod sealer gate plate which comprises a rubber plate (1) and a gate core (2). The pumping well polished rod sealer gate plate is of a cylindrical structure, the right end of the gate plate is provided with a semicircular hole (E), the end face of the semicircular hole (E) is provided with a slot (A), three oil storage grooves (B) are formed in the semicircular hole, the rubber plate (1) wraps the three-step cylindrical steel gate core (2), the protruding part of the gate core (2) is provided with a guide groove (C), and the right end of the gate plate is provided with a hanging port (D). Through the gate plate, a packing is convenient to replace, the sealing performance is good, oil and gas are prevented from leaking and polluting the environment when the packing is replaced, the time for replacing the packing is shortened, the production rate of an oil well per hour is improved, and the yield of crude oil is increased.
Description
Technical field
the utility model relates to oil field machinery oil wellhead polish rod sealer accessory, particularly is a kind of pumpingh well polished rod sealer flashboard.
Background technology
are present, and in the oil field machinery oil manufacturing process, the upper and lower reciprocating motion through the pumpingh well polished rod drives sucker rod, deep well pump is extracted into ground with crude oil.The polished rod seal packing is a consumable accessory, needs often to change, and must close the rubber gate when changing packing; By flashboard sealed lower portion pressure, the existing narrow sealing area of flashboard is little, when bottom pressure is big; Can not excellent sealing; Cause the oil and gas leakage contaminated environment, prolong and change the packing time, influence oil well crude oil ordinary production.
Summary of the invention
The purpose of
the utility model is exactly to above-mentioned weak point, designs a kind of pumpingh well polished rod sealer flashboard, solves existing flashboard poor sealing, oil and gas leakage, the unhandy problem of replacing packing.
The purpose of
the utility model is realized by following technical proposals.
the utility model comprises: offset plate, lock core.Its pumpingh well polished rod sealer flashboard is a cylindrical structure, and right-hand member is provided with semicircle orifice, is used by two pairings; Polished rod therefrom passes through, and the semicircle orifice end face is provided with slot, plugs each other; Inside is provided with three road oil storage tanks, and three grades of stairstepping cylindrical steel body lock cores are surrounded by offset plate outward, and the part of on the lock core, protruding is provided with gathering sill; Right-hand member is provided with mouth hanging, so that articulate with valve rod.
The beneficial effect of
the utility model is: easy to operate when changing packing, good seal performance is avoided the oil and gas leakage contaminated environment, shortens the packing time of changing, and rate when improving oil well production increases crude output.
Description of drawings
Fig. 1-the utility model master looks the complete section structural representation.
Fig. 2-this practicality attaches the TV structure sketch map.
In
accompanying drawing, 1. offset plate, 2. lock core; A. slot, B. oil storage tank, C. gathering sill, D. mouth hanging, E. semicircle orifice.
The specific embodiment
Below in conjunction with accompanying drawing further elaboration is done in the enforcement of the utility model:
pumpingh well polished rod sealer flashboard comprises: offset plate 1, lock core 2.Its pumpingh well polished rod sealer flashboard is a cylindrical structure, and right-hand member is provided with semicircle orifice E, and semicircle orifice E end face is provided with slot A; Inside is provided with three road oil storage tank B; Be surrounded by offset plate 1 outside three grades of stairstepping cylindrical steel body lock cores 2, the part of protrusion is provided with gathering sill C on lock core 2, and right-hand member is provided with mouth hanging D.
