HD743H heavy hammer hydraulic slow closing check butterfly valve

HD743H heavy hammer hydraulic slow closing check butterfly valveZhejiang Kezhong Valve Co., Ltd. is a professional manufacturer of hydraulic butterfly valves, named after the heavy hammer type closing valve, which is commonly used for the outlet of circulating water pumps and the inlet of water turbines. This product is a heavy hammer hydraulic control butterfly valve. The hydraulic control butterfly valve is opened by hydraulic drive with an oil pressure of 13-16MPa, reducing the volume of the relay. During the opening process, the heavy hammer is lifted at the same time, and the lifted heavy hammer is used to store energy and close it, eliminating the energy storage tank. After opening, it is locked and automatically put into operation, and the hydraulic system automatically maintains pressure. The heavy hammer does not fall down, and the valve disc does not shake. When turned off, there is no need for a power oil source, and the locking pin is automatically released and turned off according to the predetermined program, which is simple and reliable, greatly simplifying the hydraulic system. Adopting double eccentric/triple eccentric valve plates, the horizontally installed valve shaft is raised a certain distance on the centerline of the pipeline, so that the lower half of the valve plate has a larger water facing area than the upper half. It can use the action of dynamic hydraulic force to help the valve close and reduce the weight of the heavy hammer. The simple and compact hydraulic device, butterfly valve control cabinet, electrical automatic control box, relay, and control oil pipe are gathered together with the valve, without the need for additional configuration by the user. This valve can achieve local control, remote control, and linkage control, meeting the requirements of unmanned and few person duty, and is an ideal new type of pipeline control equipment.

HD743H heavy hammer hydraulic slow closing check butterfly valveThe heavy hammer type valve has a higher safety factor compared to other hydraulic control valves, and it has the dual functions of a gate valve and a check valve. The valve opens as the heavy hammer is lifted and maintains a fixed potential energy for a long time. When the oil pump motor unit malfunctions or loses power, the heavy hammer slowly descends with the gravity of the earth and closes the valve. Mainly installed at hydropower stations and turbine inlets, used as turbine inlet valves or installed at pump outlets of various pumping stations such as water conservancy, power, and water supply and drainage, where safety requirements are higher. There are mainly butterfly valves, transmission systems, hydraulic stations, heavy hammer energy storage mechanisms, and locking devices

HD743H heavy hammer hydraulic control slow closing check butterfly valveEquipped with gate valve cut-off function for water pump outlet and check valve check function, and integrating mechanical, electrical, and hydraulic systems, it occupies a small area. The accumulator provides the main power source for valve opening and closing, which can be operated on site or centrally controlled by a microcomputer; Mainly installed at hydropower stations and turbine inlets, used as turbine inlet valves or installed at pump outlets of various pumping stations such as water conservancy, power, and water supply and drainage. The accumulator type hydraulic controlled slow closing check butterfly valve consists of four parts: butterfly valve, transmission mechanism, hydraulic station, and electric control box

HD743H heavy hammer hydraulic control slow closing check butterfly valveIt is a device used in fluid systems to control the direction, pressure, and flow rate of fluids. A valve is a device that enables the flow or cessation of media (liquids, gases, powders) in piping and equipment, and controls their flow rate. Valves can be used to control the flow of fluids such as air, water, steam, corrosive media, mud, oil, liquid metal, and radioactive media. Valves are control components in pipeline fluid transport systems, used to change the cross-sectional area of the passage and the direction of medium flow. They have functions such as diversion, cutoff, throttling, check, diversion, or overflow pressure relief. Valves used for fluid control range from simple globe valves to valves used in complex self-control systems, with a wide variety of varieties and specifications. The nominal diameter of valves ranges from extremely small instrument valves to industrial pipeline valves with a diameter of up to 1m. Valves can be used to control the flow of fluids such as water, steam, oil, gas, mud, corrosive media, liquid metals, and radioactive fluids. The working pressure of valves can range from. 13MPa to 1MPa, and the working temperature ranges from -269 ℃ to 143 ℃. The control of valves can adopt various transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, pneumatic hydraulic, spur gear, bevel gear drive, etc; Valves can operate according to predetermined requirements under the action of pressure, temperature, or other forms of sensing signals, or simply open or close without relying on sensing signals. Valves rely on driving or automatic mechanisms to make the opening and closing parts move up, down, slide, swing or return, thereby changing the size of their flow channel area to achieve their control function.
