The invention relates to an outward protruded integrated throttle valve, which comprises a valve body and a valve core. It is characterized in that: the valve body (1), the valve core (2) and the throttle holes (3) inside the valve core are integrated molded; the ends of throttle valve molded by copper punch are valve bodies (1), while its center is a rotary table valve core (2) with throttle holes (3); the axial projection of valve core (2) is petal shape, the center projection is rotary table (4) and the edge are several petals (5), while each petal, the petal and the rotary table, and the petal and the valve body are both integrated. The invention replaces former short-pipe throttle valve or plate-hole throttle valve with integrated structure to avoid the space between valve core and valve body to improve the anti-deformation and the anti-leakage abilities of throttle valve, with stable property, reduced raw material consumption and lower cost. |
