Abstract
A kind of grid formula ball valve, comprises valve body and valve ball, and valve body includes medium gateway, is provided with valve seat in valve body, and valve ball is arranged in described valve seat, is provided with a screen in valve seat, and screen, between valve ball and medium gateway, is provided with noise abatement hole on screen.On screen, be provided with regulator plate, described regulator plate and screen are rotatably connected by bearing pin, and the area of overlap in regulator plate and noise abatement hole is 0%～100% of noise abatement hole area.The utility model arranges screen in ball valve, is provided with noise abatement hole on screen, the speed while flowing through valve for reducing high-velocity fluid, thus reduce noise; Meanwhile, the area in the noise abatement hole of screen can regulate, and avoids the obstruction of medium.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to the valve for fluid control, particularly a kind of grid formula ball valve.
Background technique:
Ball valve is widely used in fluid control.In prior art, in the time that the flowing velocity of controlled fluid is higher, because the area of passage of valve place fluid changes, now often produce larger noise, be unfavorable for the improvement of working environment and affect working life of valve; In the situation that medium contains impurity particle, noise is more serious, but also has the possibility of filter medium clogging.
Summary of the invention:
The purpose of this utility model is to provide a kind of grid formula ball valve, and described this grid formula ball valve will solve in prior art the technical problem that produces larger noise when liquid speed is higher at valve place.
This grid formula ball valve of the present utility model, comprise valve body and valve ball, described valve body includes medium gateway, in valve body, be provided with valve seat, described valve ball is arranged in described valve seat, it is characterized in that: in described valve seat, be provided with a screen, described screen, between described valve ball and medium gateway, is provided with noise abatement hole on screen.
Further, on described screen, be provided with regulator plate, described regulator plate and screen are rotatably connected by bearing pin, and the area of overlap in regulator plate and noise abatement hole is 0%～100% of noise abatement hole area.
Concrete, in valve seat, being provided with the screen described in two, two screens are between the upper and lower every setting.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model arranges screen in ball valve, is provided with noise abatement hole on screen, the speed while flowing through valve for reducing high-velocity fluid, thus reduce noise; Meanwhile, the area in the noise abatement hole of screen can regulate, and avoids the obstruction of medium.
Brief description of the drawings:
Fig. 1 is the structural representation of grid formula ball valve of the present utility model.
Embodiment:
Embodiment 1:
As shown in Figure 1, grid formula ball valve of the present utility model, comprise valve body 1 and valve ball (not shown), described valve body 1 includes medium gateway, in valve body 1, is provided with valve seat, and described valve ball is arranged in described valve seat, wherein, in described valve seat, be provided with a screen 2, described screen 2, between described valve ball and medium gateway, is provided with noise abatement hole on screen 2.
Further, on described screen 2, be provided with regulator plate (not shown), described regulator plate and screen 2 are rotatably connected by bearing pin (not shown), and the area of overlap in regulator plate and noise abatement hole is 0%～100% of noise abatement hole area.
Concrete, in valve seat, be provided with 2, two screens 2 of screen described in two between the upper and lower every setting.
The working principle of the present embodiment is: screen 2 is set in ball valve, on screen 2, is provided with noise abatement hole, and the speed while flowing through valve for reducing high-velocity fluid, thus reduce noise; Meanwhile, the area in the noise abatement hole of screen 2 can regulate, and avoids the obstruction of medium.
