Will the internal structure of the terminal block of the electric water seal butterfly valve automatically close when the power is cut off? Pneumatic ball valve connection code: 1 indicates internal thread, 4 indicates flange type, 6 indicates welding, 7 indicates wafer type; Structural code of pneumatic ball valve: floating type: 1 means through flow, 2 means Y-shaped tee, 4 means L-shaped tee, 5 means T-shaped tee; Fixed type: 0 means hemispherical straight through, 6 means four-way flow channel, 7 means straight through flow to, 8 means L-shaped tee, 9 means Y-shaped tee;
、 Solution 3: We usually use the lens sealing method to solve the problem. The sealing of the upper cover and lower cover of the electric butterfly valve and the sealing between the valve seats can be effectively solved by using the lens gasket sealing method. If we use a flat seal, the seal may be much worse at high temperature, which may cause leakage. However, the use of lens pads can help us achieve satisfactory results.
