Description

Technical Field

[0001] The invention relates to the technical field of valve diaphragm processing, in particular to a valve diaphragm production device. Background Art

[0002] The valve is a control component in the fluid delivery system, which is used to cut off, regulate, guide, prevent backflow, stabilize pressure, and divert the liquid or air flow at the two ends of the valve. There are many types of valves, among which the diaphragm valve is equipped with a flexible valve diaphragm or a combined diaphragm in the valve body and the valve cover, and its closing part is a compression device connected to the diaphragm. The valve seat can be a weir shape or a pipe wall of a straight flow channel. The advantage of the diaphragm valve is that its operating mechanism is separated from the medium passage, which not only ensures the purity of the working medium, but also prevents the possibility of the medium in the pipeline impacting the working parts of the operating mechanism.

[0003] Metal diaphragms are usually made by cold pressing with metal sheets as raw materials. Nowadays, metal diaphragms are usually produced by inserting them in single pieces. When the metal sheet is stamped, due to the strong fit between the metal sheet and the die, gas exists between the metal sheet and the die. At this time, the gas squeezed by the metal sheet will increase in pressure, thereby hindering the deformation of the metal sheet and increasing the energy consumption of the equipment. When the pressing is completed and then taken out, the metal diaphragm that fits the die has to be manually pulled out, which is very laborious. Summary of the invention
