Compensator.
Background technology
Pipeline compensator mainly solves pipeline and expanded with heat and contract with cold caused by temperature change problem, eliminates pipeline internal stress,
Pipe network is set to keep good operating mode.At present, the compensation way of gas pipeline compensator mainly has three kinds of forms：First, mend naturally
Repay, second, metal bellows compensates, third, sleeve expansion joint compensates, the advantage and disadvantage of various compensation ways are as follows：
Natural compensation refers to the natural torsion shape using pipeline（It common are L-shaped or Z-shaped）Possessed flexibility, come real
The cold and hot compensation of existing pipeline, its advantage are：It is durable, bearing capacity is high；Shortcoming is：Space-consuming is larger, investment is big, compensation rate
It is small.
Metal bellows compensation is to set one section of metal bellows at spacing intervals on the straight section pipeline of gas pipeline,
Its advantage is：Occupy little space, it is air tight in its fatigue range；Shortcoming is：Bearing capacity is low, and service life is short.
Sleeve expansion joint is also known as material filling type compensator, and its operation principle is the size of compensator when pipeline expands with heat and contract with cold
Sleeve is relatively moved to absorb its expansion length, and advantage is：Compensation rate is big, occupies little space, bearing capacity height；Shortcoming is：
Need to regularly replace filler, otherwise easily leak, maintenance load is big.
Utility model content
The purpose of this utility model is to be directed to above-mentioned the deficiencies in the prior art, there is provided a kind of compensation ability is big, sealing
Can reliable, service life length aerial gas pipeline compensator.
To achieve the above object, the technical solution adopted in the utility model is：A kind of aerial gas pipeline compensator, including
Sleeve and the core cylinder in sleeve, closure is provided with being inserted between end and core cylinder for sleeve, is provided with the insertion end of core cylinder
Guide ring, the guide ring are provided with some balance pipes；In the cavity that sleeve and core cylinder, closure and core cylinder guide ring surround
Be used to compensating provided with airtight and watertight padding, positioned at airtight and watertight padding both sides the first elastic spring assembly of filler and second spring device, with
And for adjusting the regulator of spring pressure.
The utility model when in use, can operate to regulator, pass through the spring assembly of airtight and watertight padding both sides
The loosening of automatic compensation filler, makes filler reach required precompression, so as to reach sealing purpose.
Compared with existing pipeline compensator, the utility model have small volume, compensation ability it is big, it is easy for installation, sealing
The remarkable advantages such as dependable performance, service life are long, cost is low, especially suitable for the pipe network of long range straight-run, it can answer extensively
For industries such as electric power, urban heat supplying, petrochemical industries.
