All welded filtering pneumatic valve filter disassembling method _ pneumatic components factory valve industry

All welded filtering pneumatic valve is a pneumatic valve which has the function of filter medium, it is the filter and aerodynamic body as a whole structure design, the filtering function and fluid control feature set in one; Due to the filter pneumatic valve adopts integral all-welded, makes the body will not have any leakage phenomenon appeared. Widely used in natural gas, water and other medium to medium cleanness in transmission has strict requirements on the pipeline. All welded filter working principle of the pneumatic valve, pneumatic valve in filtration open state, the pneumatic body fluid through hole inside the cavity, the fluid by its own set of filter for filtering, when the aerodynamic body 90 degrees clockwise, the filter type pneumatic valve closed, blocking the role of fluid medium in the pipeline. All pneumatic valve welding filter mesh disassembling methods: set in the wall of the valve body unicom tathagata flange and cleaning pipe connecting tubes, can open the tathagata flange cover and drainage tube, convenient clean screen pack, can also be set on the drainage tube electric or pneumatic valve, in order to achieve automatic flush filter. If the screen broken, open the tathagata flange cover can be replaced. （ See the dynamic figure) All welded filtering pneumatic valve working principle figure 1, filter mesh disassembling pneumatic valve in the closed state, through the relief valve, gradually release the pressure of filter pneumatic valve body until no pressure. After 2, filtering, there is no pressure in the pneumatic valve, pneumatic valve outlet opened slowly filtering. 3, the liquid pneumatic valve slowly remove dirt and impurity particles. Take out after 4, remove the bolts fixed filter filter full of particles and impurities. 5, the already clean/replace filter, install back to filter in pneumatic valve outlet, began to work properly.
