Description
Technical field
The utility model relates to valve technology field, specifically, relates to a kind of two position three way directional control valve.
Background technique
Selector valve is also control unit, after receiving (electricity/gas/machinery) signal, selector valve can change the direction of air-flow, thus promotes the to-and-fro motion of cylinder piston, usually uses two position three way directional control valve that coal gas of high temperature, rock gas or air are commutated in industrial furnace pipeline.But at present, the two position three way directional control valve on market is easily out of shape and poor sealing performance under worst hot case.
So, develop a kind of two position three way directional control valve that also can obtain high-leakage grade under worst hot case medium, just become the problem that Professional visitors needs solution badly.
Model utility content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of two position three way directional control valve, structural stability, good seal performance.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of two position three way directional control valve, comprise valve body, described valve inner is split three air chambers arranged in Pin form by dividing plate, described air chamber comprises the air chamber one that is positioned at described valve body lower portion and the air chamber two being positioned at valve body top and air chamber three, described air chamber one, the outside of air chamber two and air chamber three is all connected with external pipe by flanged (FLGD) interface, separate completely between described air chamber two and described air chamber three, described air chamber one is communicated with interface with being provided with between described air chamber two and described air chamber three, the valve plate that described connection jointing is provided with valve seat and coordinates with described valve seat, wherein, described valve plate is positioned at described air chamber one and is connected with the pneumatic actuator being vertically mounted on described body top by valve rod, described valve plate is connected with the sealing pair of described valve seat by the positive round conical surface, and, described valve body, described valve plate, described valve seat and described pneumatic actuator all adopt SUS304 stainless steel.
Further, the quantity of described pneumatic actuator is 2.
The beneficial effects of the utility model: this device is by adopting SUS304 stainless steel, and the sealing pair of the positive round conical surface is adopted at valve plate and valve seat joint, structural stability, good seal performance, also high-leakage grade can be obtained under worst hot case medium, thus the usage requirement met under worst hot case ambient condition, and then this two position three way directional control valve is made to have more wide market prospects.
