Embodiment Construction

[0008] The present invention will be further described below with reference to the accompanying drawings.

[0009] The present invention is a fully automatic gas-liquid flow control valve, as shown in the figure, it mainly includes a valve body, which is different from the prior art in that: the valve body is composed of an upper valve body 2 and a lower valve body 1, the upper The gas-liquid channel 8 of the valve body 2 and the lower valve body 1 communicates with each other. A valve core 3 is arranged in the valve body. The B end 10 of the core 3 is located in the gas-liquid channel 8 , the valve body is provided with a position sensor 6 matched with the positioning block 5 , and the A end of the valve core 3 is connected with the drive motor 7 .

[0010] In specific implementation, the drive motor receives different instructions from the CPU to open the flow rate of the valve to control the flow rate of gas and liquid. The positioning block is installed on the valve core,...

Abstract

The invention discloses a fully-automatic gas and liquid flow control valve which is characterized in that a valve body consists of an upper valve body and a lower valve body, the upper valve body is mutually communicated with a gas-liquid channel of the lower valve body, a valve core is arranged in the valve body and is matched with the gas-liquid channel, a positioning block is arranged at the A end of the valve core, the B end of the valve core is positioned in the gas-liquid channel, a position sensor matched with the positioning block is arranged at the valve body, and the A end of the valve core is connected with a drive motor. The fully-automatic gas and liquid flow control valve can be in joint control with a touch screen, a PLC (Programmable Logic Controller) and a gas (liquid) mass flow meter to realize automatic high-precision gas and liquid flow control; the valve core can be directly connected with the drive motor, and a transmission part has a simple structure. Compared with the prior art, the fully-automatic gas and liquid flow control valve has prominent substantive features and significant progress.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a full-automatic gas-liquid flow control valve, and in particular to its mechanical connection structure. Background technique [0002] Comparative document, application number: ZL200620092947.0, applicant: Ma Xinbo, application date: 2006.08.22, this case discloses an "automatic valve adjustment device". The screw of the valve passes through the gearbox. It is characterized in that the turbine pair is formed by the turbine and the worm in the gearbox. The inner circle of the turbine is closely matched with the circumference of the screw, and the two ends of the worm pass through the casing of the gearbox horizontally. , A hand wheel is installed at one end of the worm rod, and a motor is installed at the other end. [0003] The current similar products have no fine flow control, long valve response time, low flow control precision, complex structure of transmission parts, etc. ...
