Abstract
The utility model relates to a Y-shaped valve, in particular to a Y-shaped slurry valve with a curve concave surface valve clack, which comprises a valve body, wherein a valve seat is arranged in the valve body, a valve clack is arranged in a valve cavity in the valve body and is connected with a valve rod, the valve rod extends out of the valve body, the valve clack and the valve seat form a sealing pair, the valve clack comprises a valve clack body and a connecting sleeve, and an annular groove is arranged on the valve clack body, so when media flow through the valve from a position under the valve clack, and the media are dispersed after entering the groove of the valve clack and rotate, so the flow speed of the media is decelerated, the impact force of the media is obviously reduced, the brushing degree of the media on the valve clack body is reduced, the stress unbalance of the valve clack body is also reduced, the vibration force is reduced, and the noise is reduced. Simultaneously, the weight of the curve concave surface valve clack is light, and the starting and closing torque is greatly reduced.
Description
Technical field
The utility model relates to a kind of Y valve door, relates in particular to a kind of curve concave surface flap Y type slurry valve.
Background technique
Mostly the flap of widely used in the market Y type slurry valve as depicted in figs. 1 and 2 is unitary solid, the flap of cylinder conical surface seal.Adopt the valve of this flap structure in practical application, to have many shortcomings: 1, behind the valve opening, under the impact of medium, be prone to produce unbalanced force, make that valve vibration is relatively more serious, noise is big at the flap place; 2, when the valve vibration amplitude was big, flap very easily came off, when serious even valve rod is fractureed; 3, flap adopts solid construction, wastes rapidoprint, has increased the manufacture cost of valve; 4, flap weight is bigger, and valve opening and closing moment is big, causes the energy waste of valve actuator.
The model utility content
The purpose of the utility model provides a kind of curve concave surface flap Y type slurry valve, and vibrations are low during its overcurrent, noise is little.
For solving the problems of the technologies described above, the utility model comprises: valve body is provided with valve seat in the valve body; Establish flap in the valve pocket in the valve body, flap connects valve rod, and valve rod stretches out outside the valve body; Flap and valve seat form sealing pair; Flap comprises: valve petal body and connecting sleeve, said valve petal body is provided with annular recess, is respectively equipped with sealing surface on valve seat and the valve petal body.
Said groove is a U-shaped.
Radially be provided with stiffening rib along valve petal body in the said groove.
Valve body comprises: left valve barrel and right valve barrel, left valve barrel and right valve barrel link together, and are provided with valve seat between left valve barrel and right valve barrel.
Described flap and valve rod all are positioned at right valve barrel, and valve rod stretches out outside the right valve barrel.
Described stiffening rib is 2 roads or more than 2 roads.
The utility model adopts the flap that is provided with annular recess; Make medium when flap bottom flows through valve, thereby medium get into and disperse behind the groove of flap and rotation has reduced the flow velocity of medium, and the medium impact force is obviously reduced; Alleviated the degradation degree of medium to valve petal body; Flap is also reduced by force unbalance thereupon, and vibration force reduces, and noise reduces.Flap is in light weight simultaneously, opens and closes moment and reduces greatly.
