Strainer

Strainer a kind of indispensable device, usually mounted on the pressure reducing valve, relief valve, water valve or other device of the inlet side, the medium used to remove the impurities, to protect the valve and the normal use of equipment. When the fluid is placed into a certain specification of strainer cartridge, the impurity is blocked, and clean the filtrate by strainer outlet, when need to wash, just remove the removable cartridge, after processing to reload the can, therefore, use maintenance is very convenient.
Strainer by simplified part, stainless steel mesh, blowdown, transmission device and electric control parts. Strainer work, to strainer water from the nozzle into the, flows through the strainer, through exports into the user required to pipeline process cycle, the acrobatic trapped inside the strainer particles in the water.
As a continuous cycle, were trapped and particles is increasing, filtration speed slower and slower, and imports of sewage is still flowing into, china strainer hole will be more and more small, the pressure difference between inlet and outlet, when poor magnanimous reached set value, differential pressure transmitter will be routed to the controller, the control system startup drive motor through a transmission component drive shaft rotation, open the outlet at the same time, by the drainage outlet discharge, after when the screen is clean, to minimize the pressure difference value, the system returns to the original strainer, normal operation of system.
Strainer by shell, multiple strainer, backwash, and differential pressure controller and other components. Shell within the diaphragm plate inside cavity is divided into upper and lower two cavity, the cavity is equipped with multiple strainer core, make full use of the strainer space, so significantly narrow the volume of the strainer, are installed in the inferior vena recoil wash suction cups. Work, muddy fluid through the inlet into the inferior vena strainer, and a baffle hole into the core of internal chamber,china butterfly valve. Is greater than the strainering core crack impurities trapped, net liquid chamber through the gap to, finally sent out from exports. Wedge strainer strainer uses the high strength, through differential pressure control, timing control automatic cleaning strainer. Accumulation of impurities in the strainer in the strainer surface caused by pressure difference increases to the set value of import and export, or when the timer reaches preset time, the electric control box signal, drive back flush.
When backwash suction dish with the strainer inlet is pair, drain valve is opened, the system pressure drainage, chuck and relative pressure is below the strainer strainer inside of the emergence of a negative pressure zone of the lateral pressure, forcing some circulating water from strainer lateral flow into the china check valve, the impurity particles on the adsorption on the inner wall of the strainer element inside with flow into disc and is discharged from the drain valve.
Specially designed mesh makes the strainer inside the injection effect, any impurity will be washed away from the smooth inner wall. When the strainer differential pressure back to normal import and export or timer setting time is over, the entire process,, the material does not block the backwashing water consumption less, realizes the continuous, automatic production.
