Embodiment 1
[0032] like figure 1 As shown, this embodiment provides a flow-controllable double-sphere special ball valve group 100 for powder and slag, which mainly includes a valve body 1 , a valve group switch ball 3 and a flow control ball 5 . Wherein, the valve group switch sphere 3 is arranged inside the valve body 1, and is positioned at one end of the valve body 1; the top of the valve group switch sphere 3 is connected with the first transmission shaft 4, and the first transmission shaft 4 is connected with the first actuator (in the figure Not shown), the valve group switch ball 3 can rotate under the drive of the first actuator to control the opening and closing of the valve group; the valve body 1 is welded with a valve seat 2 that matches the valve group switch ball 3 . The flow control sphere 5 is arranged inside the valve body 1 and is located at the other end of the valve body 1. When the flow control sphere 5 and the valve group switch sphere 3 are fully open, the axes of ...

The invention discloses a flow-controllable double-ball special ball valve bank for powder slag. The flow-controllable double-ball special ball valve bank mainly comprises a valve body, a valve bank switch ball and a flow control ball. The valve bank switch ball and the flow control ball are sequentially arranged in the valve body in the medium flowing direction at the same time, the valve bank switch ball controls opening and closing of the whole valve bank, flow control is achieved through the flow control ball in the non-completely-closed state, and the medium flow is determined by the opening degree of the flow control ball. The opening degree of the ball body can be controlled by adjusting the flow, and the purpose of adjusting the flow is achieved. In the normal use process, the flow control ball body keeps a certain opening degree, and the opening degree of the flow control ball body can be adjusted in the non-use state so as to meet other flow requirements. The ball valve bank is novel and reasonable in structure, hard sealing is formed between the flow control ball body and the valve seat corresponding to the flow control ball body, scouring of impurities to a ball body sealing structure under the severe working condition can be effectively relieved, the overall service life of the ball valve bank special for powder slag is prolonged, and practicability is high.
Description
technical field [0001] The invention belongs to the technical field of valves, and relates to a special ball valve for powder and slag, in particular to a flow-controllable double-sphere special ball valve group for powder and slag. Background technique [0002] With the development of valve technology, the industry has higher and higher functional requirements for powder and slag special ball valves used in media containing particles and impurities, such as liquid or gas media containing particles of 0.1mm-6mm. The valve is required to meet the zero leakage standard, and the flow rate needs to be adjusted under actual working conditions. In some cases, the full diameter of the pipeline is also required. Most of the existing ball valve structures control the flow by adjusting the opening of the ball. However, due to the tightness of the existing special ball valve for powder and slag, it is composed of a hard sealing system and a soft sealing system. , because the particle...
