Problems solved by technology
Manual pressure adjustment is suitable for low-pressure homogenizers with medium and small flow rates. Large-flow and high-pressure homogenizers cannot be adjusted manually; the hydraulic control pressure adjustment system has high manufacturing costs and complex structures. Oil leakage in the hydraulic system will cause homogeneous material pollution. Problem (this is crucial to the food industry); Pneumatic pressure regulation requires that the user must have an air source and an air handling device, and the pneumatic pressure regulation method is greatly affected by the load

Embodiment Construction
[0011] Such as figure 1 As shown, the motor 8 drives the pinion 6 to rotate through the reducer 7, the pinion 6 meshes with the bull gear 5, and the bull gear 5 can move axially relative to the pinion 6 to a certain extent. The large gear 5 is fixedly connected with a hollow screw 4, so when the large gear 5 drives the hollow screw 4 to rotate, the hollow screw 4 will produce an axial displacement, and the end of the hollow screw 4 is connected to the spring seat 3 through a bearing , so that the translation of the spring seat 3 occurs. The translation of the spring seat 3 will cause the change of the compression degree of the compression spring 2, thereby changing the elastic force of the compression spring 2, so the hollow screw 4 constitutes a translation mechanism for squeezing the compression spring 2.
[0012] The elastic force of the compression spring 2 acts on the valve core 9 through the ejector rod 1, and the other end of the valve core 9 also bears the pressure of...

The invention discloses a method for controlling the homogenization pressure of a homogenizer. A compression spring is arranged, the elastic force of which acts on the valve core of the homogenization valve through a push rod, and the elastic force of the compression spring can be adjusted. The valve opening of the homogenizing valve controls the homogenizing pressure, and the motor drives a translation mechanism to squeeze the compression spring to adjust its elastic force. The present invention drives a translation mechanism by a motor to achieve different degrees of compression of the compression spring, thereby adjusting the elastic force of the compression spring, and finally realizing the control of the homogeneous pressure. This control method reduces manual operations, and is easy to realize automatic control. Make pressure control more precise and efficient. It avoids the risk of contamination of materials in the hydraulic pressure regulating system, and also avoids the problem that the pneumatic pressure regulating method is greatly affected by the load. Compared with the existing hydraulic pressure regulating and pneumatic pressure regulating methods, it is not only safer and more reliable, but also the pressure regulating mechanism Costs can also be reduced.
Description
technical field [0001] The invention relates to a pressure control method, in particular to a method for automatically controlling the homogenization pressure in a homogenizer. Background technique [0002] The existing homogenization pressure control methods of the homogenizer include manual pressure regulation, hydraulic control pressure regulation and pneumatic pressure regulation. Manual pressure adjustment is suitable for low-pressure homogenizers with medium and small flow rates. Large-flow and high-pressure homogenizers cannot be adjusted manually; the hydraulic control pressure adjustment system has high manufacturing costs and complex structures. Oil leakage in the hydraulic system will cause homogeneous material pollution. Problem (this is crucial to the food industry); Pneumatic pressure regulation requires that the user unit must have an air source and an air handling device, and the pneumatic pressure regulation method is greatly affected by the load.
