Product Description

DYQ940X/F/H-10C/16C/25/40P/R/RL mounted electric eccentric hemisphere valve body center axis and hemisphere center axis form a size offset, and only on one side of the valve body with a sealing pair of valves. A valve that is opened and closed by rotating the ball around the center line of the valve body.
, the working principle of:
The ball with a circular channel is used as the opening and closing part, and the ball rotates with the valve stem to realize the opening and closing action of the valve. The opening and closing part of the ball valve is a ball with a hole, rotating around the axis perpendicular to the channel, so as to achieve the purpose of opening and closing the pipeline and equipment media.
 Eccentric half ball valve is classified according to the installation method
Installation method classification:
Valve internal parts from the upper part of the valve to install and disassemble the valve, the advantage is that maintenance, no need to remove from the pipeline, you can replace the parts in the valve.
Side-mounted eccentric half ball valve
The structure of the valve is integrated, and the internal parts are a valve that is installed and disassembled from the side.
Characteristics of,
1. Low pressure loss:
When fully opened, the water loss is zero, and the flow channel is smooth; The inner cavity is automatically cleaned, the spool rotates 90 degrees, automatically washes the inner cavity of the valve body, cleans the debris in the medium, and the medium will not be deposited in the valve cavity. The sphere is hemispherical, and the circulation has the highest CV value, which enhances the system effect of the pump and reduces the wear and corrosion to the lowest degree.
2. Resistance to particle wear:
The use of the principle of double eccentricity in the closing process, only in the last moment of the ball crown to the seat, without friction, and the sealing ring on the seat surfacing wear-resistant self-lubricating alloy, not easy to wear, not easy to wash; Knife shaped ball mouth between the ball crown and the seat has the role of cleaning and shearing, not easy to scale.
3. Automatic compensation seal reliable:
Positive pressure, the use of eccentric principle, the ball and the seat closer and tighter, so as to get a good seal; In any case, the floating valve seat under the pressure, the valve seat automatically push to the ball, the higher the pressure, the more tightly the valve seat to the ball, so as to get a good seal; Can maintain a durable tight seal, can adapt to harsh working conditions. In the long-term use, if the valve seat seal is worn or damaged, the valve seat will automatically push to the ball under the action of the spring, so as to get a good automatic compensation function.
4. Suitable for high flow rate media:
Because the ball is hidden on one side of the valve cavity, the straight flow path is formed without flow resistance, and the solid eccentric fixed crankshaft is free from vibration and noise in the medium of high flow rate.
5. Long life switch easy:
No vulnerable parts, due to the role of eccentricity, the sealing surface of the ball and the seat in the valve opening and closing process
* Off, so that the surface of the seat and the ball crown between the spherical surface without scratches to do frictionless rotation, effectively reduce the operating torque, easy to operate; The automatic compensation function of the valve greatly improves the life of the valve.
