The two outlets of the existing three-way valve are respectively provided with a power executing element for controlling the position of the valve core, so that the manufacturing cost is high, and the installation and debugging are also troublesome.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a three-way valve convenient to installation and debugging, low in manufacturing cost is provided.
In order to solve the technical problem, the utility model discloses a technical scheme as follows:
the three-way valve comprises an inlet pipe and two outlet pipes, wherein a valve plate is arranged in each of the two outlet pipes, and the valve plates are arranged in the corresponding outlet pipes through rotating shafts; the rotating shafts of the two valve plates extend to the outside of the outlet pipe, and the end parts of the rotating shafts are respectively fixedly provided with a connecting plate, wherein the middle part of one connecting plate is provided with a connecting shaft which is fixedly connected with an executing element; two parallel connecting rods are arranged between the two connecting plates, and the end parts of the connecting rods are hinged with the end parts of the connecting plates.
In the technical scheme, the two connecting plates and the two chain plates form a parallelogram link mechanism, the link mechanism drives the two valve plates to synchronously rotate, and only the installation states of the two valve plates are set to be mutually vertical, when an actuating element works, one valve plate is changed from a vertical state to a horizontal state, and the other valve plate is changed from the horizontal state to a vertical state, so that the on-off of the two outlet pipes can be controlled.
Through the technical scheme, the beneficial effects of the utility model are that: the power of one actuating element is transmitted to the valves of the two outlet pipes by arranging the connecting rod mechanism, so that only one power element is required to be arranged on one three-way valve, and the manufacturing cost of the three-way valve is reduced.

FIG. 2 is a cross-sectional view of the outlet tube disclosed in the first embodiment;
fig. 3 is a structural view of a three-way valve disclosed in the second embodiment.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example one
Referring to fig. 1, the three-way valve includes an inlet pipe 10 and two outlet pipes 20, wherein the two outlet pipes 20 are located on the same side of the same inlet pipe 10, and the inlet pipe 10 forms a Y-shape. Each of the two outlet pipes 20 is provided with a valve plate 30, and the valve plates 30 are installed in the corresponding outlet pipe 20 through rotating shafts; the rotating shafts of the two valve plates 30 extend to the outside of the outlet pipe 20, and the end parts of the rotating shafts are respectively fixedly provided with a connecting plate 40, wherein the middle part of one connecting plate 40 is provided with a connecting shaft which is fixedly connected with an electric, pneumatic or hydraulic actuating element 50; two parallel connecting rods 60 are mounted between the two connecting plates 40, the ends of the connecting rods being hinged to the ends of the connecting plates 40. The two connecting plates 40 and the two chain plates form a parallelogram link mechanism, the link mechanism drives the two valve plates 30 to synchronously rotate, and as long as the installation states of the two valve plates 30 are set to be mutually vertical, when the actuating element works, one valve plate 30 is changed from a vertical state to a horizontal state, and the other valve plate 30 is changed from the horizontal state to the vertical state, thereby controlling the on-off of the two outlet pipes 20. The valve which transmits the power of one actuating element to two outlet pipes 20 through the connecting rod mechanism is arranged, and only one power element is arranged on one three-way valve, so that the manufacturing cost of the three-way valve is reduced.
Referring to fig. 2, the outlet pipe 20 is provided inside with a semicircular upper limit 70 and a semicircular lower limit 80, the bottom of the upper limit is in contact with the upper end surface of the valve plate 30 by a chamfered surface, and the top of the lower limit is also in contact with the lower end surface of the valve plate 30 by a chamfered surface, so that the sealing performance of the valve is improved.
Example two
Referring to fig. 3, the three-way valve includes an inlet pipe 10 and two outlet pipes 20, and the two outlet pipes 20 are vertically disposed. Each of the two outlet pipes 20 is provided with a valve plate 30, and the valve plates 30 are installed in the corresponding outlet pipe 20 through rotating shafts; the rotating shafts of the two valve plates 30 extend to the outside of the outlet pipe 20, the end parts of the rotating shafts are respectively fixedly provided with an L-shaped connecting plate 40, the middle part of one connecting plate 40 is provided with a connecting shaft, and an electric or pneumatic or hydraulic actuating element is fixedly connected with the connecting shaft; two parallel connecting rods 60 are mounted between the two connecting plates 40, the ends of the connecting rods being hinged to the ends of the connecting plates 40. The two connecting plates 40 and the two chain plates form a parallelogram link mechanism, the link mechanism drives the two valve plates 30 to synchronously rotate, and as long as the installation states of the two valve plates 30 are set to be mutually vertical, when the actuating element works, one valve plate 30 is changed from a vertical state to a horizontal state, and the other valve plate 30 is changed from the horizontal state to the vertical state, thereby controlling the on-off of the two outlet pipes 20. The valve which transmits the power of one actuating element to two outlet pipes 20 through the connecting rod mechanism is arranged, and only one power element is arranged on one three-way valve, so that the manufacturing cost of the three-way valve is reduced.
