Abstract
The utility model discloses a low-noise ball valve. The ball valve comprises a valve body (6), a valve seat (2), a pressure-reducing and noise-reducing ball body (4), a valve rod (5), a valve cover (1) and a sealing ring (3), wherein the valve cover (1) is installed on the valve body (6) via the sealing ring (3), the pressure-reducing and noise-reducing ball body (4) is installed in the valve seat (2), and the pressure-reducing and noise-reducing ball body (4) is connected with the valve rod (5). The ball valve is characterized in that a plurality of labyrinth-type pores (7) are arranged on one sidewall of the pressure-reducing and noise-reducing ball body (4), enough grooves (8) are formed at the other side of the pressure-reducing and noise-reducing ball body (4), and the labyrinth-type pores (7) are connected with the grooves (8). The ball valve can avoid phenomena of high pressure difference, high noise, high flow speed and cavitation, and is suitable for being used in a high-pressure-difference pipeline for reducing a pressure, decreasing and controlling a flow speed, reducing noise and reducing vibration.
Description
Technical field
The utility model relates to universal machine valve manufacturing technology, is specifically related to a kind of low noise ball valve.
Background technique
Existing ball valve mainly contains compositions such as valve body, valve seat, spheroid, valve rod, valve gap.The O shape mouth structure that its sphere structure is commonly as shown in Figure 1, the shortcoming of this structure be can not reduce pressure, reduce flow velocity, controlling noise, adjusting function is poor.
Summary of the invention
The purpose of the utility model is: a kind of low noise ball valve is provided, and this ball valve can be avoided High Pressure Difference, noise is big, flow velocity is high and cavitation phenomenon, and it is applicable to that the High Pressure Difference pipeline reduces pressure, minimizing and control flow velocity, reduces noise and reduces vibration.
The technical solution of the utility model is: it comprises valve body, valve seat, step-down noise reduction spheroid, valve rod and valve gap, and valve gap is installed on the valve body, and step-down noise reduction spheroid is installed in the valve seat, connects valve rod on the step-down noise reduction spheroid; It is characterized in that: several mazy type apertures are arranged on the sidewall of step-down noise reduction spheroid, and the opposite side of step-down noise reduction spheroid is opened enough grooves, and the mazy type aperture communicates with groove.
The beneficial effect of the utility model is: 1, step-down noise reduction spheroid reduces pressure through the control media flow velocity, effectively eliminates cavitation erosion, reduces the harm that noise and vibration bring; 2, step-down noise reduction spheroid progressively step-down slow down, reduced destruction to valve inside, restriction upstream device flow velocity has improved product working life, reduces noise protection environment; 3, have interchangeability with conventional ball, can dismantle easily or safeguard.
