Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The directional terms mentioned in the present invention, such as: up, down, left, right, inside, outside and other directional terms, are only for reference figure 1 direction. Accordingly, the directional terms used are for illustration only and not for limitation of the present invention.

[0038] Such as Figure 1-5 As shown, the present invention discloses an industrial ball valve, which includes a valve body, a ball 2 and a valve stem 6; The valve body includes a first valve body 1 and a second valve body 22 , and a valve seat 3 is provided between the first valve body 1 , the second valve body 22 and the ball 2 . The upper part of the second valve body 22 close to the side of the first valve body 1 is provided with a valve stem opening matching with the valve stem 6 , and the lower end of the valve stem 6 is connected to the ball 2 thro...

Abstract

The invention relates to the technical field of ball valves, in particular to an industrial ball valve comprising a valve body, a ball and a valve stem; the ball is installed in the valve body, and a valve seat is arranged between the valve body and the ball; one end of the valve stem Pass through the valve body and connect with the sphere; the other end of the valve stem is set with a manual adjustment mechanism; the middle part of the valve stem is equipped with a cylinder driving mechanism; both the manual adjustment mechanism and the cylinder driving mechanism are used to drive Control the rotation of the valve stem; there is a switching mechanism between the manual adjustment mechanism and the cylinder drive mechanism. This application combines the cylinder driving mechanism with the manual adjustment mechanism, so that the ball valve can be controlled by the cylinder driving mechanism or the manual adjustment mechanism to adjust the opening or closing of the control valve through the switching mechanism, which can effectively reduce the possible problems caused by the single control mode. A malfunction that renders the valve unusable occurs.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to an industrial ball valve. Background technique [0002] Ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries. A valve that rotates around the axis of the ball valve can be used for the regulation and control of fluids (fluid media such as gases, liquids, and tiny particles). In the field of industrial applications, when the ball valve is installed in the pipeline, it can flexibly control the confluence, diversion and switching of the flow direction of the medium. [0003] Traditional ball valves are classified according to the driving method: pneumatic ball valve, electric ball valve, manual ball valve, and generally there is only one driving method. [0004] When a ball valve with a single drive mode is in use, if the drive device...
