Magnetic flap side mounted level gauge interface to install pneumatic valve type selection

side magnetic flap level gauge when installation need to connect to form within the measured container, two connecting pipe generally adopt the DN flange connection, in order to facilitate future maintenance convenience, generally need to interface with pneumatic valves, if in the production of liquid level meter parts failure or need for routine maintenance, we may through close the pneumatic valve, emptying of the medium inside the liquid level meter, very easy to repair. Pneumatic valve type is more than one, how the joint to choose the appropriate type, need to users according to the working conditions of the specific analysis and selection. Below we for pneumatic valves for a general introduction, the kinds of convenient choice targeting everyone in the choice of pneumatic valve.
the first: pneumatic ball valve
open-close part ( A sphere) Driven by pneumatic valve stem, and around the pneumatic ball valve axis rotation movement of the pneumatic valve. Can also be used on regulation and control of fluid, including hard seal v pneumatic valve the v-shaped ball core of carbide surfacing with strong shear force between metal pneumatic valve seat, especially suitable for fiber, tiny solid material, such as medium. And more general pneumatic ball valve on the pipe not only can the confluence of flexible control medium, shunt, and the flow switch, at the same time also can close any channel and make the other two. This kind of pneumatic valves shall generally be installed in the pipeline. Classification of pneumatic ball valve: pneumatic ball valves, electric pneumatic valve, pneumatic valve manual ball. General magnetic flap and lateral loading level gauge flange interface docking with manual pneumatic ball valve is enough. He has wear-resisting, sealed performance is good, switch light, long service life. Flange connection of the pneumatic ball valve is compared commonly.

the second, by the pneumatic valve by pneumatic valve, pneumatic valve is also called door belongs to compulsory sealed pneumatic valve, in pneumatic valve is closed, so must to pressure pneumatic disc, to force a sealing surface does not leak. When medium by pneumatic disc below into the pneumatic valve, operating force required to overcome resistance, pneumatic stem and packing of the friction force is produced by medium pressure and thrust, close the pneumatic valve force than the pneumatic valves open force is big, so the larger the diameter of the pneumatic valve stem, or pneumatic stem top bending failure happens. According to the connection mode is divided into three types: flange connection, threaded connection, welding connection. When high pressure side magnetic level gauge turning ontology own sewage pneumatic valve will be replaced for the threaded connection of the high pressure pneumatic valve that dock with the tank flange joints is flange connection by the pneumatic valve. By the pneumatic than brake solenoid valve structure simple, manufacturing and maintenance are convenient, fluid resistance is big, needed for opening and closing force is bigger, that this is a less pneumatic ball valve.

the third, brake pneumatic valve advantages: the opening and closing more effort. Is compared with the pneumatic valve, because whether on or off, ram direction are vertical to the phase with medium flow.
disadvantages: easy cause erosion and abrasion, surface maintenance more difficult. Dimension is bigger, open needs certain space, open and close time is long. The structure is complex.
the advantages and disadvantages of the above analysis is not complete, and the Angle of analysis is the lateral loading magnetic level gauge with turning tank flange joint pneumatic valve installation options, if you need to understand the advantages and disadvantages of three kinds of pneumatic valve in detail, you can go to baidu encyclopedia search. Under normal circumstances, the magnetic level gauge with turning tank flange joint of pneumatic valve installation option is pneumatic ball valve or by the pneumatic valve, and according to the above analysis point of view, in order to ensure to close quickly and closed tight, the problems of general choice can quickly close and rigor good pneumatic valve, ball is more most choose pneumatic ball valve. But this choice has more experience in general site users choose accuracy, the user generally can choose according to actual needs and working condition of pneumatic valve.
