Description
Technical field:
The utility model relates to the used a kind of packing box in oil recovery field, oil field, and particularly a kind of have a theftproof performance packing box.
Background technology:
Movable packing box is a kind of mode of oil field machinery oil wellhead polish rod sealing, is when being used for preventing the sucker rod up-down stroke, and the oil water mixture in the pit shaft runs off between packing box and polished rod.The kind that use in present oil field is dual mode substantially, a kind ofly adjust outstanding rope center of pumping unit horsehead and wellhead polish rod central seal by seal nipple sphere wallowing motion, another kind is that the flat seal plane is moved and adjusted horse head and hang rope center and wellhead polish rod central seal.Owing to often steal crude oil after having the oil field saboteur to dismantle the packing box gland, be found everywhere the situation of ejection oil water mixture contaminated environment to the management well site that makes troubles, not only having influenced normal oil recovery has also increased personnel labor.
The utility model content:
In order to solve the problem that background technology exists, the utility model provides a kind of theftproof performance packing box that has, and this is novel to have reliable operation, and sealing performance is strong, simple to operate, safe characteristics.
The technical solution of the utility model is: this has the theftproof performance packing box and comprises the bottom connector, the bottom connector is connected with well head wax removal rubber gate, and the packing cover is arranged in the connector of bottom, is placed with the rubber packing in the packing cover, packing has put and has compressed plug, compresses the hole that one group of correspondence is arranged on the plug.
The utlity model has following beneficial effect: basis is novel to be used by field trial, has following beneficial effect: anti-theft feature: be provided with packing unit in the connector of bottom and compress the plug cooperation, when the saboteur dismantles the packing box gland and drains the oil, packing in the ball seat keeps sealing state with polished rod all the time, do not have special tool to open, oil water mixture can not spray from packing box in the pit shaft.The utility model reliable operation, sealing performance is strong, and simple to operate, safety is that present rod-pumped well is suitable for antitheft packing box, has a extensive future.
