Description

Throttle float collar of tail pipe hanger

Technical Field

The utility model relates to a float collar, concretely relates to liner hanger throttle float collar.

Background

Use the oil equipment in oil development, these oil equipment can let the exploitation of oil more high-efficient and convenient, rely on the oil equipment can be very big promote oil development's efficiency, the needs that different oil development operating mode was used have been satisfied, can use a lot of spare parts when the oil equipment used, especially, involve and use the hanger, the hanger can need be provided with the pipe behind when using, be provided with the float collar on the pipe, the float collar can be fine let in the pipe is fit for the liquid of the different degree of depth, but float collar structure among the prior art is single, can not be fit for the use in the different liquid.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a tail pipe hanger throttling floating hoop which can lead the floating hoop to be suitable for different liquid level depths.

The utility model discloses a following technical scheme realizes: the utility model provides a liner hanger throttle float collar, is provided with the float collar body, the float collar body includes float collar inner circle and float collar outer lane the float collar body on be provided with the locking part that is used for locking, the outside of float collar inner circle be provided with the float collar outer lane, be provided with the float ware between float collar inner circle and float collar outer lane for the float ware that floats with the float collar relies on the clamp setting between float collar inner circle and float collar outer lane, the float ware be the float ball, it has the air just to pack in the inside of float ball the float ball rely on the clamp to fix in the cavity that forms between float collar inner circle and float collar outer lane.

The floating ball adopts the rubber ball of thick skin, is provided with the inner groovy of adaptation clamp on the outer wall of rubber ball, relies on the inner groovy to make the floating ball fixed firm in can assembling into the clamp.

The lower slot that is used for the adaptation balancing weight is provided with to the below of floating hoop body, lower slot rely on welded fastening at the lower extreme of floating hoop body, just lower slot be the open column structure in both ends.

The balancing weight adopt the lead block just the appearance and the mutual adaptation of slot down of lead block, be provided with the pull handle in the outside of lead block, rely on the pull handle can realize taking out back and forth of lead block.

The utility model has the advantages that: if need float the operation with the floating hoop when using, just need install the floating ball on the floating hoop, the buoyancy that can rely on the floating ball floats the clamp, can be fit for the needs of the use of shallow water level when floating, when needs use the deep water level with the floating hoop, can pull down the floating ball, then install the lead piece in the slot down, the gravity of dependence lead piece that can be fine, sink the floating hoop to the deep water level in, make the floating hoop fit for the use needs of different liquid level depths.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic view of the floating ball of the present invention.

Fig. 3 is a schematic view of the counterweight of the present invention.

In the figure: 1 is the float collar inner circle, 2 is the float collar outer lane, 3 is locking part, 11 is the floating ball, 12 is the inner groovy, 21 is lower slot, 22 is the balancing weight, 23 is the pull handle.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

The utility model provides a liner hanger throttle float collar, is provided with the float collar body, the float collar body includes float collar inner circle 1 and float collar outer lane 2 the float collar body on be provided with the locking part 3 that is used for locking, the outside of float collar inner circle 1 be provided with float collar outer lane 2, be provided with the flotation device between float collar inner circle 1 and float collar outer lane 2 for the flotation device that floats with the float collar relies on the clamp setting between float collar inner circle and float collar outer lane, the flotation device be float ball 11, it has the air just to fill in the inside of float ball 11 the float ball 11 rely on the clamp to fix in the cavity that forms between float collar inner circle 1 and float collar outer lane 2.

The locking part that sets up on the float collar body adopt locking hole and locking bolt, the locking hole set up at the top of float collar body just locking downthehole insert the locking bolt, be provided with W shape recess on the locking bolt the locking downthehole packing have the adhesive tape, the outer terminal surface adaptation W shape recess of adhesive tape can realize the meshing in locking bolt and the locking hole.

Floating ball 11 adopts the rubber ball of thick skin, is provided with the inner groovy 12 of adaptation clamp on the outer wall of rubber ball, relies on inner groovy 12 to make floating ball 11 fixed firm in can the assembly income clamp, because the packing has the air in the floating ball 11 adopts, can let floating hoop rely on floating ball 11 to float the floating hoop when using. The below of float collar body is provided with lower slot 21 that is used for adaptation balancing weight 22, lower slot 21 rely on welded fastening at the lower extreme of float collar body, just lower slot 21 be the open column structure in both ends, when needs let float collar be fit for the deep water region, can demolish floating ball 11, then assemble balancing weight 22 in lower slot 21, realized the sinking operation of float collar.

Balancing weight 22 adopts the lead block just the appearance of lead block and the mutual adaptation of slot 21 down be provided with pull handle 23 in the outside of lead block, rely on pull handle 23 can realize making a round trip of lead block to take out, balancing weight 22 can be at any time pack into and dismantle, rely on pull handle 23 when packing into and dismantling, can be fine realize packing into at any time and dismantle of lead block for the availability factor of float collar obtains effectual promotion.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
