Sanitary Diaphragm Valve manufacturers introduce what fields it can be used in?
1. Places where sanitary diaphragm valves are used:
1. Corrosive
2. Medium with particles
3. Requirement of *, such as sanitary diaphragm valves used in medicine and biology
4. Requirement of strong flow capacity and small flow resistance
2. Application fields
1. Diaphragms made of soft seals such as rubber or plastic have good sealing properties. Since the diaphragm is a wearing part, it should be replaced regularly depending on the characteristics of the medium.
2. Limited by the diaphragm material, diaphragm valves are suitable for low pressure and relatively low temperature occasions.
3. Diaphragm valves can be divided into six types according to the structural form: house type, direct current type, stop type, straight-through type, gate type and right angle type; the connection form is usually flange connection; according to the drive mode, they can be divided into manual, electric and pneumatic types, among which pneumatic drive is divided into normally open, normally closed and reciprocating types.
4. It is generally not suitable for use in pipelines with temperatures above 60 degrees or for conveying organic solvents and strong oxidizing media, nor in pipelines with higher pressures.

III. Structural features

In sanitary diaphragm valves, since the working medium contacts only the diaphragm and the valve body, both of which can be made of a variety of different materials, the valve can ideally control a variety of working media, especially for media with chemical corrosion or suspended particles. The operating temperature of the diaphragm valve is usually limited by the materials used for the diaphragm and the valve body lining, and its operating temperature range is approximately -50 to 175°C. The diaphragm valve has a simple structure and consists of only three main parts: the valve body, the diaphragm and the valve head assembly. The valve is easy to disassemble and repair quickly, and the replacement of the diaphragm can be completed on site and in a short time.
The sanitary diaphragm valve has a flexible diaphragm or a combined diaphragm installed 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.
