The present utility model will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a linkage three-way butterfly valve comprises a valve body 1. One side of the valve body 1 is provided with a middle pipeline 2 which is communicated with the middle part of the valve body 1. Inlet and outlet pipelines 3 are respectively arranged on two sides of the valve body 1. The inlet and outlet pipeline 3 and the middle pipeline 2 can be used as an inlet of the inlet fluid and an outlet of the outlet fluid.
As shown in fig. 2 and 3, a main butterfly plate 4 and a sub butterfly plate 5 are provided in the valve body 1. When the main butterfly plate 4 is opened, the auxiliary butterfly plate 5 is closed at the moment, the middle pipeline 2 is communicated with the inlet and outlet pipeline 3 on one side of the main butterfly plate 4, and when the auxiliary butterfly plate 5 is opened and the main butterfly plate 4 is closed, the middle pipeline 2 is communicated with the inlet and outlet pipeline 3 on one side of the auxiliary butterfly plate 5. At least one of the main butterfly plate 4 and the auxiliary butterfly plate 5 is in an open state, and the other is in a closed state.
Wherein, main axis of rotation 6 and vice axis of rotation 7 are connected with to main butterfly plate 4 and vice butterfly plate 5 axle center department. The main rotation shaft 6 and the auxiliary rotation shaft 7 are respectively provided with a driving gear 8 and a driven gear 9. The driving gear 8 and the driven gear 9 are meshed with each other. The driven gear 9 can be driven to rotate when the driving gear 8 rotates. The rotation angle is defined to be 90 degrees or less.
The driving gear 8 is connected with an electric actuator 10, i.e. a driving motor connected with a valve, and the like, and is used for driving the main rotating shaft 6 to rotate. When the main rotating shaft 6 rotates, the driving gear 8 can be driven to rotate, and the rotation angle is 90 degrees at most. At this time, the main butterfly plate 4 and the auxiliary butterfly plate 5 are opened or closed by the back and forth 90-degree rotation of the driving gear 8. By arranging the driving gear 8 and the driven gear 9, the action states of the main butterfly plate 4 and the auxiliary butterfly plate 5 are synchronous actions, and compared with the mode of adopting a plurality of butterfly valves to control the flow direction in the prior art, the three-way butterfly valve adopted by the utility model has the characteristics of simple and compact structure, good synchronous opening effect of the actions of the main butterfly plate 4 and the auxiliary butterfly plate 5 and good synchronous sealing performance, and is convenient to control, small in volume and small in occupied area compared with a plurality of butterfly valves.
Optimally, the driving gear 8 and the driven gear 9 are both quarter gears with 90 degrees, and when the driving gear 8 exceeds the rotation angle of the meshing part, the driven gear 9 cannot be driven to rotate, so that the limiting effect is achieved, the synchronous action precision is ensured, and the failure rate is reduced.
The whole working process comprises the following steps:
as shown in fig. 4 and 5, the three inlets and outlets of the valve body 1 are respectively an inlet and outlet a end, an inlet and outlet B end and an inlet and outlet C end. The three inlets and outlets can be used as inlets or outlets. The utility model takes the inlet and outlet C end as the inlet, and the A end and the B end as the fluid outlet. When the actuating mechanism drives the main rotating shaft 6 to rotate, the main rotating shaft 6 rotates to drive the driving gear 8 to rotate, so that the inlet and outlet end B is closed, the inlet and outlet end A is synchronously opened, and at the moment, the end A is communicated with the end C, and the fluid flow direction is C-A. As shown in fig. 4 and 6, when the actuator drives the main rotating shaft 6 to reversely rotate and reset, the inlet and outlet A ends are closed, and the inlet and outlet B ends are synchronously opened, at this time, the B ends are communicated with the C ends, and the fluid flow direction is C-B. The change of the fluid flow direction is realized, the whole process is synchronously carried out, and the synchronous action and the synchronous tightness are better.
The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
