Two-way pressure spherical rotation and the characteristic of pneumatic valve products

the bidirectional pneumatic valve pressure spherical rotation characteristics
product structure, the adaptive function, based on the entropy increase principle, under the action of gravity or other force, fitness ball from any direction within the cone surface and conical surface automatically to align the center and overlap, namely under the effect of medium, the pneumatic valve core and pneumatic seat center under the condition of different heart can automatically to align the center and automatic reclosing seal.
, no friction, opening and closing, on the basis of the principle of eccentric sphere rotation moment of ball on opening left pneumatic valve seat, closing moment of ball coincide with the pneumatic valve seat, so no friction when opening and closing.
, automatic bridge wear, in the sphere or pneumatic seat isometric extension ring wear, also, on the basis of the principle of eccentric rotating spheres close ball movement to the overlap position, and under the effect of entropy increase principle automatically adjust attitude and close more and more tightly.
, based on the same principle, on the seal line plane, sphere when its closed area of swelling, opens its shrinking. , amplify the sealing pressure, line contact seal can obtain great seal pressure, make it possible to head seal for zero leakage. Embedded in its very shallow, and the characteristics of the spherical as long as the seal material choose a suitable hardness collocation and pneumatic seat of mark elimination, erosion wear resistance, good performance, in the case of zero leakage to ensure long service life.
, long service life, pneumatic valve core sealing surface with pneumatic valve seat sealing surface are all metal entities, can according to need to use gas or vacuum welding, plasma spraying, splash, etheric laser atomic infiltration method on the substrate to form homogeneous or gradient of high alloy steel, wear resistant stainless steel, hard alloy, super hard, cubic boron nitride, ceramic alloy material such as synthetic diamond layer, to adapt to a variety of different conditions, to obtain high service life.
and work under extreme temperature, this product has no rubber, plastic, such as working temperature restricted parts, pneumatic valve body material can be in below and choose the appropriate - below zero ℃ or above is ℃ above under the conditions of use, and also can be used in all kinds of corrosive medium, got greatly expand the application range.
, can be in solid liquid two phase or solid liquid gas three phase exists in the medium of use at the same time, also can be in the solid state flow medium, such as amorphous powder, solid particles, slag, tailings, thick pulp, slurry, pulp, pulp, mud concrete under the condition of use.
, fluid pressure, differential pressure, flow, temperature, the regulation of this product as part of a sphere and the pneumatic valve core is less than half of a sphere, pneumatic valve seat for the conical surface, and thus can be used for the adjustment of the fluid pressure, differential pressure, flow rate, fluid pressure, differential pressure, flow rate and temperature as the opening of the pneumatic valve core is basically a percentage of the relationship. Small open degree of advantage is particularly evident when, because of its positive small open degree, fluid relative path point to center of the pneumatic valve cavity, spurting fluid in the center of the pneumatic valve cavity mutual collision, effectively eliminate the impact of the fluid potential energy, reduce noise and vibration. Streamlined pneumatic valve core to reduce or even eliminate vortex area on the back of the negative pressure pneumatic valve core, eliminate cavitation cavitation erosion of the harm of pneumatic valve core. In large areas of the medium within the scope of opening, fluid flow, pressure, differential pressure and the relationship between the opening of the approximate percentage, the adjustable area for the opening of the ~ %, adjustable size, proportion.
