Diaphragm valve body type selection diaphragm valve of choice is the pump selection is the most important part. Diaphragm valve body types, commonly used through a single seat, through two-seater, angular, diaphragm, small flow, tee, eccentric rotation, butterfly, sleeve, spherical and other 10 species. Before choosing a valve , carefully analyze the medium, process conditions, and parameters of the control process, gather enough data to understand the system requirements for the diaphragm pump, and determine the type of valve to be used based on the data collected. In the specific choice, from the following aspects:
(1) The shape of the spool is mainly based on the selected flow characteristics and unbalanced forces and other factors to consider.
(2) Wear resistance When the fluid medium is a suspension containing high concentration of abrasive particles, the valve core, the valve seat joint surface will be severely rubbed each time it is closed. Therefore, the flow of the valve should be smooth, the valve's internal material to be hard.
(3) Corrosion resistance Due to the corrosive medium, try to choose a simple structure of the valve in the case of regulatory function.
(4) Medium temperature, pressure When the medium temperature, high pressure and changes, should use the valve core and valve seat material by temperature, pressure changes in small valves.
(5) to prevent flash and cavitation flash and cavitation only produce liquid medium. In the actual production process, flash and cavitation not only affect the calculation of flow coefficient, but also the formation of vibration and noise, so that the valve life is shorter, so the valve should be selected to prevent flash and cavitation.
A bending product is a type of product that is created by bending or shaping a material into a specific shape or form. This process is often used in manufacturing to create products such as metal pipes, tubing, and sheet metal components.
Bending Products can be made from a variety of materials, including metals such as steel, aluminum, and copper, as well as plastics and other materials. The bending process can be done using a variety of techniques, including press bending, roll bending, and rotary draw bending.
Some common examples of bending products include:
- Metal pipes and tubing for plumbing, HVAC systems, and industrial applications
- Sheet metal components for machinery and equipment
- Bent wire products such as coat hangers and wire baskets
- Bent plastic components for consumer products and automotive applications
Bending products are often used in applications where strength, durability, and precision are important. The bending process allows manufacturers to create products that are custom-designed to meet specific requirements, and can be used in a wide range of industries and applications.
