Sleeve type compensator

Sleeve type compensator mobile phone

1. Overview
Huitong has been specializing in the design and production of directly buried corrugated expansion joints, external pressure corrugated expansion joints and sleeves for heating pipe networks since 2008. In the past 20 years, we have provided tens of thousands of products to hundreds of heating companies. The corrugated expansion joints and sleeve compensators designed and produced have the characteristics of large compensation capacity, small thrust, and resistance to underground chloride ion corrosion. Its long life and product quality have been unanimously trusted and recognized by the majority of users. At the same time, we can provide customers with on-site guidance services for expansion joint pipeline installation upon customer request.
2. Materials
The sealing materials of sleeve compensators include packing products, polytetrafluoroethylene, rubber products, sealing oil and other special sealants.
3. Features
Material-sealed sleeve compensator is a contact seal. Elastic sealing material is filled between the outer sleeve and the core pipe. After the filler is compressed by axial force, it can Close to the surface of the core tube, the elastic deformation of the sealing material is used to compensate for the wear of the sealing surface and prevent the leakage of the medium. Currently, it has been developed from a single filler to a combination of uses, such as hard filler placed deep, soft filler near the gland or hard and soft filler. Put sealing oil in the middle. If leakage occurs, refill the oil to stop the leakage.
The mechanical seal sleeve compensator is composed of at least one pair of end faces perpendicular to the rotating axis. Under the action of fluid pressure and the external elastic force of the compensation mechanism, it keeps fit and slides relative to the other end face, thereby preventing the fluid from flowing. Leaked device. It is characterized by high geometric tolerance and matching accuracy requirements, no leakage, and avoids frequent damage caused by leakage of old compensators in the past.
4. Type
Buried sleeve compensator adopts advanced sealing structure and sealing materials. It is suitable for hot water, steam and grease media. Through the sliding movement of the sliding sleeve against the outer sleeve, it can achieve Compensation for thermal expansion. It has the characteristics of reasonable structure, safety and reliability, long service life, no leakage, convenient installation and maintenance, and wide application range. At the same time, it facilitates pipeline design and installation, and can reduce the installation of fixed brackets.
For the sleeve compensator, there are telescopic core tubes in both directions of the outer sleeve of the ordinary type. The compensation is twice that of the ordinary type, and it is used for two-way compensation, reducing the length of two ordinary types. Size and cost.
The sealed corrugated sleeve compensator (patented product) has a double insurance function. This product integrates a bellows-type compensator, which is equivalent to adding a mechanical seal outside the bellows compensator. Once there is a problem with the bellows, the compensator can still work normally. Reliable performance and improved bending resistance. Due to the lack of mechanical seal, the bellows inside the bellows is isolated from the outside world and protected from harmful substances, especially chloride ions, which makes the work of the bellows compensator more reliable. At the same time, the mechanical seal increases the guiding function of the movable end. Improve bending resistance.
Disposable sleeve compensators are used for preheating and expansion of directly buried pipelines and are welded at the two contact surfaces of the pipeline. The outer sleeve and the core pipe can no longer move relative to each other, and then are buried. It has the same service life as the pipeline. Features.
5. Scope of application
Sleeve type compensator can be widely used in pipeline networks such as chemical industry, petroleum, thermal power, metallurgy, urban central heating, etc., as well as trenches and elevated pipelines.
6. Use environment
Surface thermal spraying is used in conditions with a high degree of environmental medium corrosion.
Surface chromium plating is used when the corrosion degree of the environmental medium is medium and the operating temperature is higher than ℃.
Under conditions where the corrosion degree of the environmental medium is low and the operating temperature is lower than ℃, the surface should be galvanized.
