What are the export packaging requirements for rolling diaphragms? Diaphragm pump is a special form of shut-off valve that appeared in the 1920s. Its opening and closing parts are a diaphragm made of soft material, which separates the valve body cavity from the valve cover cavity and driving components, hence it is called a diaphragm valve. This product adopts a special process to wrap polytetrafluoroethylene on the valve body, and the diaphragm parts are lined with PTFE diaphragm and nitrile rubber gasket, ensuring that all components in the valve chamber have the same corrosion resistance. This product has good throttling characteristics, corrosion resistance, and particle resistance, and reliable sealing performance. It can be widely used in various corrosive fluids and fibrous and powdered media.
Diaphragm valves use corrosion-resistant lined valve bodies and corrosion-resistant diaphragms instead of valve core components, utilizing the movement of the diaphragms for adjustment. The valve body material of the diaphragm valve is made of cast iron, cast steel, stainless steel, cast iron, and engineering plastic. The diaphragm valve is suitable for various corrosive media, diaphragm discs, diaphragm valves, valve seats, workpieces, and other industries.
The diaphragm valve has a simple structure, low fluid resistance, and larger flow capacity compared to other types of valves of the same specification; No leakage, can be used for regulating high viscosity and suspended particle media. The diaphragm connects the medium to the upper chamber of the valve stem and the diaphragm, so that the medium will not leak out.
The flow characteristic of the diaphragm valve is close to the fast opening characteristic, which is approximately linear before 60% of the stroke, and the flow rate changes little after 60%. Pneumatic quick opening is widely used in industries such as gas, liquefied gas, asphalt, food, pharmaceuticals, carbon, crude oil, gas, etc.
The correct way to use a diaphragm valve: 1. Open the gas pressure in the rear chamber of the pneumatic valve (to cause rapid expansion of pulsating gas), and the gas flow is amplified by an electric motor induced by a nozzle. (Pressure adjustment range) Combine the upper chamber of the valve with the diaphragm, so that it is located low on the compressed air.
The leakage of diaphragm valves is mainly used for air pressure, usually 60 ° C (it can only be used) 0-100 ° C (it can only be used for air pressure) 2.
The interior of the diaphragm valve body is made of rubber, plastic, or plastic materials. When the handle, cone, or power is applied, it is sealed outdoors. After atomization testing and natural cooling, it is tilted or perpendicular to the horizontal height according to on-site needs to adjust the indicator.
Low energy consumption through the above: 1. Switch the switch to a position that can be used for water pressure. 2. Open and close or adjust to the energized position through the railing. 3. Adjust the flow rate, pressure, and start-up pressure fluctuations of the valve body based on the pressure of the medium. 4. This series of products can convert power into dynamic and control. The shaft adopts the same installation size. Once a current break or vibration is found, adjust the position correctly. Replace the piston and valve body.
Before installation, it is necessary to ventilate and clean the debris inside the gas supply pipeline. Pay attention to the correct direction of gas flow and connecting pipes during installation.
The room temperature and high temperature temperature of the differential pressure single machine should comply with the specified temperature of the pulse valve and the outdoor temperature.
