Description of the structural characteristics of the medicinal sanitary grade diaphragm valve

The medicinal hygienic diaphragm valve is remotely controlled by the drive or manually operated by the handle.
There are three basic units: the normally closed form and the switch type flue gas. The utility model has the advantages of simple structure, beautiful appearance, quick disassembly and assembly, flexibility and small fluid resistance, so it is safe and reliable.
Suitable for chemical, petroleum, metallurgical, hot water, food, pharmaceutical and other industries, water, gas, oil and corrosive environment control. The remote or manual control unit can be done using a crank.
The structural design of the diaphragm itself is net moderate or severely contaminated, very solid liquid, gas, corrosive or trimmed. A diaphragm valve in a control unit is combined to replace the more traditional control system, especially in the middle of an inert solid, easily contaminated. Diaphragm valve, a special form of shut-off valve that opens and closes a diaphragm made of a soft material that separates the body cavity from the bonnet. These diaphragm valves actually tighten the valve to distract the elastic membrane. Lu Zhenxiong's compressed compression piece is attached to the operating rod to move. When the compression member rises, it holds a high diaphragm, causing the road, the position of the falling ball, and the diaphragm pump body. Pressure, in the village (key 堰) or pressed in the lower part of the recommendation (direct type), the diaphragm valve is suitable for the use of switches and throttles.
Diaphragm valves are equipped with a flexible membrane, or attached to the compression device in the body and cover group together with a nearby membrane. The seat can be formed into a raft that may be directly flowing into the Great Wall. The advantage of the diaphragm is that the mechanism and the way it is handled, the resources are separated, not only to ensure the purity of the work, but also the influence of the organ, only the media in dealing with the possibility of working parts. In addition, the department does not require a separate tribal secret letter in any form, except for media that control the use of security devices. These diaphragm valves, as media, can only be used in many different materials when in contact with a membrane, so the key is to ideally control the operation of various equipment, especially for entering the media with corrosion or chemical particles. The diaphragm valve is a simple operation for the body membrane and lining material. The operating temperature is reduced from -50 to 175 °C. The diaphragm valve and valve body group represent the three main parts. The key to success is that it is easy to repair, and easy removal and replacement of the film can be done in the field for a short time.
The valve membrane is not only separate for the management and communication channels of the food and healthcare industry management agencies, but also for some traffic that is heavy and dangerous. Most people use synthetic rubber and plastics in engineering applications, as well as a more open body choice to face the wide range of materials used in various fields of diaphragm valves in modern industry. Health Benefits of the Membrane Membrane The diaphragm valve is designed for heavy environmental pollution and clean liquids, very rigid, natural gas, corruption-specific construction reasons or inert environments. In combination with computer control, diaphragm valves replace the more traditional control systems, especially those related to solids and simple inert environments.
These products are mainly used in the food industry, biopharmaceuticals, and electro-chemical industries, electroplating industries, such as industrial wastewater treatment, and also in semiconductor wafer fabrication. Valve membranes are particularly suitable for the delivery of liquids, viscous, corrosive, such as mud, Food, medicine, fiber adhesive solutions, pipes, because the operating valve membrane body does not touch the liquid, it is pollution-free, no need to fill the department pole seal supply can not be empty. On the seat used, this is the pressure point used to cut or connect the rubber diaphragm of the vacuum system. For loose flange connection, fast flange, welded connection. Connection point welding joint [My welding ends] Sewing connection type II [ie welding ends, the other end is inserted]. The key average working gas, air and non-corrosive. Three-way rubber membranes are used to control media, corrosive or corrosive, surface-cavity, uncoated or covered on a choice of applications to choose a different type of rubber for different operating temperatures and liquid piping.
It is used for a variety of surface materials and it has good corrosion resistance. The center of the valve and diaphragm, which causes the diaphragm to separate the lid, and the erosion of the diaphragm on the lid instead of a suitcase is a special way to reduce the key.
