Description
Technical field
The utility model belongs to valve technology field, and in particular to one kind is capable of the three-eccentric-butterfly-valve of noise reduction.
Background technique
Three-eccentric-butterfly-valve is due to being to develop in recent ten years most with good flow regulating function and closing sealing characteristics
One of fast valve kind.The use scope of butterfly valve is very extensive.Its kind used and quantity still are continuing to expand, and to height
Temperature, high pressure, heavy caliber, high leakproofness, long-life, excellent control characteristic and the multi-functional development of a valve.Its reliability and its
He reaches higher level at performance indicator.Existing three-eccentric-butterfly-valve is severe in High Pressure Difference, high flow rate etc. generally all without noise reduction measure
It carves and is used under operating condition, when design, then must be taken into consideration noise reduction problem, and excessive valve noise can generate vibration, and then influence valve
Service life, uncontrolled noise also results in adjacent channel equipment damage, serious to result even in safety accident.
Summary of the invention
The utility model is intended to provide a kind of three-eccentric-butterfly-valve for capableing of noise reduction, can be effectively reduced flow velocity, the pressure of medium
Power, noise, noise reduction reduce valve vibration, valve service life are able to extend, to reduce the whole use cost of valve.
According to the technical solution of the utility model, the three-eccentric-butterfly-valve for capableing of noise reduction, including valve body, valve plate, valve rod
And bottom cover, the upper and lower ends of the valve body axis hole are equipped with bearing, valve rod is mounted in the axis hole of valve body using bearing, valve rod
Lower end is encapsulated by being fixed on the bottom cover of body base, and the valve plate is arranged in the channel of valve body, and valve rod passes through valve plate and leads to
Pin or key transmission connection are crossed, the water outlet of the valve body is connected with noise reducing plate by short joint flange.
Further, the first spirotallic gasket is equipped between the short joint flange and valve body, between short joint flange and noise reducing plate
Equipped with the second spirotallic gasket.
Further, the part that the noise reducing plate corresponds to valve channel is densely covered with hole, and the pore size in hole is identical.
The utility model has the beneficial effects that: reducing flow velocity, pressure, the noise of medium by increasing noise reducing plate, subtract
The vibration that minor valve generates, it is ensured that the service performance of valve and service life；The small sircle hole energy of uniform dense distribution on noise reducing plate
Enough dirty media effectively blocked in pipeline prevent pipeline to do stifled；Noise reducing plate structure is simple, easy to process, and production cost is low, peace
Fill convenient disassembly；Short joint flange, which avoids, encounters noise reducing plate damage sealing element when valve plate fully opens.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model noise reducing plate.
Description of symbols: 1- valve body, 2- valve plate, 3- valve rod, 4- bearing, 5- bottom cover, the first spirotallic gasket of 6-, 7- noise reduction
Plate, the second spirotallic gasket of 8-, 9- short joint flange.
Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below.
It is as shown in the figure: to be capable of the three-eccentric-butterfly-valve of noise reduction, including valve body 1, valve plate 2, valve rod 3 and bottom cover 5, in 1 axis of valve body
The upper and lower ends in hole are equipped with bearing 4, and the bottom of valve body 1 has been bolted bottom cover 5, and valve rod 3 is mounted on valve using bearing 4
In the axis hole of body 1, the lower end of valve rod 3 is encapsulated by bottom cover 5.Valve plate 2 is arranged in the channel of valve body 1, and valve rod 3 passes through valve plate 2
And it is sequentially connected by pin or key.The water outlet of valve body 1 is connected with noise reducing plate 7 by short joint flange 9.
Specifically, being equipped with the first spirotallic gasket 6 between short joint flange 9 and valve body 1, set between short joint flange 9 and noise reducing plate 7
There is the second spirotallic gasket 8, is fixed by bolt and nut, sealing effect is good.It gathers the part in corresponding 1 channel of valve body of noise reducing plate 7
There are out multiple small sircle holes, hole is uniformly distributed, and pore size is identical.
Working principle: by increasing by one section of short joint flange 9 after valve body 1 and installing noise reducing plate 7 additional, short joint flange 9 is avoided
Valve plate 2 encounters noise reducing plate 7 and damages sealing element when fully opening, noise reducing plate 7 is made of to open multiple small sircle holes, noise reduction on one block of plate
Hole is uniformly distributed, and pore size is identical, replaces a big spout using multiple apertures, to reach the flow velocity for reducing medium, pressure
Power, the purpose of noise, reduce valve vibration, extend valve service life, reduce the whole use cost of valve, while energy
Enough dirty media effectively blocked in pipeline prevent pipeline to do stifled.
