Double-way transmission valve is generally used in building materials, metallurgy, mining, petrochemical, electric power, light industry and other industries, used for high pressure pneumatic transmission of cement, cement raw material, limestone, pulverized coal and other powder substances in the pipeline system, play the role of transmission direction, generally installed in the bifurcation of the pipeline.
design feature:
Double delivery valve, internal direction with rotating valve disc, by the pressure regulating device control of the sealing surface, the valve disc shape with the form, in the movement of the sealing surface attachment, ensure the sealing performance, the valve its structure is perfect, flexible, reliable, good air tightness, wear resistance, and delivery channel smooth, smooth, to ensure that the fluid flow. S is worm wheel transmission, D is electric transmission, and Y is electrohydraulic transmission.
operational principle:
The double transmission valve is mainly composed of left and right valve body, rotating valve disc, regulating device, sealing surface and positioning cam and other components. The manual wheel drives the worm wheel with the drive lever, and the valve disc moves together to keep the valve in the direct or branch position, and the dial feeds back the disc position; When the drive device is instructed, the drive lever and the pottery disc moves together to keep the valve in the direct or branch position, and feedback the position signal to operate the electrical switch and the feedback signal when the valve disc is in place.
