Y-type strainer is an indispensable strainering device for the pipeline system conveying medium. Y-type strainer is usually installed at the inlet of pressure reducing valve, pressure relief valve, constant water level valve or other equipment to remove impurities in the medium and protect the normal use of valves and equipment. Y-type strainer has the characteristics of advanced structure, low resistance and convenient sewage discharge. The applicable media of Y-type strainer can be water, oil and gas. Generally, the water supply network is 18 – 30 mesh, the ventilation network is 10 – 100 mesh, and the oil supply network is 100 – 480 mesh. Basket strainer is mainly composed of connecting pipe, main pipe, strainer blue, flange, flange cover and fasteners. When the liquid enters the strainer blue through the main pipe, the solid impurity particles are blocked in the strainer blue, and the clean fluid is discharged from the strainer outlet through the strainer blue.
Working principle of Y-type strainer
Y-type strainer is a small equipment for removing a small amount of solid particles in the liquid, which can protect the normal operation of the equipment. When the fluid enters the strainer cartridge equipped with a certain specification of strainer screen, its impurities are blocked, and the clean filtrate is discharged from the strainer outlet. When it needs to be cleaned, just take out the removable strainer cartridge and reload it after treatment. Therefore, it is very convenient for use and maintenance. Y-type strainer, also known as decontaminator and strainer valve, is an indispensable device for the pipeline system conveying media. Its function is to strainer the mechanical impurities in the media, and can strainer the rust, sand and a small amount of solid particles in the sewage, so as to protect the accessories on the equipment pipeline from wear and blockage, and protect the normal operation of the equipment. The Y-shaped strainer is Y-shaped. One end is used to pass water and other fluids, and the other end is used to precipitate wastes and impurities. It is usually installed at the inlet of pressure reducing valve, pressure relief valve, constant level valve or other equipment. Its function is to remove impurities in the water and protect the normal operation of valves and equipment. The water to be treated by the strainer enters the body from the inlet, Impurities in the water are deposited on the stainless steel strainer screen, resulting in differential pressure. The pressure difference at the inlet and outlet is monitored through the pressure difference switch. When the pressure difference reaches the set value, the electric controller sends a signal to the hydraulic control valve and drive the motor, causing the following actions: the motor drives the brush to rotate to clean the strainer element, and the control valve is opened for sewage discharge. The whole cleaning process only lasts for tens of seconds. When the cleaning is completed, close the control valve and the motor stops rotating, The system returns to its initial state and starts the next strainering process. After the equipment is installed, the technicians shall conduct commissioning, set the filtration time and cleaning conversion time, the water to be treated enters the body from the water inlet, and the strainer starts to work normally.
Classification of Y-type strainers
1. The air strainer makes the polluted air clean to the state required by production and life, that is, to make the air reach a certain cleanliness.
2. The liquid strainer makes the contaminated liquid clean to the state required by production and life, that is, to make the liquid reach a certain cleanliness.
3. The network strainer blocks junk information through setting, so that the information on the computer screen meets the requirements as much as possible. The same absorption principle separates light of different colors
4. Light strainer to absorb some unnecessary light. The above should be a mesh strainer. In fact, there are many kinds of strainers, such as laminated strainer, sand strainer, carbon strainer, etc. the main principle is to use the pore diameter of the strainer medium to intercept substances smaller than the pore diameter of the medium. Of course, some strainer media also have special effects such as adsorption. Most strainer backwashing is not so troublesome. As long as clean water is introduced into the medium in the backwashing strainer from one end of the strainered water, a good backwashing effect can be achieved. This type of valve shall be installed horizontally in the pipeline.
Installation of Y-type strainer
Steam or gas pipeline: the strainer screen faces the horizontal direction;
Liquid pipeline: the strainer screen is installed downward;
Vertical installation: according to the strainer installation direction.
Product application of Y-type strainer
As an indispensable high-efficiency filtration equipment in purification equipment engineering, y-type strainer has played a great role in the treatment of domestic wastewater and industrial wastewater. It is now favored by virtue of its advantages in design and application. The application of Y-type strainer in various industries has effectively treated a large number of domestic and industrial sewage, effectively reused valuable water resources and saved a lot of water resources. The advantages of Y-type strainer in operation include full automation, maintenance free, large strainering area, high strainer efficiency, long service life, stainless steel material, optional strainering accuracy and complete specifications. Compared with other filtration equipment, it is one of the most effective equipment in reclaimed water reuse project. Moreover, the water quality treated by Y-type strainer not only meets the national discharge standard, but also realizes the purpose of reuse and recycling.
China Y-type strainer manufacturer www.sfutube.com supplies Y-type strainer for industrial use, in kinds of materials such as carbon steel, stainless steel, alloy steel, etc.
