Eccentric Hemisphere Valve EQ940 Electric
The eccentric hemispherical valve EQ940 electric motor produced by Dazhong Valve Group adopts the principle of eccentric tightness to achieve the purpose of locking, adjusting and closing through the transmission mechanism. The sealing pair is a metal surface ring with a hard surface contact seal. The hemisphere of the valve is made of bimetal, the base metal is surfacing with different alloys, and the valve seat is also surfacing with special treatment, which can deliver zero leakage of harmful gas. This product is especially suitable for iron and steel industry, aluminum industry, fiber, tiny solid Particles, pulp, coal ash, petroleum gas and other media.
The structure adopts the principle of eccentric tightening to achieve the purpose of locking, adjusting and closing through the transmission mechanism. The sealing pair is a metal surface ring with a hard surface contact seal. When the double eccentric structure is opened, the valve core is located in the ball chamber. The flow cross-section is large, and the valve is not flushed, the valve core is not flushed when it is closed, and the spherical surface of the valve core is progressive along the valve seat when it is opened, effectively removing the fouling obstacles and achieving reliable sealing.
It is particularly effective for the mixed flow conveying of two-phase mixed flow, which is easy to scale and solid precipitation. The hemisphere of the valve is made of bimetal, and the base metal is surfacing with different alloys. The valve seat is also surfacing and is specially treated to seal The surface is combined into various types such as anti-corrosion, wear-resistant, high-strength, etc. to meet the needs of different occasions. The sealing is tight, and the transportation of harmful gases can achieve zero leakage.
The valve core of the sealing pair has a compensation amount. When the valve is worn, turn it a little more when it is closed, so that it can seal reliably and prolong the service life. In addition, the user will screw off the compression nut, adjust or replace it. The rear valve seat is still available, which avoids the disadvantages of the whole machine being scrapped after the valve seal fails.
The electric eccentric hemisphere valve can be used for wear-resistant, corrosion-resistant, high-temperature-resistant and strict sealing conditions due to the selection of bimetallic sealing pairs of different alloys (or combined balls) by surfacing.
