Abstract
The utility model relates to a sealed balanced pipe compensator, mainly comprising an outer sleeve pipe, an expansion pipe, a fixed ring, a spring propeller, sealing filling, a sealing ring and a pressure-releasing barn positioned in the outer sleeve pipe and the on the end of the expansion pipe, wherein, the fixed ring, the spring propeller, the sealing filling and the sealing ring are in turn arranged between the outer sleeve pipe and the expansion pipe. Because the utility model can inject the sealing filling through the injection hole which corresponds to the filling on an outer sleeve pipe, and a pressure-releasing hole is arranged on the side wall of the pressure-releasing barn, the utility model has good sealing effect, the leakage doesn't easily happen, the thrust force of a blind plate is small, and particularly the leakage slaking can be conveniently carried out in the state of no production halts and having the pressure.
Description
The utility model relates to a kind of pipeline causes displacement because of expanding with heat and contract with cold compensation device, particularly a kind of sealing and balancing formula pipeline compensator.
Usually, all kinds of compensation devices that adopt in the pipeline, in use all in various degree have a leakage phenomenon, it is CN2050918U that the utility model patent communique once disclosed a kind of notification number, name is called " sealed pipe expansion bend " patent.It is mainly by outer sleeve, telescopic pipe, and the spring propulsion between outer sleeve and telescopic pipe, active ring, retainer ring and adjusting bolt constitute, it is to make pipeline be in sealing state by spring propulsion and self pressure action of medium, to realize its sealing without leakage, but because spring propulsion is limit by the position, according to calculating, the required impacting force of filler that even whole springs are pressed and the total pressure of generation also is nowhere near, therefore, this device still has leakage phenomenon, rear filler-changeable or adjust particularly need stop production when line transportation medium compensation device occur to leak, during again owing to the line transportation medium, the blind plate thrust by pressure medium produces can make support of pipelines produce corresponding power, so when support was insecure, phenomenon of rupture very easily collapsed.
The purpose of this utility model is to provide a kind of sealing and balancing formula pipeline compensator, and not only good sealing effect, difficult leakage but also blind plate thrust are less for it, particularly can carry out leakage eliminating easily under the band pressure condition that do not stop production.
Its concrete solution is: be disposed with retaining ring between outer sleeve and the telescopic pipe, spring propulsion, stuffing box packing and seal ring, spring propulsion is made of 9-40 springs, be provided with 3-12 injection orifices with the outer sleeve of stuffing box packing institute corresponding position, injection orifice is provided with the injection pressure head, the stuffing box packing that is positioned at seal ring and spring propulsion end adopt be graphite packing and heatproof seal gease it both can play the blind effect, can reduce frictional force between telescopic pipe and the outer sleeve again and lubricate, the middle part can be injected stuffing box packing by injection orifice and carry out leakage eliminating for can annotate the formula stuffing box packing under the band pressure condition that do not stop production.The flexible pipe end that is positioned at outer sleeve is provided with a pressure release storehouse, is connected on the sidewall in pressure release storehouse of flexible pipe end and is evenly equipped with 3-12 relief holes.
The utility model adopts and can annotate the formula stuffing box packing and be provided with the injection orifice that is used for the pressure injection stuffing box packing, under the injection pressure effect because of its good flowability and high elasticity, and can reach good sealing effect, form a complete sealing loop, increased the elasticity of sealing configuration inside, the increase of inner expanding force also improves leakage prevention capability greatly, if compensator is normal in service the leakage, also can not lower the temperature, the band that do not reduce pressure is pressed under the working state and is carried out leakage eliminating, thereby it is difficult thoroughly to have solved maintenance, the leak-stopping difficulty, change the problem of filler difficulty, owing to adopt the heatproof seal gease, so it both can reach the effect of blind, can reduce frictional force lubricate between telescopic pipe and the outer sleeve again.Again owing to be provided with the pressure release storehouse and the pressure release storehouse is provided with relief hole, when so it both can make telescopic pipe axial displacement, reduce deviation, the vortex reverse direction flow pressure release storehouse that blind plate is produced, reduce thrust to blind plate, thereby balance to the load thrust of support of pipelines, pressure medium is acted on the sealed picture, strengthened sealing.Real is a kind of sealing and balancing formula pipeline compensator that is widely used in each pipeline such as water delivery, oil transportation, gas transmission.
In conjunction with the accompanying drawings the utility model is described in detail below by embodiment:
Accompanying drawing is the utility model structural representation.
In the present embodiment, pressure release storehouse sidewall (11) is welded on an end of telescopic pipe (1), outer sleeve (2) is one by connecting ring (12) with fixedlying connected pipe (13) weldering, capping (14) is by being bolted on the outer sleeve, spring propulsion (5) mainly is made up of 24 springs, spring adjusting screw (4) serves as to rely on to be supported on the retaining ring (3) with retaining ring (3), and what be provided with between spring propulsion (5) and the seal ring (9) is stuffing box packing.Wherein, the BM filler (8) that adopt at the middle part for annotating, both sides adopt for graphite packing and modified graphite and high temperature grease be main heatproof seal gease (6), be provided with 3 injection orifices (7) with the pairing outer sleeve of BM filler (8) that can annotate, injection orifice (7) is provided with can be annotated pressure head (17), telescopic pipe (1), pressure release storehouse sidewall (11), outer sleeve (2) and the formed space of seal ring (9) and constitute a pressure release storehouse (10), is evenly equipped with 6 relief holes (16) on the sidewall of pressure release storehouse.
It is right to use, can be connected with pipeline by the flange (15) at two ends, when medium passes through, the eddy current reverse direction flow pressure release storehouse sidewall (11) that medium is produced by blind plate in the pipe, enter the pressure release storehouse by relief hole (16), make it both reduce thrust to blind plate, balance to the weight bearing power of support, pressure medium also can act directly on the seal ring (9), strengthened the sealing of Sealing, can adjust the impacting force of spring propulsion (5) by adjusting screw (4), can annotate stuffing box packing and can pass through injection orifice (7) injection Sealing.
Claims (3)
1, a kind of sealing and balancing formula pipeline compensator, be disposed with retaining ring (3), spring propulsion (5), stuffing box packing (8) and seal ring (9) between its outer sleeve and the telescopic pipe, it is characterized in that being provided with injection orifice (7) with the outer sleeve of stuffing box packing institute corresponding position, injection orifice (7) is provided with injection pressure head (17).Be positioned at the flexible pipe end of outer sleeve (2) and be provided with a pressure release storehouse, be connected on the pressure release storehouse sidewall (11) of flexible pipe end and be evenly equipped with relief hole.
