Bevel valve structure

Bevel valve  located in the export of high pressure drain pipe, valve with cylindrical fixed shell, with 4 ~ 6 parallel in the direction of flow of the rib conical head into 90 ° of the cone fixed on the valve shell, with one activity steel valve set set (or inside), on the outside of the cone valve cover with the annular space between the cone is used to discharge. The flow can be adjusted by using screw drive to move the valve sleeve back and forth along the flow direction. The flow coefficient reached above 0.85 when all opened.  Bevel valve  structure is simple and easy to operate. Because the weight of the whole valve is borne by the anchor bolt at the root and the valve shell is cantilever protruding, the structural stress condition is unfavorable. ​

Timer drain valves

Timer drain valves  opening and closing speed, blowdown effect is good, use tap water pressure source, hydraulic valve opening and closing, less investment, lower equipment investment cost, which can realize remote control, automatic control, centralized control management, reduce labor intensity, no noise, the valve is simple.
