The model utility content
Provide a kind of three-way discharging device in order to solve the problems of the technologies described above the utility model, purpose be for provide in the alumina production pipeline installing engineering a kind of effectively, convenient, practical three-way discharging device, solve that a discharging point is a pipe arrangement complicated problems under two transfer pump feed conditions in the production process.
In order to solve the problems of the technologies described above, the utility model is achieved in that a kind of three-way discharging device, and it is to be made of totally two gate valves, two shared valve bodies of gate valve, and valve body is provided with valve port and lower valve port, and the top hollow space of valve body is the sub-material chamber.
Described gate valve is a Wedge gate valve.
Described upward valve port is one.
Described lower valve port is two.
Described lower valve port directly is not communicated with, all corresponding wedge-type flashboard of each lower valve port.
Described wedge-type flashboard is connected with handwheel by valve rod.
Described wedge-type flashboard is connected with pneumatic actuator.
Described lower valve port is arranged in parallel.
Described lower valve port is arranged greater than 0 ° of angle less than 130 °.
Described sub-material chamber is arranged between wedge-type flashboard and the valve body.
A kind of three-way discharging device that has double-valve structure, its main body is made up of two Wedge gate valve.The valve body of two Wedge gate valve links together, and contains the sub-material chamber between wedge-type flashboard and valve body simultaneously, has opened three valve ports on the valve body.After flow of liquid enters the sub-material chamber by last valve port mouth, flow out by lower valve port, and it is consistent with the direction of incoming flow to go out the direction of materials flow via the on-off action of flashboard.
Advantage of the present utility model and effect are as follows: its working principle is simple, reliable; Simple in structure, the life-span is long, cost is low, easy for installation, very high promotional value is arranged in alumina producing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, handwheel; 2, valve rod; 3, valve body; 4, wedge-type flashboard; 5, sub-material chamber; 6, go up valve port; 7, lower valve port.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
The utility model three-way discharging device, tripper totally are to be made of two Wedge gate valve.Two shared valve bodies 3 of Wedge gate valve.4 on valve body 3 and wedge-type flashboard contain sub-material chamber 5.Open three place's valve ports on the valve body 3, promptly gone up valve port 6, two lower valve ports 7 for one.Two Wedge gate valve are except a shared valve body 3 and a shared last valve port 6 and independently connect and driving mechanism.Two corresponding lower valve ports 7 of wedge-type flashboard 4 difference; Two lower valve ports 7 directly are not communicated with.Two lower valve ports 7 can be arranged in parallel, also can be to arrange greater than 0 ° of angle less than 130 °.
Above-mentioned Wedge gate valve can adopt handwheel 1 operating valve to open and close, and promptly wedge-type flashboard 4 is connected with handwheel 1 by valve rod 2.Wedge gate valve can adopt handwheel 1 that the pneumatic actuator control valve also can be installed and open and close, and promptly wedge-type flashboard 4 is connected with pneumatic actuator.
