Floating type pneumatic valve pneumatic valve _ _ soft seal pneumatic components factory valve industry

Pneumatic pneumatic valve floating pneumatic valve overview: floating pneumatic valve has a full size and reducing two kinds of structure. Used for conveying viscous, easy and slagging medium pneumatic valve should be used on the pipeline of full size, convenience of paraffin purging through on a regular basis. Used for conveying gases or physical properties similar to water medium should be used on the pipeline of reducing pneumatic valve, because of its weight is about 30% lighter than the full size of the pneumatic valve, is conducive to reducing load pipeline, reduce the cost. Floating type pneumatic valve drive mode for manual, worm gear, pneumatic, electric or hydraulic. Floating type pneumatic valve working principle: floating pneumatic valve seat choose ptfe, registration more polystyrene polymer materials, such as good sealing performance, single material is relatively soft. Because the material is soft, but also to achieve certain sealing pressure, is bound to increase the open-close torque, as far as possible in order to improve the situation, the pneumatic components factory valve industry with double inclined plane elastic sealing ring or v-shaped groove elastic sealing ring structure design, use of the pipe pressure promote aerodynamic body, help seal. When the medium pressure is small, sealing ring and the aerodynamic body contact area is small, so it has large sealing pressure, ensure reliable sealing. Medium pressure, sealing ring and the aerodynamic body contact area increased. So the seal ring can bear larger medium thrust without damage. For low working pressure of the pneumatic valve, considering the medium pressure does not ensure reliable seating, but after long-term use of prestressing force and damping, reason for low pressure, low pressure or vacuum conditions with pneumatic valve, spring loaded valve seat sealing structure, pneumatic valve to ensure long-term reliable seal. Soft seal pneumatic valve features: 1, the fluid resistance small, soft seal pneumatic valve is all valve class * a small fluid resistance, even reducing pneumatic valve, the fluid resistance is small. 2, switch is quick, convenient, as long as the valve rod rotation 90 °, to complete the pneumatic valve fully open or close the action, it is easy to realize rapid opening and closing. 3, seat sealing performance is good. Most of the pneumatic valve's sealing ring use the elastic material, such as ptfe soft sealing structure is easy to guarantee the opening and closing, and pneumatic valve sealing force with medium pressure increases with the increase in. 4, the valve stem seal and reliable. Soft seal pneumatic valve opening and closing valve stem rotation movement and not only for lifting movement, the valve stem packing seal is not easy to damage, and pour sealing stem sealing force with medium pressure increases with the increase in. 5, such as ptfe material has good self-lubrication, and pneumatic friction loss is small, so the long service life of pneumatic valve. 6, configurable pneumatic, electric, hydraulic and so on many kinds of driving mechanism, realize the remote control and automation. 7, body channel level off is smooth, can transport viscous fluid, slurry and solid particles. 8, easy to install, can be installed on any position of the pipeline in any direction. Pneumatic components factory is specializing in the production of pneumatic valve, valve industry customers can choose according to the use of temperature and pressure sealing pneumatic valve, pneumatic valve or hard seal customers also need to know about floating working principle of pneumatic valve and valve body material, the use of pressure, temperature and other related technical parameters, so that our sales staff for selection and quotation. : O cut the working principle of the pneumatic valve type O pneumatic valve internal structure fixed pneumatic valve working principle and structure of the function and working principle of pneumatic valve ( Figure)
