TWD175886S - Flow control valve - Google Patents

Abstract

[Use of article]; This article is a control valve that can control the pressure, speed, flow rate, flow direction, etc. of the pressure fluid supplied to the oil and air pressure system. ;When in use, first, the control signal is input through the wire. When a control signal is input, pilot fluid is supplied from the pilot valve part to the valve body inside the main body, and the valve body is driven to switch the communication/blocking of the flow path between the ports. Thereby, the pressure, speed, flow rate, flow direction, etc. of the pressure fluid flowing through the aforementioned flow path are controlled. For example, low-speed air supply can be performed to gradually increase the initial pressure of the air pressure system, or rapid exhaust can be performed to interrupt the air supply and rapidly discharge the residual pressure of the air pressure system. ;[Design Description];The control valve system of this design includes: a main body, which has ports on the left side, right side and bottom side; and a pilot valve part, which is located on the upper part of the main body. ; The pilot valve part is equipped with wires for receiving control signals. Housed inside the main body are: a valve body (not shown), which is driven by the pilot fluid; and a needle valve (not shown), which adjusts the flow rate of the pressure fluid. The pilot valve portion is provided with a first operating member for manually operating the valve body, and the bottom surface of the main body is provided with a second operating member for manually operating the needle valve.
