Abstract

The utility model discloses a special compensator of powder feeding pipeline belongs to the pipeline field. The technical problems to be solved in the utility model are: current compensator abrasion resistance is relatively poor, very easily leads to because the problem of revealing of wearing and tearing appearance. The utility model provides a special compensator of powder feeding pipeline, including the core pipe, the sealing flange, the adjusting sleeve, a housing, the spacer flanger, the sealing washer, the pull rod, baffle and dog, open flutedly on the casing, install sealed snare in the recess on core pipe, the sealing washer both sides are equipped with the adjusting sleeve, the sealing flange is installed respectively at the both ends of adjusting sleeve, the spacer flanger welding is on the casing, sealing flange and spacer flanger pass through the pull rod and connect, and through the nut fastening, the baffle passes through bolt and sealed flange joint, the dog welding is on the core pipe. The beneficial effects of the utility model are that, the compensator is heat -resisting, wear -resisting, sealing performance is better.

Description

Powder feeding pipes dedicated compensator
Technical field
The utility model belongs to pipeline field, in particular to a kind of powder feeding pipes dedicated compensator.
Background technology
Expansion joint is mainly used in powder feeding pipes and pipeline has the pipeline of relatively galling, conventional expansion joint generally by thin-wall corrugated tube as the flexible part absorbing displacement. Application number be 201420179819.4 Chinese patent disclose a kind of pipeline compensator, this loop expansion pipe by arranging bellows body between the ring flange at two ends, and the flange at two ends is connected by pull bar again, thus, when pipeline expands with heat and contract with cold, corrugated tube can alleviate it to the damage of pipeline. But this kind of design due to wear resistance poor, very easily cause due to the problems such as the leakage that occurs of wearing and tearing.
Practical novel content
The purpose of this utility model is to provide less, the good powder feeding pipes dedicated compensator of sealing property of a kind of friction.
For achieving the above object, the utility model adopts following technical scheme:
The utility model powder feeding pipes dedicated compensator, comprise core pipe, tongued and grooved flanges, adjusting sleeve, housing, middle flange, sealing-ring, pull bar, baffle plate and block, housing has groove, the sealing-ring being arranged in groove is enclosed within core pipe, sealing-ring both sides are provided with adjusting sleeve, the two ends of adjusting sleeve are separately installed with tongued and grooved flanges, middle flange is welded on housing, tongued and grooved flanges and middle flange are connected by pull bar and to pass through nut fastening, baffle plate is connected with tongued and grooved flanges by bolt, and block is welded on core pipe.
The utility model powder feeding pipes dedicated compensator difference from prior art is: one is that by adopting, the kinetic friction of sealing-ring and core pipe replaces corrugated tube as the parts of extraction duct displacement to the utility model, compensate the axial displacement of pipeline, make powder feeding pipes thermosteresis and fluid resistance less, simultaneously, tongued and grooved flanges can be regulated by pull bar and then regulate the sealing-gap between sealing-ring and core pipe, ensure good sealing-gap; Two is that the utility model loop expansion pipe is provided with for preventing the block reversed. Block ensure that can only axial displacement between core pipe and housing, can not have circumferential rotation, thus increases the reliability of sealing-ring.
The utility model powder feeding pipes dedicated compensator, also comprises spring pad, and spring pad is enclosed within pull bar and between nut and tongued and grooved flanges.
Mounting spring pad between nut and tongued and grooved flanges, sealing better effects if.
The utility model powder feeding pipes dedicated compensator, described sealing-ring cross section is in " mountain " font.
This kind of design formed sealing by the distortion extruding of the distortion of sealing-ring dovetail and O before this, when the distortion of this part is not enough to sealing, piping gas will enter room, selfsealings chamber, under the effect of piping gaseous tension, dovetail part is close to connection core pipe and is reached secondary seal, and sealing effect is better.
The utility model powder feeding pipes dedicated compensator, described sealing-ring is rubber circle.
Sealing-ring adopts import high temperature resistant silicon sizing material and advanced moulding process, the mold cure high by precision and the compound Jiao Quan that becomes, has excellent heat-resisting, wear-resisting and stopping property.
In sum, the beneficial effects of the utility model are: loop expansion pipe is heat-resisting, wear-resisting, sealing property is better.
Below in conjunction with accompanying drawing, the utility model powder feeding pipes dedicated compensator is described further.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is structural representation under the utility model sealing-ring normality.
Fig. 4 is structural representation under the utility model sealing-ring working order.
Embodiment
As Figure 1-Figure 2, the utility model powder feeding pipes dedicated compensator, comprise core pipe 1, tongued and grooved flanges 2, adjusting sleeve 3, housing 4, middle flange 5, sealing-ring 6, pull bar 7, baffle plate 10 and block 13, housing 4 has groove, the sealing-ring 6 being arranged in groove is enclosed within core pipe 1, sealing-ring 6 both sides are provided with adjusting sleeve 3, the two ends of adjusting sleeve 3 are separately installed with tongued and grooved flanges 2, middle flange 5 is welded on housing 4, tongued and grooved flanges 2 and middle flange 5 are connected by pull bar 7, and it is fastening by nut 8, baffle plate 10 is connected with tongued and grooved flanges 2 by bolt 11, block 13 is welded on core pipe 1. spring pad 9 is enclosed within pull bar 7 and between nut 8 and tongued and grooved flanges 2.
The regulate process of the utility model sealing-ring and core pipe is: is first arranged on by sealing-ring in the groove on housing and is enclosed within core pipe, again by adjusting sleeve press seal circle, the two ends of adjusting sleeve are fixed by tongued and grooved flanges, pull bar through middle flange connects the tongued and grooved flanges at adjusting sleeve two ends, and tongued and grooved flanges can be adjusted by adjustment pull bar, and then drive the fastening of adjusting sleeve and sealing-ring, thus the convenient sealing-gap adjusting sealing-ring and core pipe.
As Figure 3-Figure 4, sealing-ring 6 normality lower section is in " mountain " font. When sealing-ring 6 works, forming sealing by the distortion extruding of the distortion of rubber circle dovetail and O before this, when the distortion of this part is not enough to sealing, piping gas will enter room, selfsealings chamber, under the effect of piping gaseous tension, dovetail part is close to connection core pipe and is reached secondary seal.
The utility model compensates the axial displacement of pipeline by the relatively sliding of sealing-ring and core pipe, and carrys out the little angular travel of compensate for slower with the distortion of sealing-ring. Sealing-ring adopts import high temperature resistant silicon sizing material and advanced moulding process, the mold cure high by precision and the compound Jiao Quan that becomes, has excellent heat-resisting and wear resistance and stopping property. Whether it is in and compensates kinestate or stationary state, do not produce outer leakage.
The utility model does not do concrete explanation, all adopts prior art.
Above-described embodiment is only preferred implementation of the present utility model be described; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that the utility model claim book is determined.
