  • Waterproof hammer high-speed intake and exhaust valve

    Waterproof hammer high-speed intake and exhaust valve

    Waterproof hammer high-speed intake and exhaust valve is a kind of equipment used to prevent water hammer phenomenon, especially suitable for the pipeline system which is prone to sudden pressure change and impact in the water transmission pipeline. Its main functions include preventing a large amount of water from splashing, reducing the impact on the inside of the exhaust valve, extending the service life of the exhaust valve, and limitin

  • C2F double flanged force transmission joint

    The double flange force transmission joint has short structure, reasonable design, reliable sealing, convenient loading and unloading, can compensate the axial displacement of the pipeline within a certain range, transmit the axial push and pull force, and has the functions of adjusting the maximum expansion amount and preventing the nozzle from loosening. It can be used instead of U-tube, bellows and other expansion joints, and is an ideal solution to the problems of pipeline installation and expansion.

  • CF single flange force transmission joint

    The CF type single flange loose sleeve force transmission joint is an important connector used in the pipeline system, mainly used for the loose sleeve connection of pumps, valves and pipelines and other equipment. It consists of a loose sleeve expansion joint, a short pipe flange and a force transmission screw. It adopts a trapezoidal rubber sealing ring, is fastened by gland bolts, and uses rubber compression elastic deformation to achieve static sealing, effectively preventing medium leakage

  • ZF Cone Valve (Energy-dissipation Valve)

    Cone valve is a suitable for high head, large flow conditions, no vibration, no cavitation operation, continuous discharge flow control of new valve products. Due to the use of inverted cone plunger spool named, referred to as the cone valve. Because of its excellent energy dissipation effect, it is also called energy dissipation valve.

    Cone valve is a suitable for high head, large flow conditions, no vibration, no cavitation operation, continuous discharge flow control of new valve products. Due to the use of inverted cone plunger spool named, referred to as the cone valve. Because of its excellent energy dissipation effect, it is also called energy dissipation valve. Cone valve in addition to the end of the channel is provided with a conical valve core, all the moving parts are set in the valve flow channel outside, so that the valve body internal flow is usually smooth, large flow and pressure drop loss is small, the entire working range will not produce cavitation and vibration, and in the small flow still has good flow control effect. The conical valve developed by our company has a fixed inverted conical structure. It is supported by hydraulic design and four guide wing blades used to reduce vibration. The flow rate is controlled by the front and back movement of the external movable casing. The valve body is respectively provided with metal-to-metal valve seats and supplementary soft sealing valve seats, which constitute a composite valve seat to ensure sealing performance. When discharged into the atmosphere, the water flow spreads at a wide cone angle and breaks down into a thin spray pattern, expending energy in the air. Usually according to the actual needs, can be required to control the water flow area, then install a different form of deflector at the outlet, which can not only mix the air with sufficient water, but also concentrate the flow. The results of the cone valve test showed no significant vibration, and the discharge coefficient was around 0.9 with or without the shroud when the fixed cone was fully open. ZF cone valve is mainly used in hydropower stations, reservoirs and urban water supply and drainage areas.
