Today, we will talk about a common valve in the pipeline. This valve has a very important role. It is a Y strainer.
What is the function of pipe strainers?
The
Y strainer is an indispensable device for conveying medium pipeline system. It is usually installed in the pressure relief valve, pressure relief valve, constant water valve or other equipment inlet end. It is used to remove impurities in the medium, in order to protect the normal use of valves and equipment.
The Y strainer is an indispensable device (valve) on the transmission medium pipeline. It is usually installed in the safety valve, pressure relief valve, pressure relief valve, trap valve, constant water level valve, cut-off valve and other front-end. The strainer consists of a cylinder, stainless steel strainer screen, sewage discharge part, transmission device and electrical control part (some models do not need to be configured). After the media is through the strainer tube, its impurities are blocked. When the strainer needs to be cleaned, the strainer device, strainer after cleaning treatment can be reloaded as long as the detachable strainer cartridge is removed. Therefore, the use and maintenance are very convenient. The following describes the working principle of Y strainers: The Y strainer is a small equipment to remove solids in the liquid, which can protect the normal operation and operation of the compressor, pump and other equipment and instruments, so as to stabilize the process and ensure safety. In addition, the Y strainer is of great significance to improving product quality.
The Y strainer has the advantages of compact structure, large filtration capacity, small pressure loss, wide application range, convenient maintenance, etc. Its main applicable materials are chemical, petrochemical production of weak corrosive materials, such as water, oil, ammonia, hydrocarbons and so on.
Y strainers can remove solid impurities in the pipeline, which can be said to be one of the biggest roles of Y strainers. Y strainers are applicable to a wide range of applications.
Correct installation methods of Y strainers
A Y strainer is installed at the inlet of the equipment to remove impurities in the medium to protect the valve. The correct method of installation is to mount horizontally or vertically downwards.
1. The working principle
The Y strainer is an indispensable strainer device in the pipeline system of conveying fluid medium. The Y strainer is usually installed in the pressure relief valve, pressure relief valve, cut-off valve (such as the inlet end of the indoor heating pipeline) or other equipment. It is used to remove impurities in the medium to protect the normal use of the valve and equipment. The Y strainer has advanced structure, low resistance and convenient sewage discharge. The Y strainer is mainly composed of pipes, strainer screens, flanges and fasteners. When the liquid enters the strainer basket, the solid impurity particles are blocked in the strainer blue, and the clean fluid is discharged through the strainer basket and the strainer outlet. The reason why the strainer is cylindrical basket shape is to increase its strength, which is stronger than a single layer of net, and the flange cover at the bottom of the shaped interface can be unscrewed to remove the particles and impurities deposited in the strainer basket regularly.
2. The installation methods
Before the installation of strainers, we need to carefully clean the threaded connection surface of all pipelines. The use of pipeline sealant or teflon belt (PTFE) needs the appropriate amount. End threads are not treated to prevent sealants or teflon tapes from entering the piping system. Strainers can be installed horizontally or vertically downwards.
