Abstract

The invention discloses a flow control flow. The flow control flow comprises a flow control valve casing, an upper valve clack, a lower valve clack, a first elastic part and a second elastic part; theflow control valve casing is internally provided with a pore passage; the upper valve clack comprises a downward spherical surface; the lower valve clack comprises a spherical groove matched with thespherical surface, and the spherical surface is opposite to the spherical groove; the first elastic part is connected between the upper valve clack and the pore passage in a sealed mode; the second elastic part is connected between the lower valve clack and the pore passage in a sealed mode; and an arc-shaped surface is connected to the circumferential side of a notch of the spherical groove andprotrudes upwards. The flow control valve can be controlled according to the flow rate.

Description

technical field [0001] The invention relates to the fields of building pipelines, flow control valves and the like, and in particular relates to a flow control valve. Background technique [0002] Flow control valve, its basic structure is composed of valve disc, valve disc, valve cover and handle, etc. The valve disc is installed in the cavity of the valve disc, and after installing the packing, the valve cover and the inner cavity of the valve disc form a complete cavity. , and then install the handle on one end of the disc, and use the rotation angle of the control handle to move in the range of 0 to 90 degrees to realize the opening and closing of the flow control valve. This structure in the existing technology usually realizes the opening and closing of the valve clack manually, and the valve clack cannot be opened or closed according to actual needs, and the flow rate of the fluid flowing through the flow control valve cannot be controlled. The valve is controlled. ...
