ManualIts advantages are as follows: 1、After the sealing surface is opened, the valve core is transferred to the ball chamber, and the sealing surface is less worn; 2、Manual eccentric hemisphere valveEasy to operate, quick to open and close, suitable for long-distance pipeline transportation, easy to deal with emergencies; 3、When opening, the spherical surface is separated from the seal seat without any contact, so the switch is light and the opening and closing torque is higher than that of the ball valveAnd other valves are much smaller; 4、When closing, the movement of the spherical surface and the valve seat at the moment of closing has a shearing effect, which can remove the adhesive scaling on the sealing surface, and the sealing is tight and reliable; 5、Manual eccentric hemisphereIt is suitable for media containing impurities, crystallization precipitation or precipitation, with very good sealing performance; 6、Manual eccentric hemisphere valveThe full diameter is straight through type. The valve body channel is connected with the pipeline connected by the pipeline as a straight pipe, with equal sectional area and negligible flow resistance; 7. The sealing locking mechanism is eccentric clamping of the fixed shaft, which can be compulsorily compensated and automatically locked, soManual eccentric hemisphere valve hasIt is characterized by strong pressure resistance, high pressure resistance, good sealing performance, etc.
