First, the introduction of side-mounted eccentric hemisphere valve


是指阀体中心轴线与半球中心轴线形成尺寸偏置,且仅在阀体一侧设置密封副的阀门。 Side-mounted eccentric hemisphere valve refers to a valve in which the central axis of the valve body is offset from the central axis of the hemisphere, and a sealing pair is provided only on one side of the valve body. A valve that rotates a sphere around the centerline of the valve body to achieve opening and closing. The internal parts are an eccentric hemisphere valve installed and disassembled from the side.

Working principle of side-mounted eccentric hemisphere valve

The side-mounted eccentric hemisphere valve is a valve that uses a ball with a circular channel as the opening and closing member, and the ball rotates with the valve stem to realize the opening and closing action. The opening and closing part of the ball valve is a ball with a hole, which rotates about the axis perpendicular to the channel, so as to achieve the purpose of opening and closing the pipeline and the equipment medium.

Classification of side-mounted eccentric hemisphere valve installation methods

Top-loading Eccentric Hemisphere Valve
The internal parts of the valve are installed and disassembled from the upper part of the valve. The advantage is that during maintenance, the parts in the valve can be replaced without removing them from the pipeline.
Side mounted eccentric hemisphere valve
气动阀门 The structure of the valve is one-piece, and the internal parts are a pneumatic valve installed and disassembled from the side .

Fourth, the characteristics of side-mounted eccentric hemisphere valve

Low pressure loss
When fully opened, the water loss is zero, and the flow channel is completely unblocked; the inner cavity is automatically cleaned, the valve core is rotated by 90 degrees, and the inner cavity of the valve is automatically flushed to clean the debris in the medium, and the medium will not be deposited in the valve cavity. The sphere is hemispherical, with the highest CV value in circulation, which enhances the system effect of the pump and minimizes wear and corrosion.
Resistant to particle wear
Using the principle of double eccentricity, during the closing process, the ball crown leans against the valve seat only at the last moment without friction, and the sealing ring on the valve seat is welded with a wear-resistant self-lubricating alloy, which is not easy to wear and repair. The spherical crown and the valve seat have the function of cleaning and shearing, and are not easy to scale.
Automatic compensation and reliable seal
At positive pressure, using the principle of eccentricity, the ball and valve seat are closed closer and tighter to obtain a good seal; when the floating valve seat is under pressure, the valve seat is automatically pressed against the ball. The higher the pressure, the valve The more the ball is seated toward the ball, the tighter it gets, so as to get a good seal; it can maintain a long-lasting tight seal and can adapt to harsh working conditions. Under long-term use, if the valve seat seal is worn or damaged, the valve seat is automatically tightened against the ball under the action of the spring, thereby obtaining a good automatic compensation function.
Suitable for high flow media
Because the sphere is hidden on one side of the valve cavity, a straight flow channel is formed without flow resistance, and the solid eccentric fixed crankshaft has no vibration and noise in a high-flow medium.
Long life with easy switching
No wearing parts, due to the eccentric effect, the sealing surface of the ball and the seat during the valve opening and closing process
Completely detached, so that there is no friction between the seat surface and the spherical surface of the ball crown for frictionless rotation, effectively reducing the operating torque and light operation; the automatic compensation function of the valve greatly improves the life of the valve.

Five, side-mounted eccentric hemisphere valve maintenance

电动球阀 带来很大的方便。 This valve has a top-loading design, and the ball crown and the supporting ball are loaded from the upper part of the valve; during maintenance, you only need to open the bonnet and hang out the crown and the supporting ball to perform maintenance and seal rings and other accessories. Down, this brings great convenience to underground pipelines, especially for atomic power engineers, to use electric ball valves .
Colleagues of this valve during the maintenance operation can keep the medium in the pipeline without wasting energy, which eliminates many previous auxiliary work by the user and makes maintenance easier.
In some specific occasions, the valve can not affect the normal operation of the pipeline system during the emergency repair. As long as the upper assembly is quickly closed after removing the ball assembly, the pressure operation of the pipeline can be resumed immediately, which reduces the loss of benefits caused by the emergency repair valve. To a minimum.
