Description

TECHNICAL FIELD

[0001] The utility model relates to valve technical field, concretely relates to an eccentric hemisphere valve convenient to remove. BACKGROUND

[0002] The eccentric hemisphere valve is a relatively new type of ball valve, which has some advantages due to its structure, such as no friction in opening and closing, no wear in sealing, and small torque in opening and closing. This can reduce the size of the actuator. With a multi-rotation electric actuator, the valve can be used for regulating and tightly cutting off the medium, and is widely used in petroleum, chemical industry, urban water supply and drainage, and other strict cutting conditions.

[0003] The existing eccentric hemisphere valve is integrally arranged with the base during installation, so that it cannot be removed from the base for maintenance and replacement after a long period of operation.

By cooperating the installation block, the installation groove, and the round block, the eccentric hemisphere valve can be conveniently removed from the base after installation, which facilitates subsequent replacement and maintenance. By cooperating the pulley, the brake pad, and the wear-resistant pad, the eccentric hemisphere valve body can be conveniently moved, and the whole body can be positioned after moving, which ensures stable operation.

[0005] Although the above-mentioned patent can drive the insertion rod to disengage from the insertion groove by the thread cooperation between the round block and the round groove, so as to take out the eccentric hemisphere valve body from the base, but when it is necessary to control the cooperation or disengagement between the insertion rod and the insertion groove, the round block needs to be continuously rotated in the round groove to drive the insertion rod to move left and right in the horizontal groove, which is a relatively complex operation process, thereby it is difficult to improve the control speed of the insertion rod in the horizontal groove.
