Cold Air Suction Valve
Introduction:
With electric and manual two functions;
Special suction valve with the help of negative pressure self-priming nipple embedded seal door open and closed valve body (valve plate) structure, working Angle of 0° ~ 90°, 0° closed, 90° fully open.
The embedded sealing ring is made of high polymer silicone material. Air leakage rate ≤0.1% after suction valve is closed. Q235B, δ=12mm; The output shaft is made of 40Cr alloy.
The opening requirement of the electric actuator is 0 ~ 90° Angle stroke, the operation mode is switch quantity adjustment (fully open and fully closed), and has 4-20mA output signal;
The output torque of the electric actuator is increased by one stage on the basis of calculation, which is not less than 8kN·m. Worm gear worm gear mechanism requires the use of nodular cast iron worm gear and alloy steel worm material.
Muffler block type muffler structure, muffler muffler volume ≥30dB(A), pressure loss ≤500Pa; The shell is made of Q235B, δ=6mm, and the hole plate of the silencing element is made of high quality cold rolled galvanized sheet, δ=1.5mm.
