Direct media without thrust compensator
ZTWB direct media without thrust compensator: it is composed of reducer, inner sleeve, seal seat outer sleeve, flexible graphite packing, nuts and bolts. The advent of ztwb DC medium thrust free compensator is undoubtedly a breakthrough of thermal pipeline compensator products. It not only opens up a new field for the production of compensator, but more importantly, it not only solves the fatal weakness of working medium thrust in the pipeline, but also solves the disadvantages of excessive stress concentration and large medium resistance of bypass tube thrust free compensator.
Performance of direct media without thrust compensator
Using Pascal theory in fluid mechanics, it skillfully uses a dense annular steam chamber in the design structure. The steam chamber has two annular pressure surfaces respectively, one is the fixed end face of the steam chamber, and the other is the annular surface of the shoulder of the expansion pipe sealed in the steam chamber, which is movable with the expansion pipe. The area of the movable annular pressure surface is exactly equal to the cross-sectional area of the expansion pipe. When the compensator works, under the action of medium pressure, the pressure on the annular surface is equal to that of the cross-sectional area of the expansion pipe, but the direction is opposite, so the two pressures cancel each other. The selected sealing packing is flexible graphite, and the grades adopted are nuclear grade and industrial precision grade respectively. Some antioxidant components are added in the compensator packing to delay the oxidation time of the packing, so that the sealing performance of ztwb DC medium thrust free compensator is greatly improved compared with that of ordinary compensator.

Direct media without thrust compensator advantage
1. Reasonable design, compact structure and convenient installation.
2. No internal pressure thrust or blind plate force is generated, with large compensation capacity and low investment cost.
3. Wear resistant hard and smooth protective coating technology is adopted on the surface of the telescopic core pipe to improve the wear and corrosion resistance and greatly reduce the axial movement resistance of the telescopic core pipe.
4. flexible graphite composite sealing material with good resilience, high temperature resistance, corrosion resistance and aging resistance is adopted. It has enough sealing surface length and advanced sealing technology to ensure long-term and reliable sealing of products.
5. Guide bearing pads are set between the inner and outer sleeves at both ends, which can bear the lateral force of the pipeline and improve the positioning, guiding performance and working stability of the inner sleeve.
6. Reliable operation, high safety performance and long service life, up to more than 30 years.
7. It is convenient to maintain. In case of leakage of a few compensators, it can be stopped by slightly tightening the gland bolts or filling the sealing packing under the condition of non-stop production
Direct media without thrust compensator application
Thrust free compensator can be widely used in chemical industry, electric power, metallurgy, heat supply, temperature supply oil, acid and alkali, liquid, gas and water pipelines. It is the current pipeline expander. At the same time, it is convenient for pipeline design, installation and construction, and saves a lot of money (more than 60% can be saved only by fixing the support).
