Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Below with reference to Fig. 1 to Fig. 4, the utility model is described.
The synchronous auto-compensating switching valve of a kind of duplex, comprise a pair safety valve 1, import switching valve 2 and outlet switching valve 3, described import switching valve 2 comprises the import valve body 2a that has an import 21 and two outlets 22, described outlet switching valve 3 comprises the outlet valve body 3a that has an outlet and two imports, the import of the safety valve 1 described in a pair exports 22 with two of described import valve body 2a respectively and is connected, the outlet of the safety valve 1 described in a pair is connected with two entrances of described outlet valve body 3a respectively, import switching valve 2 also has the valve seat 8 being separately positioned on import valve body 2a two outlet 22 places, flap 4 and the valve rod 5 be connected with flap 4, valve rod 5 drives flap 4 alternately to valve seat 8 opening and closing.Outlet switching valve 3 also has identical structure, no longer repeats at this.
Described import switching valve 2, outlet switching valve 3 are connected with the interlock 6 controlling its synchronous interaction, for driving this switching valve to carry out switching action, this interlock 6 is identical with interlock disclosed in " one imports and exports double linkage changeover valve " described in background technique.
The sidewall of flap 4 is arranged a circle fluting 41, make the flap 4 of fluting 41 both sides to centre, elastic strain can occur, flap 4 moves to when offseting with valve seat 8 can form elastic packing, improves sealability.
Import switching valve 2 and outlet switching valve 3 also have the guide sleeve 7 in one of them outlet port of one of them outlet and the outlet valve body 3a being separately positioned on described import valve body 2a, described guide sleeve 7 is slidably matched with corresponding valve rod 5, because valve rod 5 is longer, can prevent valve rod 5 from the volley unusual fluctuation occurring, add the accuracy of location, the work that makes it is more stable, reliable.
Import switching valve 2 and the valve seat 8 exported away from guide sleeve in it 7 in switching valve 3 all can, along valve rod 5 moving direction generation elastic movement, make this valve seat 8 also can form elastic packing, coordinate flap 4 to form double elastic sealing, reach better sealing effect.The elastic movement of valve seat 8 is realized by following structure, described two flap dorsad 4 sides away from the valve seat 8 of guide sleeve 7 are respectively equipped with spring 9, described spring 9 one end and import valve body 2a or export valve body 3a and offset, the other end offsets with corresponding valve seat 8, also can arrange the cavity of putting spring 9 at valve seat 8 simultaneously.
Valve seat 8 and import valve body 2a and be equipped with 0 shape seal ring 10,0 shape seal ring 10 between valve seat 8 and outlet valve body 3a and reveal for preventing, raising sealability.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improvement of above-mentioned hypothesis and modification also should be considered as protection domain of the present utility model.
