The operation principle of above-mentioned one-way valve member in dual flow filter is as described below, can understand with reference to figure 8-1,8-2, and Fig. 8-1 is the flow path figure of fluid from left to right in Fig. 3 during dual flow filter; Fig. 8-2 is the flow path figure of fluid right-to-left in Fig. 3 during dual flow filter.
When fluid flows into from left side, right side is flowed out:
Fluid pressure action is in the outlet valve 40 in left side, and outlet valve 40 is close to and the outlet 22 of baffle plate 20 on the left of capping, and outlet valve 40 is in closed condition; The import 21 of baffle plate 20 on the left of direction of flow, fluid pressure action is in the umbrella imported valve 10 in left side, and imported valve 10 distortion is turned up, and be in opening, then fluid enters filter interior through the import 21 of left side baffle plate 20;
Fluid, after the filter screen 50 in filter filters, flows to the one-way valve member on right side;
Fluid pressure action is in right side imported valve 10, and the imported valve 10 of umbrella is out of shape and is close to the import 21 of right-hand apron 20, thus covers this import 21, and imported valve 10 is closed; The outlet 22 of direction of flow right-hand apron 20 surrounding, fluid pressure action, in outlet valve 40, makes the outlet 22 that it departs from right-hand apron 20, then the outlet valve 40 on right side is opened, produce gap between outlet valve 40 and baffle plate 20, fluid is through this gap outflow filter.
When fluid enter from right side, left side flow out time, flow path and above-mentioned just the opposite, as shown in Fig. 8-2, repeats no more herein.
As mentioned above, imported valve 10 and outlet valve 40 are elastomeric element, and along with the change of direction of flow, under fluid pressure action, elastomeric element by self morph capping or depart from corresponding import 21 or outlet 22, thus realize the keying of valve.The valve mechanism combined with spring in background technology and catch is compared, and the one-way valve member of this structure has following advantages:
