Description
Technical field
This utility model belongs to valve technology field, and in particular to a kind of noise reduction subtracts the gate valve of sound.
Background technology
Valve is in fluid system, for controlling the device of the direction of fluid, pressure, flow.Valve is can to make to match somebody with somebody
Medium in pipe and equipment（Liquid, gas, powder）Flowing stops and can control the device of its flow.Valve is pipeline fluid
Control unit in induction system, it are for changing path section and media flow direction, with water conservancy diversion, cut-off, throttling, only
Return, shunting or the function such as overflow pressure relief.
The gate valve of prior art, due to cavitation erosion, causes very big noise, so as to cause the pollution of sound.
Therefore, the gate valve that a kind of noise reduction of invention subtracts sound seems very necessary.
Utility model content
The purpose of this utility model is to provide the gate valve that a kind of noise reduction subtracts sound, to solve proposition in above-mentioned background technology
The big problem of noise.
For achieving the above object, this utility model provides following technical scheme：A kind of noise reduction subtracts the gate valve of sound, including valve
Bar, handwheel, valve stem nut, gland, filler, valve gap, valve body, valve seals, silencing block and adpting flange, the valve rod
It is flexibly connected with handwheel by shaft coupling；The valve rod is arranged below valve stem nut；The valve stem nut is fixedly connected with filler；
Described filler is provided with gland；Described filler is arranged below valve body；The valve body is provided with valve gap；The valve body has
Adpting flange；The valve body is provided with valve seals with the junction of adpting flange；The valve seals both sides are provided with noise reduction
Block.
Further, described filler gland is fixedly connected with filler by fixing bolt.
Further, the silencing block is symmetric with regard to valve seals with silencing block.
Further, the valve gap includes bonnet, and bottom flange, and bonnet, is fixedly connected by nut with bottom flange.
Technique effect of the present utility model and advantage：The noise reduction subtracts the gate valve of sound, can cause valve by arranging silencing block
The lower noise of door, prevents the sound caused due to cavitating than larger, can prevent liquid from flowing out by arranging valve seals,
Corrosion pipeline, the utility model, simple structure, the effect that noise reduction subtracts sound are good, with preferable use value and practical value.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- valve rods；2- handwheels；3- valve stem nuts；4- glands；5- fillers；6- valve gaps；7- valve bodies；8- valve bodies

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.Embodiment in based on this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
This utility model provides the gate valve that a kind of noise reduction as shown in Fig. 1 subtracts sound, including valve rod 1, handwheel 2, valve rod spiral shell
Female 3, gland 4, filler 5, valve gap 6, valve body 7, valve seals 8, silencing block 9 and adpting flange 10, the valve rod 1 pass through
Shaft coupling is flexibly connected with handwheel 2；The valve rod 1 is arranged below valve stem nut 3；The valve stem nut 3 is fixed with filler 5 and is connected
Connect；Described filler 5 is provided with gland 4；Described filler 5 is arranged below valve body 7；The valve body 7 is provided with valve gap 6；Described
Valve body 7 has adpting flange 10；The valve body 7 is provided with valve seals 8 with the junction of adpting flange 10；The valve body is close
8 both sides of seal are provided with silencing block 9.
Further, described filler gland 4 is fixedly connected with filler 5 by fixing bolt.
Further, the silencing block 9 is symmetric with regard to valve seals 8 with silencing block 9.
Further, the valve gap 6 includes bonnet, and bottom flange, and bonnet, is fixedly connected by nut with bottom flange.
Operation principle：The noise reduction subtracts the gate valve of sound, can cause the lower noise of valve by arranging silencing block 9, prevent
The sound caused due to cavitating can prevent liquid from flowing out than larger by arranging valve seals 8, corrosion pipeline, the practicality
New, simple structure, the effect that noise reduction subtracts sound are good, with preferable use value and practical value.
Using technical scheme described in the utility model, or those skilled in the art's opening in technical solutions of the utility model
Give, design similar technical scheme, and reach above-mentioned technique effect, fall into protection domain of the present utility model.
