Embodiment Construction

[0026] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0027] The invention provides a pressure-variable fluid volume control device based on local constant pressure, which specifically includes a pressure-stabilizing tank, a multi-way tank, a master control valve, a Unicom valve, a small valve, a large number of valves, an emptying valve, a purge valve, a cleaning Valves, level detection devices and tank holders.

[0028] The surge tank is in the shape of a cylinder, sealed at both ends, with a pressure resistance of 0.6 MPa, and a large flange is designed on the top to facilitate maintenance and repair. A liquid level detection device and an emptying valve are installed on the large flange cover. The liquid level detection device is used to control the liquid level of the material, and the emptying valve is used to release the pressure inside the surge tank. The emptying valve i...

Abstract

The variable pressure fluid volume control device based on local constant pressure and the precise volume control method technology provided by the present invention, the volume control device includes a surge tank, a multi-way tank, a master control valve, a Unicom valve, a small valve, a large number of valves, and a liquid level detection device; a large flange is designed on the top of the surge tank, and a liquid level detection device and an emptying valve are installed on the large flange cover, and the emptying valve is connected to the exhaust pipeline; The pressure tank and the material outlet are connected; the master control valve, the Unicom valve, the small valve, the large valve, the emptying valve, the purge valve, and the cleaning valve are controlled by the control system; the Unicom valve controls whether the material enters the stable Pressurized tank; a small amount of valve controls the flow of material from the surge tank to the material outlet; a large number of valves controls the flow of material through the multi-way tank to the material outlet. The simultaneous improvement of the filling accuracy and filling speed of the liquid product filling machine is realized.

Description

technical field [0001] The invention is suitable for a precise volume control system of a liquid product filling machine, and in particular relates to a variable pressure fluid volume control device and a precise volume control method based on local constant pressure. Background technique [0002] With the development of the chemical industry, there is an urgent need to increase the filling speed of chemical materials to improve the production efficiency of the chemical industry. And due to the characteristics of the chemical industry, it is necessary to increase the filling speed while ensuring the filling accuracy. [0003] At present, the volume control method commonly used in the market controls the filling accuracy through the opening of the valve, which can achieve the filling of liquid products with high precision and low speed or low precision and high speed. However, this control method cannot change the material pressure, and cannot realize the filling of high-pre...
