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...
