Liquid filter is an indispensable device on the transmission medium pipeline. It is usually installed at the inlet of pressure reducing valve, pressure relief valve, constant water level valve or other equipment to eliminate impurities in the medium and protect the normal use of valves and equipment. When the fluid enters the filter cartridge with a certain specification of filter screen, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When cleaning is required, just take out the removable filter cartridge and reload it after treatment.
The working principle of liquid bag filter is pressure filtration. The complete bag filter consists of three parts: liquid bag filter container, supporting net basket and liquid filter bag. The liquid to be filtered is injected from the top or side of the bag filter and directly enters the liquid filter bag to make the liquid filter bag evenly distributed without the negative effect of turbulence; The particles filtered by the bag filter are retained in the liquid filter bag for easy replacement. The liquid bag filter comprises a single bag filter and a multi bag filter; The main products of Guangdong Longtian filter equipment factory include filter, bag filter, precision security filter, stainless steel precision filter, PP plastic filter, liquid filter, liquid filter bag, nylon filter bag, food and beverage filter bag, electrophoretic degreasing filter bag, Chemical electronic ink filter bag, coating filter bag, filter bag, filter element, filter screen.
Filters have been used in a variety of applications, including hydraulic systems and engine lubrication systems. In these types of systems, the filter is changed regularly. One type of filtration system used includes a cup cartridge filter. Cup cartridge filters usually include reusable cups and fixed replaceable filter elements (cartridge filters). The cup-shaped cartridge filter is usually installed on the filter head, wherein the liquid to be purified enters the cup through the filter head, passes through the replaceable filter element, goes outside the cup, and returns to the filter head. After a period of use, remove the cup filter cartridge from the filter head, and remove the replaceable filter cartridge from the reusable cup. Discard the old cartridge filter and replace it with a new cartridge filter. The new cartridge filter is operably installed in a reusable cup to provide a new cup filter. The new cup-shaped cartridge filter containing a new cartridge filter is then installed on the filter head.
A liquid filter structure in which a leak proof check valve assembly is provided. Various alternatives that can be used to implement different principles related to leak proof check valve assemblies are disclosed and examples are shown. For the structure shown, the leak proof check valve assembly is so constructed that the valve assembly will allow liquid to flow through the valve head only if the filter element is properly placed in the filter assembly using the filter head. Preferred components, assembly and use methods are also provided. Various specific features for obtaining the desired results are shown. There may be several alternatives. For the components to obtain certain advantages according to the invention, it is not necessary to adopt all the preferred features characterized by the invention for the components.
