V pneumatic regulating valve ( The wafer) The structure principle of _ pneumatic components factory valve industry

Pneumatic valve pneumatic V type pneumatic regulating pneumatic valve ( The wafer) Overview: the wafer pneumatic regulating pneumatic valve is a kind of right back to the transformation of the high precision control valve, its novel structure, excellent workmanship, sealing, used to adjust the medium inside the pipeline pressure and flow rate. Choose different material, can be respectively suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, and other media. V pneumatic regulating valve ( The wafer) Structural principles: (1) the body USES the direct integration design, the valve with actuator can be connected directly, to avoid the disadvantages of bracket connection and ordinary pneumatic valve because of the middle flange connection, which may cause leakage. (2) V pneumatic regulating valve ( The wafer) When closing the nominal pressure stress, three pneumatic core orientation offset is not greater than zero. 1 mm, greatly improving the control valve leakage standard, under the condition of high temperature, pneumatic valve closed force, achieve the aerodynamic body deformation, than ordinary V pneumatic valve to extend the service life of more than 1 times. (3) pneumatic control pneumatic valve can improve the valve body, valve core, the valve stem, seat the whole concentricity, reduced the mechanical friction, inherit the pipeline pressure difference, from the original 25 kg increased 40 kg. (4) sex hard seal structure, the valve seat sealing ring with a spring, elastic clingy pneumatic sealing type below, to seal and pneumatic friction compensation function. (5) the valve core is the 90 ° V type gap design, flow characteristic is approximate equal percentage, adjust the control performance of precision. 6 small flow resistance, flow capacity is 2 ~ 3 times of ordinary single-seat regulating valve, make the V pneumatic valve has higher cost performance. All landowners at three design to do the corner type single cylinder actuators with positioning structure, making linear motion actuator piston rod, eccentric shaft rotates 90 Angle, the Angle of movement, with the valve connection, is open to the closed state, eliminate the valve in the opening position, radial swing the role of stress caused by the piston rod bushing friction losses and shaft sealing channeling phenomenon. End of pneumatic actuator adopts imported meters type cylinder, cylinder piston adopts wear-resisting four fluorine with positioning, piston ring USES steam rose type two-way non-return Y type piston rings, thrust, wear-resisting, chromium plating on the surface of the piston rod is made of high quality steel processing, zui large extent reduce the coefficient of friction, the piston rod in the movement, will remain sealed zero leakage. Pet-name ruby pneumatic actuator piston rod positioning bearing used in powder metallurgy self-lubricating bearing and shaft seal steam rose type, pneumatic actuators using AP67 level protection design, dustproof and waterproof. Attending pneumatic actuator and positioner bracket integrally cast stainless steel pieces, feedback shaft adopts universal joint, automatic adjustable core type connection. V pneumatic regulating valve ( The wafer) Selection methods: customers when choosing pneumatic valve pneumatic control, need to confirm the good (1) product model (2) nominal size (3) nominal pressure (4) body material (5) those use the trim material temperature 7) medium pipeline valve connection pet-name ruby actuators role requirements whether attending actuators with attachments ⑪ special requirements need to elaborate. We according to the selection of technical parameters above quotation. : flange pneumatic regulating pneumatic valve characteristics characteristics of pneumatic hard seal pneumatic valve characteristics of high vacuum pneumatic valve
