The valve body comprises a valve, a butterfly plate and a valve rod, the butterfly plate and the valve rod are arranged on the valve, the transmission mechanism comprises a counter weight and a lever, an oil inlet pipe is arranged on one side of the transmission mechanism, the lever is connected with the valve rod, the hydraulic station comprises a motor, an energy accumulator, an oil pump, a coupler, an oil tank and an oil pipe joint, the motor is connected with the oil pump through the coupler, and the oil pump is connected with the oil inlet pipe on the transmission mechanism through the oil pipe joint. The weighted hydraulic control butterfly valve is mounted at a water inlet of a water turbine volute and provides a reliable and safe working condition for a unit in stop maintenance, water leakage of the unit is decreased when the unit is stopped for a long time, water is rapidly filled when the unit is started so that the unit rapidly enters a working state, and runaway of the unit can be prevented.

Description

The heavy hammer type hydraulic butterfly valve
Technical field
The present invention relates to hydraulic butterfly valve, specifically a kind of heavy hammer type hydraulic butterfly valve.
Background technique
Hydraulic butterfly valve is at present domestic and international more advanced pipeline control apparatus, mainly is installed on water power plant water turbine import, as the water turbine inlet valve; Or be installed on the exit of pump of all kinds of pumping plants such as water conservancy, electric power, plumbing, substitute the function of safety check and gate valve.During work, valve coordinates with the pipeline main frame, according to the Calculations of Hydraulic Transient principle, by default keying program, effectively eliminates the pipeline water hammer, realizes the reliable cut-off of pipeline, plays the effect of protection pipeline security of system.Yet existing hydraulic butterfly valve flow resistance coefficient is large, automaticity is not high, function is simple, stable performance is poor.
Summary of the invention
In order to solve the above-mentioned technical problem existed in prior art, the invention provides a kind of heavy hammer type hydraulic butterfly valve, by valve body, driving mechanism, hydraulic station, intelligent electric-controlled case forms, described valve body comprises valve body, be arranged on butterfly plate and valve rod on valve body, described driving mechanism) comprise weight and lever, one side of driving mechanism is provided with oil inlet pipe, described lever is connected with valve rod, described hydraulic station comprises motor, accumulator, oil pump, coupling, fuel tank and oil connection, described motor is connected by coupling with oil pump, described oil pump is connected with the oil inlet pipe on driving mechanism by oil connection.
Further, described intelligent electric-controlled case is arranged on hydraulic station.
Further, between described butterfly plate and valve body be three eccentric metal sealing or two eccentricity rubber seal structure.
Further, also be provided with hand pump on described hydraulic station, for the valve opening and closing under system debug and special operation condition.
Further, described valve body is connected with intake pipe, and the diameter of intake pipe is 1000-2000mm.
Heavy hammer type hydraulic butterfly valve of the present invention is arranged on the water inlet of spiral case, and reliable safe operating conditions is provided while overhauling for compressor emergency shutdown; Reduce the unit water leakage when unit is shut down for a long time, rapid water filling during start, make unit enter fast working state; Can also prevent that unit from flying the anecdote part.
The accompanying drawing explanation

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Figure 1-4, heavy hammer type hydraulic butterfly valve of the present invention is by valve body 1, driving mechanism 2, hydraulic station 3, intelligent electric-controlled case 4 forms, wherein valve body 1 comprises valve body, be arranged on butterfly plate 5 and valve rod 6 on valve body, driving mechanism 2 comprises weight 7 and lever 8, one side of driving mechanism 2 is provided with oil inlet pipe 9, lever 8 is connected with valve rod 6, hydraulic station 3 comprises motor 10, accumulator 11, oil pump 12, coupling 13, fuel tank 14 and oil connection 15, motor 10 is connected by coupling 11 with oil pump 12, oil pump 12 is connected with the oil inlet pipe 9 on driving mechanism 2 by oil connection 15.Intelligent electric-controlled case 4 is arranged on hydraulic station 3.
Be three eccentric metal sealing or two eccentricity rubber seal structure between butterfly plate 5 and valve body, guarantee sealability, avoid leaking.
Also be provided with hand pump 16 on hydraulic station 3, for the valve opening and closing under system debug and special operation condition.
Manually drive valve: shake hand pump 16, pressure oil enters oil cylinder through high-pressure rubber pipe, promotes piston and drives valve.
Manually close valve: oil cylinder internal pressure oil is through closing soon, slowly throttle valve, high-pressure rubber pipe, normally closed manually operated valve oil sump tank 14, and under the effect of weight potential energy and moving Hydraulic Moment, valve rod 6 and butterfly plate 5 rotations realize closing valve.
Valve body 1 is connected with intake pipe, and the diameter of intake pipe is 1000-2000mm.
Shown in the above and figure is only the preferred embodiment of the present invention.It should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
