Abstract
The utility model relates to a straight-flow zero-thrust compensator, which at least comprises a water vapor storage tank and a shell consisting of a flange, a large stuffing chamber with a sealing material injecting hole and a small stuffing chamber with a sealing material injecting hole, an extension tube with a small stuffing chamber, a rear connecting tube with a flange, a large sealing gland, two small sealing glands, sealing filler, a worm and a nut and the like. The utility model is convenient to operate, agile to install and can block under pressure. And when the straight-flow zero-thrust compensator leaks as a result of excessive wear, the sealing material can be compensated online so as to avoid emergency shutdown.
Description
Technical field
The utility model relates to a kind of direct current type thrustless compensator; It is a kind of heat distribution pipeline compensation device; Especially eliminate the effect of blind plate power that the medium internal pressure produces elbow or blind plate through the cooperative action by 3 packing seal positions of calculation Design, and the volume that reduces the heat distribution pipeline fixed bearing is realized a kind of direct current type thrustless compensator of nose balance simultaneously to fixed bearing.
Background technique
Slip-type expansion joint is widely used a kind of compensation of pipeline device in the modern heat distribution pipeline; Sleeve expansion joint relies on the core pipe to realize the heat distribution pipeline nose balance with respect to stretching of filler chamber; Because ordinary cartridge formula compensator can not be eliminated the effect to fixed bearing of blind plate power that the medium internal pressure produces elbow or blind plate; The huge blind plate power of increase generation along with heat distribution pipeline pressure and bore; The effect that huge fixed bearing supports blind plate power and other power need be set, cause the bigger increase of capital construction cost; And ordinary cartridge formula compensator in the course of the work, and core tube wall has relative movement with the sealing material that matches, and must cause the wearing and tearing of sealing material, leaks easily, needs to shut down the replacing sealing material.Existing technology Chinese patent number 92222994.5 disclosed " N-H-II type direct current type thrustless compensators " have through the cooperative action that 3 packing seal positions are arranged of calculation Design eliminates the effect to fixed bearing of blind plate power that the medium internal pressure produces elbow or blind plate; And the volume that reduces the heat distribution pipeline fixed bearing is realized nose balance simultaneously; But this N-H-II type direct current type thrustless compensator is after the sealing material excessive wear; After can only waiting to shut down; Could reply normally after changing sealing material, and length of installation is longer, arranges in the inconvenient well.Because heat distribution pipeline shutdown maintenance easily in running moves and the pressure sealing requirement so existing technology can't realize heat distribution pipe network fully reliably and with long-term.
Summary of the invention
The existing technology that is primarily aimed at the utility model can not realize the operation reliably and with long-term and the pressure sealing requirement of heat distribution pipe network fully; A kind of improvement structure is proposed; Can prevent take place to leak and make that the pipeline medium is excessive stops in emergency in the sealing material excessive wear; Can online easily additional sealing material, can continue a kind of direct current type thrustless compensator of long-time running.
The utility model is realized technical goal through following technical proposals.
A kind of direct current type thrustless compensator is made up of little filler chamber (4), little sealing gland (3), the back connecting tube (1) with big flange, standing screw (5), nut (2), the sealing material members such as (10) in water storage steam pipe (9), telescopic pipe (11), the big filler chamber (8) in band notes sealing material hole, big sealing gland (7), band notes sealing material holes (6).Its improvements are: be evenly equipped with threaded notes sealing material hole (6) on affiliated big filler chamber (8), little filler chamber (4) and the corresponding outer wall of sealing material (10), each is annotated sealing material holes (6) and seals with plug screw; Totally two of the little filler chamber (4) in said band notes sealing material holes (6), a right-hand member that is welded in water storage steam pipe (9), another is welded in the left end of telescopic pipe (11); Said band is annotated (8) one of the big filler chamber in sealing material holes (6), is welded in the left end of water storage steam pipe (9).
A kind of direct current type thrustless compensator of said structure is provided with 3～40 according to the latus rectum size and annotates sealing material hole on filler chamber's outer wall, inject the private closure material to satisfy from different directions through pressure.Said private closure material is paste or powdery.
The utility model compared with prior art has following beneficial effect:
1, be evenly equipped with threaded notes sealing material hole on the corresponding outer shell outer wall of filler chamber and sealing material, again can online easily additional sealing material after the sealing material excessive wear, can continue long-time running.
2, band is annotated totally two of the little filler chamber in sealing material hole, a right-hand member that is welded in the water storage steam pipe, and another is welded in the left end of telescopic pipe; More reasonable than prior art constructions; Shorten the length overall of direct current type thrustless compensator, be convenient to mounting arrangements, and improved the rigidity of compensator.
Description of drawings
Shown in the drawings is the utility model structural profile schematic representation.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
A kind of direct current type thrustless compensator shown in the drawings; Little filler chamber (4), little sealing gland (3), the back connecting tube (1) with big flange, standing screw (5), nut (2), sealing material members such as (10) by the big filler chamber (8) in water storage steam pipe (9), telescopic pipe (11), band notes sealing material holes (6), big sealing gland (7), band notes sealing material holes (6) are formed; Band is evenly equipped with threaded notes sealing material hole (6) on the big filler chamber (8) of the utility model, little filler chamber (4) and the corresponding outer shell outer wall of sealing material (10); On big filler chamber (8) and little filler chamber (4) outer wall, be provided with 3～40 according to the latus rectum size and annotate sealing material hole (6), each is annotated sealing material hole (6) and seals with plug screw.
Embodiment is mounted on the hot water pipeline of certain Thermal Corp; Its latus rectum is a kind of direct current type thrustless compensator of 1200mm, annotates and is provided with 24 on sealing material holes (6) and corresponding sealing plug screw and little filler chamber (4) outer wall and annotates sealing material holes (6) and corresponding sealing plug screw being provided with 32 on big filler chamber (8) outer wall.Through operation after a while; Sealing material (10) must have mechanical abrasion; When sealing configuration takes place to leak; Laying down the sealing plug screw of annotating on the sealing material hole (6) under the not shutdown situation successively, and from annotate sealing material hole (6), injecting the private closure material, annotating the notes sealing material holes (6) of private closure material and will in time seal with plug screw.Make sealing configuration reply sealability through online injection private closure material, satisfied the requirement of heat distribution pipe network pressure sealing in service.Private closure material in the utility model is paste or powdery sealing material, and good fluidity is prone to fill in, and is high temperature resistant.
