Description
Technical field
This utility model belongs to valve technology field, especially relates to a kind of filter check valve.
Background technology
nullValve is the control parts in fluid delivery system，There is cut-off、Regulation、Water conservancy diversion、Prevent adverse current、Voltage stabilizing、The functions such as shunting or overflow pressure relief，And valve has and is widely applied very much，In recent years，Owing to people are for water resource、Oil、The demand of natural gas sharply increases，The use of conveyance conduit gets more and more，Required structure also becomes increasingly complex，Traditional valve is can not meet far away the demand of conveyance conduit，And valve the most usually can run into the phenomenon of refluence，For avoiding the generation of this situation，In use，Common valve can be replaced with check-valves，Can effectively prevent the fluid in pipeline from situation about flowing backwards occurring，But usually can there is a lot of impurity in the fluid carried，When fluid carries，Impurity in fluid can be accumulated in valve pipe，Owing to can not in time impurity be derived，Too much impurity can cause the blocking of pipeline，Affect the normal use of valve.
Utility model content
In view of this, this utility model is directed to a kind of filter check valve, so that valve is possible to prevent the fluid countercurrent current in pipeline, and can be sifted out by the impurity in fluid, by external for impurity delivery valve when impurity is too much, does not interferes with the normal use of valve body.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that
nullA kind of filter check valve，Including valve body、Flexible Connector and valve port，Described valve body two ends are provided with water inlet and outlet，Filter chamber and stem guiding chamber it is provided with in described valve body，It is provided with filter element in described filter chamber，Described filter element includes cartridge filter，Described cartridge filter is provided with aperture，Described cartridge filter is near described water inlet one end hollow out，The described cartridge filter other end is provided with baffle plate，Described filter chamber exit is provided with filtering cover，Described filtering cover and described valve body pass through Flange joint，Described stem guiding intracavity portion is provided with valve rod and seal member，Described valve rod and described seal member are connected by described Flexible Connector，Described valve port sidewall is provided with protrusion，Described seal member includes spool，It is formed around sealing ring bottom described spool，Described spool bottom center is provided with sealing gasket，Described spool contacts with described protrusion，Described stem guiding top of chamber is provided with valve gap，Described valve gap is connected with described valve flange.
Further, described sealing ring is rubber ring；
Further, described sealing gasket is hemispherical rubber blanket；
Further, described baffle plate is provided with handle；
Further, described Flexible Connector is spring.
Relative to prior art, a kind of filter check valve described in the utility model has the advantage that
A kind of filter check valve described in the utility model, contaminant filter in fluid can be fallen and centralized collection by filter element, ensure the degree of purity by the fluid of valve, the impurity filtered out can delivery valve external, the situation not having valve blockage occurs, the spool of seal member uses full rubber to make, sealing effectiveness is good, can effectively prevent the generation of liquid refluence situation, have simple in construction, sealing effectiveness is good, practical feature.
