The invention provides a diaphragm valve. The diaphragm valve comprises a valve body, a valve cover, a valve base, a valve core mechanism and a diaphragm, wherein the wall of the valve body is provided with a material inlet, and the bottom of the valve body is provided with a first open end; the wall of the valve cover is provided with an air supply interface, the top of the valve cover is provided with a second open end, a valve cap is spirally connected with the second open end, the valve cover covers the valve body, and a cavity is formed between the valve cover and the valve body; the valve base is arranged on the first open end of the valve body; one end of the valve core mechanism stretches out of the second open end of the valve cover, and the other end of the valve core mechanism is slidably arranged on the valve base; and the diaphragm is arranged in the cavity, is connected with the valve core mechanism in a driving manner, and is used for dividing the cavity into an upper air supply chamber and a lower material chamber, the air supply chamber is communicated with the air supply interface, and the material chamber is communicated with the material inlet. The diaphragm valve provided by the invention has the advantages that the valve core mechanism is located reliably, the normal working of the diaphragm valve is guaranteed, thereby being beneficial to smooth discharge after the material enters the diaphragm valve; and the volume of the diaphragm valve is decreased, and the structure is more compact.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a diaphragm valve. Background technique [0002] There is a diaphragm in the diaphragm valve, which separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover and divides it into two chambers, so that the parts such as valve sleeves and seals above the diaphragm are not in contact with the medium, and the corrosion of the components by the medium is avoided. There will be no medium leakage, and it is often used to transport toxic and harmful medium valves. However, due to the limitation of diaphragm materials, diaphragm valves are suitable for occasions where the temperature is relatively low and the solid content in the medium is low. [0003] The invention patent application with the application number 91107124.5 discloses a manual diaphragm valve. The diaphragm valve disclosed in the invention patent application has many parts and a large ...
