Fluid is stopped, to reduce the flow velocity of fluid, so as to reduce barometric gradient, alleviates negative pressure problem, reaches reduction throttling noise
Purpose.It should be noted that the effect of flow apron 4 is the fluid for the valve port for hindering outflow valve body 3, and therefore, flow apron 4
It is the outside of the valve body 3 positioned at flow-limiting valve, and in order to realize the effect of flow-limiting valve itself, the length of the flow apron 4 of setting
Degree needs the diameter with the pipeline of installation to be defined, and prevents 4 blocking pipeline of flow apron.In addition, flow apron 4 and valve body 3
The distance between outlet need to be adjusted according to the size of flow.
The preferably circulation with the fluid of the outlet of outflow valve body 3 of the setting direction of flow apron 4 disclosed herein
Direction is vertical.Above-mentioned set-up mode can reduce the flow velocity of fluid as far as possible, to achieve the purpose that noise reduction.It can also incite somebody to action in practice
Flow apron 4 is arranged to have certain angle with the flow direction of fluid, further in order to alleviate fluid reflux the problem of, can will
Flow apron 4 is arranged to the arrangement for obtuse angle with the flow direction of fluid.
In specific embodiment, the outlet of valve body 3 will be stretched in outside the first end of spool 1, and by flow apron 4 and spool 1
First end connection.Specifically, the first end of the spool 1 stretches out the outlet of valve body 3 and installs flow apron 4 to realize to water conservancy diversion
The fixed installation of baffle 4, can be connected for flow apron 4 with the connection mode of spool 1 using screw, also can be by flow apron 4
Set and be an integral structure with spool 1, to facilitate processing, and can ensure the intensity requirement of flow apron 4.
In addition, also flow apron 4 can be installed on valve body 3, the core of the application is the outlet to flowing out valve body 3
Fluid is stopped, alleviates the problem of negative pressure produces, and then the purpose of noise reduction to reduce the flow velocity of fluid.To sum up, exist
