â… . Product Introduction
The Y-Style Tie Rod Expansion & Retraction Facility (YSTF), also known as the Y-type tie rod expansion filter, is an integrated equipment that combines the functions of a Y-type filter and an expansion joint. It is specifically designed for water supply and drainage systems in various scenarios, including civil buildings, multi-storey buildings, and industrial factories.
The core application purpose of this facility is to protect the safe and stable operation of key equipment in the pipeline system, thereby ensuring the smooth progress of production and operation. It is usually installed at the front end of critical equipment such as pressure relief valves, fixed water level valves, and other main process equipment. By filtering impurities in the medium and compensating for pipeline displacement, it can effectively prevent the damage, blockage, or failure of subsequent equipment caused by impurities or pipeline thermal expansion and contraction, providing a reliable guarantee for the safe production of the entire system.

-
Integrated Design, Compact Structure: The product integrates the filtering function of the Y-type filter and the expansion compensation function of the expansion joint into one, avoiding the complex pipeline connection caused by the separate installation of two devices. It has a compact structure, small occupied space, and simplifies the pipeline layout, which is convenient for installation and maintenance in limited space.
-
Excellent Filtration Performance: Equipped with high-quality stainless steel filter elements, the facility can effectively filter impurities such as particles, sediments, and debris in the water supply and drainage medium. The filter accuracy can be flexibly selected from 10 mesh to 500 mesh according to actual working conditions, ensuring that the medium entering the subsequent equipment is clean and free of impurities, and prolonging the service life of the equipment.
-
Reliable Expansion Compensation: With the built-in expansion joint structure, the facility can effectively absorb the axial, lateral, or angular displacement of the pipeline caused by temperature changes, pressure fluctuations, or foundation settlement. The tie rod design ensures the stability of the equipment during expansion and contraction, preventing excessive deformation or deviation of the pipeline, and reducing the stress on the pipeline and equipment connections.
-
Wide Material Adaptability: The shell of the facility can be made of carbon steel, stainless steel, and other materials, and the gasket can be selected from PTFE, metal winding, nitrile rubber, etc., according to the characteristics of the medium (such as corrosion, temperature, pressure) and working environment. This wide material selection range enables the product to adapt to various harsh working conditions, including corrosive mediums, high-temperature and high-pressure environments.
-
Stable Sealing Performance: The flange sealing surface adopts RF, M, FM and other common sealing forms, matching with high-quality gasket materials, which can achieve reliable sealing under different pressure levels (0.25-6.3MPa). It effectively prevents medium leakage, ensures the tightness of the pipeline system, and avoids environmental pollution or resource waste caused by leakage.
-
Strong Compatibility, Wide Application Range: The product covers a wide range of nominal diameters (DN15-DN500, i.e., 1/2′-20″) and is equipped with flange connection mode, which is compatible with most standard pipelines. It can be widely used in water supply and drainage systems of buildings, multi-storey buildings, factories, and other fields, meeting the needs of different scale and type of pipeline projects.
