How to judge the switch when the pneumatic dust removal butterfly valve actuator is opened? Characteristics/pneumatic butterfly valve
(1) The double axial force structure is selected, which has the sealing function of tightening as the closer it is, and the sealing performance is reliable.
(2) The raw materials of the sealing pair are stainless steel plate and nitrile acid and alkali resistant vulcanized rubber, which have a long service life.
(3) The rubber seal ring can be located on either the valve body or the butterfly plate. The media with different characteristics can be selected by customers.
(4) The butterfly plate adopts bent structure, with high compressive strength, large total overcurrent area and low fluid density.
(5) The overall painting can reasonably avoid rusting, and if the rubber seals of high-pressure gate valves are more sealed, they can be applied to different media.
(6) This valve has a double sealing function, so it will not be controlled by the inflow of media during installation, nor will it be endangered by the indoor space. It can be installed in all directions.
(7) It is light in weight, light in weight, reliable in performance, simple in supporting facilities, and capable of commodity circulation. It is very suitable for clean liquid and steam.
、 Triple eccentric butterfly valve: it must be resistant to high temperature and must be hard sealed, but the leakage is large; To achieve zero leakage, soft sealing must be used, but it is not resistant to high temperature. In order to overcome the contradiction of double eccentric butterfly valve, the butterfly valve was eccentric for the third time. The so-called third eccentricity is that the shape of the sealing pair is not a regular cone, but a slanted cone.
