What are the precautions when installing the filling machine valve

Since the development of filling machine equipment, it has a high degree of automation and higher filling measurement accuracy. It is suitable for non-gas 84 solution, ethanol solution reagent, reagent water and other solutions in various geometric shapes such as plastic bottles and glass bottles. Quantitative filling. In order to ensure the normal filling of liquid, the valve installation of the filling machine is the key.

Before the valve is installed, it should be installed after passing the pressure test. Carefully check whether the specifications and models of the valve are consistent with the drawings, check whether the parts of the valve are in good condition, whether the opening and closing valves can rotate flexibly, whether the sealing surface is damaged, etc. After confirming that they are correct, You are ready to install. Specifically, the following points should be done: Before the valve is installed, it is necessary to confirm that the valve meets the design requirements and relevant standards.

Before installation and adjustment, the valve body of the pre-installation restrictor valve must be completely cleaned, the maintenance kit of the restrictor valve must be replaced, the material pipe must be cleaned, and all restrictor valves must be tested for leaks.

Before installing the diaphragm, the internal limit block must be installed in place, and at the same time, pay attention to the direction of the limit block before installing the diaphragm. The diaphragm should be installed in a ventilated state with a pressure of 5.5bar. Turn the diaphragm clockwise to half a turn, and at the same time confirm the direction of the diaphragm, the internal limit block is consistent with the direction of the diaphragm, and install all the diaphragms with the above method.

When the control valve is installed on the material pipe, it must be seen that the direction of the diaphragm is consistent with the material pipe. The torque of the torque wrench must be adjusted before tightening the screws. The torque is 4.5N·M. After tightening the 4 screws diagonally, install all the restrictor valves and throttle valves on the material pipe. Make the next adjustment. Before adjusting the flow rate of the restrictor valve and the throttle valve, it is necessary to test the throttle valve and get a reasonable data.
