Description
The technical field is as follows:
the utility model belongs to the technical field of the oil production equipment technique and specifically relates to an automatic manual two effect blowout preventers and stuffing box.
Background art:
in the production process of pumping wells of various oil and gas field companies in China, manual flashboard well sealers are mostly adopted and automatic well sealers are not equipped, once a pumping well is out of control due to the fact that a sucker rod breaks off, oil and gas in a shaft can be sprayed out of the shaft without control, environmental pollution, oil and gas resource waste and adverse social effects are caused, and even fire explosion can be possibly caused.
The utility model has the following contents:
the utility model aims to solve the technical problem that an automatic manual double-acting blowout preventer and stuffing box that can realize that pumping well sucker rod takes off the back automatically well shut off absolutely, simultaneously can the manual well shut off is provided.
The technical scheme of the utility model is that: the utility model provides an automatic manual two effect blowout preventers and stuffing box, includes manual flashboard blowout preventer, manual flashboard blowout preventer upper portion sealing connection stuffing box, and the stuffing box includes packing section of thick bamboo, filler, gland and pressure cap I, is equipped with automatic shut-in device below the stuffing box and above manual flashboard blowout preventer.
Automatic well sealing device is including sealing the well chamber, seal well chamber one side and extend one section lopsided bypass pipe, be equipped with the piston in the bypass pipe, piston upper portion is compression spring and pressure cap II, pressure cap II and bypass pipe thread sealing connection, the piston lower part is the push rod, the push rod bottom is equipped with gyro wheel I, seal the well chamber and seal well lid one side in bypass pipe one side bottom hinged joint, the opposite side that seals the well lid is equipped with gyro wheel II, gyro wheel II supports on the sucker rod, gyro wheel I supports and covers the top at sealing, it has the sealing washer to bond to seal well lid below.
A compression spring is arranged between the pressing cap I and the packing gland.
When the well sealing cover falls down, the bottom of the well sealing cavity at the position of the roller II is provided with an empty groove.
And lubricating oil is filled in the well sealing cavity.
The utility model discloses following beneficial effect has: the manual flashboard blowout preventer can seal the well mouth when changing the packing and in emergency, and the automatic well sealing device takes place the sucker rod at the oil well and breaks off the automatic well mouth of sealing, prevents that the production accident from taking place, is equipped with compression spring between pressure cap and the gland for the packing is in the precompression state always, improves the sealing performance of well mouth.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-a manual flashboard blowout preventer, 2-a packing cylinder, 3-packing, 4-a packing gland, 5-a pressing cap I, 6-a sucker rod, 7-a blowout chamber, 8-a bypass pipe, 9-a pressing cap II, 10-a piston, 11-a push rod, 12-a roller I, 13-a blowout well cover, 14-a roller II, 15-an empty groove and 16-a sealing ring.
The specific implementation mode is as follows:
the present invention will be further explained with reference to the accompanying drawings:
as shown in figure 1, the automatic and manual double-acting well plugging device comprises a manual flashboard well plugging device 1, wherein the upper part of the manual flashboard well plugging device 1 is hermetically connected with a stuffing box, the stuffing box comprises a stuffing cylinder 2, stuffing 3, a stuffing gland 4 and a gland I5, and an automatic well plugging device is arranged below the stuffing box and above the manual flashboard well plugging device 1.
The manual flashboard blowout preventer 1 can seal a well mouth when a filler is replaced and in emergency, and the automatic blowout preventer can automatically seal the well mouth when the sucker rod 6 breaks off in an oil well, so that production accidents are prevented.
Automatic well sealing device is including sealing well chamber 7, seal well chamber 7 one side extends one section leaned up's bypass pipe 8, be equipped with piston 10 in the bypass pipe 8, piston 10 upper portion is compression spring and presses cap II9, press cap II9 and 8 threaded seal of bypass pipe to be connected, piston 10 lower part is push rod 11, push rod 11 bottom is equipped with gyro wheel I12, seal well chamber 7 seals well lid 13 one side at 8 one side bottom hinged joint of bypass pipe, the opposite side of sealing well lid 13 is equipped with gyro wheel II14, gyro wheel II14 supports on sucker rod 6, gyro wheel I12 supports in sealing well lid 13 top, it has sealing washer 16 to bond in sealing well lid 13 below.
When the sucker rod 6 is disconnected, the well sealing cover 13 loses the support that the roller II14 supports against the sucker rod 6, the well sealing cover 13 falls down to press the bottom of the well sealing cavity 7 under the action of the compression spring above the piston 10, and the sealing ring 16 is compressed to seal the well mouth.
A compression spring is arranged between the pressure cap I5 and the packing gland 4, so that the packing 3 is always in a pre-compression state, and the sealing performance of a wellhead is improved.
When the well sealing cover 13 falls down, the bottom of the well sealing cavity 7 at the position of the roller II14 is provided with a hollow groove 15 for accommodating the roller II14.
The well sealing cavity 7 is filled with lubricating oil to lubricate the roller II14 and to fill and improve the lubrication.
