Manual diaphragm valve is a manually operated diaphragm valve. It is a new type of diaphragm valve with disinfection and sterilization function. It is also a product with a tail valve. There are many kinds of materials, such as stainless steel valve body is one of them, the characteristics of this valve is that it has a certain resistance to acid and alkali substances, and its maintenance is also relatively convenient, we don’t have to worry about leakage and growth of bacteria. Today is mainly to introduce the working principle of manual diaphragm valve.

In fact, the working principle of the manual diaphragm valve is similar to that of the pinch valve. We will pass the flowing material in a straight line. The effect of this is that it will generate a relatively small pressure, which can avoid turbulent flow, so that it is more convenient for us to switch on and off. At the same time, another advantage of this manual diaphragm valve is that it can perform throttling operation. We will install a throttling setting near the bottom of the valve body, and its throttling setting is very popular. The last thing to say is that this kind of diaphragm valve can prevent the harm caused by valve failure. Once the diaphragm fails, this kind of valve body can accommodate shallow flow, and then it will be simpler for us to tighten the valve shell.

Common manual diaphragm valves in life can be divided into straight-through structure and weir-type structure. Except for the difference in the valve body and diaphragm, the other structures of these two kinds of valves are almost similar. However, the two structures also have their own characteristics. For example, the diaphragm valve of the weir structure is very suitable for use under high pressure working conditions. Straight through the diaphragm valve, the bottom wall of its valve body can be parallel to the flow, so that the flow will pass through the valve unimpeded. Another thing to talk about is the function of the diaphragm. Why do we install the diaphragm, because by installing the diaphragm at the bottom of the compressor, we can ensure that when the diaphragm is fully opened, the diaphragm can be quickly lifted to allow the flow to flow smoothly. The above All content is an introduction to the working principle of manual diaphragm valves.
