The model utility content
In order to solve the problem of above-mentioned existence, the purpose of the utility model provides a kind of novel two position three-way valve.
To achieve these goals, the technological scheme below the utility model has adopted, specific as follows:
A kind of novel two position three-way valve; Comprise valve body, valve seat, two valve plates, two valve rods and two drive units, wherein said valve body is fixed on the valve seat, and said valve body is divided into first air chamber, second air chamber and the 3rd air chamber; Wherein first air chamber is positioned at an end of valve body; Second air chamber and the 3rd air chamber are positioned at the other end of valve body side by side, and said two drive units lay respectively at the both sides, top of valve body, and said drive unit is connected with an end of the valve rod that Vertical direction is provided with; Said valve plate is connected with the other end of valve rod, and drive unit moves through valve rod drive valve plate and realizes the folding of valve.
Preferably, said two valve plates lay respectively at the joint between first air chamber and second air chamber and first air chamber and the 3rd air chamber.
Preferably, the edge of said valve plate is corresponding with valve seat, is provided with seal ring between valve plate and the valve seat.
Preferably, the top of said valve body is provided with support, and said drive unit is sheathed on internal stent.
Preferably, said drive unit is provided with limiting board and near switch, saidly is located on the limiting board near switch.
Preferably, said drive unit adopts any one in pneumatic mode, the mode of surging and the electronic mode.
Preferably, an outside side of said first air chamber, second air chamber and the 3rd air chamber is equipped with flanged joint.
The utility model is through being divided into valve body first air chamber, second air chamber and the 3rd air chamber three air chambers altogether, and wherein first air chamber is positioned at an end of valve body, and second air chamber and the 3rd air chamber are positioned at the other end of valve body side by side; Employing makes the structure of the utility model become more simple the structural design that three air chamber collection are one, and volume is also more little; Inspection and maintenance is also more easy; Simultaneously between valve plate and valve seat, be provided with seal ring, effectively guaranteed the effect of valve seal, the drive unit of the utility model; Can be to adopt in pneumatic mode, the mode of surging and the electronic mode any one according to actual conditions; When valve body is connected with external pipe, realize connecting, connect to guarantee to seal good and stable through flange through flanged joint.
Description of drawings
