Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a sealed electronic push-pull valve, including valve body 1, the inside fixed mounting of valve body 1 has division board 2, the inside of valve body 1 is provided with holds chamber 3 and medium passageway 4 and divide into two with both equal through division board 2, the one end fixed mounting of valve body 1 has two electric actuator 5, the equal fixed mounting of output shaft of every electric actuator 5 has valve plate 6 and drives valve plate 6 and remove and stop holding between chamber 3 and medium passageway 4, the equal fixed mounting in both sides of division board 2, one side of two valve plates 6 all is located between corresponding extension board I7 down and the relative one side of last baffle I8, the equal fixed mounting in both sides of valve body 1 inner wall has extension board II 9 down and last baffle II 10, the opposite side of two valve bodies 1 all is located between corresponding extension board II 9 down and the relative one side of last baffle II 10.

In this embodiment, shelter from medium passageway 4 through valve plate 6, thereby play the effect of blocking the medium, the removal of valve plate 6 needs to drive through electric actuator 5, electric actuator 5 drives valve plate 6 and removes between medium passageway 4 and holding chamber 3, the opening and shutting of electronic push-pull valve has been realized, when valve plate 6 has the removal in medium passageway 4, valve plate 6 is always between lower extension board I7 and last baffle I8, remove between lower extension board II 9 and last baffle II 10 this moment, when valve plate 6 is located medium passageway 4's inside completely, cooperation through these structures can form a seal structure, can effectually prevent that the medium from revealing, and the simple structure of reinforcing leakproofness, do not need additionally to increase electric mechanism and can accomplish, practicality and use value are high.

Specifically, the electric actuator 5 is an electro-hydraulic push rod or an actuator.

In this embodiment, the valve plate 6 can be driven to reciprocate in the linear direction by the electro-hydraulic push rod or the actuator.

Specifically, overhead gage I8 is located down the top and the slope setting of extension board I7, and overhead gage II 10 is located down the top and the slope setting of extension board II 9.

In this embodiment, when valve plate 6 entered into the inside that holds chamber 3, medium channel 4 was opened this moment, and the medium can pass through medium channel 4, and it is not smooth to cause the valve to remove on avoiding the medium to enter into lower support plate I7 and lower support plate II 9, consequently carries out the slope design with overhead gage I8 and overhead gage II 10, can block the medium, can guarantee that valve plate 6 can move smoothly in the inside of valve body 1.
